つた。(Prior art and problems to be solved) Conventionally, as a construction method for making through holes for wiring in a concrete floor, as shown in Figures 3a to 3d, first, a paper-based cylindrical body (void)
After the concrete has hardened, remove the void together with the formwork to form a through hole, and insert electric wires etc. into it for wiring.b
After that, the iron plate was fixed to the underside of the floor with anchors, Figure c, and the gap between the through hole and the wire was filled with glass wool, etc., and the wire was fixed in Figure D. However, such a construction method is not only extremely cumbersome, but also has the risk of damaging the electric wire at the edge of the through hole during wiring.

ることが好ましい。 More specifically, the through-hole forming sleeve according to the present invention is made by flat winding, spiral winding, etc. a metal plate such as a steel plate, galvanized steel plate, or stainless steel plate with a thickness of 0.4 to 2.0 mm to a diameter of 50 to 300 mm. A metal cylindrical body 1 is formed. The shape of the cylindrical body may be any shape such as circular, elliptical, or angular in cross section. Therefore, the protruding ring band 2 provided on a part of the side wall of this metal cylindrical body protrudes in the inner diameter direction with a width of 2 to 10 mm and a height of 2 to 10 mm, and is formed in a continuous or dotted line shape. . Furthermore, the lower end of the through-hole forming sleeve of the present invention is bent outward with a radius 4, and
It is preferable that the lid 3 is fitted into the upper end if necessary.

する（ｃ図）。 The construction method used for the through-hole forming sleeve of the present invention is shown in FIGS. 2a to 2c. That is, the sleeve according to the present invention is attached to the formwork 5, concrete is poured to form the floor (Figure a), and then the sleeve is removed and the wiring is performed as shown in Figure B. Then, the drop cover 6 is inserted and the sleeve is removed. The gap between the wire 7 and the electric wire 7 is filled with glass wool 8, etc. (Figure c).

る。(Effects) As mentioned above, the through-hole forming sleeve according to the present invention is made of a metal plate such as a steel plate, a zinc-gained lead plate, or stainless steel, so there is no need to remove it after pouring concrete as in the conventional case. In addition, the protruding ring band that protrudes in the inner diameter direction serves as a stop for the drop-in lid and acts as an inner rib to prevent deformation.Furthermore, the lower end of the sleeve is curved and bent, making it easy to use when wiring. It does not damage the electric wire, and if a lid is provided at the upper end, the lid, which is fitted into the through hole when not in use, has the effect of preventing the sleeve from deforming.
