Fabricated box girder with embedded concrete-filled steel tube stiff framework arch
The invention discloses a fabricated box girder with an embedded steel tube concrete stiff framework arch, and belongs to the technical field of box girder construction structure.A whole box girder is formed by box girder sections which are spliced in sequence, pouring section grooves are formed in the box girder sections, pouring through grooves are formed after splicing, an arch-shaped framework is arranged in the pouring through grooves, and before pouring, the arch-shaped framework is arranged in the box girder sections; concrete can be poured through the pouring holes by sealing the two ends of the box girder, the concrete flows into the pouring through grooves, and after solidification, the arch-shaped framework serves as a structure for connecting all the box girder sections and cannot be cut off from the splicing position; according to the box girder structure of the structure, when the box girder structure bears the upper load and the self-weight load, the arched framework bears the main bending moment, compared with a traditional prestress box girder, the construction quality and efficiency are guaranteed more easily, downwarping deformation caused by prestress loss and concrete creep is avoided, the follow-up maintaining and reinforcing pressure is relieved, and the service life of the box girder structure is prolonged. Wherein the long steel pipes can be circular or rectangular and have different bearing capacities respectively.
本发明公开了一种内嵌钢管混凝土劲性骨架拱的装配式箱梁，属于箱梁施工结构领域技术领域，通过依次拼接的箱梁段形成箱梁整体，通过在箱梁段内开通浇筑段槽，拼接后形成浇筑通槽，浇筑通槽内设置拱状骨架，在浇筑前，对箱梁两端进行封闭即可通过浇筑孔浇筑混凝土，混凝土流入浇筑通槽内，凝固后，拱状骨架作为连接各个箱梁段的结构，不会从拼接处截断；此结构的箱梁结构，当承受上部荷载及自重荷载作用时，拱形骨架承担主要弯矩，相较于传统预应力箱梁，更容易保证施工质量和效率，且避免预应力损失和混凝土徐变造成的下挠变形，减轻后续维养和加固压力，其中长钢管可选择圆形和矩形，分别具有不同的承载能力。
