Description

The company has introduced the light steel villa system from North America, Australia and other regions to adapt to the growing demand for light steel villa system, which has the following main features: wall load-carrying system structure is constituted by small-spacing cold-pressing thin steel joists; new type materials with characteristics such as light weight, high strength and good thermal insulation and fire resistance are used for wall plates and floors; standardized and normalized building fittings, etc. The exterior wall consists of exterior wall plate, water barrier, structural exterior plate, light steel joist, heat insulator, and interior veneer. Exterior wall plates include: metal clapboard, vinyl clapboard, wooden siding clapboard, and wooden tongued and grooved clapboard, all of which can meet the requirements of various fa?ade renderings. The interior wall uses light steel joist plasterboard insulated partitions with maximum fire resistance up to 2 hours; sound insulation up to *3DB; thermal resistance rating of insulating cotton inside wall between R**-R*0; unilateral air-permeated and water-repellent moist-proof paper for exterior wall&#**9;s water barrier. The floor system of typical light steel villa system mainly consists of joist, structural panel and suspension ceiling. The joist uses cold-fromed& thin-wall steels as load-bearing members; the structural panel is OSB oriented flakeboard; the suspension ceiling is light steel joist plasterboard, and light steel villas generally have sloping roofs, basic structural forms of which are: Inclined girder, structural panel, water barrier and thermal insulator, and veneer. Boards used for roof veneers include composite roofing veneers, color embossed clamped tiles, color corrugated tiles, metal joint-lock sheets and color fiberglass tiles, etc. with diversified colors, shapes and strong bonding and leakage-proofing performance. Compared with brick-concrete structure, light steel villa has more dynamic and sleek shapes with better thermal insulation performance, and wall surfacing materials of different textures can create many architectural styles; compared with wooden structure, light steel villa is more cost-effective. Materials for light steel villa are mostly environmentally friendly green building products. In addition, small section size and light dead weight of cold pressing steel joist frame has 5~8% more construction area use ratio than traditional structures, so basic cost is reduced. One point more worth noting is that light steel villa system requires simple construction process and project term — in construction of one *-storied light weight villa with an area of approximately **0㎡ , project term of main structure is only 1 month if there are 5 construction workers for construction.
