Soft steel energy dissipation inhaul cable limiting device
The invention relates to a limiting device capable of effectively limiting multi-directional displacement response of a bridge structure under the action of an earthquake and yielding and dissipating energy through soft steel, in particular to a soft steel energy dissipation inhaul cable limiter which comprises an upper embedded steel plate, a lower embedded steel plate, an upper connector, a hard steel base, a soft steel rod, an inhaul cable, a cable clamp, an upper anchor bolt, a lower anchor bolt and the like. According to the arrangement of the novel limiting device, the inhaul cable penetrates through a soft steel bar, the two ends of the inhaul cable are fixed through cable clamps, the soft steel bar penetrates through a bottom hole of a hard steel base, the hard steel base is fixed to a lower embedded steel plate through a lower anchoring bolt, the inhaul cable penetrates through a cable hole of an upper connector, and the upper connector is fixed to an upper embedded steel plate through an upper anchoring bolt. On the premise that longitudinal displacement of a bridge in a normal working state is met, the relative displacement between the upper embedded steel plate and the lower embedded steel plate is controlled within a controllable range through the inhaul cables, beam falling is prevented, and earthquake energy is effectively consumed through yield energy dissipation of the soft steel bars. The size is accurate, and assembly, disassembly and replacement are easy.
本发明涉及一种可有效限制桥梁结构在地震作用下多方向位移响应并通过软钢屈服耗能的限位装置——软钢耗能拉索限位器，包括上、下预埋钢板、上连接器、硬钢基座、软钢棒、拉索、索夹、及上、下锚固螺栓等几部分组成，该新型限位装置的布置如下：拉索穿过软钢棒并在两端用索夹固定，软钢棒穿过硬钢基座底孔，硬钢基座通过下锚固锚栓固定于下预埋钢板上，拉索穿过上连接器索孔，上连接器通过上锚固螺栓固定于上预埋钢板。本发明能够在满足正常工作状态桥梁纵向位移的前提下，利用拉索将上下预埋钢板之间的相对位移在一个可控的范围之内，防止发生落梁，并通过软钢棒屈服耗能有效消耗地震能量。尺寸精确，易于组装、拆卸及更换。
