Disassembly-free cement-based bottom plate steel bar truss floor support plate
The invention provides a disassembly-free cement-based bottom plate steel bar truss floor support plate. The disassembly-free cement-based bottom plate steel bar truss floor support plate comprises a main body structure and a plurality of truss assemblies. Wherein the main body structure comprises a metal grid piece and a cement-based bottom plate, and the metal grid piece is poured in the bottom of the cement-based bottom plate; each truss assembly comprises two web member steel bars with feet, an upper chord steel bar and two lower chord steel bars. According to the disassembly-free cement-based bottom plate steel bar truss floor support plate, the bottoms of the web member steel bars with the feet are welded to the upper portions of the metal grid pieces through the butt-welding technology, full-mechanical and industrialized welding can be adopted for welding, manpower is effectively reduced, displacement between the metal grid pieces and the web member steel bars with the feet can be reduced to the maximum extent after welding, and the construction efficiency is improved. The process of fixing the metal grid piece and the web member reinforcing steel bars with feet can be omitted, the overall bearing strength is large, the borne construction load is large, the overall weight is light, large mechanical construction is not needed, and the construction difficulty can be effectively lowered.
本发明提供了一种免拆式水泥基底板钢筋桁架楼承板，包括：主体结构以及若干组桁架组件。其中，主体结构包括金属网格片以及水泥基底板，金属网格片被浇筑在水泥基底板的底部内部；其中，每组桁架组件均包括两个带脚腹杆钢筋、一根上弦钢筋以及两根下弦钢筋。本发明提供的免拆式水泥基底板钢筋桁架楼承板，将带脚腹杆钢筋的底部均通过碰焊工艺与金属网格片的上部焊接，可采用全机械化工业化进行焊接，有效减少人力，且焊接以后能最大程度减少金属网格片与带脚腹杆钢筋之间的位移，可减少一道金属网格片与带脚腹杆钢筋固定的工序，整体承力强度较大，承受施工荷载较大，整体重量轻无需大型机械化施工，可有效降低施工难度。
