Description

[Technical Field]

[0001] The present invention relates to a roof waterproofing panel and a roof waterproofing structure. [Background technology]

[0002] In the exterior structure of a building, a structure in which multiple exterior materials are connected is known. For example, Patent Document 1 discloses that a waterproof structure is formed on a roof or rooftop floor by arranging multiple insulation panels side by side, each insulation panel having a coated metal plate, and gaps between adjacent insulation panels are covered with a waterproof sheet. With this configuration, waterproofing can be ensured even if there are gaps between the insulation panels.

[0003] However, when constructing the waterproof structure described in Patent Document 1 on-site, it is necessary to lay out multiple insulation panels side by side, then unfold the waterproof sheet to cover them, and then thermally fuse the unfolded waterproof sheet to the insulation panels. These operations require a large number of steps. Therefore, the waterproof structure described in Patent Document 1 has the problem of low workability on-site.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The roof waterproof panel and roof waterproof structure of the present invention will be described in detail below with reference to preferred embodiments shown in the accompanying drawings.

[0019] In the following, an example will be described in which the waterproof structure (the waterproof structure of the present invention) is applied to a flat roof.

[0020] 1. Waterproof roof structure FIG. 1 is a partially cross-sectional perspective view showing a roof waterproofing structure 10 according to an embodiment installed on a floor 100. FIG. 2 is a cross-sectional view taken along line AA in FIG. 1. FIG. 3 is an exploded perspective view of a single roof waterproofing panel 1 shown in FIG. 2. In each drawing of the present application, three mutually orthogonal axes, the X-axis, the Y-axis, and the Z-axis, are set, and each axis is indicated by an arrow. The base end of the arrow is referred to as the negative side of each axis, and the tip end is referred to as the positive side of each axis. Furthermore, the positive side of the Z-axis is also referred to as "upper," and the negative side of the Z-axis is also referred to as "lower." In addition, for the sake of convenience, the dimensional ratios of each part in each drawing are different from the actual ratios.

[0021] The waterproof roof structure 10 shown in Figures 1 and 2 is a waterproof structure constructed on a floor 100 (framework) of a flat roof of a building. The waterproof roof structure 10 shown in Figures 1 and 2 comprises a plurality of waterproof roof panels 1 (four in Figure 1) arranged in a matrix along the XY plane on the floor 100. The floor 100 and the plurality of waterproof roof panels 1 form a roof (flat roof).

[0022] The roof waterproofing panel 1 is smaller and lighter than the floor 100, making it easy to transport and install. The roof waterproofing structure 10 can also be installed on various types of structures, such as the floor of a veranda or balcony, instead of the floor 100 of a flat roof.

[0023] The floor section 100 is made of flat plates such as autoclaved lightweight aerated concrete (ALC) panels or extruded cement boards (ECP). These flat plates are joined to a purlin (not shown) that the flat roof is provided with. The floor section 100 may also be made of reinforced concrete, metal floor boards, sheathing boards (wood), etc. The upper surface of the floor section 100 is not limited to a horizontal plane and may be an inclined plane.

[0024] The roof waterproofing structure 10 also includes panel fixing screws 9 (panel fixing devices) shown in Fig. 2. The panel fixing screws 9 are driven into the floor portion 100 to fix the roof waterproofing panel 1 to the floor portion 100. In this way, the roof waterproofing structure 10 is constructed.

[0025] The roof waterproof panel 1 shown in Fig. 2 comprises a waterproof sheet 2, a perforated plate 3, a disk 4, a disk fixing portion 5, and an insulating plate 6. Note that Fig. 2 shows two types of roof waterproof panels 1a and 1b, each having an insulating plate 6 with a different shape.

[0026] The roof waterproof panel 1a is used in a portion that constitutes the flat section of a flat roof. The heat insulating plate 6 provided in the roof waterproof panel 1a has a flat plate shape that extends along the XY plane.

[0027] The waterproof roof panel 1b is used in the area that forms the sloped portion of a flat roof. This sloped portion provides a water gradient to the flat roof. The insulation board 6 provided in the waterproof roof panel 1b has a thickness that varies along the Y-axis direction (height along the Z-axis direction).

[0028] Such a roof waterproof panel 1 can be manufactured in advance in a factory or the like. This allows for efficient manufacturing of roof waterproof panels 1 with stable quality. The manufactured roof waterproof panels 1 can be stacked in the required number and transported to the construction site. This improves transportation efficiency.

[0029] The planar shape (shape as viewed from the Z-axis direction) of the roof waterproof panel 1 shown in Fig. 1 is rectangular. In this case, the planar shapes of the waterproof sheet 2, perforated plate 3, and heat insulating plate 6 that constitute the roof waterproof panel 1 are also rectangular, as shown in Fig. 3. This makes it possible to realize a roof waterproof panel 1 that can be easily laid out in a grid pattern. Note that the planar shape is not limited to a rectangle, and may be, for example, a hexagon or other shape.

[0030] The length L of the roof waterproofing panel 1 in plan view shown in Fig. 3 is not particularly limited, but is preferably 1000 mm or more and 3000 mm or less, and more preferably 1500 mm or more and 2500 mm or less. The width W is also not particularly limited, but is preferably 500 mm or more and 2000 mm or less, and more preferably 700 mm or more and 1500 mm or less. This allows for a roof waterproofing panel 1 that is light enough for workers to carry and has a sufficient area.

[0031] 1.1.Tapering sheet As shown in Fig. 2, the waterproof sheet 2 constitutes the uppermost layer of the roof waterproof panel 1. This provides the roof waterproof structure 10 with excellent waterproofing properties.

[0032] The waterproof sheet 2 is made of a resin sheet whose main material is a resin material, thereby providing a waterproof sheet 2 that is excellent in waterproofness, lightness, and flexibility.

[0033] Examples of resin materials include vinyl chloride resins such as polyvinyl chloride, polyolefin resins, and ethylene-vinyl acetate copolymers, and these can be used alone or in combination. Among these, vinyl chloride resins are preferably used. By using vinyl chloride resins, a waterproof sheet 2 with excellent thermal welding properties and solvent welding properties can be obtained. As a result, when the waterproof sheets 2 of adjacent roof waterproof panels 1 are welded together, a joint 20 with excellent water-stopping properties and durability can be formed.

[0034] The vinyl chloride resin is not particularly limited as long as it is a polymer containing vinyl chloride, i.e., an oligomer, prepolymer, or polymer, but examples thereof include a monomer polymer of vinyl chloride, a copolymer of vinyl chloride with vinyl acetate, ethylene, propylene, or the like, and a mixture of two or more of these.

[0035] The resin material may contain various additives. Examples of additives include plasticizers, stabilizers, antioxidants, UV absorbers, processing aids, lubricants, fillers, flame retardants, and colorants. It is particularly preferable for the resin material to contain a plasticizer. This allows for the waterproof sheet 2 to have excellent flexibility (shape conformability).

[0036] The waterproof sheet 2 may be an asphalt-based sheet, a rubber asphalt-based sheet, a rubber-based sheet, a butyl rubber-based sheet, an acrylic rubber-based sheet, or the like, in addition to a resin sheet.

[0037] The waterproof sheet 2 may have the resin sheet described above and a fiber layer disposed therein. The fiber layer may be any sheet composed of an aggregate of fibers, but examples include cloth such as woven or nonwoven fabric, and netting formed by warp and weft threads forming multiple lattices. The inclusion of such a fiber layer can improve mechanical strength such as tear strength and tensile strength, and durability such as repeated fatigue resistance.

[0038] The thickness of the waterproof sheet 2 is not particularly limited, but is preferably about 0.5 mm to 5.0 mm, and more preferably about 1.0 mm to 2.5 mm, so that the waterproofness of the waterproof sheet 2 can be sufficiently ensured.

[0039] Furthermore, the outer edge of the waterproof sheet 2 may coincide with the outer edge of the perforated plate 3, or may extend in the Y-axis direction relative to the outer edge of the perforated plate 3, as shown in Figure 2. The extending portion 21 of the waterproof sheet 2 is overlaid on the waterproof sheet 2 provided on the adjacent roof waterproof panel 1. This makes it possible to easily and satisfactorily form the joint 20 between the waterproof sheets 2 without preparing a separate member. As a result, it is possible to form the joint 20 with excellent watertightness.

[0040] Although bonding via an adhesive may be used for joining the joint 20, welding such as heat welding or solvent welding is preferably used, which allows the formation of a joint 20 with particularly good water-stopping properties and bonding strength.

[0041] Although not shown, the outer edge of the waterproof sheet 2 may extend in the X-axis direction, or may extend in both the X-axis and Y-axis directions.

[0042] Furthermore, all four sides of the rectangular waterproof sheet 2 may be extended, but taking into consideration the compatibility of the waterproof sheets 2 with each other, only some of the sides may be extended and the remaining sides may not be extended.

[0043] The extension length of the extension portion 21 is not particularly limited, but is preferably 50 mm or more, and more preferably 80 mm or more, thereby forming a joint portion 20 that has sufficient width and excellent watertightness.

[0044] The upper limit of the extension length does not need to be set in particular, but it is preferably 200 mm or less in order to avoid a decrease in workability and an increase in weight due to the joint 20 becoming too wide.

[0045] In addition, if the outer edge of the waterproof sheet 2 does not extend, another piece of waterproof sheet can be placed in the gap between the waterproof sheets 2 and welded.

[0046] 1.2.Perforated plate The perforated plate 3 is disposed below the waterproof sheet 2 .

[0047] As shown in FIG. 3 , the perforated plate 3 has a plate shape extending along the XY plane. The perforated plate 3 also has a plurality of through holes 31 penetrating in the Z-axis direction and a plurality of panel fixing screw holes 32. As shown in FIG. 2 , a portion of a receiving seat 51 of the disk fixing portion 5 is inserted into the through hole 31. This makes it possible to easily regulate the position of the receiving seat 51 relative to the perforated plate 3. As shown in FIG. 2 , a disk fixing screw 52 of the disk fixing portion 5 is inserted into the through hole 31. This disk fixing screw 52 is inserted into the hole 41 formed in the disk 4 and the through hole 31 formed in the perforated plate 3 and is screwed into the receiving seat 51. This connects the disk 4 and the receiving seat 51 via the through hole 31 and also makes it possible to regulate the position of the disk 4 relative to the perforated plate 3. As a result, the perforated plate 3, the disk 4, and the disk fixing portion 5 are connected to the heat insulating plate 6.

[0048] The arrangement density of the through holes 31 is not particularly limited, but is preferably two or more per square meter, and more preferably four or more. This allows the disks 4 to be arranged with sufficient density. As a result, the adhesive strength between the waterproof sheet 2 and the disks 4 can be sufficiently ensured.

[0049] There is no particular upper limit to the density of the through holes 31, but taking into consideration the reduction in workability and the reduction in the mechanical strength of the perforated plate 3, it is preferably set to 10 or less per square meter.

[0050] The arrangement pattern of the through holes 31 shown in FIG. 3 is a matrix pattern with arrangement axes parallel to the X-axis and Y-axis, but is not limited to this and may be any pattern.

[0051] 2, a panel fixing screw 9 is inserted into the panel fixing screw hole 32. This panel fixing screw 9 is inserted into the panel fixing screw hole 32, penetrates the heat insulating board 6, and is driven into the floor portion 100.

[0052] The arrangement density of the panel fixing screw holes 32 is set appropriately depending on the required wind pressure resistance. The arrangement pattern of panel fixing screw holes 32 shown in FIG. 3 is a matrix pattern with arrangement axes parallel to the X-axis and Y-axis, but is not limited to this and may be any pattern.

[0053] As shown in Fig. 3, printing 33 indicating the appropriate length of the disk fixing screw 52 or panel fixing screw 9 may be provided near the through hole 31 or the panel fixing screw hole 32. In the example of Fig. 3, the text "140" is printed near the through hole 31. In this case, the installer can be informed in an easy-to-understand manner that the appropriate length of the disk fixing screw 52 is 140 mm. The content of the notification is not limited to the screw length, and other information may be used.

[0054] Examples of the perforated board 3 include various cement boards such as calcium silicate board, pulp-mixed cement board, slag gypsum board, hard wood chip cement board, and fiber-mixed slate board, and various wood boards such as plywood, particle board, MDF, OSB, hardboard, CLT, laminated wood, and resin wood. The perforated board 3 may have a surface material that covers the surface of the board.

[0055] The perforated plate 3 is preferably made of a material having higher rigidity than the heat insulating plate 6. This makes it possible to suppress deformation of the heat insulating plate 6 and the like.

[0056] The thickness of the perforated plate 3 is not particularly limited, but is preferably about 3 mm or more and 20 mm or less, and more preferably about 5 mm or more and 15 mm or less. This ensures sufficient rigidity of the perforated plate 3 and prevents the roof waterproof panel 1 from becoming heavy.

[0057] 1.3.Disk As shown in FIG. 2, the disk 4 is disposed between the waterproof sheet 2 and the perforated plate 3. The disk 4 is adhered to the waterproof sheet 2. The disk 4 and the waterproof sheet 2 may be adhered to each other via an adhesive or the like, but are preferably adhered by welding. Welding refers to a bonding method in which at least one of the disk 4 and the waterproof sheet 2 is melted and integrated with each other. Examples of welding include heat welding and solvent welding. Welding particularly enhances the adhesive strength and durability between the disk 4 and the waterproof sheet 2.

[0058] The above-mentioned bonding is performed in advance in a factory, etc., which improves work efficiency. As a result, there is no need to perform the above-mentioned bonding at the construction site of the roof waterproofing structure 10, which reduces the number of construction steps and construction costs.

[0059] It is preferable that while a portion of the waterproof sheet 2 is adhered to the disk 4, the other portion is not fixed to any other member and is free, at least before construction. This allows the waterproof sheet 2 to be rolled up, making it easy to insert the panel fixing screws 9 into the panel fixing screw holes 32 when constructing the roof waterproof panel 1.

[0060] The disk 4 is preferably a member that generates heat through electromagnetic induction. This allows the disk 4 to be heated from above the waterproof sheet 2, and the waterproof sheet 2 and the disk 4 to be thermally welded together. Therefore, providing the disk 4 can improve the manufacturing efficiency of the roof waterproof panel 1. Note that the disk 4 and the waterproof sheet 2 may be solvent-welded instead of thermally welded.

[0061] The disk 4 is made of, for example, a resin-coated steel plate having a core material and a resin layer that coats the core material. When the core material generates heat due to indirect heating, the resin layer and the waterproof sheet 2 can be fused together by the heat.

[0062] Examples of the core material include stainless steel plate, as well as rust-proof steel plate such as zinc-aluminum-magnesium plated or zinc plated. Examples of materials constituting the resin layer include vinyl chloride resin, hot-melt resin, etc.

[0063] The shape of the disk 4 in plan view is not particularly limited, but examples include circles such as perfect circles and ellipses, polygons such as squares, rectangles, and hexagons, and other shapes.

[0064] 3 has a hole 41 penetrating in the Z-axis direction. A disk fixing screw 52 is inserted into this hole 41. This regulates the position of the disk 4 relative to the perforated plate 3.

[0065] The outer diameter of the disk 4 is not particularly limited, but is preferably 20 mm or more and 150 mm or less, and more preferably 30 mm or more and 100 mm or less, from the viewpoint of ensuring sufficient adhesive strength with the waterproof sheet 2 and suppressing the weight of the roof waterproof panel 1. The outer diameter of the disk 4 refers to the maximum length that can be obtained when viewed in a plane.

[0066] The thickness of the disk 4 is not particularly limited, but taking into consideration the effect on the flatness of the upper surface of the waterproof sheet 2 and mechanical strength, etc., it is preferable that it be approximately 0.3 mm or more and 2 mm or less, and more preferably approximately 0.6 mm or more and 1 mm or less.

[0067] 1.4.Disc fixing part As described above, the disk fixing portion 5 has the receiving seat 51 and the disk fixing screw 52.

[0068] The receiving seat 51 is provided below the perforated plate 3 (on the opposite side to the disk 4). As shown in Fig. 3, the receiving seat 51 has a plate-shaped flat portion 512, a protruding portion 514 that protrudes from the main surface of the flat portion 512 and is inserted into the through hole 31 of the perforated plate 3, and a disk fixing screw hole 516 that passes through these and screws into which the disk fixing screw 52 is threaded.

[0069] The flat plate portion 512 is in the form of a plate having two main surfaces that are opposite each other. Each main surface is set large enough to encompass the opening of the through hole 31. As a result, when the receiving seat 51 is positioned to match the through hole 31, the flat plate portion 512 is not inserted into the through hole 31 and remains between the perforated plate 3 and the heat insulating plate 6. As a result, the perforated plate 3 can be sandwiched between the disk 4 and the receiving seat 51.

[0070] The flat plate portion 512 may simply be placed on the heat insulating plate 6, or may be adhered thereto. This prevents misalignment between the heat insulating plate 6 and the flat plate portion 512 before the disk fixing screws 52 are driven in. As a result, the efficiency of the work of driving the disk fixing screws 52 is improved.

[0071] The shape of the flat plate portion 512 in a plan view is not particularly limited, and may be a polygon such as a square, rectangle, or hexagon, or may be another shape, in addition to the circle shown in Fig. 3. Note that in Fig. 2 and other figures, the flat plate portion 512 is buried in the perforated plate 3 for convenience of illustration. Although the flat plate portion 512 may actually be buried in the perforated plate 3, it is preferable that it is outside the perforated plate 3 from the viewpoint of being less likely to affect the mechanical strength of the perforated plate 3.

[0072] The protrusion 514 protrudes from one main surface of the flat plate portion 512 and is inserted into the through-hole 31 as shown in FIG. 2. This makes it easy to regulate the position of the receiving seat 51 relative to the through-hole 31. Furthermore, with the above configuration, the distance between the disk 4 and the receiving seat 51 can be maintained constant. This prevents the perforated plate 3 from being crushed even when the disk fixing screw 52 is tightened too much.

[0073] The protruding height h of the protruding portion 514 shown in Fig. 2 is not particularly limited, and may be higher than the thickness of the perforated plate 3, but is preferably equal to or less than the thickness of the perforated plate 3. This allows the perforated plate 3 to be securely clamped between the disk 4 and the receiving seat 51. If the protruding height h is significantly lower than the thickness of the perforated plate 3, the perforated plate 3 may be more susceptible to damage depending on the tightening torque of the disk fixing screw 52. From this perspective, the protruding height h is preferably 50% to 100% of the thickness of the perforated plate 3, and more preferably 70% to 100%.

[0074] The disk fixing screw hole 516 penetrates the flat plate portion 512 and the protruding portion 514 in the Z-axis direction. An internal thread is provided on the inner peripheral surface of the disk fixing screw hole 516. This internal thread is threadedly engaged with the disk fixing screw 52. This integrates the perforated plate 3, disk 4, and disk fixing portion 5. The disk fixing screw 52 also penetrates the receiving seat 51 while threadedly engaging with the disk fixing screw hole 516, and is then driven into the heat insulating plate 6. This integrates the perforated plate 3, disk 4, disk fixing portion 5, and heat insulating plate 6. Note that the threaded engagement between the disk fixing screw hole 516 and the disk fixing screw 52 may be replaced by another engagement structure. An example of another engagement structure is a structure in which they are hooked together using an elastic member.

[0075] 1.5.Insulating board The heat insulating board 6 constitutes the bottom layer of the roof waterproof panel 1. This provides heat insulation to the flat roof.

[0076] The roof waterproofing panel 1 shown in Figure 2 has two layers of insulating boards 6 stacked on top of each other. This provides the necessary insulating performance to a flat roof. In other words, it is possible to realize a roof waterproofing panel 1 in which the insulating boards 6 can be installed and waterproofed on top of them simultaneously.

[0077] The number of layers of insulating plates 6 provided in the roof waterproofing panel 1 is not particularly limited, and may be one layer or three or more layers. When multiple insulating plates 6 are provided, the insulating plates 6 are bonded together, for example, with an adhesive. Note that the roof waterproofing panel 1 may be one in which the insulating plates 6 are omitted, taking into consideration the possibility of assembling the insulating plates 6 at a construction site, etc. In this case, instead of driving the disk fixing screws 52 into the insulating plates 6, the insulating plates 6 may be connected to at least one of the disk fixing portion 5 and the perforated plate 3 via another member, for example, an adhesive or adhesive tape.

[0078] Furthermore, when two or more layers of heat insulating plates 6 are used, the flat area and the sloped area can be easily formed by changing the upper heat insulating plate 6.

[0079] For example, the above-mentioned roof waterproof panel 1b is provided with a gradient heat insulating plate 6b whose thickness varies along the Y-axis direction, as shown in Figure 2. The water gradient can be easily adjusted depending on the shape of the gradient heat insulating plate 6b.

[0080] The heat insulating board 6 is made of a resin foam such as polystyrene foam, polyurethane foam, or polyethylene foam.

[0081] The heat insulating board 6 may also have a surface material that covers the surface of the resin foam. Examples of the surface material that can be used include various steel plates such as Galvalume steel plate (registered trademark) and stainless steel plate. By providing the surface material, the heat insulating board 6 is endowed with environmental resistance (anti-corrosion properties).

[0082] The total thickness of the heat insulating boards 6 is set appropriately depending on the required heat insulating performance, but is preferably 10 mm or more and 300 mm or less, and more preferably 30 mm or more and 100 mm or less.

[0083] The gradient of the gradient heat insulating board 6b is preferably 1 / 20 or more and 1 / 100 or less, and more preferably 1 / 30 or more and 1 / 60 or less, thereby providing good drainage properties to the flat roof.

[0084] 1.6.Panel Fixtures 2 is inserted into the panel fixing screw hole 32, penetrates the heat insulating board 6, and is driven into the floor part 100. This allows the roof waterproof panel 1 to be fixed to the floor part 100.

[0085] The panel fixing screws 9 may be replaced with other fixing devices such as bolts and nuts, anchor bolts, clips, etc.

[0086] 2. Manufacturing method of roof waterproofing panels Next, a description will be given of an example of a method for manufacturing the roof waterproof panel 1. Note that the method for manufacturing the roof waterproof panel 1 is not limited to the following method, and other methods may also be used. 4 to 7 are cross-sectional views showing a method for manufacturing the roof waterproof panel 1.

[0087] First, as shown in FIG. 4, the receiving seat 51 is adhered to the upper surface of the heat insulating plate 6. 5, the perforated plate 3 is placed on the upper surface of the heat insulating plate 6. Then, the protrusions 514 of the receiving seats 51 are inserted into the through holes 31 of the perforated plate 3.

[0088] 6, the disk 4 is placed on the upper surface of the perforated plate 3. Then, the disk fixing screw 52 is driven into the heat insulating plate 6 so as to penetrate the disk 4 and screw into the receiving seat 51.

[0089] Next, as shown in Fig. 7, the waterproof sheet 2 is placed on the upper surface of the perforated plate 3 so as to cover the disk 4. Then, the disk 4 and the waterproof sheet 2 are adhered together. In this way, the roof waterproof panel 1 is obtained.

[0090] Each of the above steps can be carried out in a factory, etc. Therefore, compared to when each step is carried out at a construction site, the roof waterproof panel 1 can be manufactured efficiently with stable quality.

[0091] If necessary, the manufactured roof waterproofing panel 1 may be fastened with a band. This prevents the components from separating or falling off. Bands used for fastening the bands may be, for example, PP bands (polypropylene bands) or other string-like members.

[0092] 3. How to install roof waterproofing panels Next, a method for installing the roof waterproofing panel 1 (a method for manufacturing the roof waterproofing structure 10) will be described. 8 and 9 are cross-sectional views showing a method for installing the roof waterproof panel 1. FIG.

[0093] First, the roof waterproof panel 1 manufactured in a factory or the like is carried to the construction site and placed on the floor 100 (framework) shown in Fig. 8. By arranging multiple roof waterproof panels 1, the floor 100 can be covered with the roof waterproof panels 1 regardless of the size of the floor 100.

[0094] Next, as shown in Figure 8, the waterproof sheet 2 is rolled up to expose the panel fixing screw holes 32. Then, the panel fixing screws 9 are inserted into the panel fixing screw holes 32 and driven into the floor part 100. This allows the roof waterproof panel 1 to be fixed to the floor part 100.

[0095] Next, as shown in Fig. 9, the waterproof sheets 2 provided on adjacent roof waterproof panels 1 are joined together. In the example shown in Fig. 9, three roof waterproof panels 1 are adjacent to each other. Then, the extension portion 21 of the waterproof sheet 2 provided on one roof waterproof panel 1 is overlapped and joined to the waterproof sheet 2 provided on another roof waterproof panel 1. As a result, a joint 20 shown in Fig. 9 is obtained at the boundary between adjacent roof waterproof panels 1.

[0096] In this way, the construction of the roof waterproof panel 1 is completed, and the roof waterproof structure 10 is obtained. At the boundary portions, the waterproof sheets 2 of adjacent roof waterproof panels 1 may be joined together by overlapping and welding another waterproof sheet piece (not shown).

[0097] 4. Variations Next, a roof waterproofing structure 10 according to a modified example will be described.

[0098] The following describes a roof waterproofing structure 10 according to a modified example, but the following explanation focuses on the differences from the roof waterproofing structure 10 according to the above-described embodiment, and omits a description of similar points. In the following drawings, the same reference numerals are used to designate the same components as those in the above-described embodiment.

[0099] FIG. 10 is a cross-sectional view showing a roof waterproofing structure 10 according to a first modified example. The skeleton shown in Fig. 10 has a floor section 100 and a wall section 200 rising from the end of the floor section 100. The wall section 200 is, for example, a parapet (spandrel wall).

[0100] The roof waterproofing structure 10 shown in Figure 10 comprises the above-mentioned roof waterproofing panel 1 and panel fixing screws 9, a wall member 71 that covers the top and side surfaces of the wall member 200, and an inside corner member 72 that connects the waterproof sheet 2 and the wall member 71.

[0101] With this configuration, good water-stopping properties can be efficiently imparted to the joint between the roof waterproofing panel 1 and the wall portion 200. Therefore, with this configuration, even when the skeleton has the wall portion 200, a roof waterproofing structure 10 with good workability and water-stopping properties can be realized.

[0102] The wall member 71 and the inside corner member 72 are each made of a resin-coated member having, for example, a core material and a resin layer covering the core material. Examples of the core material include stainless steel plate, steel plate that has been subjected to rust prevention treatment such as zinc-aluminum-magnesium plating or zinc plating, and resin base material made of hard polyvinyl chloride resin. Examples of materials that can be used for the resin layer include polyvinyl chloride resin and hot-melt resin.

[0103] The inside corner component 72 may also be a laminate of a resin-coated component molded into a predetermined shape and a waterproof sheet piece layered over it. This laminate has the waterproof sheet piece already attached, which contributes to improving workability when connecting the waterproof sheet 2 and the wall component 71, as shown in Figure 10. In consideration of workability, it is preferable that the outer edge of the waterproof sheet piece in the laminate already extends beyond the outer edge of the resin-coated component.

[0104] The joints between the wall member 71 and the inside corner member 72, and the joints between the waterproof sheet 2 and the inside corner member 72 are joined by, for example, heat welding or solvent welding.

[0105] 11 is a cross-sectional view showing a roof waterproofing structure 10 according to the second modified example. In the following explanation, the same matters as those in the first modified example will not be explained again.

[0106] 11 includes the above-mentioned roof waterproofing panel 1, panel fixing screws 9, a wall member 71, and a rising member 73. The rising member 73 connects the waterproof sheet 2 and the wall member 71.

[0107] With this configuration, good water-stopping properties can be efficiently imparted to the joint between the roof waterproofing panel 1 and the wall portion 200. Therefore, with this configuration, even when the skeleton has the wall portion 200, a roof waterproofing structure 10 with good workability and water-stopping properties can be realized.

[0108] The rising member 73 is made of the resin-coated member described above, or a laminate of a resin-coated member and a waterproof sheet piece. The rising member 73 shown in Fig. 11 is inserted between the perforated plate 3 of the roof waterproof panel 1 and the waterproof sheet 2. The underside of the waterproof sheet 2 is then joined to the rising member 73. This makes it possible to more reliably prevent water leakage at the joint.

[0109] The joints between the wall members 71 and the rising members 73, and the joints between the waterproof sheet 2 and the rising members 73 are joined by, for example, heat welding or solvent welding.

[0110] 12 is a cross-sectional view showing a roof waterproofing structure 10 according to a third modified example. In the following explanation, the same matters as those in the first modified example will not be explained again.

[0111] The roof waterproofing structure 10 shown in Fig. 12 comprises the above-mentioned roof waterproofing panel 1 and panel fixing screws 9, a wall member 71, and a base member 74. The base member 74 is disposed between the perforated plate 3 and the waterproof sheet 2, and is fixed to the perforated plate 3 by the panel fixing screws 9. In addition, the extension portion 21 of the waterproof sheet 2 provided in the roof waterproofing panel 1 shown in Fig. 12 is joined to the wall member 71.

[0112] With this configuration, good water-stopping properties can be efficiently imparted to the joint between the roof waterproofing panel 1 and the wall portion 200. Therefore, with this configuration, even when the skeleton has the wall portion 200, a roof waterproofing structure 10 with good workability and water-stopping properties can be realized.

[0113] In addition, the waterproof sheet 2 is joined to the base member 74. This allows the waterproof sheet 2 to be fixed well, and the wind pressure resistance of the roof waterproofing structure 10 can be improved.

[0114] The joint between the waterproof sheet 2 and the base member 74, and the joint between the waterproof sheet 2 and the wall member 71 are joined by, for example, heat welding or solvent welding.

[0115] 13 is a cross-sectional view showing a roof waterproofing structure 10 according to a fourth modified example. In the following explanation, the same matters as those in the third modified example will not be explained again.

[0116] The roof waterproofing structure 10 shown in Fig. 13 includes the above-mentioned roof waterproofing panel 1, panel fixing screws 9, and a wall member 71. The extension portion 21 of the waterproof sheet 2 included in the roof waterproofing panel 1 shown in Fig. 13 is joined to the wall member 71. In other words, the roof waterproofing structure 10 shown in Fig. 13 is the same as the roof waterproofing structure 10 shown in Fig. 12 except that the base member 74 is omitted.

[0117] With this configuration, good water-stopping properties can be efficiently imparted to the joint between the roof waterproofing panel 1 and the wall portion 200. Therefore, with this configuration, it is possible to realize a roof waterproofing structure 10 with good workability and water-stopping properties even when the skeleton has the wall portion 200. Furthermore, in the fourth modified example, the number of components is smaller than in the third modified example, and therefore the workability of the roof waterproofing structure 10 can be improved.

[0118] 5. Effects of the above embodiment and the above modification The roof waterproof panel 1 according to the embodiment and the modified example is a roof waterproof panel that is laid in a row on a floor 100 (structure) to form a roof on the floor 100 (structure), and comprises a waterproof sheet 2, a perforated plate 3, a disk 4, and a disk fixing part 5. The perforated plate 3 has a plurality of through holes 31. The disk 4 is provided between the waterproof sheet 2 and the perforated plate 3 and is adhered to the waterproof sheet 2. The disk fixing part 5 fixes the disk 4 to the perforated plate 3.

[0119] In this configuration, the waterproof sheet 2 is pre-bonded to the disk 4. This eliminates the need to bond the waterproof sheet 2 and disk 4 at the construction site. This reduces the number of man-hours required at the construction site, resulting in a roof waterproof panel 1 that is highly workable. Furthermore, the above-mentioned roof waterproof panel 1 can be easily mass-produced in a factory, etc. This allows for a roof waterproof panel 1 with stable quality to be obtained.

[0120] In the roof waterproofing panels 1 according to the above-described embodiment and the above-described modified examples, the disk fixing portion 5 has a receiving seat 51 and a disk fixing screw 52. The receiving seat 51 is provided on the side of the perforated plate 3 opposite the disk 4. The disk fixing screw 52 penetrates the disk 4 in the thickness direction, is inserted into the through-hole 31 of the perforated plate 3, and is screwed into the receiving seat 51.

[0121] According to this configuration, the disc 4 and the receiving seat 51 are connected via the through-hole 31, and the position of the disc 4 relative to the perforated plate 3 can be regulated.

[0122] In the roof waterproofing panel 1 according to the embodiment and the modified example, the receiving seat 51 has a flat plate portion 512, a protruding portion 514, and a disk-fixing screw hole 516. The flat plate portion 512 is plate-shaped. The protruding portion 514 protrudes from the main surface of the flat plate portion 512. The disk-fixing screw hole 516 penetrates the flat plate portion 512 and the protruding portion 514. With the protruding portion 514 inserted into the through-hole 31, the disk-fixing screw 52 screws into the disk-fixing screw hole 516.

[0123] With this configuration, the position of the receiving seat 51 relative to the through-hole 31 can be easily regulated. Furthermore, by inserting the protrusion 514 into the through-hole 31, the distance between the disk 4 and the receiving seat 51 can be maintained constant. This prevents the perforated plate 3 from being crushed even when the disk fixing screw 52 is tightened too tightly.

[0124] In the roof waterproofing panels 1 according to the above-described embodiment and the above-described modified examples, the disk 4 includes a material that generates heat by electromagnetic induction.

[0125] According to this configuration, the disk 4 can be heated from above the waterproof sheet 2, and the waterproof sheet 2 and the disk 4 can be thermally welded together. Therefore, by providing the disk 4, the manufacturing efficiency of the roof waterproof panel 1 can be improved.

[0126] In the roof waterproof panel 1 according to the embodiment and the modified example, the waterproof sheet 2 is welded to the disk 4.

[0127] According to this configuration, the adhesive strength and durability between the disk 4 and the waterproof sheet 2 are particularly improved by welding.

[0128] In the roof waterproof panel 1 according to the embodiment and the modified example, the waterproof sheet 2 extends from the outer edge of the perforated plate 3 when viewed from above.

[0129] According to this configuration, the waterproof sheets 2 of adjacent roof waterproof panels 1 can be easily overlapped with each other, and a joint 20 can be obtained by welding the waterproof sheets 2 together without using any additional member.

[0130] The roof waterproof panel 1 according to the embodiment and the modified example further includes a heat insulating plate 6 provided on the side of the perforated plate 3 opposite to the waterproof sheet 2 .

[0131] This configuration can provide thermal insulation to a roof constructed using the roof waterproofing panel 1. In other words, it is possible to realize a roof waterproofing panel 1 that allows the installation of the insulating board 6 and the application of waterproofing treatment thereon to be performed simultaneously.

[0132] In the roof waterproofing panels 1 according to the above-described embodiment and the above-described modified examples, the disk fixing portion 5 and the heat insulating plate 6 are bonded together.

[0133] This configuration can prevent misalignment between the heat insulating plate 6 and the disk fixing portion 5. This improves work efficiency when, for example, driving the disk fixing screws 52 to finally fix the disk fixing portion 5.

[0134] The roof waterproofing structure 10 according to the embodiment and the modified example is a roof waterproofing structure provided on a floor 100 (framework), and includes a plurality of roof waterproofing panels 1 and panel fixing screws 9 (panel fixing devices). The roof waterproofing panels 1 are arranged along the floor 100. The panel fixing screws 9 fix the roof waterproofing panels 1 to the floor 100. The waterproof sheets 2 provided on adjacent roof waterproofing panels 1 are joined together.

[0135] According to this configuration, the waterproof sheet 2 and the disk 4 are pre-bonded in the roof waterproof panel 1, eliminating the need for the work of bonding the waterproof sheet 2 and the disk 4 at the construction site. This reduces the number of steps at the construction site and provides a roof waterproof structure 10 that is highly workable. Furthermore, the above-mentioned roof waterproof panel 1 can be easily mass-produced in a factory, etc. This allows for a roof waterproof structure 10 with stable quality to be obtained.

[0136] In the roof waterproofing structure 10 according to the embodiment and the modified example, the skeleton has a floor portion 100 and a wall portion 200 rising from the end of the floor portion 100. The roof waterproofing panels 1 are arranged on the floor portion 100. Furthermore, the roof waterproofing structure 10 includes a wall member 71 installed on the wall portion 200. The waterproof sheet 2 is joined to the wall portion 200 via the wall member 71.

[0137] With this configuration, good water-stopping properties can be efficiently imparted to the joint between the roof waterproofing panel 1 and the wall portion 200. Therefore, with this configuration, even when the skeleton has the wall portion 200, a roof waterproofing structure 10 with good workability and water-stopping properties can be realized.

[0138] Although the roof waterproofing panel and the roof waterproofing structure of the present invention have been described above, the present invention is not limited to these.

[0139] For example, the roof waterproofing panel and roof waterproofing structure of the present invention may be such that each configuration of the above-mentioned embodiment or modified example is replaced with any configuration that can perform the same function, or such that any configuration is added to the above-mentioned embodiment or modified example.

[0140] Furthermore, the roof waterproofing panel and roof waterproofing structure of the present invention may have a configuration that combines two or more of the above-described embodiments and modifications. [Explanation of symbols]
