Vertical vibration damping device for vibration isolation buildings
A vertical vibration damping device for vibration isolation buildings is provided with a stainless steel top plate with a contact surface subjected to mirror surface treatment, and the top plate is fixed on an upper buttress through a connecting sleeve and an upper anchoring bolt; a viscoelastic damper device is arranged and comprises an outer steel cylinder and an inner steel cylinder, an inner sleeve is coaxially and fixedly connected inside the outer steel cylinder, the inner steel cylinder is inserted between the outer steel cylinder and the inner sleeve, and a viscoelastic material interlayer is bonded between the inner surface of the inner steel cylinder and the outer surface of the inner sleeve; and cylindrical helical springs are coaxially arranged between the outer side of the inner steel cylinder and the inner side of the outer steel cylinder, the upper bottom surfaces of the springs are propped against the upper bottom surface of the outer steel cylinder, and the lower bottom surfaces of the springs are propped against the lower bottom plate of the inner steel cylinder. According to the vertical vibration damping device for vibration isolation buildings, the deformationof the horizontal plane of a structure is not influenced, the influence of vibration and secondary noise of subway operation on a building can be effectively reduced, and the comfort level of personnel in the building and the safety of instruments and equipment are guaranteed. The vibration damping function is played, and in order to adapt to the high-frequency vertical vibration caused by subwayoperation, the parallel-connected steel cylindrical helical springs can improve the reset speed of the viscoelastic damper.
一种隔振建筑用的竖向减振装置，有一接触面经镜面处理的不锈钢顶板，顶板利用连接套筒和上锚固螺栓固定在上支墩上；有一粘弹性阻尼器装置，包括外钢圆筒和内钢圆筒，外钢圆筒内同轴固连内套，内钢圆筒插在外钢圆筒和内套之间，内钢圆筒内表面与内套外表面之间粘连有粘弹性材料夹层；内钢圆筒外侧与外钢圆筒内侧之间同轴设置圆柱螺旋弹簧，弹簧上底面顶在外钢圆筒上底面，弹簧下底面顶在内钢圆筒的下底板上。本申请不影响结构水平面内变形，可有效减少地铁运行对建筑物的振动及二次噪声影响，保证建筑物内人员的舒适度及仪器设备的安全性；发挥减振作用，并联的钢制圆柱螺旋弹簧能提高粘弹性阻尼器复位速度，以适应因地铁运行引起的高频竖向振动。
