Combined formwork system structure for cast-in-place box girder through few-support method
The invention provides a few-support-method cast-in-place box girder combined formwork system structure which comprises steel pipe piles arranged on the ground in a driving mode, pile top longitudinal beams are arranged on the tops of the steel pipe piles, pile top cross beams are vertically arranged on the tops of the pile top longitudinal beams, bailey beams are vertically arranged on the tops of the pile top cross beams, and the bailey beams are vertically arranged on the tops of the steel pipe piles. Distribution beams are vertically and evenly laid on the tops of the bailey beams, bowl buckle frames are arranged on the tops of the distribution beams, the top ends of the bowl buckle frames are matched with bottom arc lines of the box beams, longitudinal and transverse sole timbers are arranged on the tops of the bowl buckle frames, and box beam formworks are arranged on the tops of the longitudinal and transverse sole timbers. According to the method, the steel pipe piles driven on the ground serve as supporting piers, the steel pipe piles are matched with the pile top longitudinal beams and the pile top cross beams to provide stable supporting for the bailey beams, the characteristics of large bearing capacity and small deformation of the steel pipe piles and the bailey beams are fully utilized, the supporting strength of the bottom layer is guaranteed, foundation treatment is replaced, the construction speed is increased, and the construction period is shortened.
本发明提供一种少支架法现浇箱梁组合模板体系结构，包括打设于地面的钢管桩，所述钢管桩的顶部设置有桩顶纵梁，所述桩顶纵梁的顶部垂直设置有桩顶横梁，所述桩顶横梁的顶部垂直设置有贝雷梁，所述贝雷梁的顶部设垂直均匀铺设有分配梁，所述分配梁的顶部设置有碗扣架，所述碗扣架的顶端与箱梁的底部弧线相匹配，所述碗扣架的顶部设置有纵横垫木，所述纵横垫木的顶部设置有箱梁模板；本发明中，通过打设于地面的钢管桩作为支撑墩，利用钢管桩配合桩顶纵梁、桩顶横梁对贝雷梁提供稳定支撑，充分利用钢管桩及贝雷梁承载能力大，变形小的特性，保证底层的支撑强度，替代地基处理，提升施工速度，节约施工周期。
