As shown in FIGS. 1 and 2, the utility pole arm band 10 includes a band body 11, a pair of fastening tools 12, and a pair of fixing tools 13.

  In one example, the band body 11 is made of hot-rolled steel SS400 and has an elongated plate shape having a predetermined length. The band body 11 has a central portion 11 a bent into a curved surface with a predetermined curvature so that the band body 11 can be easily wound around the utility pole 1. The band body 11 has four through-holes (band-side attachment portions) 11c arranged at regular intervals along the length direction at both end portions 11b. Each through hole 11 c is square and penetrates the band body 11 in the thickness direction at the center position in the width direction of the band body 11.

  Each fastener 12 is made of hot-rolled steel SS400, for example, and is detachably attached to both end portions 11b of the band main body 11, respectively. Each fastener 12 has a back surface portion 12 a disposed on the outer surface side of the band main body 11 and a protruding portion 12 b disposed on the inner surface side of the band main body 11. The back surface portion 12 a has a rectangular plate shape and has a width that is slightly wider than the width of the band body 11. The back surface portion 12a has a plurality (two in one example) of mounting holes (clamping side mounting portions) 12c. Each mounting hole 12c has a square shape having the same size as each through-hole 11c, and penetrates the back surface portion 12a in the thickness direction at the center position in the width direction of the back surface portion 12a.

  Each protrusion 12b has an end surface 12d on the side in contact with the cylindrical surface of the utility pole 1 formed in a concave shape. The end face 12d has the same curvature as the curvature of the smallest diameter among the utility poles 1 having different diameters that can be attached. Each protrusion 12b has a bolt hole 12e. The bolt holes 12e are provided so as to penetrate in the width direction of the band main body 11 on the side close to the end 11b of the band main body 11 when each fastener 12 is attached to the band main body 11.

  Each fastener 12 has the mounting holes 12c of the back surface portion 12a arranged in the length direction of the band main body 11, and the end portions 11b of the band main body 11 are changed to arbitrary through holes 11c by arbitrary mounting holes 12c. It can be attached. Each fastener 12 is fixed to the through-hole 11c with a bolt 2 and a nut 3 penetrating the arbitrary attachment hole 12c on the arbitrary through-hole 11c. Each fastener 12 can change the attachment position to the band body 11 by changing the attachment hole 12c and the through hole 11c fixed by the bolt 2 and the nut 3.

  Each fixing tool 13 has a U-shaped bolt 21 and an arm fastening bracket 22. The U-shaped bolt 21 is formed with male screws at both parallel end portions, and the central portion perpendicular to both end portions has a width slightly larger than the width of the back surface portion 12a of each fastener 12. The U-shaped bolt 21 is inserted into the bolt hole 12e of each fastener 12 at the center, and is attached to each fastener 12 with both ends rotatable around the center.

  The arm fastening fitting 22 is made of hot-rolled steel SS400, for example, and has an elongated rectangular plate shape. The arm fastening bracket 22 has both side edges bent perpendicularly to one surface side and has a U-shaped cross section. The arm fastening bracket 22 has a pair of insertion holes (not shown) spaced at the same distance as the distance between both ends of the U-shaped bolt 21. The arm fastening bracket 22 has both side edges directed toward the center of the U-shaped bolt 21, and both ends of the U-shaped bolt 21 are inserted into the respective insertion holes, and nuts are attached to the male screws at both ends. 4 is screwed and attached to the U-shaped bolt 21.

  In the specific example shown in FIGS. 1 and 2, the size of each member is as follows. The band main body 11 has a length of 536 mm and a width of 40 mm. Each fastener 12 has a back surface portion 12a having a width of 70 mm. The U-shaped bolt 21 has a center axis distance of 91 mm at both ends. The arm fastening bracket 22 has a length of 127 mm and a width of 35 mm.

Next, the operation will be described.
The arm member 5 can be attached to the power pole arm band 10 so as to intersect the power pole 1 perpendicularly as follows. The arm member 5 is formed of, for example, a square pipe having a square or rectangular cross section, and is used as a brace such as a protruding arm for supporting an electric wire, a communication line, or the like via a lever.

  First, the band main body 11 is arranged with respect to the utility pole 1 so that the fixtures 13 are arranged on the left and right sides of the utility pole 1 at a height at which the arm member 5 is attached. Each fixing tool 13 is arranged on both the left and right sides of the utility pole 1, the arm member 5 is inserted between both ends of the U-shaped bolt 21, and the arm fastening fitting 22 is pressed against the arm member 5. The arm member 5 is disposed so that the electric pole is sandwiched between the central portion 11 a of the band main body 11, each fastener 12, and the arm member 5.

  At this time, each fastening tool 12 is moved along the length direction of the band main body 11 so that the end face 12 d is in contact with the utility pole 1. Each fastener 12 is attached to an arbitrary through hole 11c of the band main body 11 by an arbitrary attachment hole 12c at a position where the arm member 5 can be easily attached. In this state, the nuts 4 at both ends of the U-shaped bolt 21 are tightened, and the arm member 5 is pressed against the utility pole 1 by the arm fastening fittings 22 on both the left and right sides of the utility pole 1. Thus, the utility pole 1 can be fastened by the band main body 11, the respective fasteners 12, and the arm member 5, and the arm member 5 can be fixed.

  The pole pole arm band 10 can adjust the position of each fastener 12 attached to the band body 11 by the plurality of through holes 11 c of the band body 11 and the plurality of attachment holes 12 c of each fastener 12. For this reason, compared with the case where the attachment hole 12c of each fastener 12 is one, fine adjustment is possible and the range which can be adjusted can be expanded. For this reason, it can respond to the electric pole of a wide range of diameters.

  In a specific example, the diameter of the power pole 1 that can be attached is 190 to 280 mm in the conventional power pole arm band 50 shown in FIG. 3, whereas it is 190 in the power pole arm band 10 shown in FIGS. 1 and 2. It is -330mm, and the range of the diameter of the electric pole 1 which can be attached is wide. The utility pole arm band 10 eliminates the need to prepare a plurality of types of utility pole arm bands for each diameter of the utility pole, thereby reducing costs such as material costs and manufacturing costs and facilitating product management. .

  Since the curvature of the end surface 12d formed in the concave shape is the same as the curvature of the minimum electric pole diameter of the electric pole 1 to be attached, each fastener 12 has at least two points of the end face 12d. Touch the cylindrical surface. On the other hand, in the conventional power pole arm band 50 shown in FIG. 3, each fastening tool 52 is formed of an L-shaped angle, so that each fastening tool 52 contacts the power pole 1 only at one point. For this reason, the conventional pole arm band 50 is somewhat unstable when attached to the utility pole 1. The utility pole arm band 10 is excellent in stability when attached to the utility pole 1 because each fastener 12 contacts the utility pole 1 at two points.
