Sliced assembly type variable cross-section box girder structure and construction method
The invention provides a fragmented assembly type variable cross-section box girder structure and a construction method, each box girder segment box girder comprises a top plate unit, two web plate units and a bottom plate unit, a plurality of web plate vertical ribs are pre-buried in the web plate units, the upper end and the lower end of each web plate vertical rib are respectively connected with a threaded sleeve, and the threaded sleeves are connected with the top plate unit and the bottom plate unit. Vertical rib hole channels are formed in the top plate unit and the bottom plate unit, and vertical ribs penetrate through the vertical rib hole channels of the top plate and the bottom plate and are in threaded connection with the threaded sleeves at the two ends of the web vertical ribs respectively. During hoisting construction of the box girder, the plate units of all the sections are hoisted and connected into a whole section through the vertical ribs. The use of large equipment can be reduced, and the prefabrication construction difficulty and cost are reduced.
本发明提供一种分片装配式变截面箱梁结构及施工方法，每个箱梁节段箱梁包括一顶板单元、两个腹板单元和一底板单元，腹板单元内预埋有多根腹板竖向筋，每根腹板竖向筋上下两端分别连接一螺纹套筒，顶板单元和底板单元内设有竖向筋孔道，顶板和底板竖向筋孔道内穿设竖向筋并分别与腹板竖向筋两端的螺纹套筒螺接。箱梁吊装施工时，各节段的板单元分别吊装并通过竖向筋连接成节段整体。本发明可减少大型设备使用，降低预制施工难度和成本。
