Abstract

The utility model discloses a high-efficiency concrete slab hardness detection device for construction, which comprises a bottom plate, and two L-shaped struts are symmetrically and fixedly connected with the top surface of the bottom plate. The hydraulic cylinder exerts force to drive the detection rod down to detect the hardness of the concrete slab. The setting of the second spring can effectively play a buffering role to avoid direct exertion and damage to the output end of the hydraulic cylinder. After the inspection, when the next inspection is required, start the hydraulic cylinder to shorten the operation, so that the trapezoidal slider will push the sawtooth block to one side in the process of continuing to rise vertically, and then drive the concrete slab fixedly connected on the worktable to the other side. Move it to just below the detection rod, and then use the same principle as above to detect the next place of the concrete, so that when the concrete slab needs to be inspected in multiple places, it can avoid the need for the staff to continuously move the concrete slab, and also The tedious fixing operation of the concrete plate is avoided, thereby effectively improving the work efficiency.
