Description

[Technical field]

[0001] The present invention relates to a technique for identifying the location of rainwater intrusion in a rainwater leak inspection for a building, and more particularly to a rainwater leak inspection tool and method for identifying the location of rainwater intrusion by dividing the rooftop or the like of a building and using a different colored test liquid for each division. [Background technology]

[0002] Conventionally, in investigating rain leaks in buildings, in order to identify the point of rainwater intrusion, a rain leak inspection method is known in which the area where rainwater is suspected to have intruded is surrounded by a partition, and a test liquid is sprayed or stored inside the partition, causing the test liquid to infiltrate the rainwater intrusion point within the section (see, for example, Patent Document 1 or Patent Document 2).

[0003] For example, Patent Document 1 discloses a water leakage inspection method in which an area suspected of leak penetration, such as the rooftop of a concrete building, is divided into multiple sections, and a different inspection liquid from the three primary colors of red, blue, and yellow is sprayed on each section to identify the location of the leak penetration. In the water leakage inspection method of Patent Document 1, the boundaries of the sections are blocked off with partitions to prevent the colored inspection liquids sprayed on each section from mixing.

[0004] Patent Document 2 discloses a method for inspecting for rainwater leaks in which cracks in a floor surface are surrounded by a wall made of clay material and a test liquid is stored inside the clay wall. In the method for inspecting for rainwater leaks in Patent Document 2, the test liquid is stored inside the clay wall, and water pressure is applied to the cracks in the wall, encouraging the infiltration of rainwater.

[0006] However, while the water leak inspection method in Patent Document 1 has the advantage of being able to inspect a wide area thoroughly by dividing it into sections, rather than inspecting specific locations as in the rain leak inspection method in Patent Document 2, it has the problem that the inspection liquid does not penetrate into thin cracks that are invisible to the naked eye, because it only involves spraying water.If the inspection liquid were to be stored in a section as in Patent Document 2, the water stop would fall over because the water stop is set up on a seal that only has enough adhesive strength to be peeled off. Furthermore, when inspecting for rainwater intrusion through small, invisible cracks or peeling parts of waterproof sheets, it is necessary to inspect a wide area through which rainwater may infiltrate. However, the leak inspection method of Patent Document 2 has the problem that it is costly in materials and time-consuming to enclose a wide area using clay walls. The present invention has been made in consideration of the above problems, and aims to provide a rain leak inspection tool and a rain leak inspection method that are inexpensive and easy to install, and that can identify with a high probability the location of rainwater intrusion through a thin crack.

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiment, and can be modified as appropriate without departing from the gist of the present invention.

[0017] (Leak inspection equipment) 1 shows how a rain leak inspection is performed on the roof of a building using a rain leak inspection tool 100 according to the first embodiment of the present invention. The rain leak inspection tool 100 mainly comprises a plurality of waterstops 1, ... and a waterstop material 2 that seals the joints between the waterstops 1, 1 and the joints between the waterstops 1 and an inspection target surface A on which the waterstops 1 are placed, such as the floor surface of a building roof.

[0018] In addition, the rain leak inspection tool 100 includes a balloon 3 used when inspecting for rain leaks around the drain outlet B, an air hose 4 for introducing air into the balloon 3, a manual air pump (air delivery means) 5 for delivering air to the balloon 3 via the air hose 4, and a masker 8.

[0019] The waterstop 1 is formed by cutting and processing a plate material such as a concrete panel or a plywood board, and includes multiple types (four types, reference numbers 11, 12, 13, and 14, in the illustrated example) of the same width but different lengths, as shown in Figures 2 and 5. Note that reference number 1 is used to collectively refer to the multiple types of waterstops, and reference numbers 11, 12, 13, and 14 are used to refer to individual waterstops, as described below.

[0020] The waterstops 11 and 12 shown in FIG. 2 are used to assemble a lattice (rectangular frame) 91 or lattice 92 (see FIG. 3 and FIG. 4) surrounding the drain outlet B. The waterstops 11 and 12 have a pair of cutouts 7, 7 cut in opposite directions from the long sides 11b and 12b in the short side direction near the short sides 11a and 12a. The cutouts 7 have a width approximately equal to the thickness of the waterstop 1 and are provided at half the length of the short sides 11a and 12a. The lattice 91 and 92 are formed by alternately connecting four waterstops 11 or two waterstops 11 and two waterstops 12 by fitting the cutouts 7, as shown in FIG. 3 and FIG. 4. The lattice 91, 92, ... are also collectively referred to by the reference symbol 9. In one example, waterstop 11 is approximately 36 cm long, waterstop 12 is 42 cm long, and both waterstops 11 and 12 are 18 cm wide.

[0021] The waterstop 1 of this embodiment further includes waterstops 13, 14 shown in Fig. 5. The waterstop 13, for example, is 18 cm wide and 42 cm long, and includes only one cutout 7 that cuts in from one long side 13b near one short side 13a. The waterstop 14, for example, is 18 cm wide and approximately 200 cm long, and includes two cutouts 7, 7 that cut in the same direction in the width direction from the long side 14b at positions slightly spaced from both short sides 14a, 14a.

[0022] Fig. 6 shows a partition member 10 formed by fitting two waterstops 13, 13 and one waterstop 14 together at their respective notches 7, 7. The partition member 10 is configured such that the waterstop 13 prevents the waterstop 14 from tilting. As shown in Fig. 1, by arranging a plurality of partition members 10, ... along the boundaries of compartments, compartments of various sizes and shapes can be partitioned with the waterstops 14.

[0023] 7 shows a crisscross structure 93 in which four waterstops 14 are assembled by fitting together their respective cutouts 7. In this way, the cutouts 7 of the waterstops 14 can also be used to connect them together.

[0024] The type of waterstop material 2 is not particularly limited as long as it can prevent the test liquid from leaking from the joint by applying or sticking it to the joint between waterstops 1 or between the waterstop 1 and the surface to be inspected A, and examples of the waterstop material include putty, caulking material, waterproof tape, masking material, adhesive, peel-off seal, etc. Fig. 8 shows an example in which putty is used as the waterproof material and applied in a fillet shape to prevent water leakage from the joint between the waterstops 1 and the waterstop 1, or at the point where the waterstop 1 touches the surface to be inspected A. As the putty, for example, a putty material made of oil clay or the like used to fill holes in walls for air conditioner hoses can be suitably used, but there is no limitation thereto, and any known putty material can be used as appropriate as long as it is poorly water-soluble. Caulking materials are fillers that fill gaps in objects, and examples of caulking materials include acrylic resins, polyurethanes, silicones, modified silicones, polysulfides, and the like. The waterproof tape is not particularly limited as long as it has waterproof properties and can be adhered to concrete, asphalt, etc., and may be a sheet-shaped substrate made of a rubber-based material or a synthetic resin-based material coated with an adhesive. Examples of rubber-based materials include butyl rubber and silicone rubber, and examples of synthetic resin-based materials include polyethylene and EVA (ethylene-vinyl acetate copolymer resin). A masker is a tape-like object that includes a foldable sheet material that extends from one end in the width direction of an adhesive tape made of cloth or the like. The peelable seal is a peelable caulking material, and for example, Hakuriseal ONE manufactured by Konishi Co., Ltd. can be used.

[0025] The balloon 3 is a hollow ball made of soft resin such as natural rubber or artificial rubber, and is configured to be inflated by air sent from a manual air pump (air sending means) 5 (not shown) through a resin air hose 4. As shown in Fig. 9, when a rack 92 is provided to surround the drain outlet B and the rack 92 is filled with the test liquid L, the balloon 3 is inflated inside the drain outlet B to prevent the test liquid from flowing into the drain outlet B.

[0026] Fig. 11 shows a state in which the waterstop 1 is covered with a masker 8. In the example of Fig. 11, an adhesive tape 81 of the masker 8 is attached to the upper surface of the waterproof tape 6 that has been applied to the inspection target surface A along the waterstop 1, and the waterstop 1 is covered with a sheet portion 82 that extends from the adhesive tape 81 in the width direction.

[0027] (How to check for leaks) Next, a rain leak inspection method for identifying the location where rainwater enters using the rain leak inspection tool 100 according to this embodiment will be described.

[0028] (Compartment formation process S1) The compartment formation step S1 is a step of compartmentalizing an area where rainwater intrusion is suspected by using a plurality of waterstops 1. A plurality of compartments can be provided, and a test liquid containing a fluorescent agent of a different color is stored in each compartment in the test liquid storage step S5 described later. In the compartment formation step S1, the cutouts 7 of the plurality of waterstops 1 are fitted together to form a grid 9 or a partition member 10, which surrounds each compartment.

[0029] Fig. 1 shows an example in which the inspection target surface A includes a drain outlet B and a so-called pigeon coop C. In the example of Fig. 1, the entire inspection target surface A is surrounded by a number of partition members 10, ..., the drain outlet B is surrounded by a lattice 92, and the pigeon coop C is surrounded by a lattice 93, dividing the inspection target surface A into a section Y including the drain outlet B, a section Z including the pigeon coop C, and a section X excluding sections Y and Z of the inspection target surface A. The lattice 92 surrounding the drain outlet B is contained in a rectangular recess A3 that guides drainage to the drain outlet B.

[0030] (Water stop process S2) The water-stopping process S2 is a process for sealing water between the waterstop plates 1 of the lattice 9 and the partition member 10 assembled in the compartment forming process S1, and at the joints between the waterstop plate 14 and the surface A to be inspected, using a water-stopping material 2. As shown in FIG. 8, in the lattice 92, water is stopped by applying putty as the water-stopping material 2 in a fillet shape to the joints between the adjacent waterstop plates 11, 12 and the abutting parts between the waterstop plates 11, 12 and the bottom surface A31 of the rectangular recess A3. Although not shown in the figure, the lattice 93 and the partition member 10 are also similarly sealed by applying putty. However, a water-stopping material other than the putty described above may be used as the water-stopping material 2.

[0031] (Masker installation process S3) The masker installation step S3 is a step of covering a part or the whole of the waterstop 1 with the masker 8. In the masker installation step S3, first, as shown in Fig. 11, a waterproof tape 6 is applied to the inspection target surface A along the waterstop 1 to be covered with the masker 8. Next, while pulling out the tape-like masker 8 from the roll, an adhesive tape 81 is applied to the upper surface of the waterproof tape 6 stretched on the inspection target surface A. Thereafter, the sheet portion 82 is unfolded from the masker 8, which has been folded in an accordion shape, and the sheet portion 82 is spread out so as to cover the waterstop 1 from above.

[0032] (Drain outlet sealing process S4) The drain outlet sealing step S4 is a step of placing a balloon 3 inside the drain outlet B and sealing the drain outlet B. In this step, as shown in FIG. 9, a deflated balloon 3 is placed inside the drain outlet B. The balloon 3 is placed above the connecting part B3 between the cylindrical mouth fitting B1 provided at the entrance of the drain outlet B and the drain pipe B2, or so as to straddle the connecting part B3 from top to bottom, in order to waterproof the connecting part B3. In this state, the manual air pump 5 is driven to send air into the balloon 3 through the air hose 4, thereby inflating the balloon 3. In this way, the balloon 3 waterproofs both the drain pipe B2 and the connecting part B3. The drain outlet sealing step S4 can be performed in parallel with the above steps or before or after the above steps, as long as it is performed before the test liquid storing step S5 described later.

[0033] (Test solution storage step S5) The test liquid storing step S5 is a step of storing a test liquid in each section. In the example of Fig. 1, test liquids containing fluorescent agents of different colors are stored in sections X, Y, and Z.

[0034] (Rainwater ingress point identification process S6) The rainwater intrusion point identification process S6 is a process for identifying a section including the intrusion point of the rainwater that is causing the leak. In this embodiment, fluorescent light is applied to the rainwater that has leaked into the building, and it is identified from which section among sections X, Y, and Z the rainwater has intruded based on the fluorescent color of the rainwater.

[0035] For example, if the test liquid L that has entered the building exhibits the fluorescent color of the test liquid L stored in section X, it is presumed that there is an invisible crack on the inspection target surface A in section X. Also, if the test liquid L that has entered the building exhibits the fluorescent color of the test liquid L stored in section Y, it is presumed that there is a leak at the boundary between the pigeon coop C and the inspection target surface A.

[0036] As described above, the drain outlet B in section Y has a cylindrical faucet B1 made of casting or the like at the entrance, and the drain pipe B2 is connected to the bottom of the faucet B1 (see FIG. 9). Reference symbol B3 indicates the connection between the faucet B1 and the drain pipe B2. A flange portion B1a that extends radially outward is provided at the upper end of the faucet B1, and the faucet B1 is connected to the waterproof layer A4 made of an asphalt sheet by fusing the flange portion B1a to the waterproof layer A4. In this embodiment, in the drain outlet sealing process S4, the connection part B3 between the mouth fitting B1 and the drain pipe B2 is sealed with a balloon 3, and the water pressure of the test liquid L is applied to the fused part B4 between the mouth fitting B1 and the waterproof layer A4. Therefore, if the test liquid L from section Y is the cause of the leak, it will be determined that the rainwater is entering through the fused part B4 and not the connection part B3.

[0037] If it is found that no rainwater has entered through the fused portion B4, the balloon 3 can be inflated below the connecting portion B3 to seal the drain pipe B2, thereby checking for water leakage from the connecting portion B3.

[0038] (effect) The rain leak inspection tool 100 and the rain leak inspection method according to the present embodiment have the following effects. (1) At least two waterstops 1 are connected at right angles by the notches 7, so that the waterstops 1 will not fall over when placed on the surface A to be inspected. (2) The connection parts between the waterstops 1 and the connection parts between the waterstops 1 and the surface to be inspected are sealed by the waterstop material 2, so that the test liquid L can be stored within the area surrounded by the waterstop 1 and the water pressure of the test liquid L can be applied to the point where rainwater enters. (3) When the balloon 3 is used to waterproof the drain pipe B2, it also waterproofs the connection part B3 between the fitting B1 of the drain outlet B and the drain pipe B2, making it easy to identify leakage from the fused part B4 between the fitting B1 and the waterproof layer A4. (4) Since the water stop 1 is covered with a masker, even if the water stop is made of a board that is easily permeated with liquid, such as a plywood board or a concrete panel, the test liquid can be prevented from permeating therethrough.

[0039] As described above, the present invention is not limited to the above-mentioned embodiment, and for example, the waterstop may have three or more cuts. If the drain outlet is not inspected, the balloon may not be provided, and the drain outlet sealing process may not be performed. The waterstop may not be covered with a masker.
