What are LSTC designs? Calculation, reviews, photos

The designs of LSTC today are quite widespread, the area of their use is quite diverse. The abbreviation stands for light steel thin-walled structures.

Application area

These structures are actively used in the construction of public buildings, cottages, shops, as well as garages. Such steel systems quite often today can be found at the heart of hotels, sports facilities, medical centers. Private builders have adapted such structures for erecting mansards, roofs, the latter of which have wide spans. In the countries of Europe, LSTCs have been spread for half a century.

Characteristics of LSTC

The LSTC constructions are lined up using a material whose thickness does not exceed 4 mm. The works use galvanized sheet, which is produced by the cold rolling method, but is realized in rolls. At the heart of the designs are the profiles, which in the production process were formed by the cold method. Their cross-section can be open or closed. Feature LSTK allows you to apply them when building enclosing structures, among which you can select walls, as well as ceilings, but this is not a complete list.

LSTC designs can have thin-walled profiles that were previously perforated in the wall region, they are also called "thermo-profiles". Their main purpose is to increase the thermal characteristics of the thermal contour of the building and ventilation in the heat insulator.

The described components are mated by means of screws, which are of excellent quality and assume self-drilling installation, and they are made of corrosion-resistant steel. Alternatively, carbon steel can be used for such products, which is coated in a cadmium or zinc composition. To get acquainted with the assortment of profiles, for example, the production of LLC "Astekhhouse" can be found at http://astekhome.ru/lstk.

Technology of LSTC construction

LSTC structures are built using materials that do not have a metal composition, such as plasterboard, gypsum board, cement-particle board, OSB , etc. These coatings are installed on profiles, or in other words, racks. This is done both outside and inside buildings. The technology implies the rejection of wet work, which is now very common due to the convenience and speed of work.

Choose this technology also because the building is lightweight, so its mass is 30 kg / m ² . As for the two-storey building, the weight increases to 38 kg / m ² . But this does not prevent the buildings from being stable and durable. That is why LSTC are built in seismically dangerous zones, to the phenomena of which they are particularly stable. All this is combined with the ease of assembly, which raises labor productivity by 2 times.

Customer Reviews

LSTK-constructions are quite actively used in private construction. Consumers, choosing this technology, note that with its help it is enough to build mansard floors that do not exert a significant load on the foundation. Many residents of seismically dangerous areas say that it has become for them an indispensable solution for erecting houses, which manifest themselves during earthquakes especially staunchly. But with the arrangement of a ventilated facade, and not at all without steel structures. Their consumers choose much more often wooden ones. Buyers note that steel elements serve for a longer period of time, do not require repair, and after getting wet they do not deform. Buyers prefer metal structures, if they are faced with the task of replacing a flat roof with a pitched roof.

Reviews about economy

Today, perhaps, there is not a single person who does not seek to save money in repair and construction. If we replace concrete with steel structures, as the owners of private houses and apartments say, it is possible to save at the time of transportation of the material, during its installation and subsequent operation, because concrete requires repair when the building shrinks, and steel elements do not. In addition, private masters and professional builders argue that they choose steel more often than brick and mortar, since the installation of the first material takes less time and does not require the use of expensive construction equipment.

Features of LSTC calculation

LSTK-designs are calculated before designing. First of all, the data on the loads that will affect the load-bearing structures are taken into account. What are the forces that will arise in the columns, cover runs, cover farms, as well as crane beams, but this is not the entire list. The next step is to calculate the cross section. It is important to determine which profiles are expected to be used, and then you can start constructing the elements.

Light steel thin-walled structures (LSTC) should be assembled by means of the most simple and strong joints. At the same time, bolts can be used, but the welding method is not respected, since there is a possibility of failure, which will weaken the section of the profile. In the calculation, specialists will take into account the external influence of the environment. This will reduce the influence of wind, precipitation, and soil vibrations. In order to install an easy construction, it will have a sufficiently deep foundation, and it should be taken into account that seismic phenomena should be minimal on the construction site.

Fencing LSTK

LSTK-designs, reviews about which, as a rule, only positive, can be used and as fences. LSTK can be used in tandem with insulation according to the type of ecowool, which only improves the quality of the system. If you compare a wall that is 100 mm thinner than that built from lightweight cellular concrete, then it loses less heat by a factor of 1.5. This allows us to state that the savings in heating during the cold season will be impressive. In addition, it is possible to win a free space in the premises of the dwelling. After all, the thickness of the walls will be less.

Advantages of LSTC in front of structures from other materials

LSTK-designs, photos of which can be seen in the article, win the battle and have so traditional today and many years ago a brick wall. They are often used in high-rise construction, because such fencing systems greatly speed up the work, they have much less workload, and for the installation, you do not have to resort to expensive help from professional builders. But the private master, in addition, can avoid the need for wet work associated with the solution: his batch and styling. Construction equipment may be needed only in order to have the opportunity to raise steel elements to the required floor, which is absolutely irrelevant for the conduct of private construction. But if you are building a two- or three-story house, you can exclude the rent of heavy equipment for lifting structures by using the winch.

If you use the LSTC at home, the enclosing structures, as well as the main walls, can be erected from them, and it becomes possible to build a house with up to four floors. If you are just going to build your house, then a lot of concrete work can be replaced with technology, based on LSTK. This will save on materials, speed up the process and eliminate the need to engage in wet work, which requires the master to have certain skills that are not required when assembling a house from light steel elements. But the design calculation LSTK is more preferable to entrust to professionals.
