A bridge shaped road sign structure is provided to reinforce rigidity of horizontal beams by installing supports between clamping units, fastened to the horizontal beams, via pins. A bridge shaped road sign structure comprises posts, a pair of horizontal beams(102), supports and clamping units(300). The horizontal beams connect one post with the other post. Traffic sign boards are installed to the horizontal beams. The clamping unit includes clamps(310), flanges(320), and a fixing piece(330). Each clamp shapes into a semi-circle and holds the horizontal beam. The flanges are integrated with the ends of the clamps and fastened to each other by bolts(400) and nuts when the clamps are installed around the horizontal beam. The fixing piece is attached to the outer surface of the clamp. The support includes an insertion groove(220) and a fixing pin. The fixing piece of the clamp is inserted into the insertion groove of the support. The fixing pin passes through the insertion groove to fasten the fixing piece. |
