Deformation-releasable shock insulation support and construction method thereof
The invention discloses a deformation-releasable shock insulation support and construction method thereof. The seismic isolation support comprises a seismic isolation cushion layer, the upper surface and the lower surface of the seismic isolation cushion layer are connected to flange plates in an attached mode, holes are formed in the flange plates, anchor bars for being connected with a foundation platform are arranged in the flange plates in a penetrating mode, and a steel cushion plate is pre-buried in the portion, on the upper surface of the seismic isolation cushion layer, of the foundation platform. And the contact surfaces of the steel base plate and the flange plates are subjected to roughening treatment. In the normal use stage, the bearing capacity of the support can be guaranteed through friction shearing resistance and tensile resistance of the anchor bars and the rigid cushion blocks, and other reinforcing measures do not need to be added. And in the support deformation release stage, a jack temporarily bears a vertical load, the seismic isolation cushion layer can automatically reset, excessive deformation of the shock insulation support is fully released, and the requirement of temperature deformation of an ultra-long concrete structure for the deformation capacity of the shock insulation support can be met.
本发明公开了一种变形可释放隔震支座及其施工方法，隔震支座包括隔震垫层，所述隔震垫层的上下表面分别贴合连接于法兰板，所述法兰板上开孔并穿设有供连接基础承台的锚筋，所述隔震垫层上表面的基础承台预埋有钢垫板，所述钢垫板与所述法兰板的接触面做粗糙处理。正常使用阶段通过摩擦抗剪、锚筋和刚性垫块抗拉，可保证支座承载力，无需附加其他加固措施。支座变形释放阶段，通过千斤顶临时承受竖向荷载，隔震垫层可自行复位，充分释放隔震支座的过大变形，能够满足超长混凝土结构温度变形对隔震支座变形能力的需求。
