The present invention provides a road signboard with high strength using hollow channels. The road signboard comprises: a signboard displaying various kinds of pieces of information; and a support frame installed to support the signboard. The support frame comprises: a plurality of double hollow channels; a plurality of T-shaped hollow channels; a plurality of horizontal pressurizing members; and a plurality of vertical pressurizing members. The double hollow channels are installed in parallel to support the signboard, with each having a reinforced wall formed on the interior surface of the hollow with a rectangular shape and a pair of ribs protruding from the reinforced wall in opposite directions. The T-shaped hollow channels are installed between the double hollow channels to be perpendicular to the double hollow channels to support the signboard and include each pipe part having a hollow section with a rectangular shape and a T-shaped reinforcing rib formed on the lower surface of the pipe part. The horizontal pressurizing members are installed between a pair of reinforcing ribs with double hollow channels and apply a force to each of the double hollow channels in a longitudinal direction. The vertical pressurizing members pass through the double hollow channels in a width direction and pass through interiors of the T-shaped hollow channels and apply a force to each of the T-shaped hollow panels in a longitudinal direction to couple the double hollow channels with the T-shape hollow channels. |
