Temporary reinforcing method of circular pipe components

Abstract

The invention belongs to the field of building structural construction, in particular to a temporary reinforcing method of circular pipe components. The temporary reinforcing method has the following specific construction steps that (1) according to the specifications of reinforced circular pipes, appropriate steel angles and steel angle fasteners matched with the steel angles are selected; (2) according to the lengths of the reinforced circular pipes, the lengths of the steel angles and the number of the steel angle fasteners are determined; (3) before the circular pipe components are stressed, two steel angles are symmetrically arranged on the two sides of each reinforced circular pipe and fixed through the corresponding steel angle fasteners; and (4) after structural construction unloading, the steel angle fasteners are loosened, steel angle reinforcing devices are dismantled, and reinforcing of the circular pipe components is completed. The temporary reinforcing method facilitates construction, and construction does not need machines such as a crane and can be achieved through manual work.

Description

technical field [0001] The invention belongs to the field of building structure construction, and in particular relates to a temporary reinforcement method for circular pipes. Background technique [0002] At present, many space structures are steel grid structures, and most of their structural members are circular pipe members; during the construction and installation of steel grid structures, it is inevitable to encounter the problem of insufficient bearing capacity of some members. For example, during the hoisting process of the network frame in blocks, the network frame webs on the upper part of the temporary support frame; during the network frame jacking construction, the network frame webs connected to the jacking point; Frame web bars; during the sliding construction of the grid frame, the sliding support points of the non-original structural support positions on the sliding track are the upper frame web bars, etc., due to the increase in the load at the fulcrum posi...

Problems solved by technology

[0003] Under normal circumstances, due to the characteristics of the nodes of the grid structure, it is not convenient to add temporary members for strengthening treatment, and the members with insufficient bearing capacity are replaced with members with larger cross-sections; after the members are replaced, due to the increase in the stiffness of the replaced members, Under the design load, it will lead to the redistribution of the internal force of the structure near the replacement rod, and the structure needs to be re-checked and calculated, which will increase the workload and increase the steel consumption of the structure.
