一般穿过楼板的管道位于靠近墙壁或墙壁转角处,传统的管道周围支模是采用木板刻圆后支设,由于场地狭窄、支撑不便,易造成跑浆、混凝土密实性差,导致发生渗漏。通过实践,我们利用废胶管进行扎模施工,不仅节约了木材和用工,也杜绝了跑浆现象.改善了混凝土的密实程度。操作要点如下。1.采用定型模具(一般采用钢管,其内径应大于管道外径40～60mm)预留管道过板孔,在混凝土终凝前可取出。2.预留孔应符合管道设计位置,严禁事后剔 Generally, the pipe passing through the floor is located near the corner of the wall or wall. The traditional pipe around the support mold is carved after the wood is engraved. Because of the narrow site and inconvenient support, the slurry is easily run and the concrete has poor compaction, resulting in leakage. Through practice, we use the waste rubber hose for the construction of the die clamp, which not only saves wood and labor, but also eliminates the running slurry phenomenon and improves the compactness of the concrete. The operating points are as follows. 1. The use of shaping mold (usually using steel pipe, its internal diameter should be greater than the pipe diameter 40 ~ 60mm) reserved pipe over the plate hole, before the final setting of the concrete can be removed. 2. The reserved hole should meet the design position of the pipeline and it is strictly prohibited
