Abstract
A support frame is intended to support the decorative sheet product and is formed of a plurality of longitudinal elements and horizontal elements, which are in turn formed of a plurality of base portions and main bodies. The base portions are provided with a protrusion and a recess opposite in location to the protrusion, and two slots opposite in location to each other. The base portions are joined together by the mortise-tenon joints to form the longitudinal elements. The main bodies are provided with two protruded blocks opposite in location to each other and are arranged in alignment such that the protruded blocks are received in the slots of the base portions of the longitudinal elements, and that the main bodies form the horizontal elements perpendicular to the longitudinal elements.
