Embodiment 1

[0030] see Figure 1 to Figure 5 , a separate three-dimensional damping and energy-dissipating seismic isolation bearing, including an upper structure 1, a middle bearing platform 2, a lower foundation bearing platform 3, a horizontal seismic isolation bearing 4, an upper friction plate 5, a lower friction plate 6, and a horizontal limit Block 7, connecting corner block 8, vertical shock-isolation support 9; the superstructure 1 is connected with the horizontal shock-isolation support 3 by bolts; the horizontal shock-isolation support 3 is fixed on the middle bearing platform 2; the middle bearing platform 2. It is fixedly connected with the upper friction plate 5; the upper friction plate 5 is in contact with the lower friction plate 6 and can slide freely; the connecting corner block 8 is a triangular prism, which is fixedly connected with the lower friction plate 6 and the vertical vibration isolation support respectively 9. The vertical shock-isolation support 9 is fixed o...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, and the special features are as follows: Image 6 As shown, three vertical shock-isolation supports 9 are used in this embodiment, and their horizontal positions are arranged symmetrically to the center to form a group of spatially symmetrical outwardly expanding cylindrical structures. The vertical vibration isolation bearing 9 adopts lead core rubber bearing, and every two vertical vibration isolation bearings 9 are in the shape of "eight" with the horizontal line, and are placed obliquely at the same angle, and the inclination angle is according to the vertical The vertical displacement required for the load and vibration isolation is calculated and determined, and adjusted between 0°-90°; when subjected to vertical pressure, the upper friction plate 5 and the lower friction plate 6 undergo a symmetrical outward expansion relative sliding, and the vertical isolation The shock bearing 9 undergoes compression-shear...

Abstract

The invention discloses a separation type damping energy consumption three-dimensional seismic isolation support which comprises a horizontal seismic isolation unit arranged between an upper structure and a middle bearing platform, and a vertical seismic isolation unit arranged between the middle bearing platform and a foundation bearing platform. The horizontal seismic isolation unit is a vertical lead rubber support which is axially and vertically installed, and the vertical seismic isolation unit is formed by connecting at least two inclined lead rubber supports equal in size specification in parallel to form a set of outward expanding cylindrical structure in space symmetry so that the vertical deformation borne by the vertical seismic isolation unit can be transformed into inclined deformation and outward expanding displacement of the inclined rubber supports. An upper friction plate and a lower friction plate are arranged between the vertical seismic isolation unit and the middle bearing platform, and initial supporting force is provided and seism / vibration energy is dissipated through friction sliding of a contact face. According to the separation type damping energy consumption three-dimensional seismic isolation support, seism and environment vibration in three directions can be isolated at the same time, the seism / vibration response and seism / vibration transmission of a protected structure or device with the separation type damping energy consumption three-dimensional seismic isolation support are effectively controlled, and the safety under the seism / vibration action is protected.

Description

technical field [0001] The invention relates to the technical field of environmental vibration and shock resistance and shock absorption, in particular to a separate three-dimensional shock-isolation bearing for damping and energy consumption, which can be used for shock / vibration reduction in ordinary buildings, special structures, bridges, and mechanical equipment. Background technique [0002] With the development of modern industry and the expansion of urban scale, environmental vibration and noise problems caused by many vibrations such as industrial equipment and rail transit have gradually emerged. Environmental vibration has become one of the seven major public hazards affecting human life and production. Environmental vibration has a serious impact on the physical and mental health of human beings, the comfort of living and the production of precision instruments. For example, subway vibration has an impact on the construction production around the line, the safety ...
