Pipe truss supporting film curtain wall boundary connection device

Abstract

The invention discloses a pipe truss supporting film curtain wall boundary connection device. The pipe truss supporting film curtain wall boundary connection device comprises film bodies, a pipe truss, a fixture, first connection parts and second connection parts, wherein the edges of the film bodies are provided with protruding edge strips, the truss is provided with a chord member and a plurality of web members, the top of the fixture is provided with a first through slot with the inner side being open, the fixture is provided with a plurality of first through holes and second through holeswhich are evenly arranged, symmetrically arranged on the two sides of the chord member of the truss and is connected through the multiple first connection parts and second connection parts, the chordmember is located between the multiple first connection parts and the multiple second connection parts, the edge strips of the film bodies are arranged inside the first through slot in a penetrating manner, and the film bodies stretch out from an opening of the first through slot and extend to the outer side of the fixture at the top of the fixture. By means of the pipe truss supporting film curtain wall boundary connection device, a narrow boundary connection seam is made to exist between the adjacent film bodies, the pipe truss supporting film curtain wall boundary connection device has a better overall appearance decoration effect, furthermore, less film materials can be used when further sealing is performed on the pipe truss supporting film curtain wall boundary connection device, andthe pipe truss supporting film curtain wall boundary connection device has the characteristics of being attractive, convenient, economical and practical.

Description

technical field [0001] The invention relates to the technical field of membrane structure buildings, in particular to a boundary connection device for a membrane curtain wall supported by a pipe truss. Background technique [0002] 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 st...

Problems solved by technology

[0003] 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. When connecting, you can open a hole in the fixture and fix it directly on the secondary steel structure, or you can gradually stretch and fix it through the screw.

These methods can reliably fix the boundary of the membrane body on the support structure, but there are wide boundary seams between adjacent membrane bodies, which will adversely affect the overall appearance and decoration effect of the membrane structure. The same material as the body can be used to further seal the joints, but this requires the use of more membrane materials, which increases the construction cost accordingly
