Post-pouring belt structure of anti-leakage building floor slab and pouring method
The invention relates to a post-pouring belt structure for an anti-leakage building floor slab. The post-pouring belt structure includes the building floor slab lower with a straight joint, inclined notches are cut in the upper edge and the lower edge of the side, facing the straight joint, of the building floor slab, a lower layer post-pouring belt and an upper layer post-pouring belt are formedin the straight joint in a pouring mode, steel bars at the bottom of the straight joint are embedded in the lower layer post-pouring belt, and the thickness of the lower layer post-pouring belt is less than 1/2 of the thickness of the building floor slab. The post-pouring belt structure has the beneficial effects that the arrangement of the notches increases the contact area between the lower layer post-pouring belt and the upper layer post-pouring belt with the building floor slab, increases the degree of occlusion, and reduces the occurrence risk of cracks between the lower layer post-pouring belt and the upper layer post-pouring belt with the building floor slab in a later period; and pouring is carried out separately to form the lower layer post-pouring belt and the upper layer post-pouring belt to prevent the situation of the segregation of concrete due to over-vibrating of the concrete caused by the small amount of concrete in a one-time pouring forming, the structural strength of the concrete is ensured, and the risk of later leakage is reduced.
本发明涉及一种防渗漏建筑楼板后浇带结构，包括预留有直槎的建筑楼板，建筑楼板朝向直槎一侧的上边缘和下边缘分别开凿有倾斜的豁口，直槎中浇筑形成下层后浇带和上层后浇带，位于直槎底部的钢筋包埋在下层后浇带中，下层后浇带的厚度小于建筑楼板厚度的1/2。有益效果是：豁口的设置增加下层后浇带、上层后浇带与建筑楼板之间的接触面积，增大咬合程度，减少后期下层后浇带、上层后浇带与建筑楼板之间出现裂缝的风险；分别浇筑形成下层后浇带和上层后浇带，防止一次浇筑成型中混凝土量少易被过分振捣导致混凝土发生离析现象，保证混凝土的结构强度，降低后期渗漏风险。
