The prefabricated prestressed laminated slab comprises a horizontally-arranged bottom plate, a plurality of embedded nuts are arranged in the bottom plate, the lower ends of the embedded nuts are connected with prestressed steel bars and/or distribution bars, and the upper ends of the embedded nuts penetrate through the upper end face of the bottom plate. The invention further discloses a production method, a hoisting method and a construction method of the laminated slab, the embedded nuts are arranged in the laminated slab, so that the surface of the laminated slab is smooth, the laminated slab can be directly laminated on the ground in the vertical direction in a multi-layer mass production mode during production, the structure is simple, production line equipment and steam curing equipment are abandoned, natural curing is adopted, the production cost is reduced, and the production efficiency is improved. The production efficiency is high, and the occupied area of the production line is small. During hoisting and construction, the bolts are arranged in the embedded nuts, the positioning steel bars are arranged on the bolts to be connected with the steel bar net frame, so that the integrity is improved, the bolts not only play a role of a vertical keel, but also play a role of limiting and pressing the steel bar net frame, the construction is convenient, the efficiency is high, the integrity is good, and the cost is low.

    本发明公开了一种预制预应力叠合板,包括水平设置的底板,在底板中设有若干预埋螺母,所述预埋螺母的下端与预应力钢筋和/或分布筋连接,上端贯穿底板的上端面。还公开了其生产方法、吊装方法和施工方法,本发明通过在叠合板中设置预埋螺母,使叠合板表面平整,在生产时能够直接在地面上沿竖向叠合多层批量生产,结构简单,舍弃了生产线设备及蒸汽养护设备,采用自然养护,降低生产成本,生产效率较高,生产线占地面积较小。在吊装和施工时,通过在预埋螺母中设置螺栓,并在螺栓上设置定位钢筋与钢筋网架连接,从而提高了整体性,螺栓不仅起到了竖向龙骨的作用,还能对钢筋网架起到限位和压紧作用,施工方便效率高,整体性好,成本较低。
