Construction supporting system and method for steel-concrete combined section of hybrid beam cable-stayed bridge
The invention discloses a hybrid beam cable-stayed bridge steel-concrete combined section construction supporting system and method. An upper steel-concrete connecting structure is mounted at the top of a steel box beam lower bearing structure; the lower bearing structure of the steel box girder comprises a triangular bracket bearing support formed by welding a 0 # block support steel pipe, a horizontally-connected supporting rod and an inclined supporting rod end to end. The triangular bracket bearing support is sequentially provided with a transverse bridge direction bearing beam and a longitudinal distribution structure from bottom to top, and a plurality of sets of bearing beams are fixedly installed at the top of the longitudinal distribution structure at certain intervals. The upper steel-concrete connecting structure comprises tie section steel arranged on the two transverse sides of the bridge and used for temporarily fixing the 0 # block concrete beam section, the first steel box beam and the second steel box beam, and transverse stilling section steel arranged in the middle deviating towards the transverse direction of the bridge. The supporting system adopts the triangular bracket support, so that a pile foundation is prevented from being driven in water to serve as a floor stand supporting foundation, the safety influence of differential settlement on the overall rigidity, stability and the like of the support is eliminated, and the supporting system is convenient to install, small in steel consumption, economical and practical.
本发明公开了一种混合梁斜拉桥钢‑砼结合段施工支撑系统及方法，钢箱梁下部承重结构的顶部安装有上部钢‑砼连接结构；所述钢箱梁下部承重结构包括由0#块支架钢管、平连支撑杆与斜向支撑杆首尾焊接形成的三角形牛腿承重支架；三角形牛腿承重支架从下往上依次设置横桥向承重梁与纵向分配结构，纵向分配结构的顶部安装一定间距固定有多组垫梁；所述上部钢‑砼连接结构包括布置在桥梁横向两侧，用于临时将0#块混凝土梁段与第一钢箱梁和第二钢箱梁进行固定的拉结型钢，以及布置在偏向桥梁横向中间的横向消力型钢。此支撑系统采用三角牛腿支架可以避免采用在水中打设桩基础作为落地支架支撑基础，消除不均匀沉降对支架整体刚度、稳定等安全影响，安装方便，用钢量小，经济实用。
