Novelty: method for the connection of thermally-insulating aluminium profiles and connection angle thereof is disclosed. Constitution: a connection angle composed of the sections (13,14) bearing through holes (18,19) into which there are positioned spiral pressure springs (20,21) entering along with the metal cylindrical elements (22,23,24,25)-with which the two ends of said springs are in contact- the internal chambers (12,7) of the thermally-insulating profiles (2,1), said chambers being formed by the polyamides (10,11,5,6) and the sections (8,9,3,4). Being in compressed condition, the metal cylindrical elements (22,23) allow the free entry of the connection angle into the internal chamber (1). Then, with the assistance of the aforementioned springs, the cylindrical elements expand and secure into the holes (26) and (27), respectively. The stable connection of the thermally-insulating profiles (1,2) is achieved upon tightening of the screw (16). |
