Description

[Detailed Description of the Invention] This invention relates to an antenna pole support comprising a support formed of a single metal plate and an arcuate band.

A conventional antenna pole support is shown in FIG.

That is, a mounting plate 4 has a rectangular shape to be attached to a building wall, has a protrusion 1 extending vertically from the center and protruding forward, and has screw holes 2 for temporary fixing and holes 3 for nails drilled on both sides.
The mounting plate 4 is arranged in parallel with the cylindrical body 5 that supports the pole.
Two small-diameter tube members 6 were horizontally interposed between the protruding portion 1 and the wall surface of the cylindrical body 5, and the joint portion was fixed by gas welding.

Numeral 7 is a nut welded to the outer peripheral surface of the cylindrical body 5, and 8 is a set bolt that is screwed into the nut 7 and supports the pole within the cylindrical body 5.

By the way, this antenna pole support has a complicated structure, consisting of a mounting plate 4, a cylindrical body 5, and a tube material 6, and has many components, and is laborious and expensive to process.

Moreover, since each part is fixed by gas welding, it is difficult to maintain uniform quality because the parallelism between the mounting plate 4 and the cylinder body 5 cannot be maintained due to the effects of welding distortion and the like.

The antenna pole support is exposed to wind and rain, but the support broke at the welded part, which was weak in terms of strength.

Furthermore, when this support was attached to a building wall, the pipe material 6 was fixed vertically to the mounting plate 4, making it difficult to screw and nail.

Therefore, in view of the above-mentioned circumstances, this invention attempts to make the antenna pole support satisfy the following conditions.

That is, (1) The structure is simple, easy to process, and can be provided at low cost.

(2) Reduce the number of welded parts to achieve uniform quality and maintain strength.

(3) Water droplets can enter between the joint surfaces, causing rust and reducing strength, so the number of joint surfaces should be reduced as much as possible.

(4) Since the installation of this support to the building wall is often done on dangerous scaffolding such as on the roof, the structure must be easy to install.

(5) It is easy to attach the pole to the support.

is required.

For this purpose, the present invention is an antenna pole support consisting of a support formed by pressing a single metal plate and a semicircular arc-shaped band.

Hereinafter, this invention will be described in detail based on embodiments shown in the accompanying drawings.

FIG. 2 shows an installation outline of one embodiment of the antenna pole support of this invention.

An antenna pole support 12 that supports an antenna pole 11 having an antenna 10 attached to the top thereof is attached in a cantilevered manner to a pillar 9 on a building wall.

This antenna pole support 12 is shown in FIGS. 3 and 4, and includes a flat mounting plate 15 that is attached to a building wall and has screw holes 13 and nail holes 14 for temporary fixing, and a mounting plate 15 for attaching the pole 11 to the building wall. Semi-circular arc-shaped vertical recess 1 connected to the outer circumferential surface
6 and a band 1 supporting the pole 11 on both sides of this recess 16.
A pole support plate 20 having a screw hole 18 for attaching the pole 7 and a fitting hole 19 are bent at an obtuse angle and arranged in a row.

In order to support the pole 11 on the support plate 20 with the two bands 17, two sets of screw holes 18 and fitting holes 19 are bored upward and downward, and the distance between the screw holes 18 and the fitting holes 19 is equal to that of the pole 1.
1, and the screw hole 18 may be carved in the burring part or a nut may be provided separately, and the fitting hole 19 is set slightly larger than the tip of the band 17.

In order to reinforce this support 12, bent pieces 21 are formed on the upper and lower edges of the mounting plate 15 and the pole support plate 20.
5 and the pole support plate 20 from the connection part between the pole support plate 20 and the pole support plate 20
An embossment 22 is provided over the center of the frame.

The above shape is formed by pressing a single metal plate.

On the other hand, the band 17 is made of sheet metal, bent into a semicircular arc shape, and has a locking groove 23 that is larger than the plate thickness of the pole support 12 opened downward at one end, and the other end is connected to the locking groove 23. The bolt is bent outward in a right angle direction, and a bolt insertion hole 25 is bored in the bent portion 24.

26 is a mounting bolt. Next, this operation will be explained.

First, attach this antenna pole support 12 to the pillar 9 on the wall of the building.
When attempting to attach it to a post, etc., insert the temporary fixing screw screwed into the post 9 into the screw hole 13 of the mounting plate 15, and then drive a nail through the nail hole 14 to fix the support 12 to the post 9. do.

Next, attach the antenna pole 11 to the recess 1 of the pole support plate 20.
6, insert one end of the band 17 into the fitting hole 19 to engage the locking groove 23, and then insert the bolt 26 through the insertion hole 25 of the band and into the screw hole 18 of the pole support plate 20. The bolts 26 are screwed together and tightened until the lower part of the bolt 26 contacts the bent portion 24 of the band 17.

Then, the locking groove 23 at one end of the band 17 is connected to the pole support plate 20.
It firmly locks into the insertion hole 19 of.

On the other hand, in order to remove the antenna pole 11 from the support 12, remove the bolt 26 and attach the band 17 to the support 12.
You can separate it from.

As mentioned above, this device has a flat mounting plate to be attached to a building wall, a vertical recess for supporting a pole, screw holes and insertion holes facing both sides of this recess, and is bent with the mounting plate. A continuous pole support plate is formed by pressing a single metal plate, and a locking groove is formed at one end of a roughly semicircular arc-shaped band provided separately from this, and an insertion hole is drilled at the other end. The antenna pole support has a locking groove that is locked into the insertion hole of the pole support plate, and a bolt is inserted through the insertion hole and screwed into the screw hole of the pole support plate, and the structure is simple and processing is easy. It is easy and the processing cost is low.

Secondly, since it is constructed from a single metal plate and there are no welded parts, damage caused by unevenness, cavities, etc. caused by welding is reduced.

Furthermore, since the joint surface is only the contact portion between the locking groove of the band and the insertion hole of the support, the number of joint surfaces can be reduced as much as possible to eliminate the cause of rust.

Furthermore, the pole is attached to the support by locking the locking groove at one end of the band and tightening only the other end with a bolt, which is easier than using U-bolts or the like.

To attach this support to the building wall, the mounting plate and the connecting plate are bent at an obtuse angle and formed, so it requires screwing and nailing compared to the conventional vertical installation. has become extremely easy.

Furthermore, since this support is easy to process, it is possible to produce supports with high uniformity, and the number of defective products is small, making it suitable for mass production.

Moreover, since the structure is simple and not bulky, packaging and transportation are less troublesome and less packaging materials are required.
