Construction method for connection of steel concrete connection segment and steel box girder
The invention discloses a construction method for connecting a steel concrete connecting section and a steel box girder, which comprises the following steps of: 1, hoisting the corresponding steel box girder to a corresponding position of the steel concrete connecting section, and leveling and correcting; secondly, the steel box girders, the steel concrete connecting sections and the external connecting parts of the adjacent steel box girders are welded, and preliminary connecting and fixing of the steel box girders are achieved; thirdly, the operation in the second step is repeated, meanwhile, constructors enter the steel box girders which are preliminarily connected and fixed, and welding operation is conducted on the steel concrete connecting sections and the inner connecting parts of the steel box girders; step 4, performing detection and defect repair on a completed welding spot welding seam; according to the construction method, the positioning parts are manufactured when the connecting ends of the steel concrete connecting sections and the steel box girder are prefabricated in a factory, and the problem that the steel box girder is difficult to position during hoisting is solved; and meanwhile, when the steel box girder is hoisted, welding operation of the steel box girder and the steel concrete connecting section is conducted synchronously, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种钢砼连接节段与钢箱梁连接的施工方法，包括以下步骤：步骤一、将相应的钢箱梁吊运至钢砼连接节段的对应位置处，并进行调平校正；步骤二、将钢箱梁与钢砼连接节段和相邻钢箱梁的外部连接部进行焊接作业，实现钢箱梁的初步连接固定；步骤三、重复步骤二操作，同时施工人员进入已进行初步连接固定的钢箱梁内部，对钢砼连接节段和钢箱梁的内部连接部进行焊接作业；步骤四、对已完成的焊接点焊缝进行检测及缺陷修补；本发明中的施工方法通过将钢砼连接节段与钢箱梁的连接端在工厂预制时制作出定位部，解决了钢箱梁吊装难定位问题；同时在对钢箱梁进行吊装时同步进行钢箱梁与钢砼连接节段的焊接作业，缩短施工周期，降低施工成本。
