Faced with construction country house It becomes clear - monolithic and brick are durable, but construction and operation are expensive. Frame is more affordable, but wood is short-lived. We do not consider technologies with questionable safety for health - glued, with foam plastic, etc.
How to find a balance between the cost and quality of housing being built? Which house is optimal? The solution is metal frame houses LSTK (LSTK - Light Steel Thin-Walled Structures).
There are different types of metal frame houses, we strongly recommend using the benefits scientific achievements in the production of metal frames and use thermal profiles. The thermal profile made it possible to obtain metal frames equal in thermal conductivity to wooden frames. Cold bridges are successfully broken by applying thermal cuts to structural parts. We use an effective 8-row thermal cutting of profiles, developed by Finnish specialists. Thermophysical studies confirmed effective reduction thermal conductivity by cutting out strips of metal - thermal cutting.
Important: Metal construction frame house using a thermal profile does not require the cost of thermal insulation of the frame on the facades and roof!
Metal projects frame houses on our website differ from similar selections on other resources - they were designed and built by our own design department. Many projects of metal frame houses have been implemented more than once.
How metal frame houses are built is shown in the gallery of completed works by LSTK photo. Metal frame houses receive positive reviews from owners, video.
Low-rise metal frame houses are popular all over the world. According to statistics, housing construction on a metal profile frame occupies 80% of all buildings. The main consumer regions of this technology are Scandinavia, the USA, and Canada.
Such houses have many advantages compared to capital buildings and houses built on a wooden frame.
Distinctive features of metal frame houses:
- strength;
- durability;
- short construction periods of buildings;
- inertness to weather and climatic conditions;
- low cost;
- resistance to heat loss;
- high fire safety;
- seismic resistance;
- environmental friendliness;
- freedom in choosing architectural solutions;
- non-shrink technology.
The iron frame, its elements - light steel thin-walled structures, consists of galvanized profiles and thermal profiles, fastening strips and plates for assembling the frame, different types corners. They are not subject to rotting, withstand temperature changes, precipitation, and are resistant to the elements. A steel profile can serve as the basis of a structure without damage for more than 100 years.
It is possible to construct a building on a frame made of LSTK within a month. The parts of the building base are lightweight, which eliminates the use of lifts and cranes. Fastening of frame parts is carried out using threaded connections. These include: self-drilling or tapping screws, bolted connections.
Features of houses on a metal frame
Frame house construction is not tied to the climate in the region. A metal frame for a house can be assembled in any climatic zone, the main condition for weather conditions is comfort for workers performing installation.
The emergence and development of technology for the construction of residential buildings on metal frames is caused by the need rapid construction low-rise buildings made of materials cheaper than wood and the ability to establish industrial production frame parts.
The final cost of a frame house made from a metal profile and sandwich panels is significantly lower than construction from brick, gas blocks, wood and ceramic blocks.
High thermal insulation characteristics of structures are ensured by high-quality insulation. Heating such buildings is much easier and more economical. Heat transfer resistance frame wall a thickness of 25 cm is equal to that of masonry with a thickness of 1.5 m.
Sandwich panels used in frame construction use mineral wool insulation. His temperature Range– -60…+400ᵒС. Characteristics wall panels make the house resistant to acids and other aggressive environments, temperature changes, fire. The material from which they are made does not accumulate moisture and is resistant to damage by rodents and microorganisms.
Mineral wool insulation is natural and environmentally friendly. Frame elements made from LSTC can be reused. This property is highly valued by mining companies that build rotational camps. This causes less damage to the regional ecology.
Due to the light weight of the base and sandwich panels, the buildings do not shrink. In buildings built using this technology, it is possible to use different architectural possibilities, since spans without installation intermediate supports can reach 14-24 m.
Disadvantages of a metal profile frame
Base from metal parts has several disadvantages.
- In the event of a fire, the galvanized iron base loses its rigidity, the building twists in a spiral, it falls and warps. This feature reduces the evacuation time for residents. A wooden beam, as opposed to iron, becomes charred under the influence of fire, but maintains its shape.
- Difficulty in installing built-in furniture and household appliances. To solve the problem, at the design stage, houses are determined with their installation locations, which are reinforced with additional profiles and wooden panels.
- Limited number of storeys in the house and the impossibility of using heavy building materials.
- High conductivity electric current metal frame. Protection against this problem is the potential balancing system.
Manufacturing and installation of frames from LSTK
The skeleton of the house is made of C- and U-profiles. They are connected with self-tapping screws. The pitch between the racks is 600-1000 mm. It takes into account the dimensions of the insulation panels and allows you to conveniently attach other finishing materials.
If a house is being built according to an individual project, then after its development and approval of all the nuances for the placement of furniture and household appliances in the premises of the future building, a 3D model of the house is made. This allows customers to see the final result in miniature. Upon completion of the registration process project documentation drawings are transferred to the factory producing the parts metal frame.
On the production line, each part is manufactured separately, numbered, and packaged. Finished parts are equipped with holes for fastenings and utility lines. To install the skeleton of the house, the base parts include connecting elements.
Buildings by individual projects are much more expensive than houses manufactured according to standard designs. To reduce the cost of housing construction, you can use a standard project with a frame made of thermal profiles or light steel thin-walled structures using Canadian technology. Its difference from other technologies quick construction buildings - a frame made of LSTK and special SIP panels with special thermal insulation characteristics.
In the case of housing construction standard project the customer receives a finished frame of a certain size and shape. The base parts are labeled and packaged according to the house drawings.
As insulation, except mineral wool, can be used:
- basalt slabs;
- expanded polystyrene;
- ecowool.
Brick and porcelain stoneware are used to decorate the exterior walls of the house. Hinged ventilated facades are often used as finishing for the facades of frame buildings. various types. Finishing materials such as siding and block house are becoming increasingly popular. Plastering and painting facade walls have not lost their relevance.
Complete with frame parts and connecting elements, the customer receives a description of the project, recommendations and instructions for assembling the frame, and a specification of all elements.
“Whatever they can come up with!” – perhaps this is the first thought of most readers who first encountered the concept of frame houses made of metal profiles. The use of metal as load-bearing structures It seems like a rather strange decision, but do not rush to conclusions - study all sides of the issue.
Metal houses – do you have any experience?
Metal products have been used as load-bearing structures for a very long time; numerous shopping centers and skyscrapers are prime examples of this. True, the technologies and materials used in the construction of such large objects do not justify themselves at all in private house construction - rolled metal products are very heavy, bulky, and are used to connect individual elements special technologies welding and riveting, you cannot build such a house with your own hands.
Everything changed when lightweight steel thin-walled structures—hereinafter referred to as LSTK—were invented. For such structures only thin steel sheets, formed into a Z-shaped profile with through grooves or perforations that should trap cold. This type of LSTK is also called a thermal profile, and if we talk about private construction, then it is advisable to use only it.
Of course, no matter what tricks manufacturers come up with, metal remains a material with high thermal conductivity. This fact in most cases scares away people who are looking at options for frame houses. The problem is solved by high-quality thermal insulation, which is a multi-layer cake. Calculation of insulation and determination of dew point should be carried out only by specialists with extensive experience, otherwise you risk getting many problems when operating the house.
The second point that scares consumers away is metal corrosion. Without going into details chemical reactions, we all know that metal rusts, including steel. The formation of rust directly affects the strength of the metal structure, in our case, the strength of the “skeleton” of the house. This problem was solved using hot galvanic treatment, thanks to which metal structures receive a protective shell 20 microns thick. At correct installation and provision reliable protection from moisture it can extend the life of metal up to 100 years!
Advantages of a metal frame – does the tree rest?
Metal frame houses are a technology that is unlikely to replace wood. The maximum that is destined for them is to develop in parallel. And this is completely justified - both metal and wooden frames there are disadvantages and advantages. Perhaps, it is in this comparison that it is best to consider metal-frame houses - why are they better and worse than wooden ones?
Metal, as mentioned above, has high thermal conductivity - wood is much better in this regard, it itself is a heat-insulating material, participating in general scheme insulation of the house. In a metal frame structure, there is no hope for the frame - all thermal protection tasks fall on the insulation and sheathing.
In full wooden house built with your own hands, life is more comfortable. The tree breathes, filling the air with aromas. However, this living material has a lot of enemies - wood-boring beetles, moisture, fungus. Of course, today there are many ways to protect yourself from all these factors, but this comes at a high cost. These enemies are not afraid of metal, except, perhaps, moisture, although the processes in both cases will occur with at different speeds in favor of metal.
True, there is another side to the issue - in modern house There are too many household appliances that affect the frame, magnetizing it. This may affect the well-being of particularly sensitive residents. The light weight of LSTK (up to 50 kg per m2) allows you to build a house with your own hands on the lightest foundation. Even on heaving soils that do not allow the use of buried foundations, you can build a large, spacious house. The metal frame is free from such disadvantages of wood as drying out and shrinkage.
The accuracy of installation of metal frame elements is always at its best. Thanks to this, time, labor and, as a result, finances are saved - construction from LSTK is cheaper. The cost of the elements themselves is also cheaper.
Disadvantages of a metal frame - forewarned is forearmed!
Oddly enough, a metal frame behaves much worse during a fire than a wooden one. Don’t think that using metal in construction will protect you any more than with wooden beam- fires in most cases start outside (arson) or inside the house (malfunction of household appliances), where there are many materials that will catch fire and burn out - furniture, things, decoration.
The main thing is that during a fire all residents can evacuate successfully - the more time they have before the house collapses, the higher the chances! So, a metal frame significantly reduces evacuation time - with high temperatures the skeleton of the house loses its rigidity, which is why the house spirals, falls, and warps. During the combustion process, wood keeps the house from collapsing much longer - the timber becomes charred, but retains its shape inside.
Another drawback that is discovered almost immediately during the design and operation process is the difficulty in installing built-in furniture and appliances. By default, the metal frame does not have a rigid, reliable base to which you could attach shelves with your own hands, or install massive cabinets and pencil cases on top. So the builders, together with the home owners, must determine in advance the places that will need to be reinforced with additional profiles and platforms made of boards.
The load-bearing capacity of LSTK significantly limits the number of storeys and the use of heavy building materials. Cannot use heavy ceramic tiles, install a fireplace on the upper floors. In the latter case, it is generally difficult to combine steel profiles With construction materials(brick, cement).
An important point is the protection of the house structure from industrial currents and atmospheric discharges. Metal profiles They are excellent conductors of electricity, and therefore can pose a danger to the inhabitants of the house. This problem is solved by a potential equalization system, the calculation and installation of which is the job of professionals.
Installation of LSTK - assembling the constructor!
Building a house from LSTK is really like assembling a construction set for children. Before installation, a project of the future house is created - all the little details are thought out in the project, right down to where the furniture will be installed and Appliances. It is very desirable that, in addition to the drawing, a 3D design of the house is also developed - this way the customer will see the house with his own eyes.
After the design documentation is completed, the drawings are transferred to the production line. Frame parts are manufactured individually, numbered, packaged and sent to the construction site. Ready-made profiles already have holes for fastenings and engineering communications. Connecting elements also come as a set.
It’s more difficult with a thermal profile - in most cases, builders are offered ready-made sizes and shapes that should be taken into account when designing. It is best not to change the existing length, cut or shorten anything. In any case, each part is packaged and labeled according to the house design drawings. Builders do not have to select parts - they only need to fasten the profiles with their own hands, according to the markings of the individual parts. This approach significantly speeds up the construction process.
Construction from LSTK is of increasing interest to modern consumers, thanks to one important advantage - the possibility of an open layout. Lightweight trusses allow you to create spans up to 14 meters long without additional elements responsible for support. The rooms inside the house are very spacious, free, and filled with air.
It should be remembered that what more room, the more difficult it will be to heat them, accordingly, the better you should insulate the walls with your own hands. Non-flammable mineral wool boards, as well as moisture-resistant polystyrene foam and ecowool, have proven themselves to be the best. Although LSTK are not very friendly with other structural materials, they are easy to finish, be it a block house that imitates a rounded log, or porcelain stoneware, which will give the building the appearance of a solid structure.
Frame construction residential buildings is a relatively new direction in the domestic construction market. The basis of any small architectural form It is assembled quickly in this way, which is why the technology is gaining popularity. If you understand the technique of connecting metal parts, you will build buildings without the help of builders. Let's figure out how to build a house frame from profile pipe with our own hands, and also discuss the advantages and disadvantages of such a design.
Frame construction of houses is a new direction in the construction market
Metal frame houses
Metal frame construction has been used in construction before. This construction method was used in the construction industrial buildings: workshops, farms, greenhouses, warehouses and hangars.
After modernization of technology, frames made of profile pipes are used for the construction of public and commercial buildings (cafes, shops, gas stations), cottages and low-rise residential buildings. Technologies are used in the reconstruction and repair of buildings - the construction of wings and attics, the addition of floors.
Advantages of frame construction
The whole world uses metal frame technology in construction. In the USA, countries Western Europe and Japan, 70% of residential buildings were built using this method. The technology has enough advantages to make it your choice when planning to build your own home.
Minimum labor costs are the main advantage of metal frame construction
- The first advantage of building a frame house from a profile pipe with your own hands is its low cost. Traditional technologies are more expensive. The price of the structure will directly depend on the materials you are going to use. The cost of the frame depends on the cross-section of the pipes, and the cross-section is selected depending on the scale of the construction. For example, if you need to assemble a staircase frame from a profile pipe (section 60x40 mm), the material will be cheaper than for the frame of a house, where the cross-section is much larger. Also one-story houses built from smaller pipe diameters than a two-story one.
- The next plus is speed. The use of profile pipes as a frame will reduce the construction time of the building several times.
- Frame technology does not provide for “wet” processes, so weather conditions do not affect construction. The exception is laying the foundation. But often the base is assembled without a foundation. For example, if you are building the frame of a greenhouse or temporary shed from a profile pipe.
- In buildings erected in accordance with frame technology, no shrinkage. During construction and operation, the building does not change its shape and does not crack. This is another plus.
The main advantage is smaller compared to traditional technologies labor costs. To build a house, you only need a couple of helpers and a month's vacation. During this time, you will have time to complete the main stages of construction, and leave interior work until the next vacation. A garage frame made from a profile pipe can be built with your own hands in a week.
Disadvantages of metal frame houses
When starting construction, weigh the pros and cons frame buildings. The technology has many advantages, but there are also disadvantages. The main disadvantage is the complex design. Calculating the load on a profile pipe in frame nodes is not as simple as it seems at first glance. If you can't do this yourself, contact a professional. It will help you calculate permissible load per meter of pipe. When choosing the cross-section and thickness of the pipe, use online calculator profile pipes.
Another disadvantage is the cost. Compared to wooden beams, metal material costs more. When purchasing pipes, people are faced with the problem of choosing: buy cheaper and save money, or choose a thicker pipe and ensure durability for many years. Here everyone judges based on their budget, but it’s better not to save money. Especially if this is a house, and not a frame for a garage made of a profile pipe.
Similar houses difficult to insulate - this is also a minus. Problems with thermal insulation arise because the metal frame allows cold to enter the building. In such rooms the air quickly cools down, even despite intense heating. Therefore, the building must be insulated efficiently: inside and out. This means you will have to spend extra money.
The metal frame facilitates the entry of cold into the building
Construction of a house from a profile pipe
To engage in such construction, you need to prepare, study all the intricacies of the design and the sequence of operations. The fact is that the ease of constructing a frame is only an apparent opinion. In reality, the design is quite complex. It all depends on your skills and abilities.
Construction of the building
A residential building is not an easy building. Here are its main elements:
- foundation;
- house frame;
- interior decoration;
- insulation;
- external finishing;
- roof frame made of profile pipe.
A foundation for a frame house is required; without it, the structure will not be durable. Its composition and construction are much easier than in traditional construction. Without a foundation, small structures (greenhouses, greenhouses) are built, which are subsequently moved around the site from place to place.
Most often used for the frame square pipes 100x100, less often - 60x60. The cross-section will depend on the dimensions of your future home. For interior decoration, use tongue and groove boards from coniferous species wood (width 40-60 mm), treated with antipyretics and antiseptics. Exterior finishing performed with siding or facade plaster. If there are sufficient funds, it is recommended natural wood.
The building must be insulated from the inside and outside
A board is laid on top of the pipe lag as a subfloor. Wood is able to retain the cold transmitted from the outside through the metal. Any profile covering is placed on top.
Extruded polystyrene foam or polystyrene foam (thickness 60-100 mm) is used as insulation. Using strips of penoizol, the frame racks are additionally insulated.
The roof is made in two ways: as a separate frame structure or as an element of the overall frame. Roof rafters They are made from profile pipes depending on the planned coating. The lighter the material and the greater the angle of the frame, the thinner the pipe.
Step-by-step instructions for building a house
The construction of any building should begin with the installation of a foundation. But before you bookmark it, study it carefully. bearing capacity soil and height groundwater on the site of the future home. For frame construction A concrete frame capital foundation is suitable. Remember: the stronger and more durable the foundation, the longer the building will stand. Correcting errors in an incorrectly laid foundation will be very expensive.
If the house is small, it is placed on a non-permanent foundation. This will make it possible to transport the house from place to place. Platforms or screw piles also used in cases where the depth of soil freezing does not allow building a house low. This technology is often used when installing a foundation under a frame for a greenhouse made from a profile pipe, when building a warm winter garden. Unlike greenhouses and greenhouses, the foundation of a residential building definitely needs to be built.
When choosing the cross-section and thickness of a pipe, use the online profile pipe calculator
The frame of the house from a profile pipe is mounted after laying the foundation. The assembly of the factory frame is carried out without the use of welding machine, everything is secured with screw connections.
There is more work to do with a homemade base for your home. To assemble a metal frame from a profile pipe, it is necessary to control the quality of the connections and the location of the elements. You can't do without a welding machine. Do not forget that the most vulnerable point in the frame is poor-quality welded joints.
Frame installation begins with installation vertical elements(columns and racks), which during assembly will be connected to horizontal parts made of thin pipes. Next, the structure is strengthened with braces. The connection of frame elements occurs according to the “bottom-up” principle.
If desired, you can assemble a hangar from a profile pipe
The roofing part is mounted in last resort. At this stage they begin interior decoration, insulation and external works. The remaining materials should not be thrown away. They will be needed for the construction of utility buildings. Greenhouses, mini-greenhouses are assembled from pipe sections, or used as arcs to support a film over plants. If the pieces are long, they will make a do-it-yourself canopy frame from a profile pipe. After the garage is built, the canopy can be easily disassembled.
If you have built a house, it means that in the future you will be able to build any other building. Now your hands are capable of anything. You can even assemble the hangar frame from a profile pipe yourself, the main thing is desire!
Construction is always associated with large expenses and a lot of problems. It seems that this will last forever. This is what clients thought before, when they were not familiar with the technique of building houses from LSTK.
Today, the technology for constructing inexpensive panel-frame houses allows you to buy or build them on a turnkey basis in a matter of days, and what is most important is that you can live in it permanently, without moving to a city apartment for the winter.
Turnkey house made of metal frame
Buy frame house- does not always mean purchasing a ready-made building. Selling a house sometimes comes down to delivery to the site. In this case, the buyer is responsible for assembly and finishing independently.
The cost of the “turnkey house” service is the price of the project plus the house kit (frame, fastening materials). Additional work(assembly, finishing inside, outside, etc.) the client chooses at his own discretion.
Which is better: buy a house kit or ready house
The company "Euro Stroy" is engaged in the sale, as well as their turnkey construction. The client is free to choose the project and materials. He decides what kind of house it will be: small one-story dacha or beautiful house 6 by 8 m with an attic. It is noteworthy that in both cases it will be an economical option for a residential building when compared with the cost of a similar structure made from other materials. By choosing the “turnkey house” option, you:
- You don’t risk making mistakes when assembling the frame;
- Don't waste time on construction;
- Completely rely on the experience of employees;
- You can control the process at all stages of construction;
- You receive a finished house on an empty plot 8-16 weeks after laying the foundation;
- Don't pay for shipping finishing materials;
- You get a guarantee.
