It is like that. When the position of the retaining member 22 is close to the top of the support 61, as is conventionally known, for example, as in Patent Document 1, the top of the support 61 and the retaining member 22 are connected to each other. The stop member 22 may be prevented from slipping down.

The operation of installing the parabolic antenna 2 using the above configuration will be described.
First, the anti-skid tool 19 is attached to the lower part of the column 61 where the parabolic antenna 2 is to be attached (lower part of the attachment position of the lower fastening fixture 18).
Next, the parabolic antenna 2 to which the connecting structure 7, the abutting member 50 in the lower fastening fixture 18 and the mating member 30 in the upper fastening fixture 17 are joined is lifted by an arbitrary means such as using a crane, and the parabola in the support 61. The antenna 2 is moved to the planned mounting position. In this case, the abutting member 50 in the lower fastening fixture 18 is positioned so as to rest on the upper surface of the anti-skid 19 attached to the column 61 first, and the inner peripheral surface 51a of the abutting member 50 and the upper fastening fixture. 17 so that the inner peripheral surface 31a of the mating member 30 faces the surface 61a of the column 61 on the parabolic antenna side.

Next, the retaining member 22 is attached to the surface 61 b of the support 61 on the side opposite to the parabolic antenna, and is firmly tightened against the mating member 30 in the upper tightening fixture 17.
Further, the tightening detent member 37 is positioned above the mating member 30 and on the surface 61a side of the column 61 on the parabolic antenna side, and temporarily tightened against the retaining member 22 (with the outer peripheral surface of the column 61). So that the gap G can be seen between them).
On the other hand, in the lower fastening fixture 18, the fastening member 44 is opposed to the surface 61 b of the support 61 on the side opposite to the parabolic antenna and temporarily tightened against the abutting member 50 (gap G between the support 61 and the outer peripheral surface). To the extent that you can see).
In this tightening operation, if the worker is instructed to reduce the gap G, the worker tightens the tightening tool 62 hard and, in many cases, the retaining member 22 and the tightening detent Tightening is performed until the member 37 is in pressure contact with the peripheral surface of the support column 61, thereby making it difficult to adjust the azimuth angle of the next stage. Therefore, it is preferable that there is a gap G so that it can be visually observed.
In this state (see FIGS. 1A and 2B), the load of the parabolic antenna 2 is applied in the direction of gravity (the direction of the arrow 65). Thereby, the load of the parabolic antenna 2 is transmitted through the connection structure 7, and forces in the directions of the arrows 66 and 67 are applied to the upper fastening fixture 17 and the lower fastening fixture 18, respectively. Is added to the retaining member 22 and the abutting member 50. As a result, the inner peripheral surface 23a of the retaining member 22 and the column surface 61b, the inner peripheral surface 51a of the abutting member 50, and the surface 61a of the column 61 are brought into close contact with each other. Fixed even when tightened

Next, the azimuth angle of the parabolic antenna 2 is adjusted. The azimuth adjustment work is performed by rotating the parabolic antenna 2 or the arm 8 of the connection structure 7 in the circumferential direction (in the direction of the arrow 70 in FIG. 2B) as usual.
In this state (see FIGS. 1A and 2B), in the upper fastening fixture 17, there is a gap G between the fastening detent member 37 and the support post 61, and the lower fastening. In the fixture 18, there is a gap G between the fastening member 44 and the column 61. Therefore, the rotation operation in the circumferential direction can be performed smoothly.
Furthermore, since the retaining member 22 and the mating member 30 in the upper fastening fixture 17 are slidably in contact with the outer peripheral surface of the column 61, even if there is a gust during this azimuth adjustment operation, The antenna resists the lifting force in the direction of arrow 68 due to strong winds, so that the relational position between the support column and the parabolic antenna can be firmly maintained, and the operator can safely perform the antenna mounting work.
When the azimuth angle adjustment is completed, the tightening work in the upper tightening fixture 17 and the lower tightening fixture 18 is completed. That is, the tightening detent member 37 in the upper tightening fixture 17 is firmly tightened against the retaining member 22, and both are crimped to the outer periphery of the column 61 to prevent the retaining member 22 from rotating. Further, the fastening member 44 in the lower fastening fixture 18 is firmly fastened to the abutting member 50 to integrate the three members.
As described above, when the upper tightening fixture 17 and the lower tightening fixture 18 are completely tightened, the tightening detent member 37 and the retaining member 22 of the upper tightening fixture 17 are not attached to the column 61. To be fixed. Further, the fastening member 44 and the abutting member 50 in the lower fastening fixture 18 are fixed to the support 61. Therefore, the relational position between the support column and the parabolic antenna can be maintained firmly, and the parabolic antenna 2 is stably installed in a state adjusted to a predetermined elevation angle and azimuth angle.
