Three-dimensional vibration isolation support with built-in pre-pressing spring and thick-layer rubber
The invention relates to the field of earthquake, vibration and noise control, and discloses a three-dimensional vibration isolation support with built-in pre-pressing springs and thick-layer rubber, the three-dimensional vibration isolation support comprises an upper connecting plate and a lower connecting plate, and the upper connecting plate and the lower connecting plate are connected through the pre-pressing springs; an upper sealing plate is arranged at the bottom of the upper connecting plate; a lower sealing plate is arranged at the top of the lower connecting plate; and a deformation device is arranged between the upper sealing plate and the lower sealing plate. By increasing the thickness of the rubber layer, the vertical rigidity of the support is reduced, so that the purpose of vertical shock absorption is achieved, meanwhile, the pre-pressing spring is arranged to complement the bearing capacity, reduced due to increase of the thickness of rubber, of the thick rubber support, namely, the pre-pressing spring and the thick rubber support are cooperatively used for bearing, the tension generated by the pre-pressing spring is balanced by the steel wire rope, and the damping effect is improved. The device is suitable for shock isolation of building structures and shock isolation and vibration reduction of subway periphery and front upper cover structures under the action of earthquakes, so that the device has horizontal and vertical shock (vibration) isolation functions at the same time, and the tension condition meets related standard requirements.
本发明涉及地震和振动及噪声控制领域，公开了一种内置预压弹簧‑厚层橡胶的三维隔振支座，其包括上连接板和下连接板，所述上连接板和所述下连接板之间通过预压弹簧连接；所述上连接板底部设置有上封板；所述下连接板顶部设置有下封板；所述上封板与下封板之间设置有变形装置。本发明通过增加橡胶层的厚度，使支座竖向刚度减小，从而达到竖向减震(振)的目的，同时设置预压弹簧补足厚肉支座因橡胶厚度增加而下降的承载力，即预压弹簧和厚肉橡胶支座协同承载，由钢丝索平衡预压弹簧所产生的张力，适用于地震作用下建筑结构的隔震和地铁周边及正上盖结构的隔振减振，从而同时具备水平和竖向隔震(振)功能且受拉情况满足相关规范要求。
