Large-span continuous steel structure bridge prestress device
The invention relates to the field of bridge engineering construction devices, in particular to a large-span continuous steel structure bridge prestress device which comprises two clamping discs, clamping grooves used for clamping inhaul cables are formed in the opposite sides of the two clamping discs respectively and connected, a mounting groove with an opening in one side is formed in a bridge, rotating shafts are coaxially arranged on the opposite sides of the two clamping discs, and the rotating shafts are arranged in the mounting groove. A supporting rod is arranged on the bottom wall of the mounting groove, one rotating shaft is rotationally arranged in the side wall of the mounting groove in a penetrating mode, the other rotating shaft is rotationally arranged on the supporting rod in a penetrating mode, and a pulling disc assembly used for pulling the clamping disc to rotate so that the inhaul cable can be tensioned and a locking assembly used for locking the tensioned clamping disc are arranged in the mounting groove. The clamping grooves are symmetrical about the axis of the clamping disc and are arranged in an S shape, and the positions, opposite to the two ends of the clamping grooves, of the inhaul cables are tangent to the circumferential outer side wall of the clamping disc. The device has the advantage that the external prestress can be conveniently regulated and controlled.
本申请涉及桥梁工程施工装置领域，尤其是涉及一种大跨径连续钢构桥梁预应力装置，包括两个夹持盘，两个夹持盘的相对侧分别开有用于夹持拉索的夹持槽且连接，桥梁内开有一侧敞口的安装槽，两个夹持盘的相背侧均同轴设置有转轴，安装槽的底壁上设置有撑杆，一个转轴转动穿设在安装槽的侧壁内，另一个转轴转动穿设在撑杆上，安装槽内设置有用于拉动夹持盘转动使得拉索张紧的拉盘组件、用于对张紧后的夹持盘实现锁紧的锁紧组件；夹持槽关于夹持盘的轴线对称且呈S型设置，拉索相对夹持槽两端的位置与夹持盘的圆周外侧壁相切。本申请具有方便对体外预应力进行调控的优点。
