The advantages and disadvantages of prefabricated light steel villas?

Advantages of light steel villas:

(1) The production of light steel structural accessories for light steel villas is highly factory-based and mechanized, and has a high degree of commercialization.

(2) The on-site construction of light steel villas is fast and mainly dry work, which is conducive to civilized construction.

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

(4) Light steel villas have light weight and good earthquake resistance.

(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 using clay-fired bricks

(7) Light steel villas have light steel structure walls The thickness of the body is small, which can increase the effective use area than the brick-concrete structure;

(8) Compared with reinforced concrete houses, the steel of the light steel structure can be recycled in the future, but the concrete cannot be recycled After use, it will definitely become construction waste, causing environmental pressure. Moreover, it takes 40 years for concrete to dry completely, so it is easy to cause indoor moisture and humidity, which is not good for human health. However, light steel structures do not use concrete at all, so this problem does not exist.

(9) Light steel villas have good seismic resistance. Since the earthquake moves left and right and up and down, the light steel structure connected with screws forms a safe and stable box, which will not cause the wall to collapse or the floor to fall due to the shaking of the earthquake, endangering personal safety.

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

Disadvantages

1. The cost may be slightly expensive

2. Heavy reliance on industrial supporting facilities, such as prefabricated wall panels, roof panels, wall insulation materials, Fireproof materials. In the currently popular concrete and masonry structural forms in China, the walls are basically constructed by on-site wet masonry, while light steel structures require dry prefabricated wall panels.

3. It requires matching interior decoration materials, devices, and methods. For example, the method of installing water heaters, air conditioners, and picture frames on prefabricated wall panels is still very different from the current method of installing on masonry walls. Another example is the waterproofing and sound insulation methods of the profiled steel plate floor.

4. Regular inspection and maintenance are required, because the durability of steel is still not as good as concrete, and it is not as "violent" as concrete
