The aluminum alloy structure has inherent material advantages compared with a steel structure, under the same strength, the weight of the aluminum alloy is only 1/3 of steel, and a tensioning chord-supported grid form is adopted, so that the requirement of a large-span space of a building is met. The drawknot rod piece is made of aluminum alloy materials, so that the corrosion resistance is excellent, the maintenance is not needed for the whole life, and the later-stage operation cost is reduced. The chord-supported aluminum alloy grid system can reduce the number of rods, increase the area and the number of the lighting skylight, strengthen the node structure and increase the node rigidity. The system is particularly suitable for large greenhouses, the relative humidity inside the greenhouse garden is high, and the system has higher requirements on corrosion resistance and rust resistance of the structure. In addition, the greenhouse garden has high requirements on the lighting rate and needs to be provided with large-area lighting skylights. The system meets the requirements of light weight, high strength and safety, can form a natural and elegant cloud curve, and expresses light and active architectural language. Overall structure node simple structure, it is convenient to be under construction, satisfies the demand that actual engineering used, accords with the theory of green building, accords with the market demand of large-span, high performance, lightweight and assembled structure, can richen spatial structure's design lectotype, can adapt to different boundary conditions.
