CONSTRUCTION OF HOUSES ON TECHNOLOGY LSTC FOR FAMILIES WITH LOW INCOME
Having your own house (even a small one) is the dream of every second person. Modern construction is moving in parallel with the progress, so in order to build a residential facility, today does not require a lot of time. For example, frame country houses and country cottages from LSTK can be quickly erected in a short time, and for a rather modest budget by the standards of construction. This technology is beneficial not only to potential owners of such objects, but also to businessmen who earn in this way. Consider the main nuances of frame construction.
A FRAME HOUSE OF LSTS: PROS AND CONS
Lsts represent the metal elements having the combined mechanism (Light Steel thin-Walled Designs).
Advantages of construction of houses on LSTK technology:
Short time of construction of the house from LSTK is the main advantage of technology for fast-built buildings.
Light weight (for example, 1kV meter frame weighs up to 25kg).
Saving labor and materials.
Flexibility of the building layout, due to the easy replacement of individual elements and their movement.
High seismic resistance, due to the strength and connectivity of structures.
Variability of exterior finish (well combined materials such as wood, OSB plates, etc.).
Weather resistance, providing in addition to the durability of buildings the possibility of year-round construction (galvanized metal frame has a long service life).
Fire resistance and safety of materials for human health and life.
It is possible to erect buildings at any time of the year (if not to use foam concrete as a heater).
Frames of lsts have disadvantages such as:
High cost of materials. But a quality product cannot be cheap. In addition, you can make your own hands lsts profile on a homemade rolling machine.
Possible thermal conductivity in cold bridges. This problem is successfully solved by the use of modern thermal insulation materials and technologies in construction. The house is insulated so that there was no metal contact with the environment. A thermal profile is used in the walls of the frame. It has a perforated base, which almost completely eliminates heat loss.
Interesting fact! Metal structures have left a long trace in history. At the beginning of the XIII century was built a metal dome in the construction of the Paris bread market, and after 78 years there was a famous and still very popular design of metal – the Eiffel tower.
THE MOUNTING FRAME HOUSES OF LSTS
The construction of each house begins with the Foundation. What is the best Foundation for a house of lsts? The process of construction of frame houses is simple. Frame construction of houses on LSTK technology eliminates the need for installation of a fully buried Foundation. For prefabricated frame structures, screw piles are the best Foundation. They can be quickly installed and significantly reduce the lead time. Also screw piles can be configured to optimize the load distribution even after the construction of the house. But in the budget the projects, you can use a strip Foundation. It is a little cheaper, but much more time-consuming to install.
After the Assembly of the frame. Then the insulation is performed using mineral wool or other types of insulation. For example, in budget projects clings formwork and foam filled the entire structure.
Steel “skeleton” (is a frame of the floors of the lower floor, walls and truss forms) is formed from thermal profiles with different cross sections. In turn, steel profiled beams serve as bearing elements of internal floors (intermediate supports are not required). Assembly should be carried out using self-tapping drilling screws. Engineering communications should be laid directly inside the floors and partitions. In the cells formed by the supporting elements of the frame, a mineral wool insulation is usually laid. It is important to provide it with high-quality ventilation, so it is advisable to make a ventilated facade from the outside. This will allow the material not to dampen in the winter, as a result, to serve longer. The covering of the building can be any by the order of the client.
It is worth noting that the use of metal profiles can be a “salvation” for those who need reconstruction or attic superstructure. Bearing walls will not be affected. In this case, the construction time will be reduced to a minimum.
The cost of the house from LSTK turnkey depends on several factors:
the scale of order and type of the object;
the status of the company by;
Prices for 1m2 frame house in the domestic market range from 50-70$. Although there are budget or promotional offers for $ 40 per m2. They are more concerned with the construction of small country houses.
This type of business is considered not too profitable – about 20%. After all, consumables of galvanized metal, which in itself is expensive. But on the other hand, high profitability is not the main indicator for attracting investment. Better 20% of a thousand than 80% of a hundred. In this business, an important role is played by the high cost and demand for the product. The contractor earns, as a rule, from 1/5 to a quarter of the cost of the order. On average, this amount is about 25-30 thousand dollars. As for the timing, the country cottage team of 4 builders going in less than 2 weeks.
Having mastered the technology to perfection, having picked up competent personnel and using materials of the checked producers, it is possible to build quickly:
quality country houses;
gazebos and other extensions.
