Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 , 2 , 3, and 4, the three-dimensional seismic isolation bearing of the present invention includes a lower connecting plate 1, a middle connecting plate 2, a horizontal seismic isolation bearing 3, an upper connecting plate 4, a disc spring 5, a viscous fluid damper piston 6, Viscous fluid 7, viscous fluid damper outer cylinder 8, guide rod 9, fixing bolt 10, limit bolt 11, guide sleeve 12, ring spring 13.

[0025] Such as figure 1 As shown, the middle connecting plate 2 is rigidly connected with the piston 6 of the viscous fluid damper, and the middle connecting plate 2 and the piston 6 of the viscous fluid damper can reciprocate simultaneously. There is an annular guide sleeve 12 on the inner side of the middle connecting plate 2, which can be sleeved with the outer cylinder 8 of the viscous fluid damper, and the out...

Abstract

The invention discloses a three-dimensional isolation support. The three-dimensional isolation support comprises a lower connecting plate (1), a horizontal isolation support body (3), an intermediate connecting plate (2), a disc spring vertical isolation device and an upper connecting plate (4) which are arranged from bottom to top in sequence. Vertical isolation is achieved through a viscous fluid damper, a disc spring set, multiple connecting plates, a guiding rod, a limiting bolt, an annular spring and other auxiliary devices, and the connecting plates, the guiding rod, the limiting bolt and the annular spring guarantee the normal conducting of vertical isolation. A traditional isolation support is improved due to the adoption of vertical isolation, vertical vibration and small vertical earthquakes can be resisted, and the structure has certain vertical vibration (earthquake) isolating ability.

Description

technical field [0001] The invention relates to the field of building structure foundations, in particular to a three-dimensional shock-isolation support, which is used for the anti-seismic design of multi-storey building structures with small mass and the vibration isolation application of equipment and instruments sensitive to vibration with small mass. Background technique [0002] Base isolation is a seismic isolation technology developed in recent years for the foundation of building structures. Its feature is to effectively isolate the horizontal earthquake action from the foundation to the superstructure, thereby reducing the horizontal vibration of the superstructure. The existing products are mainly ordinary rubber shock-isolation bearings, lead-core rubber shock-isolation bearings, high-damping rubber bearings, etc. All kinds of seismic isolation bearing products have been widely used in the seismic application of multi- and high-rise building structures. Although...
