[0002] Building materials are various materials used in construction projects. There are many types of building materials, which can be roughly divided into: inorganic materials, which include metallic materials and non-metallic materials; organic materials, which include plant materials, synthetic polymer materials and asphalt materials; composite materials, which include asphalt concrete, polymer concrete, etc., which are generally composed of inorganic non-metallic materials and organic materials.

[0003] In order to ensure the smooth progress of construction and improve the quality of construction, it is usually necessary to test the strength of building materials. Strength testing of building materials can often speed up the progress of construction and improve the quality to ensure the smooth progress of construction. It can be seen that it is necessary to conduct strength testing on testing materials.

[0004] In the process of strength testing of existing building materials, the strength of the building materials is often tested by squeezing them with different forces, and the squeezing force is usually increased gradually. The deformation of the building materials leads to an increase in the bearing pressure, which affects the subsequent testing results of the building materials. In addition, the bearing pressure of building materials under impact and squeezing is different, resulting in incomplete strength testing of building materials. For this reason, we propose a building material strength testing device. Utility Model Content
