As shown in figure 1 and figure 2, the utility model provides a concrete floor reserves hole device, the device include obturator 1, and obturator 1 includes bottom plate 11 to and the barrel 12 of winding bottom plate 11 periphery setting. Alternatively, in this embodiment, the cylinder 12 and the bottom plate 11 are integrally formed, and in other embodiments, the cylinder 12 and the bottom plate 11 may be adhesively connected. The cross section of the bottom plate 11 is circular in outer contour; the cylinder 12 includes a first plate 121 and a second plate 122, one end of the first plate 121 is connected to the bottom plate 11, and the other end of the first plate 121 is connected to the second plate 122. The outer diameter of the first plate body 121 gradually increases, and the outer diameter of the end of the first plate body 121 connected to the second plate body 122 is larger than the outer diameter of the end of the first plate body 121 connected to the bottom plate 11; the second plate 122 is cylindrical. On one hand, the structure can facilitate the device to be taken out of the reserved hole after the reserved hole is formed; on the other hand, after all pipelines are installed, the reserved holes of the floor slab need to be plugged. The traditional method is that the periphery of a reserved hole to be sealed is kicked and roughened to form a cone or a bowl, so that the subsequent concrete pouring is facilitated, and the water seepage condition after the plugging is finished can be prevented; and then pouring concrete into the reserved hole for plugging. This embodiment the device has reduced the artifical work load of playing, chiseling the preformed hole of beating, can effectively promote the efficiency of construction, and fashioned preformed hole is of high quality, can further prevent the condition that the infiltration appears after the shutoff. In addition, in the floor slab pouring process, compare in the condition that the cross section outline of barrel 12 sets up to the polygon, the cross section outline of barrel 12 sets up to circular in this embodiment for barrel 12 week portion is whole to be pressed evenly, avoids barrel 12 to warp at the pouring in-process, and then influences the quality of reserving the hole.

Optionally, the outer surface of the first plate 121 is a spherical surface. In other embodiments, the outer surface of the first plate 121 may be provided as a tapered surface.

Further, the second plate 122 is at least partially located outside the concrete floor 9 at the reserved hole, so that the concrete can be prevented from pouring the whole reserved hole device into the floor in the process of pouring the floor.
