The present invention relates to a one-piece mold integrated with a manhole. More specifically, the one-piece mold, which is integrated with a manhole, enables the external and internal molds to be easily assembled and stripped. The mold according to an embodiment of the present invention includes: a horizontal support which has an elevating hole formed on the center; multiple external molds arranged edge of the support in the vertical direction; an internal mold which has side walls closely integrated to the ceiling lower than the upper end of the external mold while being spaced apart from the external mold and includes an outward flange on the lower part of the side walls to be placed near the lower part of the elevating hole of the support; and a rotating rod which has the lower part supported by the support to move in an idle rotation motion and has the upper end passing though the ceiling of the internal mold to be exposed to the outside while partially coupled with the internal mold in a spiral form. The structure enables the upright external mold to be hung by a latch and rotates the rotating rod to elevate the internal mold to complete the assembly of the mold. Accordingly, the present invention can easily form the mold and release the latch after curing concrete to fold the external mold and rotate the rotating rod to lift down the internal mold to quickly and easily strip off the mold. |
