Prefabricated UHPC beam component and beam-slab connecting structure
The prefabricated UHPC beam component comprises a prefabricated beam made of UHPC, the prefabricated beam comprises a bottom plate and side plates arranged on the two opposite sides of the bottom plate, a pouring groove with an upward opening is formed between the bottom plate and the side plates, and a steel framework is arranged in the prefabricated beam; the steel framework comprises an upper angle rib arranged in the upper end of the side plate and a lower angle rib arranged in the lower end of the side plate, the upper angle rib and the lower angle rib extend in the length direction of the precast beam, the upper angle rib and the lower angle rib are sleeved with an outer stirrup, the bottom edge of the outer stirrup is pre-buried in the bottom plate, and the side edge of the outer stirrup is pre-buried in the side plate. The self-weight is reduced, the bending resistance is improved, and the erection of supports on the lower side of the precast beam can be reduced. In addition, the invention also provides a prefabricated UHPC beam plate connecting structure which comprises the prefabricated UHPC beam component, and a template and a support do not need to be erected during construction.
本发明公开了一种预制UHPC梁构件，包括由UHPC制成的预制梁，预制梁包括底板和设置在底板相对两侧的侧板，底板和侧板之间形成开口向上的浇筑槽，预制梁内设置有钢骨架；钢骨架包括设置在侧板的上端内的上角筋和设置在侧板的下端内的下角筋，上角筋和下角筋均沿预制梁的长度方向延伸，上角筋和下角筋上套设置有外箍筋，外箍筋的底边预埋在底板内，外箍筋的侧边预埋在侧板内。减轻了自重和提高了抗弯性能，可减少预制梁下侧支撑的搭设。另外，也提出一种预制UHPC梁板连接结构，包括上述预制UHPC梁构件，施工时，不需要搭设模板和支撑。
