[Configuration of floor sleeve unit]
FIG. 1 is an explanatory view showing an embodiment of a floor sleeve according to the present invention, FIG. 1 (A) shows a front view, and FIG. 1 (B) shows an XX section thereof. FIG. 2 is an explanatory view showing a part of a floor sleeve provided with a fitting blade member.

  As shown in FIG. 1A, a floor sleeve 10 according to this embodiment includes a cylindrical sleeve body 12 through which a pipe is inserted, and a water-stop sleeve that is detachably provided on the upper portion of the sleeve body 12 by a fitting 20. 14.

  L-shaped positioning members 16 are fixed to three locations on the lower outer periphery of the sleeve body 12 by welding or the like. Further, fitting blade members 18 whose lower end portions are fixed by welding or the like are provided at six locations on the outer periphery of the lower end portion of the sleeve main body 12 that is below the positioning member 16.

(Mating blade member)
As shown in FIG. 1, the fitting blade member 18 fixes the lower part to the outer periphery of the lower end portion of the sleeve main body 12 and bends the upper side in a mountain shape so that the tip is pressed against the outer periphery of the sleeve main body 12. As shown in FIG. 2, the details of the fitting blade member 18 are obtained by bending a strip-like metal plate member made of, for example, stainless steel into a mountain shape having an apex angle of about 120 ° to 150 ° on the upper side. The lower part is fixed to the lower end of the sleeve main body 12 by welding or the like, and the upper end bent in a mountain shape is pressed against the outer peripheral surface of the sleeve main body 12.

  Here, when the outer shape of the sleeve main body 12 is 146 millimeters, for example, the height H1 from the sleeve lower end to the positioning member 16 is the depth of a sleeve placement hole provided in the concrete plate member described later, that is, the thickness of the concrete plate member. For example, H1 = about 100 millimeters. On the other hand, the height H2 of the fitting blade member 18 is lower than the depth H1 of the sleeve arrangement hole, for example, H2 = 45 millimeters.

  The width W1 of the fitting blade member 18 is about 15 millimeters, and the thickness of the metal plate member used for the fitting blade member 18 is about 0.5 millimeters. Further, the height h of the fitting plate member 18 from the outer peripheral surface of the sleeve is such that the inner diameter of the sleeve disposition hole provided in the concrete plate member is, for example, 150 mm, and the ring shape is 2 mm between the sleeve body 12. Since a gap is formed, the height h is larger than the gap, for example, about several millimeters.

(Water stop sleeve)
FIGS. 3A and 3B are explanatory views showing the water stop sleeve provided on the upper portion of the sleeve main body. FIG. 3A shows a plan view and FIG. 3B shows a front view.

  As shown in FIG. 3, the water stop sleeve 14 extends downward by fixing a fitting member 20 using a metal plate at four locations inside the cylindrical sleeve body 22 by welding or the like. As shown in FIG. 1, the fitting member 20 can be detachably fitted into the upper portion of the sleeve main body 12 as shown in FIG. 1.

  When the floor of the building is constructed by placing concrete with the floor sleeve 10 shown in FIG. 1 fitted in the sleeve placement hole of the concrete plate member, the water-stopping sleeve 14 is the water accumulated on the upper surface of the floor. The water stop sleeve 14 is removed when the pipe 12 is passed through the floor sleeve 10 so as not to flow down to the lower floor through the main body 12.

(Fixing and fixing of floor sleeve by mating blade member)
FIG. 4 is an explanatory view showing a state in which a floor sleeve is fitted and fixed to a concrete plate member and a state in which concrete is placed, FIG. 5 is an explanatory view showing a state in which the concrete has hardened and the water stop sleeve is removed, and FIG. It is explanatory drawing which showed the state of the insertion fixation of the floor sleeve by the fitting blade member with respect to the sleeve arrangement | positioning hole of a concrete board member.

  When the floor of the building is constructed, the floor sleeve 10 according to the present invention is first installed as shown in FIG. 4 (A). 24 is installed by temporary assembly, so that the portion of the sleeve body 12 of the floor sleeve 10 where the lower fitting blade member 18 is provided is pushed from above into the sleeve placement hole 26 of the concrete plate member 24. This pushing is performed until the positioning member 16 fixed to the outside of the sleeve body 12 hits the upper surface of the concrete plate member 24 and stops.

  Here, as shown in FIG. 2, the height H <b> 1 from the lower end of the sleeve to the positioning member 16 is the same as the thickness of the concrete plate member 24, so that the positioning member 16 hits the upper surface of the concrete plate member 24. Until the sleeve lower end is flush with the lower surface of the sleeve placement hole 26 in the concrete position member 24.

  As shown in FIG. 4A, when the mating blade member 18 on the lower side of the sleeve main body 12 is pushed into the sleeve arrangement hole 26 from the lower side of the floor sleeve 12, the sleeve arrangement hole 26 is obtained as shown in FIG. The angled portion of the fitting blade member 18 is squeezed into the gap between the sleeve body 12 and the sleeve main body 12, and the peak of the angled portion is the inner wall of the sleeve placement hole 26 due to the reaction force due to the spring property of the fitting blade member 18 Accordingly, the fitting blade member 18 is interposed at six positions with respect to the sleeve arrangement hole 26, so that it can be firmly supported and fixed.

  Here, the width of the ring-shaped gap formed between the sleeve arrangement hole 26 into which the fitting blade member 18 shown in FIG. In the case of millimeters, the inner diameter of the sleeve placement hole 26 is 150 millimeters, the width of the ring-shaped gap is 2 millimeters, and the height of the chevron of the fitting plate member 18 before pushing is, for example, 5 millimeters. When this is crushed to 2 millimeters by being pushed in, a strong reaction force is generated and strongly pressed against the inner wall of the sleeve arrangement hole 26, so that it can be firmly supported and fixed.

  Subsequently, as shown in FIG. 4B, concrete 28 is driven on the concrete plate member 24 to form a floor of the building. In this case, the concrete 28 is driven so that the concrete upper surface 28a is located at a predetermined position on the water stop sleeve 14 side beyond the boundary 15 where the sleeve main body 12 and the water stop sleeve 14 are combined.

  In the situation where the concrete 28 placed in this way is hardened, water may accumulate on the concrete upper surface 28a due to various on-site work, but the water stop sleeve 14 is fitted on the upper portion of the sleeve body 12 embedded in the concrete 28. Therefore, even if water accumulates on the concrete upper surface 28a, the water stop sleeve 14 prevents the sleeve main body 12 from flowing into the inside of the sleeve main body 12 and can reliably prevent water leakage to the lower floor.

  Subsequently, when the concrete 28 is hardened and fixed to the floor sleeve 10 through piping, the water stop sleeve 14 shown in FIG. 4 (B) is removed prior to this, and the main body sleeve shown in FIG. 5 (C) is removed. 12 is buried in the concrete 28, and in this state, the sleeve body 12 is supported and fixed through a pipe. Thus, since the water stop sleeve 14 can be removed, the operation | work which cut | disconnects the sleeve front-end | tip which protrudes from the concrete upper surface using electric tools, such as a sander, conventionally is unnecessary.

  Here, the water-stop sleeve 14 removed from the sleeve body 12 is used by being fitted to the tip of the sleeve main body 12 used in the construction of the ceiling of the next upper floor, and the water-stop sleeve 14 is used. By sharing the floor sleeve 10, the cost can be reduced.

[Variations of the present invention]
In the above embodiment, the water stop sleeve is detachably provided on the upper portion of the sleeve body, but a floor sleeve that does not use the water stop sleeve may be used.

  In the above-described embodiment, the fitting blade members 18 are provided at six locations on the outer periphery of the lower end of the sleeve main body 12. However, the fitting blade members 18 may be provided at least at three locations, and 3 as required. What is necessary is just to provide in several places more than a place.

  The present invention is not limited to the above-described embodiments, includes appropriate modifications without impairing the objects and advantages thereof, and is not limited by the numerical values shown in the above-described embodiments.
