Description

  The present invention relates to an armrest device for a traffic sign board.

  In general, the traffic sign plate is suspended from a brace protruding from a utility pole by fastening means, and the brace generally uses a cylindrical body for dealing with snow accumulation. The brace is mounted with the base portion inserted between the upper and lower holding pieces fastened to the electric pole with the band pieces, and the holding pieces protruding in the radial direction of the electric pole using bolts and nuts.

  In the conventional example, the brace is arranged in a state of projecting in the radial direction of the electric pole, so the brace in the mounted pole state is vertically connected to a cable, an electric wire, a support line, a signal lamp, etc. stretched on the electric pole. If the cable or the like is in the proximity of the lower part of the armrest, it will be difficult to suspend the traffic sign board from the armrest. .

  The present invention was devised to provide a brace armor device capable of suspending a traffic sign board irrespective of the presence of a support line or the like stretched in the radial direction of the utility pole.

  A semicircular engagement groove is horizontally provided on the front plate of the main body of the pole metal fitting clamped to the electric pole surface by a band piece, and is formed by a central piece and a lower piece that is continuous with the upper and lower sides of the central piece The sandwiching piece is superposed on the front plate via a cylindrical brace engaged with the engaging groove, and the front half piece is joined to the semicircular central piece engaged with the brace of the sandwiching piece. A pair of through-bolts passed through the arm through the face plate, and a tightening bolt through the front plate through the upper and lower pieces, respectively, and nuts screwed into the tips of the bolts protruding from the clamping pieces It is a configuration.

  According to the present invention, it is possible to perform the column mounting work by using the through bolts assembled to the pole fittings attached to the utility pole side so that the arm metal is temporarily fixed to the utility pole side and tightened with the clamping pieces. It is possible to provide a device that can efficiently perform the column work.

  In addition, even in the columnar state, since the armor is assembled to the columnar bracket using a pair of through-bolts, the arm can be reliably maintained in the original cantilevered state without tilting, Since gold is arranged in a tangential direction with respect to the utility pole, a traffic sign board can be hung without interfering with cables arranged in the radial direction of the utility pole.

  The drawings show an embodiment of the armrest device for a traffic sign board according to the present invention, FIG. 1 is a front view, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. 3 is a side view of FIG. 4 is a cross-sectional view taken along line 3a-a of FIG.

  The armrest device for a traffic sign board according to the present invention is configured such that a mounting bracket 1 is fastened to a power pole D, a clamping piece 4 is fastened to a main body 2 of the mounting bracket 1 using a tightening bolt 3, and the clamping device 4 is clamped. A base portion of an arm metal 5 is interposed between the piece 4 and the main body 2 and sandwiched.

  The mounting bracket 1 is assembled so that it can be rotated by a pivot made up of a bolt 7 and a nut 8 screwed to a pair of upper and lower band pieces 6, 6 on both sides of the rear end side of the bracket body 2. The metal fitting body 2 constituting the pillar metal fitting 1 is formed by engaging and welding the sub-frame 2B having a cross-sectional lateral groove shape on both sides inside the main frame 2A having a substantially cross-sectional lateral groove shape, Engagement grooves 10 are provided in the center in the vertical direction of the front plate 9 constituted by the main frame 2A, and first through holes are formed on the left and right sides of the bent piece 9a of the front plate 9 constituting the engagement grooves 10. 11 and 11, and second through holes 12 and 12 are provided on both sides of the flat upper and lower pieces 9 b and 9 b ′ of the front plate 9 through the first through hole 11, respectively.

  Further, the post fitting 1 is configured such that the fastening bolts 3 are inserted into the pair of left and right second through holes 12 and 12 provided on the front plate 9 and the lower pieces 9b and 9b 'from the rear side of the front plate 9, respectively. In addition, a pair of left and right first through holes 11, 11 provided in the central piece 9 a are combined with the through bolts 13 penetrating from the rear side of the front plate 9, and provided on both sides on the rear end side of the metal fitting body 2. A pair of corresponding band pieces 6 and 6 wound around the electric pole D so that the anti-tilt plate 14 is brought into contact with the surface of the electric pole D are attached to the electric pole D by the tightening bolts 15 and the tightening nuts 16 screwed thereto. Since it is fastened and fastened to the surface of the electric pole D with two pairs of upper and lower band pieces 6, 6, it has a structure with load resistance.

  A pair of through holes 17 and 17 corresponding to the first through holes 11 and 11 provided in the front plate 9 are provided in the engagement groove 10 provided in the front plate 9 of the pole fitting 1 fastened to the utility pole D. The base of the arm metal 5 is engaged with the through hole 17 so as to pass through the through bolt 13 assembled on the front plate 9 side, and the clamping piece 4 is overlapped from the outside of the base of the arm metal 5. Then, this is tightened to the post fitting 1 using the tightening bolt 3 via the arm metal base 5 to form the apparatus of the embodiment.

  The sandwiching piece 4 is made of a steel plate as in the case of the post fitting 1, and the upper and lower sides of the central piece 4 a having a semicircular cross section that forms the engaging groove 18 symmetrical to the engaging groove 10 provided in the front plate 9. Both sides are formed by connecting a lower plate 4b and 4b 'on the front plate 9, a flat plate facing the lower plates 9b and 9b', and the central piece 4a on the first plate on the front plate 9 side. A first through hole 19 is provided at a position matching the through hole 11, and a second through hole 20 is provided at the upper and lower pieces 4b and 4b 'at a position matching the second through hole 12 on the front plate 9 side. It is configured.

  The clamping piece 4 is assembled with a through bolt 13 projecting from the side of the post fitting 1 through the through hole 17 of the arm base at the first through hole 19 and the post fitting 1 at the second through hole 20. The attached fastening bolts 3 are passed through the base metal fittings 1 through the arm metal base 5 so as to pass through each of them (during this superposition operation, the arm metal 5 is a pair of through-bolts arranged along the axis thereof. 13 and 13 and is temporarily fixed to the mounting bracket 1 so that the working efficiency can be increased.) A fastening nut 21 is attached to the tip of the through bolt 13 protruding from the first through hole 19. Further, as described above, the embodiment device is obtained by screwing and tightening the tightening nut 22 to the tip of the tightening bolt 3 protruding from the second through hole 20.

  In the figure, 30 is a traffic signal lamp, 31 is a brace support device for the lamp 30, and 31 'is a support line for the support device, which is interfered with the support line 31' by using the device of the present invention. The traffic sign board 33 can be mounted.
