Abstract

<P>PROBLEM TO BE SOLVED: To provide a mounting apparatus for cross arms for poles which apparatus is provided with inclination preventing effect and thus from which the stable state of installation of a cross arm can be expected. <P>SOLUTION: Each mounting base frame 3 is constructed of first and second pieces 4 and 8 disposed in the direction in which they cross each other and connected to each other. This mounting base frame is placed at both the ends of a band 1 placed along the circumference of a pole D by connecting them with a connecting bolt 6 and a connecting nut 7 at each first piece 4. A pair of threaded rod portions 10A, 10A of U-shaped assembling bolts 10 are inserted into the second pieces 8 of the individual mounting base frames 3. Pressing pieces 12 are assembled to the threaded rod portions with the threaded rod portions 10A penetrating therein. A cross arm 11 is placed between the threaded rod portions 10A, 10A with tightening nuts 12 screwed onto the tips of the threaded rod portions 10A protruded from the pressing pieces 12. This cross arm is pressure welded to the circumferential side face of the pole D. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a mounting device for a brace that is attached to a utility pole for use as a support material for an equipment pole.

  A base material is attached with bolts and nuts to both ends of a band piece along the peripheral side of the utility pole, and the screw part is passed through a pair of screw parts of a U-shaped bolt penetrated through each base material. And having a structure in which a fastening nut that presses a brace that is penetrated through the screw rod to the peripheral side of the utility pole via the material is screwed to the tip of the screw rod protruding from the corresponding material. There is (for example, Patent Document 1).

Japanese Utility Model Publication No. 45-16350

  In the conventional structure, a pair of upper and lower arc edges are provided on the base material, and the arc edges are made to coincide with the arc on the power pole peripheral side to obtain a stable mounting state of the arm bracket. It is practically impossible to match the arc edge on the material side with the arc on the peripheral side of the utility pole, because of the relationship with machining accuracy, etc. The installation state cannot be obtained.

  The present invention was devised to eliminate the drawbacks of the prior art and to provide a mounting device for a utility pole arm that can be expected to have a tilt-inhibiting effect.

  A mounting base frame composed of first and second pieces arranged in a crossing direction at each end of the band along the circumferential side of the utility pole, and connecting bolts and connecting nuts in the first piece. Are connected to each other and attached to the pair of threaded portions of the U-shaped mounting bolts that are penetrated by the second piece of each mounting base frame, and the pressing pieces are assembled by penetrating the threaded portions. A clamp nut is screwed onto the tip of the screw portion protruding from the pressing piece, and a brace interposed between the screw portions is pressed against the peripheral side surface of the power pole.

Effect

  According to the present invention, the mounting base frames arranged at both ends of the band form a so-called triangular shape composed of a first and a second, and the free end side of each piece is disposed along the vertical direction of the utility pole. Because of this relationship, it is possible to obtain a mounting device for a utility pole arm that can be expected to have a reliable tilt prevention effect and a stable arm mounting state.

  BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a partially cut-out plan view, FIG. 2 is a front view, and FIG. 3 is a partially exploded cross-sectional view showing the relationship of each part. .

  In the figure, 1 is a band arranged along the peripheral side of the utility pole opening, and the band 1 (made of steel) has adjustment holes 2, 2, and 2 arranged at both ends to correspond to the utility pole D diameter. The through holes 4 provided in the first piece 5 of the mounting base frame 3 superimposed on the inner side of the band 1 are made to coincide with the appropriate ones of the adjustment holes 2, 2, 2, and the through holes 4 are aligned with these holes. The connection bolt 6 is penetrated from the side, and a connection nut 7 is screwed and fastened to a bolt 6 tip protruding from the through hole 4, and the mounting base frame 3 is assembled on both sides of the band 1.

  The mounting base frame 3 is composed of a vertically long bent body in which the first piece 5 and the second piece 8 are connected in a crossing direction, and the free ends 5 ′ and 8 ′ of the pieces 5 and 8 are the electric poles D. It is used so as to abut on the circumferential side. The second hole 4 is provided in the central portion of the first piece 5 in the longitudinal direction (vertical direction), and the second hole 4 is positioned at the central portion. The piece 8 is configured by providing a pair of upper and lower penetrating items 9 and 9.

  Then, as described above, the first piece 5 of the attachment base frame 3 is attached to the band 1 using the bolt 6, and the screw piece 10 </ b> A is passed through the through holes 9 and 9 in the second piece 8. A U-shaped bolt 10 is assembled, and the outer side of the arm metal 11 interposed between the pair of screw parts 10A and 10A protruding from the second piece 8 of the bolt 10 (the electric pole D side is the inner side). A clamping piece 13 provided with a pressing piece 12 assembled so as to penetrate the screwing part 10A and screwed to the tip of the screwing part 10A protruding from the pressing piece 12. The brace 11 is pressed and attached to the peripheral surface of the utility pole D through the pressing piece 12.

  The U-shaped bolt 10 is constructed by providing the screwed portions 10A and 10A relative to each other on both sides of the central hooked portion 10B, and the distal ends of the screwed portions 10A and 10A are bent in the same direction and at the same angle. A portion 10A ′ is provided so that the screwed portions 10A and 10A can be arranged in parallel between the bolts 10 and 10 in accordance with the inclination angle of the second piece 8 of the mounting base frame 3.
