Prefabricated concrete bottom plate integrated with truss steel bars and prestressed steel wire meshes
The invention discloses a prefabricated concrete bottom plate integrated with truss steel bars and a prestressed steel wire mesh, which comprises a concrete bottom plate, the middle layer of the concrete bottom plate is provided with a pre-tensioned steel wire mesh, and the upper end of the concrete bottom plate is provided with a plurality of groups of steel bar trusses which are transversely distributed at equal intervals; upper chord steel bars and lower chord steel bars are arranged at the upper ends and the lower ends of the steel bar trusses correspondingly, and the lower chord steel bars are embedded in the concrete bottom plate. The invention relates to a concrete bottom plate, in particular to a prefabricated concrete bottom plate integrating truss steel bars and a prestressed steel wire mesh, and belongs to the technical field of the building industry. According to the prefabricated concrete bottom plate, the problems of an existing concrete composite floor slab, an existing steel bar truss floor support slab and an existing prestressed steel pipe truss composite floor slab are solved, and in addition, due to the existence of the transverse slab bottom constructional steel bars and the transverse erecting steel bars on the upper chord portion of the steel bar truss, the prefabricated slab has the bi-directional stress characteristic; compared with an existing steel bar truss floor support plate, the prefabricated concrete bottom plate has larger transverse width.
本发明公开了集成桁架钢筋及预应力钢丝网的预制混凝土底板，包括混凝土底板，所述混凝土底板中层设有预张拉钢丝网，所述混凝土底板上端设有多组呈横向等距分布的钢筋桁架，所述钢筋桁架上端和下端分别设有上弦钢筋和下弦钢筋，所述下弦钢筋埋入混凝土底板。本发明涉及一种混凝土底板，特别涉及集成桁架钢筋及预应力钢丝网的预制混凝土底板，属于建筑行业技术领域。本发明技术方案除了解决了现有的混凝土叠合楼板、钢筋桁架楼承板和预应力钢管桁架叠合楼板存在的问题之外，由于本发明中横向板底构造钢筋和钢筋桁架上弦部位横向架立钢筋的存在，使得预制板呈现双向受力特点，将比现有钢筋桁架楼承板具有更大的横向宽度。
