LSTK-technology is called a special alternative type of frame construction. The recently increased popularity of this technique is primarily due to the possibility of reducing the cost of the construction of buildings and structures, as well as its environmental safety.
What is LSTC?
Actually, the abbreviation LSTK itself stands for light steel thin-walled structures. The basis for buildings erected by this technology are metal bent profiles of different sections connected by bolts. To improve the heat-saving characteristics of such houses, special elongated holes are made in the walls of steel elements.
As a heater, any modern insulating materials can be installed in the metal frame. Most often it is mineral wool or polystyrene foam. Either drywall or plywood is used as the inner lining. Outside, such buildings and structures are finished with siding, clapboard, board or brick.
Main areas of use
LSTK (construction technology) can be used in the construction of:
Also, this technology is often used in the reconstruction of old buildings, the construction of attic floors and the assembly of ventilated or stucco facades. In most areas of our country, LSTK-construction technology can be used. Perm, Krasnodar, Vladivostok, Moscow, Yekaterinburg - everywhere such houses will be convenient for living and will last a long time.
The main advantages of technology
The advantages of buildings and structures erected according to the LSTK methodology include, first of all:
Cheapness. Savings are achieved due to the simplicity of design, the absence of the need to use heavy equipment during installation, etc.
Ease of construction. LSTK frame buildings are assembled in just a few days.
No need to build powerful expensive foundations. For the manufacture of profiles, according to standards, steel with a thickness of not more than 3 mm can be used. Therefore, the frame walls erected from them weigh a little.
Strength and durability. LSTK is a construction technology that allows the construction of very sustainable buildings and structures. Such a profile is made of cold - rolled galvanized steel sheet with a yield strength of 250 to 350 MPa. That is, the frame of the structure during operation will not corrode. Sometimes, for the construction of such buildings, a special galvanized profile is also used, additionally painted or coated with a polymer composition. To connect the parts during the assembly of buildings, special fasteners made of stainless or galvanized carbon steel are used.
Ecological safety. Steel, like wood, does not emit any harmful substances into the environment. At the same time, no harmful substances are used to process LSTC profiles.
Fire safety. Most often, when siding buildings of LSTK, metal siding and drywall are used, and mineral wool is used for their insulation. All of these materials, like steel itself, are non-combustible.
Frame construction using LSTK technology, among other things, also has such advantages:
seismic stability of buildings under construction;
high precision assembly;
excellent performance of the facilities under construction;
wide opportunities in the field of architectural planning.
Seismic stability LSTK
LSTK is a construction technology used, including during the construction of buildings in those areas where there is an increased risk of earthquakes. The fact is that such a profile is elastic (due to various additional ligaments). According to the assurances of the developers of LSTK technology, buildings assembled on such a frame can withstand earthquakes with a power of up to 9 points without harm to themselves. Of course, most regions of Russia are not considered as seismic hazardous. However, such strength and elasticity of the frames indicates their highest quality.
Construction accuracy
This is one of the most important advantages of LSTC technology. The design of such buildings is performed using special 3D computer programs. All profiles are cut and packaged at the production stage. That is, all that builders need to do is assemble the wall panels from the finished material, marked accordingly. No waste remains during the construction of the building, and all its elements are obtained geometrically absolutely verified.
Performance characteristics
The convenience of living and doing business is another plus that distinguishes such house construction. LSTK technology allows you to build really comfortable buildings. Unlike wooden ones, they never shrink and do not react in any way to changes in air humidity. That is, even after several years of operation, cracks do not appear in the walls of such structures, and the enclosing structures themselves retain their exact geometric dimensions. All this ensures maximum heat retention.
Architectural Planning Opportunities
Since the design of such structures is carried out using computers and special software, they can have a variety of exterior, often quite original. In addition, the LSTK technology allows you to erect structures without the use of intermediate supports with spans of up to 12 m, and in the case of reinforcing structures, up to 15 m. Thanks to this feature, the internal space of houses can be designed as rationally as possible. In addition, this allows you to conveniently place elements of communication systems and integrate additional segments into the walls of various kinds (niches for built-in appliances, pantries, etc.).
What are the disadvantages of LSTK (construction technology)
By and large, only an insignificant weight of the structures themselves is considered an indirect drawback of this technique. On springy soils in the spring, light structures of LSTK can rise above the ground. However, due to the strength of the material, cracks in the walls usually do not appear. In order to avoid lifting, thorough geological surveys are recommended before building the building.
What other disadvantages does LSTK (construction technology) have? Another small drawback of this technique is the fact that in such houses it is difficult to hang various kinds of household items on the walls: paintings, shelves, cabinets. Indeed, in most cases, the inner lining on the LSTK frame is made of drywall, which has a low bearing capacity.
Features of the methodology of building houses
A shallow or columnar foundation is the best variety of foundations for LSTK houses. The construction technology in this case is as follows:
All elements are laid out according to the installation scheme for the area of the foundation.
Waterproofing tape or pillars.
The support profile is attached to concrete by means of anchor bolts. Previously, the marking is applied to the foundation itself.
All supporting wall panels are sequentially mounted on the support profile, according to the marking made at the enterprise.
The frame of the internal walls and partitions is installed.
Mounted ceiling panels or trusses LSTK. The former are often not used. In this case, the basis for the ceiling are the lower truss belts.
The construction of buildings using LSTK technology is nearing completion with the installation of insulation and wall cladding.
Features of assembly of ventilated and stucco facades
These elements are used primarily to improve the appearance of buildings and their heat-preserving qualities. The LSTK profile during the construction of ventilated facades and roofs is used to assemble the frame. The thickness of the elements in this case is determined by the material used to erect the building envelope, as well as the area of the latter.
The traditional ventilated facades of LSTK are constructed using simple technology. That is, the frame itself is first mounted, then insulation plates are installed. At the next stage, the facade is fitted with a diffusion film. Next, additional elements are mounted to equip the ventilation layer and lining is performed.
In addition to the construction of traditional, LSTK-profile can be used for the construction of plaster facades. The latter can be light or heavy, insulated or simple. They are also being built using conventional technology. First, the frame from the profile is mounted on the wall. Next, sheets of expanded polystyrene are installed. Then plastering is carried out using a masking net.
Floor assembly
Interfloor ceilings - structures for the construction of which LSTK (construction technology) is also used. In Ufa, St. Petersburg, Astrakhan and other cities, buildings are being built with such strong and durable ceilings and floors. For the installation of ceilings, a profile having a Z or C-section is usually used. Rigidity is ensured by the use of steel corners. After mounting the beams, the crate is additionally assembled. A vapor barrier film is attached to it. Pre-installed insulation. Sheathing is most often done using gypsum fiber sheets. From the attic or attic side, profiled steel sheets (with rubber gasket to provide noise insulation) can be attached to the beams and crates. The rough floor itself is made either from gypsum boards or from plywood.
LSTK: construction technology. Consumer Reviews
The opinion of their owners on such structures was generally quite good. Living in such houses is quite convenient. The advantages of designs of this type, many attribute mainly the ease of assembly. The majority of owners consider LSTK houses a very low level of sound insulation. All percussion sounds on the metal frame are carried instantly. Many note the fact that, for example, a person on the second floor in such a house can hear perfectly how his family members walk on the first. To solve this problem, the owners of LSTK buildings advise using special rubber gaskets on the rails during their construction.
LSTK - construction technology (reviews - direct confirmation of this), which is relatively cheap. In addition, such buildings are also praised for the microclimate. In winter, they are warm enough, and in summer it is not particularly hot. However, the selection of a heating system and climate control equipment is usually advised to approach responsibly. Among the pluses of LSTK houses, among other things, include quick heating of air in all rooms when the boiler is turned on. Sometimes condensation appears on the walls of such houses. But this happens quite rarely.
Unfortunately, there are not too many houses in our country built using LSTK technology. Therefore, there are quite few reviews about them. Mostly attic farms and ventilated facades are built using this technique. Owners of suburban areas have uniquely positive opinions about such constructions. The advantages include primarily light weight, strength and durability of structures.
Conclusion
Cheapness, environmental friendliness, fire safety - all of these advantages, of course, differs LSTK - construction technology. Photos of houses built using this technology, presented on our page, clearly demonstrate their quite attractive appearance. Thus, due to the huge number of advantages, this technique in the future will surely gain more and more popularity among domestic owners of suburban areas.
