Energy dissipation buffer type limitable bridge anti-seismic check block structure with steel spring
The invention belongs to the technical field of bridge earthquake resistance, and particularly relates to an energy dissipation buffer type limitable bridge anti-seismic check block structure with a steel spring. The structurecomprises a steel corbel and a check block structure, the steel corbel is fixed to the side face of the top of a pier near a movable support, and a check block body is fixedto the top of the steel corbel and comprises a steel plate, a steel spring, a hinge structure, a rolling shaft, a hinge fixing body and a four-round-hole limiting stopper. By means of the bridge anti-seismic check block structure, large displacement between the beam body and the bridge pier can be effectively limited, beam falling damage of the beam body in the bridge direction and the transversebridge direction and damage that the beam body is vertically separated from the support are prevented, damage to the movable support and the expansion joint is reduced, and seismic energy can be consumed by means of movement of the rolling shafts. The device is simple in structure and convenient to construct.
本发明属于桥梁抗震技术领域，具体涉及一种具有钢弹簧的耗能缓冲型可限位桥梁抗震挡块结构，包括钢牛腿和挡块结构，所述钢牛腿固定在活动支座附近的桥墩顶部的侧面，所述挡块块体固定在钢牛腿顶部，包括钢板、钢弹簧、合页结构、滚轴、合页固定体以及四圆孔限位器。本发明桥梁抗震挡块结构能有效限制梁体和桥墩之间的较大位移，防止梁体发生顺桥向和横桥向落梁危害以及梁体竖向脱离支座危害，减小活动支座和伸缩缝的损坏，还可以依靠滚轴的运动消耗地震能量。本装置构造简单，施工方便。
