Membrane structure is a membrane body made of high-strength flexible membrane material. It is a curved surface structure formed by tensioning and fixing on a rigid support member. According to different support methods, it can be divided into integral tension type, skeleton support type, and cable structure. Department of support, air support and other types. As a new type of building material, flexible membrane can play the role of enclosure, decoration, sunshade, heat preservation or sound absorption at the same time. It has the characteristics of light structure, rich shape, stable performance, energy saving and environmental protection. Using membrane structure as building curtain wall has Broad application development space. The membrane structure curtain wall mainly adopts the form of skeleton-supported membrane structure. After the membrane body is stretched, the edge of the membrane body is fixed on the rigid support member.

At present, one technology for connecting the edge of the membrane body and the supporting structure is the splint fixing method. First, holes are made on the edge of the splint and the membrane body, and then the edge of the membrane body is directly crimped and fixed on the secondary steel structure with bolts. This method requires the use of fixtures The membrane body is stretched in place at one time, and it needs to be perforated on the membrane body, which is relatively easy to cause damage to the membrane body during installation; at present, another technology for connecting the edge of the membrane body and the supporting structure is the clamp connection method, which is first connected at the edge of the membrane body Install the fixture, and then use bolts or screws to connect and fix the fixture on the secondary steel structure.
