Technical requirements for mobile fences

The construction of a temporary fence at the construction site allows you to secure the work on it, to avoid accidents and injury to people. That is why serious requirements are imposed on this type of protective structures, reflected in the established state standard.

According to the main provisions of the document, as well as the requirements of SNiP, the fence must meet certain design requirements:

Construction site fencing must be quickly and easily disassembled, therefore standardized fittings must be used.
The sections of the structure must be made in the form of rectangles, without sharp corners, protrusions and traumatic elements. To fence a specific site on the construction site, use a 1.2 m high mesh. The permissible height of the entire fence can be at least 2 m, the section length - from 1.2 to 2 m.
The fence should be provided with gates for people working at the construction site and gates for the passage of vehicles involved in the construction.

It is also necessary that the temporary fencing of construction sites comply with the operating rules. Therefore, it should be:

Reliable and resistant to mechanical damage and atmospheric stress (gusts of wind, precipitation). Load on 1 square meter of fence - not less than 200 kg.
Manufactured from materials with a quality certificate and a long service life, not exceeding 10 years.
Installed from the sidewalk at a distance of at least 1.5 m, which provides a safe passage for pedestrians. For greater safety, the passage should be equipped with a protective canopy and railings.

Aris's mobile fences for construction sites fully comply with the established requirements of the standards. By approaching their construction responsibly, you can avoid serious consequences that pose a threat to human life or harm his health.

The construction site is a place of increased risk, because large-sized equipment is used there, heavy, sharp materials are used that can pose a danger to human health. Therefore, the area of construction, repair of the structure must be surrounded by a fence. According to the law, the presenceconstruction fencingtemporary type is required at all facilities prior to their commissioning.

What should be the temporary fence of the construction site, its functionality is regulated by two regulatory documents:

"Organization of construction production" - the norms and rules of 1985 (SNiP 0.01.01-85);
GOST 23407-78 dated 1979

According toSNiP 3.01.01-85, the construction site must be surrounded by a protective fence in order to comply with safety regulations.GOST23407-78 regulates the use of temporary barriers... The main provisions of the document:

The construction of the structure cannot be started without the installation of a temporary fence of the construction site.
The protective structure must be assembled / disassembled and made in the same style.
In the fence, wickets and gates should be provided for the passage of people working at the facility, transport;
The fence must be reliable and resistant to loads (precipitation, wind gusts, mechanical damage), withstand a weight of 200 kg / cm 2.
The fence must be built of rectangular panels 1.2-2 m long, 1.2 m high.
Materials for the construction of the fence must have a quality certificate and a service life of at least 10 years.
On the outside of the fence, a sidewalk with a width of at least 1.2 m should be arranged so that passers-by can move freely on it. It must be equipped with a protective canopy and handrail. The canopy is built at an inclination of 20 ° so that it completely blocks the sidewalk and protects people passing there from precipitation, rainwater .

Important: according to the regulationsrequirements, the structure should not have sharp, traumatic parts.

Varieties of construction site fences

By design, fences around construction sites are:

signaling - visually indicate the boundaries of the high-risk zone. They are represented by a special tape fixed between pins driven into the ground;
protective - to avoid possible injury. These include the façade mesh that catches everything that falls from the scaffolding;
security - the purpose of the installation of which is to prevent unauthorized persons from entering the construction site. They are fences made of various materials.

By the complexity of the construction of fencing construction sites can be:

standard - simple structures in the form of a wall;
with additional details - fences equipped with canopies, sidewalks, struts, railings.

Advice: if the construction is designed for a short time, the best option would be to install a standard fence, which will be inexpensive.

Structurally, building fences are distinguished:

rack-mount - is a rack, fixed in the slabs of the roadway;
panel - fences surrounding the construction site with a solid or sparse (mesh) wall;
combined - are a combination of the two previous varieties.

Materials used for the manufacture of protective fences

Temporary construction site fences consist of:

supports;
frame;
filling.

They can be made from:

plastic;
metal;
wood;
slate.

Note: the material for the construction of the protective fence must be of high quality and comply with the established standards.

Plastic

Thanks to modern technologies, the list of building materials has expanded. It includes plastic structures, from which you can also build a temporary fence for a construction site.

A plastic fence can be represented as a polymer mesh stretched between the poles. Thanks to its bright colors, it is noticeable on the ground, which contributes to the implementation of its signaling function.

Advice: steel wire will strengthen such a fence, threaded along its edges.

A popular temporary fencing is the design of their plastic blocks, with polycarbonate sheets fixed at the top edges. Such a fence consists of type-setting sections, so its length can be changed.

Plastic fencing has the following advantages:

resistance to the influence of environmental factors. Plastic tolerates temperature changes well, it is not afraid of corrosion, high humidity;
ease of installation. The material is lightweight, so products made from it can be transferred and installed by one person;
ease of care. Plastics are given a certain color at the factory - products from it do not need additional painting, they are easy to wash;
affordable price. Artificial material is cheaper than natural wood or metal.

Note: In accordance with current regulations, plastic fencing can be used. However, it cannot be used for large-scale construction, requiring the construction of continuous protective fences.

Tree

Wood attracts with its naturalness and affordable cost, but a building fence is erected from it only if the material is planned to be used in the future.

The installation of a wooden fence is carried out quickly, but the structure must be additionally treated with antiseptic agents that will protect it from fire and decay. The cost of such a fence depends on the type of raw material, prices for impregnating compounds.

Metal

The simplest and most affordable type of temporary construction metal fencing is a chain-link mesh. It is easy to install, carry, and can be used many times. Installation of the mesh is carried out on a frame made of professional pipes and equal angles. But this material, like plastic, is not used in large-scale construction.

Inventory building fences are a more popular option. They are sections made of profiled mesh, allowing you to quickly build a temporary fence of arbitrary shape. Supports of these structures can be metal or concrete, which allows you to create enclosing structures of different stability.

The most expensive option for metal fencing for construction sites is the use of corrugated board. These are durable, but at the same time, thin steel sheets with a protective polymer coating.

A fence made of profiled sheet consists of supports and a frame, sheathed with metal shields. It has high strength, durability, resistance to moisture, unpretentious maintenance, easy to install.

Slate

A decade ago, temporary slate fences were common. But in modern conditions, the material has lost its position in the construction market. It attracts with its affordable cost, easy installation, but is very fragile, prone to the formation of fungus, and has an unattractive appearance.

The choice of material for the construction of a temporary fence is carried out based on the specific situation. For large-scale construction, you will need a reliable protective and security fence (for example, from corrugated board). For small jobs, a plastic or mesh fence will suffice.

On a note: if the construction work will be short-lived, you can not spend money on buying a fence, but rent it.

The device of a temporary fence allows you to secure the construction, avoid injury to people, accidents. It is necessary to approach the construction of a protective fence with all responsibility, to act in accordance with the established norms and rules, since neglect of them can threaten with serious consequences.

Construction fences are protective and warning structures that designate the perimeter of the area for performing construction and repair work, and do not allow outsiders to enter it. According to the current regulations, the enclosing structures are installed during the work, regardless of the duration.

Even short-term repairs require an adequate barrier. And it is extremely rare on a construction site that stationary deaf structures made of profiled sheet or timber are needed. The orange plastic fencing mesh solves the challenges posed to a temporary fence.

Noticeable obstruction. The bright mesh is visible from afar and attracts attention, it is noticeable even at night.
A neat look. A canvas with square, rectangular cells in a bright or muted color looks aesthetically pleasing. Visual permeability meets the requirements of urban planning departments in Russian cities.
Cheapness. Construction site fencing made of plastic mesh is cheaper than metal or timber.

It is easier to install, quick to assemble with plastic posts and can be reused.

Emergency fence - characteristics

The grid has the following features.

Made of polyethylene or polypropylene. Polyethylene is resistant to low temperatures, can be used in winter. Polypropylene is stronger, looks like a lattice and does not sag. Resistant to wind gusts, mechanical stress, durable.
Resistant to external influences. Frost resistance of the mesh for temporary fencing is -40 ... -60оС. Light stabilizers in the polymer structure give resistance to ultraviolet light. Thanks to light stabilizers, the plastic retains its strength and elasticity in the sun.
Long lasting. The service life is five years. During this period, the grill can be applied intermittently or continuously.
Not afraid of moisture. Plastic, unlike metal and wood, is not susceptible to rainfall. Corrosion and decay are excluded, painting and other maintenance of the fence is not required.

These features are possessed by gratings made of polyethylene and polypropylene in red, orange, black, gray and other colors.

Application of emergency fences

Use lightweight, inexpensive structures to install booms:

building spots;
section of excavation of a pit, communications;
places of landscaping and improvement;
road repair and construction site;
object during the repair of the facade, roof.

For installation, choose plastic supports, posts or metal posts for quick fixing to the ground.

According to the method of application, such structures are divided into two main categories:

Stationary
Lightweight (modular)

In the first case, serious preparation will be required related to the arrangement of the foundation, such work makes sense for capital construction, calculated for more than one month or even a year. Actually, such fences themselves are, in fact, separate buildings. The profitability of their installation is not always achieved, therefore fences of a different plan are more widespread.

Portable, usually modular, can be found almost everywhere: during road repair, building reconstruction, installation of lighting masts, laying of communications. Also, such products are widely used during large-scale events, sports competitions that attract significant masses of people. And one more application - as inexpensive fences, summer cottages or around places of temporary storage of materials.

There are several separate types of barrage structures:

Solid, from panels
Rack, lattice
Combined, combining both of the previous types

Solid temporary construction site fences, as such, usually have gaps between panels. This is due to the need to avoid wind loads, because the foundation, or too massive supports under them are not provided. Is that small concrete blocks, which are moved by compact equipment.

Construction fencing made of lattices, as a rule, welded, is the most frequent visitor on the city streets. They are very easy to deploy on the spot, they can be transported by small transport, in case of a fall, which sometimes happens, they do not injure a person.

Sometimes a combination of those and others is required, for example, when one work site in a fragment goes to a pedestrian path.

By the principle of work, they are divided into:

Signal
Protective

Accordingly, in the first case, the color is brighter, more contrasting, visible from afar. However, the second type should also be noticeable. Lighting can be used as an adjunct.

Legal requirements:

The list looks like this:

Safety during operation for pedestrians and vehicles Ease of installation due to well-calculated dimensions
Suitable for all climates
Attractive appearance and durability
The absence of any buried supports and foundations

The requirements are strictly regulated and spelled out in the relevant regulations, both federal and regional. For the capital, uniform standards have been developed according to which our plant produces such products. They were approved by the decree of the Moscow Government No. 299-PP dated 05.19.2015. (with changes from 2018), in total there are 25 positions in the list:

Signal: 1 AP, 1 AN (1), 1 AN (2), 1 PS, 1 BN (1), 1 BN (2), 1 BN (3), 1 VP, 1 VN (1), 1 VN ( 2);

Protective: 2 AP, 2 AN (1), 2 AN (2), 2 BN (1), 2 BN (2), 2 BP, 2 VP;

Security: 3 AP, 3 AN, 3 BP, 3 BN (1), 3 BN (2), 3 BN (3), 3 VP, 3 GP.

Production

In urban conditions, a strict geometry of a construction site is almost never encountered. This is unrealistic, because the layout of streets, parks, paths has evolved over the years, and recently there has been a tendency towards interesting, design solutions. Therefore, it is not easy to protect the selected area.

Therefore, our partner plant produces and offers consumers a modular plan. They can be installed anywhere, come in a variety of lengths, blend perfectly with each other, and ultimately form a single, reliable barrier.

Some products undergo mandatory anti-corrosion treatment, they are completely safe during operation, and are presented on our website. You can choose for yourself the necessary products, connecting elements from the range of finished products. If required, we are ready to make any light fences to order according to your drawings (for large volumes). Production capacity and the availability of modern equipment allow you to complete the task on time, with delivery to the specified location.
