<p>The panels 5a are fixed one on top of the other to a pole 8 by clamps 9 forming a collar surrounding the pole. Each panel 5a is mounted between brackets 18 of two clamps. The upper clamp 9 is screwed from the top to the upper panel 5a which contains for this purpose a nut trapped between its front wall and its end wall. The lower clamp is itself screwed from the bottom to the bottom of the lower panel. Plates 43, fixed to two panels 5a are interposed between these panels and each of the middle clamps. A bolt 56 clamps the bracket 18 of each middle clamp between the two plates 43, which makes it possible to fix the two panels 5a to one and the same middle clamp 9, although the panels are of the closed casing type. Use for simplifying the production of the elements constituting the assembly, reducing the rigidity necessary for the panels, eliminating the problems of relative positioning between panels. <IMAGE></p> |
