Semi-fabricated honeycomb steel beam and prestressed concrete combined bent cap and construction process
The semi-fabricated honeycomb steel beam and prestressed concrete combined cover beam comprises a prefabricated ultra-high-performance concrete thin-wall shell, a steel reinforcement framework is arranged on a bottom plate of the prefabricated ultra-high-performance concrete thin-wall shell in the length direction, and prestressed tendons are arranged in the length direction of the prefabricated ultra-high-performance concrete thin-wall shell; the two ends of the prestressed tendons penetrate through the steel cushion plate and the prefabricated ultra-high performance concrete thin-wall shell, and the steel reinforcement framework and the prestressed tendons are all packaged in common concrete. Honeycomb steel beams which can be reliably connected with internal concrete and do not affect arrangement of stirrups are arranged on the prefabricated ultra-high performance concrete thin-wall shell, so that the bearing capacity and rigidity requirements in the construction stage and the use stage are improved. According to the bent cap, a temporary support and a formwork do not need to be erected, the construction procedure is greatly simplified, the construction time is shortened, pollution and noise are reduced, and the hoisting difficulty is lowered.
半装配式蜂窝钢梁与预应力混凝土组合盖梁及施工工艺，包括预制超高性能混凝土薄壁外壳，所述预制超高性能混凝土薄壁外壳的底板上沿长度方向设置钢筋骨架，沿预制超高性能混凝土薄壁外壳长度方向布置预应力筋，且预应力筋两端穿过垫钢板及预制超高性能混凝土薄壁外壳设置，所述钢筋骨架及预应力筋均封装于普通混凝土内。在预制超高性能混凝土薄壁外壳设置能与内部混凝土连接可靠、不影响箍筋布置的蜂窝钢梁，来提高施工阶段和使用阶段的承载力和刚度要求。这种盖梁不需要搭设临时支撑及模板，大大简化施工工序，缩短施工时间，减少污染和噪音，降低了吊装的难度。
