Detachable combined steel bridge deck pavement structure
The invention relates to a detachable combined steel bridge deck pavement structure which comprises a steel bridge deck slab, corrugated steel plates, T-shaped stiffening ribs, ribbed steel bars, ultra-high performance concrete, an asphalt concrete wearing layer and high-strength bolts. Wherein the corrugated steel plate is connected with a top plate of the steel bridge deck slab at the straight section through high-strength bolts, and the corrugated section corresponds to longitudinal stiffening ribs of the steel bridge deck slab; a web of the T-shaped stiffening rib is provided with a hole and is connected with the straight section of the corrugated steel plate by adopting a welding seam along the bridge direction; the ribbed steel bars penetrate through the T-shaped stiffening rib trepanning webs in the transverse bridge direction, and then the ultra-high performance concrete is poured, so that the combined action with the steel bridge deck is realized; and finally, an asphalt concrete wearing layer is poured, and the detachable combined steel bridge deck pavement structure is formed. The detachable combined steel bridge deck pavement structure is reasonable in design, has the advantages of being large in rigidity, light in self weight, convenient to detach and the like, and can effectively improve the fatigue performance of the steel bridge deck slab.
本发明涉及一种可拆卸式组合钢桥面铺装结构，包括钢桥面板、波折钢板、T形加劲肋、带肋钢筋、超高性能混凝土、沥青混凝土磨耗层、高强螺栓；其中，所述波折钢板在平直段采用高强螺栓与钢桥面板顶板连接，波折段与钢桥面板纵向加劲肋对应布置；所述T形加劲肋腹板开孔，顺桥向采用焊缝与波折钢板平直段连接；所述带肋钢筋横桥向穿过T形加劲肋开孔腹板，然后浇筑超高性能混凝土，实现与钢桥面板共同作用；最后浇筑沥青混凝土磨耗层，形成可拆卸式组合钢桥面铺装结构。本发明提供一种可拆卸式组合钢桥面铺装结构设计合理，具有刚度大、自重轻、方便拆卸等优点，能有效提高钢桥面板的疲劳性能。
