Description

Technical Field

[0001] The present invention relates to a seismic isolation support, and more particularly to a three-dimensional high-damping seismic isolation support with adjustable seismic isolation. Background Art

[0002] Isolation bearings are currently a very widely used base structure. Most of the existing isolation bearing structures adopt a laminated rubber structure, which achieves lateral shock absorption by stacking rubber and steel plates in sequence, and then uses the flexibility of the upper and lower rubbers to achieve vertical shock absorption. However, due to the staggered stacking of a layer of rubber and a layer of steel plate, the vertical shock absorption effect of the existing isolation bearings is not very good.

[0003] Moreover, in actual use, the vibration direction that the seismic isolation bearing bears is not unique. It often bears vibrations in multiple directions at the same time. At this time, the seismic isolation bearing will produce corresponding deformation due to the vibration. When the vertical vibration is strong and the lateral vibration is not strong, the seismic isolation bearing is best to mainly perform vertical seismic isolation. However, due to the effect of lateral vibration, the rubber of the seismic isolation bearing will be offset to the left and right, which will greatly affect the vertical shock absorption function of the bearing.

The upper flange plate 1 is fixed to the upper end of the laminated rubber 2, and the lower flange plate 3 is fixed to the lower end of the laminated rubber 2. A high-damping rubber pad 4 is fixed to the upper end of the laminated rubber 2, and the high-damping rubber pad 4 is arranged between the upper flange plate 1 and the laminated rubber 2. A steel hoop 5 is coaxially fixed to the lower side of the upper flange plate 1. The steel hoop 5 is connected to the high-damping rubber pad 4 through a connecting adjustment mechanism 6.

At the same time, the addition of the high-damping rubber pad 4 can effectively utilize the characteristics of the high-damping rubber to increase the vertical shock absorption function of the seismic isolation bearing. Then, through the setting of the connection adjustment mechanism 6, it is possible to effectively adjust the connection method between the steel sleeve 5 and the high-damping rubber pad 4, thereby changing whether the lateral deformation of the high-damping rubber pad 4 is restricted, thereby changing the main isolation direction of the seismic isolation bearing.

[0015] As an improved specific embodiment, the connection adjustment mechanism 6 includes an outer ring seat 61, an inner ring seat 62, a plug ring 63 and a vibration detection device 64.

The inner ring seat 62 is coaxially sleeved on the high damping rubber pad 4. The plug ring 63 is liftably arranged between the outer ring seat 61 and the inner ring seat 62. The vibration detection device 64 is fixed on the upper end face of the lower flange plate 3 and It is linked with the plug ring 63 to drive the plug ring 63 to move up and down, wherein the outer ring seat 61 is integrally arranged with the steel hoop 5, and the inner ring seat 62 is integrally arranged with the high-damping rubber pad 4.

Through the setting of the above structure, the upper flange plate 1 can be effectively kept in a horizontal state, thereby avoiding the problem of tilting of the entire seismic isolation bearing due to uneven gravity.

[0018] As an improved specific embodiment, one of the synchronous columns 7 in a group is a left column and the other is a right column. The left column includes a left bottom column 71 and a left sliding column 72. The upper end of the left sliding column 72 is fixed to the lower end surface of the upper flange plate 1, and the lower end can slide into the left bottom column 71, and a left piston 73 is coaxially fixed on the end. The left piston 73 divides the internal space of the left bottom column 71 into an upper space and a lower space, and the lower space is filled with a buffer solution. The lower end of the left bottom column 71 is fixed to the upper end surface of the lower flange plate 3, and the upper end of the left bottom column 71 is coaxially fixed with a left sealing cover 74. The left sliding column 72 passes through the center of the left sealing cover 74, and the right column includes a right bottom column 75 and a right sliding column 76.
