Caps, although not shown, are provided at the upper ends of the second rising portions 45, 45 and the ridge-side joining portions 48, 48 of the adjacent surface members 37, 37, ..., 37a, 37a, ... Fitted or one of the second rising parts 45
Alternatively, the ridge-side joint 48 is formed to be long, and the tip of the ridge-side joint is folded downward to form a folded portion. It is an optional matter such as a structure to prevent rainwater from collecting between the upper end joints.
以上説明したように、本発明に係る金属防水屋根の棟納
め構造によれば、側部接合部を設けた面材を棟に沿っ
て、水密的、且つ気密的にシーム溶接することができた
ものである。As described above, according to the structure for housing the metal waterproof roof according to the present invention, the surface material provided with the side joints can be seam-welded along the ridge in a watertight and airtight manner. It is a thing.
すなわち、面材が単なる平板で形成されたものでは、そ

発明の第１の面材は２段構成の側部接合部の上端部を棟
側上方に行くにしたがって、先細り状になるように形成
している。However, in the case of the surface material provided with the two-sided side joints, the upper end of the second rising portion has a predetermined shape with respect to the ridge-side joint on the ridge side so that no gaps or breaks are formed. It is necessary to continuously mold while bending. In this respect, the first face material of the present invention is formed so that the upper end portion of the side joining portion having a two-stage structure is tapered toward the upper side of the ridge.
また、本発明の第２の面材は、２段構成の側部接合部の
上方段面部の先端を棟側に近づくにつれて幅広になり、
且つ下り傾斜して起端部で平板部に交わるように設ける
と共に、該上方段面部の先端側縁が第１立上げ部の起端
に交わるように形成している。In addition, the second face material of the present invention becomes wider as the tip of the upper step surface portion of the side joining portion having the two-step configuration becomes closer to the ridge side,
Further, it is provided so as to be inclined downward so as to intersect with the flat plate portion at the starting end portion, and the tip side edge of the upper step surface portion is formed so as to intersect with the starting end portion of the first rising portion.
したがって、側部接合部の上端と平板部の棟側側縁の間
が急激な折曲げや切れ目などないようにゆるやかな傾斜
により連続しているので、構成が簡潔で、しかも、側部
接合部の棟側の起端部において切れ目や隙間により雨漏
れが生じるおそれがない。Therefore, the space between the upper end of the side joint and the side edge of the flat plate on the ridge side is continuous with a gentle slope so that there are no sharp bends or breaks. There is no risk of rain leaks due to cuts or gaps at the ridge side of the building.
しかも、この面材の棟側上端部においては、棟側接合部
同志のシーム溶接をスムーズに行うことができ、棟部の
水密性と気密性を完全ならしめることができるものであ
る。Moreover, at the ridge-side upper end of this surface material, the seam welding of the ridge-side joints can be smoothly performed, and the water-tightness and air-tightness of the ridge can be perfectly achieved.

造。3. A metal face material comprising a two-sided side joining portion in which a first rising portion, an upper step surface portion, and a second rising portion are sequentially provided on both sides of a flat plate portion is laid on a base material of a roof. Then, in the metal waterproof roof configured by seam welding the second rising parts of the adjacent metal face materials, in the side part of the metal face material located on the ridge side, and close to the ridge part. Starting from the part, the side joint part of the two-stage structure is formed on the lower side, and the tip of the upper step surface part of the side joint part becomes wider as it approaches the ridge side, and the part is inclined downward. It is provided so as to intersect the flat plate portion at the end portion, and the tip side edge of the upper step surface portion is formed so as to intersect with the starting end of the first rising portion, and the second rising portion subjected to the seam welding further comprises: It is a side edge rising part that is continuous from the starting end to the ridge side part, and the ridge side end of the metal surface material is raised. The ridge-side joint of the metal facings that face each other through the ridge, after forming the ridge-side joint and starting up along the end of the side edge rising part that fell sideways. And a metal-sealed roof ridge-retracting structure, characterized in that the rising portions along the ridge are brought into contact with each other, and the rising portions located along the ridge are integrally seam-welded.

造。4. The metal surface material is provided with both side portions on the ridge side in parallel over a predetermined length in parallel to form a first parallel portion, and below the lower end of the first parallel portion, and Both sides are tapered outward to form a tapered portion over a predetermined length, and both sides below the tapered portion are provided in parallel to form a second parallel portion. Then, a valley fold line for forming a second rising portion and a side edge rising portion is formed in parallel to the second parallel portion and the tapered portion, and a portion where the first parallel portion and the tapered portion intersect with each other. A valley fold line for forming the lower edge of the first rising portion is formed below the valley fold line at the same position as seen in the longitudinal direction, starting from a portion inside the valley fold line and parallel to the second parallel portions on both side edges. Formed, at the same position in the longitudinal direction as the portion where the tapered portion and the second parallel portion intersect, and the valley Starting from a portion inside the ridge line, a parallel mountain fold line for forming the upper edge of the first rising portion is formed below the parallel line and parallel to the second parallel portion, and from the origin of the parallel mountain fold line to the first edge. 1 A taper mountain fold line for forming the upper edge near the ridge of the first rising portion is provided to the starting end of the valley fold line for forming the lower edge of the rising portion, and is parallel to the upper edge of the metal surface material. ,
5. A metal waterproof structure roof ridge for housing according to claim 3, further comprising a valley fold line which forms a rising portion for a ridge joint at an inner portion thereof and is bent along each of the fold lines. Construction.
