According to the climate conditions and seismic fortifications of the area where Mengxi Company is located, the main forms of the structure are: rough stone base steel ç ¼ independent basic steel truss truss; rough stone base composite brick wall column truss; Steel truss independent basic door type light steel rigid frame; retaining structure mainly consists of masonry and color steel sandwich panels; roof part: large roof slab, thin web; gantry light steel frame color plate, triangle Steel roof truss and other forms. After several demonstrations, the wall column is selected between the traditional masonry envelope structure and the color plate; the roof is selected between the grid color plate and the light steel color plate, mainly based on the long construction period of the large roof slab and the thin web beam, and the roof surface The waterproof house has a large maintenance capacity. At present, the price is similar to that of the new structure, and the appearance is dull. It has rarely been seen in Zhangjiagang Economic and Technological Development Zone, Shanghai Zhangjiang Industrial Park and Tianjin Development Zone. In addition to the above shortcomings, there are also inconveniences such as inconvenience in modification and dismantling, and poor internal appearance. Color plates or sandwich insulation boards are still new materials in China, especially in the central and western regions. They have been in coastal developed areas for nearly 20 years. In the early days, it was mainly a full set of foreign imports, mainly used in large-span warehouses and poorly-developed coastal industrial plants along the Yangtze River. In recent years, it has been widely used in various types of buildings. Its main features are beautiful appearance, light weight, integrated thermal insulation and waterproof function, fast construction speed, small daily maintenance, and can be processed according to the needs of the owners. Most of the construction products are manufactured in the factory, and the site installation is almost no. Affected by the climate, it has achieved large-scale standard production of building products. Due to the high price in previous years, the scope of use has been limited. In recent years, it has been widely promoted and applied, and the price has gradually been recognized by various industries. The light steel structure has been used for more than 50 years in foreign countries. Like the color steel plate, it has been used in the most mobile departments such as the military and field operations. It is characterized by light weight, small amount of construction, transportation and disassembly, and can be large or small according to requirements. The height, span and length can be large or small. The combination with the color steel retaining plate can provide beautiful and comfortable and clean for the owners with large mobility in the field. Work, production, living space. Now the country has also been promoted to the business community. The main features are light weight, high standardization of components, and can be manufactured in large quantities in the factory. In recent years, with a large number of applications, the span can reach nearly 100 meters. The disadvantage is that the overall rigidity is small, it is a flexible structure, and it is resistant to wind, snow, snow and other uneven load capacity, and the ability to withstand sudden load such as collision is poor.
