The exceptional properties of the metal profile pipe make it possible to use it in many areas of industry, in particular, it concerns the construction sector. Lightweight metal structures are installed as frames in industrial facilities, in public buildings, shopping centers and exhibition pavilions. Columns and trusses, sheds and fences, benches and gazebos, stairs and bridges are made of pipes. Today, hollow profile products are often used in the residential sector for the construction of attics, various kinds of superstructures, outbuildings and even low-rise buildings.

Methods for manufacturing a profile pipe, its advantages and types

Manufacturers produce pipes profile section seamless and electrowelded. In the first case, round or faceted metal blanks are subjected to preliminary deformation - pressing or piercing. In the second case, a strip of steel sheet (strip) is passed through the roll forming equipment, and the resulting closing seam is welded. Received different ways billets are finally formed on rolling mills hot, warm or cold, as a result of which the required profiles are obtained. In the future, heat treatment of products is carried out, which increases their technical and operational characteristics.

In construction, as a rule, metal profile pipes of square and rectangular cross-section are used. Due to their shape and manufacturing technology, they are obtained:

• lightweight - light weight makes it easier to assemble structures;
• reliable - stiffening ribs give additional strength;
• convenient in transportation and storage - less space is used compared to round products, and no special fastening is required;
• easy to install - docking with flat surfaces is not difficult.

Metal structures made of shaped pipes allow:

• reduce the cost of construction by reducing the construction time;
• to carry out work in cold period time;
• to ease the load on the foundation;
• not to be afraid of subsidence of the building frame;
• perform complex structural elements.

The disadvantage of using a profile pipe for any metal structure can be an incorrect calculation of the loads. Therefore, specialists should be involved in the design of trusses, columns, vaults and other elements of the frame. Otherwise, the building during operation may simply "fold".

It should be noted that thick-walled pipes, suitable for the manufacture of load-bearing elements of frame buildings, have a high cost. But the absence of the need for a massive foundation and the speed of the construction of the object in many cases are relegated to the background.

In addition to the size and shape of the section of the profile pipe, metal products differ in the type of material used. They can be made of steel, aluminum and its alloys, with a zinc-plated or subsequently painted surface. Aluminum pipes are used for fencing, facade systems, internal elements of the interior and "light" buildings, and more durable structures, such as trusses and columns, are made of steel analogs. Galvanized pipes are installed where aesthetics and reliability are required - in the construction of "open" frames, in-house buildings, sports complexes, as well as in the manufacture of fence sections.

The scope of the profile pipe is so wide that it is difficult to overestimate it. But in heating and plumbing systems it is not used. There are more suitable options for them.

Rafter metal structures

Farms from shaped pipes have a significantly lower weight than those made of corners, channels, or T-bars. It is quite possible to assemble them on your own directly on the construction site, but only with the appropriate experience.

With the wrong technology, a curved roof may well turn out, which will not look aesthetically pleasing. And after a while, if not immediately, it will surely collapse. It should also be remembered that metal trusses made of shaped pipes should be laid if, as roofing lightweight modern materials will be used.

Depending on the span and shape of the roof, the trusses perform:

• triangular;
• broken;
• trapezoidal;
• with parallel belts;
• single-slope;
• arched;
• asymmetrical.

Almost any trusses can be recreated from shaped pipes - with different forms kerchiefs, types of braces and racks, as well as support options. The assembly is carried out by welding using additional reinforcing elements at the docking joints. In addition, braces and spacers may be present in the structure of the truss, and bolts and rivets as fasteners.

The shape and dimensions of the metal structure, the location of pipes and the number of additional elements are determined by calculations that take into account the transfer and redistribution of possible permanent and variable loads.

Correctly designed and assembled trusses from shaped pipes are allowed to be used in critical areas of structures. They can serve without problems for years, but the high cost does not yet add to their popularity among private developers. Most often, owners use shaped pipes for the installation of small buildings in their local areas.

Frame houses

In almost every locality today you can find prefabricated frame structures in the form shopping centers and cafes, showrooms and warehouse hangars, bus stops, covered parking lots and gas stations. Previously production workshops built from massive metal structures, and now channels and corners have been replaced with lightweight shaped pipes. New technologies have pushed the boundaries frame construction and ensured the rapidity of the emergence of new buildings.

V European countries, Japan and USA low-rise residential buildings with the use of structures from shaped pipes, they build quite intensively, but for our fellow citizens, cheaper ones remain priority wooden frames... But if we compare the "western" buildings with buildings erected from traditional materials(brick, concrete, solid logs), then in terms of financial and labor costs, the latter will cost more than metal-frame houses.

In fact, the cost of a structure made of shaped pipes directly depends on the materials used. In particular, the size of the section and wall thickness of pipes, methods of insulation, as well as options for interior and exterior decoration play an important role.

General principles

Vertical steel structures are installed on the foundation. It is laid below the level of soil freezing, but it is performed in a lighter version than would be required during construction load-bearing walls from traditional materials. It is allowed not to arrange a capital foundation only for temporary buildings, which can sometimes be moved from place to place or disassembled. This applies, for example, to greenhouses, seasonal sheds or greenhouses.

The frame is mounted in stages, connecting the profile pipes to each other using:

• welding;
• threaded connections;
• riveting.

Factory metal structures are assembled faster and easier, as they are completed with special fasteners, and the pipes have clear fixed dimensions. Welded joints require constant monitoring of the correct location of adjacent elements. In this case, the construction of the frame needs a more careful and accurate approach. Installation work produce from the bottom up. Stability of vertical elements is ensured by horizontal strapping and braces made of profile pipes of a smaller section.

The roofing part of the structure is erected in two ways, depending on its design features... In the first case, it will be one of the elements of the general framework, and in the second - a separate structure consisting of several trusses installed on supporting posts, columns or beams.

It should be noted that the more the slope of the slopes will be chosen and the easier roofing materials, the thinner the profile pipes will be required for the installation of the roof.

The next stage in the construction of a residential building is work on the insulation of the enclosing structures. For these purposes, experts recommend using extruded foam and advise not to forget about additional insulation of metal structures so that they do not turn into a kind of cold bridges.

Simple and popular metal structures

On the territory of the garden plots, the owners often set up sheds for storing equipment and summer kitchens, souls and outdoor toilets using metal pipes profile section. Such structures are quickly erected and, if necessary, dismantled. But there are more capital buildings serving for years.

Fence from shaped pipes

Owners of private houses prefer solid fences that hide the site from prying eyes. But the territories of public institutions, parks and gardens are surrounded by fences made of shaped pipes, eliminating shading and providing an excellent overview. Such fences look more elegant than concrete and brick ones, and are built faster and easier.

Metal structures of fences can consist of straight or bent profiles, have simple forms or combined with openwork forging elements.

The most popular option is considered to be the enclosing structure, consisting of hollow square pillars, a pair of horizontal and many vertical rectangular shaped pipes of small size. As with assembling a truss, the elements are welded together, but they can also be fixed using couplings or brackets.

The work is carried out in stages.

1. On a stretched level, at a distance of about three meters from each other, the locations for the installation of the pillars are outlined.
2. Pipes are dug in and concreted, or driven in.
3. The lower and upper crossbars are welded onto the pillars.
4. On horizontal elements, vertical profiles are fixed equidistantly, having the same or different length.

Metal structures are also hung on a frame made of shaped pipes, which are ready-made intake sections, manufactured in an industrial environment or independently. In this case, the same profiles, mesh or reinforcing bars can be used as filling. And sheets of corrugated board will help to hide the site from curious passers-by.

Pipes of rectangular cross-section are often installed on the canvases of wickets or gates, even with a continuous fence of the site. The advantage of this solution is the reduction of the load on support pillars, which makes it possible to expand the passage. In addition, the hosts will always be able to see the visitors in advance and communicate with them without opening the gate or letting in unexpected guests, which in some cases is very important.

Visors and awnings

Lightweight metal structures designed for the construction of free-standing awnings, canopies over entrances, as well as roofs for gazebos, terraces and garages are also made of shaped pipes. In their shape, they resemble metal trusses, but smaller in size and excellent in filling. They don't get stronger large quantity struts and braces, and in some cases, when the structure consists of separately located pipes, they do not have them at all.

For arched canopies metal profiles bend, and for pitched canopies they are welded with vertical or horizontal elements at the required slope in accordance with the drawings. On the ready-made structures lay lightweight roofing materials. For this, tents are often used or transparent sheets polycarbonate.

Metal structures are now very widespread. If previously they were used in construction only industrial enterprises then now these building construction took strong positions in the construction of new residential buildings and structures.

Today, the issue of lightening (reducing the mass) of metal structures is already acute. Moving in this direction, the designers reduce the metal consumption of the building and “kill” two “birds with one stone”:

• the cost of the structure under construction is reduced;
• the mass of the building is reduced. This leads to a decrease in the volume of the foundation and, ultimately, again to saving the budget of the entire construction.

Frame technology of building construction

Everywhere the frames of buildings and structures under construction frame technology, are made of cold-formed profiles (Σ-shaped or C-shaped) and (or) welded to each other I-beams of variable and constant cross-section.

Fences are made of sheet (light) metal, which, to give it rigidity, is subject to deformation:

• profiled sheet;
• profiled sheet with foil mineral wool insulation;
• sandwich panels, etc.

This is described in detail in the article "Design of steel structures" and on our website.

Thus, buildings and structures built using frame technology are lightweight. In addition, they have a number of undeniable advantages:

• it is possible (thanks to components at a specialized enterprise and the creation of a foundation at a construction site) to build them in a short time;
• they are highly maintainable. If any part or unit is out of order, it is possible to dismantle them relatively easily (it is not required to disassemble the whole house - it is only necessary, as in any mechanism, to "unscrew" threaded connection of the unit to be replaced) and replace with exactly the same factory-made one;
• to erect a building using this technology requires a very modest budget and more.

Today we'll talk about other ways to give rigidity sheet metal, which is used in the production of metal structures.

Methods for stiffening sheet metal

One of the new, but already popular, methods is the creation of lightweight metal structures. A new competitive technology in construction, which has this name, consists in the use of a variety of progressive spatial forms during metal deformation:

• volumetric faces;
• geometric figures:
  • rectangular indentations
  • rounded trays, etc.

This appearance is achieved by cold bending (cold deformation) of special blanks. In order for the metal elements to have mechanical rigidity, and the nodes to have high strength, their tops are connected.

As a result of the connection, a knitting is created, which forms a system of rigid rods. It should be borne in mind that what harder form, the higher the strength and bearing capacity of the prefabricated steel structure.

From metal products with such a design, you can collect:

• frameless construction objects;
• base for wall cladding, facades, etc.

There are several special design techniques for increasing mechanical strength every single detail.

Methods for increasing the mechanical strength of lightweight metal structures

There are several structural and technological methods (they are incorporated into the design of a part at the stage of its development), designed to increase the mechanical rigidity and strength of a lightweight metal structure:

• longitudinal profiling is carried out. It consists in creating horizontal sections of the surface in the direction of rolling the steel sheet;
• corrugation of edges. Corrugations are created, the edges of which prevent the deformation of the part during operation;
• stamping. The punching method creates a variety of volumetric bulges (convex or recessed), cut ribs, etc.

Lightweight metal structures are widely used in the construction of pre-fabricated buildings and structures, and their use allows you to reduce material costs and speed up the process of building objects. Manufacturers suggest using hot-rolled or cold-rolled metal profiles, which are produced by stamping. Modern technology LSTK is used for fast construction of buildings, which are characterized by a wide range of applications, long service life and increased strength.
The main advantages of using lightweight metal structures for the construction of pre-fabricated structures include:

high quality metal structures at an affordable cost;
durability and reliability;
strength and durability;
versatility and mobility;
resistance to corrosion processes, mold and fungi due to the presence of a special protective anti-corrosion coating;
wide range of applications in industry, agriculture and building houses.

Construction and installation work is carried out in any weather and at any time of the year due to the absence of a "wet" finish, and all structural elements are assembled quickly and easily using anchor bolts and self-tapping screws.

Features of production and construction.

LSTK technology involves the use of light, durable thin-walled metal structures, each part is marked at the factory, therefore, construction site the construction of structures from lightweight metal structures is carried out in as soon as possible professional team of workers.

When developing a project for a building made of metal structures, the target application, the customer's needs, the expected operational load and the need for insulation are taken into account. Modern high-quality materials are used as insulation. thermal insulation materials, namely foam, extruded polystyrene foam, mineral and basalt wool, fiberglass.

Due to the compactness of all metal structures, they are quickly and conveniently delivered to the construction site, which reduces the cost of their transportation. The construction of buildings from lightweight metal structures does not require the arrangement of expensive monolithic foundation as in capital construction, therefore, the total production costs of construction are reduced.

Scope of application of lightweight metal structures.

Warehouses and hangars, which are used in industry and agriculture, are built from lightweight metal structures. These are all kinds of main and auxiliary industrial workshops, utility rooms for storage Vehicle, equipment, special equipment and inventory.

In agriculture, such buildings are intended for storing vegetables and grain crops, and insulated premises are used for breeding and raising poultry and animals. When developing a project, the creation of certain climatic conditions, laying engineering communications, ventilation system and air conditioning, artificial lighting and the need for insulation.

Buildings made of lightweight metal structures are distinguished by their strength and lightness, fast erection of the frame, walls and roof, therefore, today they are being built country houses, summer cottages and cottages. This is a profitable investment, since the cost of the work is significantly lower compared to capital construction.
Technology for the construction of objects from lightweight metal structures

For the construction of prefabricated buildings, the innovative LSTK technology is used, which consists in the use of durable lightweight profiles, which can be load-bearing, guide and hat. Of them, not only the frame of the structure itself is erected, but also walls, roof ceilings, and a shallow tape or pile is used as a foundation.

The choice of foundation depends on the type of soil, the depth groundwater and climatic conditions of the area. Using this technology, you can build objects of any shape and complexity: straight-walled, arched, polygonal and hipped roof. They differ from each other in design and shape, but they all have high strength, versatility, durability and reliability.

For effective protection against corrosion, the surface of metal structures is coated with protective anti-corrosion compounds ( polymeric materials, enamel or primer). The construction of structures from lightweight metal structures fully complies with the requirements fire safety, state standards and environmental friendliness.

Strengthening Structures it is necessary in the case when the building load began to exceed the maximum allowable, laid down in the project. This may be the result of the implementation of work on the construction of additional floors, or errors in an unfairly drawn up project, violation of operating rules, changes in the functionality of the building, corrosion processes.
But more often the strengthening of the skeleton or parts of the structure becomes necessary due to its wear.

Strengthening Building Structures

Strengthening the structure of a building involves carrying out work aimed at maintaining the ability of the building to withstand heavy loads and increasing its rigidity. The procedures for strengthening a structure involve the application of various methods.

The main ones are amplification bearing capacity, restoration of the building structure, its unloading, as well as strengthening individual elements... Depending on the material, a distinction is made between:

• strengthening of metal structures,
• gain reinforced concrete structures,
• gain wooden structures etc.

Let's take a closer look at some of them.

Reinforcement of Reinforced Concrete Structures.

To strengthen reinforced concrete structures, work is carried out with the foundation, floor elements, crossbars, columns. Trusses and beams usually need to be replaced.

The strengthening procedures are preceded by a preparatory stage. By creating additional supporting conditions, the load of the bearing parts is more evenly distributed and transferred to the new elements. It is important to understand that reinforcing the structure of a building is associated with risk, as it is impossible to accurately assess the original data of old structures.

Strengthening Metal Structures

To strengthen metal structures, either increase the cross-sectional area for which the load is applied, or increase its rigidity. Before starting all procedures, it is necessary to familiarize yourself with the design documentation and materials for the operation of the building. Further, assessment procedures and field studies are carried out.
