Concrete-filled steel tube arch bridge cable replacing device
The invention discloses a concrete-filled steel tube arch bridge cable replacing device which is used for replacing a sling of a sling structure arch bridge and is characterized by comprising a saddleframe erected on an arch rib of the arch bridge, a bracket supported below a cross beam of the arch bridge and a temporary suspender used for connecting the saddle frame with the bracket, wherein thetemporary suspender tensions and supports the cross beam to replace the current sling to be stressed, and the cable replacing device is dismounted after the current sling is replaced. According to the device, in the cable replacing process and the secondary cable replacing process, the overall safety of the bridge arch beam can be guaranteed, vehicle passing is not affected, and the arch rib andthe main beam are clear in force transmission and reasonable in stress.
本发明公开了一种钢管混凝土拱桥换索装置，用于对吊索结构拱桥的吊索进行更换，其特征在于，该装置包括：用于架设在拱桥拱肋上的鞍架，用于托在拱桥横梁下的托架，以及用于连接鞍架与托架的临时吊杆；其中，该临时吊杆张紧并托起横梁以替代当前吊索受力，在完成当前吊索的更换后拆除换索装置。本发明装置在换索过程和二次换索过程中，能保证桥梁拱梁整体安全，不影响车辆通行，使拱肋和主梁传力明确，受力合理。
