Circular awning with cable dome and spatial steel truss being combined and construction method of circular awning

Abstract

The invention relates to a circular awning with a cable dome and a spatial steel truss being combined and a construction method of the circular awning. The circular awning comprises an awning roof and a main body; the circular awning is an approximately spherical segment surface; the awning roof is of a cable dome structure; the main body is of a spatial steel truss structure; the bottom end of the cable dome is fixedly connected with the top end of the spatial steel truss structure. The spatial steel truss structure comprises at least one layer of weft curved beam which is a polygonal spatial steel truss. The spatial steel truss structure comprises at least two layers of weft curved beams and radial curved pillars; the radial curved pillars are connected with each layer of weft curved beams, and every two adjacent radial curved pillars are connected through weft pull rods which are arranged at intervals according to fixed latitudes. The circular awning disclosed by the invention combines tensile and rigid structures, integrates inward tension of the tensile structure and outward thrust of the spatial steel truss structure, and realizes self-balance of inside and outside stresses; the stress of an arched steel structure is reduced, the integral structural stability is better, and meanwhile, the horizontal thrust of the lower part of the steel truss structure and a support is reduced, the maintenance cost of late-stage anticorrosion is reduced, and the construction efficiency is high.

Description

technical field [0001] The invention relates to a novel structural system combining a cable and a steel structure, in particular to a combined structure of a cable dome and a space steel truss and a construction method thereof. Background technique [0002] The existing arched space steel truss structure has clear stress, so it is widely used in industrial buildings such as long-span workshops and warehouses. The arch space steel truss structure needs to be stressed, the larger the span, the higher the arch height, which will easily cause unnecessary waste of space. At the same time, under the action of self-weight and vertical load, the existing arch space steel truss structure uses a relatively high amount of steel, and generates a large horizontal thrust at the floor support, causing the upper steel structure, lower structure, and support The higher cost and more rods will also result in higher post-corrosion maintenance costs. [0003] At present, many cable dome struc...
