Bridge tower cable saddle of cable-stayed bridge inhaul cable
The invention relates to a bridge tower cable saddle of cable-stayed bridge inhaul cable. The bridge tower cable saddle (3) is arranged on a bridge tower (2), used for fixing an upper end of a stay cable (1) and comprises a saddle (31), wherein connecting pieces (32) are arranged at two ends of the saddle (31) respectively, the connecting pieces (32) are hinged to the saddle and can deflect up anddown, the connecting pieces (32) need to be connected with an upper end of the stay cable, connecting holes (323) are formed in the connecting pieces (32), and are in threaded connection with an anchor head at an upper end of the stay cable (3). The bridge tower cable saddle is advantaged in that an anchoring cavity does not need to be formed in the bridge tower, and the bridge tower is compact and intensive in size, the connecting pieces directly connected with an end of the stay cable are hinged to the saddle, that is, the connecting pieces can be adjusted relative to an adaptive angle of the saddle according to stress, so the stay cable can adapt to deflection caused by construction angle deviation or external dynamic load at the bridge tower end, and the stress of a stay cable component is improved.
本发明涉及一种斜拉桥拉索的桥塔索鞍，所述桥塔索鞍(3)设置在桥塔(2)上，用于固定斜拉索(1)上端，包括鞍座(31)、鞍座(31)两端分别设置连接件(32)，所述连接件(32)与鞍座铰接可实现上下偏转，所述连接件(32)要与斜拉索上端连接。所述连接件(32)上开设有连接孔(323)，所述连接孔(323)与斜拉索上端的锚头螺接。本申请无需在桥塔内部设置锚固腔室，桥塔尺寸紧凑集约；与斜拉索端部直接连接的连接件与鞍座铰接，即连接件可根据受力相对鞍座适应性角度调节，让斜拉索在桥塔端可以适应施工角度偏差或外部动载荷引起的偏折，改善斜拉索构件的受力。
