Concrete compressive strength detection device

Abstract

The invention provides a concrete compressive strength detection device. The device comprises a bottom plate, supporting rods, a top plate, a centering mechanism and a loading mechanism. The centeringmechanism comprises an infrared transmitting tube, an infrared receiving tube, a sliding plate and an electric push rod; the loading mechanism comprises a pressing block, a pressure sensor, a hydraulic cylinder, a controller and a display screen; when a concrete test piece is placed at a pressed station on the bottom plate, if the concrete test piece shields the infrared transmitting tube in thebottom plate, the controller controls the electric push rod on the same side of the shielded infrared transmitting tube to push the concrete test piece to drive the concrete test piece to move to thepressed station, then the controller controls the hydraulic cylinder to drive the pressure block to move downwards to break the concrete test piece, compressive strength information in the detection process is displayed on the display screen, it can be guaranteed that the centers of the concrete test piece and the pressing block are consistent, detection errors caused by position deviation of theconcrete test piece are prevented, and the detection effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of concrete detection, in particular to a concrete compressive strength detection device. Background technique [0002] The compressive strength of concrete is an important index to measure the quality of concrete. The current test of concrete compressive strength basically applies a certain external force to the concrete specimen and continues to load until it breaks. By recording the compression process of the concrete specimen The load value obtained in this way is used as an index to evaluate the compressive strength of concrete. [0003] Before testing, the current detection device will cure the concrete to obtain a concrete specimen with a cubic structure, and then move the concrete specimen to the detection device for detection. The current detection method is basically to place the concrete specimen manually. If the test is carried out on the workbench, there will be a problem of inaccurate alignmen...

Problems solved by technology

[0003] Before testing, the current detection device will cure the concrete to obtain a concrete specimen with a cubic structure, and then move the concrete specimen to the detection device for detection. The current detection method is basically to place the concrete specimen manually. If the test is carried out on the workbench, there will be a problem of inaccurate alignment of the concrete specimen when placed manually, so that the uneven force of the concrete specimen will appear during the test, which will eventually affect the analysis of the compressive strength of the concrete specimen
