Abstract

The present invention relates to a combined one-way hinge for the loading test of right-angled specimens, which relates to the technical field of mechanical performance testing of reinforced concrete structures, and includes a right-angle wing assembly, a roller shaft and a support seat assembly; the right-angle wing assembly includes a right-angle plate, a first concave The groove member and a plurality of first reinforcing ribs arranged between the right-angle plate and the first groove member, the opening of the right-angle plate is opposite to the opening of the first groove member and the right-angle plate is centered with the first groove member Arrangement; the supporting seat assembly includes a base plate, a podium, a second groove member, and a plurality of second reinforcing ribs arranged between the abutment and the second groove member; the opening of the first groove member and the second groove The openings of the components are oppositely arranged, and the roller shaft is arranged between the first groove component and the second groove component and abuts against the groove bottom of the first groove component and the groove bottom of the second groove component. The one-way hinge loading of the invention eliminates the eccentric bending moment of the test piece constrained by the fixed support, and greatly improves the test accuracy.

Description

technical field

[0001] The invention relates to the technical field of mechanical performance testing of reinforced concrete structures, and more particularly, relates to a combined one-way hinge for loading tests of right-angle specimens. Background technique

[0002] Reinforced concrete structures are widely used in above-ground and underground projects. In addition to the above-ground structures that are common in daily life, there are also urban lifeline projects such as underground box culverts, pipe galleries, and tunnels. Conventional reinforced concrete members are regular cuboid structures, such as beams, slabs and columns, etc., but in complex engineering environments and stress requirements, there are also a lot of special-shaped reinforced concrete members, such as T-shaped, L-shaped, square right-angled members, round Shaped semicircular components are commonly used component forms in engineering construction. Engineering construction consumes a lot of manpower...
