Building material strength detection device and detection method

Abstract

The invention relates to a building material strength detection device, which comprises a support table for placing a test block, a test frame arranged on the support table, a test assembly connectedto the test frame and a test block clamping device arranged on the support table. A test area is arranged in the middle of the support table, and the test frame is arranged behind the test area. The test assembly comprises a hydraulic cylinder connected to the test frame, a test head connected to the front end of the hydraulic cylinder and a pressure display instrument arranged on the test frame.The clamping device comprises a fixed clamping assembly and a movable clamping assembly which are arranged on the two sides of the test area respectively, a first arc-shaped clamping plate is arrangedon the fixed clamping assembly, a second arc-shaped clamping plate is arranged on the movable clamping assembly, openings of the first arc-shaped clamping plate and the second arc-shaped clamping plate are opposite, and anti-skid grooves are formed in the opposite arc surfaces. According to the device, concrete test blocks can be fixed more firmly, the fixing requirements of the test blocks withdifferent sizes can be met, and a good test effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building material detection, in particular to a building material strength detection device and detection method. Background technique [0002] Building materials can be divided into structural materials, decorative materials and some special materials, among which structural building materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, composite materials, etc. No matter what kind of structural building materials need to complete a series of quality inspections before they are put into use, including strength testing of building materials, and strength testing requires the use of specific strength testing equipment, and for different Different testing equipment and testing methods are selected for the specifications, shapes and shapes of materials. [0003] At present, in the quality inspection of building materials, for the inspection of concret...

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: through the left and right adjustment devices, turning the knob, due to the meshing connection between the driving gear and the rack plate, and the sliding connection between the slide bar and the chute in the chute plate, the rack plate and the rack plate are realized. The left and right adjustment of the inner fixing plate realizes the left and right fixing of the material on the workbench. However, when the inner fixing plate clamps the test material, there is no structure in this technical solution to limit the reverse rotation of the stop gear and the rack plate, so that the inner The fixed plate cannot clamp and fix the test material, and the test material will loosen and shift during the test, which will affect the test results
