Novel steel bar truss composite floor slab
The invention discloses a novel steel bar truss composite floor slab. The novel steel bar truss composite floor slab comprises a necking type profiled steel sheet, a concrete prefabricated layer and a steel bar truss, wherein the steel bar truss comprises an upper chord steel bar, a lower chord steel bar and a truss abdomen supporting steel bar; the truss abdomen supporting steel bar is welded on the upper chord steel bar and the lower chord steel bar to form the steel bar truss; and the steel bar truss is welded on the necking type profiled steel sheet through the lower chord steel bar. According to the novel steel bar truss composite floor slab, the necking type profiled steel sheet is adopted so that the binding power between the profiled steel sheet and lower-layer concrete is improved and the thickness of the prefabricated layer is reduced; the novel steel bar truss composite floor slab is combined with the suitable steel bar truss and the strength of the upper chord steel bar and the lower chord steel bar of the steel bar truss is sufficiently utilized; transverse steel bars are paved on site and bidirectional plate reinforcement is easily realized; furthermore, the concrete below the necking type profiled steel sheet can be used as a protection layer of the lower chord steel bar and the profiled steel sheet; the effect of the profiled steel sheet is effectively utilized and the strength and rigidity of a prefabricated part are enhanced; and the problems of beauty, fireproof spraying and anticorrosion maintenance do not need to be considered.
本发明公开了一种新型钢筋桁架叠合楼板，包括缩口型压型钢板、混凝土预制层和钢筋桁架，钢筋桁架包括上弦钢筋、下弦钢筋和桁架腹部支撑钢筋，桁架腹部支撑钢筋焊接在上弦钢筋、下弦钢筋上构成钢筋桁架，钢筋桁架通过下弦钢筋焊接在缩口型压型钢板上，本发明采用缩口型压型钢板，提高压型钢板与下层混凝土间的粘结力，减小预制层厚度；与合适的钢筋桁架组合，充分利用钢筋桁架上下弦筋强度，现场铺设横向钢筋，轻松实现双向板配筋；此外，缩口型压型钢板下方混凝土，既可充当下弦钢筋和压型钢板的保护层，有效利用压型钢板的作用，增强预制构件强度及刚度，也无需再考虑美观、防火喷涂及防腐维护的问题。
