Front fulcrum guy cable hanging basket for cable-stayed bridge girder construction and installation method thereof
The invention provides a front fulcrum guy cable hanging basket for cable-stayed bridge girder construction and a mounting method thereof. The front fulcrum cable-stayed hanging basket for construction of the main beam of the cable-stayed bridge comprises a cross beam structure and two longitudinal beam structures. The two longitudinal beam structures are arranged on the two sides of the cable bent tower limb at intervals in the first direction. The cross beam structure is fixedly connected with the two longitudinal beam structures and comprises a front cross beam, a middle cross beam, a rear cross beam and two rear web members, the two ends of the front cross beam are connected to the connecting positions of the main beam hanging basket parts and the arc-shaped heads in the two longitudinal beam structures correspondingly, and the two ends of the middle cross beam are connected to the ends, away from the arc-shaped heads, of the main beam hanging basket parts in the two longitudinal beam structures correspondingly; the rear cross beam extends in parallel to the first direction, the rear web members incline to the first direction, the two rear web members are connected to the two ends of the rear cross beam, and the end, away from the rear cross beam, of each rear web member and one main beam hanging basket part are connected to the connecting position of the middle cross beam. The front fulcrum cable-stayed hanging basket for construction of the main beam of the cable-stayed bridge is high in stability and convenient to operate.
本申请提供一种斜拉桥主梁施工用前支点牵索挂篮及其安装方法。斜拉桥主梁施工用前支点牵索挂篮包括横梁结构和两个纵梁结构。两个纵梁结构沿第一方向间隔设置于索塔塔肢的两侧。横梁结构，固定连接两个纵梁结构，横梁结构包括前横梁、中横梁、后横梁和两个后腹杆，前横梁的两端分别连接于两个纵梁结构中主梁挂篮部和弧形首的连接处，中横梁的两端分别连接于两个纵梁结构中主梁挂篮部背离弧形首的一端，后横梁平行于第一方向延伸，后腹杆倾斜于第一方向，两个后腹杆连接于后横梁的两端，每个后腹杆背离后横梁的一端与一个主梁挂篮部连接于与中横梁的连接处。这种斜拉桥主梁施工用前支点牵索挂篮稳定性高，便于操作。
