Sloping bed step stair beam structure for large-span stair and application method thereof
The invention discloses a sloping bed step stair beam structure for a large-span stair and an application method thereof. The sloping bed step stair beam structure comprises a sloping bed tread steelreinforcement framework and a cement wrapping body attached to the sloping bed tread steel reinforcement framework. The sloping bed tread steel reinforcement framework comprises a sloping bed tread steel reinforcement framework frame, longitudinal steel reinforcement groups arranged on the sloping bed tread steel reinforcement framework frame and stirrups bundled on the sloping bed tread steel reinforcement framework frame. The cross section of the sloping bed tread steel reinforcement framework is a trapezoidal sloping bed tread steel reinforcement cage, and the bottom end of the cross section of the sloping bed tread steel reinforcement framework is a bevel. The horizontal included angle of the bevel is beta. The cement wrapping body and the sloping bed tread steel reinforcement framework are poured into a whole to form the sloping bed step stair beam structure of an upper step tread and a lower step tread. The calculated span of stair plates is reduced. The problem that stair platesof a large-span cast-in-place concrete slab stair are too thick, and the clear height is affected is solved. The load of the large-span cast-in-place concrete slab stair can be dispersed and transmitted. Meanwhile, the problem that the stair plates of the large-span cast-in-place concrete slab stair are too thick, and the clear height is affected is solved.
本发明公开了一种用于大跨度楼梯的斜底踏步梯梁结构及使用方法，包括斜底梯面钢筋骨架和附着在斜底梯面钢筋骨架上的水泥包覆体；斜底梯面钢筋骨架包括斜底梯面钢筋骨架框体、设在斜底梯面钢筋骨架框体上的纵向钢筋组和绑扎在斜底梯面钢筋骨架框体上的箍筋，斜底梯面钢筋骨架的截面为梯形的斜底梯面钢筋笼，截面的底端为斜面，斜面的水平夹角为β；水泥包覆体与斜底梯面钢筋骨架浇筑为一体，构成上台阶梯面和下台阶梯面的斜底踏步梯梁结构。减小了梯段板的计算跨度，解决大跨度现浇混凝土板式楼梯梯板过厚而影响净高的情况，能够将大跨度现浇混凝土板式楼梯荷载分散传递，同时解决了大跨度现浇混凝土板式楼梯梯板过厚而影响净高的难题。
