Steel bars have strong tensile and compressive strength, while concrete has only high compressive strength but low tensile strength. Combining the two significantly improves the material's mechanical properties.

[0003] The existing patent (publication number: CN215727453U) discloses a non-destructive testing device for reinforced concrete structures, which relates to the field of reinforced concrete testing. The non-destructive testing device for reinforced concrete structures includes a wall-mounted plate, a rebound tester body, and a clamping and fixing mechanism. The top of the wall-mounted plate is fixedly connected to two sets of vertical guide rails, and a sliding clamping seat is slidably connected between the two sets of vertical guide rails. The top of the sliding clamping seat is provided with a cylindrical groove, the back of the sliding clamping seat is provided with a square groove, the front of the sliding clamping seat is fixedly connected to a pressing handle, and the top of the wall-mounted plate is provided with a detection port. The non-destructive testing device for reinforced concrete structures can ensure that the rebound tester body is perpendicular to the wall during testing, thereby ensuring accurate test data for reinforced concrete walls and good test results.

By providing a visual window at the top of the sliding clamping seat, the staff can read the test data of the rebound hammer through the visual window, avoiding the rebound hammer test data from being blocked, providing convenience for the detection operation, and improving the practicality of the detection device.

[0008] Furthermore, a screw rod is rotatably inserted inside the sliding clamping seat, a threaded tube is threadedly connected to the outer circumference of the screw rod, and a positioning plate is fixedly connected to the left side of the threaded tube.

[0009] According to the above solution, the threaded tube and the positioning plate are moved by rotating the screw rod, thereby completing the positioning operation of the rebound hammer, which facilitates the positioning or disassembly of the rebound hammer.

[0010] Furthermore, the positioning plate has an arc-shaped structure, and a first protective sheet is fixedly connected to the inner wall of the positioning plate. The first protective sheet is made of rubber, and the inner wall of the first protective sheet is provided with anti-slip grooves arranged at equal distances.

[0011] Through the above solution, the rebound hammer is protected to avoid damage to the rebound hammer during the positioning process, and the friction between the rebound hammer and the first protective sheet is increased, thereby improving the stability of the rebound hammer positioning.

[0012] Furthermore, a second protective sheet is fixedly connected to the inner wall of the cylindrical groove, the second protective sheet is made of rubber, and the inner wall of the second protective sheet is provided with anti-slip grooves arranged at equal intervals.

[0014] Furthermore, four springs are fixedly connected to the front side of the abutting plate, and the front side of each spring is fixedly connected to the back side of the sliding clamping seat.

[0015] Through the above solution, the spring applies a reaction force to the sliding clamping seat, so that the sliding clamping seat can automatically move back after the detection is completed, thereby facilitating continuous detection operations.

[0016] Furthermore, a collar is fixedly sleeved on the outer circumferential surface of each column, and the inner surface of the collar contacts the front surface of the sliding clamping seat.

[0017] Through the above solution, the sliding clamping seat is restricted to prevent the sliding clamping seat from falling off the column, thereby improving the stability of the sliding clamping seat movement.

[0018] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the screw rod, and the outer circumferential surface of the limiting ring is rotatably connected to the interior of the sliding clamping seat.

[0020] Furthermore, two limiting blocks are fixedly connected to the outer circumference of the threaded tube, two limiting grooves are provided inside the sliding clamping seat, and the outer surfaces of the limiting blocks are slidably connected to the sliding clamping seat through the limiting grooves.

[0021] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating with the screw rod, so that the threaded tube is always moved laterally, thereby improving the stability of the threaded tube movement.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The reinforced concrete structure nondestructive testing device, by arranging a positioning plate on the side of the cylindrical groove and providing a viewing window on the top of the sliding clamping seat, enables workers to read the test data of the rebound hammer through the viewing window, thereby preventing the test data of the rebound hammer from being blocked, providing convenience for the testing operation, and improving the practicality of the testing device. It solves the problem that the existing testing device will cover the outer circumferential surface of the rebound hammer when the rebound hammer is installed, making it inconvenient to read the test data of the rebound hammer during the testing process, causing inconvenience to the testing personnel and reducing the practicality of the testing device.
