Description

Technical Field

[0001] The utility model belongs to the technical field of building shock absorption, and relates to a shock absorption structure, in particular to a shock absorption structure of an assembled building. Background Art

[0002] Prefabricated construction is a construction method that integrates the main components of a building's structural system, exterior envelope, equipment and piping systems, and interior systems using prefabricated components. Its core principle is to produce prefabricated components and accessories in a factory and then transport them to the construction site for assembly, thereby achieving rapid and efficient construction. The shock-absorbing structure of prefabricated buildings effectively reduces the impact of earthquakes on the building, improving its overall seismic resistance and safety.

[0003] For example, the patent publication number CN219298460 U describes a shock-absorbing structure for an assembled building, in which the solution described is as follows: a group of support rods, a first slider, and a first shock-absorbing spring are arranged between the base plate and the support platform, and a rotating shaft is arranged between the two ends of the support rod and the first slider and the support platform, so that when the building vibrates, the support platform generates downward pressure, so that the support rod drives the first slider to squeeze the first shock-absorbing spring, which can effectively disperse the pressure of the upper vibration to both sides, achieve pressure buffering, and then achieve shock absorption.

[0004] The above case has the problem of poor shock absorption effect. Since prefabricated buildings are prefabricated in advance and then assembled, there is often a problem of poor shock absorption effect after construction is completed, which leads to the collapse of the prefabricated building. The shock absorption structure cannot perform multiple shock absorption, which makes the prefabricated building have safety hazards. Utility Model Content

[0025] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1 and 2 As shown, this embodiment provides a shock-absorbing structure for an assembled building, including a shock-isolating plate 1 , a shock-absorbing block 2 and a shock-absorbing assembly 3 .

[0028] The shock absorbing block 2 is located below the shock isolating plate 1 , and a plurality of plate damping springs 21 are provided between the shock isolating plate 1 and the shock absorbing block 2 .

[0029] The shock-absorbing assembly 3 includes a cushion 31, a plurality of cushion damping springs 32, and a plurality of damping telescopic rods 33. The shock-absorbing block 2 is hollow, and the cushion 31 is disposed within the shock-absorbing block 2. The plurality of cushion damping springs 32 are disposed between the cushion 31 and the bottom of the shock-absorbing block 2. A plurality of damping telescopic rods 33 are disposed between the cushion 31 and the isolation plate 1. The fixed ends of the damping telescopic rods 33 are fixed to the cushion 31, and the telescopic ends extend upward through the shock-absorbing block 2 and are fixed to the bottom of the isolation plate 1.

[0030] The buffer pad 31 is an arc-shaped surface with a concave center, so that it can better decompose impact force and vibration.

[0031] The shock-absorbing block 2 is made of elastic material, such as rubber, so that it can resist the vertical and horizontal loads generated by an earthquake and reduce the impact force and vibration suffered by the building during an earthquake.

[0032] The number of the plate damping springs 21 and the damping telescopic rods 33 are equal and correspond one to one. The plate damping springs 21 are sleeved on the outside of the corresponding damping telescopic rods 33 .

[0033] In this embodiment, the vibration force is decomposed to the shock-absorbing block 2 through the plate damping spring 21, and then the damping telescopic rod 33 forms a supporting force with the shock isolation plate 1. When the vibration force is too large, the damping telescopic rod 33 will be squeezed, and the damping telescopic rod 33 will lead the impact force to the buffer pad 31. Then the buffer pad 31 is squeezed, causing its arc-shaped surface to deform, thereby further decomposing the impact force, and the pad damping spring 32 at its bottom forms a counter-support, further reducing the impact force, and then decomposing the impact force to the bottom of the shock-absorbing block 2.

[0034] Example 2

[0035] like Figures 1 to 3 As shown, this embodiment provides a shock-absorbing structure for an assembled building, which is substantially the same in structure as the embodiment, except that it further includes a buffer assembly 4. The buffer assembly 4 is disposed above the isolation plate 1 for buffering and protecting the isolation plate 1.

[0036] The buffer assembly 4 includes an upper shock-absorbing rod 41, a lower shock-absorbing rod 42, a plurality of support rods 43 and a plurality of connecting rods 44. The lower shock-absorbing rod 42 is arranged above the shock-isolating plate 1, and the upper end is slidably connected to the inside of the upper shock-absorbing rod 41. A plurality of support rods 43 are arranged around the upper shock-absorbing rod 41, the upper end of the support rod 43 is rotatably connected to the side of the upper shock-absorbing rod 41, and the lower end is slidably connected to the top of the shock-isolating plate 1. The number of connecting rods 44 and support rods 43 is equal and one-to-one corresponding. A plurality of connecting rods 44 are arranged around the lower shock-absorbing rod 42, one end of the connecting rod 44 is rotatably connected to the side of the lower shock-absorbing rod 42, and the other end is rotatably connected to the side of the corresponding support rod 43.

[0037] The upper shock absorbing rod 41 presses the lower shock absorbing rod 42 downward, and the lower shock absorbing rod 42 forms an antagonistic support for the upper shock absorbing rod 41. At the same time, the downward movement of the upper shock absorbing rod 41 will drive the support rod 43 to move around, and the restriction of the connecting rod 44 provides it with antagonistic support.

[0038] Specifically, the top of the seismic isolation plate 1 has a plurality of limiting grooves 11 corresponding to the support rods 43. The plurality of limiting grooves 11 are scattered around with the lower shock absorbing rod 42 as the center. The setting direction of each limiting groove 11 is consistent with the sliding trajectory of the lower end of the corresponding support rod 43. A slider 431 matching the limiting groove 11 is fixed to the lower end of the support rod 43, and the slider 431 is slidably connected in the corresponding limiting groove 11. A rod groove damping spring 45 is provided between the slider 431 and the outer end in the limiting groove 11.

[0039] When the support rod 43 moves around, it drives the slider 431 to slide in the limiting groove 11, squeezing the rod groove damping spring 45, and the rod groove damping spring 45 forms an opposing support, thereby reducing the impact force during vibration and preventing the upper shock-absorbing rod 41 from falling again.

[0040] Furthermore, a rod plate damping spring 46 is provided between the lower shock-absorbing rod 42 and the isolation plate 1, so that the lower shock-absorbing rod 42 can move downward and form an auxiliary counter-support. A rod-rod damping spring 47 is provided between the lower shock-absorbing rod 42 and the upper shock-absorbing rod 41. A tension spring 48 is provided between the slider 431 and the inner end of the limiting groove 11. When the upper shock-absorbing rod 41 moves, it drives the lower shock-absorbing rod 42. When the lower shock-absorbing rod 42 squeezes the rod plate damping spring 46, the rod plate damping spring 46 forms an upward counter-force, thereby causing the lower shock-absorbing rod 42 to squeeze the rod-rod damping spring 47 upward. Subsequently, under the tension of the tension spring 48, the tension spring 48 drives the support rod 43 close to the upper shock-absorbing rod 41, thereby forming a better support, and the rod-rod damping spring 47 rebounds upward to form a counter-support for the upper shock-absorbing rod 41.

[0041] The present shock-absorbing structure performs the initial shock absorption through the upper shock-absorbing rod 41, and then the upper shock-absorbing rod 41 presses the lower shock-absorbing rod 42 downward, and the lower shock-absorbing rod 42 forms an antagonistic support for the upper shock-absorbing rod 41. As the upper shock-absorbing rod 41 moves downward, it drives the support rod 43 to move around. The movement of the support rod 43 drives the slider 431 to slide in the limit groove 11, and then squeezes the rod groove damping spring 45. The rod groove damping spring 45 forms an antagonistic support, thereby reducing the impact force during vibration and preventing the upper shock-absorbing rod 41 from falling again. When the impact force is too large, the isolation The vibration plate 1 is squeezed, and then the vibration force is decomposed to the shock-absorbing block 2 through the plate damping spring 21. Then the damping telescopic rod 33 forms a supporting force with the vibration isolation plate 1. When the vibration force is too large, the damping telescopic rod 33 will be squeezed, and the damping telescopic rod 33 will lead the impact force to the buffer pad 31. Then the buffer pad 31 is squeezed, causing its arc-shaped surface to deform, thereby further decomposing the impact force, and the pad damping spring 32 at its bottom forms a counter-support, further reducing the impact force, and then decomposing the impact force to the bottom of the shock-absorbing block 2, thereby forming multiple shock-absorbing protection.
