Strip steel cantilever supporting plate composite beam for cable-stayed bridge
The invention discloses a strip steel cantilever supporting plate composite beam for a cable-stayed bridge, which comprises a bridge deck slab, steel main beams are fixedly arranged at the two ends of the bottom of the bridge deck slab, steel cross beams are fixedly arranged between the steel main beams, and wing-shaped steel cantilevers are fixedly arranged on webs of the steel main beams at equal intervals; a cantilever top plate is laid at the top ends of the steel cantilevers, first stiffening plates are fixedly arranged between the cantilever top plate and the connecting ends of the steel cantilevers at equal intervals, cantilever longitudinal beams extending in the bridge direction are jointly fixed to the side ends of the steel cantilevers, and second stiffening plates perpendicular to the steel cantilevers are fixedly arranged at the bottom ends of the steel cantilevers. According to the strip steel cantilever supporting plate composite beam, the width of the bridge deck slab of the composite beam can be reduced, and the steel cantilever supporting plates are used for assisting the steel main beam and the bridge deck slab in bearing longitudinal pressure.
本发明公开了一种斜拉桥用带钢悬臂撑板组合梁，包括桥面板，桥面板的底部两端固定设置有钢主梁，钢主梁之间固定设置有钢横梁，所述钢主梁的腹板等间距固定排列有翼状的钢悬臂；所述钢悬臂的顶端铺设有悬臂顶板，悬臂顶板与钢悬臂的连接端之间等间距的固定设置有第一加劲板，钢悬臂侧端共同固定有顺桥向延长的悬臂纵梁，钢悬臂底端均固定设置有垂直于钢悬臂的第二加劲板。本发明旨在提供一种能够减少组合梁桥面板宽度，利用钢悬臂撑板辅助钢主梁和桥面板承担纵向压力的组合梁。
