摘要

Uniform board for forming the writing surface of luminous information installations and for accommodating image points that form autonomous construction units, mainly luminous points, for holding device composed of mutually known supports with brackets, characterized in that on the surface adapted to the end of each bracket are provided between the different supports at least two intermediate pieces of rows adapted with the backs to the surface, which are fixed to the end of the bracket fixed at the same height and run parallel to a certain distance, two pieces intermediate rows have on their backs respective fixation and retention appendages protruding towards the supports at the back as well as appendages supporting the front bracket protruding parallel to the roof, and because between the intermediate pieces of rows, arranged perpendicular to these, autonomously one the side of another and/or fixed to each other, there are provided column channels optionally provided also with retaining pillars and provided with a U-shaped cross-section, the ends of the wings of the U-shaped profile being bent inwards. In this manner, the column channels are fixed with their wing ends bent inward to the back of the row intermediate piece, and a releasable fastening element adapted to the bent wing end is provided and fixed to the retaining tab of the row intermediate piece. Into the column channel and/or to the folded end into the retaining pillar, and a bore or holes are formed in the base plate of the various column channels.
