The Parameter of Light steel Villa House

Light steel villa, also known as light steel structure house, its main material is light steel keel synthesized by hot-dip galvanized steel strip and cold-rolled technology. After accurate calculation and support and combination of accessories, it is reasonable Bearing capacity.

The technology and product configuration of light steel structure are very mature, and the degree of industrialization is high. It is the crystallization of the development of construction technology and building materials industry in North America in the past 100 years. The galvanized steel sheet used in the building structure has excellent corrosion resistance and durability.

The seismic performance of light steel structure is far superior to traditional concrete and brick-concrete houses. At the same time, due to the light weight of the light steel structure, the unit area weight is only equivalent to 1/4 of the weight of the brick-concrete structure of the same area, so its foundation treatment is simple and suitable for most geological conditions. Steel structure houses no longer worry about termite hazards like wooden structure houses. Because the steel materials used in the structure are all factory-processed, the structural accuracy of the light steel structure villa is quite high. The structural system of a villa is composed of tens of thousands of components, and the average error of each component is less than 2 mm, which ensures The quality of the house is beyond the reach of traditional construction methods. In addition, the cold-formed thin-walled light steel structure is warm in winter and cool in summer, moisture-proof and mildew-proof compared with traditional brick-concrete buildings. It has many advantages, such as quick installation, rich shape, large effective area, low carbon and environmental protection. The construction technology of light steel structure low-rise civil residential buildings is in line with the country's industrial orientation to the construction industry, and has been supported by relevant government departments at all levels in policy and technology. The structural steel frames and bolts are all high-galvanized anti-corrosion processes (galvanized 180g/ ㎡ or more, special up to 350g/㎡), the main structure meets the 50-year structural safety design. Walls, roofs, and floors can not only transmit vertical loads to the foundation, the structure forms a flexible connection of nodes through screw connections, which can resist lateral loads such as large winds and earthquakes.

Strength: The cold-formed thin-walled steel structure has quite high strength and rigidity. The main reason is the joint action and compound action of the components. The joint action of the components can provide a variety of ways for load transfer, and the compound action of the components means that when the cladding panel (Ou Song board) and the steel structure frame are connected together, the cladding panel and the steel structure frame can bear and transmit together The load acting on the structure. Strong adaptability and durability

The cold-formed thin-walled steel structure house system is suitable for various environments, such as areas with large temperature changes, rainy, snowy and windy areas, or areas with high humidity, earthquake influence and uneven terrain (such as: islands, flat grounds) , Slopes, mountains, deserts, etc.). In addition, it can also be designed and constructed with various interior and exterior decorations to ensure proper durability in areas with high humidity and strong winds.

Characteristics of breathing paper

It uses a special new polymer material. The surface of the material has an extremely fine microporous structure. Since the minimum diameter of water droplets is about 0.02 mm, and the diameter of water vapor molecules is only 0.0000004 mm, there is a huge difference in diameter between the two, and the diffusion is based on the concentration gradient difference. The principle is that water vapor can freely pass through the micropores, while liquid water and water droplets cannot pass through the breathing paper material due to their surface tension. Therefore, the breathing paper has excellent waterproof and vapor permeability properties.

Breathing paper is mainly used for the foundation of building protection such as wooden structure and steel structure. Breathing paper has excellent waterproof and vapor permeability.
