In a set of profiles for forming complex profiles comprising two adjoining profiles having walls surrounding a main chamber, each profile (10, 20) has an inner wall (12, 22) with a faying face (13, 23) without protruding fragments whereas an angle (±, ²) between the faying face (13, 23) and an outer surface (15, 25) of a side wall (14, 24) of the first profile (10) and the second profile (20) is no greater than 90°, and after adjoining the first profile (10) and the second profile (20) with the faying faces (13, 23), in order to create a complex profile (30), the outer surfaces (15, 25) of the side walls (14, 24) of the first profile (10) and the second profile (20) are situated outside, and an angle (³) between them equals the sum of the angle (±) between the faying face (13) and the outer surface (15) of the side wall (14) of the first profile (10) and the angle (²) between the faying face (23) and the outer surface (25) of the side wall (24) of the second profile (20). Furthermore, each profile (10, 20) has at least one guiding element (7, 8) to guide an arm of a corner piece inserted into the main chamber and to reinforce connections with other profiles having axes situated at an angle to axes of profiles (10, 20). |
