Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water leak detector suitable for high-rise apartment houses such as condominiums.

[0002]

2. Description of the Related Art Generally, in an apartment house of this type, a water supply / drainage pipe for a kitchen or a bathroom or a water supply / drainage pipe for a washing machine is an underfloor space portion provided between a concrete slab partitioning from a lower floor and a floor. It is used for piping. Therefore, it is extremely difficult for residents to directly and early detect water leaks from the water supply / drainage pipes that occur in the space under the floor. The system to discover was adopted. In particular, for water supply or hot water supply pipes, water leaks because the frequency of use is high and the pressure inside the pipes is high, and because chlorine-based bactericide is added, corrosion at the joint part is particularly likely to proceed. There were many accidents. Also, even if a leak was detected, if it could not be dealt with promptly, the water would continue to leak, and further, the worst situation such as a leak to the lower floor would occur.

[0003]

However, since the conventional electric type water leakage detection system is a centralized monitoring system for controlling the water leakage sensor etc. at one place, the electric work and the wiring work are very large and costly. It was high. In addition, this system only detects leaks, and it is not possible to take measures such as emergency draining of leaked water in place, so there is still a problem that water leakage continues until the leak point is repaired. was there. For this reason, the leak detection system is not widely used in general housing such as condominiums. Therefore, an object of the present invention is to provide and popularize a simple and reliable leak detector that enables early detection and emergency drainage of leaks in an apartment house such as a high-rise condominium.

[0004]

Therefore, according to the invention of claim 1, the water collecting member provided on the upper surface of the concrete slab that divides the upper floor and the lower floor, and the outdoor connected to the water collecting member. And an upper water guiding pipe having an opening, the upper surface of the concrete slab is formed so as to collect water toward the water collecting member in response to leakage of water generated in the upper floor, and the water guiding pipe is exposed to the outside of the eye. It is characterized by opening at an easy position.

[0005]

According to the structure of claim 1, the leaked water under the floor flows on the upper surface of the concrete slab and is collected by the water collecting member.
After that, it is drained by a water conduit to a location that is easily visible outside the room. Therefore, it is difficult for a resident to directly detect the leak under the floor, but the drainage from the water conduit can be easily confirmed, and thus the leak under the floor can be indirectly detected. Further, since the leaked water is drained to the outside of the room through the water conduit, this water conduit functions as an emergency drain port, and thus the worst case of water leakage to the lower floor is avoided.

[0006]

Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 shows a water leakage detector (hereinafter, simply referred to as “detector”) 1 of this example in a disassembled state.
As shown in FIG. 2, the upper floor U and the lower floor D are partitioned by the concrete slab 20, and a necessary water supply / drain pipe is provided in the underfloor space 30 between the floor F on the upper floor U side and the concrete slab 20. Or electrical wiring is installed. In this example, water leakage from the water supply pipe P of the kitchen K is taken up as illustrated.

As shown in FIG. 1, the detector 1 of this embodiment collects the water collecting member 2 for collecting the water leaked on the concrete slab 20 and the leaked water collected by the water collecting member 2. It is provided with a water conduit 3 for guiding the water to the outside of the room and draining it in a state where it can be seen by a person.

The water collecting member 2 is mainly composed of a saucer-shaped water collecting funnel 4 and a positioning fixture 5 for fixing the water collecting funnel 4 to a form at the time of concrete pouring. It is installed in the vicinity of the water supply pipe P for kitchen with the water collecting funnel 4 embedded in 20 and opened upward.

A notch 4a is formed around the opening of the water collecting funnel 4.
~ 4a is formed at an appropriate number of locations (four locations in the figure),
Water collecting channels 20a to 20a are formed on the upper surface of the concrete slab 20 so as to correspond to the respective cutouts 4a. The leaked water on the concrete slab 20 is collected in this water collecting channel 20a.
It flows into the water collecting funnel 4 via. Also,
A mesh-shaped strainer 6 is attached to the opening of the water collecting funnel 4 so as to cover it (see FIG. 2).

Further, a screw hole is formed in the central raised portion of the water collecting funnel 4, and the screw portion of the positioning fixture 5 is tightened in this screw hole.
The positioning fixture 5 is fixed to the formwork to position the water collecting funnel 4 prior to pouring concrete, which will be described later. The strainer 6 described above is attached using the wing nut 5b of the positioning fixture 5.

A drain port 4b is formed at the bottom of the water collecting funnel 4, and one end of the water guiding pipe 3 is connected to the drain port 4b via a nipple 7. The water conduit 3 is a flexible pipe, which is routed in the concrete slab 20 along a predetermined path, and the other end side is opened to the wall surface facing the outside of the room. A bushing 8 for fixing the form is attached to the other end of the water conduit 3 via a nipple 9, and further, a strainer 10, a short pipe 11a and a decorative plate 1 are attached.
1 is attached.

Next, the procedure for mounting the detector 1 described above will be described with reference to FIGS. 3 to 12. First, as shown in FIG. 3, the positioning fixture 5 is fixed by nailing or the like to a predetermined position of the formwork 21 framed prior to concrete pouring. Next, as shown in FIG. 4, the water collecting funnel 4 is tightened into the screw portion 5a of the positioning fixture 5 to position the water collecting funnel 4 at a predetermined height. At this time, as shown in FIG. 5, the height h of the water collecting funnel 4 from the mold 21 is matched with the slab thickness, and the opening of the water collecting funnel 4 becomes substantially flush with the upper surface of the concrete slab 20. To make adjustments.
Further, the drainage port 4b of the water collecting funnel 4 is oriented in the drainage direction. Furthermore, the opening of the water collecting funnel 4 is covered with the strainer 6 with the curing seal, and is fixed with the wing nut 5b.

After the water collecting funnel 4 is positioned and fixed to the form 21 in this manner, then, as shown in FIG. 6, the water collecting funnel 4 is guided to the drain port 4b through the nipple 7. One end of the water pipe 3 is connected. A seal tape 12 is wound around the nipple 7.

Next, as shown in FIG. 7, joint bars 13 to 13 for forming the water collecting passage 20a are arranged in accordance with the notches 4a to 4a of the water collecting funnel 4. Each joint bar 13
Bind it so that it will not move when pouring concrete.

On the other hand, a bushing 8 for fixing the mold is attached to the other end of the water conduit 3 via a nipple 9, and the bushing 8 is nailed and fixed to a predetermined position of the mold 22 on the outdoor side. deep. As described above, the water collecting funnel 4 and the water conduit 3
After fixing the other end of the to the specified position, concrete is poured. This state is shown in FIG.

When the concrete has solidified after a sufficient time has passed, the molds 21 and 22 and the joint bars 13 to 13 are removed as shown in FIG. After the formwork is removed, finishing work on the outer wall is done, and if this is completed,
As shown in FIG. 11, a strainer 10, a short pipe 11 a and a decorative plate 11 are attached to the other end of the water conduit 3.
In this state, the other end of the water conduit 3 is open to the outside through the short pipe 11a. This water conduit 3
The portion where the opening is formed is a position where a person can easily see it, specifically, a veranda or a wall surface on the passage side. Further, the curing seal is removed from the strainer 6 attached to the water collecting funnel 4 as shown in FIG.

As described above, the installation work of the detector 1 of this example is completed, and thereafter the interior work such as flooring is performed as usual.
The order of the interior work and the outer wall work is arbitrary according to various circumstances. In any case, the interior work is performed with joint bars 13 to 1.
3 is removed and the curing seal is removed from the strainer 6, and the decorative plate 1 is attached to the other end of the water conduit 3.
The work of attaching 1 is performed after the outer wall construction is completed.

As described above, according to the detector 1 of this embodiment, when water leaks from the water supply pipe P in the underfloor space portion 30 where the occupants cannot see, the leaked water first flows down on the concrete slab 20. It flows into the water collection channel 20a,
After that, water is collected in the water collecting funnel 4. The leaked water collected in the water collecting funnel 4 flows into the water guiding pipe 3 as it is, and is guided to a place on the outdoor side where a person can easily see it and is drained from the opening. Then, a person visually confirms the leakage of water drained from the opening of the water conduit 3 to confirm the leakage of water under the floor.

As described above, according to the detector 1 of the present embodiment, it is possible to easily detect the leakage of water under the floor simply by installing the water collecting funnel 4 and the water guiding pipe 3, so that the conventional scale is large. Therefore, it is possible to easily and surely detect water leakage without using a costly system, and thus the water leakage detector 1 can be widely used in apartment houses and the like.

Further, the conventional water leakage detector (leakage detection system) merely detects the water leakage and does not take a more positive measure against the water leakage. Therefore, if water leakage is detected but appropriate measures are delayed, or if it is left without any repairs, the water will gradually penetrate into the concrete slab over time, and eventually leak to the lower floor. This will cause serious trouble. In this respect, according to the detector 1 of the present example, the leakage of water under the floor is immediately discharged to the outside of the room, so that not only can the leakage be quickly detected, but also the situation of leakage to the lower floor can be avoided. .

The detector 1 described above is provided with the water conduit 3
Although the structure is such that a person visually recognizes the occurrence of water leakage by draining the water leakage led to the outside by means of, for example, a conventionally used water leakage sensor is attached in the middle of the water conduit 3 of each door, It is also possible to manage the signal generated by the water leakage sensor at one location and have a centralized water leakage monitoring function.

[0022]

As described above, according to the present invention, since it is possible to detect water leakage under the floor easily and reliably, the water leakage detector can be widely used in apartment houses such as high-rise apartments. Further, since the leak is drained to the outside of the room to detect the leak under the floor, not only the leak can be detected, but also a serious trouble such as leak to the lower floor can be avoided in advance.
