Construction method of superposed beam bridge floor flange of cable-stayed bridge
The invention discloses a construction method of a superposed beam bridge floor flange of a cable-stayed bridge. The construction method comprises the following steps that steel formworks are sequentially hoisted on the bridge floor flange; the transverse overhanging rod pieces are arranged on the bridge floor at intervals, the inner ends of the transverse overhanging rod pieces are fixed, the outer ends of the transverse overhanging rod pieces are suspended towards the outside of the bridge, longitudinal overhanging rod pieces are arranged on the transverse overhanging rod pieces in a crossing mode, and first pull rod holes are formed in the connecting positions of the longitudinal overhanging rod pieces and the transverse overhanging rod pieces; first pull rods are installed in the first pull rod holes, one ends of the first pull rods are fixed to the longitudinal cantilever rod pieces, and the other ends of the first pull rods penetrate through the steel formwork and are fixed; and a second pull rod is mounted at the outer end of each transverse overhanging rod piece, and the second pull rods pull the tops of the steel formworks. According to the construction method of the superposed beam bridge floor flange of the cable-stayed bridge, a stress system of the steel formwork and the first pull rod is adopted for construction, the second pull rod is used for pulling the top of the steel formwork to achieve reinforcement, the construction difficulty is lowered, the construction progress is guaranteed, meanwhile, investment of mechanical equipment and materials is reduced, and the cost is reduced.
本发明公开了一种斜拉桥叠合梁桥面翼缘的施工方法，包括以下步骤：在桥面翼缘依次吊装钢模板；各横向悬挑杆件彼此间隔地设置在桥面上，内端固定，外端向桥外悬空，横跨在各横向悬挑杆件上设置有纵向悬挑杆件，纵向悬挑杆件与各横向悬挑杆件的连接处均设有第一拉杆孔；在各第一拉杆孔上安装第一拉杆，第一拉杆的一端固定在纵向悬挑杆件上，另一端穿过钢模板并固定；在各横向悬挑杆件的外端安装第二拉杆，第二拉杆牵引钢模板的顶部；此斜拉桥叠合梁桥面翼缘的施工方法采用钢模板加第一拉杆的受力体系施工，并利用第二拉杆牵引钢模板的顶部实现加固，降低了施工难度，保证施工进度的同时，减少了机械设备及材料的投入，节约了成本。
