A construction method for synchronous lateral movement of high and low span grid structures

Abstract

This application relates to a construction method for synchronous lateral movement of a high and low span grid structure, which specifically includes the following steps: building an assembly platform, assembling the first grid segment on the assembly platform, laying slide rails on the concrete columns on both sides, two Set up a temporary support between the slide rails, lay the third slide rail on the temporary support, lower the first network frame to the slide rail in sections, connect the track clamping equipment with the slide rail, and then connect the track clamping equipment The power rod of the hinged hydraulic cylinder is hinged with the structural support fixedly connected to the first grid segment, so that the first grid segment moves forward, and the second grid segment is assembled on the assembly platform, and then the second grid segment is assembled. The second network frame segment is lowered until the slide rails are spliced ​​with the first network frame segment, and then the power rod of the hydraulic cylinder is hinged with the structural support of the second network frame segment, and the first network frame segment and the second network frame segment The frame segments are moved forward together and repeated continuously until the overall grid frame splicing is completed, and then moved to the predetermined position, which has the effect of reducing the overall engineering amount.

Description

Technical field [0001] The present application relates to the technical field of grid structure installation and construction, in particular to a construction method involving a high and low spanning grid structure synchronous traverse. Background [0002] The top of some existing buildings is often a grid frame structure, the current construction method of more grid structure is high-altitude parallel slip method, in the upper part of the building to set up a assembly platform for the grid frame assembly, when the first assembly unit is assembled, that is, it falls to the slip track, with traction equipment to slide forward a certain distance, and then assemble the second assembly unit on the assembly platform, and slide, so that the section by section assembly continues to ask before sliding, until the entire grid is assembled and slid to the position in place. [0003] The existing grid frame displacement is generally by setting the displacement reaction frame, and then articu...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the applicant believes that multiple displacement reaction frames need to be installed during the entire grid displacement process, and they need to be continuously installed and disassembled, which has the disadvantage of a large overall engineering workload
