Anchoring structure of self-anchored suspension bridge
The invention relates to an anchoring structure of a self-anchored suspension bridge. The anchoring structure comprises a stiffening beam with a preformed hole, a fixing device, a cast steel anchor, a main cable and a high-strength steel pull rod. The fixing device is located on the inner side of a preformed hole of the stiffening beam, and the cast steel anchor is located at the bottom of the outer end of the stiffening beam. One end of the high-strength steel pull rod penetrates through a preformed hole of the stiffening beam and is fixed on the cast steel anchor, and the other end penetrates through the fixing device and is connected with the main cable through a nut. According to the invention, the situation that the flexible main cable strand penetrates through the stiffening beam is avoided, the stiffening beam partition plate does not need to be provided with too large holes, and the problem that in the construction process, the flexible cable strand is prone to colliding with the stiffening beam due to downward deflection is solved. The main cable strand anchoring ends are installed outside the stiffening beams, and compared with an existing traditional self-anchored suspension bridge main cable anchoring mode, the self-anchored suspension bridge main cable anchoring method has the advantages that construction is convenient, and the construction progress is accelerated.
本发明涉及一种自锚式悬索桥的锚固结构，所述锚固结构包括具有预留孔的加劲梁、固定装置、铸钢锚锭、主缆和高强钢拉杆；固定装置位于加劲梁预留孔的内侧，铸钢锚锭位于加劲梁外端的底部；高强钢拉杆一端穿过加劲梁预留孔固定于铸钢锚锭，另一端穿过固定装置通过螺母与主缆连接。本发明避免了在加劲梁内穿柔性主缆索股，加劲梁隔板无需开孔过大，并且避免了施工过程中柔性索股下挠与加劲梁容易产生冲突的问题。在加劲梁外安装主缆索股锚固端，与现有传统自锚式悬索桥主缆锚固方式相比，具有施工方便性，加快了施工进度。
