Description

Gypsum board shock resistance tester Technical Field The application relates to the technical field of building material test devices, in particular to a gypsum board impact resistance tester. Background The free falling type impact tester simulates the impact condition in actual use by allowing a weight to freely fall onto the surface of a sample from a certain height, and has the advantages of simple operation and low cost. The existing free falling impact tester has the problem of inaccurate positioning, and particularly when a rectangular test piece is processed, the steel ball is difficult to ensure that the steel ball can accurately hit the centroid position of the surface of the test piece, so that the instability and unrepeatability of a test result are caused, and the reliability and the accuracy of the test are seriously affected. To this end, the application provides a gypsum board impact tester. Disclosure of utility model Aiming at the defects of the prior art, the application provides a gypsum board impact resistance tester, which overcomes the defects of the prior art and aims to solve the problem that the existing free falling impact resistance tester has inaccurate positioning, and particularly, when a rectangular test piece is processed, the steel ball is difficult to ensure to accurately hit the centroid position of the surface of the test piece, so that the instability and unrepeatability of test results are caused, and the reliability and accuracy of the test are seriously affected.
