Vibration double-control friction pendulum isolation bearing and assembly method thereof
The invention relates to a vibration double-control friction pendulum vibration isolation support and an assembly method thereof, and belongs to the technical field of vibration isolation and vibration reduction. Comprising an upper seat plate, a lower seat plate and a spherical crown body between the upper seat plate and the lower seat plate, and the spherical crown body comprises an outer spiral spring, an inner spiral spring, an upper spherical crown body and a lower spherical crown body and can comprise or does not comprise a damper; the centers of the inner spiral spring and the outer spiral spring are sleeved together to form a spiral spring unit; spring positioning rings are arranged on the lower portion of the upper spherical crown body and the upper portion of the lower spherical crown body, the upper end and the lower end of the inner spiral spring are positioned between the spring positioning rings of the upper spherical crown body and the lower spherical crown body respectively, and the outer spiral spring in the spiral spring unit is arranged on the peripheries of the inner spiral spring and the spring positioning rings in a sleeving mode; the damper comprises a damper spring, a fixed sleeve and a movable sleeve, wherein the fixed sleeve and the movable sleeve are inserted into each other, and damping media are injected into the fixed sleeve and the movable sleeve. The vertical vibration reduction effect is obvious, the vibration reduction efficiency is high, and the problems of vibration reduction and noise reduction of buildings on the subway can be effectively solved.
本发明涉及一种振震双控摩擦摆隔震支座及其装配方法，属于隔减震/振技术领域。包括上座板、下座板以及二者之间的球冠体，球冠体包括外螺旋弹簧、内螺旋弹簧、上球冠体、下球冠体，并可包括或不包括阻尼器；内螺旋弹簧与外螺旋弹簧中心套设在一起，从而构成一个螺旋弹簧单元；在上球冠体的下部以及下球冠体的上部均设有弹簧定位环，内螺旋弹簧上、下端分别定位在上球冠体及下球冠体的弹簧定位环之间，螺旋弹簧单元内的外螺旋弹簧套设在内螺旋弹簧以及弹簧定位环外周；阻尼器包括阻尼器弹簧以及相互插入的定套筒和动套筒，且定套筒与动套筒中还注入有阻尼介质。本发明竖向减振效果明显、减振效率高，能有效解决地铁上建筑的减振与降噪问题。
