Friction type multi-angle tension-shear test device capable of adapting to multiple types of fasteners

Abstract

The invention discloses a friction type multi-angle tension-shear test device capable of adapting to multiple types of fasteners. The device is composed of two connecting plates, two clamping plates,two fastening bases, two measuring standard blocks and bolts, the two clamping plates are fixed to the outer sides of the two connecting plates through the bolts respectively, the two fastening basesare fixed to the centers of the two connecting plates through the bolts respectively, and the two measuring standard blocks are fixed to the outer sides of the two fastening bases through the bolts respectively. The friction type multi-angle tension-shear test device capable of adapting to multiple types of fasteners is simple in structure; the multi-angle high-strength bolt or annular groove rivet friction type connection tension-shear test can be met, tested high-strength bolts or annular groove rivets and other fasteners and friction type connection test piece plates can be conveniently andflexibly replaced, and a large number of full tests can be conducted on high-strength bolts or annular groove rivets and other friction type connection test pieces.

Description

technical field [0001] The invention belongs to the field of mechanical performance test equipment, and in particular relates to a friction-type multi-angle tensile-shear test device which can be adapted to multi-type fasteners. Background technique [0002] Friction-type connections such as high-strength bolts or ring groove rivets are widely used in engineering structures. They have the advantages of convenient construction and quick on-site installation, and are important factors for the widespread promotion of prefabricated structures. Friction-type connection is a commonly used connection method compared with pressure-bearing connection. It can meet the mechanical performance of the structure under a certain load by limiting the sliding deformation of the connection. In actual engineering, frictional connections often bear the joint action of tensile force and shear force, and it is necessary to test the performance of the friction surface of fasteners and connecting pl...

AI Technical Summary

Problems solved by technology

Repeated tests of various fastener types, multiple angles, and various friction surface treatment methods put forward high requirements for the convenience of use and reusability of the test device. Due to the lack of suitable fastener friction type Connecting the tensile-shear test device, in engineering practice, it is often difficult to conduct a large number of sufficient tests on fasteners
