The invention relates to the technical field of steel box girder assembly methods, in particular to a pre-assembly type steel box girder assembly method. Comprising the following steps that S1, all parts in a plurality of lifting supports are transported to a site, the lifting supports are integrally assembled at the positions close to preset bridge piers, the lifting supports are suspended and lifted through a tower crane and placed on a preset bridge floor, and operation is synchronously conducted at the positions of the bridge piers on the other side; s2, the lifting support is moved forwards to the construction position by means of a walking mechanism at the bottom of the lifting support, the walking mechanism is fixed, and overall mounting and positioning of the lifting support are completed; s3, measuring the distance between the lifting equipment and the end part of the bridge floor, and adjusting a suspension point position by virtue of a base assembly at the top of the lifting bracket; the process is simple and clear, the hoisting operation of the steel box girder can be rapidly completed through cooperation of the lifting support and all the components, the displacement operation of the lifting support is simplified, the adjusting efficiency is effectively improved, and the construction time is shortened.
本发明涉及钢箱梁装配方法技术领域,尤其涉及一种预装配式钢箱梁组装方法。包括以下步骤:S1、将多个提升支架中的各部件运输至现场处,并在靠近预设桥墩处对所述提升支架整体进行拼装,塔吊对所述提升支架悬吊提升,放置于预设桥面上,另一侧的桥墩处同步进行;S2、依靠所述提升支架底部的行走机构,将提升支架前移至施工位置,并对所述行走机构固定,完成所述提升支架的整体安装定位;S3、测量提升设备与桥面端部的距离,依靠所述提升支架顶部的底座组件,调整悬挂点位;本发明工序简单明了,依靠提升支架与各个部件之间的配合,能够快速完成对钢箱梁的吊装作业,并且简化提升支架的位移操作,有效提升调整效率,缩短施工时间。
