It is attached to the tool 8. The cover member 15 covers the part between the uneven roof materials 11 on both sides and the connector 8 arranged here from above.

  As shown in FIG. 1, a ventilation space 17 is formed between the base plate 4 and each uneven roof material 11 arranged thereon. Each ventilation space 17 is a space surrounded by the convex portion 12 and the base plate 4, and is formed in the same number as the convex portion 12 along the eaves direction D2. The ventilation space 17 is formed to have a rectangular cross section in a cross section perpendicular to the eave building direction D1, and is formed over the entire length of the uneven roof material 11 in the eave building direction D1.

  The eaves-side end of the uneven roofing material 11 is a margin 18 that is located on the outdoor side of the eaves-side end edge of the base plate 4 in the eaves-ridge direction D1. The convex part 12 (namely, the edge part of the eaves side of each convex part 12) in the allowance part 18 of the uneven roof material 11 is opened below. The lower opening of each convex part 12 in the margin part 18 is formed in a rectangular shape that is long in the eaves-ridge direction D1, and this lower opening part constitutes the inlet 19 of the corresponding ventilation space 17.

  As shown in FIGS. 1 and 4, the eaves-side rear guide plate 5, the cover plate 6, and the ridge-side guide plate 7 are sandwiched between the corresponding uneven roof material 11 and the field plate 4, and the field plate 4 is fixed.

  As shown in FIG. 1, a plate-shaped rear guiding portion 20 that protrudes downward along the eaves side end surface of the field plate 4 is formed at the eaves side edge of the eaves side rear guiding plate 5. The rear guiding portion 20 is formed over the entire length of the eaves direction rear guiding plate 5 in the eave direction D2. The lower end portion of the rear guiding portion 20 protrudes below the eaves side end surface of the field plate 4. A lower portion of the protruding portion is a bent portion 21 bent outward. The bent portion 21 functions as a drainer.

  The eaves side portion of the cover plate 6 protrudes more outward than the eaves side rear guide plate 5 in the eave building direction D1. This projecting portion constitutes the cover portion 22 and is disposed so as to cover the introduction port 19 below the protruding portion 18 of each uneven roof material 11. A number of intake holes 24 are formed in the cover portion 22 at portions that overlap the respective inlets 19. Thus, by providing the cover portion 22 having a large number of intake holes 24 at the introduction port 19, rainwater, small birds, insects, and the like do not easily enter the ventilation space 17.

  A plate-like edge piece 25 is provided at the eaves side end of the cover portion 22 so as to be substantially parallel to the rear guiding portion 20 so as to protrude downward. The surface on the outdoor side of the edge piece 25 is disposed at substantially the same position as the eaves-side end surface of the uneven roof material 11 in the eave building direction D1.

  An eaves side guide plate 26 that is substantially orthogonal to the eave building direction D1 is attached to the eaves side end of the uneven roof material 11 over the entire length of the eaves direction D2 of the uneven roof material 11. The eaves side guide plate 26 may be configured by a plurality of members arranged side by side in the eave direction D2, or may be integrally formed over the eave direction D2.

  The eaves side guide plate 26 has a guide portion 27 in the lower portion and a plurality of closed portions 28 in the upper portion. The guide portion 27 is fixed to the outer surface of the edge piece portion 25 of the cover plate 6 (that is, the surface of the edge piece portion 25 opposite to the surface facing the rear guide portion 20 side). The lower end portion of the guide portion 27 protrudes below the edge piece portion 25.

  The guiding portion 27 faces the rear guiding portion 20, and a space 29 is formed between the guiding portion 27 and the rear guiding portion 20. The space 29 is a space that opens downward and communicates with the ventilation space 17 through the air intake hole 24. The lower end portion of the guide portion 27 functions as a drainer.

  A plurality of blocking portions 28 are formed in the eaves portion 27 with an interval in the eaves direction D2. Each blocking portion 28 has a shape in which a part of the guide portion 27 in the eave direction D2 extends upward, and is formed in a rectangular shape that is substantially the same shape as the convex portion 12 when viewed from the outdoor side in the eaves direction D1. Has been. Each closing part 28 is arranged so as to close the end opening on the eaves side of the corresponding convex part 12.

  The outdoor air is introduced into each ventilation space 17 through the space 29 between the rear guiding portion 20 and the guiding portion 27 and the intake hole 24 (introduction port 19) in this order. In this case, the air that has entered the space 29 from the lower side rises along the outdoor side surface of the rear guide unit 20 and the indoor side surface of the guide unit 27 and is guided to the intake hole 24 (inlet 19). The The air introduced to the ventilation space 17 through the intake hole 24 is discharged from a later-described outlet 32 which is an end opening on the ridge side of the ventilation space 17. Thereby, favorable air permeability is ensured between the field board 4 and the uneven roofing material 11.

  As shown in FIG. 1, an eaves basket 31 is provided along the eaves part 2 on the outdoor side of the eaves part 2. The eaves 31 is installed at a position for receiving rainwater that flows out from the upper surface of each uneven roofing material 11 to the outdoor side. More specifically, the eaves bowl 31 is provided below the introduction port 19 of each ventilation space 17, the lower end portion of the rear guide portion 20, and the lower end portion of the guide portion 27 of the eaves side guide plate 26. It is installed to be located. Thereby, when rainwater enters each ventilation space 17, rainwater discharged from the intake hole 24 of the cover portion 22 can be received by the eaves 31. In addition, rainwater that has dropped from the lower end portion of the rear guiding portion 20 and the lower end portion of the guiding portion 27 can be received by the eaves 31.

  On the other hand, the ridge side end of each uneven roofing material 11 is disposed at a position that is further on the eaves side than the ridge side end surface of the base plate 4 as shown in FIG. The outlet 32 of the ventilation space 17 is constituted by the ridge side end of the convex portion 12 of the uneven roof material 11 and the opening surrounded by the base plate 4. The outlet 32 of each ventilation space 17 opens toward the ridge side on the field board 4.

  The ridge side portion of the ridge side guide plate 7 protrudes toward the ridge side with respect to the uneven roof material 11, and this protruding portion constitutes the guide portion 33. The ridge side portion of the guide portion 33 is a bent portion 34 that is bent upward, and the bent portion 34 is positioned to face the outlet 32 of the ventilation space 17. The protruding direction of the bent portion 34 is inclined to the ridge side with respect to the direction orthogonal to the base plate 4, and the air discharged from each ventilation space 17 easily flows to the ridge side by this inclination. .

  A ridge cover 36 extending in the ridge direction D3 of the field board 4 is attached to the ridge 3. The ridge part cover 36 may be composed of a plurality of members arranged side by side in the ridge direction D3, or may be integrally formed across the ridge direction D3.

  The ridge part cover 36 is attached to the ridge part 3 via a plurality of fixtures 37 so that a gap is formed between the ridge part 3 and the ridge part 3. The ridge cover 36 includes a vertical plate portion 38 that forms an outdoor surface, a horizontal plate portion 39 that forms an upper surface, and a side plate portion 40 (see FIG. 2) that forms a side end surface.

  The horizontal plate portion 39 protrudes from the upper end portion of the vertical plate portion 38 toward the eaves side, and is substantially parallel to the eaves-ridge direction D1. The horizontal plate portion 39 is disposed above the field plate 4, the uneven roof material 11, and the ridge side guide plate 7. A space 41 communicating with each outlet 32 is formed between the horizontal plate portion 39 and the guide portion 33. A space 42 communicating with the eaves side of the space 41 is formed between the horizontal plate portion 39 and the uneven roof material 11. A protruding piece 43 that protrudes downward is formed at the eaves side end of the horizontal plate portion 39 over the ridge direction D3. An opening 44 is formed between the lower end portion of the projecting piece portion 43 and the uneven roof material 11 located on the lower side. The space 42 opens toward the eaves side through the opening 44. That is, the outlet 32 of each ventilation space 17 communicates with the opening 44 via the space 41 and the space 42 located in the vicinity of the ridge side end of the uneven roof material 11.

  The vertical plate portion 38 is substantially parallel to the outdoor side surface of the ridge portion 3. A space 45 communicating with the space 41 is formed between the vertical plate portion 38 and the ridge portion 3. The space 45 opens downward through a vent 46 formed between the lower end of the vertical plate portion 38 and the ridge 3.

  As shown in FIG. 5A, when a wind blows from the eave side to the ridge side, this wind is received by the rear guiding portion 20 and guided to the introduction port 19 side, and the inside of each ventilation space 17 is built from the eave side to the ridge side. Flows to the side. On the other hand, when the wind blows from the ridge side toward the eaves side, as shown in FIG. 5 (b), the wind is blown into the eaves bowl 31 from above, and rises along the inner surface of the eaves bowl 31. It is guided along the guide 20 to the introduction port 19 side, and flows in the ventilation spaces 17 from the eaves side to the building side. That is, in the ventilation space 17, an air flow usually occurs from the eaves side toward the ridge side. The air discharged from the outlet 32 of each ventilation space 17 is discharged to the lower side of the ridge cover 36 through the space 41, the space 45, and the ventilation hole 46.

  By the way, when the wind blows from the building side toward the eave side as shown by the arrow a1 in FIG. 4, the wind hits the outer wall surface on the building side of the building 1 and then the building 1 of the building 1 as shown by the arrow b1. It rises along the outer wall surface on the side, and is then introduced into the space 45 from the vent 46. The air introduced into the space 45 is exhausted from the opening 44 through the space 41 and the space 42 in order. At this time, in the upper portion of the space 41 located in the vicinity of the ridge side end of the uneven roof material 11, a negative pressure is generated by the passage of air and acts to draw air from the ventilation space 17. Due to this negative pressure, an air flow from the eaves side toward the ridge side is likely to occur in each ventilation space 17.

  In the present embodiment, as shown in FIG. 2, a photovoltaic power generation panel 48 as a functional panel is provided on a roof surface constituted by a plurality of uneven roof materials 11. The solar power generation panel 48 converts solar energy into electric energy and outputs it by a semiconductor element mainly made of silicon. The solar power generation panel 48 may be a double-sided light receiving panel that can receive power from both the upper and lower surfaces and generate power, or a panel that can receive light from only the upper surface and generate power.

  As shown in FIG. 4, the ridge side end portion of the photovoltaic power generation panel 48 is disposed in the vicinity of the eave side end portion of the horizontal plate portion 39 of the ridge portion cover 36. The ridge-side end surface of the photovoltaic power generation panel 48 faces the protruding piece 43 of the ridge cover 36, and an air derivation gap 53 is formed between the protruding piece 43.

  As shown in FIG. 3, the arbitrary connecting tool 8 that connects the uneven roof materials 11 is provided with a bolt 49 protruding upward from the cover member 15. The photovoltaic power generation panel 48 is fixed on the roof surface using these bolts 49.

  As shown in FIG. 4, the photovoltaic power generation panel 48 is placed on the upper surfaces of the plurality of convex portions 12 and straddles the plurality of convex portions 12. For this reason, the 2nd ventilation space 52 is formed between the photovoltaic power generation panel 48 and the uneven | corrugated roofing material 11 located under this. The second ventilation space 52 is a space surrounded by the solar power generation panel 48 and the concave portion 13 of the uneven roof material 11, and is formed in the same number as the concave portions 13 closed by the solar power generation panel 48. The 2nd ventilation space 52 is formed so that it may become a cross-sectional rectangular shape in the cross section orthogonal to the eaves-ridge direction D1. The second ventilation space 52 is formed over the entire length of the photovoltaic power generation panel 48 in the eaves-ridge direction D1.

  As shown in FIG. 2, the end opening 50 on the eaves side of the second ventilation space 52 is located near the center in the eaves ridge direction D <b> 1 of the uneven roof material 11. As shown in FIG. 4, the end opening 51 on the ridge side of the second ventilation space 52 is located slightly on the eaves side with respect to the lateral plate portion 39 of the ridge cover 36 in the eave building direction D1, and the gap 53 and the opening 44.

  In the second ventilation space 52, air easily flows from the eaves side toward the ridge side. This is because the wind hitting the uneven roofing material 11 inclined downward toward the eave side tends to flow toward the ridge side. The air exhausted from the end opening 51 of the second ventilation space 52 passes through the opening 42, the space 42, the space 41, and the space 45 in the ridge cover 36 in order, and then passes through the ventilation port 46. It is discharged to the lower side of the part cover 36. When the air discharged from the second ventilation space 52 passes through the upper portion of the space 41, a negative pressure is generated in the upper portion of the space 41, and the air is drawn from the ventilation space 17. The negative pressure at this time also tends to cause an air flow from the eave side to the building side in each ventilation space 17.

  By the way, the photovoltaic power generation panel 48 has a possibility that the power generation element becomes high temperature and the power generation efficiency (conversion efficiency) is lowered when the ambient temperature is high or when direct sunlight is irradiated for a long time. However, in this embodiment, by providing the ventilation space 17 and the second ventilation space 52 below the photovoltaic power generation panel 48 as described above, the photovoltaic power generation is performed by the air flowing through the ventilation space 17 and the second ventilation space 52. The panel 48 can be cooled and the temperature rise of the photovoltaic power generation panel 48 can be suppressed. Therefore, a decrease in power generation efficiency of the solar power generation panel 48 is suppressed.

  The overall structure of the roof structure according to the present embodiment has been described in detail with reference to FIGS. Below, the structure and procedure for fixing the uneven roof material 11 to the field board 4 are explained in full detail based on FIGS.

  As described above, the eaves side guide plate 26 is provided with the plurality of closed portions 28 protruding upward so as to correspond one-to-one with the plurality of convex portions 12 of the uneven roof material 11. That is, the upper part of the eaves side guide plate 26 is provided in an uneven shape that is substantially the same shape as when the uneven roofing material 11 is viewed from the outdoor side in the eaves building direction D1, and the uneven portion 55 is defined as the closed portion 28. Yes. The concave and convex portion 56 formed on the eaves side guide plate 26 is a portion corresponding to the concave portion 13 of the concave and convex roofing material 11 on a one-to-one basis. In the eaves side guide plate 26, the concave portion 56 and the convex portion 55 are provided. They are alternately formed in the eaves direction D2. The side edge portion of each convex portion 55 also serves as the side edge portion of the adjacent concave portion 56.

  As shown in FIG. 6, each convex part 55 which is rectangular has the to-be-latched piece 57 extended toward the outdoor side of the eaves-ridge direction D1 in the upper end edge and both-sides edge. A similar locked piece 57 is extended to the lower end edge of the recess 56 toward the outdoor side. Specifically, an eaves side guide plate 26 whose upper part is substantially uneven is formed using a plate member made of a plastic material, and slits are formed in the substantially uneven corners of the upper part of the eaves side guide plate 26. The notched piece 57 is formed by providing the notch 58 and bending the portion between the adjacent notches 58 outward. Of the upper part of the eaves side guide plate 26, a part other than the locked piece 57 serves as a closing plate 54 that is arranged in a plurality with a distance in the eaves direction D2.

  On the other hand, as shown in FIG. 6, a plurality of slit-shaped cutouts 60 are provided at the eaves end portion of the uneven roof material 11 toward the indoor side in the eaves-ridge direction D1. Specifically, notches 60 are respectively formed at the upper and lower corners of both side edges in the eaves direction D2 of the eaves tip portions of the convex portions 12 of the uneven roof material 11. A portion between adjacent notches 60 in the eaves tip of the uneven roofing material 11 becomes a foldable bent piece 61. The cut-out dimension of each notch 60 (that is, the projecting dimension of the bent piece 61 toward the outdoor side in the eave building direction D1) is set larger than the projecting dimension of the locked piece 57 toward the outdoor side.

  These bent pieces 61 include an upper bent piece 61 extending from the upper end of each convex portion 12 to the outdoor side of the eave building direction D1, and a house in the eave building direction D1 from both side ends of each convex portion 12. It consists of bent pieces 61 on both sides that extend outward, and lower bent pieces 61 that extend from the lower end of each recess 13 to the outdoor side of the eaves direction D1. The upper bent piece 61 corresponds to the locked piece 57 extending from the upper end edge of the closing plate 54 of the eaves side guide plate 26 on a one-to-one basis. The bent pieces 61 on both sides correspond one-to-one with the locked pieces 57 extending from both side edges of the closing plate 54. The lower bent piece 61 corresponds one-to-one with the locked piece 57 extending from the lower end edge of the concave portion 56 of the eaves-side guide plate 26.

  When the uneven roofing material 11 is fixed to the eaves-side guide plate 26, first, as shown in FIG. The uneven roof material 11 is arranged on the eaves-side guide plate 26 so that the inserted occlusion plate 54 closes the eaves-side opening of the ventilation space 17. At this time, the bent pieces 61 of the uneven roof material 11 overlap each other in the thickness direction with respect to the corresponding locked pieces 57, and further, the front end edge of each bent piece 61 is the locked piece. It arrange | positions so that it may protrude rather than the front-end | tip edge of 57. FIG. In addition, the notch 60 formed in the uneven roof material 11 is disposed so that the indoor end of the notch 60 extends further to the indoor side than the locked piece 57.

  Next, each bent piece 61 of the uneven roof material 11 made of a plastic material is bent so as to wind the corresponding locked piece 57. That is, as shown by the arrows in FIG. 8, the upper bent piece 61 extending from the convex portion 12 of the uneven roof material 11 is bent toward the locked piece 57 that overlaps the lower bent piece 61, and the bent portion is bent. The piece 61 is engaged with the locked piece 57. Similarly, the bent pieces 61 on both sides extending from the convex portion 12 of the uneven roofing material 11 are bent toward the locked pieces 57 that overlap on the inside, and the bent piece 61 is bent. 57 is engaged. Further, the lower bent piece 61 extending from the concave portion 13 of the uneven roofing material 11 is bent toward the locked piece 57 that overlaps below, and the bent piece 61 is bent. Engage with.

  With this structure, the uneven roof material 11 is fixed to the eaves side guide plate 26 as shown in FIG. Eventually, the uneven roof material 11 is firmly fixed to the field board 4 through the eaves side guide plate 26, the cover plate 6 and the eaves side rear guide plate 5. According to this structure, even when a load such as a strong wind is applied to the eaves, it is possible to prevent the eaves portion of the uneven roof material 11 from turning up and coming off due to the load, and to generate an abnormal noise with the flap. Further, when the uneven roof material 11 is fixed to the base plate 4, there is no need to fix the concave portion 13 of the uneven roof material 11 to the base plate 4 with screws, nails or the like, and the water finish is improved. In addition, according to this structure, the uneven roofing material 11 having the convex portions 12 and the concave portions 13 alternately along the eave direction D2 can be prevented from being bent after being fixed. Furthermore, since the structure of the eaves tip edge of the uneven roof material 11 is a structure in which the bent piece 61 is bent, the small edge portion of the uneven roof material 11 is also prevented from being exposed to the eaves edge.

  Furthermore, in this embodiment, the same fixing structure is provided also in the cover member 15 which covers the part between the uneven | corrugated roof materials 11 adjacent from the upper side. That is, as shown in FIG. 6 and FIG. 7, the above-described bending is performed from the eaves side front end portion of the upper wall portion of the cover member 15 and the eave side front end portions of the engaged portions 16 that the cover member 15 has on both sides. A bent piece 62 similar to the piece 61 is extended toward the outdoor side in the eaves-ridge direction D1.

  This cover member 15 is also covered from the upper side with respect to the corresponding closing part 28. At this time, the upper bent piece 62 included in the cover member 15 overlaps with the upper locked piece 57 included in the closing portion 28, and the bent pieces 62 on both sides included in the cover member 15 are included in the locked pieces 57 on both sides. And overlap. The cover members 15 are fixed to the corresponding closing portions 28 by bending the respective bent pieces 62 of the cover member 15 inward and engaging the corresponding engaged pieces 57 so as to be wound. As a result, the cover member 15 is fixed to the field board 4 through the eaves side guide plate 26, the cover plate 6, and the eaves side rear guide plate 5. Since the structure of the front edge of the eaves of the cover member 15 is a structure in which the bent piece 62 is bent, it is possible to prevent the edge portion of the cover member 15 from being exposed to the eaves.

  As described above in detail with reference to the drawings, the roof structure of the present embodiment is provided with the uneven roof material 11 on the field board 4. The uneven roof material 11 has convex portions 12 that open downward and concave portions 13 that open upward alternately in the eaves direction D <b> 2, and forms a ventilation space 17 between the convex portions 12 and the field board 4. A closed portion 28 that is inserted into the convex portion 12 and closes the eave side of the ventilation space 17 is fixed to the eave side end portion of the base plate 4, and the uneven roof material 11 is fixed to the closed portion 28. .

  According to this structure, it is possible to enhance the air permeability by the ventilation space 17 formed by using the uneven roof material 11, and the uneven roof material 11 has the blocking portion 28 that closes the eaves side of the ventilation space 17. It is fixed to the field board 4 via. Therefore, even when a load such as a strong wind is applied to the eaves, the uneven roofing material 11 can be firmly fixed so that the eaves part of the uneven roofing material 11 does not come off due to the load or abnormal noise is generated. it can. In addition, it is not necessary to fix the concave portion 13 of the uneven roof material 11 to the base plate 4 with screws, nails or the like, and the water finish is improved. Furthermore, the uneven roof material 11 having the convex portions 12 and the concave portions 13 alternately can be prevented from being bent after being fixed.

  Moreover, in the roof structure of this embodiment, the uneven roof material 11 has a plurality of cutouts 60 at the eaves side end of the convex portion 12, and the bent pieces 61 formed between the adjacent cutouts 60 are disposed inside. By folding the folded piece 61 into the closed portion 28, the bent piece 61 is fixed to the closed portion 28. According to this structure, the eaves of the uneven roof material 11 has a structure in which the bent piece 61 is bent, and the fore edge portion of the eaves of the uneven roof material 11 is suppressed from being exposed.

  Further, the closing portion 28 includes a closing plate 54 that closes the eaves side of the ventilation space 17, and a locked piece 57 that protrudes from the peripheral portion of the closing plate 54 toward the outdoor side. When the locked piece 57 is engaged with the curved piece 61, the closed portion 28 and the uneven roof material 11 are fixed. According to this structure, the uneven roof material 11 can be fixed to the closed portion 28 by a simple operation of bending the folded piece 61 of the uneven roof material 11 so as to be wound around the locked piece 57.

  As mentioned above, although this invention was demonstrated based on embodiment shown to an accompanying drawing, this invention is not limited to the said embodiment. For example, in the present embodiment, the functional panel is configured by the solar power generation panel 48, but may be configured by a panel having other functions, or the functional panel may 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. For other configurations, appropriate design changes can be made within the range intended by the present invention.
