図２は、第１、第２の載置部材４０、５０と屋根５との取り付け部分を勾配方向から見た平面図である。図１、２を用いて、安全器具１０の屋根への取り付け構造を説明する。 FIG. 2 is a plan view of the mounting portions of the first and second mounting members 40 and 50 and the roof 5 as viewed from the gradient direction. The structure for attaching the safety device 10 to the roof will be described with reference to FIGS. 1 and 2.

図１に示した屋根５は、瓦棒屋根であり、瓦棒６が所定距離間隔で勾配垂直方向に並んでいる。安全器具１０は、瓦棒６に取り付けられている雪止め金具を利用して屋根５に取り付ける。具体的には、第１の載置部材４０が、雪止め金具８０Ａ、８０Ｂに取り付けられ、第２の載置部材５０が、雪止め金具７０Ａ、７０Ｂに取り付けられている。雪止め金具７０Ａ、７０Ｂは、雪止め金具８０Ａ、８０Ｂの位置から勾配方向に沿って距離Ｌ１（図１参照）だけ離れた位置に設置されている。だたし、図１では、雪止め金具７０Ａ、７０Ｂ、８０Ａ、８０Ｂの図示を省略している。 The roof 5 shown in FIG. 1 is a tiled roof, and the tiled bars 6 are arranged in a vertical gradient direction at predetermined distance intervals. The safety device 10 is attached to the roof 5 by using the snow stopper attached to the tile bar 6. Specifically, the first mounting member 40 is attached to the snow stoppers 80A and 80B, and the second mounting member 50 is attached to the snow stoppers 70A and 70B. The snow stoppers 70A and 70B are installed at positions separated from the positions of the snow stoppers 80A and 80B by a distance L1 (see FIG. 1) along the gradient direction. However, in FIG. 1, the snow stoppers 70A, 70B, 80A, and 80B are not shown.

後述するように、第１の載置部材４０、第２の載置部材５０は、その長手方向に沿って複数の取付用穴を設けている。雪止め金具７０Ａ、７０Ｂと、雪止め金具８０Ａ、８０Ｂの頂部に設けられたボルト７５Ａ、７５Ｂ、ボルト８５Ａ，８５Ｂ（図２参照）を、第２の載置部材５０、第１の載置部材４０に設けられた取付用穴にそれぞれ通し、ナットで締め付けることによって、安全器具１０を屋根上に固定することができる。 As will be described later, the first mounting member 40 and the second mounting member 50 are provided with a plurality of mounting holes along the longitudinal direction thereof. The snow stoppers 70A and 70B and the bolts 75A and 75B and the bolts 85A and 85B (see FIG. 2) provided at the tops of the snow stoppers 80A and 80B are attached to the second mounting member 50 and the first mounting member. The safety device 10 can be fixed on the roof by passing through the mounting holes provided in 40 and tightening with nuts.

図３は、第２の載置部材５０を上から見た平面図である。 FIG. 3 is a plan view of the second mounting member 50 as viewed from above.

第２の載置部材５０の開口部側底面５０Ｍには、その中心ラインＣ１に沿って複数の取付用穴６０が形成されている。複数の取付用穴６０は、中央ラインＣ２を境にして対称的であり、互いに所定間隔離れて配置されている。ここでは、中央ラインＣ１に位置する穴６１、中央ラインＣ２に最も近い一対の穴６４Ａ、６４Ｂが形成され、また、その外側には中心ラインＣ１に沿って横長の穴６２Ａ、６２Ｂが形成され、さらに外側にある穴６０Ａ、６０Ｂが形成されている。第１の設置部材４０も、同様の取付用穴６０が同じ位置に形成されている。 A plurality of mounting holes 60 are formed along the center line C1 on the bottom surface 50M on the opening side of the second mounting member 50. The plurality of mounting holes 60 are symmetrical with respect to the central line C2 and are arranged at predetermined intervals from each other. Here, a hole 61 located at the center line C1 and a pair of holes 64A and 64B closest to the center line C2 are formed, and horizontally long holes 62A and 62B are formed on the outside thereof along the center line C1. Further, holes 60A and 60B on the outer side are formed. In the first installation member 40, a similar mounting hole 60 is formed at the same position.

取付用穴６２Ａ、６２Ｂは、隣り合う瓦棒６の距離間隔Ｄ１に応じた間隔で第２の載置部材５０に形成されている。したがって、作業者は、第１の載置部材４０、第２の載置部材５０に設けられた取付用穴６２Ａ、６２Ｂを使って、第１および第２の載置部材４０、５０を屋根に取り付けることができる。 The mounting holes 62A and 62B are formed in the second mounting member 50 at intervals corresponding to the distance interval D1 between the adjacent tile rods 6. Therefore, the operator uses the mounting holes 62A and 62B provided in the first mounting member 40 and the second mounting member 50 to attach the first and second mounting members 40 and 50 to the roof. Can be attached.

一方、雪止め金具７０Ａ、７０Ｂと雪止め金具８０Ａ、８０Ｂは、本来、屋根５の勾配垂直方向に沿って配置する棒状部材（図示せず）を瓦屋根５に取り付けるための金具であり、その設置個所は適宜定められ、その配置位置は固定されない。本実施形態では、あらかじめ屋根５に取り付けられていた多数の雪止め金具のうち雪止め金具７０Ａ、７０Ｂ、８０Ａ、８０Ｂを用いて安全器具１０を固定している。 On the other hand, the snow stoppers 70A and 70B and the snow stoppers 80A and 80B are originally metal fittings for attaching a rod-shaped member (not shown) arranged along the vertical direction of the slope of the roof 5 to the tiled roof 5. The installation location is determined as appropriate, and the location is not fixed. In the present embodiment, the safety device 10 is fixed by using the snow stoppers 70A, 70B, 80A, and 80B among the many snow stoppers previously attached to the roof 5.

図４は、連結部材３０を伸縮させたときの第２の載置部材５０の位置を示した図である。連結部材３０の長さは、雪止め金具７０Ａ、７０Ｂ、８０Ａ、８０Ｂの勾配方向に沿った配置間隔Ｌ１に合わせて調整される。この調整によって、第２の載置部材５０の取付用穴６２Ａ、６２Ｂの位置を、雪止め金具７０Ａ、７０Ｂの位置に合わせることができる。 FIG. 4 is a diagram showing the position of the second mounting member 50 when the connecting member 30 is expanded and contracted. The length of the connecting member 30 is adjusted according to the arrangement interval L1 along the gradient direction of the snow stoppers 70A, 70B, 80A, 80B. By this adjustment, the positions of the mounting holes 62A and 62B of the second mounting member 50 can be aligned with the positions of the snow stoppers 70A and 70B.

以上、瓦棒タイプの屋根５に安全器具１０を取り付ける説明を行ったが、安全器具１０は、他の種類の屋根に対しても取り付けることが可能である。以下では、波型スレート屋根、折板屋根への安全器具１０の取り付けについて説明する。 Although the safety device 10 has been described above for the tile bar type roof 5, the safety device 10 can also be attached to other types of roofs. Hereinafter, the attachment of the safety device 10 to the corrugated slate roof and the folded plate roof will be described.

図５は、波型スレート屋根の斜視図である。波型スレート屋根１５０は、その断面が波状に形成された屋根であり、所定のピッチで規則的に山と谷が繰り返される。ここでのスレート屋根１５０は、既存の波形スレート屋根の上に新設屋根をカバーしたものであり、直接固定方法あるいは間接固定方法などに従い、新設屋根がボルト（屋根の取り付け金具）１５２によって既存の波形スレート屋根に取り付けられている。 FIG. 5 is a perspective view of a corrugated slate roof. The corrugated slate roof 150 is a roof whose cross section is formed in a wavy shape, and peaks and valleys are regularly repeated at a predetermined pitch. The slate roof 150 here covers the new roof on the existing corrugated slate roof, and the new roof is corrugated by the bolt (roof mounting bracket) 152 according to the direct fixing method or the indirect fixing method. It is attached to the slate roof.

ボルト１５２はナット１５３とともに波の頂部から突出し、ここでは、その勾配垂直方向に沿った配置間隔Ｄ２が、スレート屋根１５０のピッチ２つおきの間隔に定められ、瓦棒６の配置間隔Ｄ１よりも大きい。また、ボルト１５２の勾配方向に沿った配置間隔Ｌ２も、瓦棒６の配置間隔Ｌ１より大きい。 The bolt 152 protrudes from the top of the wave together with the nut 153, and here, the arrangement interval D2 along the vertical direction of the gradient is set at an interval of every two pitches of the slate roof 150, and is larger than the arrangement interval D1 of the tile bar 6. big. Further, the arrangement interval L2 along the gradient direction of the bolt 152 is also larger than the arrangement interval L1 of the tile bar 6.

作業者は、このボルト１５２の配置間隔Ｄ２、Ｌ２に従って安全器具１０を設置する。図３に示すように、ボルト１５２の配置間隔Ｄ２は、取付用穴６２Ａ、６２Ｂがカバーしている。したがって、作業は、取付用穴６２Ａ、６２Ｂの端部付近でボルト１５２を取付用穴６２Ａ，６２Ｂに通し、ナット１５３を締め付けることによって固定する。また、連結部材２０の長さを、配置間隔Ｌ２に合うように調整し、連結部材３０の親綱支柱２０、第２の載置部材５０に対する取り付け角度も合わせて調整する。 The operator installs the safety device 10 according to the arrangement intervals D2 and L2 of the bolts 152. As shown in FIG. 3, the arrangement interval D2 of the bolts 152 is covered by the mounting holes 62A and 62B. Therefore, the work is fixed by passing the bolt 152 through the mounting holes 62A and 62B near the ends of the mounting holes 62A and 62B and tightening the nut 153. Further, the length of the connecting member 20 is adjusted so as to match the arrangement interval L2, and the mounting angle of the connecting member 30 with respect to the main rope support 20 and the second mounting member 50 is also adjusted.

図６は、折板屋根の斜視図である。折板屋根２５０は、山と谷が交互に繰り返されるタイトフレームに折板を上から取り付けた構造の屋根であり、重ね型などの折板屋根では、山の頂部にボルト２５２がナット２５３とともに突出している。 FIG. 6 is a perspective view of a folded plate roof. The folded plate roof 250 is a roof having a structure in which folded plates are attached from above to a tight frame in which peaks and valleys are alternately repeated. ing.

ボルト２５２は山ごとに設置されているため、隣り合うボルト２５２の距離間隔Ｄ’は比較的短く、取り付け対象のボルト２５２を選択することができる。ここでは、取付用穴６０Ａ、６０Ｂ（図３参照）に応じた距離間隔Ｄ３をもつボルト２５２が選ばれる。一方、勾配方向に関しても、比較的に短い距離間隔でボルト２５２が配置され、選択可能である。ここでは、連結部材２０を最も伸ばしたときの距離間隔Ｌ３に応じた配置間隔のボルト２５２を使って安全器具１０を固定する。 Since the bolts 252 are installed in each mountain, the distance interval D'of the adjacent bolts 252 is relatively short, and the bolt 252 to be attached can be selected. Here, a bolt 252 having a distance interval D3 corresponding to the mounting holes 60A and 60B (see FIG. 3) is selected. On the other hand, with respect to the gradient direction, the bolts 252 are arranged at relatively short distance intervals and can be selected. Here, the safety device 10 is fixed by using bolts 252 having an arrangement interval corresponding to the distance interval L3 when the connecting member 20 is most extended.

これは、第１、第２の載置部材４０、５０において、使用する取付用穴の距離間隔が大きい、すなわち使用する取付用穴が中央ラインＣ２から離れるほど、連結部材２０を伸ばして第１、第２の載置部材４０、５０の距離間隔を広げるためである。 This is because, in the first and second mounting members 40 and 50, the connecting member 20 is extended so that the distance between the mounting holes used is large, that is, the mounting holes used are separated from the central line C2. This is to increase the distance between the second mounting members 40 and 50.

屋根５、１５０、２５０に安定して固定することを考慮すれば、第１、第２の載置部材４０、５０の両端付近の取付用穴を使って固定するのが好ましい。折板屋根２５０のように使用するボルトを比較的自由に選択できる場合、第１、第２の載置部材４０、５０の距離間隔をより大きくすることで、構造上親綱支柱２０を強固に支持することが可能となる。 Considering stable fixing to the roofs 5, 150 and 250, it is preferable to fix them using the mounting holes near both ends of the first and second mounting members 40 and 50. When the bolts to be used can be selected relatively freely like the folded plate roof 250, the main rope support 20 is structurally strengthened by increasing the distance between the first and second mounting members 40 and 50. It will be possible to support.

このように本実施形態における安全器具１０は、第１の載置部材４０、第２の載置部材５０を備え、親綱支柱２０を第１の載置部材４０の中央部分に搭載し、親綱支柱２０と第２の載置部材５０の中央部分との間を伸縮可能な連結部材３０で連結した構成となっている。そして、第１および第２の載置部材４０、５０には、それぞれ、屋根の種類に応じた複数の取付用穴６０が設けられ、複数の取付用穴６０は、様々な屋根の取り付け器具（雪止め金具を含む）の設置間隔に合わせて形成されている。 As described above, the safety device 10 in the present embodiment includes the first mounting member 40 and the second mounting member 50, and the main rope support 20 is mounted on the central portion of the first mounting member 40 to form a parent. The structure is such that the rope support 20 and the central portion of the second mounting member 50 are connected by a stretchable connecting member 30. The first and second mounting members 40 and 50 are each provided with a plurality of mounting holes 60 according to the type of roof, and the plurality of mounting holes 60 are used for various roof mounting fixtures ( It is formed according to the installation interval of (including snow stoppers).

このような安全器具１０の構成により、様々な種類の屋根（平屋根を含む）にも安全器具１０を設置することが可能であり、極めて汎用性が高く、上述した屋根以外に対しても適用することが可能である。また、親綱支柱２０を第１の載置部材４０の中央部分に載せ、第２の載置部材５０の中央部分に取り付けた連結部材３０を親綱支柱２０に対し所定角度を持たせて連結させることにより、その支持構造のバランスがよく、安定している。さらに、補強部材３６、３７によって親綱支柱２０の支持が強固になっている。 With such a configuration of the safety device 10, it is possible to install the safety device 10 on various types of roofs (including flat roofs), which is extremely versatile and can be applied to roofs other than those described above. It is possible to do. Further, the main rope support 20 is placed on the central portion of the first mounting member 40, and the connecting member 30 attached to the central portion of the second mounting member 50 is connected to the main rope support 20 at a predetermined angle. By making it, the support structure is well-balanced and stable. Further, the reinforcing members 36 and 37 strengthen the support of the main rope support column 20.
