specific Embodiment 1

[0021] refer to figure 1 The lower connecting plate 10 of the laminated rubber bearing 1 is buckled in the basin-type steel bearing 7, and a polytetrafluoroethylene plate 4 is inlaid on the bottom upper surface of the basin-type steel bearing 7, and the polytetrafluoroethylene plate 4 is preferably round Shape, the lower surface of the lower connecting plate 10 of the laminated rubber bearing 1 is inlaid with a stainless steel plate. The stainless steel plate can be a circular mirror-finished stainless steel plate 3 . The inner flange 11 of the pot-type steel bearing 7 is used to limit the horizontal and vertical translation of the laminated rubber bearing 1 and the rotation around the vertical direction. The mirror surface mounted on the lower connecting plate 10 of the laminated rubber bearing 1 The stainless steel plate 3 and the polytetrafluoroethylene plate 4 inlaid on the upper surface of the bottom of the pot-type steel support 7 form a rotating contact surface. Since ...

specific Embodiment 2

[0022] refer to figure 2 , The specific embodiment 2 is similar in structure to the specific embodiment 1, the difference lies in the way the basin-type steel bearing 7 constrains the lower connecting plate 10 of the laminated rubber bearing 1 . In this example, a depression is provided on the lower connecting plate 10, and a tooth-shaped protrusion matched with the depression is provided on the basin-type steel support 7. The lower connecting plates 10 of the laminated rubber bearing 1 are connected in a toothed interlocking manner, constraining the horizontal and vertical translation and rotation around the vertical direction of the lower connecting plates 10 of the laminated rubber bearing 1 . There can be one set of tooth-shaped protrusions constituting the tooth-shaped interlocking structure, or multiple sets, and the number of the tooth-shaped protrusions is not limited. But to reduce friction, a set is preferred.

specific Embodiment 3

[0023] refer to image 3 , the three-dimensional shock-absorbing bearing mainly includes a laminated rubber bearing 1 and a basin-type steel bearing 7 . Among them, there are two pot-type steel bearings 7, an upper connecting plate 12 is arranged above the laminated rubber bearing 1, and a lower connecting plate 10 is arranged below, and the upper connecting plate 12 and the lower connecting plate 10 are connected with the basin-type steel bearing 7. matching. And the upper connecting plate 12 and the lower connecting plate 10 are respectively buckled and placed in the basin-type steel bearings 7 that they match, and the two basin-type steel bearings 7 are respectively used to restrain the upper connecting plate 12 and the lower connecting plate 1 of the laminated rubber bearing 1 The lower connecting plate 10 can only rotate around the vertical axis of the basin-type steel bearing 7 in the basin-type steel bearing 7 . The laminated rubber bearing 1 is fixedly connected with...

Abstract

The invention relates to a shock mount for a building. The three-dimensional shock mount comprises a laminated rubber support and a basin type support, wherein a lower connecting board is arranged under the laminated rubber support; the basin type support is matched with the lower connecting board; an inner flange used for limiting the movement condition of the lower connecting board is arranged on the basin type support; and the lower connecting board is buckled in a basin type chamber of the basin type support. The shock mount can release the horizontal deformation and the torsional deformation of a supported engineering structure, reduce the risks of damages caused by the deficiency of horizontal deformation capability and torsional deformation capability of a structural component and improve the shock resistant performance of the engineering structure.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a shock-absorbing support of a building. Background technique [0002] With the development of social economy and construction technology, there are more and more high-rise and super high-rise building structures. In order to meet the architectural aesthetic requirements, the proportion of these high-rise or super-high-rise structures with irregular planes or facades will increase, such as the new CCTV building, Guangzhou New TV Tower, and Guangdong Science Center built in my country in recent years. Scholars from various countries have conducted many theoretical and technical studies on how to improve the seismic safety of these irregular structures against the torsional component of ground motion and release the torsional deformation of these structures during daily use. [0003] Among them, seismic isolation technology, as a mature, reliable and effective technology...
