1.product description：

In western developed countries, the development of dense-rib timber houses has been decades-long, with more than 30% of residential buildings adopting such structures. However, due to extensive eforestation, shortage of timber, mildew of wood itself, Gnawing, people gradually use steel instead of wood structure, and has been widely used. It no longer needs to cut down a large amount of forests and make it more industrialized. It is also an internationally prevailing architectural form. On the surface, the light steel structure of the villa walls and roof modeling rich, flexible door and window design and other advantages. From the internal structure point of view, it is more accurate than wood and brick houses, more space-saving, it has won the praise of domestic and foreign owners.

Light steel villa house flexible design, easy cost control, short construction period, fast return on investment, is the preferred structure of real estate developers room. It is customized according to the design requirements of the owners, suitable for American, Japanese, and modern multi-style villa houses, can be used for private villas, into a piece of residential development, scenic resorts and office, guard, post and other permanent and semi-permanent buildings .

2.Features：
        Light steel villa industrialized production, processing speed, high precision;
        Cold-formed light-weight thin-walled light steel structure system compared with brick-concrete structure: light weight, light foundation, low cost；
        Site does not require large construction machinery, construction speed, a two-story villa of 200 square meters, 6-8 skilled workers can be completed more than 20 days to complete installation;
        Packaging and transportation convenience: product design fully take into account the packaging and shipping links, providing the best way to load a 40-foot container can provide 130-150 square eters;
 The use of a variety of materials to maintain walls and roofs and the breathing of the walls of the houses make living more comfortable and comfortable.
 There is almost no wet operation on site, no pollution to the environment and no seasonal construction restrictions;
 In the premise of meeting various functional requirements, the wall is thinner, which increases the effective use area of the building;
 can be customized according to customer requirements.

3.Technical parameters:
 adapt to the temperature range of -40 degrees - +50 degrees;
 roof live load: 0.5kn / m2 (roof options are: asphalt shingles, steel tiles, cement tiles, etc.);
 snow load: 0-0.85kn / m2;
 Wind load: 0-40m / s;
 Earthquake intensity: 8 degrees above;
 galvanized structure of the useful life: more than 70 years;
 floor load: 2kn / m2-3kn / m2;
 floor load: 2kn / m2-3kn / m2;
 Outer door: metal security door (optional: solid wood doors, broken aluminum doors);
 window: plastic window (optional: broken aluminum bridge);
 Inner door: solid wood composite door;
 The wall structure of 90 c-beam for the column, the wall thickness of 0.8-1.6mm calculated according to design requirements;
 Exterior wall from inside to outside 12mm gypsum board +90 keel (glass filled with) 12osb board + moisture-proof paper + xps insulation layer + exterior (optional finishes: ceramic tile, paint, cement siding and other siding Wait);
 floor structure beam + 18mmosb + carpets (available on the ground floor, floor tiles);
Roof from inside to outside: 9.5mm gypsum board + roof truss (lower chord glass wool) + 12mmosb board + waterproof + asphalt shingles (optional roof: steel tile, cement tile, etc.);

4、Construction Features:
(A) the foundation
Structure itself light, brick and concrete structure is only 1/6, it can significantly reduce the basic cost. Lightweight steel structure can be used as a strip basis.

(B) the wall
Exterior wall thickness is generally between 130-200mm, due to thin walls, light steel houses than the traditional buildings increased by 10% -15% of the use of the area, the room rate of up to 90% of households;Interior space can be flexibly divided, the pipeline can be arranged through the holes reserved in the wall or the ceiling keel, and the concealment is better.Walls and ceilings filled with fiberglass insulation cotton or insulation board, the outer wall can choose to lay extruded insulation board or polyurethane insulation layer, effectively solve the common "cold bridge" phenomenon in the steel structure construction, making the light steel structure house insulation and Sound insulation is much better than traditional masonry and concrete structures.

(Three)roof truss

Roof truss are all bolted, suitable for double slopes, four slopes, hexagonal, anise, Xieshan and other complex roof.

(D) floor
Floor beams can be used c-beam and truss beams, floor beam floor beams can be used c-beam and truss beams, floor beams arranged spacing in accordance with a certain modulus, generally the same spacing with the wall truss, roof keel above the structural plate, the general selection After waterproof, anti-corrosion oriented particleboard (OSB board), the floor filled with insulation cotton. According to a certain modulus, the spacing is generally the same as that of the wall truss. The keel is covered with structural plates. Generally, water-proof and anti-corrosion oriented OSB panels are used, and the floor is filled with insulation cotton.

(Five) structural framework:

Use Q235 or Q345 galvanized steel, galvanized surface can effectively prevent the corrosion of moist air, to prevent the common corrosion of steel common phenomenon, greatly improving the service life of the structure.
