Description

Technical Field

[0001] The utility model relates to the technical field of building foundation vibration reduction, and specifically relates to a reinforcement and vibration reduction device for a prefabricated building foundation. Background Technique

[0002] An earthquake is a general term for the crustal vibration phenomenon caused by endogenous geological action and exogenous geological action. Buildings are generally built on rock and soil foundations. During an earthquake, the seismic waves propagating in the rock and soil cause the foundation soil to vibrate. The vibration causes additional deformation and strength change of the soil. When the strength of the foundation soil cannot withstand the stress generated by the foundation vibration deformation, the foundation soil will lose the ability to support the building, resulting in foundation failure. In severe cases, earthquake disasters such as surface fracture, collapse, sand liquefaction, and soft soil seismic subsidence may occur. A prefabricated building refers to a building assembled on the construction site with prefabricated components. This type of building mostly uses detachable connections for connectors, has a fast construction speed, saves labor, and can improve the building quality, and can meet the construction needs of modern civilized ecological cities. However, the existing technology has the following deficiencies when in use:

[0003] When the foundation is vibrated, the anti-vibration effect is poor, the foundation columns may shift, which may cause casualties and property losses, and there are certain safety hazards in actual use.

[0004] Therefore, there is an urgent need for a reinforcement and vibration reduction device for a prefabricated building foundation to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to address the problem that currently exists, namely, when the foundation is vibrated, the anti-vibration effect is poor, the foundation columns may shift, which may cause casualties and property losses, and there are certain safety hazards in actual use.

[0006] In order to achieve the above-mentioned invention purpose, the utility model provides the following technical solutions:

[0007] A reinforcement and vibration reduction device for a prefabricated building foundation to improve the above problems.

[0008] Specifically, this application is as follows:

[0009] An anti-vibration device for strengthening the foundation of a prefabricated building, comprising a base column, on which four first connecting plates arranged in a circular pattern are fixedly connected. One end of each first connecting plate away from the base column is provided with an installation clip, and a fixing block is fixedly connected to the installation clip. At the four corners of the bottom of the fixing block, first damping pads are fixedly connected. At the bottom of each first damping pad, a guide rod is fixedly connected. A guide tube is slidably sleeved on the guide rod. At the bottom of the guide tube, a second damping pad is fixedly connected. A buffer spring sleeved outside the guide tube is fixedly connected between the first damping pad and the second damping pad. The bottoms of the four second damping pads are commonly fixedly connected to a base. At the center of the bottom of the fixing block, a pressure rod is fixedly connected. A rubber cushion is fixedly connected to the top of the base. A placement cavity is formed in the rubber cushion, and a buffer air cushion and industrial sponge are arranged in the placement cavity.

[0010] As a preferred technical solution of the present application, the first connecting plate and the installation clip are fixed by a first bolt.

[0011] As a preferred technical solution of the present application, two of the first connecting plates are provided with reinforcement plates, and the number of the reinforcement plates is four.

[0012] As a preferred technical solution of the present application, the base is provided with a second bolt.

[0013] As a preferred technical solution of the present application, the industrial sponge is sleeved outside the buffer air cushion.

[0014] As a preferred technical solution of the present application, the pressure rod is directly above the buffer air cushion.

[0015] As a preferred technical solution of the present application, the reinforcement plates are arranged in a circular pattern around the base column.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] In the solution of the present application:

[0018] 1. By providing a first damping pad, a guide rod, a guide tube, a second damping pad, a buffer spring, a pressure rod, a rubber gasket, a placement cavity, a buffer air cushion, and industrial sponge, when the base column is vibrated, the fixed block and the pressure rod will move downward. The buffer spring will be compressed and deformed under the vibration force. The first damping pad and the second damping pad can absorb part of the vibration energy and play a certain vibration reduction effect. When the pressure rod moves downward, it will squeeze the buffer air cushion in the placement cavity. The buffer air cushion can absorb part of the vibration force. When the buffer air cushion deforms, it will cause the industrial sponge to be pulled outward and deformed, so that the rubber gasket also deforms to a certain extent. Through the combined use of the industrial sponge and the rubber gasket, part of the generated vibration force can be absorbed again, achieving a better vibration reduction effect, and solving the problem that in the prior art, when the foundation is vibrated, the anti-vibration effect is poor, which may cause casualties and property losses to humans, and there are certain safety hazards in actual use.

[0019] 2. By providing a first connecting plate, a mounting clip, and a first bolt, the first connecting plate is fixed by the first bolt, thereby playing a certain reinforcing effect on the base column and preventing the base column from shifting when vibrated, solving the problem that in the prior art, when the foundation is vibrated, the base column may shift.

[0031] Such as Figures 1-4As shown in the figure, a reinforcement and vibration reduction device for the foundation of a prefabricated building proposed in this embodiment includes a base column 1. Four first connecting plates 2 arranged in a circular pattern are fixedly connected to the base column 1. An installation clip 3 is provided at one end of the first connecting plate 2 away from the base column 1. A fixing block 4 is fixedly connected to the installation clip 3. First damping pads 5 are fixedly connected to the four corners of the bottom of the fixing block 4. A guide rod 6 is fixedly connected to the bottom of the first damping pad 5. A guide tube 7 is slidably sleeved on the guide rod 6. A second damping pad 8 is fixedly connected to the bottom of the guide tube 7. A buffer spring 9 sleeved outside the guide tube 7 is fixedly connected between the first damping pad 5 and the second damping pad 8. The four second damping pads 8 are fixedly connected to a base 10 at the bottom. A pressure rod 11 is fixedly connected to the center of the bottom of the fixing block 4. When the base column 1 is vibrated, the fixing block 4 and the pressure rod 11 will move downward. The buffer spring 9 will be compressed and deformed under the vibration force. The first damping pad 5 and the second damping pad 8 can absorb part of the vibration energy and play a certain vibration reduction effect. A rubber cushion 12 is fixedly connected to the top of the base 10. A placement cavity 13 is provided in the rubber cushion 12. A buffer air cushion 14 and industrial sponge 15 are provided in the placement cavity 13. When the pressure rod 11 moves downward, it will squeeze the buffer air cushion 14 in the placement cavity 13. The buffer air cushion 14 can absorb part of the vibration force. When the buffer air cushion 14 deforms, it will cause the industrial sponge 15 to be pulled outward and deformed, so that the rubber cushion 12 also produces a certain deformation. Through the combined use of the industrial sponge 15 and the rubber cushion 12, part of the generated vibration force can be absorbed again, achieving a better vibration reduction effect.

[0032] As Figure 2 and Figure 3 shown, the first connecting plate 2 and the installation clip 3 are fixed by a first bolt 16. By fixing the first connecting plate 2 with the first bolt 16, a certain reinforcement effect is achieved on the base column 1, preventing the base column 1 from shifting when vibrated.

[0033] As Figure 1 shown, four reinforcement plates 17 are installed on two first connecting plates 2, achieving a reinforcement effect on the base column 1 again.

[0034] As Figure 1 shown, a second bolt 18 is provided on the base 10, and the base 10 is fixed by the provided second bolt 18.

[0035] As Figure 4 shown, the industrial sponge 15 is sleeved outside the buffer air cushion 14. When the buffer air cushion 14 deforms, it will cause the industrial sponge 15 to be pulled outward and deformed, so that the rubber cushion 12 also produces a certain deformation. Through the combined use of the industrial sponge 15 and the rubber cushion 12, part of the generated vibration force can be absorbed again, achieving a better vibration reduction effect.

[0036] AsFigure 2 and Figure 4 As shown in Figure 4 , the compression bar 11 is located directly above the buffer air cushion 14. When the base column 1 is vibrated, the fixed block 4 and the compression bar 11 will move downward. When the compression bar 11 moves downward, it will squeeze the buffer air cushion 14 in the placement cavity 13, and the buffer air cushion 14 can absorb part of the vibration force.

[0037] As Figure 1 shown in Figure 1 , the reinforcement plates 17 are arranged in a circular pattern around the base column 1.

[0038] Specifically, when the present reinforcement and vibration reduction device for the foundation of an assembled building is in use: the base 10 is fixed by the second bolt 18 provided. When the base column 1 is vibrated, the fixed block 4 and the compression bar 11 will move downward. The buffer spring 9 will be compressed and deformed under the vibration force. The first damping pad 5 and the second damping pad 8 can absorb part of the vibration energy and play a certain vibration reduction effect. When the compression bar 11 moves downward, it will squeeze the buffer air cushion 14 in the placement cavity 13, and the buffer air cushion 14 can absorb part of the vibration force. When the buffer air cushion 14 deforms, it will cause the industrial sponge 15 to be pulled outward and deformed, so that the rubber gasket 12 also deforms to a certain extent. Through the combined use of the industrial sponge 15 and the rubber gasket 12, part of the generated vibration force can be absorbed again, playing a better vibration reduction effect. The first connecting plate 2 is fixed by the first bolt 16, so as to play a certain reinforcement effect on the base column 1 and prevent the base column 1 from shifting when vibrated.

[0039] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
