Description

[Detailed Description of the Invention] The present invention relates to a pad for attaching various types of pole fittings, such as a wiring arm or an overhead ground wire installation arm, to a power pole, a communication pole, or the like.

This pad is used in combination with a fastener. That is, as shown in FIG.
and a band-shaped fastener B are arranged in such a manner as to hold the pillar C, and with the pillar mounting hardware D (shown as a wiring arm in the figure) attached to the padding A, the hardware D is attached. ,
The hardware D is attached to the pillar C by connecting the three parts, the stopper A and the fastener B, with bolts E, E-nuts F, and F.

Conventionally, this pad A has a seat part A ₂ formed in a curved shape corresponding to the pillar C on the inside of a plate-like or other hardware attachment part A ₁ to which a pillar hardware D such as an arm arm is attached.
are integrally fixed, and the seat _A2 is attached to the column C in the manner described above in contact with the column C.

By the way, the pillar C is formed into a tapered pillar shape regardless of whether it is a power pole, a communication pole, or the like. Therefore, since the column diameter differs depending on the height position of the column C to which the hardware D is attached, the curvature of the seat A ₂ of the pad A is also varied in stages, so that the curvature of the seat A 2 is varied in stages and the diameter is uniform within a fixed column diameter range. It is customary to use different types of pins.

However, in the case where the pad is used for both column diameters within a certain range, when using the conventional pad A, the seat portion A ₂ is fixed to the hardware attachment portion A ₁ , so that it does not respond to changes in the column diameter. Since the seat A ₂ has no follow-up function, especially when the difference in curvature between the seat A ₂ and the column C is large, the contact between the two A ₂ and C becomes poor, and the load is applied to one or two points of the column C. This tends to cause local deformation and damage to the part, and the fixing state of the pad A, that is, the mounting state of the pillar fitting D becomes unstable.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a support for attaching a pillar hardware that exhibits a function of following changes in the diameter of a pillar and can ensure good contact with the pillar.

The feature of this invention is that it consists of a hardware mounting part to which the pillar mounting hardware is attached, and a pair of left and right seats that circumscribe the pillar, and the seats have a curved surface corresponding to the pillar. and is attached to the metal fitting attachment part so as to be rotatable around a vertical axis.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show the first embodiment of the present invention and the fourth embodiment of the present invention.
The second embodiment is shown in the figure and FIG. 5, and the third embodiment is shown in FIG.
Examples are shown respectively. In each of these first to third embodiments, the pillar mounting hardware is a wiring arm mounted horizontally on a pillar.

In each embodiment, reference numeral 1 designates a arm arm mounting portion formed in the shape of a frame having a U-shaped cross section, and 2, 2 designates a pair of seat portions. These seat parts 2, 2 have a contact surface 3 formed in a curved shape corresponding to the pillar P at the tip, and the base end parts can each be rotated around a vertical axis 4 with respect to the armrest attachment part 1. It is installed. To explain in more detail, the seat portion 2,
2, the upper and lower horizontal sides 2a, 2a, and the contact surface 3
The vertical side portion 2b has a substantially U-shaped cross section, and the cross-section arm mounting portion 1 is formed between the horizontal side portions 2a, 2a.
It is attached to the attachment part 1 as described above with the two parts being sandwiched. To form the seat portion 2, in the first embodiment, both horizontal sides 2a, 2a and the vertical side 2b are integrally formed by pressing a single plate. On the other hand, in the second embodiment, the seat portion 2 is formed by welding and fixing a separate vertical side portion 2b to the tips of the horizontal side portions 2a, 2a.
Further, in the case of the third embodiment, the horizontal side portions 2a, 2a are cut and raised from the vertical side portion 2b to form the seat portion 2 having the same form as the case of the second example.
Note that reference numeral 1a denotes arm arm mounting holes extending horizontally through both sides of the arm arm mounting portion 1 in the length direction.

This pad is attached to the arm 5 on the outer surface of the arm mount attachment part 1.
In this state, it is attached to the column P by connecting it to a band-shaped fastener (not shown) using bolts 6, 6 and nuts 7, 7, as in the conventional manner.

When using this pad, since the pair of seats 2, 2 is rotatable around the vertical axis 4 as described above, the column of the seat abutting surface 3 changes according to the diameter change of the tapered column P. It becomes possible to adjust the state of contact with P.

In other words, Fig. 3A and Fig. 5 show the case where the seat contact surface 3 and the column surface have the same curvature, and as shown in Fig. 3B, when the column diameter is smaller than this, both seats have the same curvature. By rotating the parts 2, 2 in the direction toward each other, and when the column diameter is large as shown in Fig.
Adjust the orientation of the seat parts 2, 2 so that the center line (column tightening center line) l of both seat parts 2, 2 is directed toward the pipe center o. In this way, by moving the seat contact surfaces 3, 3 to a position along the column surface as much as possible according to the change in the column diameter, on the small diameter side, the contact surfaces 3, 3 of both seats 2, 2 are placed at one point each on the column surface. , contact at a total of two points (previously one point), and on the large diameter side, the contact surfaces 3 and 3 contact the column surface at two points each, a total of four points (previously two points), and this A good contact condition can always be obtained within the range of column diameters used. This makes it possible to prevent local deformation and damage to the column surface due to local load concentration on the column surface, and
It is possible to improve the stability of the state in which the stopper is attached.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. 7 and 8. This fourth embodiment is intended to be attached to a cross arm that is attached parallel to a pillar P for installing an overhead ground wire.

Reference numeral 11 designates a arm arm mounting portion, which is made by welding and fixing a square pipe-shaped arm arm holder 11b to a frame 11a that is concave in plan and has a U-shaped cross section.
5 is inserted and bolted. 1
Reference numerals 2 and 12 denote a pair of seats, and these seats 12 and 12 have horizontal sides 12a and 12a, and a vertical side 12b having a contact surface 13, as in the case of the pad for the wiring arm. 12b, and the horizontal side part 12
a, 12a are attached to the frame 11a of the armrest attachment part 11 so as to be rotatable around the vertical axis 14. Reference numeral 16 denotes a band-shaped fastener, which includes a pair of semicircular band pieces 16.
a, 16b, and a bolt 16c and nut 16d that connect one ends of both band pieces 16a, 16b. The other ends of both band pieces 16a, 16b of this fastener 16 are fastened to the vertical shafts 14, 14 for mounting the seats, and the contact surfaces 13, 13 of the seats 12, 12 are in contact with the column surface. , both band pieces 16a, 16b are wrapped around the pillar P and the bolt 1 is tightened.
6c and the nut 16d, the fastener 16 and the stopper are attached to the pillar P.

The pad according to the fourth embodiment can also provide the same effects as those of the pads of the first to third embodiments.

By the way, in the above embodiment, only two examples of pole mounting hardware, a wiring arm and an overhead ground wire installation arm, were given, but the present invention is a pole mounting that can be attached to various types of poles using a pad and a fastener. It can be applied to all hardware. Further, the shape of the hardware attachment portion can be changed in various ways depending on the type, shape, etc. of the pillar mounting hardware.

As mentioned above, when using the pad of the present invention, it exhibits the ability to follow changes in the column diameter, ensuring good contact between the seat contact surface and the column surface, thereby preventing local deformation and damage to the column surface. It is possible to prevent this and also to stably attach the pillar mounting hardware to the pillar.
