Hyperbola fish belly type cast-in-place beam formwork supporting system
The invention discloses a hyperbolic-curve fish-bellied cast-in-place beam formwork supporting system which comprises a disc buckle support arranged on a concrete cushion layer in a supported mode and a truss distribution beam erected on an adjustable jacking of the disc buckle support, and the truss distribution beam comprises two fish-bellied truss beams which are the same in structure and are symmetrically arranged. The fish-bellied truss girder comprises a first arc-shaped truss, a second arc-shaped truss and a third arc-shaped truss which are sequentially connected, the adjacent first arc-shaped truss and second arc-shaped truss are fixedly connected through fasteners, and the adjacent second arc-shaped truss and third arc-shaped truss are fixedly connected through fasteners. The fish-bellied truss girder can effectively overcome the horizontal load generated by pouring concrete, the curved control requirement of a variable curvature arc at the bottom of a hyperbolic curve fish-bellied cast-in-place beam can be met by utilizing the curved upper chord component, and under the supporting action of the combination of the disc buckle bracket and the truss distribution girder, the curved control requirement of the variable curvature arc at the bottom of the hyperbolic curve fish-bellied cast-in-place beam can be met. And the stress requirements of the hyperbolic fish-bellied cast-in-place beam in different construction stages can be met.
本发明公开了一种双曲线鱼腹式现浇梁模板支撑体系，包括支设在混凝土垫层上的盘扣支架和架设在盘扣支架的可调顶托上的桁架分配梁，桁架分配梁包括两个结构相同且对称布设的鱼腹式桁架梁，鱼腹式桁架梁包括依次连接的第一弧形桁架、第二弧形桁架和第三弧形桁架，相邻的第一弧形桁架与第二弧形桁架之间以及相邻的第二弧形桁架与第三弧形桁架之间均通过扣件固定连接。本发明的鱼腹式桁架梁能够有效克服浇筑混凝土产生的水平荷载，利用曲线形上弦杆组件能够满足双曲线鱼腹式现浇梁底部的变曲率弧的曲线形控制需求，在盘扣支架和桁架分配梁相结合的支撑作用下，能够满足双曲线鱼腹式现浇梁在不同施工阶段的受力要求。
