[0002] In the inspection of building structures in construction projects, the rebound hammer is the most commonly used non-destructive testing instrument for the compressive strength of concrete structures. When using the rebound hammer to test the strength of concrete structures, in order to ensure the reliability and accuracy of the test results, the axis of the rebound hammer needs to be perpendicular to the concrete wall. However, the rebound hammer is usually operated by the inspector with both hands, and it is difficult to control the axis of the rebound hammer to be perpendicular to the concrete wall, which also leads to large errors in the test results. Utility Model Content

[0003] The purpose of the utility model is to provide a detection device for the structural strength of a building project house. The rebound tester of the detection device can perform a compressive strength test of the concrete structure perpendicular to the concrete wall surface, which is easy to operate and effectively improves the accuracy and reliability of the detection result.

A testing person holds the first handle with one hand and can stick the left wall of the fan-shaped flange to a concrete wall surface to be tested, thereby ensuring the stability of the arc-shaped guide groove body and making the central axis of the arc-shaped guide groove body perpendicular to the concrete wall surface to be tested;

[0006] The inner side of the arc-shaped guide groove body is provided with an arc-shaped sliding groove body for installing a rebound tester, the arc-shaped sliding groove body is coaxial with the arc-shaped guide groove body, the outer side wall of the arc-shaped sliding groove body is in gap contact with the inner side wall of the arc-shaped guide groove body and slides together, and the arc-shaped sliding groove body can move along the central axis of the arc-shaped guide groove body; a baffle is fixedly provided at the right end of the arc-shaped sliding groove body, and a plurality of guide hole plates are provided on the outer side wall of the right end of the arc-shaped guide groove body, which are spaced apart along the circumferential direction, and a guide rod is installed in each guide hole plate, and the right end of each guide rod is fixedly connected to the baffle plate, and the left end of each guide rod is threadedly connected to a limiting nut to prevent the guide rod from falling off the guide hole plate; under the guiding action of the plurality of guide rods, the arc-shaped sliding groove body can be ensured to move along the central axis of the arc-shaped guide groove body in the arc-shaped guide groove body, and the arc-shaped sliding groove body can be prevented from rotating around the central axis;

[0007] When using the testing device, the rebound tester can be inserted into the arc-shaped sliding groove body. The testing personnel holding the first handle with one hand can press the fan-shaped flange against the concrete wall to be tested, so that the impact rod of the rebound tester is aimed at the test point. At this time, the axis of the rebound tester is perpendicular to the concrete wall to be tested, and the other hand can push the baffle plate to make the arc-shaped sliding groove body move to the left along the central axis of the arc-shaped guide groove body in the arc-shaped guide groove body. The baffle plate can push the rebound tester to move to the left together with the arc-shaped sliding groove body, and the impact rod of the rebound tester hits the concrete wall to measure the compressive strength of the concrete wall; after the measurement of one point is completed, the impact rod of the rebound tester is controlled to hit the concrete wall again to reset the impact rod of the rebound tester, and the testing personnel hold the first handle to move the testing device to the next point to continue testing; using the testing device, the rebound tester can be perpendicular to the concrete wall to test the compressive strength of the concrete structure, which is easy to operate and can improve the accuracy and reliability of the test results.

[0010] Furthermore, each of the guide rods is provided with a spring, and the two ends of the spring are respectively against the guide hole plate and the baffle plate. In the initial state, the spring is in a naturally extended state. When the baffle plate is pushed to move to the left, the spring can be compressed. After releasing the hand, the arc-shaped sliding groove body can automatically move to the right under the action of the spring's rebound force. In particular, after the rebound hammer's impact rod hits the concrete wall for the first time and the measurement is completed, the rebound hammer can detach from the concrete wall along with the arc-shaped sliding groove body, and push the arc-shaped sliding groove body again, so that the rebound hammer's impact rod hits the concrete wall again, and the rebound hammer's impact rod can be reset, which is convenient for quick measurement and resetting of the rebound hammer's impact rod.

[0011] Furthermore, a protective pad is fixedly installed on the left side wall of the baffle, which can help to provide shock-absorbing protection for the rebound instrument; the protective pad is made of elastic rubber material or elastic silicone material. When the rebound instrument is inserted between the fan-shaped card plate and the baffle, the right end of the rebound instrument is first pressed against the protective pad and squeezed, and then the left end of the rebound instrument is inserted into the fan-shaped card plate. After releasing the hand, the rebound instrument can be pressed tightly under the elastic force of the protective pad, thereby improving the stability of the rebound instrument. The structural principle is similar to that of the tail of a dry cell being locked with a spring.

[0012] Furthermore, the arc-shaped guide groove body, the fan-shaped flange, the first handle, the arc-shaped sliding groove body, the fan-shaped clamping plate and the baffle are all made of plastic, which is light in weight and easy to operate.

[0013] Furthermore, a second handle is fixedly mounted on the right side wall of the baffle, and the operator can push and pull back the arc-shaped sliding groove body by holding the second handle with his hand, which is convenient for operation.

The testing personnel can hold the first handle with one hand to press the fan-shaped flange against the concrete wall to be tested, so that the impact rod of the rebound tester is aimed at the test point. At this time, the axis of the rebound tester is perpendicular to the concrete wall to be tested. The other hand can push the baffle plate to make the arc-shaped sliding groove body move to the left along the central axis of the arc-shaped guide groove body in the arc-shaped guide groove body.
