Light steel villa, also known as light steel structure house, its main material is light steel keel synthesized by hot-dip galvanized aluminum steel strip through cold rolling technology.
The aluminum-zinc alloy structure of the galvanized steel sheet is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal. So as to form a strong and effective barrier to prevent the penetration of corrosive factors.
Light steel characteristics
1. Corrosion resistance:
The corrosion resistance of "55% aluminum-zinc steel coil" comes from the barrier layer protection function of aluminum and the sacrificial protection function of zinc. When zinc is used for sacrificial protection on the cut edges, scratches, and scratches of the coating, aluminum forms an insoluble oxide layer and exerts a barrier protection function. The aluminum-zinc alloy steel coil has been subjected to outdoor exposure tests for more than 20 years in various atmospheric environments, and it is confirmed that the cutting edge protection function of 55% aluminum-zinc steel plate is better than that of galvanized steel plate and 5% aluminum-zinc steel plate. good.
2. Heat resistance:
The heat resistance of 55% aluminum-zinc alloy steel plate is better than that of galvanized steel plate, which is similar to the high temperature oxidation resistance of aluminum-plated steel plate. The aluminum-zinc alloy steel plate can be used in a high temperature environment up to 315 degrees.
3. Reflectivity:
The 55% aluminum-zinc alloy steel plate has a high degree of reflectivity, making it a heat-resistant barrier; the heat reflectivity of the aluminum-zinc alloy steel plate is almost twice that of the galvanized steel plate, so it can serve as a roof and inlay without painting. The board can also achieve energy-saving effects.
4. Paintability:
Due to the excellent adhesion between the zinc layer of the galvanized steel sheet and the paint, it can be painted without pretreatment and weathering when used as a sign board for general purposes; while the galvanized steel sheet needs weathering and pretreatment .
Basic composition
Light steel villa system structure
The light steel wall structure system is composed of light steel multi-ribbed beams and columns and the maintenance structure. It has excellent physical performance indicators, short construction period, and good insulation effect. It is a new type of green, energy-saving and environmentally friendly building structure system.
1. Basic system
The light weight of the light steel structure house is light, only about one-fifth of the brick-concrete structure house, and about one-eighth of the reinforced concrete structure house, so it can greatly reduce the cost of foundation construction. The light steel structure house foundation generally adopts the strip foundation. Can.
① The light steel structure is light in weight, which can greatly reduce the cost of basic engineering;
② The basic moisture-proof design can effectively prevent the intrusion of moisture and harmful gases;
③ Reasonable anchoring method to ensure the reliable connection between the foundation and the main body.
2. Wall system
The external wall system is generally between 120-200mm. Due to the light and thin wall, light steel structure houses increase the actual use area by about 10%-15% compared with traditional houses, and increase the indoor use area by more than 90% compared with traditional houses. Can be flexibly separated. The pipelines can be arranged in the holes reserved for the walls, floors and roof components, which has good concealment and is more beautiful.
① The wall is filled with glass fiber cotton, which has good heat preservation, heat insulation and sound insulation performance;
② The breathable paper is waterproof and breathable, which can effectively adjust the indoor air humidity, make living more comfortable, and effectively prevent the growth of mold inside the wall;
③ The pipeline is buried in the wall and does not occupy indoor space.
3. Floor system
The floor is made of high-strength hot-dip galvanized C-shaped and U-shaped light steel components. The floor beams are arranged in accordance with the standard modulus and evenly spaced and ribbed. The floor beams are covered with structural plates that have been strictly moisture-proof and anti-corrosion to form a strong earthquake resistance. Floor system.
① Combined structure of structural slab and floor steel beam, strong and stable;
② Various water and electricity pipelines are hidden in the floor structure and do not occupy the height of the building;
③ Filling glass fiber wool in the interlayer, the effect of heat preservation, heat insulation, sound absorption and sound insulation is remarkable.
4. Roofing system
The roof truss is assembled from various light steel components. Generally, there are triangular roof truss and T-shaped roof truss, which can easily and flexibly realize various complex roof shapes. Generally, the roof adopts colorful asphalt shingles, which has good waterproof performance, and highlights the beauty and quality.
① The composite roof has the functions of rainproof, weatherproof, heat insulation, etc., which can realize a variety of shapes;
② Ventilation circulation design keeps the air fresh at all times.
5. Structural components
All structural components are made of high-strength galvanized steel to ensure the service life of the house. All structural components are cold-formed by the factory's precision machinery assembly line, and the dimensional accuracy is in millimeters, which is unmatched by other structures.
