The strength of building materials refers to the mechanical properties of the material, the ability of the material to resist damage, and the instinctive properties between the molecules or particles that make up the material. It is related to its molecular crystal structure and density. Strength is a relative concept for building materials. For example, the strength of concrete is stronger than that of bricks. Here it refers to hardness, which is called compressive strength in the specification and is called bearing capacity per unit area when put into calculation. In order to check whether the building materials are qualified, it is usually necessary to test their hardness, bending resistance and tensile strength.

The detection hydraulic cylinder 2 is extended and contacts the detection member 856 for detection, and the pressure data during the detection is transmitted to the system for recording through the pressure sensor.

[0060] In the second detection state, the output end of the horizontal hydraulic cylinder 63 can drive the moving end of the guide rail 62 and one of the mounting seats 61 to move, and the mounting seat 61 moves to pull one end of the detection member 856, so that the detection member 856 can be tested for tensile strength data under an adjustable temperature and humidity environment, and the strength data of the detection member 856 can be fully tested;

[0061] In the third detection state, the output end of the electric push rod 6502 drives the positioning pin 6501 to move to the outside of the second positioning groove 650 and the first positioning groove 648, thereby canceling the limit on the slide 642 and the adjusting member 644, so that the slide 642 can move along the guide groove 641 as the path, and the adjusting member 644 can rotate around the rotating shaft 645 as the center of the circle, and then the support member 51 is detected to be separated from the detection member 856. By detecting the contact between the output end of the hydraulic cylinder 2 and the surface of the detection member 856, the anti-bending data of the detection member 856 can be detected, and when the two ends of the detection member 856 are fixed and limited, the two ends of the detection member 856 can move along the guide groove 641 as the path, and can rotate around the rotating shaft 645 as the center of the circle, which can simulate the anti-bending detection data of the two ends of the detection member 856 in the free state, and avoid the phenomenon of separation in the test of the detection member 856, which can improve the accuracy of the detection data and reduce the risk factor in the detection.
