[0003] During the construction process, considering the safety after the completion of the house construction, it is necessary to conduct strength testing on the built house walls during the construction process. Usually, people will use concrete rebound tester to test the compressive strength of concrete. The basic principle of the rebound tester is to keep it vertical or horizontal with the tested wall, use a spring to drive the heavy hammer, and the heavy hammer hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, so that the local concrete deforms and absorbs part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is fully converted into potential energy, the heavy hammer rebounds to the maximum distance, and the instrument displays the maximum rebound distance of the heavy hammer in the name of rebound value;

[0004] When testing the wall strength using an existing concrete rebound tester, the wall is usually tested manually by holding the concrete rebound tester directly without basic positioning assistance for the concrete rebound tester, which will cause a large error between the detected data and the actual data. Therefore, a building strength measurement device for construction is proposed to solve the above problem. Utility Model Content
