Three-direction shearing large-displacement three-dimensional seismic mitigation and isolation support
The invention discloses a three-direction shearing large-displacement three-dimensional seismic mitigation and isolation support, which belongs to the technical field of seismic mitigation and isolation, and comprises a base, a horizontal seismic mitigation and isolation device, a vertical seismic mitigation and isolation device, a stainless steel plate and a sliding layer, the inner wall of the bottom of the base is wrapped by a stainless steel plate to form a sliding friction face, and a sliding layer is pasted to a groove in the lower surface of the vertical shock absorption and isolation device. According to the three-way shearing large-displacement three-dimensional seismic mitigation and isolation support, the problems that an existing laminated rubber support and an existing friction pendulum support cannot well isolate vertical vibration and even can amplify the vertical vibration are solved, seismic mitigation and isolation are carried out through deformation of the high-damping rubber layers in the horizontal direction and the vertical direction, and the seismic mitigation and isolation effect is good. The shock absorption and isolation in the horizontal direction and the vertical direction are separately achieved through design, coupling of horizontal shock and vertical shock is avoided, raw materials and the structure are simple, stress is reasonable, the total height of the support is low, stability is good, and meanwhile the good anti-drawing capacity is achieved.
本发明公开了一种三向剪切大位移三维减隔震支座，属于减隔震技术领域，包括底座、水平向减隔震装置、竖向减隔震装置、不锈钢板和滑动层，底座内设置有水平向减隔震装置和竖向减隔震装置，底座底部的内壁被不锈钢板包覆而形成滑动摩擦面，竖向减隔震装置的下表面凹槽粘贴滑动层。本发明解决了现有叠层橡胶支座和摩擦摆支座并不能很好的隔绝竖向震动，甚至会放大竖向的震动的问题，本发明的三向剪切大位移三维减隔震支座，在水平和竖向均通过高阻尼橡胶层的变形进行减隔震，并通过设计分开实现了水平向与竖向的减隔震，避免了水平震动与竖向震动的耦合，其原材料和构造简单、受力合理、支座总高度底、稳定性好，同时具有良好的抗拉拔能力。
