Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering testing equipment, in particular to a building earthquake resistance detection device. Background Art

[0002] After the completion of a building, it is necessary to test the seismic resistance of the building. The seismic resistance of a building is directly related to the strength of the concrete, so the testing of the seismic performance of the building needs to be done with the help of a rebound hammer. The basic principle of the rebound hammer is to use a spring to drive a heavy hammer. The heavy hammer hits the impact rod in vertical contact with the concrete surface with a constant kinetic energy, causing the local concrete to deform and absorb part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebounds to the maximum distance, and the instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial value of the spring).

[0003] During the existing seismic testing of buildings, the seismic performance of the walls and ceilings of the buildings are usually tested manually using handheld rebound testers. However, since the heights of the walls and ceilings of different buildings are different, manual climbing is required for testing. The overall process is relatively complicated, time-consuming and labor-intensive. In addition, frequent manual climbing for testing poses a major safety hazard and is difficult to meet actual usage needs. Utility Model Content

[0022] In this embodiment, the first motor 3 drives the screw rod 4 to rotate, thereby causing the sliding frame 5 to slide up and down in the fixed frame 2, so as to adjust the height of the rebound tester 6 so that it can detect walls of different heights. At the same time, the third motor 26 drives the third rotating shaft 25 to rotate, so that the third rotating seat 18 can drive the mounting seat 19 to rotate, so that the rebound tester 6 is vertically facing the ceiling, thereby realizing seismic detection of the building ceiling, thereby reducing the difficulty of maintenance work, saving labor and time costs, avoiding safety hazards, and meeting different usage requirements.

[0023] Example 2: Figure 1-Figure 4 As shown, a first fixing plate 7 is provided on one side of the two fixing frames 2, a first rotating shaft 8 is provided on the side where the two first fixing plates 7 are close to each other, a second motor 9 is provided on one side of a single first fixing plate 7, an output end of the second motor 9 movably passes through the single first fixing plate 7 and is connected to the first rotating shaft 8, two first rotating seats 10 are fixedly connected to the outer side of the first rotating shaft 8, one end of the first rotating seat 10 is connected to a hydraulic telescopic rod 11, one end of the hydraulic telescopic rod 11 is connected to a second rotating seat 12, a first ear seat 13 is provided on the outer side of the second rotating seat 12, a second rotating shaft 14 is provided on the inner side of the first ear seat 13, and a second rotating shaft 15 is provided on the inner side of the second rotating seat 12. One end of the rotating shaft 14 passes through the single first ear seat 13 and is connected to the handwheel 15, the bottom of the first ear seat 13 is fixedly connected to the anti-slip bottom plate 16, a second fixed plate 20 is provided at one end of the top of the mounting seat 19, and two third fixed plates 21 are provided at the other end of the top of the mounting seat 19.

In this process, the hand wheel 15 is twisted to rotate the anti-skid bottom plate 16 until the anti-skid bottom plate 16 is against the ground to support the device body, and then the cylinder 24 is started to push the mounting plate 23 to slide on the guide rod 22, so that the rebound tester 6 is against the wall, and the seismic performance of the wall is tested. Finally, when it is necessary to test the ceiling, the third motor 26 is started to drive the third rotating shaft 25 to drive the third rotating seat 18 to rotate until the rebound tester 6 is perpendicular to the ceiling. At this time, the cylinder 24 is started again to push the rebound tester 6 against the ceiling, and the seismic performance of the ceiling can be tested, thereby completing the use of the building seismic detection device.
