Such a paper tube is used by cutting out a tube body that matches the thickness of the concrete-filled space to be cast from a long paper tube and fixing the tube body at the position where a through hole should be formed. After the concrete was poured into the concrete-filled space and set and hardened, the tubular body was peeled and removed from the formed through-hole.

た。According to the above-mentioned conventional floor through-hole forming tool, when the concrete is hardened and then peeled and removed from the formed through-hole, the shape is largely changed, and It has been pointed out that it is uneconomical because it becomes a non-reusable state and becomes disposable, and it has been desired to make the structure reusable to reduce costs. Further, since the tubular body is a cylindrical shape obtained by simply cutting out a long paper tube, the through hole is usually inserted through a pipe or the like, and then the inserted pipe or the like, and a through hole. Although the mortar is filled in the gap between the inner wall surface and the mortar, a holding means for holding the mortar in the gap is required to fill the gap. There is also a problem that it takes time and effort to replenish the work after forming the ridge, and a separate member is required as the holding means, resulting in a high cost.

用効果は以下の通りである。To achieve this object, the floor through-hole forming tool of the present invention is characterized by a through-hole forming cylinder member for arranging in a concrete filling space, and the through-hole forming cylinder. A tubular bottom edge forming member for forming a bottom edge projecting to the inside of the through hole is provided on one end side of the member, and the through hole forming tubular member and the bottom edge forming member are provided. Both are molded from a flexible elastic material, and in forming the bottom edge forming member, a fitting connecting portion that can be fitted into one end opening of the through hole forming tubular member is provided on one end side,
From the inside of the through-hole forming tubular member, a nailing part capable of nailing and fixing to a formwork panel in the concrete filling space is provided on the other end side, and between the nailing part and the fitting connection part, The other end side is formed to have a smaller diameter than the one end side,
A step forming portion is formed between the nail driving portion and the fitting connecting portion, and a lid forming member that closes the other end opening portion of the tubular member can be freely attached to and detached from the other end opening portion. It is preferable that the spring hardness Hs (JIS A) of the cylindrical member and the bottom surface forming member is 50 ° to 90 °.
It is even better if it is formed from a ° elastomer. The effects are as follows.

に対応しやすい。[Operation / Effect] That is, since the floor through-hole forming tool is configured by providing the through-hole forming cylinder member and the bottom edge forming member, the formed through-hole projects inward. Since the bottom edge portion is formed, it is easy to close the gap between the through hole and the pipe or the like arranged in the through hole using the bottom edge portion. That is, in forming the bottom edge forming member, a fitting connecting portion that can be fitted into the one end opening of the through hole forming cylinder member is provided on one end side, and from the inside of the through hole forming cylinder member, A nailing part capable of nailing and fixing to a formwork panel in a concrete-filled space is provided on the other end side, and the other end side is smaller in diameter than the one end side between the nailing part and the fitting connection part. Since the stepped portion is formed between the nail striking portion and the fitting connection portion, a bottom edge portion is formed by the stepped portion in the formed through hole, For example, the bottom edge portion can be used as a pedestal for arranging a bottom plate material that receives the filling material when filling the clearance with the pipe or the like arranged in the through hole. Further, since both the through hole forming cylinder member and the bottom edge forming member are molded from a flexible elastic material, after the through hole is molded and constructed, the both members are removed from the inside of the through hole. At the time of removal, if each member is bent and peeled from the inside of the through hole, it can be easily peeled. Further, both the peeled members can be reused because they can be returned to the original shape after the peeling only by elastically deforming. At this time, the tubular member can be easily deformed flexibly if the side wall is molded into a simple tubular shape, and a tubular member having a high versatility can be cut out to form the tubular member. Easily adaptable to the thickness of concrete to be poured.

It is possible to prevent the inconvenience that concrete material enters into the tubular member at the time of placing the concrete, and to cast the concrete slightly thicker than the height at which the tubular member and the bottom edge forming member are fitted. Even if it does, it is easy to form the through hole.

If it is too soft, it will bend and deform due to the inflow pressure of concrete when pouring concrete, and the dimensional accuracy of the through hole will be low.If it is too hard, it will be difficult to remove it from the through hole due to bending deformation after concrete pouring From the viewpoint, the spring hardness Hs (JIS A) is 50 ° to 90.
It is desirable that it be formed from an elastomer of °.
