Abstract

The invention relates to a method for detecting the firmness of a steel structure truss after butt joint. Equipment for detecting the firmness of the steel structure truss after butt joint is used inthe method. According to the method, the problem that the overall quality of the steel structure truss is affected due to the fact that a traditional truss inspection method adopts manual observation,and the manual observation has a certain uncertainty, is inaccurate and easily makes wrong misjudgment can be solved; after the truss is formed into an I shape, when bending is caused due to externalcauses, the overall structure of the I-shaped steel structure truss is inclined and deformed if the bent truss is not processed, so that the installed I-shaped steel structure truss is not stable; and when the I-shaped steel structure truss is inspected, multiple points of the I-shaped steel structure truss can be detected to obtain reliable data so as to provide accurate analysis, and bending ofthe I-shaped steel structure truss can be effectively processed.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a method for detecting the firmness of steel structure trusses after butt joint. Background technique [0002] Trusses are widely used in steel structures, such as roofs (roof trusses, etc.) In offshore oil production platforms, steel trusses are commonly used as the main components of the load-bearing structure. Various types of steel grids, which are widely used in the roof structure of large-span public buildings, belong to space steel trusses. Various types of towers, such as TV, power transmission, drilling, crane towers and mast towers, commonly use space steel trusses composed of three-sided, four-sided or multi-sided planar trusses. Steel trusses are welded to each other or formed into the required shape for common use. For a truss that forms an "I"-shaped structure, it is necessary to test the stability and firmness of its structure and use it after meeting th...
