Additional disc spring type anti-pulling friction pendulum vibration isolation support and connecting method
The invention relates to an additional disc spring type anti-pulling friction pendulum vibration isolation support and a connecting method, and belongs to the technical field of seismic mitigation and isolation. A friction pendulum unit is composed of an upper cover plate support with a guide rod hole, a sliding block, a polyfluortetraethylene plate and a lower cover plate support with a bolt hole; the guide rod is divided into a rod cap and a round rod; the disc spring combination pair is formed by combining a plurality of disc springs in an overlapping and involution mode. When an earthquake occurs, the sliding block slides along the sliding surface to generate friction force to consume energy; the disc spring vertically stretches out and draws back along the guide rod to absorb vibration and generate elastic force, part of earthquake energy in the horizontal direction is vertically absorbed, and the horizontal design displacement of the friction pendulum is shortened. The guide rod and the anti-pulling plate generate horizontal friction force to consume energy; at any sliding position, the bearing reaction force generated by the anti-pulling plate plays an anti-pulling role. The energy dissipation capacity, the pulling resistance and the self-resetting capacity of the friction pendulum can be changed by designing the rigidity, the friction coefficient and the like of the disc spring combination pair, the soft limiting capacity of the sliding block is achieved, and collision between the sliding block and the limiting stopper is avoided.
一种附加碟簧式抗拔摩擦摆隔振支座及连接方法，属于减隔震技术领域，摩擦摆单元由带导杆孔的上盖板支座、滑块、聚四氟乙烯板、带螺栓孔的下盖板支座构成；导杆划分为杆帽和圆杆两部分；碟簧组合对由多个碟簧通过叠合和对合组合而成。当发生地震时，滑块沿滑动面滑动产生摩擦力来耗能；碟簧沿导杆竖向伸缩来吸振并产生弹力，实现了在竖向吸收部分水平向的地震能量，缩短了摩擦摆的水平设计位移；导杆与抗拔板产生水平向摩擦力来耗能；在任一滑动位置，抗拔板产生的支反力起到了抗拔的作用。可以通过设计碟簧组合对的刚度和摩擦系数等来改变摩擦摆的耗能能力、抗拔能力、自复位能力，并实现了滑块的软限位能力，避免了滑块与限位器的撞击。
