Problems solved by technology

Since this system is tensioned by steel cables, the steel cables are flexible in the direction of compression, so it cannot solve the overall stiffness problem of the steel canopy, and it does not contribute to the overall stiffness of the roof
Therefore, it is necessary to add special measures to improve the overall rigidity of the roof, such as adding connection trusses, etc., which not only increases the cost and construction process, but also cannot solve the integrity of the unit membrane structure

Abstract

The invention provides a steel-membrane space composite structure unit based on rigid support and a membrane tightening method thereof. The structure unit comprises a membrane cap unit and a membrane unit; the membrane cap unit is connected with the membrane unit; the membrane cap unit comprises a supporting unit and a jacking unit; the jacking unit comprises a loop jacking ring and a jacking device; and the loop jacking ring tensions or adjusts membrane tension of the membrane unit through movement of the jacking device. The supporting unit provides rigid support for the membrane structure, a steel-membrane space combination unit is formed after the membrane material is tensioned, the overall rigidity of the structure can be improved, and overall deformation of the structure can be better coordinated.

Description

technical field [0001] The present application relates to a steel-membrane space composite structure system and its construction method, in particular to the steel-membrane space composite unit structure of building roofs and its rigid support stretching membrane technology. Background technique [0002] Membrane structures usually use high-strength flexible film materials and auxiliary structures to generate a certain pre-tensioning stress inside in a certain way, and form a certain spatial shape under stress control as a covering structure or building body. [0003] In the membrane structure design of the space steel structure canopy, the tapered membrane tensioning system usually adopts the "flying column" flexible cable tensioning system of the cable tensioning membrane. Since this system is tensioned by steel cables, the steel cables are flexible in the compression direction, so it cannot solve the overall stiffness problem of the steel canopy, and it does not contribut...
