Background technique

Aluminum alloy materials have many advantages such as light weight, high strength, good corrosion resistance, processing performance, high reflectivity and beautiful color. Aluminum alloy can obtain a variety of profiles with complex cross-sections through extrusion molding technology, so it is more and more used in the field of building structures, especially suitable for botanical gardens, greenhouses, swimming pools, ice rinks and petrochemical storage tanks, which have high anti-corrosion requirements. building. Because the free-form surface structure is not limited to the analytical expression of the traditional surface, the surface form is more rich in undulations, not only has more visual impact, but also the structural force is more reasonable. Therefore, in the field of long-span spatial structures, free-form surface structures have received increasing attention. At present, the most widely used and researched joints in aluminum alloy single-layer reticulated shell structures are plate joints designed by Temcor Corporation of the United States. The poor universality of such joints and the single joint form have become a major reason for restricting the development of aluminum alloy reticulated shell structures. Therefore, it is necessary to develop new joints that are suitable for the properties of aluminum alloy materials, have clear and reasonable force transmission methods, and are convenient for construction.
