BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water shut-off device for preventing water leakage from a floor through hole before a sealing work of this type during construction work of a building or the like.

[0002]

2. Description of the Related Art In general, in building construction, a skeleton construction is carried out sequentially from the first floor to the upper floor, and interior work is carried out from the lower floor in a form of chasing it.

By the way, in buildings such as buildings, it is necessary to lay pipes for drinking water or sewage or electric cables from the top floor to the first floor, and these pipes and electric cables are installed on the floor of each floor. A through hole is provided for passing through.

Since the sealing work for the through-holes on these floors must be carried out after the pipes and electric cables have been laid, from the order of the above construction, it is inevitable that it will be at the final stage when the construction work on all floors is completed. I have no choice.

However, as mentioned above, since the interior work is being performed in the downstairs in a form of chasing the frame work, upstairs,
In particular, if water leakage from the top floor is not prevented, inundation may cause unexpected damage to the interior construction work below.

For this reason, conventionally, provision was made to prevent water from entering the through holes in the floor of each floor until the last full-scale sealing work.

8 to 10 show conventional provisional measures for preventing water infiltration.

FIG. 8 shows a provisional water infiltration prevention measure for a floor slab with a floor penetration sleeve buried therein.

In the method shown in FIG. 8, the floor penetrating sleeve 20 is left inside the floor slab 21 until it is removed after the concrete is poured, and the tip portion of the floor penetrating sleeve 20 protruding from the floor surface is attached to the adhesive tape 22 or the like. It is a method of blocking by.

In the method of FIG. 9, after pouring concrete, the floor penetration sleeve is removed, a mortar bank 24 for preventing water inflow is provided so as to surround the penetration hole 23, and the opening of the penetration hole is covered with a veneer plate 25. It is a method of closing with etc.

In the method shown in FIG. 10, the floor penetrating sleeve is removed after the concrete is poured, the concrete flat plate 26 is placed on the through hole 23, and the peripheral edge of the concrete flat plate 26 is sealed by the sealing material 27. Is the way.

[0012]

However, in the water-stopping measures shown in FIG. 8, the opening of the floor-penetrating sleeve is simply closed with the adhesive tape, so that when a heavy object is placed on the adhesive tape, Could be damaged.

In some cases, it may be necessary to remove the adhesive tape for the purpose of marking out the work, but after the adhesive tape was removed, water could not be prevented. Furthermore, since the tip of the sleeve projects from the floor, it is inconvenient for workers to pass through.

In the method shown in FIG. 9, since a mortar bank must be purposely provided around the floor through-hole, the construction work for this purpose is significantly increased in a building having a large number of floor through-holes. In addition, it was not possible to expect complete water shut off because the plywood was simply placed on the floor through hole.

In the method of FIG. 10, the concrete slab may be damaged when removed, and is not suitable for repeated use. In addition, preparing a large number of concrete flat plates was inconvenient for storage and management.

[0016] As described above, the conventional water stop measures for floor through holes have problems that water cannot be completely stopped, it is unfavorable for safety, and the number of construction members to be discarded after only one use is increased.

Therefore, the problem to be solved by the present invention is to solve the problem of the above-mentioned provisional water stop measures for floor through holes, which can be standardized as a construction material, and which can safely and surely stop water.
