The outdoor side end portion of the eaves portion 10 is composed of a nose cover 11 (nasal plate) that is inclined so as to be located on the indoor side downward.

  The roof base of the building 1 is composed of a field plate 12 provided on a structural frame such as a rafter. The field board 12 is inclined downward at a uniform angle from the ridge side toward the eave side, and is parallel to the roof gradient. The eaves side end of the base plate 12 protrudes to the outdoor side from the nose cover 11.

  A drainer 5 which is long in the eave direction is provided at the eaves side end of the base plate 12. The drainer 5 is made of a steel plate. The drainer 5 may be formed of a metal plate other than a steel plate, and the material thereof is not limited to metal.

  The drainer 5 has a plate-like placement part 50 and a piece-like hanging part 51 that hangs down from the outdoor side edge of the placement part 50. The placement portion 50 that protrudes from the upper edge portion of the hanging portion 51 toward the ridge side is placed on the base plate 12. The hanging portion 51 is disposed on the outdoor side of the field board 12 and protrudes downward from the eaves side end of the field board 12. The drooping portion 51 covers the eaves side end face of the field board 12, and rainwater adhering to the outdoor side surface flows down from the lower edge of the drooping portion 51.

  A front door 2 that is long in the eave direction is provided side by side in the eave direction at the end of the eaves side of the field board 12. The face door 2 is made of a steel plate. In addition, you may form the face door 2 with metal plates other than a steel plate. Moreover, the material of the face door 2 is not limited to a metal.

  As shown in FIG. 4, the face door 2 has a plate-like portion 20, a plurality of cover portions 22, and a pressing portion 23 provided in each cover portion 22. The plate-like portion 20 is formed in a substantially rectangular shape that is long in the eave direction. A plurality of openings 201 are formed side by side at a predetermined interval in the longitudinal direction of the plate-like portion 20 on the outdoor side portion of the plate-like portion 20. Each opening 201 penetrates in the thickness direction of the plate-like portion 20 and is formed in a rectangular shape that is long in the eave direction. Each opening 201 is formed at a position in front of the edge of the plate-like portion 20 on the ridge side, and the end on the outdoor side of the plate-like portion 20 is a protruding portion 203 that protrudes to the outdoor side from the opening 201. Yes.

  The outdoor side portion of the protruding portion 203 is a draining portion 204. The draining portion 204 extends in the eave direction of the plate-like portion 20. The draining portion 204 projecting from the projecting base portion of the projecting portion 203 toward the outdoor side is inclined with respect to the ridge side portion of the plate-like portion 20 with respect to the draining portion 204, and as shown in FIG. When construction No. 2 is done, it slopes down toward the outdoor side with a steeper slope than the roof slope. In addition, the plate-like portion 20 is a fixed portion 200 that is fixed to the base plate 12 at a portion protruding to the ridge side from each opening 201.

Rising piece portion 202 is raised to the indoors side edge of each opening 201 of the plate-like portion 20 as shown in FIG. Each upright piece 202 is shorter than the cover portion 22, and when the face door 2 is constructed as shown in FIG. 3, there is a gap 15 between the top surface portion of the convex portion 30 of the uneven roof material 3. It is supposed to be formed.

  As shown in FIG. 4, the cover 22 is erected on the outdoor side edge of each opening 201. Each cover portion 22 is formed in a plate shape that intersects the plate-like portion 20 at a right angle. Each cover part 22 is formed in a substantially rectangular shape. Specifically, each cover portion 22 is formed in an isosceles trapezoidal shape having a lower bottom larger than an upper bottom. The holding part 23 is composed of a piece protruding from the upper edge of the cover 22 toward the ridge. The holding part 23 is substantially parallel to a part of the plate-like part 20 excluding the draining part 204. Each cover part 22, each pressing part 23, each opening 201, and each upright piece part 202 are formed by, for example, partially cutting up a long plate material constituting the plate-like part 20.

  As shown in FIG. 3, the fixed portion 200 of the face door 2 is placed on the field plate 12 via the placement portion 50 of the drainer 5. Here, in the plurality of face doors 2, the plate-like portions 20 are arranged side by side in the eave direction, and the plate-like portions 20 of the adjacent face doors 2 are adjacent to each other with their end faces being abutted. The fixed portion 200 of each face door 2 is fixed to the eaves side end portion of the field board 12 together with the mounting portion 50 of the drainer 5 by fixing with a fixing tool such as a screw or a nail. In addition, you may fix the mounting part 50 of the drainer 5, and the fixing | fixed part 200 of the face door 2 to the field board 12 by adhesion | attachment with an adhesive agent. The outdoor portion of the plate-like portion 20 of each face door 2 protrudes from the field plate 12 to the outdoor side. Each opening 201 of each face door 2 is arranged on the outdoor side with respect to the base plate 12 in the eaves-ridge direction.

  As shown in FIG. 2, a plurality of uneven roof materials 3 are placed side by side in the eave direction on the field board 12. As shown in FIG. 3, the eaves side portion of each uneven roof material 3 is placed on the base plate 12 via the fixed portion 200 of the face door 2 and the placement portion 50 of the drainer 5. That is, the fixed portion 200 of the face door 2 and the mounting portion 50 of the drainer 5 are sandwiched and fixed between the base plate 12 and the bottom surface portion of the concave portion 31 of the uneven roof material 3.

  Each uneven roof material 3 is made of a steel plate. In addition, each uneven | corrugated roof material 3 may be formed with metal plates other than a steel plate, and the material is not limited to a metal. As shown in FIG. 4, each uneven roof material 3 has a convex portion 30 that opens downward and protrudes upward, and a concave portion 31 that opens upward and dents downward. The convex portions 30 and the concave portions 31 are alternately formed in the eave direction. The side surface portion of each convex portion 30 also serves as the side surface portion of the adjacent concave portion 31. The side surface portion is substantially orthogonal to the top surface portion of the convex portion 30 and the bottom surface portion of the concave portion 31. Specifically, both side surface portions of the convex portion 30 are slightly inclined so as to be positioned outward in the width direction of the convex portion 30. The width of each convex portion 30 and the width of each concave portion 31 are uniform in the eaves-ridge direction.

  Although not shown in the drawings, the adjacent uneven roof materials 3 are connected via a connector provided on the base plate 12. The coupling tool is fixed to the base plate 12 by fixing with a fixing tool such as a screw or a nail. Thereby, each uneven | corrugated roof material 3 is fixed to the field board 12 via a connection tool. In addition, a cover member is attached to the connector, and the portion between the adjacent uneven roof materials 3 and the connector disposed here are covered by the cover member.

  As shown in FIG. 3, a ventilation space 13 is formed between the base plate 12 and each uneven roof material 3 disposed thereon. The ventilation space 13 is a space surrounded by the convex portions 30 and the base plate 12, and is formed in the same number as the convex portions 30 of the uneven roof material 3 in the eaves direction. Each ventilation space 13 is formed over substantially the entire length in the eaves-ridge direction of the uneven roof material 3.

  The eaves side edge part of each uneven roof material 3 protrudes to the outdoor side rather than the eaves side edge of the field board 12 in the eaves ridge direction. Each opening 201 of the face door 2 is located below the corresponding eaves side end of the convex portion 30. Each opening 201 of the face door 2 communicates with the ventilation space 13 formed in the corresponding convex portion 30. Thereby, outside air is introduced into the ventilation space 13 through the opening 201 of the corresponding face door 2. That is, each opening 201 of the face door 2 functions as a vent for introducing outside air into the vent space 13. Although illustration is omitted, the ridge side end portion of each convex portion 30 is opened, so that the outside air introduced into each ventilation space 13 is discharged from the ridge side. Moreover, the opening 201 is not formed in the part corresponding to each recessed part 31 of the uneven roof material 3 in the plate-shaped part 20 of the face door 2, The same part supports the bottom face part of the corresponding recessed part 31 from the bottom. .

  The eaves side edge part of each convex part 30 of the uneven roof material 3 is inserted under the pressing part 23 of the corresponding face door 2 as shown in FIG. Further, the rising piece 202 of the corresponding face door 2 is fitted inside each convex portion 30. In order to insert the eaves side end part of each convex part 30 of the uneven roof material 3 below the pressing part 23, for example, the following process is performed. First, the concavo-convex roof material 3 is arranged on the field board 12 so that the convex part 30 is located on the ridge side of the cover part 23 of the face door 2 that is first placed and fixed on the field board 12. At this time, the rising piece 202 of the face door 2 corresponding to the inside of each convex portion 30 of the uneven roof material 3 is fitted. And this uneven roof material 3 moves to the eaves side along the field board 12 along the both sides | surfaces of the convex part 30 corresponding to the both sides of each standing piece part 202. As shown in FIG.

  Each pressing portion 23 of the face door 2 is placed on the eaves side end portion of the upper surface of the corresponding convex portion 30 as shown in FIG. For this reason, when the uneven roof material 3 tries to float from the base plate 12 due to wind or the like, the eaves side end of the top surface portion of the convex portion 30 of the uneven roof material 3 is pressed by the pressing portion 23. It has become.

  Each cover part 22 of the face door 2 is in contact with the eaves side end face of the corresponding convex part 30. Each cover part 22 faces the eaves side opening of the corresponding convex part 30, and covers the opening. For this reason, rainwater, small birds, insects, and the like are difficult to enter the convex portion 30.

  The width b1 (see FIG. 4) of each cover 23 of the face door 2 is larger than the width b2 (see FIG. 4) of the corresponding protrusion 30 over the entire length of the cover 23 in the vertical direction. Thereby, the both-sides edge part of the width direction of each cover part 22 becomes the dam part 220 which protruded toward the recessed part 31 side rather than the side part of the corresponding convex part 30, as FIG. 1 shows. The blocking portion 220 protrudes from the side surface portion of the convex portion 30 across the top and bottom of the cover portion 22. In this way, at the eaves side end of each recess 31, the damming portion 220 of the face door 2 protrudes from the side surface portion of the convex portion 30 on both sides toward the outer side in the width direction of the convex portion 30. For this reason, when rainwater flows in the concave portion 31 of the uneven roof material 3 toward the eaves side, the rainwater flowing toward the eaves side along the side surface portion of the concave portion 31 is weired on both sides of the eaves side end portion of the concave portion 31. It is designed to be dammed by the stop 220. And this rainwater flows toward the width direction center side of the recessed part 31 along the surface on the ridge side of the blocking part 220, and after that, from the eaves side opening of the recessed part 31, opening of the plate-shaped part 20 of the face door 2 is carried out. It flows out on the protrusion part 203 protruded to the outdoor side rather than 201. FIG. In addition, rainwater that has flowed from the top surface portion of the convex portion 30 to the outdoor side surface of the cover portion 22 through the upper surface of the pressing portion 23 also flows onto the protruding portion 203. Moreover, the rainwater which reached the protrusion part 203 of the plate-shaped part 20 of the face door 2 flows into the draining part 204 as mentioned above. The rainwater flows down the surface of the drainage portion 204 on the outdoor side, and flows down from the lower edge of the drainage portion 204.

  As shown in FIG. 3, the eaves 4 is provided along the eaves 10 on the outdoor side of the eaves 10. The eaves basket 4 is attached to the nose cover 11 via a fixture (not shown). The lower edge of the draining portion 204 and the lower edge of the hanging piece portion 51 of the draining portion 5 are located between the wall portions on both sides of the eaves 4 in the indoor / outdoor direction perpendicular to the outer wall of the building 1. For this reason, rainwater that has flowed down from the lower edge of the draining portion 204 of each uneven roof material 3 and the lower edge of the hanging piece portion 51 of the draining device 5 is received by the eaves fence 4. Each opening 201 of the face door 2 is also located between the wall portions on both sides of the eaves 4. For this reason, even if rainwater enters the ventilation space 13 and flows down from the opening 201, the rainwater can be received by the eaves 4.

  As shown in FIG. 2, a photovoltaic power generation panel 6 as a functional panel is provided on a roof surface constituted by a plurality of uneven roof materials 3. The photovoltaic power generation panel 6 converts solar energy into electric energy and outputs it by a semiconductor element mainly composed of silicon. The photovoltaic power generation panel 6 is placed across the upper surfaces of the plurality of convex portions 30. By placing the solar power generation panel 6 on the upper surface of the convex portion 30 in this manner, the solar power generation panel 6 can be cooled by outside air flowing through the ventilation space 13 inside the convex portion 30. The photovoltaic power generation panel 6 has a possibility that the power generation element becomes high temperature and the power generation efficiency (conversion efficiency) is lowered when the ambient atmosphere temperature is high or when direct sunlight is irradiated for a long time. However, in this embodiment, since the solar power generation panel 6 can be cooled by the outside air flowing through the ventilation space 13, a decrease in power generation efficiency of the solar power generation panel 6 can be suppressed.

  As described above, in the present embodiment, the side end portion of the covering portion 22 of the face door 2 provided on the eaves side of the uneven roof material 3 is directed from the side surface portion of the convex portion 30 of the uneven roof material 3 toward the concave portion 31 side. Thus, the blocking portion 220 protrudes. For this reason, rainwater that flows toward the eaves along the side surface of the recess 31 is blocked by the damming portion 220 at the eaves-side end of the recess 31 and then flows to the outdoor side. Accordingly, it is difficult for rainwater flowing through the concave portion 31 of the uneven roof material 3 to jump out to the outdoor side.

  Moreover, in this embodiment, the cover part 22 of the face door 2 is provided in the position corresponding to each of the adjacent convex part 30 of the uneven roof material 3, and is located between the adjacent convex parts 30 of these cover parts 22. Each of the side end portions on the concave portion 31 side is a blocking portion 220. Thereby, the blocking part 220 can be provided in the both sides in the eaves side edge part of the recessed part 31, and the rain water which flows through the recessed part 31 of the uneven roof material 3 becomes much more difficult to jump out to the outdoor side.

  Moreover, the cover part 22 of the face door 2 of this embodiment is wider than the convex part 30 of the uneven | corrugated roof material 3, and the both-ends part of the cover part 22 is from the corresponding side part of the convex part 30 to the recessed part 31 side. It protrudes toward the dam member 220. For this reason, the rain water flowing through the concave portions 31 on both sides of the cover portion 22 hardly jumps out to the outdoor side only by making the cover portion 22 wider than the convex portion 30.

(Second embodiment)
Next, a second embodiment different from the above will be described. In the following description of the second embodiment, the same components as those in the first embodiment are given the same numbers, and duplicate descriptions are omitted.

  The uneven roof material 3 of this embodiment is shown in FIG. 6, and is constructed as shown in FIG. The eaves side end portion of the bottom surface portion of each concave portion 31 of the uneven roof material 3 is an extended portion 310 that extends to the outdoor side from the convex portion 30. In the portion between the adjacent cover portions 22 in the plate-like portion 20 of each face door 2, the ridge side portion of the extension portion 310 of the corresponding uneven roof material 3 is placed. As shown in FIG. 5, the outdoor side portion of each extending portion 310 is folded back from the upper surface side of the draining portion 204 of the corresponding face door 2 to the lower surface side through the outdoor side, and the draining portion 204 is caught in this folded portion. The eaves side end of the uneven roofing material 3 is fixed to the plate-like portion 20 of the face door 2. That is, when the uneven roof material 3 is constructed, each extending portion 310 is inserted between the adjacent cover portions 22 as shown in FIG. 7, and thereafter, the outdoor side portion of each extending portion 310 is folded back. Then, the draining portion 204 is caught in the folded portion.

  As shown in FIG. 6, a seam 16 is formed between the end surfaces of the plate-like portions 20 of the adjacent doors 2 in the eaves-ridge direction. As shown in FIG. 5, the seam 16 is covered from the upper side over the eaves ridge direction by the corresponding extension portion 310 of the uneven roof material 3. Further, a portion corresponding to the drainage portion 204 in the joint 16 is also covered from below by an extension portion 310 that is folded back to the lower surface side of the drainage portion 204.

  As described above, the roof structure of the present embodiment includes the face doors 2 that are arranged side by side in the direction along the eaves, and each face door 2 has a bottom plate portion of the recessed portion 31 of the base plate 12 and the uneven roof material 3. It has the plate-shaped part 20 pinched | interposed between and the cover part 22 standingly arranged by the plate-shaped part 20. FIG. A plurality of face doors 2 are arranged in the eave direction. In addition, the uneven roof material 3 has an extending part 310 in which the bottom surface part of the recessed part 31 extends to the outdoor side from the projecting part 30, and between the adjacent plate-like parts 20 is covered from above by the extending part 310. ing. With this configuration, rainwater that flows from the concave portion 31 of the uneven roof material 3 to the outdoor side is less likely to leak from the seam 16 formed between the adjacent plate-like portions 20 to the eaves.

  In each of the above embodiments, the cover portion 22 of the face door 2 is formed in a trapezoidal shape, and both side surface portions of the convex portion 30 of the uneven roof material 3 are inclined so as to be positioned outward in the width direction of the convex portion 30. Yes. However, the cover part 22 is formed in a rectangular shape, and both side surface parts of the convex part 30 are formed so as to be orthogonal to the top surface part of the convex part 30, and the width of the cover part 22 is larger than the width of the convex part 30 in this. Thus, both end portions of the cover portion 22 may be used as the damming portion 220. Further, in each of the embodiments, both end portions in the width direction of the cover portion 210 are the damming portions 220, but only one side end portion may be the damming portion 220. Further, in each of the above embodiments, the side end portions on the concave portion 31 side of the cover portion 210 located on both sides of the concave portion 31 of the uneven roof material 3 are the damming portions 220, but the cover portion 210 located on one side of the concave portion 31. It is good also as the damming part 220 which protrudes only to the said recessed part 31 side. Moreover, in each said embodiment, although the functional panel was comprised with the photovoltaic power generation panel 6, you may comprise with the panel which has another function. The function panel can be omitted. Further, the present invention is applicable not only to a single-flow roof but also to roofs of other shapes such as a gable roof. In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
