Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a shock-absorbing bottom plate for assembled buildings. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. The building components and accessories are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods. Prefabricated buildings are not a whole. When subjected to large forces, they are prone to displacement, bending, deformation, collapse and other dangers. When the force is uneven, they are more likely to be damaged or broken.

[0003] Chinese patent document CN212772934U discloses a shock-absorbing base plate for assembled buildings, including a lower base plate, a shock-absorbing device, a pressure-reducing device, an upper base plate, and an anti-skid pad. Shock-absorbing devices are respectively installed at the four corners of the upper end of the lower base plate, and pressure-reducing devices are respectively installed on the left and right sides of the middle of the lower base plate. The upper base plate is fixed to the upper ends of the shock-absorbing device and the pressure-reducing device, and the anti-skid pad is fixed to the upper end of the upper base plate. The above-mentioned shock-absorbing base plate for assembled buildings has shortcomings. Although the device can achieve shock absorption of the base plate, it has limitations. The setting only uses springs for buffering and shock absorption, which makes the shock absorption effect of the base plate poor. Secondly, the telescopic rod is easily deformed due to impact during use, further reducing the shock absorption effect of the base plate.

[0004] Therefore, in order to solve such problems, we propose an assembled building shock-absorbing base plate. Utility Model Content

[0024] Reference Figure 1-6The utility model provides an embodiment: an assembled building shock-absorbing base plate, comprising a lower base plate 1, a mounting groove 101 is opened at the upper end of the lower base plate 1, a first shock-absorbing assembly 2 is arranged inside the lower base plate 1, and the first shock-absorbing assembly 2 comprises a pillar 21, a first push block 22 is fixedly connected to the lower end of the pillar 21, two non-adjacent side walls of the first push block 22 are slidably connected to the second push block 23, the second push block 23 is slidably connected to the mounting groove 101, a side wall of the second push block 23 away from the other second push block 23 is fixedly connected to a second shock-absorbing damper 24, a side wall of the second shock-absorbing damper 24 is movably sleeved with a second spring 25, one end of the second shock-absorbing damper 24 away from the second push block 23 is fixedly connected to the side wall of the mounting groove 101, one end of the pillar 21 away from the first push block 22 is fixedly connected to a connecting plate 26, and one end of the connecting plate 26 away from the pillar 21 is fixedly connected to the upper base plate 12.

[0025] In this arrangement, the upper base plate 12 transmits the impact force to the pillar 21 through the connecting plate 26, so that the pillar 21 drives the first push block 22 to move vertically and linearly, so that the first push block 22 pushes the two second push blocks 23 to slide in the installation groove 101, so that the second push blocks 23 squeeze the second shock-absorbing damper 24 and the second spring 25. The cooperation between the first push block 22 and the two second push blocks 23 can convert part of the pressure into friction force consumption, and at the same time, the second shock-absorbing damper 24 and the second spring 25 are used to absorb the energy generated by the impact, thereby greatly reducing the pressure on the upper and lower sides.

[0026] The upper surface of the lower base plate 1 is provided with a second shock absorbing assembly 11, and the second shock absorbing assembly 11 includes a first mounting plate 111, which is fixedly connected to the upper surface of the lower base plate 1, and a first shock absorbing damper 112 is fixedly connected to the upper end of the first mounting plate 111, and a first spring 113 is movably sleeved on the side wall of the first shock absorbing damper 112, and a second mounting plate 114 is fixedly connected to the end of the first shock absorbing damper 112 away from the first mounting plate 111, and the second mounting plate 114 is fixedly connected to the lower end of the upper base plate 12, and is used for utilizing the first shock absorbing damper 112 and the first spring 113 in the second shock absorbing assembly 11 to secondary absorb the energy generated by the impact, thereby increasing the shock absorbing effect.

[0027] A buffer groove 102 is provided inside the lower base plate 1 . The buffer groove 102 is located outside the mounting groove 101 and is used to prevent the first push block 22 from directly hitting the inner bottom wall of the mounting groove 101 during vertical linear motion.

[0028] A rubber plate 13 is fixedly connected to the upper end of the upper base plate 12 , and is used to perform a first buffering and energy absorption by using the rubber plate 13 , and at the same time, to increase friction by using the rubber plate 13 .

The end of the telescopic cylinder 3 away from the lower base plate 1 is fixedly connected to the lower end of the upper base plate 12, which is used to protect the second shock absorbing assembly 11 and prevent the second shock absorbing assembly 11 from being damaged by impact.

[0030] The first push block 22 is in the shape of an isosceles trapezoid, and the second push block 23 is in the shape of an isosceles right-angled trapezoid, so that the first push block 22 can simultaneously push the two second push blocks 23 to slide in the installation groove 101 .

The first push block 22 and the two second push blocks 23 cooperate to convert part of the pressure into friction consumption. At the same time, the second shock-absorbing damper 24 and the second spring 25 are used to absorb the energy generated by the impact, thereby greatly reducing the pressure on the upper and lower sides. Then, the first shock-absorbing damper 112 and the first spring 113 in the second shock-absorbing assembly 11 are used to absorb the energy generated by the impact for a second time to increase the shock-absorbing effect.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
