Abstract

The present invention provides a three-dimensional vibration dual-control rubber bearing, wherein the connecting plate and the thick rubber block are arranged between the upper flange plate and the middle sealing plate, and the outer dimensions of the connecting plate, the upper flange plate and the middle sealing plate are larger than the thick rubber block, so as to prevent the thick rubber block from being sheared and damaged by the connecting plate. The upper flange plate, the thick rubber block and the connecting plate are combined to reduce the vertical stiffness, vertical earthquake and vertical vibration of the bearing. The upper flange plate and the middle sealing plate are combined by steel hoop, steel ring and steel hook, so that the connecting plate and the thick rubber block are connected between the upper flange plate and the middle sealing plate to prevent the thick rubber block from being sheared and pulled, and the bearing bears tensile stress, and the thin-layer laminated rubber bearing is connected to the lower end of the middle sealing plate. The present invention also discloses two processes, by pre-pressing the connecting plate and the thick rubber block to reduce the total height of the steel hoop, or only increasing the groove height of the middle sealing plate, both of which can reduce the displacement of the steel hook relative to the bottom of the middle sealing plate under the action of vertical load, and prevent the steel hoop from blocking the shear displacement of the lower thin-layer laminated rubber bearing, thereby achieving seismic isolation and vibration isolation.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figure 1-3A three-dimensional vibration dual-control rubber bearing includes an upper flange plate, a thick rubber block connecting plate 6, a middle sealing plate 7, a thin layer of laminated rubber 10, a thin steel plate 8, a rubber protective layer 13 and a lower flange plate 9, which are arranged in sequence from top to bottom. The connecting plate 6 and the thick rubber block 5 are stacked up and down between the upper flange plate 4 and the middle sealing plate 7. The outer dimensions of the connecting plate 6, the upper flange plate 4 and the middle sealing plate 7 are larger than the outer dimensions of the thick rubber block 5, which can effectively prevent the thick rubber block 5 from being sheared and damaged by the connecting plate. The upper flange plate 4 is fixed on the top of the uppermost thick rubber block 5. The upper flange plate 4 is combined with the thick rubber block 5 and the connecting plate 6, which can effectively reduce the vertical stiffness of the seismic isolation bearing and effectively reduce vertical earthquakes and vertical vibrations. The lower end of the middle sealing plate 7 is connected to the thin layer of laminated rubber 10. The middle of the thin layer of laminated rubber 10 is evenly distributed with multiple thin steel plates 8. The upper flange plate 4 and the middle sealing plate 7 are connected in sequence by a combination of steel hoop 1, steel ring 2 and steel hook 3, which can effectively prevent the thick rubber block from being damaged by shear and tension, and make the bearing bear tensile stress to achieve the effect of seismic isolation and vibration isolation.

[0037] Based on the above embodiment, the steel hoop 1 is fixed to the upper flange plate 4 by bolt connection or welding, the steel ring 2 and the steel hook 3 are fixed to the steel hoop 1 by bolt connection or welding, and the plurality of connecting plates 6 are fixed into a whole by bolt connection or welding. The upper end of the middle sealing plate 7 is fixed to the connecting plate 6 by bolt connection or welding. The bolt connection makes the overall structure easy to disassemble and maintain, and the welding connection makes the overall structure simple and reliable.

[0038] Based on the above embodiment, the steel hoop 1 can be arranged on the flange plate 4 as a whole or in N equal parts along the diameter direction, and the steel ring 2 and the steel hook 3 can be arranged on the steel hoop 1 as a whole or in N equal parts along the diameter or height direction. To facilitate processing, production and assembly, the inner diameter and outer diameter of the steel ring 2 are consistent with those of the steel hoop 1, the outer diameter of the steel hook 3 is consistent with the outer diameter of the steel hoop 1, and the inner diameter of the steel hook 3 is slightly smaller than the inner diameter of the steel hoop 1.

[0039] Based on the above embodiment, the lower flange plate 9 is fixedly arranged at the lower end of the thin layer of laminated rubber 10, and a boss is provided at the upper end of the lower flange plate 9. In order to facilitate the positioning of the connecting plate 6 and the thick layer of rubber block 5, a positioning process hole 12 is provided in the middle of the connecting plate 6, and connecting screw holes and welding grooves are provided on the circumference of the connecting plate 6. A groove is opened on the lower circumference of the middle sealing plate 7, and the steel hook 3 is overlapped at the lower end of the middle sealing plate 7 through the groove. Process holes 11 are provided in the middle and near the circumference of the thin steel plate 8.

[0040] The present invention also discloses an assembly process for a three-dimensional vibration dual-control rubber bearing, comprising the following steps:

[0041] S1: Assemble the middle sealing plate 7, the thin layer laminated rubber 10, the thin layer steel plate 8, the rubber protective layer 13 and the lower flange plate 9 into a thin layer rubber bearing through a vulcanization process;

[0042] S2: Place the steel hoop 1 through the thin rubber support and place it on the upper end of the lower flange plate 9;

[0043] S3: Connect the connecting plate 6, the thick rubber block 5, and the upper flange plate 4 to the upper end of the middle sealing plate 7 in sequence;

[0044] S4: Fix the lower end of the upper flange plate 4 by bolting or welding the steel hoop 1;

[0045] S5: Use a non-pre-stressing process to directly fix the steel ring 2 and steel hook 3 to the steel hoop 1 by bolts or welding; or use a pre-stressing process to first compress the connecting plate 6 and the thick rubber block 5 downward by a certain displacement, and then fix the steel ring 2 and steel hook 3 to the steel hoop 1 by bolts or welding, and place the steel hook 3 in the groove at the lower end of the middle sealing plate, thereby completing the installation of the overall three-dimensional vibration dual-control rubber bearing.

[0046] The above-mentioned pre-stressing process is used for assembly, which can reduce the total height of the steel hoop. The above-mentioned non-pre-stressing process is simpler and more convenient to assemble, but the height of the middle sealing plate groove must be increased. Both processes can reduce the displacement of the steel hook relative to the bottom of the middle sealing plate under the action of vertical load, effectively preventing the steel hoop from blocking the shear displacement of the lower thin-layer laminated rubber bearing, thereby achieving the effect of seismic isolation and vibration isolation.

[0047] The above detailed description is a specific description of one feasible embodiment of the present invention. However, the embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not depart from the technical spirit of the present invention should be included in the patent scope of this case.
