Cast-in-place box girder side formwork back rib and diagonal bracing sleeve supporting system
The invention discloses a cast-in-place box girder side formwork back rib and diagonal bracing sleeve supporting system which comprises double-limb channel steel and telescopic sleeves. The double-limb channel steel comprises upper double-limb channel steel, lower double-limb channel steel and inclined double-limb channel steel; the telescopic sleeves comprise a vertical telescopic sleeve and an inclined strut telescopic sleeve; N vertical telescopic sleeves are arranged between the double-limb channel steel and the lower double-limb channel steel; diagonal bracing telescopic sleeves are arranged at the two ends; and sleeve bolt connecting holes are formed in the upper end and the lower end of the telescopic sleeves. The system has the beneficial effects that the construction operability is high, and the engineering quality of the cast-in-place box girder is guaranteed; a green construction concept is implemented, and an energy-saving and environment-friendly measure of replacing wood with steel is implemented; and a stress system is more stable. Double-limb channel steel is arranged in the transverse bridge direction to serve as supporting points, and diagonal bracing sleeve supporting systems are symmetrically arranged on the two sides of the cast-in-place box girder, so that the supporting rigidity of the web side formwork is improved, and the sliding risk of the side formwork is reduced.
本发明公开了一种现浇箱梁侧模背肋及斜撑套管支撑体系，括双肢槽钢、伸缩套管；双肢槽钢包括上双肢槽钢、下双肢槽钢、斜置双肢槽钢；伸缩套管包括垂直伸缩套管、斜撑伸缩套管；双肢槽钢与下双肢槽钢之间设置有N根垂直伸缩套管；两端均设置有一斜撑伸缩套管；可伸缩套管的上下两端均设置有套管螺栓连接孔。本发明的有益效果在于：施工操作性强，保证了现浇箱梁的工程质量。推行绿色施工理念，实施以钢代木的节能环保措施。受力体系更加稳定。通过双肢槽钢横桥向布置作为支撑点，现浇箱梁两侧对称布置斜撑套管支撑体系，提升了腹板侧模的支撑刚度，减小了侧模滑移的风险。
