Modes for Carrying Out the Invention
[0010] Hereinafter, embodiments of the present invention will be described. Note that the following embodiments are only a part of various embodiments of the present invention. The following embodiments can be variously modified according to design and the like as long as the object of the present invention can be achieved.
[0011] (First Embodiment) 1. Overview As shown in FIG. 1, the building structure of this embodiment includes a roof material 8, a roof base 9, a base material 3, a cover material 2, and a water stop material 4. The roof materials 8 are provided on both sides of the building. The base material 3 is arranged on the roof base 9. The roof materials 8 are provided on this roof base 9. The cover material 2 covers the upper part of the building-side ends of the roof materials 8 on both sides of the building. The water stop material 4 is interposed between the roof material 8 and the base material 3 or the cover material 2 on both sides of the building.
[0012] The base material 3 includes a connecting portion 33, a base substrate portion 31, and a connecting portion 32. The connecting portion 33 is connected to the cover material 2 above the building-side end of the roof material 8. The base substrate portion 31 is arranged below the roof material 8. The connecting portion 32 connects the connecting portion 33 and the base substrate portion 31 on the building side.
[0013] The cover material 2 includes a cover portion 20, an extended portion 26, a cover substrate portion 27, and a folded-back portion 23. The cover portion 20 has a mountain-shaped cross section and has a pair of inclined pieces 22, 24 straddling above the building-side ends of the roof materials 8 on both sides of the building. The extended portion 26 is connected to one of the pair of inclined pieces 22, 24 of the cover portion 20. Also, the extended portion 26 is symmetrically arranged with respect to the connecting portion 32 and the building top 21. The cover substrate portion 27 is connected to the extended portion 26. Also, the cover substrate portion 27 is symmetrically arranged with respect to the base substrate portion 31 and the building top 21. The folded-back portion 23 is provided on the other of the pair of inclined pieces 22, 24 of the cover portion 20. Also, the folded-back portion 23 is connected to the connecting portion 33 of the base material 3.
[0014] In the building structure of this embodiment, on both sides of the building, since the water stop material 4 interposed between the roof material 8 and the base material 3 or the cover material 2 is in contact with the roof material 8, the gap between the base material 3 and the roof material 8 or the gap between the cover material 2 and the roof material 8 can be blocked by the water stop material 4, and it is possible to reduce the intrusion of water such as rainwater into the above gaps.
[0015] 2. Details Figure 1 shows the building structure of this embodiment. Although this building structure is for a residential building, the building structure of this embodiment is also applicable to non-residential buildings such as stores, factories, or warehouses. The building having the building structure of this embodiment forms a gable roof and has two roof surfaces sandwiching the ridge. In this embodiment, on each roof surface (the upper surface of the roofing material 8), the side where the ridge is located is defined as the "ridge side", and the side opposite to the ridge is defined as the "eaves side". Also, on each roof surface, the two directions, the direction from the ridge side towards the eaves side and the direction from the eaves side towards the ridge side, are the eaves-ridge directions. Note that the roof having the building structure of this embodiment is not limited to a gable roof.
[0016] The building structure of this embodiment uses a ridge member 1 including two members, a base material 3 and a cover material 2.
[0017] The base material 3 is made of sheet metal and is a long member extending along the ridge. The base material 3 has a base substrate portion 31, a connecting portion 32, and a connecting part 33.
[0018] As shown in FIG. 4B, the base substrate portion 31 is formed in a substantially flat plate shape. A reinforcing portion 34 is provided at the tip of the base substrate portion 31 (the end opposite to the connecting portion 32). The reinforcing portion 34 is formed by folding back on the upper surface side of the base substrate portion 31 by hemming or the like. The reinforcing portion 34 is formed over the entire length in the extending direction of the base substrate portion 31 (the direction parallel to the extending direction of the ridge). The base substrate portion 31 is reinforced by the reinforcing portion 34.
[0019] Also, the base substrate portion 31 has a plurality of protrusions 35. The plurality of protrusions 35 are each formed to protrude on the upper surface side of the base substrate portion 31. Also, the plurality of protrusions 35 are each formed over the entire length in the extending direction of the base substrate portion 31. The base substrate portion 31 is reinforced by the plurality of protrusions 35.
[0020] The connecting portion 32 is formed in a flat plate shape and is formed at one end of the base substrate portion 31 (the end portion on the side opposite to the reinforcing portion 34 and the end portion on the building side). Further, the connecting portion 32 is formed substantially perpendicular to the flat plate portion of the base substrate portion 31. Further, the connecting portion 32 is formed to rise on the upper surface side of the base substrate portion 31.
[0021] The connecting part 33 is formed in a flat plate shape and is provided at the upper end of the connecting part 32 (the end part on the side opposite to the base substrate part 31). The connecting part 33 is formed to be parallel to the base substrate part 31. In this specification, the term "parallel" includes not only strict parallelism but also "substantially parallel".
[0022] The connecting portion 32 connects the connecting portion 33 and the base substrate portion 31. The protruding length of the base substrate portion 31 from the connecting portion 32 is larger than the protruding length of the connecting portion 33 from the connecting portion 32. In other words, the protruding length of the connecting portion 33 from the connecting portion 32 is smaller than the protruding length of the base substrate portion 31 from the connecting portion 32.
[0023] The cover material 2 is made of sheet metal and is a long member extending along the building. As shown in FIG. 4A, the cover material 2 includes a cover portion 20 having a pair of inclined pieces 22, 24, a folded-back portion 23, a support portion 25, an extended portion 26, and a cover substrate portion 27.
[0024] The pair of inclined pieces 22, 24 are formed in a flat plate shape, and one ends thereof are connected at the building top 21. The pair of inclined pieces 22, 24 are formed to protrude obliquely downward from the building top 21. One inclined piece 22 and the other inclined piece 24 protrude in opposite left and right directions from the building top 21. Therefore, the cover portion 20 is formed in a cross-sectional mountain shape with the building top 21 as the apex.
[0025] The folded-back portion 23 is formed in a flat plate shape and is provided at one end of one inclined piece 22 (the end portion on the side opposite to the building top 21). The folded-back portion 23 is formed to be folded back from one end of the inclined piece 22 to the lower surface side.
[0026] The support portion 25 is formed in a flat plate shape and is provided at one end of the other inclined piece 24 (the end opposite to the ridge top portion 21). The support portion 25 is formed by folding back from one end of the inclined piece 24 toward the lower surface side.
[0027] The extending portion 26 is formed in a flat plate shape and is formed at one end of the support portion 25 (the end opposite to the end connected to the inclined piece 24). Also, the extending portion 26 is formed substantially perpendicular to the support portion 25. Further, the extending portion 26 stands up and is formed on the upper surface side of the cover substrate portion 27.
[0028] The cover substrate portion 27 is formed in a substantially flat plate shape. A reinforcing portion 28 is provided at the tip portion of the cover substrate portion 27 (the end opposite to the end connected to the extending portion 26). The reinforcing portion 28 is formed by folding back on the upper surface side of the cover substrate portion 27 by hemming or the like. The reinforcing portion 28 is formed over the entire length in the extending direction of the cover substrate portion 27 (the direction parallel to the extending direction of the building). The cover substrate portion 27 is reinforced by the reinforcing portion 28.
[0029] Also, the cover substrate portion 27 has a plurality of protrusions 29. The plurality of protrusions 29 are each formed so as to protrude on the upper surface side of the cover substrate portion 27. Also, the plurality of protrusions 29 are each formed over the entire length in the extending direction of the cover substrate portion 27. The cover substrate portion 27 is reinforced by the plurality of protrusions 29.
[0030] The building member 1 further includes a waterstop material 4. The waterstop material 4 is used as a packing or a sealing material and is formed of a standard and elastic material. As the waterstop material 4, for example, those formed of foamed rubber, polyvinyl chloride-based resin, chloroprene-based resin, ethylene propylene-based resin, silicone-based resin, EPDM, etc. can be used.
[0031] The water stop material 4 is formed in a prismatic shape, a strip shape, or the like, and as shown in FIG. 3, it is provided on the upper surface of the cover substrate portion 27 of the cover material 2. In this case, the water stop material 4 is provided between the reinforcing portion 28 and the protrusion 29 located closest to the side. Further, the water stop material 4 is provided over the entire length of the cover material 2 in the longitudinal direction.
[0032] Also, the water stop material 4 is provided on the upper surface of the base substrate portion 31 of the base material 3. In this case, the water stop material 4 is provided between the reinforcing portion 34 and the protrusion 35 located closest to the side. Further, the water stop material 4 is provided over the entire length of the base material 3 in the longitudinal direction.
[0033] And as shown in FIG. 3, the building member 1 can be formed by combining the cover material 2 and the base material 3. In this case, the connecting portion 33 of the base material 3 is inserted into the gap between one inclined piece 22 and the folded-back portion 23 of the cover material 2, and is adhered to the inclined piece 22 and the folded-back portion 23 with an adhesive or double-sided tape as necessary, whereby the connecting portion 33 is connected to the cover material 2.
[0034] Here, by sandwiching the connecting portion 33 using the elasticity of the inclined piece 22 and the folded-back portion 23, the connecting portion 33 can be connected to the cover material 2. In this case, it is not necessary to adhere the connecting portion 33 to the inclined piece 22 and the folded-back portion 23 with an adhesive or the like. Since the inclined piece 22 and the folded-back portion 23 are formed of a metal plate, they can be formed to have elasticity like a leaf spring, and the connecting portion 33 can be sandwiched and held between the inclined piece 22 and the folded-back portion 23 by this elastic force.
[0035] Also, the water stop material 4 provided on the cover substrate portion 27 and the base substrate portion 31 is not located below the pair of inclined pieces 22, 24, but is located outside the pair of inclined pieces 22, 24. That is, the water stop material 4 is located on the eaves side from the location where the connecting portion 33 of the base material 3 and the folded-back portion 23 of the cover material 2 are connected. Thereby, even if rainwater blows up, it is possible to suppress rainwater from entering from the connecting portion between the connecting portion 33 and the folded-back portion 23.
[0036] As shown in Fig. 2, the ridge member 1 is formed symmetrically about the center line L. Here, the center line L is a line parallel to the vertical line passing through the ridge top 21 of the cover material 2. Therefore, the connection part 32 between the extended part 26 of the cover material 2 and the base material 3 is located symmetrically with respect to the center line L (axis). Also, the cover substrate part 27 of the cover material 2 and the base substrate part 31 of the base material 3 are located symmetrically with respect to the center line L. Furthermore, the pair of left and right water stop materials 4 are located symmetrically with respect to the center line L.
[0037] And the ridge structure of this embodiment is constructed as follows. First, it is attached to the ridge member 1 at the part that becomes the ridge of the roof. In this case, the ridge member 1 is fixed to the roof base 9. The roof base 9 is formed by installing a sheathing board on a plurality of purlins (not shown) and laying an underlay material (waterproof sheet) on the sheathing board. The sheathing board is formed of plywood or the like, and the underlay material is, for example, a synthetic polymer-based underlay material or asphalt roofing (including asphalt felt and modified asphalt roofing).
[0038] The ridge member 1 is fixed to the roof base 9 by placing the cover substrate part 27 and the base substrate part 31 on the roof base 9 and fixing the cover substrate part 27 and the base substrate part 31 to the roof base 9 with fixtures such as nails or screws. The ridge member 1 is arranged so as to straddle the roof base 9 on both sides with the ridge part in between.
[0039] Next, a plurality of roof materials 8 are constructed on the roof base 9. The plurality of roof materials 8 are arranged, for example, in a staggered pattern. Also, the plurality of roof materials 8 are fixed to the roof base 9 with fixtures such as nails or screws. The roof material 8 is, for example, a slate tile, and is manufactured by molding a cement-based molding material and curing it.
[0040] Then, as shown in FIG. 1, the gable-side end of the roof member 8 located on the most gable side is connected to the gable member 1. The gable-side end of the roof member 8 located on one side across the gable portion (center line L) is inserted between the support portion 25 and the cover substrate portion 27 of the cover member 2. Further, the gable-side end of the roof member 8 located on the other side across the gable portion (center line L) is inserted between the folded-back portion 23 of the cover member 2 and between the connecting portion 33 of the base member 3 and the base substrate portion 31. Therefore, the gable-side end of the roof member 8 is located above the cover substrate portion 27 or the base substrate portion 31 and below the support portion 25, the folded-back portion 23, and the connecting portion 33.
[0041] Also, a waterproofing material 4 contacts the roof member 8 located on the most gable side. The waterproofing material 4 contacts the lower surface of the roof member 8. At this time, although the waterproofing material 4 is compressed in the thickness direction by the weight of the roof member 8, since it has elasticity, it adheres closely to the lower surface of the roof member 8. And, in the gable structure of the present embodiment, since the waterproofing material 4 is provided intervening between the upper surfaces of the cover substrate portion 27 and the base substrate portion 31 and the lower surface of the roof member 8, the waterproofing material 4 can block the gap between the upper surfaces of the cover substrate portion 27 and the base substrate portion 31 and the lower surface of the roof member 8 over the entire length in the longitudinal direction of the gable member 1, making it difficult for water such as rainwater to penetrate into the above gap from the eaves side.
[0042] (Second Embodiment) The gable structure according to the present embodiment is different from the gable member 1 according to the first embodiment in the configuration of the gable member 1A. Hereinafter, for the same configurations as those in the first embodiment, the same reference numerals will be given and the description will be appropriately omitted as necessary. The configurations described in the second embodiment can be applied in appropriate combination with the configurations described in the first embodiment.
[0043] As shown in FIG. 5, in the present embodiment, the gable member 1A is configured to include a cover member 5 and a pair of base members 6 and 7.
[0044] The cover member 5 is made of sheet metal and is a long member extending along the gable. As shown in FIG. 8A, the cover member 5 includes a cover portion 50 having a pair of inclined pieces 52 and 54 and a pair of folded-back portions 53 and 55.
[0045] The pair of inclined pieces 52 and 54 are formed in a flat plate shape, and one ends of them are connected at the ridge top portion 51. The pair of inclined pieces 52 and 54 are formed so as to project obliquely downward from the ridge top portion 51. One inclined piece 52 and the other inclined piece 54 project in opposite left and right directions from the ridge top portion 51. Therefore, the cover portion 50 is formed in a cross-sectional mountain shape with the ridge top portion 51 as the apex.
[0046] One folding portion 53 is formed in a flat plate shape and is provided at one end (the end opposite to the ridge top portion 51) of one inclined piece 52. This folding portion 53 is formed so as to fold back from one end of the inclined piece 52 toward the lower surface side.
[0047] The other folding portion 55 is formed in a flat plate shape and is provided at one end (the end opposite to the ridge top portion 51) of the other inclined piece 54. This folding portion 55 is formed so as to fold back from one end of the inclined piece 24 toward the lower surface side.
[0048] The pair of base materials 6 and 7 are made of sheet metal and are long members extending along the building. The base materials 6 and 7 each have a base substrate portion 61, 71, a connecting portion 62, 72, and a connecting portion 63, 73.
[0049] As shown in FIG. 8C, one base material 7 is formed in the same shape as the base material 3 of the first embodiment. That is, the base substrate portion 71 of the base material 7 is formed in a substantially flat plate shape. A reinforcing portion 74 is provided at the tip portion (the end opposite to the connecting portion 72) of the base substrate portion 71. The reinforcing portion 74 is formed by folding back on the upper surface side of the base substrate portion 71 by hemming or the like. The reinforcing portion 74 is formed over the entire length in the extending direction of the base substrate portion 71 (the direction parallel to the extending direction of the building). The base substrate portion 71 is reinforced by the reinforcing portion 74.
[0050] The base substrate portion 71 also has a plurality of protrusions 75. Each of the plurality of protrusions 75 is formed so as to protrude from the upper surface side of the base substrate portion 71. Further, each of the plurality of protrusions 75 is formed over the entire length of the base substrate portion 71 in the extending direction. The base substrate portion 71 is reinforced by the plurality of protrusions 75.
[0051] The connecting portion 72 is formed in a flat plate shape and is formed at one end of the base substrate portion 71 (the end portion on the side opposite to the reinforcing portion 74 and the end portion on the building side). Further, the connecting portion 72 is formed substantially perpendicular to the flat plate portion of the base substrate portion 71. Also, the connecting portion 72 is formed to rise on the upper surface side of the base substrate portion 71.
[0052] The connecting part 73 is formed in a flat plate shape and is provided at the upper end of the connecting part 72 (the end portion on the side opposite to the base substrate portion 71). The connecting part 73 is formed to be parallel to the base substrate portion 31.
[0053] The connecting portion 72 connects the connecting portion 73 and the base substrate portion 71. The protruding length of the base substrate portion 71 from the connecting portion 72 is larger than the protruding length of the connecting portion 73 from the connecting portion 72. In other words, the protruding length of the connecting portion 73 from the connecting portion 72 is smaller than the protruding length of the base substrate portion 71 from the connecting portion 72.
[0054] As shown in FIG. 8B, the other base material 6 has the same shape as the one base material 7 but is formed in a line-symmetric shape. The base substrate portion 61, the reinforcing portion 64, the protrusion 65, the connecting portion 62, and the connecting portion 63 of the other base material 6 respectively correspond to the base substrate portion 71, the reinforcing portion 74, the protrusion 75, the connecting portion 72, and the connecting portion 73 of the one base material 7.
[0055] Then, as shown in FIG. 7, the building member 1A can be formed by combining the cover material 5 and a pair of base materials 6 and 7. In this case, the connecting portion 73 of one base material 7 is inserted into the gap between one inclined piece 54 and the folded-back portion 55 of the cover material 5, and is adhered to the inclined piece 54 and the folded-back portion 55 with an adhesive or double-sided tape as needed, whereby the connecting portion 73 is connected to the cover material 2. Further, the connecting portion 63 of the other base material 6 is inserted into the gap between the other inclined piece 52 and the folded-back portion 53 of the cover material 5, and is adhered to the inclined piece 52 and the folded-back portion 53 with an adhesive or double-sided tape as needed, whereby the connecting portion 63 is connected to the cover material 2.
[0056] Here, by sandwiching the connecting portions 63 and 73 using the elasticity of the inclined pieces 52 and 54 and the folded-back portions 53 and 55, the connecting portions 63 and 73 can be connected to the cover material 5. In this case, it is not necessary to adhere the connecting portions 63 and 73 to the inclined pieces 52 and 54 and the folded-back portions 53 and 55 with an adhesive or the like. Since the inclined pieces 52 and 54 and the folded-back portions 53 and 55 are formed of a metal plate, they can be formed to have elasticity like a leaf spring, and the connecting portions 63 and 73 can be sandwiched and held by the elastic force of the inclined pieces 52 and 54 and the folded-back portions 53 and 55.
[0057] Also, the waterstop material 4 is provided on the lower surfaces of the respective one folded-back portion 55 and the other folded-back portion 53 of the cover material 5. The waterstop material 4 is located above the pair of base substrate portions 61 and 71. That is, the waterstop material 4 is located on the eaves side from the location where the connecting portions 63 and 73 of the base materials 6 and 7 and the folded-back portions 53 and 55 of the cover material 5 are connected. Thereby, even if rainwater blows up, it is possible to suppress the intrusion of rainwater from the connecting portion between the connecting portions 63 and 73 and the folded-back portions 53 and 55.
[0058] As shown in Fig. 6, the ridge member 1A is formed symmetrically about the center line L. Here, the center line L is a line parallel to the vertical line passing through the ridge top 51 of the cover material 5. Therefore, the base material 6 and the base material 7 are symmetrically located with respect to the center line L as a reference (axis). That is, the connecting portion 63 of the base material 6 and the connecting portion 73 of the base material 7 are symmetrically located with respect to the center line L. Also, the connecting portion 62 of the base material 6 and the connecting portion 72 of the base material 7 are symmetrically located with respect to the center line L. Further, the base substrate portion 61 of the base material 6 and the base substrate portion 71 of the base material 7 are symmetrically located with respect to the center line L. The pair of left and right water stop materials 4 are symmetrically located with respect to the center line L.
[0059] And the ridge structure of this embodiment is constructed as follows. First, it is attached to the ridge member 1A at the portion that becomes the ridge of the roof. In this case, the ridge member 1A is fixed to the roof base 9. The ridge member 1 is placed on the roof base 9 with the base substrate portions 61 and 71, and is fixed to the roof base 9 by fixing tools such as nails and screws for the base substrate portions 61 and 71, so that it is fixed to the roof base 9. The ridge member 1 is arranged so as to straddle the roof bases 9 on both sides with the ridge portion in between.
[0060] Next, a plurality of roof materials 8 are constructed on the roof base 9. The plurality of roof materials 8 are arranged, for example, in a staggered pattern. Also, the plurality of roof materials 8 are fixed to the roof base 9 by fixing tools such as nails and screws.
[0061] And as shown in Fig. 5, the ridge side end of the roof material 8 located closest to the ridge is connected to the ridge member 1. The ridge side end of the roof material 8 located on one side with the ridge portion (center line L) in between is inserted between the folded-back portion 53 of the cover material 5 and the connecting portion 73 and the base substrate portion 71 of the base material 7. Also, the ridge side end of the roof material 8 located on the other side with the ridge portion (center line L) in between is inserted between the folded-back portion 55 of the cover material 5 and the connecting portion 63 and the base substrate portion 61 of the base material 6. Therefore, the ridge side end of the roof material 8 is located above the base substrate portions 61 and 71 and below the folded-back portions 53 and 55 and the connecting portions 63 and 73.
[0062] Further, the waterproofing material 4 contacts the roof material 8 located on the most gable side. The waterproofing material 4 contacts the upper surface of the roof material 8. At this time, although the waterproofing material 4 is compressed in the thickness direction, since it has elasticity, it adheres closely to the upper surface of the roof material 8. And in the gable structure of the present embodiment, since the waterproofing material 4 is interposed between the lower surfaces of the folded-back portions 53 and 55 of the cover material 5 and the upper surface of the roof material 8, the gaps between the lower surfaces of the folded-back portions 53 and 55 and the lower surfaces of the connecting portions 63 and 73 and the upper surface of the roof material 8 can be blocked over the entire length in the longitudinal direction of the gable member 1A, making it difficult for water such as rainwater to penetrate into the above gaps from the eaves side.
[0063] (Modification example) The embodiments described above can be appropriately modified in design.
[0064] The above embodiment is one in which the gable structure according to the present invention is applied to a large gable, but it is not limited thereto, and it may be applied to a corner gable.

The base material 3 includes a connecting portion 33 connected to the cover material 2 above the gable-side end of the roof material 8, a base substrate portion 31 disposed below the roof material 8, and a connecting portion 32 connecting the connecting portion 33 and the base substrate portion 31 on the gable side. The cover material 2 includes a cover portion 20 having a mountain-shaped cross-section with a pair of inclined pieces 22 and 24 straddling above the gable-side ends of the roof materials 8 on both sides of the gable, an extending portion 26 connected to one of the pair of inclined pieces 22 and 24 of the cover portion 20 and symmetrically arranged with respect to the connecting portion 32 and the gable top 21, a cover substrate portion 27 connected to the extending portion 26 and symmetrically arranged with respect to the base substrate portion 31 and the gable top 21, and a folded-back portion 23 provided on the other of the pair of inclined pieces 22 and 24 of the cover portion 20 and connected to the connecting portion 33 of the base material 3.
[0066] According to this aspect, the gap between the base material 3 or the cover material 2 and the roofing material 8 can be blocked by the water stop material 4, making it difficult for water to penetrate into the above gap, and thus having excellent waterproof performance.
[0067] The building structure according to the second aspect includes roofing materials 8 provided on both sides of the building, a pair of base materials 6 and 7 arranged on the roof base 9 where the roofing materials 8 are provided, a cover material 5 covering the upper part of the building-side ends of the roofing materials 8 on both sides of the building, and water stop materials 4 interposed between the roofing materials 8 and the base materials 6, 7 or the cover material 5 on both sides of the building. The pair of base materials 6 and 7 are symmetrically arranged with respect to the building top 51. The pair of base materials 6 and 7 each include connecting portions 63 and 73 connected to the cover material 5 above the building-side ends of the roofing materials 8, base substrate portions 61 and 71 arranged below the roofing materials 8, and connecting portions 62 and 72 connecting the connecting portions 63 and 73 and the base substrate portions 61 and 71 on the building side. The cover material 5 includes a cover portion 50 having a cross-sectional mountain shape with a pair of inclined pieces 52 and 54 straddling the upper part of the building-side ends of the roofing materials 8 on both sides of the building, and folding-back portions 53 and 55 connected to the connecting portions 63 and 73 of the base materials 6 and 7 respectively on each of the pair of inclined pieces 52 and 54 of the cover portion 50.
[0068] According to this aspect, the gap between the base material 3 or the cover material 2 and the roofing material 8 can be blocked by the water stop material 4, making it difficult for water to penetrate into the above gap, and thus having excellent waterproof performance.
[0069] The third aspect is that in the building structure according to the first or second aspect, the water stop material 4 is located on the eaves side from the location where the connecting portion 33 (63, 73) of the base material 3 (6, 7) and the folding-back portion 23 (53, 55) of the cover material 2 (5) are connected.
[0070] According to this aspect, even if rainwater blows up, the water stop material 4 can suppress the intrusion of rainwater from the connection location between the connecting portion 33 (63, 73) and the folding-back portion 23 (53, 55).
