Description

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

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 cylindrical body 5 supporting the antenna pole is arranged in parallel,
Two small diameter tubes 6 were horizontally interposed between the protrusion 1 of the mounting plate 4 and the wall surface of the cylindrical body 5, and the joints were 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 antenna 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 welding points 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.

is required.

For this purpose, the antenna pole support in this case is formed by pressing a single metal plate.

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

FIG. 2 shows an outline of the installation of an 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 lead holes 14 for temporary fixing, and an antenna pole 11. A half-arc cylindrical support tube 16 to be supported, one end bent at an obtuse angle and connected to the mounting plate 15, the other end connected to the support tube 16, and a flange at the side end of the support tube 16. 17 and a connecting plate 18 that comes into contact with the supporting member, and in order to further increase the strength of this support, the upper and lower ends of the mounting plate 15 and the connecting plate 18 are shaped with bent pieces 19 facing inward (on the right side in FIG. 3). Intimidate.

Bent piece 1 at the corner joint between the mounting plate 15 and the connecting plate 18
9 particularly serves the function of increasing strength.

Further, the bent piece 19 is not provided at the upper end of the support tube 16 at a location where insertion of the antenna pole 11 would be hindered.

Further, in order to increase the strength, an embossment 20 is formed extending from the horizontal center of the connecting plate 18 to the connecting part with the mounting plate 15 inwardly (toward the right side in FIG. 3).

This embossment 20 disappears near the contact portion of the connecting plate 18 with the flange 17 of the support cylinder 16.

The antenna pole 11 inside the support tube 16 is attached to the tip of the connecting plate 18.
A bur ring 22 that is threadedly engaged with a set bolt 21 that supports the bur ring 22 and has a thread carved on its inner surface is provided to protrude inward.

This thread is carved by tapping after burring with a press.

If the plate thickness of this support is large, burring is not performed, and a hole may be drilled and then tapped.

The above shape is formed by pressing a single metal plate,
The flange 17 of the support tube 16 and the connecting plate 18 are fixed together by spot welding 23 which welds them in a dotted manner.

In addition to spot welding, this fixation can be done by gas welding, riveting, or by bending the bent piece 19 by press working to fix the flange 1.
There are methods such as holding 7.

In addition, this antenna pole support has a shape that is not bulky because the mounting plate 4 and the support tube 16 are connected on the same side of the connecting plate 18 (the right side in FIG. 3). Since it is bent at an obtuse angle, it is possible to stack the supports.

Next, this operation will be explained.

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

Next, the antenna pole 11 is fitted into the support tube 16 and the set bolt 21 is screwed in to support the antenna pole 11 in the support tube 16.

As mentioned above, this idea consists of a flat mounting plate that is attached to a building wall, a cylindrical support tube that supports the antenna pole, one end of which is bent at an obtuse angle to the mounting plate, and the other end of which is connected to the mounting plate. A connecting plate that connects with the support tube and comes into contact with the side end flange of the support tube, and bent pieces formed inward at the upper and lower ends of the mounting plate and the connecting plate are formed by pressing a single metal plate. However, the antenna pole support is formed by fixing the support cylinder side end flange and the connecting plate by spot welding, and has a simple structure, easy processing, and low processing cost.

Next, welding was changed from gas welding, which welds the entire circumference of the joint, to spot welding, which welds in dots.In addition, we reduced the number of welding points as much as possible by constructing a single metal plate, and by spot welding. Because it sticks, it reduces damage caused by unevenness, cavities, etc. that occur during welding.

Furthermore, since the joint surface is only the contact portion between the flange of the support tube and the connecting plate, the number of joint surfaces can be reduced as much as possible to eliminate the cause of rust.

Since the mounting plate and the connecting plate are bent at an obtuse angle and have no bottom shape, the mounting of this support to the building wall requires screwing and nailing compared to the conventional vertical mounting. Operation 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.
