Abstract

The invention relates to a steel box girder bending performance detection device for road and bridge construction. The detection device comprises connecting seats, a rack, a starting switch, a reset switch, a telescopic assembly and a pressure test assembly, the connecting seats are fixedly connected to the two outer sides of the rack, the telescopic assembly is mounted at one inner side in the rack, and the pressure test assembly is mounted between the outer side of the rack and the telescopic assembly. The steel box girder is placed in the rack, the starting switch is pressed, and the starting switch sends out a signal; the control module controls the pressure test assembly to operate for two seconds after receiving the signal and then controls the telescopic assembly to operate, the telescopic assembly operates to drive the pressure test assembly to move downwards to make contact with the steel box girder, and the pressure test assembly is used for carrying out bending detection on the steel box girder, so that the bending of the steel box girder can be detected, and the unqualified steel box girders are avoided.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the bending performance of a steel box girder used in road and bridge construction. Background technique [0002] In the construction of roads and bridges, steel box girders need to be used, but in order to ensure the construction quality, the bending performance of steel box girders needs to be tested in advance, and unqualified steel box girders cannot be used. At present, steel box girders are often used in engineering. It is widely used in road and bridge construction, but the structure of steel box girder is complex, and the quality of steel box girder needs to be guaranteed to avoid unqualified phenomena that lead to rework problems, which increases construction costs and time costs. [0003] Therefore, it is necessary to design and develop a steel box girder bending performance testing device for road and bridge construction that can perform bending testing on s...
