High-damping sliding energy dissipation limiting simple bridge seismic resistance check block device
The invention relates to the technical field of bridge seismic resistance, in particular to a high-damping sliding energy dissipation limiting simple bridge seismic resistance check block device whichcomprises an arc-shaped check block, a Y-shaped iron rod, a connecting rod and a sliding rod, the arc-shaped check block is of an arc-shaped hollow structure, and the bottom of the arc-shaped check block is fixed to the top of a pier; the front side wall and the rear side wall of the sliding rod are arc-shaped limiting plates protruding in the direction away from a main beam, an inner cavity of the sliding rod is filled with a high-damping energy dissipation buffering cushion, a sliding cavity used for allowing one end of the sliding rod to slide is formed in the high-damping energy dissipation buffering cushion in the vertical direction, and the other end of the sliding rod is connected with the Y-shaped iron rod through a connecting rod; and the top end of the Y-shaped iron rod is hinged with the side wall of the main beam. Multi-directional displacement of the main beam can be limited, kinetic energy of the main beam is converted into internal friction heat energy through the device, and therefore the effect of reducing damage is achieved.
本发明涉及桥梁抗震技术领域，尤其涉及一种高阻尼滑动耗能限位简便桥梁抗震挡块装置，包括弧形挡块、Y字型铁棒、连接杆以及滑动杆，所述弧形挡块呈弧形中空结构，其底部固定于桥墩的顶部，其前侧壁和后侧壁为向着远离主梁方向凸起的弧形限位板，其内腔中填充有高阻尼耗能缓冲垫，所述高阻尼耗能缓冲垫沿着竖直方向形成有用于所述滑动杆的一端滑动的滑腔，所述滑动杆的另一端与所述Y字型铁棒之间通过连接杆相连；所述Y字型铁棒的顶端与所述主梁的侧壁铰接。本发明能够限制主梁的多向位移，该装置将主梁的动能转化为内部的摩擦热能，从而达到减少破坏的作用。
