Description

Technical Field

[0001] The utility model relates to the technical field of building strength detection, in particular to a building strength detection device for a construction project. Background Art

[0002] The main materials used in construction projects are steel bars and concrete. Therefore, during the construction process, it is necessary to conduct quality inspections on concrete blocks to ensure construction safety and quality. After the construction is completed, workers are required to conduct strength inspections on concrete walls to ensure that the strength of the concrete walls reaches the qualified rate. At present, when conducting strength inspections on concrete walls, workers usually hold a rebound hammer to conduct strength inspections on concrete walls. During the inspection process, workers first draw a square frame at the location to be inspected, and then divide the square frame evenly, and then make the final mark in the divided area. The rebound hammer touches the marked points on the wall for multiple times to conduct precise strength inspections of the square, so that the inspection data can be more accurate. Workers hold the rebound hammer for inspection again and again, which takes a long time and has low inspection efficiency. In addition, when inspecting a higher place, the inspector needs to hold the rebound hammer and conduct the inspection with the help of external objects. The height of the inspection is limited by the height of the personnel, and it is difficult to conduct random height inspections.

[0003] According to the Chinese patent application number 202220807375.9, a building concrete strength detection device is proposed. The detection head on the strength detector is inserted into the inside of the card lock, and then the handle is turned. The handle drives the screw to rotate through the connecting rod. The screw and the threaded sleeve rotate relative to each other, and then the thread feed movement is performed. The screw and the threaded sleeve are telescoped. The detection head can be placed in different building measurement positions as needed. The ultrasonic rebound of the equipment is used to detect the concrete strength accordingly, which solves the problem that the strength detection device used for building concrete in the past cannot perform long-distance detection and is not practical enough.

[0004] However, after the listed patent has been improved, although the detection head can be placed at different building measurement positions as needed, and the concrete strength can be detected accordingly through the ultrasonic rebound of the equipment, the detection process still requires workers to use handheld instruments for detection again and again, which takes a long time and has low detection efficiency. For this reason, we propose a construction engineering building strength detection device. Utility Model Content
