Varieties of technologies for the construction of frame houses from a metal profile. Metal frame houses: disadvantages, advantages and reviews

The construction of a frame house has several advantages. You can build such a house quickly, economically and efficiently. Metal frames are lighter and stronger, have increased fire resistance. Insulated houses based on metal frames have high energy-saving properties. The installation of a metal frame has its own nuances that must be taken into account during construction.

Advantages of a metal frame house

Metal frames have some undeniable advantages over wooden ones. One of its main advantages is the relatively low price. Typically, the price of turnkey frames depends on the choice of material from which they are going to be made, on the fastening method used, and on the cost of installation work.

Metal carcass

Metal frames are made of steel, which is reflected in their second name. These products are also called LSTK, which stands for light steel thin-walled structures.

one more indisputable advantage such a frame is its strength and lightness. These frames weigh less than others, but are much stronger. They are able to withstand tall and heavy buildings.

Metal frames are manufactured at the factory with a preliminary drafting of a project in which the dimensions of all elements are fixed. These elements can be placed concealed wiring. Since they are made of steel, they have an increased resistance to fire and are not subject to corrosion.

Main properties of light steel thin-walled structures

Features of assembling houses from a metal profile

The LSTK technology was developed in the last century. Metal frames are built from a profile with slots. This allows you to avoid the occurrence of cold bridges inside. The problems of thermal insulation and sound insulation can be solved with the help of modern heaters.

In structures with a metal frame, special attention is paid to the installation of a layer for steam, hydro and thermal insulation. This is due to the fact that in them the dew point is located inside the house. For this reason, it is also necessary to correctly make wind protection. Moreover, it is necessary to make sure that there is a ventilation system between the outer waterproofing layer and the insulation. It can be made by hand. This will facilitate the rapid removal of moisture. In houses of this type, it is necessary to organize competent electrical protection.

Previously, the use of metal as a frame was questionable. This was due to its increased thermal conductivity. This problem was solved by using galvanized metal profiles with perforations. The holes are filled with insulation, which reduces the level of thermal conductivity. This indicator is also influenced by the wall thickness. Therefore, the reviews of such houses relate to insulation issues.

One of the challenges faced in the construction similar houses, is their increased electrical conductivity. However, it is solved by competent grounding.

How to choose a foundation for a metal frame house. Will it be different from a wooden frame?

For a metal frame house, a foundation on screw piles is suitable

Unlike the foundation for a house with a wooden frame, when building LSTK, there is no need to build a massive base. Such a house is quite light and does not need a massive foundation. The developer does not have to deal with volumetric earthworks, you will also not need to build formwork, two meters high, to mount a solid waterproofing. They can be built on any type of soil. The construction of a strip foundation is not required.

After analyzing the properties of the soil, you can choose the type of foundation for your light house. An excellent option can be columnar foundations, screw piles.

Metal frame mounting technology

When mounting the frame, it is necessary to create spatial blocks, flat frames and strengthen them as much as possible

In the process of mounting a metal frame, it is necessary to take into account the properties of the material. Care must be taken not to damage it during transport. During installation, you need to strive to create spatial blocks, flat frames and strengthen them as much as possible.

During the preparation of the foundation, transverse risks are applied to it, which must correspond to the axes of the future frame, the supporting surfaces and the location of the anchor bolts. With the help of anchors, it will be possible to correct installation inaccuracies.

Connections of metal beams can be not only bolted, but also welded. The frame itself consists of a lower and upper harness. There is also a connection between them. It is necessary to design in advance door and window openings, metal crate.

1. The profile is cut to the desired size;
2. If necessary, bends at a pre-calculated angle;
3. The resulting parts are welded or bolted according to the scheme.

There are three options for enclosing structures:

1. Sheet assembly;
2. Cassette profile;
3. The use of sandwich panels manufactured at the factory.

The choice of materials for the installation of these enclosing structures is at the choice of customers. See photo views.

Exterior decoration of the house

Is one of milestones. The type of finish is determined by the customer and can be made using various materials:

1. If you want to do a budget option finishes, it makes sense to use vinyl siding, block house, mount a ventilated facade and other hinged structures;
2. If you make the finish with plaster, then the house will give the impression of a Mediterranean cottage;
3. Affordable prices and ease of installation attract those who use various panels having the appearance of natural materials;
4. Finishing with tiles, natural and artificial stones looks very impressive. The house becomes like a solid and expensive one, but at the same time retains all the advantages of a metal frame structure.

Low-rise metal frame houses are popular all over the world. Statistically, housing construction on a metal profile frame occupies 80% of all buildings. The main consumer regions of this technology are Scandinavia, USA, 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 terms of construction of buildings;
• inertness to weather and climatic conditions;
• low cost;
• resistance to heat loss;
• high fire safety;
• seismic resistance;
• environmental friendliness;
• freedom in the choice of architectural solutions;
• non-shrink technology.

The iron frame, its elements are light steel thin-walled structures, consists of galvanized profiles and thermal profiles, fastening tapes and plates for assembling the frame, different kind corners. They are not subject to decay, withstand temperature extremes, 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 build a building on a LSTK frame within a month. The details of the base of the building are lightweight, which eliminates the use of hoists and cranes. The fastening of the 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 housing construction not tied to the climate in the region. The metal frame for the house can be assembled in any climate zone, the main condition for weather conditions– comfort for workers performing the installation.

The emergence and development of technology for the construction of residential buildings on metal frames is caused by the need fast erection low-rise buildings from materials cheaper than wood and the ability to establish industrial production frame details.

The final cost of a frame house from metal profile and sandwich panels is much lower than the construction of bricks, gas blocks, wood and ceramic blocks.

High thermal insulation characteristics structures are provided with high-quality insulation. Heating such buildings is much easier and more economical. Heat transfer resistance frame wall 25 cm thick is equal to masonry 1.5 m thick.

Sandwich panels used in frame construction use mineral wool insulation. Its temperature range is -60…+400ᵒС. Characteristics wall panels make the house resistant to acids and other aggressive environments, temperature extremes, fire. The material from which they are made does not accumulate moisture, is resistant to damage by rodents and microorganisms.

Mineral wool insulation is natural and environmentally friendly. Frame elements from LSTC can be reused. This property is highly valued by mining companies that build shift camps. So the ecology of the regions is less damaged.

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 installing intermediate supports can reach 14-24 m.

Disadvantages of a metal profile frame

The base of metal parts has several disadvantages.

1. In case of fire, the base of galvanized iron loses its rigidity, the building turns into a spiral, it falls off, warps. This feature reduces occupant evacuation time. wooden beam, in contrast to iron, charred under the influence of fire, but keeps its shape.
2. The complexity of the installation of built-in furniture and household appliances. To solve the problem at the design stage, houses are determined with their installation sites, which are reinforced with additional profiles and wood panels.
3. The limited number of storeys of the house and the impossibility of using heavy building materials.
4. High conductivity electric current metal frame. Protection against this problem is the potential balancing system.

Fabrication and installation of a frame from LSTK

The skeleton of the house is made of C- and U-profile. They are connected with self-tapping screws. Step between racks 600-1000 mm. It takes into account the dimensions of the insulation panels and allows you to conveniently mount other Decoration Materials.

If the house is being built according to an individual project, then after its development and coordination 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. At the end of the registration process project documentation the drawings are transferred to the factory that produces the metal frame parts.

On the production line Each item is made separately, numbered and packaged. Finished parts are equipped with holes for fasteners and under engineering Communication. For mounting the skeleton of the house, connecting elements are included in the kit for the base parts.

Buildings on individual projects are much more expensive than houses made according to standard projects. To reduce the cost of housing construction, you can use a standard project with a frame made of a thermal profile or light steel thin-walled structures according to Canadian technology. Its difference from other technologies for the rapid construction of buildings is the LSTK frame and special SIP panels with special thermal insulation characteristics.

In the case of housing construction standard project the customer receives finished frame certain size and shape. Base parts are labeled and packaged according to house drawings.

As a heater, except mineral wool, can be used:

• basalt slabs;
• expanded polystyrene;
• ecowool.

For finishing the exterior walls of the house, brick, porcelain stoneware are used. Often, hinged ventilated facades are used as finishing of the facades of frame buildings. various types. Finishing materials such as siding and block house are becoming increasingly popular. Plastering and painting of 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, a specification of all elements.

Build inexpensive and reliable housing in a short time will help metal carcass for home. These structures were mainly used for the construction of industrial and commercial buildings, due to the high thermal conductivity of the material. With the advent of thermal profiles and different type Insulators metal frame houses were a significant competitor to wooden ones.

A metal frame house can be built both in classical and modern or high-tech style.

Features of frame houses from a metal profile

The house from the profile consists entirely of metal structures. They are the basis of walls, floors and roofs. The thickness of the profiles used depends on the bearing loads.

Features of such buildings:

due to light frame the weight of the whole house is reduced;

a house made of a straight steel profile is built quickly and does not require the use of many building tools.

Despite the emergence of new technologies in construction, a metal house requires additional thermal insulation, since this material has a high thermal conductivity. The choice of this or that insulation depends on the climatic conditions in which the house will be located.

The metal used in the construction of such houses is durable, does not rot and burn, does not require additional processing. The material can be completely recycled without harming the environment.

Construction work is carried out in any season, regardless of the weather. The steel frame is suitable for the construction of low one-, two-, three-, and four-story buildings.

Advantages and disadvantages of metal profile houses

The technology of building frame houses made of metal is becoming more and more popular. This is facilitated by a number of advantages of this material.

A metal frame house is much lighter than a wooden and brick house. When performing work, it is used less material, which makes it possible to build a lighter and not so solid foundation. Mostly use its tape and pile types. Installation work carried out faster. Their cost is much lower than when working with wooden base Houses.

Since a metal profile house is much colder than a wooden or brick house, the technology of light thin-walled steel structures is used in its construction. In this case, the profile is protected from heat transfer by additional heaters that fill the entire space between the frame racks. As thermal insulation materials use mineral wool, polystyrene foam, ecowool, expanded polystyrene. These materials have high cost and also have good soundproofing properties.

Warming plays important part to create a warm and environmentally friendly home

Having correctly made the so-called “pie” for insulating the walls of the house, in compliance with the technology of protection from the wind from the outside and from the steam inside, you can achieve maximum insulation of the house.

A frame house made of metal profiles, despite the lightness of steel structures, is quite durable. Its service life reaches 100 years. Reliability is achieved by using galvanized profiles equipped with stiffeners. The coating of the material protects it from corrosion. The frame of a metal house does not shrink over time, does not crack, has good fire safety and is not affected by pests.

To reduce the electrical conductivity of the material, metal-frame buildings are equipped with proper grounding. To finish the house outside and inside, materials are used that are in themselves dielectrics. The complex of these works provides complete insulation of metal parts.

An important advantage of a steel frame is its ability to withstand roofing materials having a large weight.

The disadvantage of using a metal frame is its rapid destruction during a fire. From high temperature, the metal loses its rigidity and deforms. At the same time, the house is destroyed much faster than the wooden one.

In such a house it is difficult to install built-in furniture and household appliances. For the installation of massive cabinets and other devices, it is necessary to additionally strengthen the place for installation with profiles. The steel profile is difficult to combine with materials such as cement or brick. This is especially inconvenient when building a fireplace or other structural elements Houses.

About the features of building a house from LSTK in detail in the following video:

On our website you can get acquainted with the most construction companies presented at the exhibition of houses "Low-rise Country".

Types of steel profiles

For the manufacture of elements of light thin-walled steel structures, durable structural steel is used. The product itself is made using the cold stamping method. For corrosion protection on a metal sheet apply zinc coating.

Metal structures are also made from hot-dip galvanized sheets. They are used less often because of their high cost but much more durable in operation.

For the production of a profile, a sheet of steel is taken from 0.7 to 2 mm. The choice of thickness is influenced by the required load bearing capacity construction element.

The following types of profiles are used:

guides,

rack,

Special beams are also used to cover the floor and shelf. The truss system of the building consists of the same elements. Connect all elements of the metal frame structure with bolts, rivets, self-tapping screws. In some cases, contact welding is used.

Stages of building a house from a metal profile

The stages of construction of a metal frame house are the construction of:

foundation;

• structural insulation;

  home decoration.

Foundation

The frame of metal profiles is lightweight and does not require the construction of a solid foundation. Before choosing the type of foundation, you should study the nature of the soil on the construction site.

For such a house, shallowly recessed is quite suitable. strip foundation. It may be of small width, since the load is from lightweight steel structure will be small. The base is made as a rigid horizontal frame, which allows redistributing the load in case of deformation of the base.

Using column foundation The frame is made of rigidly interconnected beams mounted on supports.

Pile-screw foundation with a strapping of timber 200x200 is ready for fastening the metal frame

For the foundation, brick, reinforced concrete and monolithic blocks. The device is fine buried foundations allows you to save concrete consumption and reduce labor costs, which in turn reduces the cost of the house.

On our website you can find contacts of construction companies that offer. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

Frame assembly and roof installation

The turnkey metal frame house consists of required elements which affect the reliability of its operation. These include:

horizontal frame;

metal columns used to connect the frame to the foundation;

vertical columns;

roof trusses;

• purlins for attaching wall panels.

The rigidity and stability of the frame in all three directions is created in compliance with the rules for installing the main structural elements: frames, trusses and columns. This is achieved in compliance with the rules of spatial geometry. All products are manufactured with a high degree of precision.

To speed up the installation process, each product is marked accordingly. Structural elements the future house is brought to the construction site in disassembled form and already on the spot they are connected. Some modules are delivered ready-made.

Prefabricated wall panels with window openings reduce home assembly time

Directly at the production site, not only individual elements of the frame base are assembled, but also completed wall panels. In some cases, they are equipped with windows, heating system and facing. The wall modules are installed on the support frame and connected to the steel span structure by welding and threaded fastening.

The roof of a house made of metal profiles can be:

• lean-to;

  gable.

Depending on the shape of the house itself, the roof can be of a complex configuration. The most common types of roofs for metal frame houses are one- and two-slope.

Roof steel structure elements are load-bearing trusses, truss elements and span ceilings. The work itself is no different from the construction of a roof from other materials. Build first truss system and make a roof sheathing. Then they perform steam, waterproofing and lay the top coat of the roof.

This is how the roof insulation scheme looks like

For rafters, a galvanized C-shaped profile with a thickness of 0.8 mm - 1.2 mm is used. The crate is made of steel profile beams of rectangular or square section. Put on top of the crate vapor barrier film, insulation and waterproofing material. For finish coat houses use slate, metal tiles, ondulin and other materials.

House insulation

Warming of a house from a metal profile is carried out with polystyrene foam and mineral wool. Polyurethane foam is also used. The space that is filled with any material should become dense and effectively retain heat. All cavities inside the metal profiles are filled with foam.

From the inside, the surface of the walls of a metal frame house is covered vapor barrier material, and a dense film is attached outside to protect against the wind.

The openings between the wall panels are also filled with such new materials as gas and foam blocks, which contain insulation.

For external wall decoration, surface plastering is used, a natural stone, brick and siding.

Projects and cost of houses

The cost of a metal frame house includes the expenseon the:

materials;

• assembly work.

Can lower the cost a bit finished house by ordering standard assembly building. The price of housing itself is not much different from that of wood or brick. Two-storey cottage from sandwich panels, with dimensions of 7x10 meters will cost about 1.7 million rubles. However, the price depends on the configuration of the house. If you order only a warm circuit, then the cost of the "box" will be about 1.32 million rubles. A house with a rough finish costs about 1.75 million rubles.

Projects of houses from a metal frame are varied:

Fachwerk-style metal frame house

Small metal frame house attic floor, with total area 72 sq. m., designed for families with children. The house is convenient to use, with enough living rooms. In construction, ferrous metal is used to make load-bearing structures and galvanized thermal profile for wall panels. The structural elements of the house are connected using self-tapping screws.

The cottage is being built without the use of special equipment.

One-story metal frame house with a garage

It is made of metal structures that can withstand the necessary loads. Exterior finish – decorative plaster. Options for finishing - brick or siding. roof type - metal beams, roofing - metal tiles.

Classic house with attic

Quite often, buyers prefer projects two-storey houses or cottages with a residential attic. There are no restrictions on the design - the project can be chosen with a garage, a balcony and other extensions.

Conclusion

In terms of design, frame houses made of metal profiles do not impose any significant restrictions on architects. True, after the construction of the house, over time it will no longer be possible to reschedule, but this is a feature of many technologies.

Special attention should be paid to the insulation of the LSTK-house. Since the metal has good thermal conductivity, in order to exclude the appearance of cold bridges, a special approach to insulation and strict adherence to technology are required. For this reason, the construction of the LSTK-house should be carried out by professionals who will give a guarantee for their work.

frame houses confidently occupied a niche in private housing construction. Traditionally, the frame for them was made of wood, but modern technologies now allow you to quickly assemble frame houses made of metal profiles. Before you start building with your own hands, you need to familiarize yourself with this method of construction in more detail.

Is it worth choosing?

During construction own house there are always a lot of questions. For myself, I want to build the best, warmest and secure home, so the main question is: is there any experience of using such technology, is it trustworthy?

The metal frame house is assembled from individual elements which are supplied to construction site disassembled and reassembled

Frame houses made of metal profiles are simplified miniature versions of skyscrapers and large large-span buildings. The difference lies in the fact that in the construction of large buildings, massive steel rolled products (channels and I-beams) are used, and houses made of metal profiles involve the use of light thin-walled elements (LSTK). The raw material of manufacture is the same - steel. But the thickness, dimensions and bearing capacity of the products are different.

The use of large rolled metal for do-it-yourself construction is economically unprofitable, because:

• the cost of wall and floor elements increases significantly;
• a large mass of parts leads to an increase in the load on the foundation and an increase in the cost of the structure;
• loads during the construction of private residential buildings are negligible compared to the loads in large industrial and commercial buildings, so there is no point in using powerful beams and racks.

Therefore, we can say with confidence that the technology is time-tested. The advantages of a metal frame include:

• high strength of the material;
• light weight allows you to save on foundations as much as possible;
• resistance to decay and damage by fungus and mold;
• high mounting accuracy;
• cheaper transportation;
• lack of garbage and waste at the construction site4
• the possibility of building houses with large spans and free planning.

The disadvantages include:

Construction of metal structures - advantages and disadvantages

• susceptibility to corrosion (rust);
• high thermal conductivity (let heat through);
• reduction of evacuation time from the building in case of fire (loss of rigidity at high temperatures);
• the difficulty of fixing hinged interior elements and furniture;
• the need for potential equalization due to high electrical conductivity;
• limited construction area (not suitable for massive elements).

With all the shortcomings, it must be taken into account that the speed of construction of the structure is quite high, and the simplicity of the work allows you to do the construction yourself.

Construction technology

When doing work with your own hands, it is important to proceed in stages. Consideration of the issue begins with the development of project documentation.

Design stage

All frame structures are manufactured in one factory according to pre-ordered dimensions. Even if it is planned to construction works with your own hands, when designing, you will need the help of a specialist. Here, the future owner has three options that differ in cost:

Option complete assembly at home on steel frame(LSTK technology)

• choose from ready-made projects and order at the factory all the elements necessary for assembly (the cheapest);
• choose finished project and make small changes to it (optimal);
• order development individual project(dearest).

Typically, the project includes the following composition:

• floor plans, roofs;
• building facades;
• 3-D model of the house (not always);
• necessary drawings and assemblies for frame elements.

You can do without the help of specialists and develop a project on your own based on typical elements of a metal frame, but this is a difficult task.

Foundation construction

During the construction of any object, work begins with foundations. The choice of the type of supports is made on the basis of the geological data of the site. In most cases for light frame Houses the best choice for erection with their own hands will be: shallow strip foundation, pile-grillage foundation.

The first type allows you to put on foundations 1-2 storey houses from lightweight materials good performance soil. The second option is suitable for heaving soils with not very good strength characteristics.

Frame assembly

From the factory, LSTK frame parts are numbered and individually packaged. This greatly simplifies the assembly process with your own hands. Included are:

• vertical and horizontal frame profiles with the necessary openings for utilities;
• fastening kit.

Parts come in the required length, nothing needs to be cut or adjusted. The do-it-yourself assembly process resembles a children's designer. It is only necessary to use the manufacturer's instructions, install the profiles in the design position and secure with the proposed connecting elements. At this stage, difficulties should not arise if you follow the instructions and carefully check the markings of the elements.

Important! For the manufacture of the frame, it is recommended to choose a Z-section profile, in which grooves or perforations are provided. Such an element, although made of a "cold" material, allows you to retain heat. The second name of such an element is a thermal profile. This is the most desirable option for private residential housing construction.

Insulation and building envelopes

The final stage in the assembly of the building box will be the sheathing of the frame. Works here are carried out using the same technology as for wooden frame houses. Sheathing options:

1. Assembling structures with your own hands. outer side at the same time, the metal frame is sheathed with a profiled sheet or a glass-magnesium sheet, a heater is laid between the racks. Mineral wool or extruded polystyrene foam can be used as thermal insulation. With a limited budget, you can consider more cheap option- Styrofoam. When using foam or mineral wool, a vapor barrier with inside and waterproofing from the outside. From the inside, the lining can be made with drywall. The outer finish is fixed to the profiled sheet.
2. Sandwich panels. They are made at the factory, where they can be painted in desired color. Simplify and speed up the assembly process. Advantages include: resistance to aggressive influences external environment, to high temperatures and fire, high thermal insulation characteristics, environmental friendliness and safety for humans. Another plus will be that the panels simultaneously act as insulation and exterior finish reducing labor costs.
3. Heat blocks. modern material, which is a “bricks”, including a layer of porous expanded clay concrete, a layer of expanded polystyrene (polystyrene) grade 25 and a facing layer of expanded clay concrete. The cladding is made of high density material and is ready for painting. Plus technology - the simultaneous creation of thermal protection and enclosing structure. Masonry seams are accepted no more than 5 mm. Normal masonry mortar for bricks cannot ensure that this requirement is met, therefore special mortars or glue are used. Reinforcement is required every 4 rows of blocks to increase strength.

Houses on a metal profile frame are a new word in the development of frame construction technologies. Let's figure out how quickly and with least cost build such a house with your own hands.

The construction of a private house today has changed a lot due to the emergence of new technologies. wooden frame allows you to build a structure very quickly and provide good performance characteristics. Using a metal profile frame for building houses with your own hands - further development frame technology. Let's see what are the benefits this method and how to build such a house with your own hands.

Advantages and disadvantages

The technology of building buildings on a metal profile frame assumes that all frame elements of walls, ceilings, and roofs are made of metal. The thickness and shape of the profile for each section is calculated separately, based on the load being tested. This method of construction allows you to achieve the following results:

• Reducing the weight of the finished building.
• Speed ​​of construction.
• Reduction of tools necessary for construction: since the profile is manufactured in the factory, a drill, a plumb square, etc. become unnecessary.

The frame is filled with insulation panels, which are selected for the conditions of each region. Thus, it is possible to achieve the required indicators for protection against freezing. Frame houses are warm and economical: since there is no heat loss, it is possible to significantly save on heating.

Other advantages of houses built using this technology are:

• Ease of disposal. Unnecessary structure does not need to be broken. You can disassemble the house, like a designer, letting the metal of the frame be melted down. The environment does not suffer either.
• Durability: the metal does not burn, does not rot, practically does not deform from temperature changes.
• Construction can be carried out at any time of the year, without interruption for the cold period.

Usually frame construction used for the construction of small buildings with a height of one or two floors. The height of the walls of such an object is usually no more than 6 m, and the span is about 12 m. The limiter is the bearing capacity of the rafters. roof trusses 24 m long and more require the use of a special profile, they are difficult to manufacture and install.

There are several features that must be considered when choosing a frame house:

• Good thermal protection translates into a need for a good ventilation system. The house, in fact, is a thermos, and without effective ventilation system it will be wet. And this suitable conditions for the development of fungi.
• The walls of the frame house will not be able to hold a lot of weight. It will not be possible to hang shelves on them or drive in a dowel for a picture.
• Although the metal frame is made of corrosion-resistant alloys, care must be taken that it does not come into contact with moisture. Otherwise, corrosion processes can cause destruction of structural elements.

Given these features, living in frame house may with great comfort, and it is not very difficult to build it with your own hands. But careful observance of technology and purchase is required. quality materials for construction.

Assembly technology

The production of a frame house is carried out in several stages.

The design stage involves the preparation of documentation for the factory that will produce the profiles for assembling the frame. Even if you plan to build a house yourself, at this stage you need to resort to the help of a specialist. Incorrectly manufactured frame parts can make construction an impossible task. Therefore, it is worth choosing and implementing one of three options:

• Choose a ready-made house project. The cheapest option. In the variety of options developed by designers, there is almost certainly a solution that combines an affordable price and a fairly high quality.
• Having chosen a ready-made project, order its modification for your own needs. This may include changing interior layout, the addition of new elements (bay window, attic, etc.) or vice versa, the rejection of complicating details in order to reduce the cost of construction.
• Order the development of the project from scratch. This is the most expensive and time consuming option. But on the other hand, it guarantees that the house will turn out to be unique in design and truly convenient for your family.

When the project is ready, the frame elements and insulation panels are made, and at this time work is underway to create a reliable foundation for the future home. Light weight allows for pile foundation or technology based on the use of SHS supports. Both methods allow you to make the foundation quite quickly.

Next, the frame is assembled. In fact, this procedure resembles a game with a children's designer, only the details are very big size. Since all elements are prefabricated, there is no need to waste time measuring and drilling holes. It is possible to assemble the frame completely in a few days.

At the next stage, the frame is sheathed with insulation panels. In general, this stage is similar to the work carried out during the construction of houses on a wooden frame.

When this stage is over, communications are brought into the house and the room and facade are being finished.

Necessary materials and tools

All types of metal profile (it is also abbreviated as LSTK) for house frames are made of structural steel using cold dies. Each sheet is applied protective covering zinc to resist corrosion. The coating thickness varies from 18 to 40 microns. The thicker the coating, the more expensive the profile, but also the higher its durability. The most expensive profiles are hot-dip galvanized.

The thickness of the sheet from which the profile is made is also different. The thinnest is 0.7 mm, the thickest is 2 mm. The thicker the steel, the higher the bearing capacity of the LSTK. However, as the thickness increases, the weight and cost also increase. Therefore, the thickness of the metal and the type of profile are calculated by specialists based on the loads that the frame will carry.

Today, LSTKs enter the market from dozens of sources: foreign and domestic, small factories and large steel mills. It is difficult to recommend a specific manufacturer here. It is worth looking at the quality of the metal (no traces of rust, coating chips, etc.)

There are several types of profiles:

They are also divided into subspecies depending on specific tasks:

It is impossible to determine which profile to put on each site without special knowledge. That is why it is better to entrust the drafting of a frame house to a specialist.

The set of tools may differ slightly, depending on which manufacturer the LSTCs are ordered from. But almost always a set of profiles comes based on a screwdriver assembly: everything is numbered, laid out in the appropriate order, equipped with the appropriate fasteners.

Do-it-yourself frame house from a metal profile. Step-by-step instruction

Construction process frame building almost the same, even though a metal frame is used, even a wooden one. Here are the basic steps for building a house on a finished foundation:

1. Based on going bottom trim. This is a very important stage, since it is here that the foundation for the future building is laid.
2. The main ones are placed in the corners support posts. It is very important to set them strictly vertically. When using a metal frame, such a sheerness is easier to achieve, but it still does not hurt to check the correct installation with a plumb line.
3. Additional racks are attached between the main support posts, they are connected into a single frame of the walls with the help of crossbars and jibs.

If you plan to build multi-storey structure, two frame options can be used. In the first case, the support posts pass through the entire frame. Then the two floors of the house represent, as it were, a single whole. In this case, the strength of the structure is higher, but it is more difficult to build, since a longer and heavier profile will be needed. In the second case, the frame of the first and second floors are separate things, which are then connected to each other.

On this frame of the house is ready. In principle, assembling such a structure is no more difficult than assembling a constructor. It is only important not to mix up the details and carefully perform each operation.

Here are some tips from builders who are professionally involved in assembling frame houses:

• In the work you will need an assistant, and preferably several. One can only assemble some small structure, like garden gazebo, and even then the hands will be greatly missed.
• Since metal conducts temperature much better than wood, a metal frame can create so-called. "bridges of cold". So that the house on the frame of LSTC does not lose heat, you should take care of high-quality insulation external and internal walls the buildings. For this, modern insulation materials: styrofoam, mineral wool.

It is quite possible to build a building on a frame from a metal profile with your own hands. Modern technologies allow you to make such construction fast and not too laborious. But it is necessary that the frame is properly designed and made of high-quality metal. Then your house will be warm, durable and cozy.
