Extensible high-altitude conjoined steel structure

Abstract

The invention relates to construction facilities in building industry, in particular to an extensible high-altitude conjoined steel structure of a high-altitude large-span corridor steel structure frame and a reverse construction method of the extensible high-altitude conjoined steel structure set up on the high-altitude large-span corridor structure frame. The steel corridor structure is stable in structure and meets requirements of expansion and contraction after being heated and cooled, and safe and long-time use is realized really. Consequently, the extensible high-altitude conjoined steel structure has the advantages that the structure is simple and convenient in process, convenient in operation and free of space occupation, and quality of the structure is qualified in an acceptance check, so that repeated construction is avoided; mechanical cost is saved when compared with adoption of a large-tonnage crane, so that the structure has high economic benefit; the structure is low in noise, free of water pollution and waste gas pollution, few in lost and scattered solid waste and the like.

Description

technical field [0001] The invention relates to a construction facility in the construction industry, in particular to a high-altitude and large-span corridor steel structure frame. [0002] The invention also relates to a building construction method, in particular to a reverse construction method erected on a high-altitude long-span corridor structure frame. Background technique [0003] In recent years, with the development of engineering technology, the forms of high-rise buildings have become increasingly diversified. The conjoined steel structure is loved by architects because of its grandeur and modern atmosphere. How to complete the construction of high-altitude conjoined steel structures with high quality and high efficiency is an important issue. [0004] Between the east and west towers of the Rugao Comprehensive Administrative Service Center Project, there is a high-altitude corridor with a pull-up and bottom-supporting steel structure. The 13th and 16th floors...

AI Technical Summary

Problems solved by technology

The practical results show that the oblique hanging technology of the reverse member in different areas is applied to the hoisting of the upper and lower support-type conjoined steel structures of high-rise buildings, which is safe, reliable, and economical and reasonable. Therefore, there are many problems in the erection of the steel structure. For example, the problem of thermal expansion and contraction needs to be solved.
