The so-called effects refer to various factors that can cause internal forces and deformations in the system, such as loads, earthquakes, temperature changes, and foundation settlement. The durability, earthquake resistance, safety, and space use performance of houses of various structures are different. As a place for people to live, houses must have a certain earthquake resistance. By conducting earthquake resistance tests on the load-bearing beams of houses, the harm caused by earthquakes can be reduced.

Through the slider 3 on the adjusting part 2, with the cooperation of the slide groove 4, the adjusting part 2 can be moved horizontally, so as to adjust the position of the detection part 5, which is convenient for detecting different positions of the load-bearing beam. After the adjustment is completed, the pull rod 8 is released, and when the spring 10 resets and extends itself, the pull rod 8 is pushed to reset, so that the friction block 9 and the limit groove 6 are in contact, the adjusting part 2 is fixed, and the displacement of the detection part 5 is avoided, thereby improving practicality.

[0032] Reference Figure 2 and Figure 3 The lower surface of the detection member 5 is fixed with a driving motor 11 by bolts, and the power output shaft of the driving motor 11 passes through the detection member 5 and is connected with a gear 12. The driving motor 11 on the detection member 5 can drive the gear 12 to rotate, thereby driving the detection mechanism to operate; one side of the gear 12 is meshedly connected with a gear rod 13, and the end of the gear rod 13 is slidably inserted with a guide rod 17 fixedly connected to the inner wall of the detection member 5. The guide rod 17 is arranged to ensure the stability of the gear rod 13 during movement and avoid the gear rod 13 from deflecting during movement; the upper surface of the gear rod 13 is fixedly connected with a fixing rod 14, and a baffle 15 is fixed at the end of the fixing rod 14.

By simulating the house shaking force generated by the earthquake, the seismic performance of the house structure is detected.

[0033] Reference Figure 1 , Figure 2 and Figure 4 , adjusting bolts 18 are installed at both ends of the tool base 1, and the end of the adjusting bolt 18 is sleeved with a bearing 19. A clamping plate 20 is fixed to the outer wall of the bearing 19.

The shaking force of the house caused by the earthquake is simulated to detect the seismic performance of the house structure. When it is necessary to detect different positions of the load-bearing beam, the pull rod 8 on the mounting shell 7 can be manually pulled to separate the friction block 9 from the limit groove 6 on the tool base 1, thereby releasing the fixation of the adjusting member 2. Then, the slider 3 on the adjusting member 2 can be used to move the adjusting member 2 horizontally with the cooperation of the slide groove 4, so as to adjust the position of the detection member 5, which is convenient for detecting different positions of the load-bearing beam. After the adjustment is completed, the pull rod 8 is released. When the spring 10 resets and stretches itself, the pull rod 8 is pushed to reset, so that the friction block 9 contacts the limit groove 6, and the adjusting member 2 is fixed to avoid displacement of the detection member 5, thereby improving practicality.
