Novel fabricated steel-concrete combined steel plate beam
The invention discloses a novel fabricated steel-concrete combined steel plate beam which at least comprises a pi-shaped beam composed of two I-shaped beams and a panel, the end of the pi-shaped beam is wrapped with a cross beam, a support is arranged at the bottom end of the pi-shaped beam, and structural stress ribs are respectively arranged in a panel wet joint and a cross beam wet joint formed between the pi-shaped beams. The simply-supported structure system of the pi-shaped beam is adopted, construction at the pier top is simplified, the problem that a bridge deck slab at the pier top is pulled to crack is solved, and the structural durability is improved; the two I-shaped beams and the panel are designed to be pi-shaped beams, and the two supports are arranged so that the stability problem in the mounting process is solved; transverse stiffeners in the midspan steel cross beam and the steel beam web in the prior art are abandoned, the structure is greatly simplified, the landscape effect is good, maintenance is easy, and the workload is small.
本发明公开了一种新型装配式钢‑混凝土组合钢板梁，至少包括一个由两个工字形梁与面板组成的“π”形梁，所述“π”形梁的端部外包有横梁，在所述“π”形梁的底端设置有支座，所述“π”形梁之间形成的面板湿接缝及横梁湿接缝内分别设置有结构受力筋。本发明采用“π”形梁的简支结构体系，简化墩顶处施工，避免墩顶处桥面板受拉开裂的问题，提高结构耐久性；两个工字形梁和一个面板设计为“π”形梁，且设置两个支座，解决安装过程中的稳定问题；摒弃了现有技术中跨中钢横梁及钢梁腹板中的横向加劲，大幅简化构造，景观效果好，易于养护且工作量小。
