What are the characteristics of Chongqing light steel keel villa

Chongqing light steel keel villa is a high-quality continuous galvanized sheet, a building metal frame rolled by cold bending technology. It can be used for non-load-bearing wall and roof decoration of lightweight gypsum board such as gypsum board, decorative gypsum board, etc. It is suitable for decoration of various building roofs, building interior and exterior walls, and SCA basic materials. The ceiling has ceiling joists and partition joists according to the usage. There are V, C, T and L keels in cross section. In view of the difficulty of outdoor heat insulation of light steel keel villas in Chongqing, indoor heat preservation is mainly used. Double insulation measures should be taken for the roof and ceiling, that is, a direct insulation layer is placed under the roof to minimize the thermal radiation effect of the roof sunlight. Then stick the top of the ceiling tightly to the ceiling, allowing the insulation to act as a direct insulation. The external wall insulation is similar to the roof insulation, and the insulation cotton is densely distributed between the steel structure and the wall of the light steel keel gypsum board. The wall material is made of aerated concrete blocks with better thermal insulation performance, which plays a role in thermal insulation. In order to avoid the cold bridge effect of the steel structure, indoor condensation occurs. In this project, a layer of thermal insulation paper is used to prevent moisture and thermal insulation between the plasterboard and the ceiling plasterboard. When laying, it must be ensured that the insulating paper must be closed and the width of 100mm must be guaranteed. In addition, considering that in the steel structure column, water immersion in the concrete foundation will corrode the column foot, a polyethylene plastic film is used as a moisture-proof measure between the foundation concrete and the column foot. Chongqing light steel keel villa is a new type of structural system developed by Canada Intel Land Bank 1048577 and T.NATA, and has also been applied in Canada, the United States, Australia and other countries. The light steel keel structural system is a dense beam and dense column light steel structure. The section of the beam and column is a truss structure composed of thin-walled cold-formed galvanized square steel pipes and V-shaped nodes. The thickness of thin-walled cold-formed galvanized steel pipe and V-connector is between (1~2)0, and the columns are arranged around the house to form a wall skeleton. The height of the child is the same as the height of the layer. The width of U is 240 and 370, which is in line with the current building modulus in our country. All components are connected via self-tapping screws via an adjustable clutch screwdriver. The structure of the light steel keel structure can be freely arranged on the building and can be freely assembled on the plane to form an ideal opening and depth. The middle and middle distance of the truss column is about 600. Compared with reinforced concrete houses, Chongqing light steel keel villas can be recycled because steel structures can be recycled, but concrete cannot be recycled. It must be construction waste. It causes environmental stress and concrete dries for 40 years. Therefore, it is easy to cause indoor humidity and humidity, which is not conducive to human health. But light steel structures do not use concrete at all, so there is no such problem.
