Waterproof joint at membrane ridge cable in cable-membrane structure system and construction method

Abstract

The invention discloses a waterproof joint at a membrane ridge cable in a cable-membrane structure system and a construction method. The waterproof joint comprises a first main membrane material and a second main membrane material, wherein the first main membrane material and the second main membrane material are arranged on both sides of the ridge cable and are made of different materials, and the ends, close to the ridge cable, of the first main membrane material and the second main membrane material are arranged in containing grooves of a first membrane material clamp and a second membrane material clamp in a penetrating mode through side ropes correspondingly, the first membrane material clamp and the second membrane material clamp are connected with the ridge cable through a V-shaped clamp and a U-shaped clamp correspondingly, an L-shaped clamping plate and a pressing plate are arranged on the outer side of a side arm of the upper part of the U-shaped clamp, a first waterproof membrane and a second waterproof membrane cover the outer sides of the tops of the first main membrane material and the second main membrane material correspondingly, the reverse ends of the first waterproof membrane and the second waterproof membrane are welded to the first main membrane material and the second main membrane material correspondingly, and the opposite ends of the first waterproof membrane and the second waterproof membrane extend into a gap between the L-shaped clamping plate and the pressing plate and are fixed through self-tapping screws. According to the waterproof joint, the problem of leakage caused by welding of different types of waterproof membrane materials and the main membrane material is avoided, the connection is reliable, the waterproof performance is good, the shape is attractive, and the lighting performance is good.

Description

technical field [0001] The invention relates to the technical field of architectural cable-membrane structure design, in particular to a waterproof node at a membrane ridge cord in a cable-membrane structure system and a construction method. Background technique [0002] The cable-net-membrane structure is a new type of space structure that is developing rapidly at present. It is a highly efficient tension integration system that can give full play to the strength of the steel cables and the space function of the tensioned overall structure. Tensile membrane structure is the most common form of cable mesh membrane structure, and it is the representative and essence of cable mesh membrane architecture. It forms a stable curved surface to cover the building space through the joint force of steel cables and membrane materials, and has a high degree of physical plasticity. And structural flexibility, that is, by applying a certain pre-tension to the inside of the membrane materi...

Problems solved by technology

These structures are often high-altitude and long-span steel structures, which not only add highlights to the building, but also bring great difficulties to on-site construction.
