Abstract: with the soaring house prices and increasing pressure on life, buying a house has become a major problem for everyone in recent years.
The structure of the light steel villa is relatively simple. The floor is mainly composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, supports, connectors, etc.
it has light self weight, good stability, very good seismic and wind resistance performance, and the light steel keel can also be recycled, which is green and environment-friendly.
The floor of light steel villa is composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, support, connector, etc.
The materials used are oriented particleboard, cement fiberboard, and plywood. On these lightweight floors, 316 ~ 365 kg load can be borne per square meter.
The weight of the floor structure system of light steel villa is only one fourth to one sixth of that of the domestic traditional concrete floor system, but the floor structure height will be 100 ~ 120 mm higher than that of ordinary concrete slab.
The roof system of light steel villa is composed of roof truss, structural OSB panel, waterproof layer and light roof tile (metal or asphalt tile).
The roof of light steel structure can have a variety of combinations in appearance. There are many kinds of materials.
On the premise of ensuring the waterproof technology, there are many options for appearance.
The wall of light steel villa is mainly composed of wall frame column, wall top beam, wall bottom beam, wall support, wall panel and connector.
Light steel villas generally take the internal transverse wall as the load-bearing wall of the structure, and the wall column is a C-shaped light steel component.
Its wall thickness is usually 0.84 ~ 2mm according to the load, and the spacing between wall columns is generally 400 ~ 600mm. The wall structure layout of light steel villas can effectively bear and transfer vertical load, and the layout is convenient.
In order to ensure the thermal insulation effect of light steel villa, the thermal insulation materials used in the outer wall and roof of the building can be used for a long time.
In light steel villas, in addition to filling the glass fiber between the wall columns, a layer of thermal insulation material is pasted on the outside of the wall to effectively block the thermal bridge from the wall column to the outer wall panel;
The joists between floors are filled with glass fiber to reduce the heat transfer through the floors; Glass fiber is filled between wall columns of all interior walls to reduce heat transfer between household walls.
1. The light steel villa has light weight, good stability, very good seismic and wind resistance performance, and the light steel keel can also be recycled, which is green and environment-friendly.
2. The light steel house wall is added with thick glass fiber cotton, which has good sound insulation and thermal insulation effect, excellent fire performance and excellent quality.
Now the whole industry is vigorously developing prefabricated buildings, which is what we call light steel villas.
3. The construction speed of light steel villa is very fast, which is 7-8 times that of brick concrete buildings. Moreover, the light steel villa is assembled without any lifting and hoisting equipment.
The weight of light steel villa is one quarter of that of traditional concrete buildings, which is very light, but its stability is excellent. Moreover, the houses with light steel keel structure have very good seismic and wind resistance.
4. Because the steel materials used in the structure are processed in factory, the structural accuracy of light steel structure villa is quite high.
The structural system of a villa is composed of tens of thousands of components, and the average error of each component is less than 2mm, which ensures the quality of the house, which can not be achieved by traditional building methods.
5. Safe and reliable
The housing with steel as the main building material has high bearing capacity per unit volume, is more stable and firm than the traditional brick wood and brick concrete technology, has better seismic performance, wind resistance, waterproof and fireproof performance, and also has heat insulation and sound insulation functions. Steel has good ductility and can better consume the energy brought by earthquake, so it has good seismic performance and high structural safety, which ensures the safety of residence.
6. Simple construction and short construction period
All components are prefabricated in the factory and only need to be assembled on site, which greatly shortens the construction cycle. A 6000 square meter building can be basically installed in 40 days.
7.Durable and easy to repair
The light steel structure house designed by computer is durable and can resist bad weather. It only needs simple maintenance and maintenance.
8. Beautiful and practical
The lines of steel structure buildings are simple and smooth, with a sense of modernity. The color wall body has a variety of colors to choose from, and the wall can also use other materials, so it is more flexible.
9. Green and sustainable
All houses have a certain service life. Generally, the raw materials removed from the houses with brick concrete structure can not be reused, and a large amount of garbage will be generated to pollute the environment. The steel of steel structure residence can be 100% recycled to realize recycling. It has less environmental pollution during construction and demolition, which meets the requirements of housing industrialization and sustainable development.
10. More rational use of space
The light steel structure does not need the large beams and columns required by the traditional civil house and concrete house, which makes the indoor space larger. According to statistics, compared with the concrete house, the light steel structure house has increased the effective building area by 5% – 8%.
