Expansion structure and bridge inhaul cable
The invention provides an expansion structure and a bridge inhaul cable. The expansion structure comprises a first anchorage device and a steel strand, the first anchorage device is used for anchoring a composite material strand, one end of the steel strand is fixedly connected with the first anchorage device, and the other end of the steel strand is used for being connected with a bridge. When the bridge inhaul cable is tensioned, an expansion structure is arranged at the tail end of the composite material stranded wire, the composite material stranded wire is anchored on the first anchorage device, and then the steel stranded wire is fixedly connected with the first anchorage device. At the moment, a construction side can directly clamp and fix the steel strand by utilizing tensioning equipment, and then the composite material strand is pulled through the steel strand and the first anchorage device, so that tensioning of the composite material strand is completed. Similarly, when the bridge inhaul cable is fixed to the bridge floor, an expansion structure is arranged at the tail end of the composite stranded wire, so that the composite stranded wire is indirectly connected with the bridge floor through the steel stranded wire, the bridge inhaul cable located near the bridge floor is made of the steel stranded wire, and good anti-collision and fireproof performance is achieved.
本发明提供一种扩展结构及桥梁拉索，扩展结构包括第一锚具和钢绞线，第一锚具用于锚固复合材料绞线，钢绞线的一端与第一锚具固定连接，钢绞线的另一端用于与桥梁相连。张拉桥梁拉索时，在复合材料绞线的末端设置扩展结构，先使复合材料绞线锚固在第一锚具上，然后将钢绞线与第一锚具固定连接。此时，施工方可以利用张拉设备直接将钢绞线夹持固定，然后通过钢绞线和第一锚具来牵引复合材料绞线，完成对复合材料绞线的张拉。同样地，将桥梁拉索与桥面固定时，在复合材料绞线的末端设置扩展结构，使复合材料绞线通过钢绞线与桥面间接连接，处于桥面附近的桥梁拉索为钢绞线材质，具有很好的防撞和防火性能。
