Description

The present invention relates to a diagnostic kit for diagnosing the presence or absence of deterioration in a waterproof sheet used for a sheet waterproof structure for waterproofing a skeleton, 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 sheet waterproof structure in which a waterproof sheet (resin sheet) is laid is adopted on the rooftops and balconies of many buildings (for example, Patent Document 1). reference.).

This sheet waterproof structure includes, for example, a waterproof sheet and a plurality of fixed disks, and a waterproof sheet laid on at least a part of the skeleton is joined (fixed) to the skeleton via the fixed disk. With the configuration, waterproofness against rainwater and the like is ensured for the skeleton.

In the sheet waterproof structure having such a configuration, the waterproof sheet contains, for example, a vinyl chloride resin and a plasticizing agent, and when exposed to rainwater or sunlight, the plasticizing agent becomes a waterproof sheet over time. As a result, the waterproof sheet is cracked or broken due to the decrease in flexibility of the waterproof sheet, and water infiltrates into the skeleton itself, that is, the sheet waterproof structure. There is a problem that the waterproof property is lowered.

Therefore, for example, Patent Document 2 proposes a diagnostic method for knowing a decrease in the flexibility of the tarpaulin, that is, a state of deterioration of the tarpaulin, prior to the occurrence of cracks or breaks in the tarpaulin. However, in such a diagnostic method, in order to obtain a diagnostic sample (section) used for diagnosis, a part of the tarpaulin laid on the skeleton must be cut off, which causes a problem that the tarpaulin itself is damaged. ..

Hereinafter, the diagnostic kit of the present invention and the diagnostic method using the diagnostic kit will be described in detail based on the 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, the sheet waterproof structure applied to the skeleton to which the diagnostic kit of the present invention is applied will be described.

<Sheet waterproof structure>
FIG. 1 is a partial perspective view of an embodiment of a sheet waterproof structure applied to a skeleton. 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 provided in the skeleton are partially illustrated without showing the entire skeleton provided with the sheet waterproof structure.

The sheet waterproof structure 10 is applied to a skeleton 100 having a floor portion 101 and a wall portion 102 (rising portion) provided upright along the outer edge of the floor portion 101. It has 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). ..

Each of the arrangement members 50 has a bottom portion 51 and a rising surface 52 having a rectangular shape as a whole, and is arranged at a boundary portion between the floor portion 101 and the wall portion 102. Further, a plurality of fixed disks are predetermined. The waterproof sheet 20 is fixed to the floor 101 via a cross sheet 30 with a (constant) interval by fixing screws, and in this state, the waterproof sheet 20 composed of a resin material such as vinyl chloride resin as a main material is used. The cross sheet 30 (floor portion 101) and the wall portion 102 are fixed to the fixing member and the fixing disk together with the arrangement member 50, the fixing disk and the fixing screw, thereby ensuring the waterproofness of the skeleton 100. Will be done.

That is, the waterproof sheet 20 is exposed to sunlight and rainwater, and the skeleton 100 is prevented from being directly exposed to sunlight and rainwater, so that the waterproofness of the skeleton 100 is ensured. Further, the upper surface of the fixed disk and the lower surface of the waterproof sheet 20 are joined, whereby the floor 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 skeleton 100 without being peeled off.

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

This 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.

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 vinyl chloride-based resins such as polyvinyl chloride, polyolefin-based resins, ethylene-vinyl acetate copolymers, and the like, and one or more of these may be combined. Although it can be used, it is preferably a vinyl chloride resin (particularly polyvinyl chloride). That is, it is preferable that the resin is of the same type or the same as the resin constituting the waterproof sheet 20 described later. As a result, the adhesion between the resin layer and the waterproof sheet 20 can be improved. Further, since polyvinyl chloride is excellent in solvent-weldability and heat-weldability, the above-mentioned effect can be exhibited more remarkably, and corrosion of the metal plate can be more reliably prevented.

Further, the resin constituting this resin layer may contain other materials such as a plasticizer and a stabilizer mentioned in the constituent materials of the waterproof sheet 20 described later.

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. As a result, even if stress acts on the resin layer due to the waterproof sheet 20 being fanned by the wind, it is possible to accurately suppress the occurrence of cracks and breakage 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 fixing disc.

As a result, the waterproof sheet 20 is exposed to sunlight and rainwater, and the skeleton 100 is prevented from being directly exposed to sunlight and rainwater, so that the waterproofness of the skeleton 100 is ensured.

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

The resin material is not particularly limited, and examples thereof include vinyl chloride-based resins such as polyvinyl chloride, polyolefin-based resins, and ethylene-vinyl acetate copolymers, and one or more of these may be combined. Can be used. Among these, a vinyl chloride resin is preferable. As a result, the solvent-weldability and heat-sealing property of the waterproof sheet 20 can be made excellent.

The vinyl chloride-based 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 single polymer of vinyl chloride, vinyl chloride, vinyl acetate, and ethylene are used. , Or a copolymer with propylene or the like, or a mixture of two or more kinds of these polymers.

Further, the plasticizer is contained to impart excellent flexibility to the waterproof sheet 20, and specific examples thereof are not particularly limited, but for example, DOP (dioctylphthalate), DBP (dibutylphthalate), DIBP (diisobutyl). Phthalate), phthalate plasticizers such as DHP (diheptyl phthalate), aliphatics such as DOA (di-2-ethylhexyl adipate), DIDA (diisodecyl adipate), DOS (di-2-ethylhexyl sebasate) Examples thereof include dibasic acid ester-based plasticizers, aromatic carboxylic acid ester-based plasticizers such as ethylene glycol benzoates, and trimellitic acid ester-based plasticizers such as TOTM (Trioctyl Limeritate). One or a combination of two or more of these can be used.

The content 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. As a result, excellent flexibility can be reliably imparted to the waterproof sheet 20, and the function as a waterproof sheet that prevents water from entering the skeleton can be reliably exerted.

Further, 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 glycine zinc and the like, and examples of the stabilizing aid in this case include tricredyl phosphate (TCP), trixysilyl phosphate (TXP), tributyl phosphate (TBP) and phosphoric acid. Examples thereof include organic phosphate esters 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. As a result, the effect can be exerted more remarkably.

The waterproof sheet 20 is composed of a single layer of the resin sheet, or, for example, a fiber layer inserted in the middle of the resin sheet, that is, a first resin laminated in the thickness direction. A fiber layer (fiber sheet) may be sandwiched between the layer and the second resin layer.

This fiber layer is composed of an aggregate of fibers, and examples thereof include a cloth such as a woven fabric and a non-woven fabric, and a fiber sheet such as a net in which a plurality of lattices are formed by warp threads and weft threads. By providing the 20 with such a fiber layer, the strength (tear strength, tensile strength, etc.) and durability (repeated fatigue resistance characteristics) of the tarpaulin 20 can be improved.

The thickness of the waterproof sheet 20 is not particularly limited, but is preferably 0.5 mm or more and 3 mm or less, and more preferably 0.8 mm or more and 3 mm or less. As a result, the floor portion 101 and the wall portion 102 can be reliably covered with the waterproof sheet 20. Further, even if the plasticizer leaks from the waterproof sheet 20 over time and its flexibility is reduced, 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 cloth sheet 30 is composed of, for example, an insulating cloth sheet made of a woven cloth made of polyethylene. In place of this, a walking board made of high-rigidity boards such as glass fiber fireproof sheets, aluminum foil laminate sheets for pinhole inspection, calcium silicate boards, asbestos slate boards, and lightweight cellular concrete boards is used for the floor. It may be laid on 101, or a laminate having these as an upper layer and further having a heat insulating layer (heat insulating material) composed of expanded polystyrene, polyurethane foam, polyisocyanurate foam, phenol foam or the like as a lower layer. It may be laid on the floor 101. 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.

The laying of the cross sheet 30 on the floor 101 in the sheet waterproof structure 10 may be omitted.

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

Hereinafter, the diagnostic kit 60 of the present invention will be described.
FIG. 2 is a vertical sectional view taken along line AA of the diagnostic unit included in the diagnostic kit provided on the sheet waterproof structure shown in FIG. 1, and FIG. 3 shows the diagnosis provided on the diagnostic kit provided on the sheet waterproof structure shown in FIG. It is a plan view of the part B, and is a plan view which shows the display part provided with the diagnostic kit applied to the sheet waterproof structure shown in FIGS. 4 and 1. 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 of the paper in FIGS. 3 and 4 is referred to as "upper", and the back side of the paper is referred to as "lower". ..

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

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

Here, in the diagnostic kit 60 of the present invention, the detailed description will be given in the diagnostic method described later, but when the sheet waterproof structure 10 is constructed on the skeleton 100, the installation of the diagnostic kit 60 is combined with a part of the waterproof sheet 20. After that, when the deterioration of the waterproof sheet is expected, a part of the diagnostic sheet 74 provided in the diagnostic kit 60 is cut out as a section with a cutter or the like, and the deterioration of the waterproof sheet 20 is based on the state of the section. Diagnose the presence or absence of.

In this way, by cutting out a part of the diagnostic sheet 74 provided in the diagnostic kit 60 provided in advance on the waterproof sheet 20 as a section, the state of deterioration of the waterproof sheet 20 can be diagnosed without cutting the waterproof sheet 20 itself. can do. Further, when cutting a section using a cutter or the like, inclusions are interposed between the waterproof sheet 20 and the diagnostic sheet 74, and these inclusions serve as a mounting table, so-called cutting board, on which the diagnostic sheet 74 is placed. Since it exerts its function, it is possible to accurately prevent the waterproof sheet 20 from being cut off, that is, the waterproof sheet 20 from being damaged from this viewpoint as well.

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

A part of the diagnostic sheet 74 is cut out 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 providing the sheet waterproof structure 10. It is more preferable that the remaining portion of the waterproof sheet 20 that has been used is diverted 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 tarpaulin 20 is based on the information obtained by confirming the state of the section, that is, the content of the plasticizer in the section. By using these as the diagnostic sheet 74, the diagnosis result of the presence or absence of deterioration in the tarpaulin 20 can be made more reliable.

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

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

The hard plate 72 may have enough strength to prevent penetration by a cutter or the like when it is cut by a cutter or the like, and is not particularly limited, but for example, various resin materials. Examples thereof include a resin plate made of a metal plate, a metal plate made of various metal materials, and the like. Among them, a metal plate is preferably provided, and in particular, the metal plate and the surface of the metal plate are formed. It is preferably a resin-coated metal plate composed of a coating layer to be coated. By providing the metal plate in this way, the state of the inclusions covered with the diagnostic sheet 74 can be reliably approximated to 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 infers the degree of deterioration / deterioration of the waterproof sheet 20. Further, by forming the metal plate and the coating layer, the above effect can be exhibited more remarkably, and since the surface is coated with the resin layer, it is diagnosed as a part of the hard plate 72. The bonding with the waterproof sheet 74 can be performed by using the same method as the bonding between the waterproof sheet 20 and the diagnostic sheet 74.

Examples of the metal plate and the resin layer include the same metal plate and the resin layer as those mentioned in the arrangement member 50 and the fixed disk.

Examples of the resin material constituting the resin plate include polyester resins such as polystyrene resin, polyethylene resin, polypropylene resin, polyethylene terephthalate (PET), and polyethylene naphthalate (PEN), polycarbonate resin, and vinyl chloride. Examples thereof include resins and polyacetal resins, and one or a combination of two or more of these can be used.

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

Further, in the present embodiment, the hard plate 72 is provided with a plurality of (12) projecting portions 90 provided so as to project on the extension lines of each side (4 sides) surrounding the non-bonded sheet 73 on the upper surface thereof. There is. As a result, by arranging 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 protruding portions The diagnostic sheet 74 follows the shape of 90. Therefore, even if the upper surface of the hard plate 72 is covered with the diagnostic sheet 74, the position of the protruding portion 90 can be visually recognized on the upper surface of the diagnostic sheet 74 (the surface opposite to the inclusions of the diagnostic sheet 74). it can. Therefore, the position of the non-bonded sheet 73 in which these protrusions 90 are arranged on the hard plate 72, that is, the region not joined to the hard plate 72 (inclusion) of the diagnostic sheet 74 is the upper surface of the diagnostic sheet 74. Although it can be used as a marker to be recognized from the above, the method of using this marker will be described in detail in the method of constructing a diagnostic kit described later.

In the present embodiment, the non-bonded sheet 73 is a sheet material having a rectangular shape in a plan view, 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 the diagnostic sheets 74 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 thereof, but is not bonded to the diagnostic sheet 74 on the upper surface surface. As a result, the diagnostic sheet 74 is cut out in the region where the non-bonded sheet 73 is arranged on the upper surface of the hard plate 72, that is, the diagnostic sheet 74 is cut out along the outer shape of the non-bonded sheet 73. The section to be used can be reliably separated from the diagnostic kit 60.

Further, a plurality (two) non-bonded sheets 73 are arranged (joined) side by side on the hard plate 72. 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 sections, so that one diagnostic kit 60 is used a plurality of times (2). The diagnosis of the diagnostic sheet 74 can be carried out. Therefore, by shifting the diagnosis time of the diagnostic sheet 74 a plurality of times, it is possible to know the change over time in the content of the plasticizer in the diagnostic sheet 74. Therefore, it is possible to estimate the change over time in the content of the plasticizer in the waterproof sheet 20.

The non-bonded sheet 73 is composed of, for example, an adhesive tape, and the adhesive tape is a group composed of, for example, a resin material such as vinyl chloride, polyethylene, or polyimide and / or a metal material such as aluminum or copper. Examples thereof include those having an adhesive layer formed on the material.

In the present embodiment, the protective sheet 71 is a sheet material having a rectangular shape in a plan view, is interposed between the waterproof sheet 20 and the hard plate 72, and has an edge thereof 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. As a result, it is possible to reliably prevent the end portion of the hard plate 72 from coming into contact with the waterproof sheet 20. Therefore, even if the position of the hard plate 72 is displaced in the space formed between the waterproof sheet 20 and the diagnostic sheet 74, the end (top) of the hard plate 72 causes the waterproof sheet 20 to be displaced. It is possible to surely prevent the surface from being scratched.

Further, the protective sheet 71 is not joined to the waterproof sheet 20 and the hard plate 72 on the lower surface and the upper surface, respectively. As a result, when the hard plate 72 is unintentionally misaligned in the space formed between the waterproof sheet 20 and the diagnostic sheet 74, the position of the protective sheet 71 that comes into contact with 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 material that is softer than the hard plate 72, but the above-mentioned 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 portion of the hard plate 72. Further, the state of the inclusions covered with the diagnostic sheet 74 can be reliably approximated to 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 infers the degree of deterioration / deterioration of the waterproof sheet 20.

The laying of the protective sheet 71 between the waterproof sheet 20 and the hard plate 72 may be omitted. In this case, it is preferable that the hard plate 72 and the waterproof sheet 20 are joined. By forming the structure 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, and therefore, even with such a configuration, it is hard. The end (top) of the plate 72 can reliably prevent the surface of the waterproof sheet 20 from being scratched.

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

The display unit 80 describes the construction position of the diagnostic unit 70, precautions for handling the diagnostic unit 70, contact information, etc. (see FIG. 4), whereby the diagnostic unit 70 is trampled by a third party. It can be surely prevented from being damaged or unintentionally removed.

The diagnostic kit 60 as described above is installed on the waterproof sheet 20 included in the sheet waterproof structure 10 by, for example, the following construction method.

<How to install the diagnostic kit>
5 to 8 are plan views for explaining a construction method for applying the diagnostic kit to the waterproof sheet provided in the sheet waterproof structure shown in FIG. 1.

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

In the following, a case where a hard plate 72 composed of a metal plate and a coating layer covering the surface of the metal plate is used will be described as an example.

[1A] First, after the construction of the sheet waterproof structure 10 on the skeleton 100, the hard plate 72 and the protective sheet 71 prepared in advance are provided with the protective sheet 71 on the lower side, and the edges (four sides) of the protective sheet 71 are formed. The hard plate 72 is superposed on the central portion of the protective sheet 71 in a state of protruding beyond the end portion of the hard plate 72, and is placed on the waterproof sheet 20 provided in the sheet waterproof 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 (diagnosis unit 70) is provided, is the most sunny position in the sheet waterproof structure 10 provided on the skeleton 100, avoiding underwater. Is preferably selected. As a result, the diagnosis of the waterproof sheet 20 at the position where the deterioration is most remarkable in the sheet waterproof structure 10 can be indirectly performed.

Further, in the present embodiment, the waterproof sheet is 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 overlapped with each other. No joint is formed between 20 and the protective sheet 71, and between the protective sheet 71 and the hard plate 72.

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

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

[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, using the protruding portion 90 formed on the upper surface of the hard plate 72 and the adhesive tape, for example, the following 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 90 at the positions C and F are connected to each other. Line c by connecting 90s, line d by connecting protrusions 90s at positions D and E, line e by connecting protrusions 90s at positions I and J, positions L and positions. Lines f are formed on the hard plate 72 by connecting the protrusions 90 in K (see FIG. 6).

[2A-2] Next, by attaching an adhesive tape to the area surrounded by each line on the hard plate 72, two non-bonded sheets 73 are formed in the central portion of the hard plate 72.

More specifically, as shown in FIG. 6, the adhesive tape covers the area surrounded by the lines a, b, e, and f and the area surrounded by the lines c, d, e, and f, respectively. 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, 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 is used. The diagnostic sheet 74 is fixed to the waterproof sheet 20 by joining the edge 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. The constituent inclusions are stored.

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

The joining of the diagnostic sheet 74 and the waterproof sheet 20 and the joining of the diagnostic sheet 74 and the hard plate 72 are performed by, for example, a welding method using a solvent, a heat fusion method of blowing hot air, and an adhesive. It can be carried out by any method such as an adhesive method of joining through, but among them, it is preferably carried out by using a welding method.

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

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

At this time, the non-bonded sheet 73 attached to the central portion of the hard plate 72 functions as a mask for preventing the resin layer located in the region other than the edge portion of the hard plate 72 from coming into contact with the solvent, and as a result, It is possible to reliably prevent the resin layer from being in a molten state.

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

[3A-3] Next, the diagnostic sheet 74 is pressed by a worker or the like to fix 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 provided by the hard plate 72. As a result, the diagnostic sheet 74 is joined to the waterproof sheet 20 and the edge portion (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 74 are not bonded. It is not joined to the sheet 73.

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

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 composed of a resin containing a vinyl chloride resin, for example, Examples thereof include ketones such as tetrahydrofuran (THF) nitrobenzene, carbon tetrachloride, pyridine, ethyl acetate, cyclohexanone and methyl ethyl ketone (MEK), alcohols such as toluene, methyl alcohol and isopropyl alcohol, and one or two of these. The seeds and above can be used in combination, and among them, THF is preferable. THF can surely put the waterproof sheet 20 and the resin layer in a molten state, and since it is a solvent having excellent volatility, the diagnostic sheet 74 and the waterproof sheet 20 and the resin layer can be firmly fixed.

Further, in the adhesive method using an adhesive, an adhesive was applied to the upper surface of the waterproof sheet 20 and the edge of the hard plate 72, and then the diagnostic sheet 74 was attached to the upper surface via the adhesive. After that, the diagnostic sheet 74 is bonded to these by solidifying or curing the adhesive. Therefore, when the adhesive 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 the diagnostic sheet 74, as described above, the waterproof sheet 20 is preferably used. In this case, when the sheet waterproof structure 10 is constructed, the unnecessary portion of the waterproof sheet 20 is prepared by cutting in advance. Will be done.

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

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

The position of the protruding portion 90 is visually recognized while the upper surface of the hard plate 72 is covered with the diagnostic sheet 74. Therefore, a method of obtaining a section from the diagnostic sheet 74 using these protrusions 90 will be described below.

[1B-1] First, a line (inking line) connecting the protruding portions 90 is formed on the diagnostic sheet 74 by using the protruding portion 90 that is visually recognized while the diagnostic sheet 74 follows (covers). ..

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

[1B-2] Next, for 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 along each line using a cutter or the like. By inserting the blade until it reaches 72, the diagnostic sheet 74 is cut (cut) according to the shape of the non-joined sheet 73 located under the diagnostic sheet 74.

At this time, since the diagnostic sheet 74 and the non-joined sheet 73 are not joined at the position corresponding to the non-joined sheet 73 of the diagnostic sheet 74, the diagnostic sheet 74 corresponds to the shape of the non-joined sheet 73. By cutting the above, the section obtained by this cutting can be obtained in a state of being separated from the hard plate 72 (diagnosis unit 70).

By using the protruding portion 90 located on the extension line of each side (4 sides) that determines the outer shape of the non-bonded sheet 73 as in the above steps [1B-1] and [1B-2], The position of the non-bonded sheet 73 arranged on the hard plate 72, that is, the region not joined to the hard plate 72 (inclusion) of the diagnostic sheet 74 can be determined. In other words, the protruding portion 90 can be used as a marker for recognizing the position of the non-bonded sheet 73, that is, the region of the diagnostic sheet 74 that is not bonded to the hard plate 72 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 where it is surely separated from the hard plate 72 (diagnosis unit 70).

Further, when the diagnostic sheet 74 is cut, the blade of the cutter or the like is in contact with the hard plate 72, so that the waterproof sheet 20 located under the hard plate 72 is damaged. Can be accurately prevented.
