A kind of environmental calibration device for detecting the thickness of steel protective layer of concrete structure

Abstract

The present application relates to an environmental calibration device for detecting the thickness of a steel bar protective layer of a concrete structure. The telescopic frame of the bracket and the drive assembly arranged on the support bracket to drive the detector body to move along the length direction of the support bracket, the detector body can be detachably fixed on the drive assembly, and the drive assembly includes a drive assembly along the length of the support bracket The polished rod fixed on the bearing bracket in the direction, the screw rod connected to the bearing bracket in parallel with the polished rod, the moving block arranged between the polished rod and the screw rod, and the drive motor fixed on the bearing bracket and coaxially connected with the screw rod, The moving block is slidably connected with the polished rod, and is threadedly connected with the screw, and a connecting assembly for connecting the detector body is provided on the moving block. The present application has the effect of facilitating the rapid detection of wall surfaces at different positions by the staff.

Description

technical field [0001] The application relates to the technical field of detection of the thickness of the protective layer of steel bars in concrete structures, and in particular to an environmental calibration device for detecting the thickness of the protective layer of steel bars in concrete structures. Background technique [0002] Reinforcing bar protection layer is the concrete between the outer edge of the stressed steel bar and the surface of the component in the structural concrete; the concrete between the outer edge of the reinforcement frame stirrup, the horizontal bar and the spiral bar to the component; when the thickness of the reinforcement bar protection layer is too small, it is thinner. When the thickness is too large, the flexural bearing capacity, crack control performance and stiffness will be reduced. It is of great significance to control and measure the protective layer to protect the steel bar from the corrosion of the external environment, improve...

Problems solved by technology

[0004] For the related technologies mentioned above, when it is necessary to detect a higher wall, the staff need to use the escalator to increase the height, and then move the detector in a straight line, which not only increases the labor intensity of the staff, but also lowers the detection efficiency
