Anti-drawing vertical seismic isolation device adopting compression-shear type laminated rubber
The invention discloses an anti-drawing vertical seismic isolation device adopting compression-shear type laminated rubber, a main body of the anti-drawing vertical seismic isolation device is located between a bottom plate and a top plate, an anti-drawing key is installed on the bottom plate through a connecting bolt, a four-edge ring plate is arranged at the bottom of the top plate, and a plurality of anti-drawing keys are arranged on the top plate. The lower portion of the four-edge annular plate is arranged in an inner cavity formed by the anti-pulling keys, a pressure-bearing prismatic table is arranged in the cavity of the four-edge annular plate, and a laminated rubber module is arranged between the pressure-bearing prismatic table and the four-edge annular plate. The vertical movement of the upper structure can be converted into the compression-shear deformation of the laminated rubber, so that the earthquake energy is effectively consumed, and the earthquake response of the structure is reduced.
本发明公开了一种采用压剪型叠层橡胶的抗拉拔竖向隔震装置，抗拉拔竖向隔震装置主体位于底板与顶板之间，所述抗拔键通过连接螺栓安装在底板上，所述顶板的底部设置有四棱环板，所述四棱环板的下部置于所述抗拔键构成的内腔中，所述四棱环板的空腔中设置承压棱台，所述承压棱台和四棱环板之间设置有叠层橡胶模块。本发明能够将上部结构的竖向运动转换为叠层橡胶的压剪变形，从而有效消耗地震能量，减小结构的地震响应。
