The board can be used in the road infrastructure fordisplaying advertizing and information materials. It preserves thevisibility of the advertizing text for a longer section of theroad at increased resistance against wind loads. The boardconsists of a supporting column (1) fitted by its lower end (20)to a foundation (21), and fixed 3-dimensional body (3) is fixed inthe upper part (2) of column (1). The front of column (1) matcheswith the upper end of the 3-dimensional body (3) which is made ofthree sides (4, 5 & 6) in the form of a triangular prism open fromboth its bases and fitted to the supporting column (1) by a framestructure (7). The latter is made in the zone of each of the basesand forms at least two sections in the space between them. Each ofthe sections contains at least two stays which are parallel, andat least two stays fitted at an angle to the parallel ones. Thelower end (20) of column (1) is fixed to foundation (21) by meansof a supporting plate (22) and an anchor connection (25).3 claims, 2 figures/!
