Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for supporting a waveguide used in a communication line using microwaves.

[0002]

2. Description of the Related Art A waveguide used for a communication line using microwaves is usually laid and fixed on a ladder-shaped laying ladder via a waveguide metal fitting. FIG. 6 shows a conventional waveguide metal fitting 50. Conventional waveguide bracket 5
0 is a waveguide support tool 51 having a donut-shaped hollow,
It is provided with two arc-shaped gripping metal fittings 52 and 53 that are connected to each other to hold the waveguide support tool 51 and can be opened and closed. This waveguide support metal fitting 50 is provided with a pillar fixing portion 54 bent in a substantially concave shape on one side of an arcuate holding metal fitting, and a male screw 61 and a nut 62 are provided on a substantially concave horizontal portion 55 of the pillar fixing portion 54.
A column through hole 56 for screwing the column 63 having the is provided. The pillar 63 is screwed into the pillar through hole 56,
The waveguide support metal fitting 50 holding the waveguide is laid and fixed to the ladder by the pillars 63.

However, recently, a cylindrical column is often used for a supporting structure of a communication line antenna. Also when laying a waveguide on this circular pipe pillar, a ladder-shaped laying ladder is attached to the circular pipe pillar, and the waveguide is laid and fixed to the laid ladder via the waveguide support metal fitting 50. . Circular tube columns are used for supporting structures of communication line antennas because of the design conditions of the installation site (reduction of wind pressure, restriction of installation area and position, reduction of construction period, design of surrounding environment, etc.). Because it is getting tougher. However, even when the waveguide is laid on the cylindrical column, there is a problem that the above-mentioned advantage cannot be fully utilized by the method of arranging the ladder-shaped laying ladder on the circular column.

[0004]

Therefore, when a waveguide is laid on a circular column, it is possible to directly fix the waveguide to the circular column without using a ladder-shaped laying ladder. Pipe support fittings have been proposed. By using this direct mounting type waveguide support metal fitting, the merit of the circular tube column can be fully utilized. On the other hand, the waveguide installed inside the station building attached to the supporting structure of the communication line antenna is naturally laid and fixed to the laying ladder through the waveguide support metal fitting. Therefore, at the installation site, when procuring such supporting brackets, how many direct-mounting type waveguide supporting brackets for circular pipe columns and how many waveguide supporting brackets for the laying ladder are required. However, not all the workers at the laying site are professional laying workers for the waveguides used for communication lines that use microwaves, so when procuring the There were often mistakes in type and number.

If an ordering mistake is simply caused by an error in the number of members, an additional order will be placed to procure each supporting metal fitting.
The laying site is not only a place with well-developed transportation means in the city, but most of the places have good prospects without radio interference in mountains that do not normally pass. It's a big problem. In addition, since the laying route may be changed at the laying site, it is usually necessary to prepare more supporting metal fittings than necessary. Of course, the large number of types of support fittings as described above complicates inventory management.

The present invention has solved the above-mentioned problems, and a single waveguide support fitting can be used as a waveguide support fitting for a circular pipe column.
Another object of the present invention is to provide a waveguide metal support that can be used as a waveguide metal support for a laid ladder.
