Description

Technical Field

[0001] The utility model belongs to the technical field of mortar rebound testers, in particular to a mortar rebound tester for house detection. Background Art

[0002] The mortar rebound test hammer uses a spring-driven hammer to strike the brick sample surface through a rod. The instantaneous elastic deformation generated by the restoring force causes the hammer to rebound, indicating the rebound distance. The rebound value is used as a relevant indicator for assessing the compressive strength of mortar. It is used to test the compressive strength of concrete and is the most widely used non-destructive testing instrument for concrete compressive strength in on-site testing. It is the fastest, simplest, and most economical way to determine the quality and strength of concrete.

[0003] For example, a construction fence with publication number CN210923367U is provided with a support rebound device on the main body, the support rebound device includes a support frame and a connecting piece, the two ends of the connecting piece are respectively connected to the main body and the support frame, the support frame includes a support plate and a frame leg, the frame leg is provided with a rebound groove at one end away from the support plate, a rebound rod is inserted into the rebound groove, a rebound piece is provided between the end wall of the rebound rod and the bottom wall of the rebound groove, the connecting piece includes a connecting sleeve and a connecting rod, a positioning bolt is threadedly connected to the outer edge side wall of the connecting sleeve, and a connecting groove is provided on the outer side wall of the main body, thereby achieving the effect of reducing the error in the measurement data caused by the operator supporting the mortar rebound tester for a long time;

At the same time, it is not equipped with a mechanism for cleaning the pointer, which leads to certain errors in the use of the mortar rebound test hammer. In order to solve the above problems, a mortar rebound test hammer for house inspection is proposed. Utility Model Content
