Advantages of light steel villas

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

(1) The light steel structure accessories of light steel villas are manufactured with a high degree of factoryization and mechanization, and a high degree of commercialization.

(2) The on-site construction speed of light steel villas is fast, which will not affect nearby residents and is conducive to civilized construction.

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

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

(5) The comprehensive economic indicators of light steel villas are not higher than those of reinforced concrete structures.

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

(7) Light-steel villas can increase the effective use area compared with brick-concrete structures because the wall thickness of the light-steel structure is small.

(8) Compared with reinforced concrete houses in light steel villas, since the steel of light steel structure can be recycled in the future, but the concrete cannot be recycled, it will definitely be construction waste in the future, causing environmental pressure and it will take 40 years for the concrete to dry completely Therefore, it is easy to cause indoor moisture and humidity, which is not conducive to human health. But the light steel structure does not use concrete at all, so this problem does not exist.

(9) Light steel villas have good seismic performance. Since the seismic activity is left and right and up and down, the light steel structure connected by screws forms a safe and stable box, and the wall will not collapse or the floor will fall and endanger personal safety due to the shaking of the earthquake.

(10) The dry construction method is used in the construction of light steel villas, which will not cause waste of water materials. And save money.

2. The floor structure of the light steel villa

The floor of the light steel villa is composed of cold-formed thin-walled steel frames or composite beams, floor OSB structural panels, supports, connectors, etc. The materials used are oriented strand board, cement fiber board, and plywood. On these light floors, it can bear a load of 316~365 kg per square meter. The weight of the floor structure system of the light steel villa is only 1/4 to 1/6 of the domestic traditional concrete floor system, but the structural height of the floor will be 100~120 mm higher than that of ordinary concrete slabs.

3. Roof system of light steel villa

The light steel villa roof system is composed of roof trusses, structural OSB panels, waterproof layers, and light roof tiles (metal or asphalt tiles). The roof of the light steel structure can have various combinations of appearance. There are also many kinds of materials. Under the premise of guaranteeing the waterproof technology, there are many options for the appearance.

4. Wall structure of light steel villa

The wall of the light steel villa is mainly composed of wall frame columns, wall top beams, wall bottom beams, wall supports, wall panels and connectors. Light steel villas generally use the inner transverse wall as the load-bearing wall of the structure, and the wall columns are C-shaped light steel members. , The wall structure layout of the light steel villa can effectively bear and reliably transmit the vertical load, and the layout is convenient.

5. Building insulation and energy saving technology for light steel villas

In order to ensure the thermal insulation effect of light steel villas, the thermal insulation materials used in the exterior walls and roofs of buildings can be used for a long time and can be thermally insulated. In light steel villas, in addition to filling glass fibers between the wall columns, a layer of thermal insulation material is pasted on the outside of the wall, which effectively cuts off the thermal bridge passing through the wall columns to the outer wall panels; glass fiber is filled in the joists between floors, Reduce the heat transfer through the floor; all interior walls are filled with glass fiber between the wall columns to reduce the heat transfer between the walls.

6. Building Fire Protection Technology

One of the most critical issues for light steel villas is the application of fire protection technology. The fire resistance rating of light steel villas is four. For light steel villas, fireproof gypsum boards are pasted on both sides of the wall and the ceiling of the floor. For ordinary firewalls and household walls, 25.4 mm thick (1 inch) gypsum boards are used for protection to meet the fire protection requirements of one hour. The glass fiber filled between the columns of the body wall and the joists of the floor also plays a positive role in protecting against fire and heat transfer.

7. Building sound insulation technology

In the light steel villa, glass wool is filled between the inner and outer walls and the floor joists, which effectively prevents the audio part transmitted through the air, and the impact sound transmitted through the solid is treated as follows: for the partition wall, two wall columns are used There are two walls with gaps in the middle; for the small keel for fixing the gypsum board for the suspended ceiling, an elastic structure with small slots is used to effectively reduce the solid-borne sound transmission between floors.
