Integral Lifting Method and System for Asymmetric Inner Ring Truss and Cable Dome

Abstract

The invention relates to a method and system for integral lifting of an asymmetric inner ring truss and a cable dome. The method includes: assembling the inner ring truss and the cable dome, connecting the cable dome and the inner ring truss; The positions to be installed of the trusses are arranged at intervals and fixed on the ground, and multiple lifting frames are connected to each other; multiple lifters are fixed on the top of the corresponding lifting frames, and multiple lifters are connected to the inner ring truss correspondingly; multiple The tractor is fixed on the top of the corresponding lifting frame, and multiple tractors are connected to the cable dome correspondingly; multiple lifters are used to lift the inner ring truss horizontally upwards, and multiple tractors are used to tension the inner ring truss during the process of lifting the inner ring truss The cable dome is radially pulled by the tractor, so that the horizontal force is applied to the inner ring truss through the cable dome to control the horizontal displacement of the inner ring truss; alternately lift the inner ring truss and tension the cable dome until the inner ring truss reaches the design elevation .

Description

Technical field [0001] The present invention relates to the field of building construction, especially in an asymmetric intraocular truss and a total improvement method of the soda top and its system. Background technique [0002] The large-scale sports venue is often used to use the Saua top structure, with the large open sunflower curved dome structure including support structures, outer ring grid, large open softe and inner ring truss, wherein the inner ring truss is 150m × 110m and Northern High South Low The height is 6.1m to 12.5m, the inner ring truss is from 700T, the inner ring truss and the total weight of the inner ring truss, and the span is large, the weight is large, and the cross-collaborative improvement is difficult to improve the traditional lift bracket. [0003] China Patent CN101446135A discloses an overall improvement system of ultra-high-altitude super long girder jacket method and its construction method, see figure 1 A schematic diagram showing the overal...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the prior art, provide an asymmetric inner ring truss and cable dome integral lifting method and its system, and solve the problem of lifting due to the asymmetrical structure of the inner ring truss and uneven gravity distribution in the prior art. During the process, there will be displacement, rotation and offset in the plane, which is easy to collide with the lifting frame, and there are potential safety hazards
