Abstract

The invention relates to the technical field of construction equipment, and discloses a concrete resiliometer for constructional engineering. The concrete resiliometer comprises a shell, a tail coveris fixedly mounted on the back surface of the shell, an elastic striking rod is movably mounted on the front surface of the shell, a central guide rod is fixedly connected to the end, located in the shell, of the elastic striking rod, and an elastic striking hammer movably sleeves the outer ring of the central guide rod. An elastic striking tension spring is fixedly connected between the front face of the elastic striking hammer and the interior of the shell, a guide block is fixedly connected to the end, close to the tail cover, of the central guide rod, the outer ring of the guide block is movably sleeved with a pressure spring, a center hole is formed in the middle of the guide block, and a battery is fixedly installed at the inner top of the center hole. An annular hole groove is formed in the middle ring position of the guide block, and a wire is spirally wound in the annular hole groove. By means of the electromagnetic design and the design of the two matched sliding sleeves, itcan be guaranteed that stability is good, and detection precision is high.

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...
