Prefabricated base-isolation stair structure
The invention discloses a prefabricated base-isolation stair structure which comprises a first ladder beam, a second ladder beam and prefabricated stairs between the first ladder beam and the second ladder beam; support pieces stretching out towards the prefabricated stairs are pre-embedded in an upper ladder beam and the second ladder beam; the prefabricated stairs are provided with upper ladderends and second ladder ends; the upper ladder ends and second ladder ends are erected on corresponding support pieces; first ladder ends and the corresponding support pieces are fixedly connected through a first base-isolation structure; the second ladder ends are detachably connected with the corresponding support pieces through a second base-isolation structure; and the prefabricated stairs canbe close to or far away from the support pieces on the second ladder beam in a limited manner under the action of external force. When a building encounters the action of an earthquake, the two base-isolation structures can reduce the action of the vertical force of the earthquake to reduce damage to the stair structure; and the second base-isolation structure of a sliding end enables the prefabricated stairs to slide left and right in a limited manner under the action of the earthquake, so that energy accumulation under the action of the horizontal force of the earthquake is reduced to reducedamage of the earthquake force to nodes.
本发明公开了一种装配式隔震楼梯结构，包括第一梯梁、第二梯梁，以及设于第一梯梁和第二梯梁之间的预制楼梯；上、第二梯梁中均预埋有朝向预制楼梯伸出的支撑件，预制楼梯具有上、第二梯端，上、第二梯端分别搭设于相应的支撑件上，第一梯端与相应的支撑件通过第一隔震结构固连，第二梯端与相应的支撑件通过第二隔震结构可拆卸连接，且预制楼梯可在外力作用下有限靠近或远离第二梯梁上的支撑件。在建筑物遭遇地震作用时，两个隔震结构可消减地震竖向力作用，减小楼梯结构破坏。滑动端的第二隔震结构可在地震作用下使预制楼梯进行左右限位滑动，从而消减地震水平力作用下的能量聚集，减小地震力对节点的破坏。
