【００１４】ａはタイトフレーム（図面なし）の頂部に
直立状に突設した本発明の剣先ボルトであり、以下の構
成からなっている。A is a sword-point bolt of the present invention protruding upright at the top of a tight frame (not shown), and has the following structure.
【００１５】１は前記ボルトａを構成する頭部、２は前
記頭部１の上方に形成されているシャンク、３は前記シ
ャンク３の上方に所定の長さをもって突設したねじ部で
ある。Reference numeral 1 denotes a head constituting the bolt a; 2, a shank formed above the head 1; and 3, a threaded portion projecting above the shank 3 with a predetermined length.
【００１６】４はねじ部３の上方部に、ねじ部４の外径
より若干径が小さいか、あるいはねじ部３の内径と同程
度の径にして、且多角柱形状に形成した上方突出部であ
る。５は前記上方突出部４を構成する各側壁面である。An upper protruding portion 4 is formed on the upper portion of the screw portion 3 so that the diameter is slightly smaller than the outer diameter of the screw portion 4 or the diameter is approximately the same as the inner diameter of the screw portion 3. It is. 5 is each side wall surface which comprises the said upper protrusion part 4. FIG.
【００１７】本発明は、前記各側壁面５の２面が寄り合
って接合する角部を従来の剣先ボルトを構成した上方突
出部の各側壁面の尖状角部と全く異なって、角部の角を
おとし、丸味をつけた。６は前記各側壁面５の角部に丸
味をつけた湾曲部である。According to the present invention, the corners at which the two side walls 5 are brought into contact with each other are completely different from the pointed corners of the side walls of the upwardly protruding portion which constitutes the conventional pointed bolt. The corners were rounded and rounded. Numeral 6 denotes a curved portion in which a corner of each side wall surface 5 is rounded.
【００１８】本発明の剣先ボルトａの成型は、従来の剣
先ボルトの成型と異なっている。The formation of the sword bolt a of the present invention is different from the formation of the conventional sword bolt.
【００１９】従来の前記剣先ボルトを構成するねじ部の
上方に突設する上方突出部を構成する各側壁面が寄り合
って形成される角印が尖状となっていた。The square marks formed by the side wall surfaces forming the upper protruding portion projecting above the screw portion forming the conventional pointed bolt have a pointed shape.
【００２０】７は前記上方突出部４の上方部に形成した
尖状部８を有する円錐形状の剣先部である。９は廻り止
め部である。Reference numeral 7 denotes a conical sword having a pointed portion 8 formed above the upper protruding portion 4. Reference numeral 9 denotes a detent portion.
【００２１】１１は本発明剣先ボルトａによって穿設さ
れた折版屋根材１０に形成の孔、１２は前記孔１１の周
辺のバリである。Reference numeral 11 denotes a hole formed in the folded roof material 10 formed by the sword bolt a of the present invention, and 12 denotes burrs around the hole 11.
【００２２】１２’は前記孔１１の周辺の切れ目であ
る。Reference numeral 12 'denotes a cut around the hole 11.

側壁面５が寄り合う個所が、湾曲状となっているので、
均等にかかって前記孔１１を開ける。その孔１１の開け
時に発生するバリ１２の高さが稍均一となる。さらに前
記孔１１の周辺の切れ目１２’も均一となる。When the sword-point bolt a of the present invention punches the folded roof material 10 into a hole 11, the sword-point part 7 projects upward from the sword-point part 7.
Since the hitting action force that has reached the point where the side wall surfaces 5 constituting the upper protruding portion 4 come close to each other is curved,
The holes 11 are opened evenly. The height of the burr 12 generated when the hole 11 is opened becomes slightly uniform. Further, the cut 12 'around the hole 11 becomes uniform.
【００２４】しかし、従来の剣先ボルトは、その成型時
において、上方突出部を構成する各側壁面の角部を尖状
にするために、成型時に大きな圧力をかけないと、確実
に側壁面の角部を尖状に成型することができなかった。
従って前記のように成型時の圧力を大きくすることによ
って、消費エネルギーが大となり、これが原因で製造費
がアップせざるを得なかった。However, in the conventional sword bolt, the corners of the side walls constituting the upwardly projecting portion are sharpened at the time of molding. The corners could not be formed into pointed shapes.
Therefore, as described above, by increasing the pressure at the time of molding, energy consumption is increased, and the production cost has to be increased due to this.
【００２５】さらに、従来のタイトフレームに取着した
剣先ボルトは、施工時において前記ボルトの上方に位置
する折版屋根材に叩き具を介し孔を開けると、バリの高
さにバラツキが生じ均一にならない弊害があった。Furthermore, when a conventional sword bolt attached to a tight frame is drilled with a tapping tool through a folded roof material located above the bolt at the time of construction, the height of the burrs varies, and the uniformity occurs. There was an adverse effect.
【００２６】また孔が開けられた際の切れ目も、均一化

目の不揃えがもとでシールパッキンが完全に被覆できず
雨漏りする原因にもなっていた。Also, the cuts when the holes were made were not uniform, but were long and short, and were not aligned. Due to the unevenness of the cuts, the seal packing could not be completely covered, causing a leak.
【００２７】請求項２記載の発明に関する実施の形態を

【００２９】即ち図３（Ａ）より湾曲部６の径が若干大
きい径の図３（Ｂ）のように形成する。That is, the curved portion 6 is formed as shown in FIG. 3B having a diameter slightly larger than that of FIG.
【００３０】本発明の剣先ボルトａは、上方突出部４が
前記のように角部ではなく、湾曲部６を有する形状なの
で、成型する際の圧力が、従来の成型時の圧力よりも、
小さくとも十分対応し成型が可能である。The pointed bolt a of the present invention has a shape in which the upper protruding portion 4 has the curved portion 6 instead of the corner portion as described above, so that the molding pressure is lower than the conventional molding pressure.
It can be molded even if it is small enough.
【００３１】従って製品コストを従来品より著減し、且
生産性を著しく高めた。Therefore, the product cost was significantly reduced as compared with the conventional product, and the productivity was significantly improved.
