Concrete pouring construction method for dense rib hollow floor
The invention discloses a dense rib hollow floor concrete pouring construction method. The method comprises the following steps that a coordinate net of a dense rib hollow floor is arranged on a formwork; according to the coordinate net, bottom plate steel bars, longitudinal ribbed beams and transverse ribbed beams are installed on the formwork, and the bottom plate steel bars and the ribbed beams are fixed to the formwork through fixing pieces; a vertical through hole is formed in the center of the membrane shell, the membrane shell is installed in an empty web formed by the longitudinal dense rib beams and the transverse dense rib beams, a top steel bar is installed at the top of the membrane shell, and a connecting piece penetrates through the vertical through hole to connect the bottom plate steel bar with the top steel bar; concrete pouring is conducted at least three times, pouring is conducted along the dense rib beams on the periphery of the membrane shell for the first time, the pouring condition is observed through the vertical through holes, pouring is conducted into the vertical through holes for the second time, and the remaining space of the dense rib beams and the remaining space of the vertical through holes are filled with concrete for the third time. According to the dense rib hollow floor concrete pouring construction method, the membrane shell can be limited, the membrane shell is prevented from moving, and meanwhile the compactness of the concrete at the bottom of the membrane shell can be improved.
本发明公开了一种密肋空心楼盖砼浇筑施工方法，包括以下步骤：在模板上设置密肋空心楼盖的坐标网；根据坐标网，在模板上安装底板钢筋和纵、横密肋梁，并采用固定件将底板钢筋和密肋梁固定在模板上；在膜壳的中心位置设置竖向通孔，将膜壳安装在纵、横密肋梁形成的空腹中，在膜壳顶部安装顶部钢筋，并利用连接件穿过竖向通孔将底板钢筋与顶部钢筋相连；混凝土浇筑：混凝土浇筑至少分三次进行，第一次沿膜壳四周的密肋梁浇筑，通过竖向通孔观察浇筑情况，第二次向竖向通孔内浇筑，第三次将密肋梁和竖向通孔的剩余空间使用混凝土浇满。所述密肋空心楼盖砼浇筑施工方法既能对膜壳进行限位，避免膜壳移动，同时还能提高膜壳底部混凝土密实性。
