Bidirectional dense rib steel bar truss concrete combined non-dismantling formwork
The invention discloses a bidirectional dense rib steel bar truss concrete combined non-dismantling formwork which comprises a crisscrossed latticed steel bar truss and a bottom plate, the crisscrossed latticed steel bar truss is arranged above the bottom plate, and a hollow floor core mold is arranged on the bottom plate and in a grid of the crisscrossed latticed steel bar truss. The steel bar truss comprises a first upper chord rib, a second upper chord rib, rectangular stirrups and V-shaped wave ribs, the first upper chord rib and the second upper chord rib are arranged side by side in parallel, the rectangular stirrups are further arranged on the outer sides of the first upper chord rib and the second upper chord rib, the first upper chord rib and the second upper chord rib are both connected with the V-shaped wave ribs, and the V-shaped wave ribs are connected with the rectangular stirrups. 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. The dense ribs are high, on-site steel bar penetrating is easy, the bottom stressed steel bars are laid on site in a full-length mode, breaking is not needed, reliability is high, and the method is suitable for a secondary-beam-free and large-span fabricated building structure.
本发明公开了一种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，所述底板上、纵横交错呈网格状钢筋桁架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、第二上弦筋、矩形箍筋和V形波浪筋，所述第一上弦筋和第二上弦筋平行并排设置，所述第一上弦筋和第二上弦筋上外侧还设有矩形箍筋，所述第一上弦筋和第二上弦筋均连接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。本发明密肋高度较高，现场钢筋穿设容易，底部受力钢筋现场通长铺设，无需打断，可靠性强，适用于无次梁、大跨度的装配式建筑结构。
