Building foundation pit steel support structure performance detection equipment

Abstract

The invention relates to the technical field of steel supporting structures, and discloses building foundation pit steel supporting structure performance detection equipment which comprises a shell, apositive plate is fixedly connected to the inner wall of the shell, a negative plate is fixedly connected to the inner wall of the shell, and a first spring is fixedly connected to the inner wall ofthe shell. A piezoresistor is fixedly connected to the position, close to the top of the first spring, of the inner wall of the shell, a sliding plate is fixedly connected to the bottom of the first spring, balls are movably connected to the outer side of the sliding plate, a dielectric plate is fixedly connected to the bottom of the sliding plate, and a connecting rod is fixedly connected to thebottom of the dielectric plate. According to the building foundation pit steel support structure performance detection equipment, through movement of the dielectric plate, the equipment can be conveniently applied to a steel plate detection production line, the detection efficiency is improved and the yield is increased. The small bending of the surface of a steel plate is prevented from being ignored due to improper manual operation in the detection process, so that the unqualification rate of the steel plate is reduced, and the engineering quality is improved; thus improving engineering security coefficient.

Description

technical field [0001] The invention relates to the technical field of steel support structures, in particular to a performance testing device for steel support structures of building foundation pits. Background technique [0002] The steel support structure of the building foundation pit is to enhance the stability of the engineering structure. It has high requirements for the rigidity of the steel material. If the rigidity of the steel material does not meet the standard, it will have a fatal impact on the engineering structure. When the steel plate needs to be inspected, the bending force is first applied to the steel plate for pretreatment, and then the steel plate is passed through the testing equipment to determine whether deformation occurs. [0003] The existing inspection equipment needs to carry out fixed inspection on each steel plate, which is used on the production line, and the efficiency of the inspection is low, resulting in a decrease in output. At the same ...

Problems solved by technology

[0003] The existing inspection equipment needs to carry out fixed inspection on each steel plate, which is used on the production line, and the efficiency of the inspection is low, resulting in a decrease in output. At the same time, due to improper human operation during the inspection process, the slight bending on the surface of the steel sheet will be ignored. , resulting in an increase in the defective rate of the steel plate leaving the factory, resulting in a decrease in the quality of the project and a decrease in the safety factor of the project
