Abstract

The invention discloses a high-space large-span broken-line-shaped cable membrane structure and a construction method thereof. The cable membrane structure comprises an outer ring beam and a central inverted-cone-shaped truss, wherein three circles of a ridge cable, a valley cable and a bearing cable are arranged between the outer ring beam and the central inverted-cone-shaped truss from top to bottom to form a stable stress system, the ridge cable and the valley cable are each symmetrical about the axis of the central inverted-cone-shaped truss, PTFE membrane materials, ETFE membrane materials and hyperbolic ETFE membrane materials cover the ridge cable, the valley cable and the central inverted-cone-shaped truss and are subjected to waterproof design, and the whole covered membrane is distributed in a broken line shape. During construction, the outer ring beam is poured firstly, then the center inverted-cone-shaped truss is manufactured, the steel cables are laid, lifting cables and auxiliary balance cables are selected in sequence, finally synchronous lifting and tensioning construction is conducted, and membrane materials are installed after the whole structure is tensioned and formed. The structure is attractive, a tower or a supporting frame does not need to be erected at the position of the floor, the problems that the site is narrow, the building ground bearing capacity is limited, and the hoisting height is too high are effectively solved, and meanwhile the problems that cable membrane construction is large in safety risk, long in construction period and high in measure cost are solved.

Description

technical field [0001] The invention relates to the technical field of cable-membrane structure design, in particular to a high-space and large-span zigzag cable-membrane structure and a construction method thereof. Background technique [0002] The cable-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 cable and the spatial effect of the tensioned overall structure. The force-bearing form stabilizes the curved surface to cover the building space, which has a high degree of physical plasticity and structural flexibility; the traditional cable-membrane structure is usually a single cable system or a double-layer cable system, with a single shape; in the actual construction process, due to different site conditions, etc., Cable-membrane structures have different forms, especially for the construction of high-space and large-span cab...
