Embodiment Construction

[0031] The present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific implementation manners described here are only used to explain relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only parts related to the present disclosure are shown in the drawings.

[0032] It should be noted that, in the case of no conflict, the implementation modes and the features in the implementation modes in the present disclosure can be combined with each other. The present disclosure will be described in detail below with reference to the drawings and embodiments.

[0033] The shock-absorbing tenon has the characteristics of low yield strength and good ductility. As a simple structure, excellent performance, and economical energy-dissipating shock-absorbing device, compared with viscous dampers, it has the advantages of no leakage, good dura...

Abstract

The invention provides a damping tenon test bed and a test method, relates to the technical field of bridge construction, and aims to solve the problems of low efficiency and complex operation of a damping tenon test device. The damping tenon test bed comprises an upper clamping assembly and an L-shaped clamping jaw movably connected to a test bed rack, the upper clamping assembly is connected with an actuator of the test bed, and the upper clamping assembly is used for clamping a ball head of the damping tenon; the upper clamping assembly comprises a movable clamping head and a fixed clamping head matched with the movable clamping head, the movable clamping head is movably connected to the fixed clamping head, the fixed clamping head is connected to the actuator, and the movable clamping head and the fixed clamping head are each provided with a trapezoidal groove for containing the ball head; the clamping jaws are used for clamping the side face and the upper surface of the flange plate of the damping tenon. The damping tenon test bed provided by the invention is used for testing the reciprocating performance of the damping tenon.

Description

technical field [0001] The disclosure relates to the field of bridge construction, in particular to a shock-absorbing tenon test bench and a test method. Background technique [0002] Shock-absorbing mortise is a cantilever beam-type steel rod damper. When it is used on a bridge and encounters an earthquake, it uses the cumulative plastic deformation of the metal after yielding to achieve the purpose of dissipating earthquake energy. [0003] At present, there are many specifications and models of damping tenons in use. When testing the performance of the shock-absorbing tenon, the shock-absorbing tenon needs to be fixed on the test stand, but the fixed position of the test stand is determined, which cannot meet the fixing needs of the shock-absorbing tenon of various sizes and specifications. In the prior art, the common method of fixing the shock-absorbing mortise needs to use an adapter plate, which is indirectly fixed on the test bench through the adapter plate. Howeve...
