Steel bar truss concrete prefabricated slab, laminated slab and manufacturing method
The invention provides a steel bar truss concrete prefabricated slab, a laminated slab and a manufacturing method. The steel bar truss concrete prefabricated slab comprises a concrete bottom slab, a plurality of parallel stressed steel bars and a plurality of steel bar trusses, the concrete bottom plate comprises a flat plate with the preset thickness ranging from 25 mm to 35 mm. The load-bearing steel bars and the steel bar truss are parallel to each other and are arranged in the concrete bottom plate in the length direction, and the top of the steel bar truss is higher than the upper surface of the concrete bottom plate. By reducing the thickness of the concrete precast slab, the thickness of the laminated slab after the cast-in-place surface layer is poured on the precast slab is the same as that of a traditional cast-in-place structural floor slab, and concrete waste is avoided; lower chord steel bars of the steel bar truss are used as load-bearing steel bars, and steel bar waste is reduced. The structure of closely splicing the slab joints is adopted between the prefabricated slabs, and the slab bottom of the laminated slab does not need to be lapped by reinforcing steel bars in the width direction, so that waste of the reinforcing steel bars is reduced.
本发明提供了一种钢筋桁架混凝土预制板、叠合板及制造方法，其中的钢筋桁架混凝土预制板包括混凝土底板和若干相互平行的受力钢筋及钢筋桁架；所述混凝土底板包括预设厚度为25mm‑35mm的平板；所述受力钢筋及钢筋桁架相互平行且沿长度方向设置于所述混凝土底板内，所述钢筋桁架的顶部高于所述混凝土底板的上表面。通过降低混凝土预制板厚度，实现了预制板浇筑现浇面层后的叠合板厚度与传统现浇结构楼板厚度相同,避免了混凝土浪费；钢筋桁架的下弦钢筋作为受力钢筋使用，减少了钢筋浪费；通过预制板之间采用密拼板缝的构造，叠合板板底在宽度方向上不需钢筋搭接，减少了钢筋浪费。
