Large-span net rack aloft pairing, installing and overall horizontal moving method

Abstract

The invention discloses a large-span net rack aloft pairing, installing and overall horizontal moving method. The method includes the following steps of erecting a scaffold operation platform at the right end of a frame in the length direction of the factory frame; arranging two parallel slide rails on the platform, wherein the rails extend in the length direction of the frame; splicing and welding a first net rack on the platform; making the first net rack slide along the rails aloft, placing the first net rack on the rails temporarily after the first net rack leaves the platform so that a next net rack can be spliced, making the two net racks slide aloft together after the two net racks are spliced, and sequentially conducting operation for subsequent net racks; splicing all the net racks and making the net racks slide together; fixing all the net racks sliding in place to the factory frame; detaching the scaffold operation platform. The method is easy to operate, small in labor input, high in work efficiency, safe and reliable; especially under the condition that field conditions are limited, the construction progress can be greatly improved, and the construction cost can be better saved.

Description

technical field [0001] The invention relates to the technical field of on-site preparation, handling or processing of building materials or building components, in particular to the technical field of transportation or assembly of building components. Background technique [0002] The traditional installation methods of steel roof trusses and network trusses are ground assembly, welding, assembling, and then hoisting in pieces or as a whole. At present, in the construction process of large-scale steel structure buildings, factors such as site constraints, too large span of the factory building structure, and too high installation height have certain influence on the ground assembly of steel grids and roof trusses, especially when the grid span is large, it is even more inconvenient It is very difficult to install it with traditional construction methods because of the high-altitude hoisting in groups. If the conventional high-altitude bulk solution is adopted, a large numbe...

AI Technical Summary

Problems solved by technology

If the method of overall assembly and overall hoisting on the ground is adopted, the grid frame must be installed first before other work in the area covered by the grid frame can be carried out, which will have a great impact on the construction of the internal equipment foundation and the installation period of the equipment in the workshop
