Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, and specifically relates to a device for detecting the strength and quality of shear walls. Background Technique

[0002] A shear wall is also called a wind-resistant wall, a seismic wall or a structural wall. It is a wall in a building or structure that mainly bears the horizontal load and vertical load caused by wind load or earthquake action, preventing the structure from shear failure. Also known as a seismic wall, it is generally made of reinforced concrete. It is divided into plane shear walls and tube shear walls. Plane shear walls are used in reinforced concrete frame structures, lift-slab structures, and flat-slab floor systems. During the construction of a wall, wall strength detection is one of the very important steps. During the wall strength detection process, inspectors often use a digital display rebound hammer. The basic principle of the rebound hammer is to drive a heavy hammer with a spring. The heavy hammer impacts the impact rod that is in direct contact with the concrete surface vertically with a constant kinetic energy, causing local concrete to deform and absorb part of the energy. The other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is all 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 the rebound value.

[0003] However, when using the rebound hammer, since it is held by the staff, and the staff needs to perform multiple detections on the same wall surface, frequent operations will not only make the staff tired, but also cause the rebound hammer to be not perpendicular to the wall, thus affecting the detection of the wall strength.
