Fig. 4 is a plan view showing the configuration of the uneven panel. Figs. 5 to 8 are cross-sectional views of a part of the roof structure. Fig. 9 is a perspective view of the roof material, and Fig. 10 is a perspective view of the fastener. Figs. 11 and 12 are explanatory views of the connection part between the panel-attached roof material and the base roof material. Figs. 13 to 15 are explanatory views showing the installation method of the roof material, and Fig. 16 is an explanatory view of the arrangement of the roof material. Figs. 17 to 21 are explanatory views showing an example of the construction of the roof material. In each figure, the configuration is appropriately enlarged, reduced, or omitted for the purpose of explanation.

[0018] As shown in Figures 1 to 8, the roof structure 1 has a ridge 11, an eaves 12, and a gable 13, and forms an inclined portion 10 extending along a predetermined inclination direction from the ridge 11 to the eaves 12. For example, the roof structure 1 forms inclined portions 10 on one side and on the other side via the ridge 11. Each inclined portion 10 is surrounded by the ridge 11 at the upper end and the eaves 12 at the lower end, and the gable 13 on both edges.

[0019] The roof structure 1 comprises, at each inclined portion 10, a sheathing board 110, an underlayment material 120, a concave-convex panel material 125 which is a roof panel material, a plurality of base roof materials 130, and a plurality of panel-attached roof materials 150. The roof structure 1 further comprises components such as an eaves edge water drain 170, a gable water drain 180, a ridge 220, and a coping board. The roof structure 1 may also have other components such as a heat shield sheet, a ventilation material, or waterproof paper between the sheathing board 110 and the roof material 130 or the panel-attached roof material 150.

[0020] In addition, the roof structure 1 further includes a plurality of terminal boxes 158 disposed on the rear sides of the plurality of panel roof materials 150, respectively, and a plurality of cables 157 connected to the plurality of terminal boxes 158.

[0021] The sheathing board 110 is formed of, for example, structural plywood. The sheathing board 110 is fastened to the rafters with nails or the like. The sheathing board 110 may be made of MDF (Medium Density Fiberboard), particle board, OSB (Oriented Strand Board), or may be a single board material such as solid cedar. The sheathing board 110 is disposed on the back side of the roof materials 130, 150.

[0022] The underlayment material 120 is a so-called roofing sheet having waterproof properties. For example, the underlayment material 120 is formed by impregnating and / or applying asphalt to a base material. The underlayment material 120 is fastened to the sheathing board 110, for example. As a specific example, the underlayment material 120 is provided on the top board of the sheathing board 110.

[0023] The sheathing board 110 and the underlayment material 120 may have openings formed therein for pulling in the cables 157 arranged on the back side of the roof material 150 into the building.

[0024] The multiple roof materials 130, 150 are arranged in multiple rows in a first direction, which is the inclination direction (vertical direction) of the sheathing board 110 from the ridge 11 toward the eaves 12, and a second direction, which is the width direction (horizontal direction) perpendicular to or intersecting the first direction.

[0025] The multiple roof materials 130, 150 are partially stacked in a sloping direction (first direction) from the ridge 11 toward the eaves 12, and are fastened to the sheathing boards 110 to which the underlayment material 120 is fastened by fastening members such as screws or nails.

[0026] The multiple roofing materials 130, 150 include, for example, multiple types of roofing materials 130, 150 with different configurations. As an example, in this embodiment, the roofing material 150 includes multiple panel-mounted roofing materials 150 having solar panels integrally formed on their surfaces, and a surrounding base roofing material 130 disposed around the multiple panel-mounted roofing materials 150.

[0027] In this embodiment, as an example, multiple types of roof materials 130, 150 are arranged, with the panel roof material 150 arranged in the central region in the tilt direction, and the base roof material 130 arranged at both end edges in the tilt direction and lateral direction. In the roof structure 1, the multiple roof materials 130, 150 lined up in the tilt direction are connected to each other by engagement via fasteners 160 or by engagement by a return structure.

[0028] In the roof structure 1, the multiple roof materials 130, 150 have the ridge-side edge portion of the top plate 131, 151 of the roof material 130, 150 on the eaves side covered by another roof material 130, 150 adjacent to the ridge side.

[0029] For example, in this embodiment, as an example, the roof structure 1 has a connection structure A1 between the base roof material 130 and the panel roof material 150, a connection structure A2 between the panel roof materials 150, and a connection structure A3 between the panel roof material and the base roof material 130, as shown in FIG. 5, as a connection structure in which the roof materials are connected in the inclination direction, which is the first direction. In addition, depending on the number of rows of the roof material 130, a connection structure A4 between the base roof materials 130 may be further provided. For example, the connection structures A2 and A3 are connection structures using a fastener 160, and the connection structures A1 and A4 are connection structures using a return structure. Note that FIG. 1 illustrates a configuration in which there is only one row of base roof material 130 on the eaves side and there is no connection structure A4 on the eaves side, but when there are multiple rows of base roof material 130, a connection structure A4 is provided as shown in FIG. 5.

[0030] For example, in this embodiment, as an example, the roof structure 1 has a connection structure A5 in which the edges of adjacent roof materials 130, 150 in the second direction are overlapped and connected by a joining member such as an adhesive tape, as shown in Fig. 9, as a connection structure for connecting roof materials in the second direction. For example, in each of the roof materials 130, 150, the edge portion in the second direction may be partially cut off to adjust the width dimension in the second direction, or other end treatment may be performed.

[0031] For example, the roof materials 130 and 150 are horizontal roof materials made of metal sheets, and are formed by bending steel sheets having a thickness of about 0.35 mm to 0.40 mm.

[0032] The base roof material 130 is integrally composed of a top plate 131, side plates 132, and a bottom plate 133.

[0033] Base roof material 130 is formed by bending a steel plate having a thickness of, for example, about 0.35 mm to 0.40 mm, so that top plate 131, side plate 132, and bottom plate 133 are integrally formed. For example, base roof material 130 configures return structure 135 that covers the lower end side of fastener 160 by side plate 132 and bottom plate 133 that are bent at two points from the end of top plate 131 on the eaves 12 side.

[0034] The top plate 131 is configured in a plate shape having a predetermined width and depth, and covers the front side of the sheathing board 110 and the underlayment material 120. The top plate 131 is set to a length that covers a part of the top plates 131, 151 of another panel-attached roof material 150 or roof material 130 that is lined up on the eaves side in the first direction.

[0035] A ridge-side edge 131a of the top plate 131 has a ridge-side structural part 131d at a predetermined location a predetermined distance away from the ridge-side edge 131a, which protrudes toward the front side and is bent toward the eaves side to extend toward the eaves side. The ridge-side structural part 131d forms a gap 131c into which the bottom plate 133, 153 of another roof member 130 or roof member 150 adjacent to the ridge side is inserted, and holds the ridge-side structural parts 135, 155 by engaging with the ridge-side structural parts 131d. As an example, the ridge-side structural part 131d is formed at a position a predetermined distance toward the eaves side from the ridge-side edge 131a of the top plate 131.

[0036] The top plate 131 is fastened to the sheathing board 110 at a predetermined location between the return structure portion 131d and the edge 131a by fastening members 165 such as screws.

[0037] A heat insulating member 139 is provided on the back side of the top board 131, that is, on the surface facing the sheathing board 110. The heat insulating member 139 is bonded to the back side of the top board 131, for example, in an area excluding the edge portion where the side board 132 is arranged. The heat insulating member 139 has a thickness smaller than the gap formed between the sheathing board 110, and the thickness may vary depending on the portion. In general, the heat insulating member 139 is configured to be thinner on the water surface (ridge side). For example, the thickness can be adjusted by the arrangement of the convex portion 125b of the uneven panel 125. For example, as shown in FIG. 17, the thickness dimension and the gap dimension can be adjusted by removing some of the convex portions 125b and deforming the top board 131.

[0038] The side plate 132 is integrally connected to the top plate 131 and the bottom plate 133. The side plate 132 is disposed on the eaves side of the return structure 131d of the other roof material 130 provided on the lower tier, or on the eaves side of the pressing piece 163 of the fastener 160 fastened to the other roof material 150 provided on the lower tier.

[0039] The width dimension of the side panel 132 is set to, for example, the same dimension as the width dimension of the top panel 131. The side panel 132 is disposed on the eaves 12 side of the top panel 131. As an example, the side panel 132 intersects or is perpendicular to a surface along the surface direction of the top panel 131 and the top panel 131.

[0040] The bottom plate 133 is set parallel or nearly parallel to the top plate 131. The distance between the top plate 131 and the bottom plate 133 is configured so that the pressing piece 163 of the fixing device 160 can be arranged. The width dimension of the bottom plate 133 is set to be the same as the width dimension of the top plate 131. The depth dimension of the bottom plate 133 is set to be shorter than the depth dimension of the top plate 131. More specifically, the depth dimension of the bottom plate 133 is set to be a dimension that is closer to the eaves side than the ridge-side end of the top plates 131, 151 of another roof material 130 or panel-attached roof material 150 adjacent below.

[0041] Here, the depth refers to the direction of the underwater (eaves 12) side and the abovewater (ridge 11) side of the roof structure 1.

[0042] The bottom plate 133 is inserted into the gap 131c of the return structure 131d of another roof material 130 provided in the lower tier, or into the gap between the roof material 150 and a pressing piece 163 of a fastener 160 fastened to another roof material 150 provided in the lower tier, and engages with the return structure 131d or the pressing piece 163 of the fastener 160. Therefore, the return structure 135 consisting of the side plate 132 and the bottom plate 133 engages with the other roof material 130 or roof material 150 arranged on the eaves side.

[0043] The multiple roof materials 130 and panel roof materials 150 are arranged adjacent to each other in the vertical direction, with some of the roof materials 130, 150 overlapping each other.

[0044] The panel-mounted roofing material 150 comprises a top plate 151, side plates 152, a bottom plate 153, a solar panel 250 fixed to the front surface of the top plate 151, and a concave-convex panel 125 fixed to the back surface of the top plate 151.

[0045] The panel-attached roofing material 150 is formed by bending a steel plate having a thickness of, for example, about 0.35 mm to 0.40 mm, so that a top plate 151, side plates 152, and bottom plate 153 are integrally formed. For example, the panel-attached roofing material 150 configures a return structure 155 that covers the lower end side of the fastener 160 by the side plates 152 and bottom plate 153 that are bent at two points from the end of the top plate 151 on the eaves 12 side.

[0046] The top plate 151 is configured in a plate shape having a predetermined width and depth, and covers the front side of the sheathing board 110 and the underlayment material 120. The top plate 151 is set to a length that covers a part of the top plates 131, 151 of another panel-attached roof material 150 or roof material 130 arranged in the first direction.

[0047] A solar panel 156 is provided on the surface of the top plate 151. The solar panel 156 includes a substrate and an electrode formed on the substrate. The electrode of the solar panel 156 is connected to a terminal box 158 disposed on the back side of the top plate 151. A cable 157 for outputting electric power is connected to the terminal box 158.

[0048] The terminal box 158 is configured to be able to connect a plurality of cables 157, each of which is connected to a plurality of solar panels 156 provided on the surface of each panel-mounted roofing material 150. As an example, the terminal box 158 is installed on the back surface of each panel-mounted roofing material 150. For example, the cable 157 connected to the panel-mounted roofing material 150 is connected to the cable 157 of the adjacent panel-mounted roofing material 150 and wired in series. Then, multiple serially connected wires are routed together indoors. Note that the multiple cables 157 may be routed indoors, for example, from the back side of the roofing material 150 through the eaves 12, or through the opening 111 of the sheathing board 110.

[0049] Here, the depth refers to the direction of the underwater (eaves 12) side and the abovewater (ridge 11) side of the roof structure 1. A step 151b is formed along the width direction at a midpoint in the vertical direction of the top board 151. The step 151b has an inclined surface extending along the second direction. The step 151b does not necessarily have to be formed.

[0050] The top plate 151 also includes a return structure 151d at the edge on the ridge side, which has a return piece 151c that is bent toward the front side and extends toward the eaves side. The return structure 151d regulates the position of the end of the base piece 161 of the fixture 160, for example, depending on the position of the fixture 160.

[0051] The side plate 152 connects the top plate 151 and the bottom plate 153 together. The side plate 152 covers the eaves 12 side of the pressing piece 163 of the fixing device 160. The width dimension of the side plate 152 is set to, for example, the same dimension as the width dimension of the top plate 151. The side plate 152 is disposed on the eaves 12 side of the top plate 151. The side plate 152 is inclined at an acute angle, for example, 45°, with respect to a surface along the surface direction of the top plate 151 and a direction perpendicular to the top plate 151 so that the bottom plate 153 side is closer to the eaves 12 side than the top plate 151 side.

[0052] In other words, the side panel 152 is inclined at an obtuse angle, for example 135°, with respect to the underside of the top panel 151 (the main inner surface of the panel-mounted roof material 150). Note that the surface along the surface direction of the top panel 151 here refers to an imaginary plane extending along the surface direction of the top panel 151 from the end of the top panel 151 on the side panel 152 side.

[0053] The bottom plate 153 is set parallel or nearly parallel to the top plate 151. Therefore, the inclination angle of the side plate 152 with respect to the bottom plate 153 is set to an acute angle, for example, 45°. The interval between the top plate 151 and the bottom plate 153 is configured to allow the pressing piece 163 of the fixing device 160 to be arranged. The width dimension of the bottom plate 153 is set to the same dimension as the width dimension of the top plate 151. The depth dimension of the bottom plate 153 is set to be shorter than the depth dimension of the top plate 151. More specifically, the depth dimension of the bottom plate 153 is set to a dimension that is closer to the eaves side than the ridge side end of the top plates 131, 151 of another roof material 130 adjacent below or another panel-attached roof material 150. The bottom plate 153 has a double structure having a folded piece 153a where the plate material is folded back to the back side at a folding position separated by a predetermined distance from the side plate 152.

[0054] The bottom plate 153 is inserted into the gap 131c of the return structure 131d of the other roof material 130 provided in the lower tier, or into the gap between the roof material 150 and a pressing piece 163 of a fastener 160 fastened to the other roof material 150 provided in the lower tier, and engages with the return structure 131d or the pressing piece 163 of the fastener 160. In other words, the return structure 155 consisting of the side plate 152 and the bottom plate 153 engages with the other roof material 130 or roof material 150 arranged on the eaves side.

[0055] The return structure 155 may have a hole 154 for draining water.

[0056] A plurality of panel roof materials 150 are arranged adjacent to each other in the vertical direction, partially overlapping with adjacent other roof materials 150 and roof materials 130.

[0057] Each roof material 130 and each panel-attached roof material 150 has its top plate 131, 151 fastened to the sheathing board 110 together with the fasteners 160, the underlayment material 120, and the uneven panel 125 by fastening members 165.

[0058] An uneven panel 125 having a plurality of protrusions is provided on the back side of the top plate 151 of the roof material 150. For example, the uneven panel 125 may be attached in advance to the back side of the top plate 151 of each roof material 150 by gluing or fastening, or may be configured as a separate member that is overlapped and assembled at the same time when the roof material 150 is assembled.

[0059] The uneven panel 125 is a panel member formed from, for example, a resin material. The uneven panel 125 is disposed between the sheathing board 110 and the roof materials 130 and 150. In this embodiment, the uneven panel 125 is disposed between the underlayment material 120 on the sheathing board 110 and the roof materials 130 and 150. For example, the uneven panel 125 is adhered to the back surface of each of the roof materials 130 and 150 in advance.

[0060] For example, the uneven panel 125 integrally includes a base plate portion 125a and a plurality of protrusions 125b protruding from the base plate portion 125a toward the back side, that is, toward the roof board 110, and having an uneven shape.

[0061] The base plate portion 125a is formed in a flat plate shape. The base plate portion 125a is disposed on the rear side of the roof material 150 and joined to the rear surface of the roof material 150. The base plate portion 125a formed between the multiple protrusions 125b on the rear surface side of the uneven panel 125 forms a rear recess 125c recessed from the sheathing board 110 side to the roof materials 130, 150 side.

[0062] In addition, the base plate portion 125a has, as a part thereof, a flat installation portion 125e without the protrusion 125b. For example, the installation portion 125e has an area larger than that of the terminal box 158. The installation portion 125e forms a box accommodating space between the sheathing board 110 or the underlayment material 120 and the sheathing board 110 or the underlayment material 120, in which the terminal box 158 for wiring can be placed.

[0063] The multiple protrusions 125b are arranged in a matrix with a space between them in the first and second directions. That is, the multiple protrusions 125b are arranged in a matrix with a plurality of rows along the first and second directions. The protrusions 125b are configured in a frustum-like cup shape with an apex on the back side. The protrusions 125b are cup-shaped with a recess on the back side when viewed from the front side, and form a truncated cone-shaped surface when viewed from the back side. The peripheral surface of the protrusions 125 is configured in a tapered shape, and the width of the back recess 125c is formed in a tapered shape that widens toward the sheathing board 110 side in the groove depth direction. For example, the front side of the cup-shaped protrusions 125b is configured in a hollow shape.

[0064] The multiple convex portions 125b are arranged in the first direction and the second direction at a predetermined interval L determined according to the allowable radius of curvature of the cable 157. For example, the interval L is set to be equal to or greater than the allowable radius of curvature D, which is the minimum value of the bending radius determined for each cable 157. For example, the allowable radius of curvature D is determined to be equal to or greater than twice the outer diameter of the cable 157. As an example, in this embodiment, when the outer diameter of the cable 157 is φ6 mm and the allowable radius of curvature D is 52 mm, the interval L of the convex portions 125b is set to 68 mm; when the allowable radius of curvature D is 56 mm, the interval L of the convex portions 125b is set to 72 mm; when the allowable radius of curvature D is 60 mm, the interval L of the convex portions 125b is set to 76 mm; and when the allowable radius of curvature D is 66 mm, the interval L of the convex portions 125b is set to 82 mm.

[0065] The interval L between the protrusions 125b is set to a predetermined value that prevents a worker from stepping through the protrusions 125b in the first direction, the second direction, and the diagonal direction, which are the arrangement directions, and is set to a predetermined value that is equal to or smaller than the predetermined dimension that prevents a worker from stepping through the protrusions 125b. In other words, the interval L is set to a value small enough to prevent the base plate 125a from being deformed by the protrusions 125b during work.

[0066] The uneven panel 125 has a plurality of rear recesses 125c extending in the first and second directions on the rear surface of the base plate portion 125a. The rear recesses 125c are gaps formed between the plurality of protrusions, and are configured to allow the cable 157 to be disposed therein.

[0067] For example, the uneven panel 125 is cut into a shape corresponding to the surrounding members of the portion where it is to be disposed, and then assembled. For example, by forming an opening by cutting out the portion where the terminal box 158 is to be disposed, it is possible to secure a storage space for arranging the components. The height of the protrusions 125b may be uniform, or a configuration may be provided in which multiple types of protrusions 125b with different heights are provided.

[0068] The fixing device 160 is positioned between the ridge side return structure 151d of the top plate 151 of the eaves side panel roofing material 150 and the eaves side return structure 155 of the ridge side panel roofing material 150 of the two panel roofing materials 150 lined up in the inclined direction.

[0069] Fixture 160 is formed by bending a metal plate, and has a base piece 161 and a pressing piece 163 as a pressing portion, which are integrally and continuously formed. Fixture 160 may have a step for reinforcement or drainage.

[0070] As an example, the fastener 160 has a width dimension equal to the width dimension of the roof material 150. Alternatively, the fastener 160 may be configured to be longer than the width dimension of the roof material 150. For example, multiple fasteners 160 are arranged adjacent to each other in the width direction of the roof structure 1 and provided over the entire length of the roof structure 1 in the width direction. Alternatively, the fastener 160 may be configured to be larger or smaller than the width dimension of the roof material 130, and may be configured to be provided on a portion of the width direction of the roof structure 1.

[0071] The base piece 161 is configured, for example, as a rectangular plate having a predetermined width in the first direction and extending along the second direction. The base piece 161 may have fastening holes as fastening parts through which fastening members pass. The base piece 161 has an engagement piece 161a on the ridge side as a locking part that is bent, for example, toward the roof material 130, and the engagement piece 161a is engaged and held within a return structure part 151d at the edge of the top plate 151 of the panel-attached roof material 150, and is positioned.

[0072] The base piece 161 is configured, for example, in the shape of a rectangular plate having a predetermined width and depth. The base piece 161 of the fixture 160 is fixed to the panel-attached roof material 150 by fastening members such as screws.

[0073] The pressing piece 163 is formed continuously on the eaves side of the base piece 161. The pressing piece 163 is integrally provided with a valley-shaped roof pressing piece 163a, which is formed by bending one side of the base piece 161 along the top plate 151, bending it to the eaves side and the back side, and folding it back to stand on the front side, and a back pressing piece 163b, which is bent further to the back side from the end of the eaves side of the roof pressing piece 163a and folded back. The top of the back pressing piece 163b becomes an engagement part that is engaged with the corner part between the side plate 152 and the bottom plate 153 of the panel-attached roof material 150. For example, a part of the roof pressing piece 163a is bent and extends along the inclined surface of the step 151b. In addition, the part on the edge side of the back pressing piece 163b extends along the side plate 152.

[0074] The fastener 160 is disposed between a pair of roof materials 130, 150 adjacent in the tilt direction, on the front side of the edge of the top plate 151 of the roof material 150 disposed on the eaves side and back side, and inside the return structure 135, 155 of another roof material 1130, 150 disposed on the ridge side and front side. The fastener 160 is fastened to the top plate 131, 151 of the roof material 130 or the roof material 150 and the sheathing board 110. That is, the base piece 161 of the fastener 160 is fastened to the top plate and uneven panel 125 of the roof material 150 and the sheathing board 110 by the fastening member 165, and the pressing piece 163 engages with the return structure 135, 155.

[0075] The fastening members 165 are, for example, screws with gaskets. The fastening members 165 are used, for example, to fasten the roofing materials 130, 150 to other roofing materials 130, 150. For example, the roofing materials 150 are fastened to the sheathing boards individually via the fasteners 160, and the roofing materials 130 are fastened to the sheathing boards individually at their rear end portions.

[0076] The fastening member 165 has, for example, a disk-shaped head 165a and a cylindrical nail portion 165b integrally therewith, and an annular packing is provided on the outer periphery of the base end portion on the head side of the nail portion 165b. The nail portion 165b has a protrusion formed in a spiral shape on its outer circumferential surface.

[0077] Adjacent panel roofing materials 150 or adjacent base roofing materials 130 in the width direction are bonded together with, for example, waterproof tape.

[0078] The eaves end water trim 170 is provided, for example, along the width direction (second direction) of the eaves end 12. The eaves end water trim 170 has, for example, a base portion disposed between the sheathing board 110 and the underlayment material 120 at the eaves end 12, and a water trim board hanging down from the end portion of the base on the eaves end 12 side. The water trim board has a return portion on the sheathing board 110 side of the lower end.

[0079] The gable trimmer 180 is disposed, for example, in each gable 13. The gable trimmer 180 is fastened to the sheathing board 110 via a coping, for example. The gable trimmer 180 has a trim plate that hangs downward from the gable 13.

[0080] Next, a method for attaching the panel-attached roofing material 150 in the manufacturing method for the roof structure 1 according to this embodiment will be described. The method for attaching the panel-attached roofing material 150 according to this embodiment includes a fixing step of fastening the fasteners 160 to the roofing materials 130, 150, and an assembly step of covering the roofing material 150 on the fasteners 160 and assembling them.

[0081] 17 to 21 are explanatory diagrams showing an example of the assembly process of the roofing material 150. For example, as shown in FIG. 17 to FIG. 21, in the assembly process, the roofing materials 130 or the panel-attached roofing materials 150 are sequentially installed in a fixed width or in one row extending in the width direction, in order from the row on the eaves side to the row on the ridge side. As an example of installation, a plurality of roofing materials 130 and a plurality of roofing materials 150 are sequentially installed. Alternatively, some of the roofing materials 130 laid in advance are removed and the panel-attached roofing materials 150 are installed instead. Alternatively, the surface of some of the plurality of roofing materials 130 laid in advance may be covered with the panel-attached roofing material 150. As an example, in this embodiment, a case will be described in which the roofing materials are laid in order from the lower row to the upper row, and the roofing materials 130, 150 are arranged in multiple rows on the upper side of the roofing materials 130, 150 laid in the lower row.

[0082] Of the pair of roofing materials 130, 150 which are partially stacked and aligned vertically, the roofing material 130, 150 on the ridge 11 side will be described as the first roofing material 130, 150, and the roofing material 130, 150 on the eaves 12 side will be described as the second roofing material 130, 150.

[0083] For example, multiple roof materials 130, 150 are assembled by laying them up in order starting from the eaves 12 side. For example, when the base roof material 130, the multiple layers of panel-attached roof materials 150, and the base roof material 130 are arranged in order from the eaves 12 side, they are assembled along the inclination direction in the order of the connection structure A3, the connection structure A2, and the connection structure A1, as shown in Figure 5 as an example. Note that when the base roof materials 130 are arranged in multiple layers on the ridge 11 side or the eaves 12 side as shown in Figure 1, a connection structure A4 is provided.

[0084] In the connecting structure A4, for example, when connecting another roof material 130 to the ridge side of the roof material 130, the return structure 135 of the roof material 130 on the ridge side is inserted into and engaged with the return structure 131d of the roof material 130 on the eaves side.

[0085] In the connection structure A3, the process of placing the panel-attached roof material 150 on the ridge 11 side of the roof material 130 on the eaves 12 side is as follows: first, the bottom plate 153 of the roof material 150 is inserted into the return structure 131d provided on the roof material 130 on the eaves 12 side, and the return structure 131d is engaged with the return structure 155, thereby assembling the roof material 150 by overlapping it on a portion of the roof material 130.

[0086] When connecting another roof material 150 to the ridge side of the roof material 150 as the connecting structure A2, the fixing device 160 is set on the top plate 151, and the return structure part 155 of the other roof material 150 on the ridge side is inserted into and engaged with the pressing piece 163 of the fixing device 160. That is, as a process of placing the roof material 150 on the ridge 11 side of the roof material 150 on the eaves 12 side, the fixing device 160 is first placed on the top plate 151 of the roof material 150 on the eaves 12 side. As an example, the fixing device 160 is temporarily fixed by attaching it to the top plate 151 with a waterproof tape 169 or the like. At this time, the engaging piece 161a of the base piece 161 is inserted into and engaged with the return structure part 151d of the top plate 151 of the roof material 150, thereby positioning and holding the panel-attached roof material 150 on the eaves side (fixing device installation process).

[0087] Then, the base piece 161 of the fixture 160, the roof material 150, and the sheathing board 110 are fastened together by fastening members 165 so as to penetrate therethrough (fastening step).

[0088] 16, the fastener 160 may be attached to the return structure 151d of the top plate 151 of the panel-attached roof material 150 (second roof material) at a position where the engagement piece 161a of the base piece 161 is inserted, or at a position away from the return structure 151d. For example, the attachment position of the fastener 160 can be adjusted appropriately depending on the relative positions of the roof material 130 and the panel-attached roof material 150. For example, the engagement piece 161a of the base piece 161 may be positioned and fastened from above a position shifted to one side or the other side in the tilt direction from the return structure 151d.

[0089] After the fasteners 160 are fastened, the panel-attached roofing material 150 is attached to the fasteners 160 (attaching process). At this time, the bottom plate 153 of the panel-attached roofing material 150 on the ridge 11 side is inserted into the gap formed between the fastener 160 and the top plate 151 of the panel-attached roofing material 150 on the eaves 12 side while attaching it. As a result, the panel-attached roofing materials 150 lined up vertically are arranged with parts overlapping each other.

[0090] Furthermore, when assembling roof material 130 to the ridge side of roof material 150 as connection structure part A1, the same steps as described above are performed: a fastener installation step of installing fastener 160 on roof material 150, a fastening step of fastening fastener 160, and an installation step of attaching roof material 130 to fastener 160.

[0091] The above fastening process and installation process are repeated the required number of times in order from the row on the eaves 12 side to the row on the ridge 11 side, thereby completing the installation of multiple layers of roof materials 130, 150.

[0092] As shown in Figures 11 and 12, a joint tape 260 is provided at the boundary between multiple roofing materials 130, 150 adjacent in the second direction. The joint tape 260 has a first adhesive piece 261 adhered to the surface of one roofing material, a second adhesive piece 262 adhered to the surface of the other roofing material, and a bag-shaped connecting piece 263, which are integrally and continuously arranged. The connecting piece 263 extends from the edge of the first adhesive piece 261, is folded back on the back surface side of at least one of the roofing materials 130, 150, and reaches the edge of the second adhesive piece 262.

[0093] In the roof structure 1, an uneven panel 125 is arranged on the back side of the panel-mounted roofing material 150 having the solar panel 156, and the convex portion 125b of the uneven panel 125 reinforces the panel-mounted roofing material 150, suppresses deformation of the panel-mounted roofing material 150, and ensures space.

[0094] According to the panel-equipped roofing material 150 and roof structure 1 configured in this manner, the uneven panel 125 having uneven portions is disposed on the back side of the roofing material 150, which makes it easier to route the cable 157 of the solar panel 156. That is, by routing the cable 157 through the back recess 125c formed between the protrusions 125b, the cable 157 can be positioned by the protrusions 125b, improving workability. In addition, the convex portion 125b is made of resin and has a truncated cone cup shape, which allows for weight reduction, strength, and heat insulation, and can protect the terminal box 158 and the cable 157 provided on the back side of the roof material 150. In addition, the convex portions 125b are arranged in a matrix, which makes it easy to set the route for the cable 157 and provides a high degree of freedom. In addition, the uneven panel 125 has the back recesses 125c formed between the convex portions 125b arranged in a matrix extending in a straight line to form a passage, thereby providing higher breathability than, for example, a configuration in which heat insulating material is arranged over the entire surface. Therefore, the temperature rise of the solar panel can be suppressed and a decrease in power generation efficiency can be prevented. Furthermore, since the peripheral surface of the convex portion 125b is a tapered truncated cone shape, it is easy to arrange the cable 157 in the tapered back recesses 125c. In addition, the convex portions 125b are tapered cup shapes, which makes it easy to align multiple panel members 125 of the same shape when they are stacked and arranged, and also allows for dimensional precision to be relaxed.

[0095] Also, by setting the arrangement of the convex parts 125b in the uneven panel 125 to be equal to or greater than the allowable radius of curvature of the cable 157, damage to the cable can be prevented. Also, by setting the interval between the convex parts 125b to be equal to or greater than the allowable radius of curvature, the bending conditions of the cable 157 can be satisfied regardless of where the cable 157 is passed through, improving workability during construction. For example, when the position of the cable 157 needs to be changed for some reason during construction, this can be flexibly dealt with. Therefore, wiring is easier than when the wiring route is determined in advance, such as when using insulation made of sprayed rigid urethane foam, or when the wiring route is greatly restricted.

[0096] Furthermore, since the uneven panel 125 is made of plastic resin and is easy to process and manufacture, it is easy to set the size and arrangement of the concave and convex parts, and the design can be easily changed according to conditions such as the size of the cables and connectors of the target solar panel, resulting in high productivity.

[0097] In addition, since the fixing device 160 in the above embodiment allows for position adjustment, for example, during renovation, even if the length of the existing roofing material and the roofing feet, i.e., the length in the tilt direction, differs slightly, a covering construction method is possible in which a panel-attached roofing material 150 of different dimensions is assembled on the existing roofing material 130 by adjusting the position of the fixing device 160. Note that if the lengths of the roofing feet differ, waterproofing can be ensured by placing a waterproof sheet at the joint.

[0098] The present invention is not limited to the above-described embodiment, and various modifications can be made in the implementation stage without departing from the spirit of the invention.

[0099] For example, in the above embodiment, the arrangement and number of the base roof material 130 and the panel roof material 150 are not limited to those described above. Furthermore, the configuration of the fastener 160 is not limited to the above example.

[0100] In the above embodiment, an example in which a panel-attached roofing material 150 of a different shape is added and assembled to an existing roofing material 130 has been shown, but the present invention is not limited to this. For example, as in the roof structure 1A shown in FIG. 22 as another embodiment, the panel-attached roofing material 150 may be installed so that the position in the inclination direction is aligned with the existing roofing material 130. In this case, the center of the roof structure 1A is installed with the panel-attached roofing material 150, and the area near the ridge 11, the gable 18, and the eaves 12, which are the peripheral parts of the roof structure 1A, is installed with another metal horizontal roofing material 130. Even if the dimensions of the roofing material 130 are slightly different, they can be aligned with the other roofing materials 130 by adjusting the position of the fasteners 160, so that the appearance and workability are good. In addition, by combining with another roofing material 130, it is possible to reduce costs and achieve a configuration with high workability, weather resistance, and design.

[0101] As another embodiment, for example, as in roof structure 1B shown in Fig. 23, the entire roof may be constructed only with panel-attached roofing materials 150 of the same shape. Also, during renovations and the like, it is possible to overlay and install panel-attached roofing material 150 on the surface of existing roofing material 130. Even in these cases, the uneven panel 125 is disposed on the back surface, improving the ease of handling of wiring.

[0102] In the above embodiment, a horizontally-roofed roof structure is exemplified, but the present invention is not limited to this. For example, as shown in Figs. 24 and 25, a so-called vertically-roofed roof structure may be used as another embodiment. Figs. 24 and 25 are perspective views showing a roof structure 1C according to another embodiment. The roof structure 1C includes a plurality of roof materials 150A. Each roof material 150A extends in an inclined direction and has an engagement structure at its edge in the width direction. For example, a rail protrusion 152A is formed at one end in the width direction, and a cover protrusion 153A that covers the outer surface of the rail protrusion 152A and engages with the rail protrusion 152A is formed at the other end in the width direction. The rail protrusion 152A has a wedge-shaped cross-sectional shape and is formed uniformly in the inclined direction. The cover protrusion 153A has a rail groove in which the rail protrusion 152A is arranged, and is formed uniformly in the inclined direction. The plurality of roof materials 150A are arranged continuously in the width direction. Adjacent roof materials 150A overlap each other partially, and are connected in the width direction by engaging the rail protrusion 152A with the cover protrusion 153A. Specifically, the cover protrusion 153A on the other end side of the roof material 150A arranged on one side engages with the rail protrusion 152A of the roof material 150A arranged on the other end side. Also, the rail protrusion 152A on one end side of the roof material 150A engages with the cover protrusion 153A of the other roof material 150A adjacent to one side.

[0103] The front surface side of each roof material 150A is provided with a plurality of solar panels 156. Also, the rear surface of each roof material 150A is provided with an uneven panel 125. The rest of the configuration is the same as in the above embodiment.

[0104] In this embodiment as well, by disposing uneven panel 125 having uneven portions on the back side of roofing material 150A, cable 157 of solar panel 156A can be easily routed. That is, by disposing cable 157 through back recess 125c formed between protrusions 125b, cable 157 can be positioned by protrusions 125b, improving workability.

[0105] In the above embodiment, an example in which the multiple roof materials 130, 150 are connected using the fastener 160 as the roof structure is shown, but the present invention is not limited to this. FIG. 26 is an explanatory diagram showing a roof structure 1D according to another embodiment. The roof structure 1D includes multiple roof materials 130. For example, as shown in FIG. 26, the multiple roof materials 130 are connected by an engagement portion provided on the roof materials 130, not by the fastener 160. That is, the multiple roof materials 130 are engaged by inserting the bottom plate 133 of the adjacent roof material 130 into the gap 131c of 131d provided at the edge of the top plate 131 of one roof material. The multiple roof materials 130 include an uneven panel 125 attached to the back side of the top plate 131. The other configurations are the same as those of the first embodiment and the like. In this embodiment, the uneven panel 125 is arranged to achieve the same effects as those of the above embodiments.

[0106] For example, the uneven panel 125 has the same shape as the back surface of each roofing material 150, and is attached to the back surface of each roofing material 150, but this is not limited to the above. For example, the uneven panel 125, which is made of a separate material from the roofing material 150, may be configured to be overlapped and assembled at the same time as the roofing material 150 is assembled, or may be set on the underlayment material 120 in advance.

[0107] In addition, the uneven panel 125 has the same shape as each roofing material 150 and is provided for each roofing material 150, but the present invention is not limited to this. For example, the uneven panel 125 may be smaller than the roofing material 150 or larger than the roofing material 150, and may be a size corresponding to a plurality of roofing materials 150. In the above embodiment, the uneven panel 125 is provided on the panel-attached roofing material 150 having a solar panel, but the present invention is not limited to this. The uneven panel 125 may be provided on the back of other types of roofing materials, or may be set in advance on the underlayment material 120 in an area spanning a plurality of types of roofing materials 130, 150. The uneven panel 125 may be divided into a plurality of parts at a position different from the boundary portion between the roofing materials 130, 150.

[0108] A configuration may be adopted in which a plurality of the uneven members are stacked in at least a portion of the space formed between the roofing material and the sheathing board. That is, the uneven panel 125 may be stacked twice in a portion. The tapered shape allows easy stacking, so the overlapping position can be adjusted as needed.

[0109] The shape of each of the protrusions 125b is not limited to the above, and may be a dome shape in cross section in another embodiment.

[0110] In another embodiment, the heights of the multiple protrusions 125b may be different. For example, the heights may be set according to the size of the gap to be formed, and the height of the protrusions may be increased in a portion where the gap in the thickness direction between the roof materials 130 and 150 below is large.

[0111] Furthermore, the arrangement conditions of the convex parts 125b of the uneven panel 125 are not limited to the above. For example, by ensuring an interval that satisfies the conditions required for the support structure, such as the condition that a worker does not step through the cable during work, the cable may be adapted to various diameters of the cable 157.

[0112] In the above embodiment, the roof structure is formed by combining a plurality of types of roof materials 130, 150, but the present invention is not limited to this. For example, the roof structure may be formed by using a plurality of roof materials 150 of the same type.

[0113] In addition, each embodiment may be implemented in appropriate combination, in which case the combined effect can be obtained. Furthermore, the above-mentioned embodiment includes various inventions, and various inventions can be extracted by combinations selected from the multiple constituent elements disclosed. For example, if the problem can be solved and the effect can be obtained even if some constituent elements are deleted from all the constituent elements shown in the embodiment, the configuration from which the constituent elements are deleted can be extracted as an invention.
