Detachable large-span pre-stressed integral tension awning and construction method thereof

Abstract

The invention discloses a detachable large-span pre-stressed integral tension awning and a construction method thereof. The awning comprises more than two integral tension cable truss units, pin type connecting pieces and membranes, wherein the more than two integral tension cable truss units are arranged in parallel; the pin type connecting pieces are arranged between two adjacent integral tension cable truss units; the membranes are paved between valley cables and ridge cables of the integral tension cable truss units; each of the integral tension cable truss units consists of a group of ridge cables, two groups of valley cables, support trusses, end part outer cables, inner oblique cables, end part oblique columns and oblique column upper horizontal supports; and each of the pin type connecting pieces consists of two semispherical joints, two cable clamping joints, pin shafts and connecting plates. The trusses can form a stable structural system, and can be combined freely; the detachable large-span pre-stressed integral tension awning has the advantages of high overall stability and convenience in assembling and disassembling, and can be applied to remote reconstruction of industrial material storing awnings, mining of open pit quarries and coal yards and large-area open archaeology operation, and can be taken as a temporary disaster relief resident settlement area, a hospital in wartime, a conventional article warehouse in wartime; a larger-span structure can be realized.

Description

technical field [0001] The invention relates to a large-span building canopy structure and a construction method thereof. Background technique [0002] At this stage, the national environmental protection policy requires that open-air stockyards and coal yards must be closed, and some steel mills and power plants in major cities may be relocated and rebuilt under pressure from environmental protection. Therefore, there is an urgent need for a building structure system that can be disassembled and rebuilt while realizing a super-large span. [0003] For the mining of open-pit coal yards and mines, large-area open-pit archaeological sites, etc., require a large-span detachable and off-site rebuildable building. The conventional long-span steel structure adopts rigid structures such as steel trusses and steel grids, and the connections are welded. As a permanent building, there is no possibility of demolition and reconstruction in different places. Most of the existing buildi...
