Multidirectional displacement limiting device
The invention provides a multidirectional displacement limiting device which comprises an upper disc and a lower disc, the upper disc comprises an upper disc cover and a limiting outer disc, the upper disc cover is fixedly connected with an upper building, and the limiting outer disc is arranged below the upper disc cover; the lower disc comprises a limiting inner disc and a lower disc bottom support, the limiting inner disc is arranged above the lower disc bottom support, the limiting inner disc and the limiting outer disc are mutually nested, a gap is formed between the limiting inner disc and the limiting outer disc, and the lower bottom support is connected with an external base. Through the combination of the upper disc and the lower disc, under accidental working conditions, before the relative deformation between an upper building and the base is about to exceed the allowable deformation of a vibration isolation device or other deformable supports connecting the upper building and the base, the structure plays a role in limiting protection, and normal work of the vibration isolation device or other deformable supports is guaranteed; meanwhile, it is guaranteed that the building above does not displace or overturn by a large margin. Under the normal use state of the vibration isolation device or other deformable supports, the upper disc and the lower disc move independently through the gap between the upper disc and the lower disc, and the limiting device is not triggered to work.
本发明提供了一种多向位移限制装置，包括上盘与下盘：上盘包括上盘盖和限位外盘，上盘盖与上方建筑物固定连接，限位外盘设置于上盘盖下方；下盘包括限位内盘和下盘底托，限位内盘设置于下盘底托上方，且限位内盘与限位外盘相互嵌套并具有间隙，且下方底托与外部的底座相连接。本发明通过上下盘之间的组合，实现了在偶然工况下，当上方建筑物与底座间的相对变形即将超过连接二者的隔振装置或其他可变形支座的允许形变之前，上述结构起到限位保护作用，保证隔振装置或其他可变性支座的正常工作，同时保证上方建筑物不出现过大幅度的位移或倾覆。在隔振装置或其他可变形支座的正常使用状态下通过上下盘之间的间隙使得上下盘之间相互独立运动，不触发限位装置工作。
