The invention provides lightweight concrete composite stairs, and belongs to the technical field of building components. The lightweight concrete composite stairs comprise a ladder beam slab, steppingpiers and corner beam slabs. A steel bar truss of the ladder beam slab, the stepping piers and the corner beam slabs is an integral steel bar truss, and the integral steel bar truss is formed by interlacing and binding or welding a steel beam truss, stepping trusses and corner trusses. The steel bar truss is formed by binding or welding a plurality of rhombic beam frames and crossbeams, each stepping truss is formed by binding or welding a plurality of first triangular powerful frames and crossbeams, and each corner truss is formed by binding or welding a plurality of second triangular powerful frames, third triangular powerful frames and crossbeams. The lightweight concrete composite stairs have the beneficial effects that the stepping trusses and the corner trusses are interlaced with the steel bar truss for installation and connection, thus in combination with the weight of the prefabricated stairs made of lightweight concrete, the bearing capacity can be greatly improved, vibration is reduced, the self-weight of the lightweight concrete composite stairs is reduced, and people feel comfortable when stepping on the stairs.
一种轻质混凝土组合楼梯，属于建筑构件技术领域，包括梯梁板、踏步墩和转角梁板；所述梯梁板、踏步墩和转角梁板的钢筋桁架为整体状的钢筋桁架，该整体状钢筋桁架由钢梁桁架、踏步桁架和转角桁架互相穿插绑接或焊接而成；其中所述钢梁桁架由若干个菱形梁框和横梁绑接或焊接而成；所述踏步桁架由若干个第一三角形强力架和横梁绑接或焊接而成；所述转角桁架由若干个第二三角形强力架、第三三角形强力架和横梁绑接或焊接而成；其有益效果是踏步桁架和转角桁架与钢梁桁架互相交错装接，这样结合轻质混凝土材料制作的预制楼梯的重量可以大大提高承受力，减少震动，并减轻自重且踏步舒适。
