Pipe hole formwork-suspending device

The invention relates to a pipe hole formwork-suspending device which comprises a base plate. The base plate comprises at least two templates, wherein the templates can be spliced or separated, a pipe hole is formed in the base plate and comprises multiple arc-shaped portions, and the arc-shaped portions are arranged on the first side edges of the templates. The pipe hole formwork-suspending device further comprises first rubber strips, second rubber strips and rubber strings, wherein the first rubber strips are arranged on the first side edges, the second rubber strips are arranged on the upper planes of the templates, the templates are connected through the rubber strips, inlaying grooves are formed in the templates, and the rubber strings are inlayed in the inlaying grooves. The pipe hole formwork-suspending device is simple in structure and can be quickly mounted and dismounted, workers and the material usage amount are decreased, and other work progresses of other floors are not influenced. In addition, the pipe hole can be sealed when concrete is cast into the pipe hole, accordingly slurry leakage is prevented, the problems of water leakage and water seepage or even concrete loosening and shedding at a later stage are prevented, and pipe hole plugging can be well achieved.
