Definitions

  • Corner connector mold elements will be inserted into a hollow chamber of the respective plastic hollow profile section and fixed in the hollow profile section by injection of adhesive from the exposed plane of the miter section, so that a respective welding mirror is positioned flush with the corner joint forming element in the miter plane.
  • the corner connector form elements are connected to each other, so that together they form a arranged in the corner of the frame or the wing, winkelfömiges corner joint angle element.
  • the corner joint angle elements only need to absorb a portion of the forces, since the profile webs surrounding them are likewise welded to the profile webs of the adjacent hollow profile, so that forces can also be transmitted via them.
  • the object of the present invention is to specify a method for the in-situ production of a corner joint angle element on mitred window and door profiles, by which a mechanically loadable profile connection of metal profiles and in particular composite profiles made of plastic and metal is made possible.
  • the inventively used Eckverbinder-Gelloformieri are not prefabricated sub-elements that are combined by mere joining to a corner joint angle element, but that they form together with the surrounding walls of the profile chamber mold shells to the way of plastic injection molding a corner joint angle element to produce from thermoplastic material directly within a cavity in the frame or wing profiles.
  • the corner connector casting mold elements used become indirectly part of the corner connector angle element by adhesion and / or superficial fusion with the injected plastic melt; but they are not statically determinative in this composite. Structurally effective in the corner region of the profile sections connected with such a method is mainly made of two mold elements and the injected plastic mass in-situ corner joint angle element.
  • An in-situ production means that the corner joint angle element according to the invention is not prefabricated in a separate manufacturing process and that also not simply two prefabricated halves are glued together prior to assembly of the profile pieces, but that the corner joint angle element within the cavity the already correctly positioned adjacent plastic hollow profile sections is made, which is completely invisible from the outside.
  • thermoplastic polymer composition tends to shrink on cooling, but at the same time is hindered by material bond and / or positive connection with the casting mold elements and profile walls surrounding it.
  • suitable material pairings are used for the thermoplastic material of the hollow plastic profiles and for the plastic compound to be injected, with which this effect can be used particularly well.
  • the result is frozen shrinkage stresses in the in-situ manufactured corner joint angle element. Warms up with the inventive Process manufactured window or a door in use, for example, by strong sunlight, relax the shrinkage while partially. However, the remaining portions of the inherent shrinkage stresses ensure that the profile cut surfaces are held together in the miter plane, and in particular also on the metal profile half shells arranged on the outside. This prevents opening of the miter joint when heated.
  • the hollow chambers of the profile are in each case completely shut off, so that the volume to be ejected is limited.
  • the inlet opening may, for example, be in the area of the miter plane.
  • outlet openings should be provided, each of which lies in the rear regions of the hollow chambers bounded by the sealing sections, away from the miter plane. These ensure, on the one hand, that the air can escape completely during injection and that air bubbles trapped in the corner connection element are avoided. On the other hand can be achieved by a suitable dimensioning of the outlet openings, that the high-viscosity plastic melt flows into the outlet openings and there with the solidification a positive anchoring of the corner connector-casting element is effected on the hollow profile section, on the other hand, too much plastic melt into the adjacent hollow chambers or Outside flows out.
  • a suitable for performing the method corner connector-casting element specifies claim 8.
  • FIG. 1 shows a corner connector-casting element 10, which is preferably formed in one piece from a block body 1 made of plastic. This has lateral edging webs 1.1, but is hollow in between and open to the bottom to form a cavity 2 with the adjacent profile walls, can be injected into the plastic mass.
  • the block body 1 has at its one, in Fig. 1 rear end a plurality of parallel sealing collar 4 to completely shut off the cross section of a hollow profile chamber into which the corner connector mold element 10 is inserted. At this end, the open in the front areas cross-section of the cavity 2 is completely closed off, preferably via a wall on the rear end side. 6
  • the block body is chamfered according to the miter angle of a miter G. There opens the cavity 2, which is encompassed by the U-shaped block body 1.
  • the block body 1 has on its outer peripheral sides a plurality of the distance to the wall of the hollow profile chamber bridging spacer elements 5 and can also serve the anchoring of an injected into the profile cavity 2 plastic compound.
  • a centrally arranged profile hollow chamber 3 can be provided in the cross section of the cavity 2 in order to act as a displacer in this area to act the plastic melt. It can also be deliberately provided, for example by selecting suitable wall thicknesses, to make the hollow profile chamber 3 easier to deform, so that in the case of an overpressure during injection, which is accompanied by a marked increase in temperature by the injected plastic melt, the walls of the hollow profile chamber 3 deform first leave, but not the adjacent walls of the window or door profile, in which the corner connector mold member 10 is inserted.
  • Fig. 2 shows a positionally correct combination 10 'of two corner connector mold elements 10, which are placed in mirror image with respect to the miter G together.
  • Fig. 3 is a view from the miter plane G forth on a hollow profile section 20 of a frame profile shown.
  • This comprises a hollow plastic profile 21 made of thermoplastic material, in particular of rigid PVC, and on both sides set metallic shells 22, 23.
  • a hollow profile chamber 24 in the plastic hollow section 21 is initially used in door and window construction with plastic profiles usual reinforcing profile 30 made of sheet steel.
  • FIG. 4a shows a corner joint of two composite profiles 20, which have already been mitred according to the first method steps and each provided with a corner connector-casting element 10.
  • the cutting plane extends in FIG. 4a in each case by a hollow plastic profile 21 as a core profile, the metallic reinforcing profile 30 and a combination of two Eckverbinder-G manformieri10.
  • the view of the metallic attachment shell 23 is free.
  • the contiguous in the miter G edges of the attachment shells 23 have no direct connection with each other, and also the adjacent Eckverbinder-G adaptformieri 10 are not yet connected. They are only connected by the in-situ production of a corner joint angle element according to the inventive method to a statically resilient corner joint angle element.
  • the vents 7 have an important function for the method according to the invention. On the one hand, they serve to recirculate the air that is forced into the hollow chamber 2 when the plastic melt is injected dissipate the outside and thereby avoid blistering within the resulting plastic body in Hophlraum.
  • Fig. 4b shows, injected into the cavity 2 plastic melt 9 but also through the vent opening 7 to the outside, so pushed beyond the outer surface, where it swells, so that mushroom-like thickening 9.1, 9.3 form. Also in the area of the injection opening 8, when the injection nozzle is retracted, some melt may remain in the opening 8, so that a supernatant 9.2 results there as well.
  • the supernatants and thickenings 9.1, 9.2, 9.3 each cause a positive anchoring of the solidifying from outside to inside melt in the openings 7, 8.
  • the positive anchoring in the outer areas is already effective when the inner regions in the injected portion of plastic mass 9 still warm and correspondingly soft. With complete solidification and cooling shrinkage stresses thus form in the plastic mass 9, so that due to the positive anchors at the points 9.1 ... 9.3 at the same time the hollow profile sections 20 are drawn to each other on the miter G.
