Fabricated steel-concrete combined bridge deck structure
The invention relates to a fabricated steel-concrete combined bridge deck structure. The fabricated steel-concrete combined bridge deck structure comprises a steel top plate, U-shaped longitudinal ribs, an upper transverse partition plate, a lower transverse partition plate, a reinforcing mesh structure arranged on the steel top plate and a concrete structure layer connected with the steel top plate through connecting pieces. A double-sided fillet weld is arranged at the joint of the U-shaped longitudinal rib and the steel top plate; a trapezoid through hole and a U-shaped through hole are formed in the upper transverse partition plate, the bottom of the trapezoid through hole is connected with the top of the U-shaped through hole, the two ends of the U-shaped through hole are semicircular, and the radius of each semicircular arc is larger than the distance from the bottom edge of the U-shaped through hole to the bottom edge of the trapezoid through hole. The typical fatigue vulnerable part of the steel bridge deck adopts a double-sided fillet weld design, novel open holes are formed in the crossed parts of the longitudinal ribs and the transverse partition plates, meanwhile, the concrete structure layer is introduced, and a collaborative stress system is formed through the shearing force connecting pieces; the problems of frequent fatigue cracking of typical construction details of an orthotropic steel bridge deck slab structure and damage to bridge deck pavement in the prior art are solved.
本申请涉及一种装配式钢‑混凝土组合桥面板结构，它包括钢顶板、U形纵肋、上部横隔板、下部横隔板、设于钢顶板上的钢筋网结构以及通过连接件与钢顶板相连接的混凝土结构层；U形纵肋和钢顶板的连接处设置有双面角焊缝；上部横隔板上设置有梯形通孔和U型通孔，梯形通孔的底部与U型通孔的顶部连接，U型通孔两端为半圆弧型，半圆弧的半径大于U型通孔的底边到梯形通孔底边的距离。本发明在钢桥面板典型疲劳易损部位采用双面角焊缝设计，并在纵肋与横隔板交叉部位设置新型开孔，同时引入混凝土结构层，并通过剪力连接件形成协同受力体系，解决现有技术中正交异性钢桥面板结构典型构造细节疲劳开裂频发和桥面铺装损坏两类病害问题。
