Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a method for manufacturing a support for supporting an antenna support on a roof or side wall. The present invention relates to a method of fixing a mounting plate formed to be mounted at a predetermined location such as a mounting plate and a mounting plate so as to face each other via an arm.

Conventionally, in the method for manufacturing the antenna support described above, since the support member that supports the antenna support has a cylindrical shape, at least the joint between the support member and the arm must be connected by welding. .

As a result, the workability in manufacturing the antenna support is poor, and the welded portions form abrasions on the surface of the product, impairing the quality of the product.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing an antenna support support that can improve workability and product quality in view of the drawbacks of the conventional manufacturing method described above.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawing, reference numeral 2 denotes a mounting plate that can be attached to a predetermined wall or pillar on which an antenna support (not shown) is to be attached. An insertion hole 2b for the arm is formed therethrough.

Note that 2a clearly shown in Fig. 6 is a plurality of mounting holes formed in the flange portions 2c on both sides of the mounting plate 2, and these are for fixing the mounting plate 2 to a wall or pillar with nails or the like. be.

Reference numeral 3 denotes a support member for the antenna support column formed into a cylindrical shape by combining the semi-cylindrical elements 3A and 3B.

In the above-mentioned one element 3A, arm insertion holes 3Ab, which will be described later, are formed through the vicinity of both ends in the longitudinal direction.

Further, in the other element 3B, a nut 5 having a flange 5a is attached near both ends in the longitudinal direction by means such as welding with the flange 5a inside, as shown in FIG. There is.

Incidentally, a bent portion 3Aa as shown in FIGS. 2 and 4 is provided at the abutting edge when the elements 3A and 3B are combined.

3Ba is formed respectively.

Next, reference numeral 1 denotes two arms, each of which has a diameter that allows it to be inserted into each of the insertion holes 3Ab of one of the elements 3A and the insertion hole 2b of the mounting plate 2, and a slight distance from the end. The flange 1a is formed by drawing, leaving a caulking allowance.

Now, the procedure for connecting the mounting plate 2, arm 1, and support member 3 prepared as described above will be explained.

First, with respect to the two arms 1, insert the insertion hole 2b of the mounting plate 2 from one side, insert the insertion hole 3Ab of one element 3A of the support member 3 from the other side, and connect the flanges 1a at both ends of the arm 1.
The mounting plate 2 and the element 3A are held in a facing state by inserting the mounting plate 2 and the element 3A to a position where they come into contact with each other.

After that, press the caulking portions at both ends of the arm 1 at once to attach the mounting plate 2 and the element 3A to the arm 1.
2 and 3, respectively.

As a result, the mounting plate 2 and the element 3A are coupled via the arm 1 in a facing state.

Next, in order to attach the remaining element 3B to the element 3A of the support member 3 previously attached to the arm 1, the bent portions 3Aa and 3Ba of the surface elements 3A and 3B are caulked together. Combine with .

As a result, the surface elements 3A and 3B are connected to the cylindrical support member 3.
Configure.

Next, when using the antenna support configured as described above, first insert an antenna support (not shown) into the support member 3.
and screw the bolt 8 for tightening the antenna support into the nut 5 of the support member 3.

In this case, the nut 5 shines and receives internal pressure when tightening the antenna support, but since the flange 5a of the nut 5 is in contact with the inner wall of the support member 3, the internal pressure causes the nut 5 to move away from the support member 3. It will not be peeled off.

Moreover, when the support member 3 must be lengthened according to the length of the antenna support, a plurality of supports in this example may be prepared and used in series.

In this case, the regulation piece 6 inserted into the lower part of the support member 3 to receive the antenna support is made removable from the support member 3, leaving only the lowest regulation piece 6 of the continuous support member 3. and use it.

Next, the effects of the present invention will be explained.

The present invention uses two semi-cylindrical elements 3A to form the support member 3 when manufacturing an antenna support support for attaching a cylindrical support member 3 for attaching the antenna support to the mounting plate 2 via the arm 1.

Bent parts 3Aa bent outward at both ends of 3B.

3Ba, one element 3A to which the mounting plate 2 is attached via the arm 1, and the other element 3B to which the bolt 8 and the mounting nut 5 are attached are each element 3A.

The bent portions 3Aa and 3Ba of 3B are butted together to form a cylindrical shape, and the bent portions 3 are butted against each other.
Both bent portions 3Aa are between Aa and 3Ba.

A method of manufacturing an antenna support support in which a caulking plate 7 for connecting 3Ba is inserted is provided.

As a result, the present invention can perform caulking and each element 3A, without using a press for assembly work even if a press is used for parts processing.
Assembly can be performed by simply attaching the caulking plate 1 to the bent portions 3Aa and 3Ba of 3B, thereby greatly simplifying the press machine and jig equipment necessary for manufacturing the antenna support support. , it is possible to extremely easily manufacture an antenna column support with a clean finish, high commercial value, and uniform quality without requiring any special technology or skill. The connecting structure of the portions 3Aa and 3Ba provides an elastic force in the radial direction of the support member 3, and has the effect of further improving the support effect of the antenna support while maintaining the function of preventing the bolt 8 from loosening.
