Static force load testing device for concrete beam

Abstract

The invention discloses a static force load testing device for a concrete beam. The device comprises a base (1), a crossbeam (2), and an upright post (3) provided with an external thread, wherein the upright post (3) is respectively fixedly connected with the base (1) and the crossbeam (2) in a manner of screw-thread fit; a hydraulic jack (6), a load transducer (8) and a load allocation beam (7) are sequentially mounted on the bottom surface of the crossbeam (2); first spherical hinges (10) used for transmitting load to the concrete beam (19) are respectively arranged at the two ends of the bottom surface of the load allocation beam (7); an adjusting hole (5) is formed in the top of the base (1); the base (1) is fixedly connected with a support seat (9) used for supporting the concrete beam (19) through the adjusting hole (5); a second spherical hinge (11) is arranged at the top of the support seat (9); a linear displacement sensor used for detecting the deformation of the concrete beam (19) is mounted on the base (1); the hydraulic jack (6) is used for applying the load to the concrete beam (19), and a computer (16) is used for analyzing and processing acquired signals so as to monitor the test process; the crossbeam (2) and the support seat (9) are regulated to adapt to load tests of concrete beams of different sizes; the overall device can be dismounted and mounted, and is convenient to store and transport.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a static loading test device for concrete beams. Background technique [0002] As we all know, in the field of civil engineering, concrete beams are the main load-bearing members of the structure, and the research on the bearing capacity of concrete members has become the focus of structural engineering research, and the static loading test of concrete beams is one of the more effective techniques One of the means. At present, in the test of the static performance of concrete beams, most of them are temporary loading devices assembled by stacking heavy objects, etc., and the test errors generated during the test process are relatively large; and the existing loading devices are generally fixed integral parts that occupy a large area. The structure is inconvenient to move, and it can only be applied to the loading test of a single-size concrete beam, so the utilization rate is lo...
