Net rack integral lifting structure

Abstract

The invention relates to a net rack integral lifting structure. The net rack integral lifting structure comprises a plurality of groups of lifting devices arranged on the periphery of a large-scale structural body, and each group of lifting devices are separately fixed to a concrete frame on the periphery of the large-scale structural body. The lifting devices comprise lifting platform beams, lifters, temporary steel columns and temporary lifting appliances, one ends of the lifting platform beams are fixed to the upper part of the inner side wall of the concrete frame, the temporary steel columns are perpendicularly fixed to the other ends of the lifting platform beams, connection rods are further arranged between the temporary steel columns and the concrete frame, the lifters are fixed to the ends, away from the concrete frame, of the lifting platform beams, and the temporary lifting appliances are connected with the lifters through steel strands. According to the net rack integral lifting structure, extension combination of lifting equipment is adopted, and lifting weight, span and area are not limited; and the lifting process is very safe, a net rack can be locked at any position in the lifting process, any lifter can be further adjusted independently, and the adjustment precision is high.

Description

technical field [0001] The invention relates to the field of construction, in particular to an overall lifting structure of a network frame. Background technique [0002] Since the 20th century, the spatial structure has been greatly developed all over the world. The space grid structure is a kind of space grid structure. The so-called "spatial structure" is relative to the "plane structure". It has the characteristics of three-dimensional function. The space structure can also be regarded as the expansion and deepening of the plane structure. [0003] Since the advent of the space structure, it has been welcomed by people for its high-efficiency mechanical performance, novel and beautiful form, and fast and convenient construction. In stadiums, convention centers, cultural facilities, transportation hubs and even industrial plants that require large spans and large spaces, space structures can be seen everywhere. [0004] With the increasing development of modern grid eng...

AI Technical Summary

Problems solved by technology

[0004] With the increasing development of modern grid engineering construction, safety and quality problems in the project are still unavoidable. The general grid construction process cannot effectively control the construction quality and safety, such as bulk in place at high altitude, assembly in place by strips and blocks, and These methods of high-altitude sliding and in-place assembly increase the high-altitude operations, and require the erection of large-scale scaffolding for construction, which reduces the safety factor and increases construction costs. High-altitude assembly is more cumbersome and reduces efficiency.
