  The horizontal roof material 1 is a horizontal roof material. The roof material 1 is press-formed with a metal such as a galvalume steel plate and a color stainless steel plate having excellent corrosion resistance. This roofing material 1 has several lengths (for example, 6, 9, 12, etc.) in the longitudinal direction, and a step portion 2 is formed by folding back at a predetermined pitch.

  A pair for connecting the roofing material 1 adjacent to each other in the vertical direction to the upper and lower ends in the figure, which are both ends of the inclined direction (short direction perpendicular to the longitudinal direction) when the roofing material 1 is installed on the roof. Incline directions 10 and 20 are provided. The upper end of the tilt direction is provided with a bottom 10 in the tilt direction (hereinafter may be simply referred to as “lower 10”), and the lower end is the top 20 in the tilt direction (hereinafter simply referred to as “upper 20”). May be provided)

  As shown in FIGS. 3 to 5, the lower shell 10 includes a first folding part 11 and a second folding part 12. The first folded portion 11 is formed by folding the upper end in the inclined direction to the surface side. The second folded portion 12 is formed by folding the first folded portion 11 further outward in the tilt direction. Moreover, the lower edge 10 is further turned back to the inner side as a water return 13. “Water return” is a ridge provided to dam the water flowing on the roof tile such as rainwater. The upper shell 20 has a first folded portion 21 (third folded portion) formed by folding the lower end in the inclined direction to the back surface side. Further, the upper edge 20 of the upper shell 20 is folded back further outward as a water return 22.

  As shown in FIG. 1, the roof material 1 has a pair of longitudinal directions 30 and 40 for connecting the roof materials 1 adjacent to each other in the left and right direction at the left and right ends in the figure, which are both ends in the longitudinal direction. Have. In the present embodiment, the right end is provided with a bottom 30 in the longitudinal direction (hereinafter sometimes simply referred to as “lower 30”), and the left end is provided with a longitudinal 40 in the longitudinal direction (hereinafter simply referred to as “upper”). 40 ").) Is provided.

  As shown particularly in FIGS. 3 and 4, the longitudinal bottom 30 is provided at the right end, which is one side end of the roofing material 1. The lower shell 30 has a first folding part 31 and a second folding part 32. The first folded portion 31 is formed by folding the right end in the longitudinal direction to the surface side of the roof material 1. The second folded portion 32 is formed by folding the first folded portion 31 further outward in the longitudinal direction. Further, the lower shell 30 is folded back further inward as the water return 33 to the front side.

  The first folded portion 31 has a notched portion 34 that has a lower end that is one side end in the inclined (short) direction and is notched so as to be inclined so that the right end is longer in the width direction of the first folded portion 31. This notch 34 forms a part of the first folded portion 21 of the shell 20 in the inclination direction. That is, a part of the longitudinal side at the lower end, which is the one side end of the first folded portion 31 of the shell 30 in the longitudinal direction, is folded back to the back side of the roofing material 1 and the top of the shell 20 in the inclined direction. It is formed as one folded portion 21 (third folded portion). In other words, the first folded portion 31 of the bottom 30 in the longitudinal direction is folded back together with the first folded portion 21 for forming the bottom 20 in the inclined direction.

  Due to the thickness of the roofing material 1, the thickness d as shown in FIG. 4 is actually formed when the flange 20 is folded back to the back side in the inclination direction. A part of the notch 34 that is folded back together with the flange 20 in the inclined direction is located in the range of the thickness d. In other words, the connection position 35 where the cutout portion 34 is connected to the right end of the first folded portion 31 of the shell 30 in the longitudinal direction is formed within the thickness range of the first folded portion 21 of the shell 20 in this inclined direction. It will be.

  The width of the first folded portion 31 in the longitudinal direction of the roof material is the width excluding the width of the notched portion 34 folded together with the first folded portion 21 of the shell 20 in the inclined direction, but the longitudinal direction of the shell 40 in the longitudinal direction. It is preferable that it is larger than the width.

  As shown particularly in FIGS. 5 and 6 (a part of the shell 20 is omitted in FIG. 6), the shell 40 is provided at the left end which is the other end side of the roof material 1 in the longitudinal direction. The upper shell 40 has a first folded portion 41 that is folded back to the back surface side. From the viewpoint of workability when the first folded portion 41 is hung on the bottom 30, a slope 43 is formed in the folded width direction at the top of the top 40 in the slanted direction.

  Next, the procedure when the roofing material 1 is installed on the side will be described with reference to FIGS. In FIGS. 7 and 8, the hide line of the left roof material 1a is indicated by a dotted line, and the hide line of the roof material 1b is indicated by a one-dot chain line.

  The left roof material 1a and the right roof material 1b are installed on a roof base plate (not shown). The left roofing material 1a is in a state in which it is connected to a roofing material (not shown) that has already been installed by being hooked in the longitudinal direction. In addition, on the slope direction, the seam 20a is hung on the other roof material (not shown) installed below the slope direction, and the left roof material 1a is on the roof material below the seam 20a on the slope direction. It is in a state of overlapping. Further, the roof materials adjacent to the lower side and the upper side in the inclination direction are arranged in a staggered manner so that the joint portions, which are portions where the top 30 and the top 40 are overlapped, are not overlapped in the longitudinal direction. Furthermore, the left roofing material 1a is fixed to a structurally effective field and rafters by screws, screws, and nails (not shown) at a plurality of places in the bottom 10a in the inclined direction.

  In this state, as shown in FIG. 7, on the longitudinal direction of the right roofing material 1b, the bottom 40b is hung on the bottom of the left roofing material 1a on the bottom of the left roofing material 1a, and the right roofing material 1b slides upward from below. Is done. Since the top 40b is provided with the slope 43, it can be easily multiplied even if there is a folded notch 34a. As shown in FIG. 8, when the right roofing material 1 b is slid to a predetermined position, the right roofing material 1 b is engaged with the fixing 20 b on the inclination direction of the right roofing material 1 b and fixed on the left roofing material 1 a.

  Here, the width of the first folded portion 31a in the longitudinal direction is higher than the width folded back together with the first folded portion 21 of the shell 20a, and the top is larger than the width in the longitudinal direction of the shell 40b. For this reason, when the top 40b is hooked and slid, the notch 34a does not affect the operation of sliding the top 40b and the sliding operation, and work when connecting the adjacent roofing materials 1a and 1b. Can be improved.

  The roofing material 1 thus connected becomes a roofing material excellent in waterproofness and drainage when installed on the roof. The effect of the roofing material 1 in this embodiment is demonstrated using the roofing material as a comparative example.

  FIG. 9 is a side view roofing material 100 as a comparative example, and is a plan view showing a gap 101 in particular in the lower longitudinal direction.

  The horizontal roof material 100 is formed by sliding a vertical space (not shown) of another roof material, which is hung on the vertical space 101, from the lower end portion in the inclined direction toward the upper end portion. Are connected to each other.

  In the longitudinally lower bottom 101, a first folded portion 102 is formed in which the right end in the longitudinal direction is folded back to the surface side, and then a second folded portion 103 is further folded back outward in the longitudinal direction. The first folded portion 102 has a notch 104 that is notched in the inclination direction.

  The notch 104 is cut so that the length in the inclination direction of the first folded portion 102 is shorter than the lower end in the inclination direction of the roof material 100 in order to improve workability when the adjacent roof materials 100 are overlapped. It is a missing part.

  Such a recumbent roofing material 100 is formed with such a cutout portion 104 so that the first folded portion 102 does not interfere when sliding with a hull.

  However, the roof material 100 has a drawback that water such as rainwater enters the back side of the roof material 100. That is, water such as rainwater penetrates to the back surface of the roof material 100 without flowing in the eave direction after reaching the longitudinal end (the right end of the first folded portion 102) along the outer edge of the notch 104. End up. As a result, the roofing material 100 having the first folded portion 102 and the notch 104 has a structural problem that causes water leakage (rain leakage).

  Further, when the lower right end of the bottom is folded back in the longitudinal direction together with the bottom as in Patent Document 1 described above, the fold becomes a bag shape, and water such as rainwater accumulates therein.

  On the other hand, the side roof material 1 in the present embodiment has the notch portion 34 folded back to the back side together with the top 20. Further, the folded portion of the cutout portion 34 is within the thickness range of the first folded portion 21 of the top 20. For this reason, the water transmitted through the notch 34 is finally transmitted onto another roof material arranged below the roof material 1a, and flows down to the eaves as it is along the inclination direction. That is, water does not accumulate in the folds, or is transmitted from the roofing material 1 to the back surface side, and further water does not enter the roof.

  Such a horizontal roofing material 1 in this embodiment is excellent in waterproofness (watertightness) in the connection part of the roofing material adjacent to a longitudinal direction, and can prevent permeation of water, such as rain water. Further, even when the notch 34 is folded back together with the flange 20 in the inclination direction, the folded portion does not become an obstacle when connecting and connecting adjacent roof materials, and the roof has excellent workability. The material 1 can be realized.

  Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the device. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the invention described in the claims of the utility model registration and the equivalent scope thereof.

  For example, the cutout portion 34 that is folded back together with the first folded portion 21 of the top 20 may be folded back to the back surface of the roof material 1. That is, the connection position 35 between the cutout portion 34 and the right end side of the first folded portion 31 may be located on the back surface of the roofing material 1. Even in this case, water flows along the notch 34 and does not accumulate in the bag-like fold, so that a roofing material excellent in waterproofness and drainage can be realized.

  Moreover, the outer edge of the notch 34 may be linear or curved.
