Is the light steel villa firm?

Light steel villas are solid and reliable, and the state is also vigorously supporting the construction of such villas.

Light steel villa is also called light steel structure residence, and its main material is light steel keel synthesized by hot dip galvanized steel strip through cold rolling process. Through accurate calculation and supporting combination of accessories, it can play a reasonable bearing capacity and replace traditional houses.

1. Compared with traditional houses, light steel villas have their outstanding advantages:

(1) The manufacturing of light steel structure fittings for light steel villas is highly industrialized, mechanized and commercialized.

(2) The site construction of light steel villa is fast, which will not affect the nearby residents and is conducive to civilized construction.

(3) The steel structure building of light steel villa is an environmentally friendly and sustainable product.

(4) Light steel villa has light weight and good seismic performance.

(5) The comprehensive economic index of light steel villa is not higher than that of reinforced concrete structure.

(6) Compared with brick-concrete houses, light steel villas can avoid the waste of resources caused by burning bricks with soil.

(7) Due to the small thickness of the light steel structure wall, the light steel villa can increase the effective use area compared with the brick-concrete structure;

(8) Compared with reinforced concrete houses, light steel villas can be recycled in the future, but concrete can't be recycled. It must be construction waste, causing environmental pressure. Moreover, it takes 40 years for concrete to completely dry, so it is easy to cause indoor humidity, which is not conducive to human health. The light steel structure does not use concrete at all, so there is no such problem.

(9) Light steel villa has good seismic performance. Because the earthquake activity is left and right, up and down, the light steel structure connected with screws forms a safe and stable box body, and the wall collapses or the floor slab falls off due to earthquake shaking, which will not endanger personal safety.

(10) The light steel villa is constructed by dry method, which will not waste water information. And the cost is saved.

Second, the floor structure of light steel villa

The floor of light steel villa is composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, bracket and connector. The materials used are oriented particleboard, cement fiberboard and plywood. These lightweight floors can bear a load of 3 16 ~ 365 kg per square meter. The weight of the floor structure system of light steel villa is only one quarter to one sixth of that of the traditional concrete floor system in China, but its floor structure height will be higher than that of ordinary concrete slab 100 ~ 120 mm.

Third, the roof system of light steel villa

The roof system of light steel villa consists of roof truss, structural OSB board, waterproof layer and light roof tile (metal or asphalt tile). Light steel roof can have many combinations in appearance. There are also many kinds of materials. On the premise of ensuring waterproof technology, there are many choices for appearance.

Four, light steel villa wall structure

The wall of light steel villa is mainly composed of wall frame column, wall top beam, wall bottom beam, wall support, wallboard and connectors. Light steel villas generally use internal transverse walls as load-bearing walls, and the wall columns are C-shaped light steel members. The wall thickness is generally 0.84 ~ 2 mm according to the load, and the spacing between wall columns is generally 400 ~ 600 mm As a wall structure arrangement, light steel villa can effectively bear and reliably transmit vertical load, which is convenient to arrange.

Five, light steel villa building thermal insulation and energy saving technology

In order to ensure the thermal insulation effect of light steel villas, the thermal insulation materials used in the external walls and roofs of buildings can be used for a long time and can be used for thermal insulation. In general light steel villas, in addition to filling glass fiber between the wall columns, a layer of thermal insulation material is pasted on the outside of the wall, which effectively isolates the thermal bridge from the wall columns to the external wall panels; Joists between floors are filled with glass fiber to reduce heat transfer through floors; Glass fiber is filled between the wall columns of all interior walls to reduce the heat transfer between walls.

1. Building fire prevention technology

One of the most critical problems of light steel villa is the application of fire prevention technology, and the fire resistance rating of light steel villa is grade four. Fireproof gypsum boards are attached to both sides of the inner wall and the ceiling of the light steel villa, and the common firewall and the residential wall are protected by gypsum boards with a thickness of 25.4 mm (1 inch), which meets the fire protection requirements of 1 hour. In addition, the glass fiber filled between the wall column and the floor joist also plays an active role in fire prevention and heat transfer.

2. Building sound insulation technology

Glass wool is filled between the inner and outer walls of the light steel villa and the joists of the floor, which effectively prevents the audio part from spreading through the air. For the impact sound transmitted through solid, the following structural treatments are made: for the entrance wall, two walls are formed with two wall columns, leaving a gap in the middle; For the small keel of fixed gypsum board for ceiling, the elastic structure with small grooves is adopted to effectively reduce the transmission of solid sound between floors.
