A corner key (10) for connecting profiles (12, 14) together and a frame work assembly formed of such corner keys (10) and profiles (12, 14). Each profile (12, 14) has an anchoring channel (16, 18), a drainage and venting passage (20, 22) and a securing bore (24, 26). The corner key (10) has two adjacent inner corner faces (28, 30), two adjacent outer corner faces (32, 34), and opposite inner and outer side corner faces (36, 38). Tabs (40, 42) on the inner corner faces (28, 30) guide the coupling of the profiles (12, 14). Fasteners (48, 50) are inserted through the outer corner faces (32, 34) in corner key bores (44, 46) and in the bores (24, 26) of the profiles (12, 14). A drainage and venting passage (52) in the corner key (10) communicates with the drainage and venting passages (20, 22) of the profiles (12, 14).

L'invention concerne une clavette d'angle (10) permettant de relier des profils (12, 14) et un ensemble cadre constitué de ces clavettes d'angle (10) et de ces profils (12, 14). Chaque profil (12, 14) est doté d'un canal d'ancrage (16, 18), d'un passage de drainage et d'aération (20, 22) et d'un alésage de fixation (24, 26). La clavette d'angle (10) comporte deux faces d'angle internes adjacentes (28, 30), deux faces d'angle externes adjacentes (32, 34), et des faces d'angle latérales internes et externes opposées (36, 38). Des languettes (40, 42) situées sur les faces d'angle internes (28, 30) guident le couplage des profils (12, 14). Des fixations (48, 50) sont insérées à travers les faces d'angle externes (32, 34) dans les alésages de clavette d'angle (44, 46) et dans les alésages (24, 26) des profils (12, 14). Un passage (52) de drainage et d'aération placé dans la clavette d'angle (10) communique avec les passages de drainage et d'aération (20, 22) des profils (12, 14).
