A large number of circular air holes 15 are formed in the closing portion 9 over the entire length in the eave direction.

  The side piece portions 10 are provided at both end portions in the eave direction of the closing portion 9. Each side piece 10 protrudes upward from the edge in the eave direction of the closing portion 9 and is orthogonal to the eave direction. Each side piece 10 is formed over the entire length of the closing portion 9 in the eaves-ridge direction. In addition, although the vent hole 15 is not formed in each side piece part 10 of the example of illustration, you may form the vent hole 15.

  As shown in FIG. 2, a plurality of uneven roof materials 11 are placed side by side in the eaves direction on the base plate 5. As shown in FIG. 1, the eaves side portion of each uneven roof material 11 is placed on the base plate 5 via the placing piece portion 7 of the closing member 6.

  Each uneven roof material 11 is made of a steel plate. In addition, each uneven | corrugated roof material 11 may be formed with metal plates other than a steel plate, and the material is not limited to a metal. The uneven roof material 11 has a convex portion 12 that opens downward and protrudes upward, and a concave portion 13 that opens upward and is recessed downward. A plurality of convex portions 12 and concave portions 13 are alternately formed in the eaves direction. The side surface portion of each convex portion 12 also serves as the side surface portion of the adjacent concave portion 13. The side surface portion is perpendicular to the upper surface portion of the convex portion 12.

  As shown in FIG. 3, the adjacent uneven roof material 11 is connected via a connector 14 provided on the base plate 5. A concave portion 13 is formed at an end portion of each uneven roof material 11 on the side of the connector 14.

Engaged portions 19 are formed on both side surfaces of each cover member 18. The engaged portions 19 on both sides of each cover member 18 are engaged with the hooked portions 16 of the corresponding uneven roof material 11. Accordingly, each cover member 18 is attached to the connector 14 via the uneven roof material 11. The part between the adjacent uneven roof materials 11 and the connector 14 arranged here are covered from above by a cover member 18.

  As shown in FIG. 1, a ventilation space 20 is formed between the base plate 5 and each uneven roof material 11 disposed thereon. The ventilation space 20 is a space surrounded by the convex portion 12 and the base plate 5 and is formed in the same number as the convex portion 12 in the eave direction. Each ventilation space 20 is formed in a rectangular shape in a cross section orthogonal to the eaves-ridge direction, and is formed over substantially the entire length of the uneven roof material 11 in the eaves-ridge direction.

  The eaves-side end of each uneven roof material 11 constitutes a margin portion 21 that protrudes more outdoors than the eaves-side edge of the field board 5 in the eaves-ridge direction. The convex part 12 in the allowance part 21 of each uneven | corrugated roof material 11, ie, the edge part of the eaves side of each convex part 12, is opening below. Each convex part 12 in these allowance parts 21 constitutes an introduction part 22 for introducing outside air (outdoor air) into the corresponding ventilation space 20. That is, outside air is introduced into the ventilation space 20 from the inside of the introduction section 22 having a groove shape in cross section. Further, as shown in FIG. 4, the lead-out portion 23 of the ventilation space 20 is configured by the ridge-side end portion of the convex portion 12 of the uneven roof material 11 and the opening surrounded by the field plate 5. That is, the air introduced into the ventilation space 20 from the introduction portion 22 is discharged to the outside from the outlet portion 23 after passing through the ventilation space 20. A ridge cover 34 is provided in the ridge 4. The ridge cover 34 hides the lead-out part 23 and suppresses rainwater and the like from entering the ventilation space 20 from the lead-out part 23.

  As shown in FIG. 1, the closing portion 9 that protrudes to the outdoor side of the closing member 6 is located below the protruding portion 21 of each uneven roof material 11. The closing portion 9 is parallel to the lower surface of the recessed portion 13 in the allowance portion 21. The closing portion 9 is opposed to each convex portion 12 and each concave portion 13 in the protruding portion 21 of each uneven roof material 11. In addition, the air holes 15 of the closing portion 9 are respectively formed at locations corresponding to the convex portions 12 and the concave portions 13 of the uneven roof materials 11.

  Here, the closing portion 9 is arranged to be spaced downward from the lower surface of each recess 13 in the protruding portion 21 of each uneven roof material 11. A gap 24 communicating with the inner space of each introduction portion 22 is formed between the closing portion 9 and the allowance portion 21. The gap 24 is composed of a space 25 between the lower opening of each introduction portion 22 and the closing portion 9 facing this, and a space 26 between the lower surface of each recess 13 and the closing portion 9 facing this. Has been. Adjacent spaces 25 communicate with each other through a space 26 therebetween, and the gap 24 is formed over the entire length of the closing portion 9 in the eave direction. Both ends of the gap 24 are closed by the side piece 10 of the closing member 6. The inner space of each introduction portion 22 communicates with the lower side of the closing portion 9 through the gap 24 and the vent hole 15. Thereby, outside air is introduced into each ventilation space 20 through the ventilation hole 15, the gap 24, and the introduction part 22 in this order.

  At the eaves side end of each uneven roofing material 11, the outdoor side of the space between the allowance portion 21 and the closing portion 9, that is, the outdoor side of the gap 24 and the outdoor side of the inner space of each introduction portion 22 is blocked. A closing member 27 is attached. The closing member 27 extends over the entire length of each uneven roof material 11 in the eave direction. In addition, the closure member 27 may be comprised with the member provided side by side in the eaves direction, and may be integrally formed over the eaves direction.

  The closing member 27 has a plate-like closing portion 29 orthogonal to the eaves-ridge direction. The closing part 29 is composed of a lower cover part 30 and an upper cover part 31. The lower cover part 30 is formed in a plate shape long in the eave direction. A plurality of upper cover portions 31 are formed in the lower cover portion 30 with an interval in the eave direction. Each upper cover portion 31 protrudes upward from a position corresponding to each convex portion 12 in the lower cover portion 30, and is formed in a rectangular shape that is substantially the same shape as the convex portion 12 when viewed from the eaves-ridge direction. Each upper cover part 31 is arrange | positioned at the eaves side edge part of the corresponding convex part 12, and has block | closed the outdoor side of the inner side space of the said introducing | transducing part 22. FIG.

  The lower cover portion 30 is disposed along the outdoor side edge of the closing portion 9. The lower cover portion 30 is in contact with the outdoor side edge of the closing portion 9 or is disposed in the vicinity of the outdoor side edge of the closing portion 9. The outdoor side of the gap 24 is blocked at the upper part of the lower cover part 30. In this way, the blocking member 27 blocks the outdoor side of the gap 24 and the outdoor side of each introduction portion 22, so that rainwater or the like hardly enters the ventilation space 20 from the introduction portion 22 or the gap 24. Further, the closing portion 9 of the closing member 6 is arranged so as to close the space between the lower covering portion 30 and the field plate 5. For this reason, it can suppress that rainwater, a small bird, an insect, etc. enter the ventilation space 20 side by the blocking part 9. FIG. Further, the lower portion of the lower cover portion 30 protrudes below the closing portion 9. The projecting portion 28 functions as a guide for guiding outside air below the closing portion 9 to the closing portion 9 side, so that outside air is easily introduced into the ventilation space 20 through the ventilation hole 15.

  As shown in FIG. 1, an eaves basket 32 is provided along the eaves part 2 on the outdoor side of the eaves part 2. The eaves bar 32 is attached to the surface of the eaves part 2 on the outdoor side via a fixture (not shown). The eaves 32 is provided at a position to receive rainwater that has flowed out from the upper surface of each uneven roofing material 11 to the outdoor side. The eaves 32 is located below the lower edge of the blocking portion 29 and the closing portion 9. For this reason, rainwater directly adhering to the outdoor side of the closed portion 29 or rainwater flowing along the surface from the upper surface of the uneven roof material 11 to the outdoor side of the closed portion 29 falls on the eaves wall 32 and is received by the eaves wall 32. It is like that. Further, when rainwater enters each ventilation space 20, the rainwater discharged from each ventilation hole 15 of the closing portion 9 can be received by the eaves 32.

  As shown in FIG. 2, a photovoltaic power generation panel 35 as a functional panel is provided on a roof surface composed of a plurality of uneven roof materials 11. The photovoltaic power generation panel 35 converts solar energy into electric energy and outputs it by a semiconductor element mainly composed of silicon. The solar power generation panel 35 may be a double-sided light receiving panel that can receive power from both the upper and lower surfaces and generate power, or may be a panel that can generate power by receiving light only from the upper surface.

  The photovoltaic power generation panel 35 is provided across the plurality of uneven roof materials 11. As shown in FIG. 3, a bolt 36 that protrudes upward from the cover member 18 is provided in any of the connectors 14 that connect the uneven roof materials 11 to each other. The photovoltaic power generation panel 35 is fixed on the roof surface using these bolts 36.

  As shown in FIG. 2, the photovoltaic power generation panel 35 is placed across the upper surfaces of the plurality of convex portions 12. By placing the solar power generation panel 35 on the upper surface of the convex portion 12 in this way, the solar power generation panel 35 can be cooled by outside air flowing through the ventilation space 20 inside the convex portion 12. In the photovoltaic power generation panel 35, when the ambient atmosphere temperature is high, or when direct sunlight is irradiated for a long time, the power generation element may become high temperature and the power generation efficiency (conversion efficiency) may be reduced. However, in the present embodiment, the photovoltaic power generation panel 35 can be cooled by the outside air flowing through the ventilation space 20, so that a decrease in power generation efficiency of the photovoltaic power generation panel 35 can be suppressed.

  In addition, a ventilation space 37 surrounded by the solar power generation panel 35 and the concave portion 13 of the concave and convex roof material 11 is formed between the solar power generation panel 35 and the concave and convex roof material 11 positioned below the solar power generation panel 35. Hereinafter, the ventilation space 20 is referred to as a first ventilation space 20, and the ventilation space 37 is referred to as a second ventilation space 37.

  The number of the second ventilation spaces 37 is the same as the number of the recesses 13 closed by the solar power generation panel 35. Each second ventilation space 37 is formed over the entire length of the photovoltaic power generation panel 35 in the eaves-ridge direction.

  An eaves side end 38 of each second ventilation space 37 is open to the eaves side. In addition, as shown in FIG. 4, the ridge side end 39 of each second ventilation space 37 is open to the ridge side. Thus, by opening the eaves side and the ridge side of each second ventilation space 37, outside air is introduced into each second ventilation space 37 from the eaves side end portion 38, and this outside air is introduced through the second ventilation space 37 to the ridge side. It can be discharged from the end 39. For this reason, the solar power generation panel 35 can also be cooled by outside air passing through each second ventilation space 37. The outside air in each second ventilation space 37 is easy to flow from the eaves side toward the ridge side. This is because the wind hitting the uneven roof material 11 inclined downward toward the eaves side tends to flow toward the building side, and natural convection toward the building side occurs in each second ventilation space 37.

  In the roof structure of the present embodiment described above, the uneven roof material 11 is provided on the field plate 5, and the first ventilation space 20 is formed between the convex portion 12 and the field plate 5. For this reason, sufficient air permeability between the field board 5 and the uneven roofing material 11 can be ensured through the outside air through the first ventilation space 20. In addition, the uneven roofing material 11 has a protruding portion 21 that protrudes more outward than the eaves side edge of the base plate 5 in the eaves ridge direction, and the first ventilation space from the inside of the protruding portion 12 in the protruding portion 21. Outside air is introduced into 20. For this reason, the outside air that has reached the inside of the introduction portion 22 from the vent hole 15 side can be guided to the ridge side by the upper surface portion of the convex portion 12 in the outlet portion 21. Therefore, the air permeability of the first ventilation space 20 can be further enhanced. Further, a closing portion 9 having a vent 15 is provided below the allowance portion 21. For this reason, rainwater, a small bird, an insect, etc. become difficult to enter into the 1st ventilation space 20 side.

  Further, the closing portion 9 is arranged to be spaced downward from the lower surface of the concave portion 13 of the uneven roof material 11, and the closing portion 9 has a ventilation hole 15 in each of a location corresponding to the convex portion 12 and a location corresponding to the concave portion 13. Is formed. For this reason, compared with the case where the closing part 9 contact | abuts to the lower surface of the recessed part 13, the air permeability of the 1st ventilation space 20 can be improved. In other words, in the present embodiment, the closing portion 9 is arranged so as to be spaced downward from the lower surface of the concave portion 13, so that the outside air corresponds not only from the vent hole 15 formed at the location corresponding to the convex portion 12 but also to the concave portion 13. The first ventilation space 20 is also introduced from the ventilation holes 15 formed at the locations. In this case, the outside air that has passed through the vent hole 15 formed at a location corresponding to the concave portion 13 is a space 26 between the concave portion 13 and the closing portion 9, a space 25 between the convex portion 12 and the closing portion 9, and an introduction portion. 22 will be introduced into the first ventilation space 20 through the space inside. Thereby, the pressure loss when the outside air passes through the blocking portion 9 and is introduced into the first ventilation space 20 is reduced, and the outside air is easily introduced into the first ventilation space 20. Therefore, sufficient air permeability of the first ventilation space 20 can be secured while suppressing the protruding length of the protruding portion 21 of the uneven roof material 11 from the field plate 5. In addition, by suppressing the protruding length of the protruding portion 21, it is possible to receive rainwater flowing from the uneven roof material 11 and the like with the eaves wall 32 while suppressing an increase in the width of the eaves wall 32 in the indoor and outdoor directions.

  In the present embodiment, a closed portion 29 that closes the outdoor side of the space between the protruding portion 21 and the closed portion 9 is provided at the eaves side end portion of the uneven roof material 11. For this reason, it becomes difficult for rainwater or the like to enter the first ventilation space 20 via the introduction portion 22. Moreover, in this embodiment, the closing part 9 is formed in the shape of a piece parallel to the lower surface of the recessed part 13 of the uneven roof material 11. For this reason, a space 26 having a uniform vertical width can be formed between the closing portion 9 and the lower surface of the upper concave portion 13. Therefore, the pressure loss when the outside air passes through the space 26 can be reduced, and the air permeability of the first ventilation space 20 can be enhanced.

(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.

  In the present embodiment, as shown in FIG. 5, the closing portion 9 of the closing member 6 is inclined with respect to the lower surface of the recessed portion 13 of the uneven roof material 11. The closing portion 9 is inclined so as to gradually approach the lower surface of the recess 13 as it goes to the outdoor side, and is substantially horizontal. The outdoor side edge of the closing part 9 is in contact with the upper end part of the indoor side surface of the lower cover part 30 of the closing member 27 or is arranged in the vicinity of the upper end part of the same surface.

  Thus, the closing part 9 of this embodiment is formed in the shape of a piece inclined with respect to the lower surface of the recessed part 13 of the uneven roofing material 11. For this reason, compared with the case where it parallels with the lower surface of the recessed part 13 like 1st embodiment, the area of the blocking part 9 in which the vent hole 15 is formed is suppressed, suppressing the protrusion amount of the blocking part 9 to the outdoor side. Can be increased. For this reason, while suppressing the protrusion amount of the protruding part 21 of the uneven roof material 11, the opening area of the ventilation hole 15 in the closing part 9 can be sufficiently secured, and the air permeability of the first ventilation space 20 can be enhanced.

  In the present embodiment, the closing portion 9 is inclined so as to gradually approach the lower surface of the recess 13 as it goes to the outdoor side, but is inclined so as to gradually move away from the lower surface of the recess 13 as it goes to the outdoor side, etc. The design can be changed as appropriate.

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

  In the present embodiment, as shown in FIG. 6, the closing portion 9 of the closing member 6 is positioned below the eaves side end portion of the field plate 5. In addition, the closing member 6 has a second closing portion disposed so as to close the space between the eaves side end portion of the base plate 5 and the indoor side end portion of the closing portion 9 disposed below this. Hereinafter, the closing portion 9 is referred to as a first closing portion 9.

  The side piece 8 in the present embodiment extends downward from the eaves side end of the base plate 5, and the side piece 8 constitutes a second closing portion. A large number of circular second vent holes 41 are formed over the entire length in the eaves direction at a portion of the side piece 8 (second blocking portion) protruding downward from the base plate 5. That is, the second ventilation hole 41 is formed at a position corresponding to both the convex portion 12 and the concave portion 13 of the uneven roof material 11 in the second closing portion. The first closing portion 9 projecting from the lower edge of the side piece 8 (second closing portion) to the outdoor side is in contact with the lower end portion of the indoor side surface of the lower covering portion 30 of the closing member 27 or the same. It arrange | positions in the vicinity of the surface lower end part.

  As described above, the first closing portion 9 of the present embodiment is located below the eaves side end portion of the field plate 5. Further, a side piece portion 8 (second blocking portion) having a second ventilation hole 41 is provided so as to block between the eaves side end portion of the field plate 5 and the indoor side end portion of the first closing portion 9. For this reason, the gap 24 between the closing portion 9 and the allowance portion 21 can be communicated with the space between the side piece portion 8 and the eave portion 2 via the second ventilation hole 41. For this reason, the pressure loss at the time of external air being introduce | transduced into the 1st ventilation space 20 can be made small, and the air permeability of the 1st ventilation space 20 can be improved.

  In the present embodiment, the first closing portion 9 is parallel to the lower surface of the recess 13, but may be inclined with respect to the lower surface of the recess 13 as in the second embodiment. Moreover, in each said embodiment, although the functional panel was comprised with the photovoltaic power generation panel 35, 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.
