Abstract

The invention discloses a fastening device for high-strength bolt connection friction surface anti-sliding coefficient detection. An operation platform and a fastening component form an integral structure part; the operation platform comprises the assemblies of a ground fixing device, transverse supporting pieces, vertical supporting pieces and a table top platform piece, wherein the transverse supporting pieces, the vertical supporting pieces and the table top platform piece are mutually fixedly connected to form a frame form support body structure, and the legs of the vertical supporting pieces are fixed on the ground by ground fixing pieces; the fastening component comprises the assemblies of a load part formed by a rib, a second rib, a movable rib, an anti-sliding coefficient tensile test piece, a high-strength bolt, a screw jack and a spring, and a transverse rib, wherein the assemblies are mutually fixedly connected, and the fastening component is fixed on the table top platform piece by a fixing block. The fastening device is simple in structure, convenient to operate, time-saving, labor-saving, improved in work efficiency and high in safety.

Description

technical field [0001] The invention relates to a test and detection device, in particular to a fastening device for the anti-slip coefficient of a high-strength bolt connection friction surface, and belongs to the technical field of fastener connection detection devices in steel structure fabrication and installation. Background technique [0002] According to the "Steel Structure Engineering Construction Quality Acceptance Code" (GB50205), the anti-slip coefficient test is carried out on the friction surface of the high-strength bolt connection, and the design of the anti-slip coefficient in the test should meet the requirements of the specification. According to Article 6.3.1 of the "Code for Construction Quality Acceptance of Steel Structure Engineering", the steel structure fabrication and installation unit shall conduct the anti-slip coefficient test and re-inspection of the friction surface of the high-strength bolt connection according to the provisions of Appendix B ...
