This is another video from the “do it yourself” series. And today we will install electric roller shutters for the garage. To replace old heavy ones iron gate, such nice roller gates will come.

To begin with, I will attach two profile pipes inside the metal garage. The guide roller shutter and box will be attached to these pipes. IN in this example the box will be mounted inside the garage. The profile pipe must be installed perfectly level. And here is the second profile pipe, which is installed on the other side.

What are roller gates made of?

Let's look at the composition of rolling gates. This is a box with a lid, a roller shutter and two guides. In addition, the kit will include such a block for remotely opening the gate, springs for attaching the leaf to the shaft and decorative plastic caps that will cover the holes in the places where the roller shutter guides are attached.

Remove the box cover and inspect the structure. Inside we see a shaft with rings on which the roller shutter fabric will be wound. Inside the shaft there is an electric motor, from which this wire extends.

Gate installation

The drive of these roller shutters is additionally equipped with a device for emergency opening/closing of roller shutters in the absence of electricity. Let's unpack and inspect the guides. The peculiarity of these guides is that their ends have already curved edges for better sliding of the blade. Now we insert the guide into the corresponding protrusions on the box. In other designs, an additional plastic guide may be present here.

Let's do the same on the other side. The bend on the guides should point towards the shaft. We lift the box with the guides and simply attach it to the gate frame. At this stage, it is important to make sure that the guides are installed strictly vertically and the box is strictly horizontal. To do this, we will use a regular level. Next, we will make markings for fastening the guides.

On the left guide I mark with a pencil the places for drilling closer to the left side. I will make the lower and upper holes at a distance of about 15 centimeters from the edge. For one guide I will have 4 mounting holes. I will attach the guides to self-tapping screws with a press washer. Before drilling holes, check the level again. First I use a drill with a diameter the size of a self-tapping screw. I'll drill both walls of the guide. Now using a drill with a diameter of 1.8 millimeters, I drill out only the front wall of the guide. A self-tapping screw will be inserted through it, and then the hole will be closed with a decorative cap. I tighten the self-tapping screw with a press washer.

Drilling must be repeated for all marked locations. Sometimes it is convenient to prepare the holes for the guides before installing the box. In addition, it is necessary to secure the box body itself with a self-tapping screw on the left and right sides.

Now you can delete protective film from the guides and insert and insert decorative caps into the holes.

We will drill a hole at the end of the box to bring the electric motor cable out. Distribute the rings evenly along the length of the shaft.

On next stage It is necessary to carefully insert the roller shutter curtain through the shaft into the guides. The blade starts starting from the bottom strip. This is a rather labor-intensive operation and it is advisable to have an assistant. Next, traction springs are put on the upper edge of the canvas. They have special fastenings, so they are worn in only one position.

The springs also need to be distributed evenly across the canvas. Now we fix the edges of the spring into the perforation holes on the shaft. This is how it is done. Carefully secure each spring.

Now we can check the operation of the electric roller shutter drive. There are 4 wires coming from the electric drive. The yellow-green wire is grounding. And the combination of blue, brown and blue-black wires will make the motor rotate in one direction or another.

Thus, when connected to these contacts, the roller shutter will be lowered or raised. Our roller shutters contain a block remote control. Let's consider its composition. Inside there is a box with a board, fastening and insulating elements. The antenna of the unit is made in the form of a flexible wire. For reliable reception, it must be taken outside the box and leveled. The electrical board has terminal blocks through which the connection will be made. Inside the box with the remote control unit there are detailed connection instructions. All connection options are available in it.

At least one remote control is required for the remote control unit to operate. Here's what it might look like.

To bind a new remote control to this control unit, you need to enter it into the memory of this device. There is a button with the “P” icon for this. A long press on this button switches the device to the recording mode for a new remote control.

After pressing, the signal LED will light up. At this moment you need to press the button on the remote control. This remote control is entered into memory and now you can control the operation of the roller shutter from it.

On last stage it is necessary to adjust the final position of the web. To do this, adjust the upper and lower position limit switches. Use a regular hexagon to turn the adjusting screws. An arrow with a plus increases the duration of rotation, and an arrow with a minus reduces the duration of rotation in one direction or another. The adjustment is made with the electric motor turned on. The lower position is adjusted until it touches the floor, and in the upper position it is recommended to make one and a half strips of fabric.

These are all the basic operations for installing roller shutters and there is nothing complicated about it.

If you intend to install a protective structure on the gate of a house or garage, we recommend that you pay attention to roller shutters Garage Doors, which in some parameters and performance characteristics are superior to similar systems. You will be pleasantly surprised by the simple design and operating principle of the security gate, as well as the possibility of manual installation.

Roller shutter systems - design and principle of operation

The first thing that attracts you in the design of roller gates or roller shutter gates is the compactness and originality of the system - protective roller shutters rise to the ceiling of the garage or building and are hidden in a special box.

Moreover, mind you, it does not at all overload the space near the garage or the entrance gate to the house, which allows you to install gates where you need to save on the territory.

Naturally, this expands the scope of use and application of automatic rolling gates. Moreover, the design of roller gates and the operating principle of the models are identical.

Exaggerated and enlarged, the algorithm for installing roller shutter gates is as follows.

The roller shutter, assembled from aluminum slats arranged horizontally, moves along guides using traction springs. To close the gate opening, the leaf is deployed using a manual or automatic drive and is fixed at the extreme point with a locking device.

In addition to the roller shutter curtain, the following are involved in the functioning of the system:

• drive unit
• side guides
• box or casing to hide the canvas
• fastening and connecting elements of the system.

However, despite the apparent simplicity of the device, one should not forget about the difficulties of installing roller shutters, which depends on the location and fastening of the roller shutter box.

installation and assembly methods

Roller gates and automatic roller gates can be installed in the following ways:

• overhead installation of the box
• wall-mounted
• lintel

Overhead installation is considered the simplest and most accessible for doing it yourself. It consists of attaching a shaft (outside or inside) and guides above the garage doorway to ensure the movement of the door leaf.

Interior(built into the wall) installation can be considered universal, ensuring installation in any geometry of openings without changing or distorting architectural view building. In this case, the gate design parts are well protected from precipitation.

Ceiling installation method can be attributed to decorative design garage or gate, because when this method a new lintel is created, placed 40 cm below the main one.

Useful tips

The usefulness of choosing the method of installing the box is determined by the design of the facade of the house or structure. Overhead outdoor installation preferable for houses equipped with roller shutters with external frame fastening. The overhead roller shutter system will be on topic. Protective roller shutters built into the wall are best option However, installation of the guides will require the creation of additional wall niches.

Do-it-yourself installation of overhead roller gates

We will tell you and show you the step-by-step manual installation and installation of roller garage doors using the system as an example Hormann RollMatic, consisting of a box with a shaft, two guides, an electric drive and remote control management.

Installation steps

Preparatory work

We remove old garage doors.

We carry out the installation profile pipes for subsequent fastening of the system guides.

We unpack and prepare the roller shutter curtain and guides.

We insert the guides into the bases of the box to try out the placement in place.

Marking gates for frames with an octagonal shaft

We attach the box with the shaft to the existing gate frame and level the vertical and horizontal positions.

We make markings for mounting and fastening the guides.

Installation of the box and guides

Using a drill of a smaller diameter, we drill holes in the guides and the wall.

Drill out the guide with a large drill.

We install and tighten screws into the resulting hole and close it with a press washer.

We fix the box body in place on the left and right.

Remove the protective film from the guides.

At the ends of the box we drill a hole for the electric drive cable to exit.

Hanging the canvas

We distribute the spacer ring holders along the length of the box shaft.

We lift and place the roller shutter curtain from the bottom strip onto the hooks of the holder.

We put traction springs on the upper edge of the canvas and distribute them evenly.

We fix the edges of the traction springs into the mounting holes on the shaft.

We check the operation of the electric roller gate drive.

Connecting the electric drive and remote control wires

Connecting the electric drive wires according to markings and colors, according to the diagram supplied by the manufacturer.

We connect the remote control unit through the terminal holes according to the instructions.

We bind and encode the data of the remote control unit into memory.

We tighten the adjusting screws with a hexagon to set the final position of the blade.

Useful tips on how to install roller shutters yourself are shown in the video.

It is advisable to install it on a garage yourself if there is sorely not enough space to open the gate leaves. This problem is often faced by garage owners in co-ops where the garages are located close to each other.

This garage door design is easy to use and requires virtually no hardware for installation. But, roller shutter gates also have serious disadvantages - they are easy to break into.

The operating principle is simple - roller mechanism and the cable system raises and lowers metal curtain gate These are metal blinds for the garage, which can be equipped with many convenient additional elements.

Basic equipment for garage roller shutters:

• door leaf, which can be made of durable steel or lightweight aluminum slats;
• vertical metal guides for web movement;
• the shaft on which the lamellas are wound is installed above the gate opening;
• the shaft is secured in a protective box, which prevents mechanical damage to the rolled roller shutter;
• electric or mechanical drive for raising and lowering the gate;
• locking bolts or automatic locking system.

When installing automation, the kit must include a gate unlocking lever. When there is no electricity, you can open the roller shutters by simply pressing the handle.

Additional equipment

For the comfort of using garage doors with roller shutters, you can purchase additional convenient accessories:

• remote control;
• automatically adjustable heating of the gate guides, which is indispensable in winter when the roller shutter leaf freezes to the frame;
• additional sealing of the box for noise and heat insulation of the garage.

The cost of a garage roller shutter depends not only on the selected components, but also on other important parameters.

Classification of garage roller shutters - what affects the cost of the gate

The simplest budget set of roller shutters for a standard garage will cost 7–9 thousand rubles without installation. The cost is influenced by the following factors:

• the material from which the door leaf slats are made. Steel is stronger and more durable, but is more expensive and heavier than aluminum sheets. If the garage is located in a guarded parking lot, then it is better to go with aluminum. The material is corrosion resistant and lightweight. A broken lamella can be easily replaced with a new one;
• The method of lifting the canvas is automatic, naturally more expensive than mechanics.

Advice. If you install roller shutter garage doors with your own hands, then it is more profitable to purchase a basic inexpensive set and purchase additional parts separately. For example, an automation unit for disassembly will cost half as much.

• degree of protection against burglary. Additionally, a motion sensor is installed that prevents the door from lowering when entering the garage, and turns on the alarm when intruders enter. The price of the sensor, depending on the manufacturer, is from 2 to 6 thousand rubles;
• roller shutter installation method.

Classification of roller shutter doors for garages according to the degree of protection of the room:

• type P1 - P2 - can protect the garage from dust and noise, but breaking such a gate takes a couple of minutes;
• type P3 - P5 - steel profile is more resistant to mechanical opening. This is the best option for garages in cooperatives and courtyards;
• type P6 - P8 - an armored version of the gate with bulletproof lamellas. It is expensive, but it is easier to install swinging metal gates.

If you decide to install roller shutter garage doors with your own hands, then you need to know which design according to the installation method you need to buy:

• overhead external gates - must be installed outside, the roller shutter box is located outside and is exposed to rain and wind - not the best option for installation. But, this type of structure can also be installed from inside the garage.

Advice. When purchasing roller shutters, immediately calculate the height, since you need space to mount the box into which the gate leaf is rolled up.

• built-in gates are the most reliable option, since the frame of the structure is installed in the gate opening and can be further strengthened;
• combined gates - it is necessary to make a special niche above the gate opening in order to install a box in which the rolled-up roller shutter will be placed.

The design principle is quite simple. What are the advantages and disadvantages of such garage doors?

Roller shutters - advantages and disadvantages

This design is profitable and convenient to install in garages that are located in a protected area.

Roller shutters have many advantages:

• convenient automation;
• easy gate opening using remote control;
• require virtually no space, suitable for garages with limited space;
• the structure is lightweight and does not bear any load on the walls;
• roller shutters can be installed in garages made of any materials;
• damaged lamellas can be easily replaced without high repair costs;
• The warranty on the gate is from 10 years, depending on the manufacturer. The Chinese do not provide guarantees;
• You can install a basic inexpensive kit yourself. The installation cost is usually 20 percent of the gate price;
• Additional insulation of roller shutters helps ensure complete tightness.

There are many options for decorating such garage doors; you can choose a spectacular and beautiful finish wood effect, fabric, with beautiful drawings and inscriptions.

Roller shutters also have many disadvantages:

• breaking such a gate is a couple of trifles, a security alarm is definitely needed;
• aluminum roller shutters are easy to damage, and steel ones are expensive;
• if you buy a standard set without insulation, then such gates will not retain heat, and it is impossible to insulate them yourself along the canvas;
• automation breaks down - repair is expensive.

If you decide to install roller shutter gates in your garage with your own hands and save up to 50 percent of the cost, then we offer detailed instructions on installation.

Step-by-step installation of roller shutters on garage doors

When purchasing roller shutters, you need to take into account that such garage doors are suitable for standard garages. Standard – aluminum structures are installed on a gate area of ​​up to 14 squares, steel gates - no more than 49 squares.

For installation, you need a standard set of tools - a screwdriver, drill, level, hammer drill, hammer and pliers. Sealing of joints is carried out with acrylic or silicone sealants, along the perimeter of the box, when installed in the opening, we seal it with polyurethane foam.

When purchasing garage doors of this design, it is important to correctly calculate required dimensions. Along the gate opening, the width and height of finished roller shutters should not be less than five millimeters. Be sure to check the dimensions diagonally as well; this requirement is important for old garages, where the gate opening may have been knocked down during laying.

Installation sequence:

• Be sure to level the garage opening with cement, remove all uneven surfaces, chips, and plaster cracks;
• we check the opening for level, where necessary, install rubber leveling gaskets;
• set the guides. To do this, we drill holes for fastenings on the metal side guides (50 cm increments). The diameter of the fastener is 8 millimeters.

Important. When drilling holes for fasteners, you need to retreat 10 centimeters from the edges of the guide.

• in the upper part of the guide frame we drill holes for plugs (diameter 11.8 cm);
• We assemble the gate frame - to do this, we fix marks in the opening at a level for fastening the frame (diameter 8 mm).

Important. If we install automation, then we immediately need to make another hole to connect the electric drive.

• Before hanging the box into which the roller shutter is rolled, we drill holes in it for fastening the lid. It is better to mark by attaching the lid and drilling both the lid and the box at once (the diameter of the lid fastener is 4.2 mm);
• We mount side rails on the frame along which the door leaf moves;
• Now we level the frame in the gate opening and make marks - where we will drill a hole in the wall for fasteners, do not forget about the automation cord;
• Now in the opening you need to drill holes for fastenings and install dowels on the sealant. We fasten the protective spring of the drive;
• hole for a mechanical drive, depending on the selected gate model - from 12 to 16 mm;
• Now you can fix the gate frame in the opening.

Important. Check the horizontal and vertical several times to ensure that the frame is not skewed.

Frame fastening elements are usually sold as a set, but it must be borne in mind that for brick and concrete walls dowels and anchors 3 cm long are needed, for hollow wall blocks - 6 cm, and in metal garages Roller shutters are attached to metal screws.

We tighten the fastening of the frame alternately, checking the level horizontally and vertically. After installing the frame, you can mount the automation and fasten lifting mechanism and the gate leaf.

To correctly install roller shutters in the garage with your own hands, watch the video, so the process is more clear.

From us, in a short time, you can buy reliable roller gates for a garage or cottage in Moscow and the Moscow region at a price of 4,800 rubles per square meter.

Rolling gates are widely in demand in Moscow and the Moscow region. They owe their name to the main design feature– during use, they are wound into a roll located above the opening.

Application area similar systems is quite wide, but most often clients decide to buy roller garage doors. In our company this can be done at a special price from 4800 rubles per square meter. Specially designed kits designed specifically for garages will reliably serve for many years. With proper and timely maintenance, there is virtually no risk of failure. Among the advantages of the application, I would like to note the main most obvious ones:

• Dimensions

The entire structure is compact and takes up minimal space. While installation alternative systems often causes a lot of difficulties due to lack of space, roller garage doors can be the only possible solution. A common problem at sites is the presence of pipes, communications, load-bearing beams and floors in the work area.

• Reliability

Basic complex structural elements hidden from external environment under the box, due to this it was possible to achieve reliable operation even in difficult weather conditions.

• Exterior

Rolling garage doors will decorate the facade of the building and give a modern look to the entire home. If you plan to install roller shutter systems on windows in the building, then the overall concept and harmony will be fully respected.

• Availability

At your discretion, our managers will help with the selection of budget equipment, providing favorable purchasing conditions. You can buy roller gates quite inexpensively only by using the basic configuration.

What are roller garage doors made of?

1. Roller profile

The main visible part of the structure consists of a roller shutter profile, which in this case is reinforced and designed for large openings and strong winds.

Rollforming profiles.

For roller gates, a special profile with foam inside AG77 from the Alutech company is used. The presence of foam filling allows it to be installed even in heated rooms without much heat loss. The opening width can reach 7 meters.

Extruded profiles.

Their use is justified relatively small structures in the absence of heating in the room. Thanks to the thick wall and additional partition, it can withstand heavy mechanical loads. The size of the box at the same opening height for such profiles will be smaller than for AG77.

2. Protective box

Performs decorative and protective function. Makes access to the shaft difficult for potential burglars or vandals.

3. Octagonal shaft

Is important detail system, as it takes on most of the weight of the roller shutter. Depending on the availability of automation, a spring-inertial mechanism or an electric drive can be inserted into the shaft. Based on the calculation in the program, the product can be equipped with various shafts, which differ in size and metal thickness.

4. Bottom roller shutter profile

Provides additional wind resistance and stability of the product. In its lower part there is a groove for threading a sealing insert made of plastic or in the form of a brush.

5. Guides

The roller shutter profiles move up and down along them.

How to choose the opening method?

Based on the type of control, we can distinguish automatic roller gates with an electric drive and mechanical ones with a spring. The dimensions of the opening can reach decent values, so manual control can be difficult. In addition, the cost of a standard tubular motor is very close to the price of springs. For these reasons, automation is almost always worth the purchase. For comparison, we will prepare an order calculation in two versions, thereby simplifying your choice. Control from the remote control is implemented practically without interfering with the wiring, because the signal receiver is installed directly into the box.

Installation of roller shutters can be carried out on top of the opening or inside between the slopes. In either option, the estimate will be almost the same, so when choosing, it is better to start from visual preferences and technical aspects facade of the building. It is also worth deciding on which side of the wall to install. If the box is placed indoors, then the critical elements will be warm and dry, which will have a positive effect on the service life of the system.

Color palette

When choosing a color, find the one that best suits your façade! Usually combinations are achieved with the roof, drainage system, filing eaves overhangs or a fence. You can always find something interesting and individual. The unique wood-look paint is designed to please special connoisseurs.

You can buy roller gates in several stages:

1. Application on the website or by phone.

2. Preliminary calculation and budgeting if necessary.

3. Surveyor’s visit and final price agreement.

4. Conclusion of an agreement and preparation of documents for transferring the order to work.

5. Production.

6. Installation on the agreed day.

The domestic market of entrance and garage doors is represented by swing, sliding, up-and-over, sectional and, finally, roller structures, each with its own advantages and disadvantages. But if the choice is dictated by scarcity free space- roller shutter systems are in demand, and they will be discussed in the article.

Let's first look at the pros and cons of roller garage doors

Advantages of roller gates

• They do not require free space to open either in front of the opening, or on the side of it, or inside the garage
• Easy to open after snowfall
• Do not limit visibility when leaving and do not interfere with maneuver
• Can be equipped with a relatively inexpensive electric drive
• Safe to use
• In the exterior of the house they go well with window shutters
• Suitable for arched openings (it is possible to attach the box to the wall from inside the garage)

Disadvantages of rolling gates

• Lose to other designs in strength and resistance to burglary
• Compared to sectional models, they insulate heat worse
• Requires protection from precipitation, does not function well when icing
• When installed as entry gates, they form a horizontal obstacle that interferes with the movement of freight and fire-fighting vehicles
• You cannot cut a gate into the canvas

Methods for installing roller gates

To install roller (or otherwise roller) garage doors, you need very little space under the lintel or on the wall above the opening. IN open position Unlike traditional doors, they do not block the street, do not interfere with maneuvers when entering and exiting, and do not slam shut from gusts of wind.

At one time, roller shutter systems successfully competed with sectional systems, but lost to them, since they are less durable and provide poorer protection from the cold (due to the presence of multiple connections and thinner sheets).

But roller shutters, like sections, do not need space under the ceiling or against the wall of the garage, which means that nothing limits you when arranging this room. You can install spacious shelving, and lift large equipment, such as a boat, snowboard or surfboard, to the ceiling on cables.

Rolling gates will cope, albeit with some reservations, with security at the entrance to the site. They are easy to install, and their price is quite affordable, even taking into account the automation systems. However, these structures are manufactured mainly according to individual order, and you will have to actively participate in the process (even if not in deed, but only in word) in order to select the main components and accessories, as well as the installation method, because both the convenience and service life of the product depend on this.

CANVAS IN PROFILE

The main visible part of a roller shutter gate is the leaf, which consists of many narrow, horizontally oriented profiles (slats), which are fastened to each other using a longitudinal hook lock.

A special end piece is installed on the lower edge of the leaf to ensure a tight fit to the floor (and in some cases, to lock the gate), and on the upper edge there is a reinforced piece for fastening to the shaft. The lamellas are made from aluminum strip by roller rolling or extruded from the melt. Their cross-sectional dimensions and wall thickness are approximately one and a half times greater than those of window roller shutter parts, because the lock must withstand significant weight, and the entire canvas must withstand serious wind loads.

Extruded profiles are hollow, but have internal stiffening ribs, so they are stronger than rollforming ones. filled with polyurethane foam.

For unheated room You can order canvases with ventilated or so-called viewing inserts. The former have narrow slits protected from moisture penetration, while the latter have small “windows” with polycarbonate inserts for natural light garage.

The most durable canvases are those made from steel profiles with a wall thickness of 0.5 mm. But in terms of corrosion resistance, steel lamellas

inferior to aluminum ( the slightest damage coatings lead to the appearance of paint blisters and rust spots). In addition, such canvases make a lot of noise when opening and closing, as well as during rain and hail. Finally, they are significantly heavier than aluminum and therefore require a more powerful drive.

Not only the resistance of the structure to burglary and wind loads, but also its maximum dimensions depend on the type of profiles used. Let's say, the maximum width of a web (with a height of 2 m) from roller-rolled aluminum products is 2.5-4 m. For extruded aluminum - 4.5-7 m, for steel - 7-11 m.

INSIDE THE ROLLING GATE FRAME

In addition to the door leaf, the door delivery set includes a shaft, its casing (box), side guide rails, a drive (manual or electric) with transmission, as well as fastening and connecting parts. All elements with the exception of the electric drive must be from the same manufacturer - otherwise the structure simply cannot be assembled.

The shaft is steel, shaped like an octagonal prism, galvanized and rotates on two ball bearings. It can be installed stationary or movably - using a system of cantilever rails and roller carriages. The second option is preferable, since then the shaft, as the web unwinds, moves closer to the plane of the opening, due to which the lamellas are fed to the guides at a constant angle, which means they never jam and wear out less. It is also necessary that the design provide for emergency braking of the shaft (as in ALUTECH systems) in order to eliminate the possibility of a sudden lowering of the blade if the gearbox breaks down. IN production premises the shaft is often left open, but in private houses it is always covered with a protective and decorative casing, painted the same color as the canvas.

Guide bars are aluminum profiles U-shaped section with a wall thickness of 2-3 mm, into which the side edges of the canvas extend and are firmly held there due to a system of special locks, which significantly increases the structure’s ability to resist wind loads. In addition, tubular polymer or brush seals, protecting the unit from dust and dirt and ensuring silent movement of the blade. The range of guides is quite diverse, and the choice of one option or another depends mainly on the installation method (but more on that later).

A manual drive is not capable of providing the modern level of comfort, and these days it is installed only if electricity is not supplied to the garage or car box.

The main types of mechanisms that can be equipped with gates are cord and spring-inertia. Both of them are designed for the canvas to weigh no more than 80 kg. The first is a worm gear with a handle, which is attached to the wall at a height of about 1 m and connected via steel cable with a pulley on the shaft. The second consists of two or more tension springs mounted on guides and compensating the weight of the web, so that it is not difficult to lift it by hand. If the blade weighs more than 80 kg, a balancing mechanism with a powerful torsion spring placed inside the shaft will be required.

There is also a not very convenient drive - a crank, but it is used mainly for emergency opening of automated gates.

EFFICIENT GARAGE DOOR CONTROL

An inexpensive and practical electric drive in a cylindrical body has been developed for roller gates, which fits easily inside the shaft and is capable of operating from mains power. alternating current. The power of such a motor is 240-500 W. and this is quite enough to lift a canvas weighing 60-150 kg. The easiest way is to order the motor together with the gate - then it will be installed by specialists from the dealership during assembly. But on-site installation does not present any particular difficulties (however, if you do it yourself, the warranty period for the drive will be shortened). The cost of modern intrashaft drives from leading companies, such as Nice, FAAC and Somfy, starts from 3800 rubles. (without remote control).

For larger blade sizes and weights, an axial drive can be installed. It is attached to the wall on the side of the box and connected to the shaft through a coupling or by means of a chain drive. The price of axial drives is quite high (from 18 thousand rubles), but they still have unhindered access for maintenance and repair. (To remove the in-shaft model, you will need to remove the gate.)

Electric motors vary in noise level, maximum speed rotation (it varies between 8-14 rpm) and the type of limit switches (mechanical ones are cheaper, but electronic ones are easier to install and provide more high level security). Most drives are capable of operating without interruption for no more than th minute, which is equal to three-four opening-closing cycles. If you do overheat the engine, it will turn off for a while (10-15 minutes). In addition, you need to know that in cold weather (below -10 ° C) most inexpensive motors will function intermittently and at the same time sharply exhaust their service life or completely refuse to lift the canvas.

Almost all modern drives are protected by a thermal fuse. This saves the motor windings from short-circuiting, and the entire structure from damage in case of distortion or ice formation. However, when the end profile encounters an obstacle, the shaft continues to rotate, unwinding the web inside the box, which often leads to damage to the parts. Therefore, systems with a “smart” control unit are preferable - it allows you to adjust the maximum torque.

The sensitive edge of the door leaf - a hollow rubber tube with a compression sensor inside - will allow you to take your driveway and garage door system to the next level of security. It will stop the drive even upon slight contact with an obstacle. Photocells installed in the opening or in front of it on special posts will allow you to detect interference in advance. They cost much less than the sensitive edge, but they are noticeably inferior to it in reliability.

The command to the electronic control unit (for tubular drives it is often built-in, and for axial drives it is remote) is given from a mobile or stationary remote control. Modern remote controls are miniature radio transmitters with a range of at least 50 m, emitting a floating coded signal. At the same time, the number of remote controls for one control unit is practically unlimited.

As a backup control, you can install a stationary panel on the inside on a fence or garage wall, and a switch with a key or code buttons on the outside. If you want to control both the gate and all the roller shutters in the house from one remote control, you should purchase a wireless device that can issue commands to several control units at once, for example Chronis RTS L, Telis k RTS (Somfy), Ergo, Piano (Nice).

The chain drive is usually hidden inside the box (a), but when the shaft is installed openly, it is placed inside a special casing (6). The tubular drive does not require additional protection from dust (c). Uniform flow of profiles onto the shaft is ensured by special rollers

THREE INSTALLATION OPTIONS FOR GARAGE ROLLER DOORS

Rolling gates can be installed in three main ways: overhead, lintel and built into the wall. They differ in labor intensity and results. The overhead method is considered the simplest: a shaft is attached to the wall above the opening (from the inside or outside), and guides are attached to the sides of it. TO outdoor installation usually used in houses equipped with roller shutters (the frames of which are never secured from the inside) to maintain the integrity of the facade pattern. Internal installation is more universal (suitable for openings with any geometry), does not introduce unnecessary elements into the architectural appearance of the building, and the structural parts are better protected from precipitation. The lintel method involves fastening the shaft at the top of the opening. Actually decorative box forms a new lintel, which is 35-40 mm lower than the base one.

It does not protrude beyond the plane of the wall, and it can even be hidden under sheathing material, such as siding. Alas, it will be possible to resort to such a scheme only if initially high altitude opening (from 2400 mm). Embedding into a wall is a complex, time-consuming method, which is rarely used in the case of gates due to large sizes box sections (from 250 * 250 mm).

You need to think about the possibility of implementing it even when designing the building. A niche for the box is provided above the opening; later it is covered with brick, or covered with clapboard, or the box is simply plastered together with the wall so that it becomes invisible neither from the inside nor from the outside.

When lowered, the canvas seems to move out of the wall, which looks very impressive. And when the shutters are open, their presence is indicated only by guides screwed to the slopes, and even these can be easily hidden, for example, with a layer of plaster. However, there are also disadvantages here: the drive mechanism turns out to be practically inaccessible, and in cold weather it is possible that the section of the wall above the window (at the location of the niche) may freeze.

Installation options for roller shutters: under the lintel (a), internal overhead (6), external external (c)

Installation of roller gates at the entrance to the site

The practice of installing roller gates at the entrance to a site is not very common, but it still exists, which confirms the operability of the system in street conditions. Here, a strong competitor to the roller shutter is console sliding design , which has almost the same set useful qualities and at the same time much more massive and tougher. However, it requires a foundation laid to the depth of soil freezing, and free space on the side of the opening (there should be no buildings, trees or other obstacles there). Installing rolling gates is much easier, and they will cost less. But to do this, you will have to solve a number of problems, the main one of which is: how to ensure the geometric stability of the opening? After all, the slightest distortion will certainly cause the web to jam when moving along the guides.

First of all, the pillars will have to be installed on a single foundation - it does not have to be deeply buried, but it must be well reinforced. In addition, the racks at the top need to be connected by a jumper, preferably a powerful steel beam. It is also worth building a roof over the gate, which will protect the leaf from precipitation and prevent moisture from getting inside the casing to the shaft and drive.

For automation street gate It is allowed to use both internal shaft and axial drives with a high protection class (for example, IP44).

Garage door assembly (on the floor - before installation)

When installing a garage roller door structure, a kind of U-shaped frame is first assembled on the floor. His top part a box1 (1) is formed with a shaft (2) already installed inside, and the sidewalls are formed by guide rails (3). Then this portal is attached to the walls, the canvas (4) is wound on the shaft, lowered and raised, setting the extreme positions

Additional Information

Resistance of roller gates to wind loads- one of their most important parameters, when determining which one should focus on SNiP 2.01.07-85 “Loads and impacts” and GOST R 52502-2012 “Metal roller blinds. Specifications" The first document introduces zoning according to wind loads, and the second - wind resistance classes of roller shutters. It is important to take into account that when calculating the maximum width of the opening to be closed, some manufacturers take as a basis the minimum value of wind pressure (50 Pa), and such roller shutters will not withstand the onslaught of stormy winds! In the CIS, the most common are the 2nd and 3rd wind regions with loads of up to 300 and 380 Pa, respectively, according to SNiP 2.01.07, which correspond to class 5-7 roller shutters according to GOST R 52502-2012.

DO YOU NEED A LOCK FOR ROLLER ROLLER GARAGE DOORS?

Generally speaking, the drive handles the function of the locking mechanism quite well. However, it still allows you to slightly (3-7 cm) raise the canvas. Therefore, to increase

To ensure resistance to burglary, a special end profile with side crossbars and a cylinder is sometimes installed. This type of lock is used to close the garage at night and during long absences. And gates with balancing springs and without an electric drive are required to be equipped with it.

IF THE LIGHTS TURNED OUT

When the power goes out, the drive blocks the shaft, preventing the gate from opening. The possibility of engine or transmission failure cannot be ruled out. An emergency release, controlled from the inside by a rod and from the outside by a key, will allow you to open a gate with a spring mechanism in any situation.

This is a kind of neutral gear that allows you to disconnect the engine from the shaft and raise the blade with your hands. The design without springs should be equipped with an electric drive with the ability to rotate the crank (note that the service life of the crank gear is very small - only 40-60 opening/closing cycles). But in this case it is only possible internal installation box, and you can only open the gate manually from the side of the room, which means you can’t do without a gate or door connecting the garage to the house. Another option is to move the loop under the knob outside, hiding it behind a lockable hatch.

On a note:

Depending on the location of the box, the slats can be facing the street with their convex or concave surface

Aluminum profiles painted polymer compounds, resistant to moisture, ultraviolet radiation and mechanical damage; the most popular is a single-color finish, and the surface can be smooth

woven or shagreen, with a characteristic relief

When using the lightest roller-rolled profiles, 1 m2 of roller door leaf weighs only 4.7 kg; in combination with extruded profiles, its weight can reach 7 kg or more. The weight of garage doors rarely exceeds 80 kg, and yet a falling door can cause injury or damage the car, so the structure must be equipped with a braking mechanism.

There are profiles for rolling gates rollforming(with polyurethane foam filling) and extruded(ventilation and inspection)

Rolling gates do not open and close too quickly, and the cycle cannot be repeated many times in a row. Therefore, they should be used only for the entry and exit of vehicles, providing gates to the site and to the garage.
