The profile (1) has an upright central portion (2) tapering towards its top, and two transverse portions (3). These transverse portions extend vertically between an anchoring profile (8) and a further plate profile (5). The upper ends of the lateral or transverse portions have attachments (7) for connection to the further profile. The lateral portions taper towards their bottoms and bear upon a web (6) of the further profile. The first plate profile has tongues (12) for engagement with the anchoring profile. The further profile is hat-shaped, and the lateral portions each include a folded stiffener (4). |
