In addition, a conical sleeve 9 is provided at the bottom of each mounting base 12, 13.
An annular groove 15 is recessed concentrically with the annular groove 15, and both the inner and outer walls of the annular groove 15 converge upward.

The raised end of the lower plate 16 fits into the annular groove 15, and the outside of this end has the same taper as the annular groove 15.

A recess 17 having a hole communicating with the conical sleeve 9 is provided at the center of the lower part of the lower plate 16 as shown in the figure, and a connecting rod 19 extends through the hole in the direction of the center line of the column 2.
A head 18 of the head 18 is accommodated in the recess 17.

The connecting rod 19 passes through the lower plate 16, the conical sleeve 9 of the upper plate, the strut 2, and the partition plate 20 of the lid-like member, and tightens the above parts together by a screw and nut 21 attached to the upper end. .

And the mounting base 12, 130 protrusion 11 and annular groove 1
5 are fitted into the upper plate 8 and the lower plate 16 facing each other as shown in the figure to couple the two.

That is, when the nut 21 is tightened, the connecting rod 19 tightens the upper end of the lower plate 16 into the annular groove 15, and the protrusion 11 fits into the annular groove 10 of the upper plate 8, so that:
The radiating member 3 or crossbeam 4 is fixed to the column 2.
