PL436065A1 - Thermal break of an aluminium joinery profile - Google Patents

Abstract

The subject of the invention is a thermal break of an aluminum profile of construction joinery, in particular a door leaf profile, a door frame profile, a window frame profile, a window frame profile or a profile of filling openings used especially in residential construction and industrial facilities. The thermal break (1) of the aluminum joinery profile connects the aluminum external section (2) with the aluminum internal section (3). The space between the aluminum outer section (2), the aluminum inner section (3) and the thermal breaks creates a thermal chamber (4). The thermal break (1) consists of two connected walls (5 and 6). There are two partitions (7a) between the walls (5 and 6). The spaces between the walls (5 and 6) and the partitions (7a) form the chambers (8). In the middle of the outer wall (5) there is a recess (9) that merges into a hole (10). The recess (9) together with the opening (10) and partitions (7a) form a seat (11). The connection of the walls (5 and 6) of the thermal break (1) is ended with feet (12) on both sides. The feet (12) are placed and crimped in the sockets (13) of the thermal breaks (1) of the aluminum outer section (2) and the aluminum inner section (3). On both sides, the outer wall (5a and 5b) of the spacer (1) to be recessed (9) is inclined in relation to the inner wall (6) of the spacer (1) and moves away from it towards the center of symmetry (14) of the spacer (1). The inner wall of the spacer (6) under the partitions (7a) forming the seat (11) has L-shaped projections (15) facing inwards. Between the protrusions (11) in the center there is a rail for the H-shaped bolt (16). The protrusions (15) together with the rail (16) form a seat (17) for the U-shaped mounting block (18). In the axis of symmetry (14) ) of the spacer (1), the right side (1a) of the spacer is a mirror image of the left side (1b).
