Description

  The present invention relates to a diagnostic kit for diagnosing the presence or absence of deterioration in a waterproof sheet used in a waterproof structure for waterproofing a casing, and a method for diagnosing the presence or absence of deterioration in a waterproof sheet using such a diagnostic kit.

  In recent years, with the demand for higher durability of buildings, a waterproof sheet structure in which a waterproof sheet (resin sheet) is laid and used has been adopted on many rooftops and verandas of buildings (for example, Patent Document 1). reference.).

  This sheet waterproof structure includes, for example, a waterproof sheet and a plurality of fixed disks, and bonds (fixes) a waterproof sheet laid on at least a part of the casing to the casing via the fixed disk. By adopting the configuration, waterproofing against rain water and the like on the housing is ensured.

  In the sheet waterproof structure having such a structure, the waterproof sheet contains, for example, a vinyl chloride resin and a plasticizer, and the plasticizer is waterproofed over time by being exposed to rainwater or sunlight. As a result, the waterproof sheet is reduced in flexibility, resulting in a crack or breakage in the waterproof sheet, and the problem that water enters the casing itself. There arises a problem that the waterproof property is lowered.

  Therefore, prior to the occurrence of cracks or breaks in the waterproof sheet, for example, Patent Document 2 proposes a diagnostic method for knowing the deterioration of the waterproof sheet, that is, the state of deterioration of the waterproof sheet. However, in such a diagnostic method, in order to obtain a diagnostic sample (section) used for diagnosis, there has been a problem that a part of the waterproof sheet laid on the housing has to be cut off and the waterproof sheet itself is damaged. .

  Hereinafter, a diagnostic kit and a diagnostic method using the diagnostic kit of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

  First, prior to explaining the diagnostic kit of the present invention and the diagnostic method using the diagnostic kit, a sheet waterproof structure applied to a housing to which the diagnostic kit of the present invention is applied will be described.

<Sheet waterproof structure>
FIG. 1 is a partial perspective view partially showing an embodiment of a sheet waterproof structure applied to a housing. In the following description, the upper side in FIG. 1 is referred to as “upper” and the lower side is referred to as “lower”. Further, in FIG. 1, for convenience of explanation, the floor portion and the wall portion included in the casing are partially illustrated without showing the entire casing provided with the waterproof sheet structure.

  The waterproof sheet structure 10 is applied to a housing 100 having a floor portion 101 and a wall portion 102 (rise portion) provided so as to surround the outer edge of the floor portion 101. A cross sheet 30 laid on the floor 101, a waterproof sheet 20 laid on the cross sheet 30 and the wall 102, an arrangement member 50, and a fixed disk (not shown). .

  The placement member 50 has a bottom portion 51 and a rising surface 52, each of which has a rectangular shape as a whole. The placement member 50 is disposed at the boundary between the floor portion 101 and the wall portion 102. The fixed sheet is fixed to the floor portion 101 via the cross sheet 30 with a fixed screw with a fixing screw, and in this state, the waterproof sheet 20 composed mainly of a resin material such as a vinyl chloride resin, The cross member 30 (floor portion 101) and the wall portion 102 are covered with the arrangement member 50, the fixing disc and the fixing screw, and are fixed to the fixing member and the fixing disc, thereby ensuring the waterproofness of the casing 100. Is done.

  That is, the waterproof sheet 20 is exposed to sunlight and rainwater, and the casing 100 is prevented from being directly exposed to sunlight and rainwater, so that the waterproofness of the casing 100 is ensured. In addition, the upper surface of the fixed disk and the lower surface of the waterproof sheet 20 are joined, whereby the floor portion 101 and the waterproof sheet 20 are joined via the fixed disk, and as a result, the waterproof sheet against wind and the like. 20 is fixed to the casing 100 without being peeled off.

  Both the arrangement member 50 and the fixed disk are composed of a metal plate and a resin layer covering the surface of the metal plate.

  The metal plate is composed of, for example, a stainless steel plate, a steel plate such as an iron plate, an aluminum plate, a copper plate, or the like, and is preferably a steel plate.

  Further, the thickness of the metal plate is not particularly limited, but is preferably about 0.1 mm or more and 3 mm or less, and more preferably about 0.3 mm or more and 2.5 mm or less.

  Examples of the resin constituting the resin layer include a vinyl chloride resin such as polyvinyl chloride, a polyolefin resin, an ethylene vinyl acetate copolymer, and the like. Although it can be used, it is preferably a vinyl chloride resin (particularly polyvinyl chloride). That is, it is preferable that it is the same or the same as resin which comprises the waterproof sheet 20 mentioned later. Thereby, the adhesiveness of the resin layer and the waterproof sheet 20 can be improved. Furthermore, since polyvinyl chloride is excellent in solvent weldability and heat-fusibility, the above effects can be exhibited more significantly and corrosion of the metal plate can be more reliably prevented.

  Moreover, other materials, such as a plasticizer mentioned in the constituent material of the waterproof sheet 20 mentioned later, a stabilizer, may be contained in resin which comprises this resin layer.

  Moreover, the thickness of the resin layer is not particularly limited, but is preferably 0.1 mm or more, and more preferably 0.3 mm or more and 0.8 mm or less. Thereby, even if stress acts on the resin layer due to the waterproof sheet 20 being blown with wind, it is possible to accurately suppress the occurrence of cracks and breaks in the resin layer.

  The waterproof sheet 20 has a sheet shape (plate shape), and covers the cross sheet 30 (floor portion 101) and the wall portion 102 together with the arrangement member 50 and the fixed disk.

  Thereby, the waterproof sheet 20 is exposed to sunlight and rainwater, and the casing 100 is prevented from being directly exposed to sunlight and rainwater, so that the waterproofness of the casing 100 is ensured.

  Such a waterproof sheet 20 is formed of a resin sheet containing a resin material and a plasticizer.

  The resin material is not particularly limited, and examples thereof include a vinyl chloride resin such as polyvinyl chloride, a polyolefin resin, an ethylene vinyl acetate copolymer, and the like, and one or more of these are combined. Can be used. Among these, a vinyl chloride resin is preferable. Thereby, the solvent weldability and heat-fusibility of the waterproof sheet 20 can be made excellent.

  The vinyl chloride resin is not particularly limited as long as it is a polymer containing vinyl chloride, that is, an oligomer, a prepolymer and a polymer. For example, a vinyl chloride monomer or vinyl chloride and vinyl acetate, ethylene Or a copolymer with propylene and the like, and a mixture of two or more of these polymers.

  Further, the plasticizer is contained for imparting excellent flexibility to the waterproof sheet 20, and specific examples thereof are not particularly limited. For example, DOP (dioctyl phthalate), DBP (dibutyl phthalate), DIBP (diisobutyl) are included. Phthalate), phthalate plasticizers such as DHP (diheptyl phthalate), aliphatics such as DOA (di-2-ethylhexyl adipate), DIDA (diisodecyl adipate), DOS (di-2-ethylhexyl sebacate) Examples include dibasic acid ester plasticizers, aromatic carboxylate plasticizers such as ethylene glycol benzoates, and trimellitic acid ester plasticizers such as TOTM (trioctyl trimellitate). Use one or more of these in combination It is possible.

  Moreover, the content rate of the plasticizer in the waterproof sheet 20 is not particularly limited, but is preferably 20% by mass or more and 75% by mass or less, and more preferably 25% by mass or more and 60% by mass or less. Thereby, the softness | flexibility which was excellent in the waterproof sheet 20 can be provided reliably, and the function as a waterproof sheet which prevents permeation of the water to a housing can be exhibited reliably.

  The waterproof sheet 20 may further contain various stabilizers, various antioxidants, various ultraviolet absorbers, processing aids, lubricants, fillers, flame retardants, coloring materials, and the like.

  Examples of the stabilizer include zinc glycine and the like. In this case, examples of the stabilizer include tricresyl phosphate (TCP), trixyl phosphate (TXP), tributyl phosphate (TBP), and phosphoric acid. Examples thereof include organic phosphates such as tri-2-ethylhexyl and 2-ethylhexyl diphenyl phosphate.

  From the above, the waterproof sheet 20 is preferably composed of a vinyl chloride resin sheet containing a vinyl chloride resin and a plasticizer. Thereby, the said effect can be exhibited more notably.

  The waterproof sheet 20 is composed of a single layer of the resin sheet, for example, a fiber layer interposed in the middle of the thickness direction, that is, a first resin laminated in the thickness direction. The thing of the structure by which the fiber layer (fiber sheet) was clamped between the layer and the 2nd resin layer may be sufficient.

  The fiber layer is composed of an aggregate of fibers, and examples thereof include a cloth sheet such as a cloth such as a woven fabric or a non-woven fabric, a net formed with a plurality of lattices of warp and weft, and a waterproof sheet. By providing 20 with such a fiber layer, the strength (tear strength, tensile strength, etc.) and durability (resistance to repeated fatigue) of the waterproof sheet 20 can be improved.

  Moreover, although the thickness of the waterproof sheet 20 is not specifically limited, For example, it is preferable that it is about 0.5 mm or more and 3 mm or less, and it is more preferable that it is about 0.8 mm or more and 3 mm or less. Thereby, the floor part 101 and the wall part 102 can be reliably covered with the waterproof sheet 20. Moreover, even if the plasticizer leaks from the waterproof sheet 20 with the passage of time and the flexibility thereof decreases, it is possible to accurately prevent the waterproof sheet 20 from cracking or breaking at an early stage.

  The cross sheet 30 is laid on the floor portion 101 and is interposed between the floor portion 101 and the waterproof sheet 20.

  The cross sheet 30 is formed of, for example, an insulating cross sheet made of a woven fabric made of polyethylene. In place of this, a walking board made of a high-rigidity board such as a glass fiber fire prevention sheet, an aluminum foil laminate sheet for pinhole inspection, a calcium silicate board, an asbestos slate board, a lightweight cellular concrete board, etc. 101 may be laid on 101, and further provided with these as an upper layer, and as a lower layer, a laminate including a heat insulating layer (heat insulating material) composed of expanded polystyrene, polyurethane foam, polyisocyanurate foam, phenol foam, or the like. You may lay on the floor part 101. FIG. By interposing these sheets between the floor portion 101 and the waterproof sheet 20, the cushioning property, the insulating property, the heat insulating property, and the like of the sheet waterproof structure 10 can be ensured.

  In addition, in the sheet | seat waterproofing structure 10, installation to the floor part 101 of this cross sheet 30 may be abbreviate | omitted.

<Diagnostic kit>
In order to diagnose the presence or absence of deterioration of the waterproof sheet 20 provided in the sheet waterproof structure 10 having such a configuration and covering at least a part of the floor portion 101, the diagnostic kit 60 of the present invention is provided in a part on the waterproof sheet 20. Yes.

Hereinafter, the diagnostic kit 60 of the present invention will be described.
2 is a longitudinal sectional view taken along line AA of the diagnostic unit provided in the diagnostic kit applied to the waterproof seat structure shown in FIG. 1, and FIG. 3 is a diagnostic provided in the diagnostic kit applied to the waterproof seat structure shown in FIG. It is a top view in the B section of a part, and a top view showing a display part with which a diagnostic kit given to a sheet waterproof structure shown in Drawing 4 and Drawing 1 is provided. In the following description, the upper side in FIG. 2 is referred to as “upper”, the lower side is referred to as “lower”, the front side in FIG. 3 and FIG. 4 is referred to as “upper”, and the rear side in FIG. .

  In this embodiment, the diagnostic kit 60 is formed between the waterproof sheet 20 and the diagnostic sheet 74, which is laid on a part of the waterproof sheet 20 and joined to the waterproof sheet 20 at the edge. The diagnostic unit 70 includes a protective sheet 71, a hard plate 72, and a non-bonded sheet 73 that are housed in the space and stacked sequentially from the waterproof sheet 20 side.

  In the diagnostic kit 60 (diagnostic unit 70) having such a configuration, the protective sheet 71, the hard plate 72, and the non-bonded sheet 73 constitute an inclusion interposed between the waterproof sheet 20 and the diagnostic sheet 74. A part of the hard plate 72 that functions as a main body is joined to the diagnostic sheet 74.

  Here, the diagnostic kit 60 of the present invention will be described in detail in a diagnostic method to be described later, but the installation of the diagnostic kit 60 is combined with a part of the waterproof sheet 20 at the time of constructing the waterproof sheet structure 10 for the housing 100. After that, at a time when the waterproof sheet is expected to deteriorate, a part of the diagnostic sheet 74 included in the diagnostic kit 60 is cut as a section with a cutter or the like, and the waterproof sheet 20 is deteriorated based on the state of the section. Diagnose the presence or absence of.

  In this way, a part of the diagnostic sheet 74 provided in the diagnostic kit 60 provided in advance on the waterproof sheet 20 is cut out as a section, thereby diagnosing the state of deterioration of the waterproof sheet 20 without cutting off the waterproof sheet 20 itself. can do. Further, when a section is cut using a cutter or the like, an inclusion is interposed between the waterproof sheet 20 and the diagnostic sheet 74, and the inclusion serves as a so-called cutting board on which the diagnostic sheet 74 is placed. Since the function is exhibited, it is possible to prevent the waterproof sheet 20 from being cut off, that is, the waterproof sheet 20 can be prevented from being damaged.

  The diagnostic sheet 74 is laid on a part of the waterproof sheet 20 (in the present embodiment, the center part of the floor 101), and is joined to the waterproof sheet 20 at an edge thereof.

  A part of the diagnostic sheet 74 is cut as a section with a cutter or the like, and the presence or absence of deterioration of the waterproof sheet 20 is diagnosed based on the state of the section, that is, the content of the plasticizer remaining in the section. Used for.

  Such a diagnostic sheet 74 is preferably of the same type as the waterproof sheet 20 described above, more preferably of the same lot as the waterproof sheet 20, and is used when the sheet waterproof structure 10 is provided. More preferably, the remaining portion of the waterproof sheet 20 is used as the diagnostic sheet 74. In the present invention, as described above, a part of the diagnostic sheet 74 is cut out, but the deterioration of the waterproof sheet 20 is based on the information obtained by confirming the state of the section, that is, the plasticizer content in the section. However, by using these as the diagnostic sheet 74, the diagnosis result of the presence or absence of deterioration in the waterproof sheet 20 can be made more reliable.

  The hard plate 72 constitutes a main body of inclusions, and in this embodiment, the overall shape is a flat plate, and constitutes an inclusion interposed between the waterproof sheet 20 and the diagnostic sheet 74, a part thereof, That is, in the present embodiment, the edge of the hard plate 72 (inclusion) from which the disposition of the non-bonded sheet 73 on the upper surface of the hard plate 72 is omitted is bonded to the diagnostic sheet 74.

  The hard plate 72 functions as a so-called cutting board on which the diagnostic sheet 74 is placed by being interposed as an inclusion between the waterproof sheet 20 and the diagnostic sheet 74. Therefore, when a part of the waterproof sheet 20 is cut using a cutter or the like, it is possible to reliably prevent the waterproof sheet 20 positioned below the hard plate 72 from being accidentally cut.

  The hard plate 72 is not particularly limited as long as it has such a strength that it is prevented from penetrating by a cutter or the like when being cut using a cutter or the like. In particular, it is preferable to have a metal plate, particularly a metal plate and the surface of this metal plate. A resin-coated metal plate composed of a coating layer to be coated is preferable. Thus, by setting it as the structure provided with a metal plate, the state of the inclusion covered with the diagnostic sheet | seat 74 can be closely approximated to the state of the sheet | seat waterproof structure 10 coat | covered with the waterproof sheet 20. FIG. Therefore, by diagnosing the diagnostic sheet 74, it is possible to improve the accuracy of the diagnostic result that indirectly estimates the degree of deterioration and deterioration of the waterproof sheet 20. Moreover, since it is comprised by a metal plate and a coating layer, while the said effect can be exhibited more notably and the surface is coat | covered with the resin layer, it is diagnosed as a part of hard board 72. The sheet 74 can be bonded using the same technique as the bonding of the waterproof sheet 20 and the diagnostic sheet 74.

  In addition, as a metal plate and a resin layer, the thing similar to the metal plate and resin layer quoted with the arrangement | positioning member 50 and a fixed disk is mentioned.

  Examples of the resin material constituting the resin plate include polystyrene resins, polyethylene resins, polypropylene resins, polyester resins such as polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), polycarbonate resins, and vinyl chloride. Resin, polyacetal resin, etc. are mentioned, Among these, it can be used 1 type or in combination of 2 or more types.

  In the present embodiment, the region where a part of the hard plate 72 is bonded to the diagnostic sheet 74 coincides with the region where the disposition of the non-bonded sheet 73 on the upper surface of the hard plate 72 is omitted, The edge of the hard plate 72 (inclusion) is joined to the diagnostic sheet 74. As a result, the diagnostic section 74 is cut out in the region where the non-bonded sheet 73 is disposed on the upper surface of the hard plate 72, that is, in the region corresponding to the central portion of the hard plate 72, thereby reliably diagnosing the obtained section. It can be separated from the kit 60.

  Further, in the present embodiment, the hard plate 72 includes a plurality (12 pieces) of projecting portions 90 provided on the upper surface thereof so as to project on the extended lines of the respective sides (four sides) surrounding the non-bonding sheet 73. Yes. Accordingly, by disposing the hard plate 72 in the space formed between the waterproof sheet 20 and the diagnostic sheet 74, when the upper surface of the hard plate 72 is covered with the diagnostic sheet 74, these protrusions The diagnostic sheet 74 follows the 90 shape. Therefore, even if the upper surface of the hard plate 72 is covered with the diagnostic sheet 74, the position of the protrusion 90 can be visually recognized on the upper surface of the diagnostic sheet 74 (the surface opposite to the inclusion of the diagnostic sheet 74). it can. Therefore, the position of the non-bonding sheet 73 where the protrusions 90 are arranged on the hard plate 72, that is, the region where the protrusions 90 are not bonded to the hard plate 72 (inclusions) of the diagnostic sheet 74 is the upper surface of the diagnostic sheet 74. The method of using this marker will be described in detail in the diagnostic kit construction method to be described later.

  In this embodiment, the non-bonded sheet 73 is a sheet material having a rectangular shape in plan view, and is interposed between the diagnostic sheet 74 and the hard plate 72, and is a diagnostic sheet at the center of the hard plate 72. Two of them are arranged side by side along the longitudinal direction of the diagnostic sheet 74.

  The non-bonded sheet 73 is bonded to the hard plate 72 on the lower surface, but is not bonded to the diagnostic sheet 74 on the upper surface. Thus, the diagnostic sheet 74 is cut off in the region where the non-bonding sheet 73 is disposed on the upper surface of the hard plate 72, that is, the diagnostic sheet 74 is cut along the outer shape of the non-bonding sheet 73. The section to be obtained can be reliably separated from the diagnostic kit 60.

  A plurality (two) of non-bonded sheets 73 are arranged (bonded) on the hard plate 72 side by side. As a result, the diagnostic sheet 74 is cut out corresponding to each outer shape, and the diagnostic sheet 74 is diagnosed using the obtained slices, so that one diagnostic kit 60 can be used multiple times (2 Diagnosis of the diagnostic sheet 74 can be carried out. Therefore, it is possible to know a change with time in the content of the plasticizer in the diagnostic sheet 74 by shifting the diagnosis timing of the diagnostic sheet 74 a plurality of times. Therefore, the change with time of the content of the plasticizer in the waterproof sheet 20 can be estimated.

  The non-bonding sheet 73 is made of, for example, an adhesive tape. As the adhesive tape, for example, a base made of a resin material such as vinyl chloride, polyethylene, or polyimide and / or a metal material such as aluminum or copper. What formed the adhesion layer on the material is mentioned.

  In this embodiment, the protective sheet 71 is a sheet material having a rectangular shape in plan view, and is interposed between the waterproof sheet 20 and the hard plate 72, and has an edge on the waterproof sheet 20 side of the hard plate 72. The portion is arranged (laid) in a state of protruding beyond the end portion of the hard plate 72. Thereby, it can prevent reliably that the edge part of the hard board 72 contacts the waterproof sheet 20. FIG. Therefore, even if a displacement of the hard plate 72 occurs in the space formed between the waterproof sheet 20 and the diagnostic sheet 74, the end of the hard plate 72 (top) causes the waterproof sheet 20 to It is possible to reliably prevent the surface from being damaged.

  Further, the protective sheet 71 is not bonded to the waterproof sheet 20 and the hard plate 72 on the lower surface and the upper surface, respectively. Thereby, in the space formed between the waterproof sheet 20 and the diagnostic sheet 74, when the hard plate 72 is unintentionally displaced, the position of the protective sheet 71 that contacts the end of the hard plate changes. Therefore, it is possible to accurately suppress or prevent the protective sheet 71 from being locally damaged.

  The protective sheet 71 is not particularly limited as long as it is made of a softer material than the hard plate 72, but the above-described cross sheet 30 is preferably used. By using the cross sheet 30 as the protective sheet 71, the waterproof sheet 20 can be reliably protected from the end of the hard plate 72. Further, the state of the inclusion covered with the diagnostic sheet 74 can be made to closely approximate the state of the sheet waterproof structure 10 covered with the waterproof sheet 20. Therefore, by diagnosing the diagnostic sheet 74, it is possible to improve the accuracy of the diagnostic result that indirectly estimates the degree of deterioration and deterioration of the waterproof sheet 20.

  Note that the laying of the protective sheet 71 between the waterproof sheet 20 and the hard plate 72 can be omitted. In this case, it is preferable that the hard board 72 and the waterproof sheet 20 are joined. By adopting a configuration in which the hard plate 72 and the waterproof sheet 20 are joined, it is possible to reliably prevent the hard plate 72 from being displaced with respect to the waterproof sheet 20. The end portion (top portion) of the plate 72 can reliably prevent the surface of the waterproof sheet 20 from being damaged.

  Further, as shown in FIG. 1, the diagnostic kit 60 further includes a display unit 80 (display sticker) attached to a position adjacent to the diagnostic unit 70 on the waterproof sheet 20.

  In this display unit 80, the construction position of the diagnostic unit 70, the handling precautions of the diagnostic unit 70, the contact information, etc. are described (see FIG. 4), whereby the diagnostic unit 70 is stepped on by a third party. Can be reliably prevented from being removed or unintentionally removed.

  The above diagnostic kit 60 is installed with respect to the waterproof sheet 20 with which the sheet | seat waterproof structure 10 is provided, for example with the construction method as shown below.

<Diagnosis kit installation method>
5-8 is a top view for demonstrating the construction method which constructs a diagnostic kit in the waterproof sheet with which the sheet | seat waterproof structure shown in FIG. 1 is provided.

  Hereinafter, each process of the construction method of constructing the diagnostic kit 60 on the waterproof sheet 20 will be described in detail.

  In the following, an example in which the hard plate 72 includes a metal plate and a coating layer that covers the surface of the metal plate will be described.

  [1A] First, after the construction of the sheet waterproof structure 10 on the housing 100, the hard plate 72 and the protective sheet 71 prepared in advance are arranged with the protective sheet 71 on the lower side (the four sides) of the protective sheet 71. In a state of protruding beyond the end portion of the hard plate 72, the hard plate 72 is placed on the central portion of the protective sheet 71 and placed on the waterproof sheet 20 provided in the waterproof sheet structure 10 (see FIG. 5).

  The position where the hard plate 72 and the protective sheet 71 are placed, that is, the position where the diagnostic kit 60 (diagnostic unit 70) is provided is the most sunny position in the waterproof sheet structure 10 applied to the housing 100, avoiding under water. Is preferably selected. Thereby, the diagnosis of the waterproof sheet 20 at the position where the deterioration is most remarkable in the waterproof sheet structure 10 can be performed indirectly.

  In the present embodiment, when the protective sheet 71 and the hard plate 72 are placed on the waterproof sheet 20 with the protective sheet 71 on the lower side and the protective sheet 71 and the hard plate 72 being superposed, the waterproof sheet is used. 20 and the protective sheet 71 and between the protective sheet 71 and the hard plate 72 are not joined.

  Further, a total of 12 protrusions are provided on one surface of the hard plate 72, and the top surface of the waterproof sheet 20 is interposed via the protective sheet 71 so that this one surface is the upper side, that is, the upper surface. A hard plate 72 is placed on the surface.

  Further, as described above, the cross sheet 30 is preferably used as the protective sheet 71. In this case, the unnecessary portion of the cross sheet 30 is prepared by cutting in advance when the waterproof sheet structure 10 is constructed. The

  [2A] Next, two non-bonded sheets 73 arranged along the longitudinal direction of the hard plate 72 are formed in the central portion of the hard plate 72.

  In the present embodiment, these non-bonded sheets 73 are bonded to the upper surface of the hard plate 72. In this case, the protrusion 90 formed on the upper surface of the hard plate 72 and an adhesive tape are used, for example, It is formed as follows.

  [2A-1] First, a line connecting the protrusions 90 formed on the hard plate 72 is formed on the hard plate 72.

  More specifically, the line a is connected by connecting the protrusions 90 at the positions A and H, the line b is connected by connecting the protrusions 90 at the positions B and G, and the protrusions at the positions C and F are connected. A line c is formed by connecting 90 to each other, a line d is formed by connecting the protrusions 90 at the positions D and E, a line e is connected by connecting the protrusions 90 at the positions I and J, a position L and a position Lines f are formed on the hard plate 72 by connecting the protruding portions 90 at K (see FIG. 6).

  [2A-2] Next, two non-bonded sheets 73 are formed at the center of the hard plate 72 by sticking an adhesive tape to the region surrounded by each line on the hard plate 72.

  More specifically, as shown in FIG. 6, the adhesive tape is respectively applied to the area surrounded by the lines a, b, e, and f and the area surrounded by the lines c, d, e, and f. As shown in FIG. 7, two non-bonded sheets 73 arranged side by side in the longitudinal direction of the hard plate 72 are formed on the hard plate 72.

  [3A] Next, a diagnostic sheet 74 is prepared, and the hard plate 72 is covered with the diagnostic sheet 74 so that the hard plate 72 is arranged at the center of the diagnostic sheet 74, and then the diagnostic sheet 74. The diagnostic sheet 74 is fixed to the waterproof sheet 20 by joining the edges of the sheet to the waterproof sheet 20 (see FIG. 8).

  When the diagnostic sheet 74 is fixed to the waterproof sheet 20, a space is formed between the waterproof sheet 20 and the diagnostic sheet 74, and the protective sheet 71, the hard plate 72, and the non-bonded sheet 73 are formed in this space. Contained inclusions are stored.

  In the present embodiment, when the edge of the diagnostic sheet 74 and the waterproof sheet 20 are joined, the edge of the hard plate 72 (part of inclusions) exposed from the non-joined sheet 73 and the diagnostic sheet 74 are combined. And join.

  The bonding between the diagnostic sheet 74 and the waterproof sheet 20 and the bonding between the diagnostic sheet 74 and the hard plate 72 include, for example, a welding method using a solvent, a thermal fusion method for blowing hot air, and an adhesive. It can be carried out using any of the bonding methods such as bonding via a bonding method, but it is particularly preferred that the bonding method is used.

  When the welding method (brush welding method) is used, these joinings are performed as follows, for example.

  [3A-1] First, before laying the diagnostic sheet 74 on the waterproof sheet 20 and the inclusions (the protective sheet 71, the hard plate 72, and the non-bonded sheet 73), the waterproof sheet 20 is bonded to the diagnostic sheet 74. A solvent (soluble solvent) is applied (supplied) to the region to be exposed and the resin layer exposed at the edge of the hard plate 72 using a brush brush or the like. Thereby, the upper surface of the waterproof sheet 20 and the upper surface of the resin layer come into contact with the solvent, and as a result, are in a molten state.

  At this time, the non-bonding sheet 73 attached to the central portion of the hard plate 72 functions as a mask that prevents the resin layer located in a region other than the edge of the hard plate 72 from coming into contact with the solvent. This resin layer can be reliably prevented from being melted.

  [3A-2] Next, the diagnostic sheet 74 is laid on the waterproof sheet 20 and the inclusions.

  [3A-3] Next, the diagnostic sheet 74 is pressed by an operator's hand or the like, thereby fixing the lower surface of the diagnostic sheet 74 to the upper surface of the waterproof sheet 20 and the upper surface of the resin layer included in the hard plate 72. As a result, the diagnostic sheet 74 is joined to the waterproof sheet 20 and the edge (part) of the hard plate 72. At this time, in the region where the non-bonded sheet 73 is interposed between the diagnostic sheet 74 and the hard plate 72, the hard plate 72 and the non-bonded sheet 73 are bonded, but the diagnostic sheet 74 and the non-bonded sheet are not bonded. The sheet 73 is not joined.

  The diagnostic unit 70 is fixed to the waterproof sheet 20 through such steps [3A-1] to [3A-3].

  The solvent (soluble solvent) is not particularly limited as long as the waterproof sheet 20 and the resin layer can be in a molten state, but when the resin layer is made of a resin containing a vinyl chloride resin, for example, Examples include tetrahydrofuran (THF) nitrobenzene, carbon tetrachloride, pyridine, ethyl acetate, cyclohexanone, ketones such as methyl ethyl ketone (MEK), alcohols such as toluene, methyl alcohol, isopropyl alcohol, etc., one or two of these More than one species can be used in combination, and among them, THF is preferable. THF is a solvent having excellent volatility, and can firmly fix the waterproof sheet 20 and the resin layer to the waterproof sheet 20 and the resin layer because THF can surely bring the waterproof sheet 20 and the resin layer into a molten state.

  In the bonding method using an adhesive, the adhesive is applied to the upper surfaces of the waterproof sheet 20 and the edge of the hard plate 72, and then the diagnostic sheet 74 is bonded to the upper surface via the adhesive. Thereafter, the diagnostic sheet 74 is bonded to these by solidifying or curing the adhesive, and therefore, when the bonding method is used, the formation of the non-bonded sheet 73 on the upper surface of the hard plate 72 is omitted. be able to.

  Further, as described above, the waterproof sheet 20 is preferably used as the diagnostic sheet 74. In this case, the unnecessary part of the waterproof sheet 20 is prepared by cutting in advance when the waterproof sheet structure 10 is constructed. Is done.

  [4A] Next, a display unit 80 made of a sealing material is pasted in the vicinity of the diagnostic unit 70 fixed on the waterproof sheet 20.

  The diagnostic kit 60 is provided in a part of the waterproof sheet 20 through the above steps [1A] to [4A], and the diagnostic method of the present invention includes these steps [1A] to [4A]. The installation process is configured.

  The diagnostic kit 60 applied to the waterproof sheet 20 as described above includes the waterproof sheet structure 10 using, for example, a section obtained by cutting out the diagnostic sheet 74 by a diagnostic method as described below. The presence or absence of deterioration of the waterproof sheet 20 is diagnosed.

<Diagnostic method using diagnostic kit>
[1B] First, an area corresponding to the non-bonded sheet 73 provided on the hard plate 72 is cut out from the diagnostic sheet 74 included in the diagnostic unit 70 to obtain a section.

  Here, in the present embodiment, a plurality of projecting portions 90 are provided on the upper surface of the hard plate 72, and the diagnostic sheet 74 covering the upper surface of the hard plate 72 corresponding to the shape of the projecting portions 90 as described above. Therefore, the position of the protrusion 90 is visually recognized with the upper surface of the hard plate 72 covered with the diagnostic sheet 74. Therefore, in the following, a method for obtaining a section from the diagnostic sheet 74 using these protrusions 90 will be described.

  [1B-1] First, a line (inking line) connecting the protrusions 90 is formed on the diagnosis sheet 74 using the protrusions 90 that are visually recognized when the diagnosis sheet 74 follows (covers). .

  More specifically, in the same manner as in the above step [2A-2], the line a is connected by connecting the protrusions 90 at the positions A and H, and the protrusions 90 at the positions B and G are connected. Line b is connected by connecting protrusions 90 at positions C and F, line c is connected by connecting protrusions 90 at positions D and E, and line d is connected between protrusions 90 at positions I and J. In this step [1B-1], the line e is connected on the diagnostic sheet 74 in place of the hard plate 72, by connecting the line e by connecting the protrusions 90 at the positions L and K. To form.

  [1B-2] Next, with respect to one of the two regions surrounded by each line on the diagnostic sheet 74, a hard plate is used from the upper surface side of the diagnostic sheet 74 using a cutter or the like along each line. By inserting the blade until it reaches 72, the diagnostic sheet 74 is cut (cut) in accordance with the shape of the non-bonded sheet 73 positioned below the diagnostic sheet 74.

  At this time, since the diagnostic sheet 74 and the non-bonded sheet 73 are not bonded at a position corresponding to the non-bonded sheet 73 of the diagnostic sheet 74, the diagnostic sheet 74 corresponds to the shape of the non-bonded sheet 73. Can be obtained in a state where the section obtained by this cutting is cut off from the hard plate 72 (diagnostic unit 70).

  By using the protrusion 90 located on the extension line of each side (four sides) that determines the outer shape of the non-bonding sheet 73 as in the above steps [1B-1] and [1B-2], The position of the non-bonded sheet 73 disposed on the hard plate 72, that is, the region that is not bonded to the hard plate 72 (inclusion) of the diagnostic sheet 74 can be determined. In other words, the protrusion 90 can be used as a marker for recognizing the position of the non-bonded sheet 73, that is, the region not bonded to the hard plate 72 of the diagnostic sheet 74 from the upper surface of the diagnostic sheet 74. Therefore, the section obtained by cutting the diagnostic sheet 74 can be obtained in a state of being reliably separated from the hard plate 72 (diagnostic unit 70).

  Further, since the blade such as a cutter is in contact with the hard plate 72 when the diagnostic sheet 74 is cut, the waterproof sheet 20 located below the hard plate 72 is damaged. Can be accurately prevented.

  By such a step [1B], in the diagnostic method of the present invention, in the state where the inclusion is interposed between the waterproof sheet 20 and the diagnostic sheet 74, the region that is not joined to the inclusion of the diagnostic sheet 74 A sampling process is obtained in which a section is obtained by cutting out.

  [2B] Next, the presence or absence of deterioration of the waterproof sheet 20 is diagnosed based on the state of the section derived from the diagnostic sheet 74 (diagnosis step).

  In this embodiment, the diagnosis of the presence or absence of the deterioration of the waterproof sheet 20 is performed by measuring the content of the plasticizer remaining in the section and diagnosing the presence or absence of the deterioration of the waterproof sheet 20 based on the measured content. .

  According to the diagnostic method using the diagnostic kit 60 according to the steps [1B] and [2B] as described above, the deterioration state of the waterproof sheet 20 is diagnosed without damaging the waterproof sheet 20 included in the waterproof sheet structure 10. can do. And based on this diagnosis result, the repair time of the waterproof sheet 20, that is, whether or not the waterproof sheet structure 10 needs to be repaired can be determined.

  Moreover, the state of deterioration of the waterproof sheet 20 can be diagnosed over time by shifting the step [1B] and the step [2B] a plurality of times (in this embodiment, twice).

  As mentioned above, although the diagnostic kit and diagnostic method of this invention were demonstrated, this invention is not limited to these.

  For example, in the diagnostic kit of the present invention, each component can be replaced with any component that can exhibit the same function, or any component can be added.

  Furthermore, one or two or more steps for any purpose may be added to the diagnostic method of the present invention.
