Bidirectional dense rib steel bar truss concrete combined non-dismantling formwork for hollow floor system
The bidirectional dense rib steel bar truss concrete combined non-dismantling formwork comprises a criss-cross latticed steel bar truss and a bottom plate, the criss-cross latticed steel bar truss is arranged above the bottom plate, the steel bar truss comprises two upper chord ribs, rectangular stirrups and V-shaped wave ribs, and the two upper chord ribs, the rectangular stirrups and the V-shaped wave ribs are arranged side by side in parallel. The upper chord ribs are connected with V-shaped wave ribs, the lower portions of the V-shaped wave ribs are partially buried in the bottom plate, and the bottom plate is made of concrete or cement mortar. An upper cover plate is arranged over a grid formed by the transverse steel bar trusses and the longitudinal steel bar trusses in a criss-cross mode, steel bar meshes are embedded in the upper cover plate, and a closed light supporting structure is arranged under the upper cover plate. The proportion of concrete needing to be poured on site and steel bars laid on site is low, the prefabrication rate is high, and the method is suitable for secondary-beam-free and large-span fabricated building structures.
本发明公开了用于空心楼盖的双向密肋钢筋桁架混凝土组合免拆模板，包括纵横交错呈网格状的钢筋桁架和底板，所述纵横交错呈网格状的钢筋桁架设在底板的上方，所述钢筋桁架包括平行并排设置的两根上弦筋、矩形箍筋和V形波浪筋，所述上弦筋均连接V形波浪筋，所述V形波浪筋下部部分埋没于所述底板内，所述底板的材质为混凝土或水泥沙浆。所述横向钢筋桁架和纵向钢筋桁架纵横交错呈网格状的网格正上方设有上盖板，所述上盖板内部埋设有钢筋网片，所述上盖板的正下方设有封闭的轻质支撑结构。本发明现场需要浇筑的混凝土和现场铺设的钢筋占比较低，预制率高，适用于无次梁、大跨度类装配式建筑结构。
