Description

Technical Field

[0001] The utility model relates to the technical field of stud bending detection, in particular to an auxiliary tooling for stud bending detection after welding. Background Art

[0002] Studs are connectors between floor beams and reinforced concrete slabs, and have the function of combined connection. At present, most load-bearing structures of high-rise buildings use rigid columns, that is, concrete is wrapped around the outer layer of steel sections, which can greatly strengthen the connection strength between steel columns and concrete and improve the overall force-bearing performance of rigid columns.

[0003] After the studs are welded, the strength of the studs needs to be tested. The test standard is that when the studs are bent to 30°, there shall be no cracks visible to the naked eye in the weld and heat-affected zone. The number of inspections shall not be less than 1% of the total number of studs and shall not be less than 10 inspection methods. When testing the strength of the studs, the operator usually holds the studs vertically to bend them, or puts a sleeve on the studs and swings the sleeve to bend the studs. When using the above two methods, the hammering method is likely to cause certain damage to the studs, and the swinging sleeve method is difficult to control the bending angle of the studs. In addition, both methods are time-consuming and labor-intensive, which reduces the inspection efficiency of the studs. Utility Model Content
