What are the wall materials of light steel villas? -wellcamp light steel villa manufacturers
The exterior wall of the light steel structure villa is divided into an inner wall and an exterior wall. The main raw materials of the behavior are all light steel keels, and 100 mm glass fiber wool is laid in the gaps of the keel columns. Exterior wall scheme 1: (take the light steel keel column as the boundary)——Outward one by one: 12mm OSB board, one-way breathing paper, metal carved board——Inward one by one: 12mm thick plasterboard. Exterior wall plan 2: (with light steel keel column as the boundary), there are fixed parts——Outward one by one: 12mm OSB board, one-way breathing paper, extruded plastic board, metal carved board——Inward one by one: 12mm thick plasterboard. Interior wall scheme: It is bounded by light steel keel columns, with thick gypsum boards or cement boards on both sides. At this stage, there are also many ways to do the exterior walls of light steel structure houses on the market: 1. Double-sided OSB board + thermal insulation and sound insulation cotton (glass fiber cotton) 2. Double-sided high fiber cement board + thermal insulation and sound insulation cotton (glass Fiber cotton) 3. Double-sided high cement board + cast-in-place foam concrete external wall structure features: there are four types of external wall panels, internal wall panels, partition wall panels, and thermal insulation blocks. Different exterior walls can be combined according to the climatic temperature of different regions. In cold areas, a composite outer wall with thermal insulation and heat insulation is combined to ensure that indoor heat is not absorbed or leaked by the outer wall, and the actual effect of environmental protection and energy saving is 80%. In other words, only 1/5 of the normal engineering building is required Energy consumption can achieve indoor insulation requirements. The floor of the light steel structure villa is composed of cold-formed thin-walled steel frames or composite beams, floor OSB structural plates, supports, connectors, etc. The raw materials used are oriented strand board, cement fiberboard, and its plywood. On those light floors, it can carry loads of 316 to 365Kg per square meter. The total weight of the standard system of floor structure characteristics of light steel structure villas is only one-fourth to one-sixth of the standard system of traditional concrete floor slabs in mainland China, but the relative height of the floor structure will be 100% higher than that of ordinary concrete slabs. ~120mm. Lightweight steel structures are usually made of ultra-light raw materials, that is, newer types of engineering building ecological boards, which are generally used: OSB boards, extruded plastic boards, asphalt coils, asphalt shingles, etc. for roofs. External wall OSB board, breathing paper, cement fiber hanging board.
