FIELD: building, particularly joint members adapted to connect chamfered profiles of window, door and facade frames. ^ SUBSTANCE: joint member is shaped as double dovetail and is inserted in profile grooves from inner joint side. The joint member is made of heat-shrinkable material. Ferromagnetic powder is introduced in central joint member part. Ferromagnetic powder may be heated by electromagnetic field to be generated for profile fixation. ^ EFFECT: increased efficiency. ^ 2 dwg |
