The invention provides a prestressed composite floor slab. The prestressed composite floor slab comprises a concrete prefabricated layer, a concrete cast-in-place layer, a plurality of prestressed steel wires and a plurality of first composite ribs. And the prestressed steel wires are arranged at intervals and are embedded in the concrete prefabricated layer. The first laminated ribs are arranged at intervals, each first laminated rib comprises a first truss upper chord member and a first bending structure, the first truss upper chord members are connected with the top ends of the first bending structures, and the lower portions of the first bending structures are embedded in the concrete prefabricated layer. The upper portion of each first bending structure is embedded in the concrete cast-in-place layer, each first truss upper chord is embedded in the concrete cast-in-place layer, and the concrete cast-in-place layer is connected with the concrete prefabricated layer. The prestressed composite floor slab solves the problems that composite ribs of an existing prestressed composite floor slab are not fully utilized, and materials on the upper portions of the composite ribs are left unused and wasted.
本申请提供了一种预应力叠合楼板，包括混凝土预制层、混凝土现浇层、多根预应力钢丝和多个第一叠合筋。各根预应力钢丝互相间开排布，各根预应力钢丝埋设于混凝土预制层。各个第一叠合筋互相间开排布，各个第一叠合筋包括第一桁架上弦杆和第一弯曲结构，第一桁架上弦杆和第一弯曲结构的顶端连接，各个第一弯曲结构的下部嵌设于混凝土预制层。各个第一弯曲结构的上部嵌设于混凝土现浇层，各个第一桁架上弦杆嵌设于混凝土现浇层，混凝土现浇层和混凝土预制层连接。本申请解决了现有预应力叠合楼板的叠合筋并未被充分利用，存在叠合筋上部分材料被闲置浪费的问题。
