Bridge forming linear control method for steel-concrete combined continuous beam bridge
The invention discloses a bridge forming linear control method for a steel-concrete combined continuous beam bridge. The bridge forming linear control method comprises the following construction steps that S1, the zero point of the bending moment of a continuous steel box beam is calculated, and a plurality of pre-segmented position points in the extending direction of the bridge are determined; s2, prefabricating a plurality of sections of steel box girder main bodies which can be sectioned at the set positions in the step S1; s3, after the side span permanent piers and the midspan permanent piers are erected, temporary supports with the corresponding number are erected at the position points with the set number in the S1, and pre-jacking is conducted on the temporary supports; s4, assembling a plurality of sections of steel box girder main bodies to form a continuous steel box girder; s5, unloading for the first time: unloading the continuous steel box girder from the pre-jacking state of the temporary bracket to the contact state of the continuous steel box girder and a midspan permanent pier; s6, bridge deck concrete construction; and S7, unloading for the second time, so that the local self-weight bearing structure of the bridge is transferred from the temporary support to the structure of the bridge, the bridge line shape can be controlled, and the construction quality is guaranteed.
本发明公开了一种钢混组合连续梁桥成桥线形控制方法，包括以下施工步骤：S1.计算连续钢箱梁的弯矩零点并确定在桥梁延伸方向预分段的若干个位置点；S2.预制能够在S1中设定位置分段的若干段钢箱梁主体；S3.在边跨永久墩和跨中永久墩搭设完毕之后，在S1中设定数量的位置点处搭设对应数量的临时支架并在临时支架上进行预顶升；S4.装配若干段钢箱梁主体形成连续钢箱梁；S5.第一次卸载，使连续钢箱梁由临时支架预顶升状态卸载到连续钢箱梁与跨中永久墩接触状态；S6.桥面混凝土施工；S7.第二次卸载，使桥梁局部自重承载结构由临时支架转移至桥梁自身结构，能够控制成桥线形，保证施工质量。
