The embodiments described below are merely examples of the present invention, and the present invention is not limited to the following embodiments, and can be appropriately modified within the scope of the technical idea of the present invention.

＜実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１の構成＞
本発明に係る実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１は、図１に示すように鉄道の線路(図示せず。)の両脇に立設された支柱３,３間に渡され、水平方向に延びる鋼管ビーム４の外周面に公知のバンド金具２によって取り付けられるもので、図２～図５等に示すようにベース体１１と、ベース体１１の表面側に設けられた金具本体１２と、一対の接合補強用金具１３，１３とを溶接等によって接合して構成される。尚、図１において、５は掛止金具、６は命綱等のワイヤーである。 <Structure of Fall Prevention Device Mounting Bracket/Scaffolding Bracket 1 for Steel Pipe Beam of Embodiment>
As shown in FIG. 1, a steel pipe beam fall prevention device mounting bracket and scaffolding bracket 1 according to an embodiment of the present invention is installed between pillars 3, 3 erected on both sides of a railroad track (not shown), as shown in FIG. It is attached by a known band metal fitting 2 to the outer peripheral surface of a steel pipe beam 4 that extends in the horizontal direction. As shown in FIGS. The metal fitting main body 12 and a pair of metal fittings 13, 13 for joint reinforcement are joined by welding or the like. In FIG. 1, 5 is a latch, and 6 is a wire such as a lifeline.

（ベース体１１）
ベース体１１は、後述する図８や図９等に示すように表面側をバンド金具２が通って鋼管ビーム４に押し付けられ、裏面側が鋼管ビーム４の外周面に当接するもので、表面側におけるバンド金具２の通路にはバンド金具２の後述するスリット孔２２ｂ，２２ｂそれぞれに嵌る凸部１１ａ，１１ａが設けられている。 (Base body 11)
As shown in FIGS. 8 and 9, which will be described later, the front side of the base body 11 is pressed against the steel pipe beam 4 through the band fitting 2, and the back side of the base body 11 is in contact with the outer peripheral surface of the steel pipe beam 4. The passage of the band metal fitting 2 is provided with protrusions 11a, 11a that fit into slit holes 22b, 22b of the band metal fitting 2, which will be described later.

ここで、ベース体１１の表面側で設けられる凸部１１ａ，１１ａは、ベース体１１裏面側から押し出すことにより形成されている。そのため、凸部１１ａ，１１ａの裏側（反対側）には、図４(ｂ)に示すように押出し成形により凹部１１ｂ，１１ｂが形成され、凹部１１ｂ，１１ｂ縁部が鋼管ビーム４外周面に接触した際には、滑り止めとなる。 Here, the convex portions 11a, 11a provided on the surface side of the base body 11 are formed by extruding from the back side of the base body 11. As shown in FIG. Therefore, recesses 11b, 11b are formed by extrusion molding on the back side (opposite side) of the projections 11a, 11a as shown in FIG. When you do, it will be non-slip.

ここで、ベース体１１の表面側で設けられる凸部１１ａ，１１ａの間隔は、バンド金具２の複数のスリット孔２２ｂ，２２ｂ間の間隔と同じ間隔で設けられている。 Here, the interval between the projections 11a, 11a provided on the surface side of the base body 11 is the same interval as the interval between the plurality of slit holes 22b, 22b of the band fitting 2. As shown in FIG.

また、鋼管ビーム４には、複数の外径のものがあり、例えば、一般的には、外径が約２６７ｍｍ～３４０ｍｍ程度のものがほとんどである。そのため、ベース体１１の裏面側は、複数の外径の鋼管ビーム４の内、外径が最小の鋼管ビーム４の外径以下の内径Ｒ、ここでは、図３(ｂ)に示すように約２６７ｍｍ以下の約２６０ｍｍの内径で湾曲している。 The steel pipe beam 4 has a plurality of outer diameters, and most of them generally have an outer diameter of about 267 mm to 340 mm. Therefore, the back side of the base body 11 has an inner diameter R smaller than the outer diameter of the steel pipe beam 4 having the smallest outer diameter among the steel pipe beams 4 having a plurality of outer diameters. It is curved with an inner diameter of about 260 mm, which is less than or equal to 267 mm.

そのため、鋼管ビーム４の外径が変わった場合でも、常にベース体１１の上下端部が鋼管ビーム４表面に当接するため、鋼管ビーム４の外径の変更に対応して鋼管ビーム用墜落防止装置取付金具兼足場金具１のズレや回転を防止することができる。 Therefore, even if the outer diameter of the steel pipe beam 4 is changed, the upper and lower ends of the base body 11 are always in contact with the surface of the steel pipe beam 4, so that the fall prevention device for the steel pipe beam can be adapted to the change in the outer diameter of the steel pipe beam 4. Displacement and rotation of the mounting bracket/scaffolding bracket 1 can be prevented.

（金具本体１２）
金具本体１２は、安全帯等に使用される公知の掛止金具５（図１参照）が引っ掛けられ、かつ、作業員の足場として兼用できるように、例えばＤ１６ｍｍの異形棒鋼の両端を曲げることにより図３(ａ)に示すように幅Ｗが約２３０ｍｍのコ字形状に形成し、ベース体１１も含めた高さＨを約１２０ｍｍとしている。ここで、金具本体１２として異形棒鋼を使用した理由は、金具本体１２は掛止金具５の掛止だけでなく足場としても兼用するため、作業者が鋼管ビーム４の上で作業する際、靴が滑り難くするためである。 (Metal fitting main body 12)
The metal fitting body 12 is made by bending both ends of a deformed steel bar of D16 mm, for example, so that a known metal fitting 5 (see FIG. 1) used for a safety belt or the like can be hooked and can also be used as a scaffolding for workers. As shown in FIG. 3A, it is formed in a U shape with a width W of about 230 mm and a height H including the base body 11 of about 120 mm. Here, the reason why the deformed steel bar is used as the metal fitting main body 12 is that the metal fitting main body 12 is used not only for the latching of the latching fitting 5 but also as a scaffolding. is to make it difficult to slip.

（接合補強用金具１３，１３）
接合補強用金具１３，１３は、ベース体１１に金具本体１２を溶接等により接合するため一対で使用されるのもので、それぞれ、長手方向の中央にはバンド金具２を通すためのバンド金具通し用凹部１３ａを設ける一方、バンド金具通し用凹部１３ａの両側にはそれぞれメッキ液を抜くため等のメッキ液抜き孔１３ｂ，１３ｂを設けている。 (Joint reinforcing metal fittings 13, 13)
The joint reinforcement metal fittings 13, 13 are used as a pair for joining the metal fitting main body 12 to the base body 11 by welding or the like, and each has a band metal fitting thread through which the band metal fitting 2 is passed at the center in the longitudinal direction. On the other hand, on both sides of the band fitting recess 13a, plating solution drain holes 13b, 13b for draining the plating solution are provided.

（バンド金具２）
バンド金具２は、図６および図７(ａ)，(ｂ)に示すように公知のもので、自在バンドとも呼ばれており、例えば、特開２００６－２７１０２５号公報に開示されている。 (Band fitting 2)
As shown in FIGS. 6 and 7(a) and (b), the band metal fitting 2 is known and is also called a universal band, and is disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-271025.

つまり、バンド金具２は、例えば、図６および図７(ａ)，(ｂ)に示すように一端側には所定間隔を開けて複数（ここでは、例えば、３つとする。）の透孔２１ａ,２１ａが形成されていると共に、他端側にはそれぞれ緊締受部２１ｂ，２１ｂが形成された複数の一対の主バンド片２１，２１と、その複数の一対の主バンド片２１，２１の一方側に形成された複数の透孔２１ａ,２１ａの内のいずれか一の透孔２１ａと、両側にそれぞれ形成された（ここでは、例えば、４つとする。）の透孔２２ａ,２２ａの内のいずれか一の透孔２２ａとを一致させてそれぞれ接続ボルト２３，２３および接続ナット２４，２４によって一対の主バンド片２１，２１を連結する補助バンド片２２とを備え、一対の主バンド片２１，２１の他端側の緊締受部２１ａ，２１ａは、それらに形成されたボルト孔を介して緊締ボルト２５および緊締ナット２６により締付けて鋼管ビーム４に巻回できるように構成されている。 6 and 7(a) and (b), the band fitting 2 has a plurality of (here, for example, three) through-holes 21a at one end side at predetermined intervals. , 21a, and tightening receiving portions 21b, 21b are formed on the other end side, and one of the pair of main band pieces 21, 21. Any one of the plurality of through holes 21a, 21a formed on the side and through holes 22a, 22a formed on both sides (here, for example, four) of the through holes 22a, 22a an auxiliary band piece 22 that aligns with any one of the through holes 22a and connects the pair of main band pieces 21, 21 by connecting bolts 23, 23 and connecting nuts 24, 24, respectively; , 21 are configured to be wound around the steel pipe beam 4 by being tightened by tightening bolts 25 and tightening nuts 26 through bolt holes formed therein.

そして補助バンド片２２には、図６および図７(ａ)等に示すように所定間隔Ｌだけ離れた長穴形状のスリット孔２２ｂが２つ設けられている。 The auxiliary band piece 22 is provided with two elongated slit holes 22b separated by a predetermined interval L as shown in FIGS. 6 and 7(a).

＜本発明に係る実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１の取付状態＞
以上のように構成された実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１を、バンド金具２を使用して鋼管ビーム４に取付けると、図８～図１０に示すような状態になる。尚、図８では、ベース体１１表面側の凸部１１ａ，１１ａがバンド金具２の後述するスリット孔２２ｂ，２２ｂそれぞれに嵌る状態が隠れないようにするため、接合補強用金具１３，１３中央を切欠して図示している。 <Mounting State of Fall Prevention System Mounting Bracket/Scaffolding Metal Fitting 1 for Steel Pipe Beam According to Embodiment of the Present Invention>
When the steel pipe beam fall prevention device mounting bracket and scaffolding bracket 1 of the embodiment configured as described above is attached to the steel pipe beam 4 using the band bracket 2, the state shown in FIGS. 8 to 10 is obtained. . In FIG. 8, in order to prevent the projections 11a, 11a on the surface side of the base body 11 from being fitted into the slit holes 22b, 22b of the band metal fitting 2, which will be described later, the centers of the joint reinforcing metal fittings 13, 13 are not hidden. It is shown cut away.

ベース体１１の表面側に設けられた凸部１１ａ，１１ａの間隔は、バンド金具２の複数のスリット孔２２ｂ，２２ｂ間の間隔Ｌと同じ間隔で設けられているため、図８～図１０から明らかなように、ベース体１１の表面側に設けられた凸部１１ａ，１１ａがそれぞれバンド金具２の補助バンド片２２の所定間隔Ｌだけ離れた長穴形状のスリット孔２２ｂ，２２ｂの端部に嵌ることになる。 Since the distance between the projections 11a, 11a provided on the surface side of the base body 11 is the same as the distance L between the plurality of slit holes 22b, 22b of the band fitting 2, from FIGS. As is clear, the projections 11a, 11a provided on the surface side of the base body 11 are located at the end portions of the elongated slit holes 22b, 22b separated by a predetermined distance L in the auxiliary band piece 22 of the band fitting 2, respectively. it will fit.

そのため、鋼管ビーム用墜落防止装置取付金具兼足場金具１の金具本体１２にワイヤー６先端の掛止金具５（図１参照。）を引掛けたり、金具本体１２の上に作業員の足が乗って足場とした場合でも、ベース体１１の表面側に設けられた凸部１１ａ，１１ａが滑り止めとなるので、鋼管ビーム用墜落防止装置取付金具兼足場金具１のズレや回転を防止することができる。 For this reason, the metal fitting body 12 of the steel pipe beam fall prevention device mounting metal fitting and scaffolding metal fitting 1 can be hooked on the metal fitting 5 (see FIG. 1) at the tip of the wire 6, or the worker's foot can step on the metal fitting body 12. Even when it is used as a scaffolding, the projections 11a, 11a provided on the surface side of the base body 11 serve as anti-slip, so that it is possible to prevent the steel pipe beam fall prevention device mounting bracket and scaffolding metal fitting 1 from slipping and rotating. can.

また、ベース体１１の凸部１１ａ，１１ａがバンド金具２の補助バンド片２２のスリット孔２２ｂ，２２ｂの所定間隔Ｌと同じであり、図８～図１０に示すように２つの凸部１１ａ，１１ａがそれぞれ補助バンド片２２のスリット孔２２ｂ，２２ｂの端部に隙間なく嵌るので、鋼管ビーム用墜落防止装置取付金具兼足場金具１の上下方向を気にせず使用することが可能となり、作業性や鋼管ビーム用墜落防止装置取付金具兼足場金具１の使い勝手を向上させることができる。 Further, the projections 11a, 11a of the base body 11 are the same as the predetermined interval L between the slit holes 22b, 22b of the auxiliary band piece 22 of the band metal fitting 2, and as shown in FIGS. 11a are fitted into the end portions of the slit holes 22b, 22b of the auxiliary band piece 22 without gaps, so that the steel pipe beam fall prevention device mounting bracket and scaffolding bracket 1 can be used without worrying about the vertical direction, resulting in workability. It is possible to improve the usability of the fall prevention device mounting bracket and scaffolding bracket 1 for steel pipe beams.

また、ベース体１１の凸部１１ａ，１１ａの裏側には凹部１１ｂ，１１ｂが形成されているため、バンド金具２で実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１を鋼管ビーム４に押し付けて固定した際、ベース体１１裏側の凹部１１ｂ，１１ｂ縁部が鋼管ビーム４外周面に接触して滑り止めとり、この点でも鋼管ビーム用墜落防止装置取付金具兼足場金具１のズレや回転を防止することができる。 Further, since recessed portions 11b, 11b are formed on the back side of the protruding portions 11a, 11a of the base body 11, the band metal fitting 2 can be used to attach the steel pipe beam fall prevention device/scaffolding metal fitting 1 to the steel pipe beam 4. When pressed and fixed, the edges of the concave portions 11b and 11b on the back side of the base body 11 come into contact with the outer peripheral surface of the steel pipe beam 4 to prevent slipping. can be prevented.

＜本発明に係る実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１の主な効果＞
以上説明したように、本発明に係る実施形態の鋼管ビーム用墜落防止装置取付金具兼足場金具１は、表面側をバンド金具２が通って鋼管ビーム４に押し付けられ、裏面側が鋼管ビーム４の外周面に当接するベース体１１と、ベース体１１の表面側に設けられた金具本体１２とを有する。 <Main effects of the steel pipe beam fall prevention device mounting bracket and scaffolding bracket 1 of the embodiment according to the present invention>
As described above, the steel pipe beam fall prevention device mounting bracket and scaffolding bracket 1 according to the embodiment of the present invention is pressed against the steel pipe beam 4 through the band bracket 2 on the front side, and the outer circumference of the steel pipe beam 4 on the back side.
