Compression-shear deformation self-limiting vibration isolation device with adjustable vertical rigidity
The invention discloses a compression-shear deformation self-limiting vibration isolation device with adjustable vertical rigidity, and belongs to the technical field of building vertical vibration isolation. The problems that an existing vibration isolation device is not ideal in vertical vibration isolation effect, rigidity cannot be adjusted, the vertical bearing capacity is low, safety is poor, and machining difficulty is large are solved. The technical scheme includes that the upper steel member is provided with a middle concave structure, the lower steel member is provided with a middle convex structure, the upper steel member and the lower steel member are vertically and coaxially arranged to form an upper nested prismatic table and a lower nested prismatic table, inclined angles of inclined steel plates on four sides of the prismatic tables are identical, and rubber vibration isolation blocks are arranged between the inclined steel plates of the upper prismatic table and the lower prismatic table. The rubber vibration isolation blocks are placed between the inclined steel plates on the side faces of the upper prismatic table and the lower prismatic table to be combined into the vibration isolation device with low vertical rigidity, when the device bears vertical pressure, the rubber vibration isolation blocks generate compression-shear deformation, under the constraint of the inclined steel plates on the four faces of the upper prismatic table and the lower prismatic table, shear force between the inclined steel plates of the rubber vibration isolation blocks is converted into axial pressure, and the vibration isolation device is formed. The axial force is rapidly increased, and the self-limiting function of the device is achieved.
一种竖向刚度可调的压剪变形自限位隔振装置，属于建筑竖向隔振技术领域。解决目前隔振装置竖向隔振效果不理想、刚度无法调整、竖向承载力低、安全性差以及加工难度大的问题。技术要点：上部钢构件具有中部内凹结构体，下部钢构件具有中部外凸结构体，上、下部钢构件竖向同轴布置，形成上、下嵌套棱台，棱台四面斜向钢板倾斜角度相同，上、下棱台的斜向钢板之间设置橡胶隔振块。本发明将橡胶隔振块，放置于上、下棱台侧面的斜向钢板间，组合成具有较低竖向刚度的隔振装置，装置承受竖向压力时，橡胶隔振块产生压剪变形，在上、下棱台四面斜向钢板的约束下，橡胶隔振块斜向钢板方问的剪力转化为轴向压力，轴向力快速增加，实现装置的自限位功能。
