Description

TECHNICAL FIELD

[0001] The utility model relates to concrete member strength detection technical field especially relates to a concrete member strength detection device. BACKGROUND

[0002] Concrete member strength refers to the compressive strength of concrete under specific conditions, which is an important indicator for evaluating the quality of concrete, and the rebound method is a common method for detecting the strength of concrete members. The rebound method uses a rebound hammer to measure the rebound value of the concrete surface, combines the carbonation depth of the concrete, and calculates the compressive strength of the concrete. This method is simple to operate and suitable for rapid detection of concrete strength. The concrete rebound hammer is the main rebound method detection instrument. The concrete rebound hammer uses a spring to drive a hammer and through a striking rod to hit the surface of the concrete, causing instantaneous elastic deformation of the recovery force. The hammer drives the pointer to bounce back and indicate the distance of the bounce back. The rebound value (the ratio of the bounce back distance to the distance between the hammer and the striking rod before impact, calculated as a percentage) is used as one of the indicators related to the compressive strength of concrete to determine the compressive strength of concrete.

[0003] When detecting the strength of concrete members by the rebound method, the surface of the concrete member is generally divided into measuring zones, and the average rebound value of the measuring zone is calculated. Each measuring zone has 16 areas of the same size. Currently, when dividing the measuring zone, the tester usually draws the measuring zone on the surface of the concrete member with a pen or covers the surface of the member with a paper with the measuring zone drawn in advance. Both of these methods for dividing the measuring zone are cumbersome and time-consuming, especially when measuring multiple members or multiple measuring zones on a member.
