Cast-in-place box girder arc-shaped cantilever inclined web wing plate supporting structure and construction method thereof
The invention provides a cast-in-place box girder arc-shaped cantilever inclined web wing plate supporting structure and a construction method thereof. The supporting structure comprises a disc buckle supporting frame, an arc-shaped truss, a batten keel, a first horizontal connecting piece, a reinforcing piece and an arc-shaped formwork used for supporting a cast-in-place box girder arc-shaped cantilever inclined web wing plate. Straight parts at the bottoms of the arc-shaped trusses are installed on the top side of the disc buckle supporting frame, the multiple arc-shaped trusses are vertically arranged at intervals, every two adjacent arc-shaped trusses are detachably connected through a first horizontal connecting piece, one end of each reinforcing piece is fixedly connected to the corresponding first horizontal connecting piece, and the other end of each reinforcing piece is fixedly connected to the disc buckle supporting frame. The batten keels are arranged on the top sides of the semi-arc arch portions of the arc-shaped trusses at intervals, and the arc-shaped formworks are laid on the top sides of the batten keels. Compared with the prior art, the supporting structure adopts the supporting form that the arc-shaped truss is matched with the arc-shaped formwork, and the problems existing when a set-shaped steel formwork structure and a double-spliced steel pipe keel are matched with a wood formwork structure are solved.
本发明提供了提供一种现浇箱梁弧形悬臂斜腹翼板支撑结构及其施工方法，所述支撑结构包括盘扣支撑架、弧形桁架、木方龙骨、第一水平连接件、加固件和用于支撑现浇箱梁弧形悬臂斜腹翼板的弧形模板；弧形桁架底部的平直部安装于盘扣支撑架的顶侧，多个弧形桁架竖向设置且相互间隔，相邻的两个弧形桁架通过第一水平连接件可拆卸连接，加固件的一端固定连接于第一水平连接件，另一端固定连接于盘扣支撑架；多个木方龙骨间隔设置于弧形桁架半弧拱部的顶侧，弧形模板铺设于多个木方龙骨的顶侧。相较于现有技术，本发明支撑结构采用弧形桁架配合弧形模板的支撑形式，克服了定型钢模板结构和双拼钢管龙骨配合木模板结构存在的问题。
