PURPOSE: A support frame for a sign board is provided to prevent the inflow of moisture through a gap and the damage due to the perforation of a screw hole. CONSTITUTION: A support frame comprises an upper panel(10) a lower panel(20), and a coupling unit. The upper panel and the lower panel form a step recess and a hooking recess at the front side of the exterior side. The hooking recess is connected to the step recess. A front panel forms an inserting projection and a holding protrusion. The inserting projection is inserted and combined with the step recess. The holding protrusion is projected from the end of the inserting projection to the inner surface and is hung on the holding protrusion. A coupling block is formed into a semi-circular column shape. The coupling unit combines the coupling block with a bracket which fixes a sign board by a fastening screw. |
