Steel structure engineering

Steel structure engineering
The floor of the light steel structure is composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, support and connecting parts. The materials used are oriented strand board, cement fiberboard, and plywood. In the light of floor load per square meter 316 ~ 365 kg. Concrete floor system weight floor structure system building Matt light steel structure residential only domestic traditional 1/4 to 1/6, but the structure of the floor height than ordinary concrete in high 100 ~ 120 mm.
The roof system of light steel structure
The roof system of light steel structure residence is composed of roof truss, OSB panel, waterproof layer and light roof tile (metal or asphalt tile). Maite building light steel structure roofing, appearance can have a variety of combinations. There are many kinds of materials. In ensuring the premise of waterproof technology, the appearance of a number of options.
Two, light steel structure of the wall structure
The main body of the light steel structure residence is composed of the wall column, the top wall, the bottom wall beam, the wall support, the wall plate and the connecting piece. Maite building light steel structure housing will generally be within the cross wall structure as load-bearing walls, wall columns for C shaped steel member, the wall thickness according to the load and decide, usually 0.84 ~ 2 mm, the wall column spacing is generally 400 to 600 mm, Maite building light steel structure housing the wall structure arrangement, can effective and reliable transmission under vertical load, and convenient arrangement, but the mitre building light steel structure residential wall structure cannot bear horizontal load.
Three, light steel structure of building insulation energy saving technology
Light steel structure in order to ensure the insulation effect, in the building's exterior walls and roofing used in insulation materials can be used for a long time and can heat insulation. Maite building light steel structure residential general in addition to glass fiber filled in the wall between the column wall, put a layer of thermal insulation materials in the wall, through the effective partition wall column wall panels to bridge between floors; shelf filled with glass fiber grid, reduce the heat transfer through the wall between the floors; all inner wall column are filled with glass fiber, reduce the heat transfer between the wall.
Four. Building fire prevention technology
Light steel structure is one of the most critical problem is the application of fire prevention technology, building fire resistance rating Matt light steel structure residential is four. Mitre building light steel structure residential at the ceiling on both sides of the wall and the floor of the fireproof gypsum board, with 25.4 mm thick ordinary firewall and wall (1 inches) of gypsum board protection, in order to reach the fire for 1 hours, in addition to the wall wall between the columns and floor for glass fiber filled transfer gate also played an active role in the protection of the fire and heat.
Five. Building sound insulation technology
The light steel structure in the inner and outer walls and floor joists are filled between the glass wool, effectively preventing the spread through the air for the audio part, through solid impact sound transmission, as follows: the structure of household wall with two wall column form two wall with intermediate gap; while the fixed gypsum board ceiling in use the small keel, with elastic structure with a small groove to effectively reduce the solid sound propagation between the floors.
