Application of light steel structure building

Lightweight floor systems

Lightweight floor systems consist of C floor joists and spread light steel sheet in the joists.The average span of the grid is 3.6 meters to 4.8 meters, the grid height is 254 mm (the maximum span of the grid is 11 meters), the grid spacing is 600 mm.The floor has three ways, respectively: Floor there are three ways, respectively: High density wood fiber cement board; A lightweight aggregate concrete with 20 mm of the full spread sheet of steel sheet; Full spread oriented wood fiber board or high density laminated plywood. In the light on the floor load per square meter 316 ~ 365 kg.

Vertical wall structure

Vertical wall structure in general will cross wall as bearing wall structure, wall columns is the C shaped steel member, the wall thickness according to by the load and decide, usually 0.84 to 2 mm, wall and column spacing 400m ~ 600 mm. The lower end of the wall column is the bottom of the groove of the U shaped opening upward, the upper end of the wall column is the top of the U shaped opening downward,joists are fixed on the groove beam sides. In order to improve the stability of the wall columns, general wall column height range with three steel brace.This wall structure can effectively bear and transmit the vertical load, and the layout is convenient, but the wall structure can not bear the horizontal load.

Building insulation and energy saving technology

Light steel housing system in the United States on the thermal insulation energy-saving technology very seriously, for the wall to ensure the heat insulation effect is reached, general besides the in wall of the wall between the columns filled with glass fiber, sticking a layer of insulation materials on the outside of the wall, effectively cut off the through the wall to the column wall board with thermal bridge; between the floors of the grid filled with glass fiber, reducing heat transfer through the floor; it is filled with glass fiber between all the interior wall columns to reduce the heat transfer between the wall.

Building fire protection technology

The most important problem for the light steel structure building is the application of fire prevention technology.Stick fireproof gypsum board in the ceiling of both sides of the wall and floor,for the use of 25.4 mm thick ordinary firewall and wall (1 inch) gypsum board protection, in order to achieve the requirements of Fire 1 hours. In addition, the glass fiber filled between wall columns and floor joists also played a positive role to prevent fire and heat transfer .

Building sound insulation technology

The inner and outer walls and floor joists of light steel structure building filled with glass wool, can effectively prevent the audio part spread through the air. And for the impact of the transmission of solid, in the United States of multi-storey steel residential, made the following structural treatment: The two wall of the wall is composed of two wall with middle space;and for the ceiling of the fixed plate of the small keel, with a small groove of the elastic structure to effectively reduce the floor of the solid sound transmission.
