Today, the LSF structure has attracted the attention of many engineers and investors. The LSF structure has many advantages, the most important of which is its suitability against earthquakes. Also, this structure has disadvantages.
What is lsf structure?
This light structure, which is called LSF for short, is one of the modern construction systems. This structure is used for a maximum of 5 floors, which is of great interest to civil engineers today. In the LSF structure, it is made of cold-rolled steel sheets, and the external facade is cemented outside, as well as wood, glass, stone, brick, etc. is used You can use the LSF structure together with other structures. The weight of the LSF structure is about 50% less compared to other structures, which is a very important advantage against earthquakes, and it is very similar to a wooden structure. . This structure is based on the design of Ostad and Vadar and Track, which is designed with the help of cold-rolled galvanized steel profiles, an image of the desired building. The roofs of this structure are very light and usually sloped and are made using metal trusses. In the rest of the building, materials such as stone, brick and PVC are used. Also, interior walls are designed with wallpaper and painting on plaster panels.
کاربرد سازه lsf
In our country, the lsf structure is the focus of engineers for medium-sized projects. This structure is used in many cases that we have witnessed all the applications of this structure by implementing this structure. Among the most important uses of this structure, the following can be mentioned:
-industrial units
-Educational buildings
– Multi-unit buildings
– Increasing the number of floors on the roof of buildings
– Reconstruction of earthquake affected areas
– Construction of temporary residences for people affected by the earthquake
Sports buildings
– Small commercial buildings
Construction of small and suitable dormitories for students
– Construction of roadside motels
Construction of residences for pilgrims in religious cities
The cost of the lsf structure
The cost of lsf structure is high compared to other structures such as concrete and metal; Of course, the operation time of the concrete structure is about 5 times that of the LSF structure, and this double time creates a series of higher costs (staff wages, rents and insurance of people), which causes the cost in most cases. Both structures do not have that much difference. It can also be said that the main cost of this structure is spent on galvanized metal parts, and otherwise, the consumption of cement and steel in LSF structure is less than other structures.
How to implement the lsf structure
In the implementation of the lsf structure, like other structures, in the initial stage of the work, a schematic plan and a model of the building desired by the client are made; In this preliminary plan, it has been tried to define the wind and earthquake resistances and the thickness of the columns and beams, as well as all the water, electricity and sewage connections to the building. After this stage, it is time for foundation and skeletonization. The walls of the building are made hollow, and the inside of the walls is usually covered with plaster or knaf tiles, cement panel or cement board, osb board, shingle roof and vapor barrier, colored sheet and foam, stone wool with different densities according to the conditions. Geographical and climatic conditions. The next stage is the external and internal coverings of the roof and the last stage is the electrical, mechanical, door and window installations.
