Description

Technical Field

[0001] The utility model relates to the technical field of steel structure production, in particular to a steel structure strength detection structure. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Before construction, in order to ensure the construction quality, it is necessary to detect the steel strength to ensure the construction stability and personnel safety.

[0003] However, there are still deficiencies in the prior art. In the prior art, the steel structure is usually fixed on the detection table, and then the strength of the steel structure is detected by pressing down with a pressing plate and a pressure sensor thereon. When the steel structure bends, the two sides of the steel structure will move towards the middle, but since the two sides of the steel structure are fixed, the detected data will be affected.

[0004] Therefore, we propose a steel structure strength detection structure to solve this problem. Content of the Utility Model

The steel structure is subjected to extrusion test by the squeezer.
