Three-dimensional shock insulation support
The invention discloses a three-dimensional shock insulation support, and belongs to the field of earthquake prevention and disaster reduction of civil engineering. The three-dimensional shock insulation support comprises an upper connecting plate, a lower connecting plate, steel plate sliding grooves, laminated rubber, a link joint, a hinge bolt, a universal joint and a dog-bone-shaped SMA rod, wherein an upper layer steel plate is connected with a building superstructure through bolts, a lower layer steel plate is connected with a building foundation, a laminated rubber core is arranged between the upper and lower steel plates, the two ends of the SMA rod used for vertical shock insulation are hinged to an upper V-shaped rigid arm and a lower V-shaped rigid arm through connecting pieces, and the SMA rod is connected with the connecting pieces through threads. The other two ends of the two sets of V-shaped rigid arms are hinged to the sliding joint, embedded into the upper sliding groove and the lower sliding groove which are perpendicular to each other and slide in the sliding groove direction, the dog-bone-shaped SMA rod, the two sets of V-shaped rigid arms and the two sliding groove-rigid arm connecting pieces are nested together to be combined into an SMA frame used for vertical vibration isolation, and therefore on the basis of horizontal vibration isolation of an original SMA-LNR, the vertical seismic isolation performance of the structure is improved, and the loss to the building after an earthquake is reduced.
本发明公开了一种三维隔震支座，属于土木工程防震减灾领域；包括上连接板、下连接板、钢板滑槽、叠层橡胶、链接节点、铰接螺栓、万向节、狗骨型SMA棒。上层钢板与建筑上部结构通过螺栓相连，下层钢板与建筑物基础相连；叠层橡胶芯置于上下两层钢板中间位置；用于竖向隔震的SMA棒两端通过连接件与上下两组V字型刚臂铰接，SMA棒与连接件之间通过螺纹连接。两组V字型刚臂另外两端铰接在滑动节点上，并嵌入与相互垂直的上下两组滑槽当中，在滑槽方向上滑动，狗骨型SMA棒、两组V字型刚臂以及两个滑槽‑刚臂连接件嵌套在一起组合成用于竖向隔震的“SMA”架，从而达到在原有SMA‑LNR在水平向隔振的基础上，改善结构竖向的隔震性能，减少震后对建筑带来的损失。
