Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a washer for attaching arms, arms, etc. to concrete utility poles or steel pipe poles.

The object of the present invention is to open a cut window in the center of the plane of a pole mounting seat plate made of a single rectangular plate into which an arm or an arm and a flexible band for tightening are inserted, and fold the lower end into a U-shape to connect it to a utility pole. This is a contact surface, and the arm arm installation is completed by simply inserting the arm arm and tightening the band with two square plates of the same shape facing each other, and even with a single load, it is possible to handle a single load without attaching an arm tie. The present invention provides a column washer with no arm ties that can withstand high temperatures, and is easy to install, and even when a single load is applied to the arm and there is a possibility that the arm will tilt, the arm can be fixed without using an arm tie. To provide an economical no-arm tie-equipped column washer in which the inclination does not exceed a certain limit, which is ideal especially when supporting a heavy object such as a transformer with a support arm.

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

FIGS. 1A and 1B show that a substantially rectangular arm-piece insertion hole 5 is made in the center of a pillar mounting seat plate 1 made of a single rectangular plate, and this arm-piece insertion hole 5 is Above both inner edges, inclined surfaces 6, 6' are formed so as to approach each other and become narrower, and the upper inner edges 9, 9' following these inclined surfaces become the abutting surfaces of the upper surface of the armrest, and the upper inner edges 9, 9' A U-shaped recess 15 into which the adjustment plate/temporary fastening plate 7 fits is provided on the inner side of the adjustment plate/temporary fastening plate 7. The dimensions are such that they fit correctly into the recesses 11a and 11a'.

The lower end of the seat plate 1 for mounting the pillar is folded to one side in a U-shape, and the tip is 2, and the folded curved surface is 3. A cut window 18 for insertion of the flexible band 8 is opened upward from the folded curved surface 3 at the center of the lower end of the pillar mounting washer plate 1,
The inner edges 19, 19' of this cutout 18 are dimensioned to properly fit into the serrations 11, 11' of the flexible band 8. When the flexible band is inserted diagonally into the cutout 18 and flattened, both inner edges 19, 19' and the serrated notches 11, 11' fit together.

FIG. 2A and FIG. 2B show a flexible band, in which one end of a band-shaped plate 8 has a protrusion 10 in the shape of a saw blade,
Reinforcing side plates are formed by cutting off concave portions 11 and 11' one by one, leaving 10', to form a hook part.The other end of the strip plate 8 is bent, a bolt hole 16 is made in the center, and the other ends are squeezed outward on both sides. 18a and 18b are provided.

3A and 3B show an adjustment plate/temporary fastening plate, in which both ends of the adjusting plate/temporary fastening plate 7, which is made of one band-shaped plate, are connected to the saw blade-shaped notches of the flexible band 8. Exactly the same convex portions 10a, 10a' and concave portions 11a, 1
1a' and bolt holes 12, 13,
Line up 13′ and open. The holes 13, 13' are for tightening the armrests by bolting if necessary.

Next, the installation order of the present invention will be explained.

(1) When installing a pole with a washer attached to an armrest on the ground, first bend the lower ends 2 of the two seat plates 1 into a U-shape as shown in Figures 4A and 4B. Attach armrests a to the cut window 5, facing each other inward in the direction of
Insert the adjustment plate/temporary plate 7 into the U-shaped recess 15 at the upper end of the cut window 5 along the cross arm surface, and insert the adjustment plate/temporary plate 7 into both inner edges 15', 15'' of the U-shaped recess 15. Fit the notch in the retaining plate 7. Tie this to the middle of the cross arm a with a passing rope. Pull the flexible band 8 onto the utility pole b as well, place the arm arm a against the pole surface, and tighten the saw of the flexible band 8. Insert the blade-like tips into the holes 18 of the seat plate 1 and adjust their occlusal positions, and also pull or spread the tips of the square plate 1 of the washer inward using the adjustment plate/temporary plate 7 to set it at an appropriate position. The work is completed when both are fitted and the bolt c of the flexible band 8 is tightened.

(2) When attaching a pole mounting seat plate to a desired position on a utility pole in advance and inserting a cross arm later.In a complex location with a large number of overhead wires on the pole or near high-voltage lines, long and heavy Used when operating a large arm is considered dangerous. That is, as shown in FIGS. 4A, 4B, 5A, and 5B, first insert each of the two flexible bands 8 into the cutout 18 of the seat plate 1 made of two rectangular plates,
The inner edges 19, 19' of the cut window 18 are fitted into the recesses 11, 11' of the sawtooth cutout of the band 8 at arbitrary positions. When band 8 is tied loosely with bolt c, two seat plates 1 and two flexible bands 8
are connected in series with bolt c. Separately, one adjustment plate/temporary retaining plate 7 is pulled up onto the column. The two seat plates 1, which are connected in series to form the ends, are wrapped around a utility pole d, and then the adjustment plate/temporary plate 7 is inserted into the notch 4 of the two seat plates 1.
Fit it on the top side of the When the bolt hole part of the flexible band 8 is pulled by hand, the seat plate 1 will stop on the telephone pole. By tightening the nut c' of the bolt c, the seat plate 1 is firmly attached to the telephone pole. Then, the center surface of the temporary holding plate 7 comes into contact with the outer circumferential surface of the utility pole b, so that the arm insertion hole 5
is completely outside the column surface and does not interfere with the insertion of cross arm a. As shown in Figure 5b, insert the armband a into the armlet insertion hole 5 from one side, and when it is in the correct position, loosen the nut c' of the bolt c of the adjustable band 8 and remove the adjustment plate/temporary fastening plate 7. Pull it out and immediately insert it into the notch 15 on the front of the arm arm a, pull the ends of the two seat plates 1 and 1 together, or make appropriate adjustments such as spreading them apart, and then move the adjustment plate/temporary plate 7 to both sides of the notch 15. Fit the inner edges 15' and 15'' and tighten the nut c' of the bolt c. Thus, Fig. 4A
Then, as shown in Figure 4B, the mounting of the arms is completed.

Figures 6A and 6B show other examples of seat plates when angles are used as armrests, and are for inserting square arms as explained in Figures 1A and 1B above. Instead of the hole 5, an L-shaped armrest insertion hole 5 is made, and the upper edge of the bottom side 5a of this L-shaped armrest insertion hole 5 is a U-shaped recess into which the adjustment plate/temporary plate 7 is inserted. 15
are provided, and the inner edges 15', 1 of this U-shaped recess 15 are
5″ is a serrated notch 11a of the adjustment plate/temporary fixing plate 7,
The dimensions shall be such that it fits correctly with 11a'. Other details are the same as those described with respect to FIGS. 1A and 1B.

As described above, in the present invention, a cut window is formed in the center of the plane of one square plate into which the arm or cross arm and a flexible band for tightening are inserted, and the lower end is folded back into a U shape to form a contact surface with the telephone pole, so the shape is the same. Attachment of the arm to the utility pole can be completed by simply placing the two square plates facing each other, inserting the arm and tightening the band. Therefore, the installation method is easy, and even when there is a concern that the arm may tilt when a single load is applied to the arm, the arm's tilt does not exceed a certain limit without using an arm tie. It is also suitable for supporting heavy objects such as transformers with armrests, and the washer is easy to manufacture, installation work is easy, and it is economical.
