Description
本発明は、折板構造や波板構造の屋根に取り付けることができる親綱張設具に関するものである。 The present invention relates to a master rope tensioning tool that can be attached to a roof having a folded plate structure or a corrugated plate structure.
作業者が屋根に上がって高所作業を行う際には、落下事故を未然に防止するために、屋根に沿って張り渡された親綱に命綱を引っ掛けて作業が行われる。 When an operator goes up to the roof and works at a high place, in order to prevent a fall accident, the work is performed by hooking a lifeline on a master rope stretched along the roof.
例えば、特許文献１には、命綱が引っ掛けられる親綱を折板構造の屋根に沿って張り渡す親綱張設用支柱取付具が記載されている。
特許文献１の親綱張設用支柱取付具は、アングル材にこのアングル材の長さ方向と直交する方向に親綱張設用支柱を突設し、このアングル材の両端部に折板構造屋根の重合突出条部を締め付け挟持する挟持部を備えた取付金具部を設け、この両端部の取付金具部の挟持部を折板構造屋根の隣接する重合突出条部にそれぞれ締め付け挟持してこの重合突出条部間に前記アングル材を架設した際、前記親綱張設用支柱が折板構造屋根に対して立設状態となるようにしている。
For example, Patent Literature 1 describes a strut attachment for laying a master rope that stretches a master rope to which a lifeline is hooked along a roof having a folded plate structure.
The strut attachment tool for the master rope tension in Patent Document 1 has a strut for the master rope tension projecting on the angle member in a direction perpendicular to the length direction of the angle member, and a folded plate structure at both ends of the angle member. A mounting bracket portion having clamping portions for clamping and sandwiching the overlapping protruding strip portion of the roof is provided, and the clamping portions of the mounting bracket portions at both ends are respectively clamped and clamped on the adjacent overlapping protruding strip portion of the folded plate structure roof. When the angle member is installed between the overlapping protruding strips, the strut for straddle tension is set up in a standing state with respect to the folded plate structure roof.
しかし、特許文献１の親綱張設用支柱取付具は、一体構造のため重量があり搬送が容易ではなく、作業者に負担がかかる。
特に、支柱を取り付けるまでは親綱が存在しない状態であり、屋根への取り付け作業に危険が伴う。
また、屋根構造の種類に応じてそれぞれの取付穴を形成した取り付けジグを用意しなければならず、汎用性に欠けるという問題点がある。
However, the strut attachment for laying the parent rope of Patent Document 1 is heavy because of the integral structure, and is not easily transported, which places a burden on the operator.
In particular, there is no parent rope until the support is attached, and there is a danger in the work of attaching to the roof.
Moreover, it is necessary to prepare mounting jigs having respective mounting holes in accordance with the type of roof structure, and there is a problem that the versatility is lacking.
そこで、本発明は、このような現状に鑑み、簡易な作業によって折板構造や波板構造屋根に取り付けすることができ、且つ簡易構造であって容易に実現可能となる親綱張設具を提供することを目的とする。 Therefore, in view of such a current situation, the present invention provides a master rope tensioning device that can be attached to a folded plate structure or a corrugated sheet roof by a simple operation and that can be easily realized with a simple structure.

さらに、渦巻きの内終端（渦巻きの最も内側になる端部）１９ｂはフリーの状態であり、渦巻きの巻軸方向Ｙ（渦巻き面とは直角方向であり、親綱張設用支柱１６に固定した場合は水平方向となる）に突出するように形成させている。
一例として、図４（ｂ）に示すように、渦巻きの外終端１９ａの延出方向に対して５°のねじれ角で渦巻き状に形成され、フリー状態の内終端１９ｂを巻軸方向Ｙ方向に突出させている。なお、この５°のねじれ角は、使用の態様によって適宜変更することができる。
このような渦巻き状に形成することによって、親綱２１の途中部を親綱固定金具１９に固定する場合は、親綱２１を下から上へ持ち上げて親綱張設用支柱１６の側面に当接させるようにして、渦巻き状の親綱固定金具１９の中に挿入して引っ掛ければよく、また、一旦、親綱固定金具１９の渦巻き中に引っ掛けた親綱２１は、渦巻き状の内終端が巻軸方向に突出して形成されているので、容易には外れにくい構造となっている。
The number, position, and the like of the master rope fixing bracket 19 are not specified and can be appropriately selected. However, in the embodiment, in order to hook the master rope from any direction on the upper part of the master rope tensioning column 16, 90 ° Four are attached for each rotation.
Further, the master rope fixing bracket 19 is formed in a spiral shape, and its outer end 19a is fixed to the parent rope tension strut 16 so as to be perpendicular to the surface on which the spiral is formed (the spiral surface). ing.
Further, the inner end (the innermost end of the spiral) 19b of the spiral is in a free state, and the spiral axis direction Y (perpendicular to the spiral surface and fixed to the strut 16 for stretching the main rope) In this case, it is formed so as to protrude in the horizontal direction.
As an example, as shown in FIG. 4 (b), it is formed in a spiral shape with a twist angle of 5 ° with respect to the extending direction of the outer end 19a of the spiral, and the inner end 19b in the free state is moved in the winding direction Y direction. It is protruding. Note that this 5 ° twist angle can be appropriately changed depending on the mode of use.
When the middle part of the master rope 21 is fixed to the master rope fixing bracket 19 by forming it in such a spiral shape, the master rope 21 is lifted from the bottom to the upper side to the side face of the parent rope tensioning column 16. The main rope 21 that is hooked in the spiral of the parent rope fixing bracket 19 is inserted into the spiral parent rope fixing bracket 19 so as to be in contact with the spiral rope. Is formed so as to protrude in the direction of the winding axis, and thus has a structure that is not easily detached.
＜屋根への固定＞
次に、親綱張設具の屋根への固定方法について具体的に説明する。
図５（ａ）は、親綱張設具を波板屋根に設置した状態を示す断面図であり、（ｂ）はその内の一部の右側面を拡大した右側面図である。
図示するように、親綱張設具１０の屋根２０への固定は、固定金具を用いて行う。
固定金具としては、例えば、屋根２０を、屋根２０の下方に位置する梁材２２にフック２３ａを固定するフックボルト２３を用いることができる。
フックボルト２３の上方の雄ネジ部２３ｂを、親綱張設具の固定梁材１３及び可動梁材１４の貫通孔（図示せず）に挿通して、ナットで固定する。
これによって、屋根２０の山部に沿って形成された突条２０ａに、親綱張設具１０を固定することができる。
屋根へは、屋根２０の突条２０ａと、側部梁材３および可動梁材４とが直交するように設置を行う。
