Abstract

The invention discloses a vertical variable-rigidity three-dimensional shock / vibration isolation device. The vertical variable-rigidity three-dimensional shock / vibration isolation device comprises an upper cover plate (1), a first rigidity element (2), a second rigidity element (3), an upper clamping plate (4), a lower clamping plate (5), a fastening bolt (6), a vertical guide device (7), a middle plate (8), a middle slide block (9), a lower baseplate (10) and a slide material (11), wherein the first rigidity element (2), the second rigidity element (3), the upper clamping plate (4), the lower clamping plate (5), the fastening bolt (6) and the vertical guide device (7) are arranged between the upper cover plate (1) and the middle plate (8); the middle slide block (9) is positioned between the lower baseplate (10) and the middle plate (8); a convex block is formed in the center of the lower surface of the middle plate; the lower end surface of the convex block is a concave curved surface; the upper end surface of the middle slide block is a convex curved surface matched with the concave curved surface; the lower end surface of the middle slide block is arranged on the upper surface of the lower baseplate; and the contact surface of the lower end surface of the middle slide block and the upper surface of the lower baseplate is filled with the slide material.

Description

technical field [0001] The invention relates to structural vibration isolation / vibration isolation technology, in particular to a three-dimensional vibration isolation / vibration isolation device with vertically variable stiffness. Background technique [0002] With the vigorous construction of rail transit, the vibration impact caused by rail transit operation on surrounding building structures has become increasingly prominent, and there is a greater demand for vertical isolation of rail traffic vibrations adjacent to subway structures. At the same time, the entire land area of ​​our country is fortified against earthquakes, and the seismic performance of the structure must also ensure that it meets the design requirements. [0003] Structural vibrations caused by rail transit operation are mainly high-frequency vertical vibrations; structural shaking caused by earthquakes are mostly horizontal low-frequency vibrations. How to better control the vibration caused by the ope...
