［実施例Ｊ
以下、本発明の一実施例について図面を参照しながら説
明する。[Embodiment J] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
ｆ５１図において、１はスラブ用型枠であって、その貫
通孔位置にスリーブ２をセットする。In Figure f51, 1 is a formwork for slabs, and the sleeve 2 is set in the through hole position.
該スリーブ２は、第２図からも明らかなように、円筒状

ようにするとよい。The sleeve main body 2a is made of a plastic or metal cylinder, and a pipe P (see Fig. 4) passes through the sleeve body 2a.
has an inner diameter larger than the diameter of the slab and a height slightly lower than the slab thickness. Further, when the sleeve main body 2a is to be removed after slab concrete is placed, it is preferably formed into an upwardly tapered shape (imaginary line shape 1 in Figure #S2) so that it can be easily pulled out.
上記キャップ２ｂは、スリーブ本体２ａに対して着脱自
在に嵌め込まれている。この場合、この去め込み部から
水が浸透しないように、水返し２ｂ。The cap 2b is removably fitted into the sleeve body 2a. In this case, the water return 2b is installed to prevent water from penetrating through this recessed portion.

Make a notch 2b at an appropriate location on the back side of the outer periphery of the cap 2b, and insert the tip of a screwdriver etc. into the notch 2b to remove the cap 2b.
It is a good idea to make it easy to remove.
上記固定釘２ｃは、少なくとも３個以上、スリーブ本体
２ａの円周下端部に均等に配置しておくのが望ましく、
該固定釘２ｃをスラブ用型枠１に打付けてスリーブ２を
セットする。It is desirable that at least three or more fixing nails 2c are arranged evenly around the lower end of the circumference of the sleeve main body 2a,
The sleeve 2 is set by driving the fixing nails 2c into the slab formwork 1.

の位置に分離して配置してもよい。The spacer 2d maintains a slight gap S between the slab formwork 1 and the lower end surface of the sleeve body 2a, and the sleeve 2d
This is done so that the mortar of the poured concrete slab can flow into it. In this embodiment, the spacer 2d also serves as a support for the fixing nail 2c. These fixed nails 2c and spacers 2d may be arranged separately at different positions.
上記スリーブ２のセットが完了すると、ｆｊＳ３図に示
すように、スラブコンクリートＣを打設する。When the setting of the sleeve 2 is completed, slab concrete C is poured as shown in Fig. fjS3.
この時、上述のようにスラブ用型枠１とスリーブ本体２

ている。At this time, as mentioned above, the slab formwork 1 and the sleeve body 2
Mortar flows from the gap S between the lower end surface of a and integrates with the concrete that will be poured later into the sleeve 2.
In addition, especially in the case of an implantable sleeve, sleeve 2
Sufficient cover thickness is provided to prevent the lower end surface from being exposed from the lower surface of the slab and causing fire resistance problems.
コンクリ−）Ｃが硬化したら、上記スラブ型枠１を脱型

にしてもよい。In addition, in place of the above-mentioned formwork 3 for concrete post-casting around the pipe, a split-type formwork 4 for post-casting concrete around the pipe as shown in Fig. 7 is used to tighten the pipe body P with a tightening band 4a. At the same time, bolts may be passed through the holes of the 7-run no. 4b and tightened to attach them to the pipe P, and post-cast concrete C' may be placed in the gap between the sleeve 2 and the pipe P, as shown in Figure Pt5a. In this case, for the implanted sleeve 2?
It has a sufficient thickness and is particularly effective in fire resistance. Therefore, when pouring the mortar under the sleeve 2 when pouring the slab concrete (C), it is not necessarily necessary. For fastening with the above-mentioned tightening band 4a, in addition to using bolts and nuts as shown in the figure, a fastening metal fitting that can be latched with one touch may be used.
