Modular panel for surface covering e.g. ceiling, has frame including profile that has longitudinal parts with U-shaped and L-shaped transversal sections, where side of one section is contiguous to upper part of side of another section

摘要

The panel has a frame including a profile (1) composed of longitudinal parts having a U-shaped transversal section and an L-shaped transversal section. One of sides (30, 31) of the L-shaped transversal section is contiguous with an upper part of one of sides (20, 21) of the U-shaped transversal section, where the sides are disposed to form a step. Splines (40) clip the panel on a framework.
