Bidirectional dense rib steel bar truss concrete laminated floor cover bottom plate
The invention discloses a two-way dense rib steel bar truss concrete laminated floor system bottom plate which comprises a criss-cross latticed steel bar truss and a bottom plate body, and the criss-cross latticed steel bar truss is arranged above the bottom plate body. A hollow floor core mold is arranged on the bottom plate and in a grid formed by the transverse steel bar trusses and the longitudinal steel bar trusses in a criss-cross mode, each steel bar truss comprises a first upper chord rib and a second upper chord rib, rectangular stirrups are arranged on the outer sides of the first upper chord ribs and the second upper chord ribs, and reinforcing ribs are connected to the two sides of the lower portion of each rectangular stirrup. A bending part is arranged on the reinforcing rib, the reinforcing rib is connected with the lower part of the rectangular stirrup through the bending part, and a reinforcing part is arranged at the lower part of the bending part; the lower portions of the reinforcing ribs are buried in the bottom plate, and the bottom plate is made of concrete or cement mortar. The dense ribs are high in height, reinforcing steel bars are easy to penetrate through on site, the prefabrication rate is high, and the method is suitable for secondary-beam-free and large-span fabricated building structures.
本发明公开了一种双向密肋钢筋桁架混凝土叠合楼盖底板，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，所述底板上、横向钢筋桁架和纵向钢筋桁架纵横交错呈网格状的网格内设有空心楼盖芯模，所述钢筋桁架包括第一上弦筋和第二上弦筋，所述第一上弦筋和第二上弦筋外侧设有矩形箍筋，所述矩形箍筋下部两侧均连接有加强筋，所述加强筋上设有弯折部，所述加强筋通过弯折部与矩形箍筋的下部连接，所述弯折部下部设有加强部件；所述加强筋的下部埋没于底板内，所述底板的材质为混凝土或水泥砂浆。本发明密肋高度较高，现场钢筋穿设容易，预制率高，适用于无次梁、大跨度类装配式建筑结构。
