Steel Structure Villa Parameters
1. Performance parameters of light steel villa: (1) earthquake resistance: it can resist earthquakes of magnitude 9, which is suitable for areas with seismic intensity level 8 or above. (2) wind resistance: can resist the hurricane of 70m/s, and the wind resistance level is above level 12; (3)...
1. Performance parameters of light steel villa:
(1) earthquake resistance: it can resist earthquakes of magnitude 9, which is suitable for areas with seismic intensity level 8 or above.
(2) wind resistance: can resist the hurricane of 70m/s, and the wind resistance level is above level 12;
(3) durability: the main structure can last more than 70 years;
(4) occupancy rate: compared with traditional buildings, light steel integrated houses can increase the use area by 5% to 13%;
(5) fire resistance: the fire-resistant time can be up to 1-4 hours according to different design;
(6) noise insulation: the sound insulation of the external wall can reach 65dB, and the sound insulation of the inner wall can reach 455dB;
(7) heat preservation: 200 mm thick composite wall, the thermal resistance of 3.2 ㎡ K/W, 11 times that of brick wall thickness;
(8) environmental protection: the steel structure material can be recycled 100%, and other supporting materials can be recycled for the most part;
(9) energy conservation: the use of new building materials with thermal insulation performance is about 65% less than that of traditional buildings;
(10) construction period: the assembling operation of light steel house is simple and fast, which is two thirds shorter than the traditional construction period.
2. Characteristics of light steel villa:
(1) stable structure;
(2) low cost;
(3) the span of interior space of light steel structure villa is larger than that of concrete building;
(4) short duration, much faster than conventional buildings.
3. Compared with traditional houses, light steel villas have their outstanding advantages:
(1) the light steel structure of light steel villa has high degree of mechanization degree and high degree of commercialization.
(2) the site construction speed of light steel villa is fast, mainly for dry operation, which is conducive to civilized construction.
(3) steel structure building of light steel villa is environmentally sustainable development product.
(4) light steel villa has light weight and good anti-seismic performance.
(5) the comprehensive economic index of light steel villa is not higher than that of reinforced concrete structure.
(6) light steel villas can avoid the waste of resources caused by the use of clay bricks compared with brick houses.
(7) light steel villa, because the wall thickness of the light steel structure is small, it can increase the effective use area than the masonry structure;
(8) of the light steel villa compared with reinforced concrete house, because of the light steel structure steel can be recycled, but cannot be recycled concrete, after must be construction waste and environmental pressure and concrete to 40 years to all dry, so easy to cause indoor moisture, moisture, is not conducive to human health. But the lightweight steel structure is completely free of concrete and therefore does not exist.
(9) the anti-seismic performance of light steel villa is good. Due to earthquake activity for the left and right and up and down, so use screw together the light steel structure formed a box, security and stability will not appear because of the earthquake shaking collapsed wall or floor off the endanger personal safety.
(10) the construction of light steel villa adopts dry construction method, which will not cause waste of water information. And it saves money.
