PPR combined mold used for floor slab reserved hole construction
The invention relates to a PPR combined mold used for floor slab reserved hole construction. The PPR combined mold comprises three parts including a circular platform barrel body, a circular cover plate and a special bolt, wherein round holes which are two times as large as the diameter of the bolt and have the same size are formed in the bottom center of the circular platform barrel body and the center of the circular cover plate respectively. When the combined mold is mounted, the position of a reserved hole is found on a mounted horizontal template according to design requirements of a construction drawing, and a cross-shaped intersecting line is released; secondly, a handholding electric drill is used for drilling a hole which is two times smaller than the diameter of a fixed bolt of the combined mold on a cross-shaped intersecting point; finally, the special bolt penetrates through the cover plate and the circular platform barrel body, and the special bolt is aligned with the drilled hole and is downwards screwed up and fixed on the template by a wrench. The PPR combined mold is easy to detach and mount; the quality common failing that the position of the pipeline reserved hole is not accurate is avoided and the construction progress is accelerated; the construction quality is improved; bad phenomena that the position is chiseled inaccurately in a mounting process and the structure is damaged by chiseling and the like are overcome.
