High-position equal-elevation with-column slipping structure and method for large-span space structure

Abstract

The invention belongs to the field of steel structure buildings, and particularly relates to a high-position equal-elevation with-column slipping structure and method for a large-span space structure. The slipping structure comprises supporting steel columns and inter-column beams perpendicularly and fixedly connected with the supporting steel columns. Slipping rails are laid on the inter-column beams and slidably provided with slipped steel columns. Slipping shoes are fixedly arranged on the two sides of the slipped steel columns. The slipping shoes on one sides of the slipped steel columns are connected with hydraulic jacking and pushing devices arranged on the slipping rails. By adoption of the high-position equal-elevation with-column slipping structure and method, the problems that the large-span space structure is high in roof gravity center and poor in stability under the condition that solid web columns have no lateral support, and column base slipping is difficult to implement are solved.

Description

technical field [0001] The invention belongs to the field of steel structure buildings, and specifically relates to a large-span space structure, high-level and equal-elevation column sliding structure and method. Background technique [0002] After the vigorous promotion of my country's construction system and the vigorous development of the industry for many years, the steel structure has become an indispensable part of the construction system. Combining its advantages of high strength, light weight, good overall rigidity and strong deformation ability, steel structures are mostly used In long-span, super high-rise and super-heavy buildings. [0003] With the application of new technologies and techniques, cumulative slip construction technology has gradually been widely used in the construction of large-span spatial structures by the industry. At present, this technology is mainly used in structures with flat roof structures and consistent column bottom or column top eleva...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-span spatial structure with column sliding structure and method at high level and equal elevation, so as to solve the problem of poor stability in the case of high center of gravity of the roof of the large-span spatial structure and no lateral support of the solid abdominal column, and it is difficult to implement the column Difficulty of slipping at the bottom, and difficult to implement slipping at the top of the column when the roof support of the column top is irregularly undulating or the height of the support is small
