Abstract (en)
[origin: EP0644312A2] Right-angle connecting structure for hollow sections cut at 45 DEG for the realization of door- and window frames, casings and the like, utilizing a set-square composed of two flat and superposed angle bars inserted into the ends of said sections and provided with a tensioning dowel to allow teeth protruding from an angle bar to insert stably into eyelets obtained in the walls of said sections; said structure being provided with wedge-shaped means for driving and restraining said dowel during the screwing, for the shifting of the upper angle bar on the lower angle bar, and with plug-in hooking means, obtained transversally on the matching faces of said angle bars, suitable to prevent, during the tensioning of said dowel, the rotation and/or shiftings of the flanges of the upper angle bar relatively to the lower angle bar, and to allow the regular engagement of said teeth into the relevant eyelets and the safe and stable locking of the sections with one another. <IMAGE>
