Beam test support seat

Abstract

The invention relates to a beam test support seat which comprises a base plate, wherein a lower roller support seat is fixedly arranged on the upper surface of the base plate; a lower roller is put on the roller support seat; lower support springs are symmetrically arranged at two sides of the lower roller; a lower support plate is arranged on the upper surface of each lower support spring; U-shaped support plates are welded on the base plate at two sides of the lower roller support seat; each U-shaped support plate is provided with one horizontal adjusting screw; upright posts are welded at the upper ends of the two U-shaped support plates; a locking nut is arranged on the upper end part of each upright post; one cover plate is fixedly arranged at the upper end of each upright post; an adjustable test beam placement space is enclosed by the cover plates and the U-shaped support plates; an upper roller support seat is welded on the lower end surface of each cover plate; two upper pressure springs are arranged on the lower surface of the upper roller support seat; and the lower ends of the upper pressure springs are connected with upper support plates. A good constraint can be provided for the beam end in the test process, and meanwhile, displacement of the beam support seat in the horizontal or vertical direction can be limited, so that great influence of overlarge displacement on the test result is avoided.

Description

technical field [0001] The invention belongs to the technical field of beam tests, and in particular relates to a comprehensive beam test support capable of improving the lateral stability of beam components in monotone static tests and low-cycle reciprocating load tests. Background technique [0002] At present, in most structural laboratories in my country, the supports used for monotonic static tests and low-cycle reciprocating load tests of beam members are relatively simple and do not have the function of lateral limit, especially in the process of low-cycle reciprocating loads. Larger lateral displacement thus affects the test results. [0003] Aiming at the problems existing in the beam-type component test support at present, the present invention proposes a new type of test beam-end support, which can reduce or avoid beam-type component failure caused by small load or other factors during the loading process. Lateral displacement minimizes the adverse effects of late...

[0003] Aiming at the problems existing in the beam-type component test support at present, the present invention proposes a new type of test beam-end support, which can reduce or avoid beam-type component failure caused by small load or other factors during the loading process. Lateral displacement, minimizing the adverse effects of lateral displacement on test results, and can adjust the test space according to the specific cross-sectional size of the beam, so as to meet the test requirements of most beam components
