Construction method of fabricated reinforced concrete composite bridge
The invention provides a construction method of an assembly type reinforced concrete composite bridge, which comprises the following steps: S1, manufacturing prefabricated bridge deck slabs of two specifications, arranging a T-shaped pre-embedded steel plate and a linear pre-embedded steel plate at the bottom of each prefabricated bridge deck slab, and preserving heat and moisture to reach the design strength; s2, a steel box girder is manufactured, two sets of jig frames are arranged side by side at intervals, a steel box bottom plate, a steel box web and a steel box diaphragm plate are sequentially installed on the two sets of jig frames correspondingly, manufacturing of a first steel box and a second steel box is completed, a steel cross beam is positioned and installed between the first steel box and the second steel box, the linear size is adjusted and rechecked, and the whole section is symmetrically welded to form a unified whole; and S3, the prefabricated bridge deck slabs are hoisted to the position over the steel box girder, so that the T-shaped pre-embedded steel plates are in butt joint with the steel box diaphragm plates and the steel box webs, and the linear pre-embedded steel plates between the adjacent prefabricated bridge deck slabs are in butt joint. According to the invention, the weight of the bridge is reduced, and effective connection between the prefabricated bridge deck slab and the steel box girder is increased.
本发明提供了一种装配式钢混叠合桥梁的施工方法，包括：S1，制作两种规格的预制桥面板，每块预制桥面板的底部分别布置有T型预埋钢板与一字型预埋钢板，保温保湿养护至设计强度；S2，制作钢箱梁，间隔并列布置两组胎架，在两组所述胎架上分别依次安装钢箱底板、钢箱腹板以及钢箱横隔板，完成第一钢箱与第二钢箱的制作，在第一钢箱与第二钢箱之间定位安装钢横梁，调整复核线型尺寸，整段对称焊接形成统一整体；S3，将预制桥面板吊装至钢箱梁正上方，使得T型预埋钢板与钢箱横隔板、钢箱腹板对接，相邻预制桥面板之间的一字型预埋钢板对接。通过本发明的公开，减轻了桥梁的重量，同时增加了预制桥面板与钢箱梁之间的有效连接。
