Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof construction structure for a structure such as a building, and more particularly to a waterproof construction structure capable of accurately detecting the presence / absence of water leakage and the position of water leakage in the waterproof construction.

[0002]

2. Description of the Related Art In waterproofing construction of flat roofs of buildings, the biggest problem is to prevent water leakage due to deterioration of the waterproof layer over time. The same applies to pools, bathrooms, artificial ponds in buildings, etc.

When repairing these leaks, it is necessary to detect the presence or absence of leaks and the position of the leaks. However, once the leaked water circulates like a living creature and reaches the exit, it will reach the exit. It is not possible to accurately judge the entrance, and repairs are repeated depending on intuition and experience, and the waterproof layer is destroyed over a wide area, and large-scale re-construction work is being forced.

[0004]

[Means for Solving the Problems] The present invention is a waterproof construction structure for a building, which is capable of properly detecting the presence or absence of water leakage in the waterproof construction and the position thereof, and performing an appropriate subsequent repair. When a plurality of conductive lines are laid parallel or vertically and horizontally on a waterproof surface with a gap, a waterproof layer is applied to cover the conductive lines, and when water leaking through the waterproof layer short-circuits the conductive lines. The water leak detection circuit is configured to be closed.

As a means for forming the conductive line, a tape provided with a conductive layer over the length is prepared, and the tape is adhered to the waterproof construction surface to form the conductive line.

[0006]

[Function] When waterproofing is performed, the conductive line as described above is laid on the waterproof layer in advance as a water leak detecting means.
Water leakage that has permeated the waterproof layer can be immediately short-circuited between the conductive lines, the water leakage detection circuit can be closed, and externally displayed and notified.

That is, when the conductive lines are provided in parallel, it is possible to detect that water has leaked on the line where the conductive lines are laid due to the short circuit between the lines due to the water leakage.
When the conductive lines are laid vertically and horizontally, the short circuit between the horizontal and vertical lines at the intersection causes
It is possible to detect that water has leaked at the intersection, and the location of occurrence can be identified more accurately.

By the above, the presence and position of water leakage can be specified and an appropriate subsequent repair can be performed.

[0009]

The present invention can be applied to all waterproof construction parts such as flat roofs, bathrooms, pools, and ponds in buildings.

FIG. 1 shows a flat roof waterproof construction structure in which the present invention is applied to the roof of a building.

As shown in FIG. 2 or 3, a plurality of conductive lines are laid on the waterproof work surface 1 at intervals, and the conductive lines 2
The waterproof layer 3 is applied so as to cover the conductive line laying surface.

The waterproof construction surface 1 is a concrete slab 8 having a flat roof (rooftop). Or, it means a waterproof construction surface such as a veranda or a pouch. In the case of a concrete slab having a flat roof, the surface thereof is leveled with mortar, the conductive line 2 is laid on the surface, and the waterproof layer 3 covers the surface. Concrete is cast on the surface of the waterproof layer 3, or a concrete block or the like is laid down to form a finishing layer 9.

The waterproof layer 3 is applied waterproof or sheet waterproof, and can be exposed waterproof without covering the surface with the finishing layer 9 depending on the site.

As the conductive line 2, for example, a known flat cable tape can be used. For example, as shown in FIG. 4, this flat cable tape A is formed by adhering two conductive layers 5 on the surface of a water-impermeable insulating tape 4 forming a base over the length thereof and covering the conductive layer 5 with the above insulating material. It is a tape in which a water-permeable insulating tape 6 is layered on the tape 4, and the flat cable tape A is crossed in parallel or vertically and horizontally with the waterproof construction surface 1 as shown in FIGS. 2, 3 and 6 and 8. And a waterproof layer 3 covering the same is applied.

The flat cable tape A is laid on the waterproof construction surface 1 with an adhesive agent by using the tape 4 of the base thereof.

Alternatively, the flat cable tape A is a double-sided adhesive tape, and the base tape 4 is applied to the waterproof construction surface 1.
Laying with adhesive.

Alternatively, without using the flat cable tape A, as shown in FIG. 2, a conductive wire is laid on the waterproof surface to form the conductive line 2.

Similarly, the conductive layer 5 of the flat cable tape A can be made a bare wiring without being covered with the water permeable insulating tape 6.

Although not shown, the conductive layer 5 in the flat cable tape A may be a single strip. The point is a structure in which the conductive lines formed by the conductive layer 5 are short-circuited by water leakage.

When the flat cable tape A is provided with two conductive layers 5, short-circuit lines can be formed with the tape A as a unit.
By laying at intervals of m, the desired conductive line 2 can be easily laid.

As the laying mode using the flat cable tape, as shown in FIGS. 5 and 6, the tapes A are laid in parallel at predetermined intervals, or as shown in FIGS. 7 and 8. The tapes A ₁ and A ₂ are laid in a grid pattern so as to cross each other in the vertical and horizontal directions to form conductive lines 2a and 2b having a matrix structure that cross in the vertical and horizontal directions.

The flat cable tapes A ₁ and A ₂ have a non-water-permeable insulating tape 4 as a base, and when the tape 4 is assembled in a lattice shape as shown in FIGS. 7 and 8, the vertical and horizontal lines 2a, It serves as an insulating means between 2b and can be easily laid vertically and horizontally.

Further, the flat cable tapes A, A ₁ ,
When A ₂ is covered with the surface layer of the water-permeable insulating tape 6, the surface layer quickly permeates water leaking under the waterproof layer 3 to induce a short circuit between lines.

The present invention relates to the flat cable tape A,
As shown in FIG. 2, the conductive line 2 is used without using A ₁ and A ₂ .
Can be wired in parallel or crossed vertically and horizontally. In the case of vertical and horizontal cross wiring with bare wiring, some insulating spacer is interposed between the cross portions.

Thus, as shown in FIG. 6, when the conductive lines 2 are laid in parallel as the underlayer of the waterproof layer 3, the leakage of water through the flaws of the waterproof layer 3 immediately occurs between the lines under the waterproof layer. A short circuit occurs and the water leak detection circuit is closed. Each line 2 in FIG. 6 is a single line or a double line such as tape A.

When the circuit is closed, the lamp 10 on the external observation panel (display panel) 7 is turned on to notify the leak position.

That is, the conductive line 2 is provided with an address according to a predetermined order and is arranged so that, for example, when the line 2 at the address is short-circuited, the lamp 10 is turned on. As a result, the occurrence of water leakage on the ground of the conductive line 2, that is, the presence / absence of the water leakage and the position where the water leakage has occurred can be identified and can be detected on the observation board 7.

Further, as shown in FIG. 8, the conductive lines 2a, 2b
In the case of laying in a grid shape by crossing vertically and horizontally and lining with the waterproof layer 3, the leaked water 11 that has penetrated through the flaw portion of the waterproof layer 3 immediately under the waterproof layer 3 between the lines 2a and 2b, for example, the crossover. The lines 2a and 2b in the section are short-circuited to close the water leak detection circuit.

Similar to the above, the vertical line 2a is provided with addresses a to n, and the horizontal line 2b is provided with addresses a to n.
When the intersection of the line at the address and the line at the address c is short-circuited by the water leak 11, the lamp 10 and c of the lamp 10 are lighted correspondingly.

As a result, the occurrence of water leakage at the intersection of the track address and c, that is, the presence or absence of the water leakage and the position of the water leakage can be specified more accurately, and this can be known on the inspection board 7. Each of the lines 2a and 2b in FIG. 8 is a tape A.
It can be implemented as a double track or a single track.

1 to 8 teach the case where the conductive line 2 is laid as a base of a waterproof layer having a relatively large area such as an indoor pool or an indoor pond in addition to a flat roof.

On the other hand, FIG. 9 shows an embodiment in which the joint groove between the outer wall panels of the building or the joint groove at the portion where the bathtub and the inner wall are in contact is sealed.

In FIG. 9, 12 is an outer wall panel 13 of the building.
The above-mentioned joint groove formed between them, and the inside of the joint groove 12 is filled with the sealing material 14 corresponding to the waterproof layer.
The two conductive lines 2 are arranged in parallel on the back side of the sealing material 14. The back side of the conductive line 2 is filled with a backup material 15 made of foam resin or the like. That is, the conductive line 2 includes the sealing material 14 and its backup material 15
It is interposed between them.

In accordance with the above, various joint groove waterproof construction structures are formed. When the conductive line 2 is formed of the flat cable tape A, the base tape 4 exerts water-blocking property to surely induce a short circuit due to water leakage, and also complements the waterproof function of the sealing material 14. Will also be.

[0035]

According to the present invention, when water leaks through the waterproof layer, the conductive lines are immediately short-circuited and the water leak detection circuit is closed to perform illumination display with a lamp or the like. Presence / absence and location of occurrence can be accurately detected.

Based on this, it is possible to surely repair the waterproof flaw with minimum repair work by specifying the entrance of the leak and before the leak diverts to each part and is damaged immediately after the leak occurs. Can start repair work.
