The outside that corresponds to the shape of the roof shingle having the shape of a mountain can be manufactured by an apparatus having the same structure as that of the roof shingle manufacturing apparatus 10 described above.
この第 2 実施例の屋根板 4 0 は、 段部 4 3 の幅が底部 から 山頂部にかけて全て均一になるため、 該部分にし わ 等が生ぜず、 絞り じわの 目立ちやすい樹脂皮膜処理を施 した鑼板を 用いて成形する場合に特に望ま しいばかり で な く 、 第 / 2 図に示した よ う に山部の横幅が全て等し い 場合には、 該山部に降下 した雨水がそのま ま山部の頂部 陵鎳に沿って直接下方に流れ落ち る ため、 該屋根板を固 定する ため に段部の直下における山部の部分に打ち付け た釘上に多 く の雨水が流下す る こ と となって、 該釕穴を 通しての雨水の洩れが生 じ る おそれがあ る が、 第 J 実施 例の屋根板 4 0 の山部 4 1 のよ う にテ ー ハ。形 と なって い る場合には、 上記 した よ う な雨水の洩れが生ずる可能性 が少ない。 すなわち 、 山部 4 1 のよ う に上方部分の曲率 半径が小さ く 、 下方部分の曲率半径が大 きい テ ー ハ。形 と した場合、 該山部 4 1 の曲率半径の小さ い上方部分に降 下 した雨水は、 山部の曲率半径が小さいために、 上記の 等幅山部のよ う に頂部陵線に沿ってそのま ま真直 ぐ下方 に流下せずに、 第 7 図に矢印で示すよ う に直ち に両側の 平坦部 4 2 に振分け落ち るこ と と な り 、 該山部 4 1 の下 方部分に降下し た限られた量の雨水のみ しか下方の山部 上におはる釘止め部上に流下 させ ないこ と と なる ので、 釘穴を通 し ての雨水の洩れ率を大幅に少な く する こ と が でき る と レ、 う勃果を有する。 In the roof plate 40 of the second embodiment, since the width of the step portion 43 is all uniform from the bottom to the top of the roof, a wrinkle or the like does not occur in the portion, and a resin film treatment in which the wrinkles are conspicuous is applied. Not only is it particularly desirable when forming using a gutter, but also if the width of the ridges is all equal as shown in Fig. 2, the rainwater that falls on the ridges is Since it flows down directly along the top ridge of the mountain, it is hit against the mountain immediately below the step to fix the roof shingle. A large amount of rainwater may flow down on the nails, which may cause rainwater to leak through the holes. 4 Tee as in 1. If it is shaped, it is unlikely that rainwater will leak as described above. That is, a wafer having a small radius of curvature in the upper portion and a large radius of curvature in the lower portion, such as the peak 41. In the case of the shape, the rainwater that falls to the upper part of the mountain part 41 with a small radius of curvature will fall along the top ridge like the above-mentioned equal width mountain part due to the small radius of curvature of the mountain part. As shown by the arrow in FIG. 7, it does not flow straight down, but immediately falls to the flat portions 42 on both sides, and the lower portion of the mountain portion 41 Since only a limited amount of rainwater that has fallen into the area will flow down onto the nailing part that falls on the lower mountain, the leakage rate of rainwater through the nail hole will be greatly reduced If they can be reduced, they will have eruptions.
