[0034] The inner wall of shock insulation support 10 is fixedly connected with a plurality of thin steel plates 7, which can provide vertical support force, the inner wall of shock insulation support 10 is fixedly connected with a plurality of thin rubber sheets 8, which can provide horizontal displacement of shock insulation support 10, the bottom of thin steel plate 7 is in contact with the top of thin rubber sheet 8, and thin steel plate 7 and thin rubber sheet 8 are cross-stacked on the inner wall of shock insulation support 10, which provides horizontal deformation capacity, the inner wall of support base 9 is in contact with the outer wall of a plurality of limit balls 6, and the inner wall of support base 9 is provided with a groove for facilitating the clamping of limit ball 6, so as to facilitate the fixation of the bottom plate box and support base 9 together;
[0035] With reference to Figure 1 , Figure 2 ,Figure 3 and Figure 4 The shock-absorbing assembly comprises a fixing plate 13 for fixing one end of the anti-impact damper 12, which is fixedly connected to the top of the support plate 1 and used for fixing the anti-impact damper 12 on the support plate 1. The inner wall of the fixing plate 13 is rotationally connected with the anti-impact damper 12, which is used for absorbing the impact force received by the floor model. The other end of the anti-impact damper 12 is rotationally connected to the bottom of the other support plate 1. The rotational connection provides a certain deformation capacity for the floor model, further reducing the impact of the impact.
[0036] The bottom of the support plate 1 is fixedly connected with a cross beam 17, which further stabilizes the structure of the building model and connects the subsequent assembly. The bottom of the cross beam 17 is rotationally connected with a shock damper 14, which is used to buffer the incomplete impact and vibration received by the anti-impact damper 12.

Due to the external threads, the rotating rod 3 moves downward while rotating. The rotating rod 3 moves downward while driving the conical block 5 to move downward.

The inner wall of the support seat 9 is provided with a groove, and the limiting ball 6 is clamped into the groove of the support seat 9. The support plate 1 and the support seat 9 are tightly fixed together to prevent errors in the test due to poor fixation during the anti-impact or anti-vibration test.
