Construction method for adjusting distance between column grids of steel structure

Abstract

The invention relates to a construction method for adjusting column grid spacing of a steel structure, which belongs to the technical field of structure construction and comprises the following operation steps of: 1, pre-embedding anchor bolts before pouring a concrete bottom plate; and secondly, the pouring process of the concrete bottom plate is conducted. And thirdly, the steel rib supporting assembly is hoisted and corrected. And fourthly, after the steel rib supporting assembly is hoisted, the steel rib beam is hoisted, the two sides of the steel rib beam and the steel rib supporting assembly are connected and fixed through high-strength bolts through connecting plates, and welding and fixing between the steel rib beam and the steel rib supporting assembly are completed. And fifthly, the upper layer of the steel reinforced beam is measured, the supporting position of the box type column is determined, a mark is made on the steel reinforced beam, hoisting of the box type column is completed, correction needs to be conducted when the box type column is hoisted, and welding and fixing are completed. The structure has the advantages of being simple and convenient to construct, good in safety and stability, free of influence of column grid spacing and high in structure space utilization rate. The problem that the upper-layer column moves to any position is solved.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a construction method for adjusting the distance between column nets in a steel structure. Background technique [0002] With the rapid development of the domestic economy and the improvement of people's living standards, the functional requirements of buildings have been upgraded from simple and basic functional requirements to large-span and large spaces. In the face of a prefabricated steel structure building with a large span and a large space, the original column grid spacing will affect the aesthetics of the building and the use of functions. Therefore, in this case, seeking a safe, economical, simple and convenient solution is one of the important researches on the current prefabricated steel structure.
