Abstract
Description
technical field
[0001] The invention relates to the technical field of construction equipment, in particular to a concrete resilience tester for construction engineering. Background technique
[0002] The hammer is a kind of testing instrument commonly used in construction engineering. It uses a spring to drive a heavy hammer, so that the heavy hammer impacts the bullet dry that is in vertical contact with the concrete surface with a certain kinetic energy to achieve rebound and indicate the rebound distance. According to The calculation can get data such as the strength of the concrete. It is convenient and easy to use to detect the concrete. It can quickly detect the construction of a part of the concrete. However, in actual use, there are still some problems that need to be solved:
[0003] 1. After using the spring hammer to detect the rebound once, it needs to be hung on the hook at the tail. However, due to the change of the vertical direction of the concrete surface t...
