Embodiment Construction

[0031] The present invention will be further explained below in conjunction with examples and the drawings of the specification.

[0032] The present invention is an anti-pull three-dimensional rubber friction pendulum shock isolation support, which is composed of two pairs of concave discs 1, one rubber interlayer pad 2, two friction sheets 3, a first cable 6, a second cable 7 and 2 It is composed of vertical disc spring discs. The two pairs of concave disks 1 are symmetrically stacked on the rubber interlayer pad 2. The two ends of the rubber interlayer pad 2 are bonded with friction sheets 3 on the convex surfaces. The vertical disc spring 4 and the vibration isolation disk 5 form a vertical vibration isolation disk. The vertical vibration isolation disk is connected to the concave disk 1 through the vertical disk spring 4, and the limit ring 8 is connected to the vibration isolation disk 5. The two pairs of limit rings 8 and the two pairs of concave disk 1 respectively pass t...

Abstract

The invention discloses an anti-pulling three-dimensional rubber friction-pendulum earthquake-isolation support. The anti-pulling three-dimensional rubber friction-pendulum earthquake-isolation support comprises two concave-surface discs correspondingly arranged up and down, a rubber interlayer pad arranged between the two concave-surface discs and two earthquake-isolation discs arranged on the upper side of the concave-surface disc at the upper portion and arranged on the lower side of the concave-surface disc at the lower portion respectively; the upper side and the lower side, in contact with the two concave-surface discs, of the rubber interlayer pad are each provided with a friction slice, vertical belleville springs are connected between the concave-surface discs and the earthquake-isolation discs, first pulling cables are connected between the opposite inner sides of the two concave-surface discs, and second pulling cables are connected between the opposite inner sides of the two earthquake-isolation discs. The anti-pulling three-dimensional rubber friction-pendulum earthquake-isolation support is combined with the advantages of a rubber support and a friction-pendulum support, and the curvature of the rubber interlayer pad and the friction coefficient of a friction pendulum are designed respectively to achieve the advantages of multistage fortifying earthquake isolation; the pulling cables can provide vertical pull for improving the anti-pulling performance of the support, the vertical earthquake-isolation discs can isolate vertical earthquake motion to meet the three-dimensional earthquake-isolation requirement, and the anti-pulling three-dimensional rubber friction-pendulum earthquake-isolation support is more suitable for practical engineering and is convenient to apply and popularize.

Description

Technical field [0001] The invention is a pull-out-resistant three-dimensional rubber friction pendulum seismic isolation bearing, specifically a component suitable for seismic isolation and reinforcement of bridges and building structures. Background technique [0002] The traditional friction pendulum bearing achieves the shock isolation function through frictional energy consumption. In a traditional friction pendulum, although its period, lateral stiffness, damping, displacement capacity, etc. can all be determined independently. However, these parameters are constant values ​​under all levels of earthquake motion and displacement, which is not conducive to achieving flexible design and multiple performance goals under small, medium and large earthquakes. In order to solve this problem, multiple friction pendulum supports have been designed abroad. However, due to the complex structure of the multi-friction pendulum support, the mechanical performance stability needs t...
