! window frames.

It is known to cut the hollow on (xehxung Profile rods to form rectangular window frames at the ends by means of suitable angle pieces that are inserted into the Reach into the hollow spaces of the profiles, define * With plastic profiles, the ropes are connected to each other glued »

With windows made of plastic or metal turn out to be simply glued-in angle pieces are often not considered sufficient. For large. -Frame parts, the Corner connections often have large uncontrollable thermal stresses that lead to the cut edges of the frame parts in the so-called (guide joint not connect exactly to each other. Besides that Water can penetrate the joints »that too bothers good looks.

It is therefore the task of the .fire to work together connected and glued parts under tension to be fixed to each other and at the same time to improve the glue adhesion *

According to the fire, both legs have a sdLeh. known fitting In: the hollow ends of the profile · * · rods ■ inserted. The circumferential glue catching grooves around the elbow are also provided for the longitudinal extension of the frontal tabs, which are guided through the sidepieces of the glue catching grooves in the lengthways of the profiles, in that specially designed tabs are driven in as angled pins cüie two connected obliquely: truncated ErofIlstäbe be gedritekt in the miter joint tightly against each other * This is in etnfaehster catfish characterized errelcM "that the Fasßstlfte sth% s & ge ^rtirämt: slnd and: on. their surface are knurled in the longitudinal direction and "on. both face surfaces have a -slot or similar mark" which indicates the blocking of the recess ^ r the success and the back, against which the contra-angle supports »~

The surface of the bass pegs is roughened or knurled, for example, or has at least one longitudinal, sharp-edged surface so that it cannot turn in the borehole when it is driven in. The knurling or the above-mentioned longitudinal thread cuts into the heavy duty material, e.g. light metal or plastic, and thus prevents the ball pin from twisting when. Driving into 3rd & ΪΙ drilling channel

In the two mitered hohfen window profiles! 1 and 2 "whose cavity quadrangular cross-sectional shape, are the _Ti belden legs 3, and 4 of the angle-piece fitting inserted. Before inserting, the legs and / or the inner surfaces of the Erofile are coated with an adhesive which, after setting or gelling, retains its own elasticity, even if it is only slight. This elasticity, which in itself promotes tension compensation, is, however, entirely undesirable during the bonding time of the adhesive. It is even advantageous »if they are pressed together with gate tension. Then the miter joint is practically non-existent even with unfavorable thermal stresses * - ~ - - ^ - _;: ., __

The means for producing the bias is according to the price increase in the arrangement of dowel pins with little curvature; which the miter joint of the interconnected profiles in Bichtung; to bring the G honor structure under tension. If you want, you can do it after setting Remove the glue from the pegs and he laughs at the Bohr close with a suitable putty. But it is useful and labor-saving when used as a means of tightening Dowel pins - "stay in place *"

In further training of the firing, the glue surfaces are given circumferential grooves of the contra-angle handpiece 5 or the catch notches S, which are located when the Fill the elbow into the profile ends with free and ensure good glue wetting of the contact surfaces

The dowel pins 7 are formed by the arrangement of grooves or at least one over the back of the curved Pen extending rib 8 and before and after driving in the pen indicating its curvature Marking, e.g. a notch 9 »on both faces of the dowel pin. Me concave Side of each dowel pin 7 is the inspection joint y - y of the two profiles 1 and 2 are facing · This will be the two profiles are pressed against each other with prestress in the visible joint.
