Corner connectors for adhesive injection of the inner side of the frame, a frame structure with the corner connectors, as well as a method for the production of the corner connector and / or of the frame construction

摘要

Corner connector (1) made of extruded aluminum profile section (8), the legs (2, 3) to form a miter cut into two hollow profiles (15) is inserted, in which the cross-sectional geometry a central web (19) is provided, which in a special production method is produced by a groove (9), which in further recesses (10, 11, 12, 13) extends and in connection with the outer hollow profiles (15) chambers connected to one another (k9, k10, k11 and k12, k13) formed, via which an adhesive (22) which, by means of a in the area of the inner corner (6), below the filling chamber (k10) of the corner connector injection opening (16) provided in the hollow section (15) and is pressed into the region of the mitre joint above the groove (9), and on the surfaces in the area of the inner corner (6) and of the outer corner (7) of the corner connector is conducted.
