The composite structural shape comprises an internal structural component (2) which is essentially polygonal and tubular in cross-section, with two shorter internal (22) and external (21) faces and two longer faces (23, 24), with portions (29, 30) converging towards the shorter internal face (21) and an external structural component (1) the respective opposite faces of which (4, 22), are provided with pairs of hook-shaped projections (11, 12; 31, 32) forming C-shaped cavities (15, 14; 33, 34) inside which opposite ends of thermal insulation bars (19, 20) are housed, placed to form a connection between the internal structural component (2) and the external structural component (1). |
