Pre-tightening disc spring vibration isolation device
The invention discloses a pre-tightening type disc spring vibration isolation device, and belongs to the technical field of building vibration isolation. In a building structure construction state, an upper main body and a lower main body are connected through a pre-tightening steel bolt in the horizontal direction to realize a pre-tightening function, so that the vibration isolation device keeps vertical displacement unchanged, and the construction precision of an upper structure is ensured; in a normal working state, the upper structure is completely supported by the dish-shaped group, and the upper main body and the lower main body can perform independent relative movement by utilizing the advantages of low vertical rigidity and large bearing capacity of the dish-shaped group, so that the effect of isolating environmental vibration is achieved; under the earthquake working condition, the upper main body and the upper structure connected with the upper main body synchronously move, the lower main body and the lower structure connected with the lower main body synchronously move, the upper main body and the lower main body generate relative displacement, when the vertical stretching displacement of the vibration isolation device exceeds the designed displacement, gaps between the suspension type stretching springs arranged on the periphery are eliminated, and tension is generated after contact; and the vibration isolation device is prevented from excessively stretching and displacing.
本发明公开了一种预紧式碟簧隔振装置，属于建筑物隔振技术领域，在建筑结构施工状态下，上主体和下主体通过设置水平方向的预紧钢栓连接上主体和下主体，实现预紧功能，使隔振装置保持竖向位移不变，保证上部结构施工精度；正常工作状态下，上部结构完全由碟形组支撑，利用其竖向刚度低，承载力大的优势，上主体和下主体之间可发生独立的相对运动，达到隔离环境振动的效果；在地震工况下，上主体和与之相连的上部结构同步运动，下主体和与之相连的下部结构同步运动，两者产生相对位移，当隔振装置的竖向拉伸位移超过设计位移时，设置在周边的悬挂式拉伸弹簧之间的间隙消除，接触后产生拉力，防止隔振装置拉伸位移过大。
