上海泖港桥为直柱形双塔结构(图1),从梁面算起高44m,共需钢筋101t,型钢9.5t,钢板3.5t,共浇混凝土720m~3。塔柱混凝土浇筑按设计分三次进行。第一次从箱梁顶浇至10.70m处;第二次从10.70m浇至26.95m处;第三次从26.95m浇至44m塔顶。塔柱上共11对索,索距为3.25m。每次混凝土浇筑高度为3.25m。塔柱共配制三套半定型模板,一套大头模板。模板为5cm刨光板铺钉白铁皮,龙骨间距为40cm,φ16圆钢做拉杆螺栓。按索管和预埋件位置摆定位角铁,预留洞眼。模板架立时,先随索管安置好短边模板,临时
Shanghai Xianggang Bridge is a straight-column double-tower structure (Figure 1). It is 44 meters high from the beam surface and requires a total of 101 tons of steel, 9.5 tons of steel, 3.5 tons of steel, and 720 m~3 of co-cast concrete. The column concrete pouring is carried out in three separate designs. From the top of the box girder to the first 10.70m; the second from 10.70m to 26.95m; the third from 26.95m to 44m. There are 11 pairs of ropes on the tower, and the cable distance is 3.25m. Each concrete pouring height is 3.25m. The tower column prepared a total of three sets of semi-shaped template, a set of large template. The template is a 5cm planer plate with nails tinned, the spacing between the keel is 40cm, and the φ16 round steel is used as a tie bolt. Position the angle iron according to the position of the cable pipe and the embedded part, and reserve the hole. When the template is erected, the short-edge template is first installed with the cable, and temporary
