Definitions

  • the invention relates to a profile system for the production of windows or doors on the basis of plastic profiles with a reinforcement profile, as well as windows and doors produced from such a profile system.
  • Hollow chamber profiles for the production of windows and doors are extruded from PVC molding compounds on a large scale. In order to meet the structural requirements of the window elements, they are usually reinforced with steel reinforcement profiles.
  • the reinforcement profiles lie completely against the inner contour of the reinforcement chamber.
  • the PVC profile warps before the reinforcement profiles are subjected to bending stress and thus develop their reinforcing effect.
  • the hollow chamber profiles and the reinforcement profiles are firmly connected to one another, preferably screwed.
  • the reinforcement profiles are inserted into a so-called reinforcement chamber of the hollow profiles - in particular the frame profiles for the frame and the sash frame profiles for the sash frame - before welding the PVC profiles cut to length and mitered and screwed to the hollow profile with a screw connection that penetrates the outer contour of the hollow profile . This is usually done by the window manufacturer.
  • the invention is based on the object of creating a reinforcement profile for a plastic window profile with at least one reinforcement chamber which can also be connected to a corresponding plastic window profile without a screw connection.
  • the object is achieved by a reinforcement profile having the features of independent claim 1 and by using a method having the features of claim 9.
  • a reinforcement profile for a plastic window profile which has at least one reinforcement chamber, the reinforcement chamber being suitable for receiving the reinforcement profile
  • at least one compressible sealing profile is arranged on at least one surface of the reinforcement profile.
  • the compressible sealing profile serves as a force-fit connection between the reinforcement profile and the plastic window profile, so that there are no shifts between the reinforcement profile and the plastic window profile during normal handling without additional fasteners such as screws.
  • the sealing profile is always positioned in the right place and cannot be lost, in a preferred embodiment it is firmly connected to the reinforcing profile, preferably extruded onto it.
  • the sealing profile can be glued on or fixed in a groove.
  • the compressible sealing profile is a tubular sealing profile
  • the seal is under tension as soon as it is compressed. Since the sealing profile then tries to go back to its original shape, it exerts pressure on the devices, whereby the static friction opposes this urge to move.
  • the reinforcement profile in the direction of extent is somewhat larger than the cross section of the reinforcement profile in the direction of extent, the reinforcement profile can be accommodated in the recess with play.
  • the direction of extent is understood to mean the direction of extrusion.
  • the direction of extension is understood to mean the direction in which the longest edge of the profile runs.
  • the sealing profile should have a height h, which in the uncompressed state is greater than the play between the plastic window profile and the recorded reinforcement profile exists at the location where the sealing profile is arranged. This ensures that the sealing profile presses the reinforcement profile against the receiving plastic window profile.
  • the tubular sealing profile can be closed at one end.
  • the sealing profile is preferably hot-formed at this point.
  • the cross section of the sealing profile can be essentially rectangular in the direction of extent. If one side wall has a smaller thickness than the opposite side wall, this has the advantage that the sealing profile buckles in a defined manner when it is loaded. To form a rectangle, three sides arranged essentially at right angles to one another are sufficient, since the fourth side can be taken over by the reinforcement profile to which the sealing profile is attached.
  • the sealing profile can optionally be compressed by generating a negative pressure inside the hose profile.
  • the sealing profile can be relieved of the compressive forces at a later point in time by increasing the pressure inside the hose profile; the interior of the hose profile is preferably subjected to ambient pressure.
  • the sealing profile is initially drawn together in this way, whereby the reinforcing profile with the contracted sealing profile can be introduced into the reinforcement chamber of the plastic window profile.
  • the sealing profile nestles against the inner wall of the reinforcement chamber, so that an immovable connection is created.
  • the method is particularly effective if the sealing profile is closed at one end, while a device for generating a negative pressure is connected to the other end of the sealing profile.
  • the sealing profile can be compressed mechanically, preferably by means of a band.
  • a thin flat band can be drawn over the sealing profile in the direction of extent. Then the reinforcement profile is inserted and finally the ribbon is pulled out.
  • FIG 2 the same plastic window profile 1 is shown with a reinforcement profile 2 according to the invention in the reinforcement chamber 4.
  • a compressible sealing profile 3 is arranged on the upper surface of the reinforcement profile 2.
  • the compressible sealing profile 3 is an extruded tubular sealing profile 3, which in the reinforcement chamber 4, the space between the reinforcement profile 2 and Plastic window profile 1 bridged and thus the reinforcement profile 2 presses against the plastic window profile 1.
  • the reinforcement profile 2 is preferably made of glass fiber reinforced plastic, so that it can be extruded.
  • the pre-extruded sealing profile 3 can be co-extruded directly with the reinforcement profile 2 or post-co-extruded afterwards.
  • the reinforcement profile 2 can also be made of steel or aluminum; the sealing profile 2 is then subsequently extruded into a groove in the reinforcing profile 2.
  • the cross section of the reinforcement chamber 4 in the plastic window profile 1 in the direction of extension is slightly larger than the cross section of the reinforcement profile 2 in the direction of extension, so that the reinforcement profile 2 can be accommodated in the recess of the reinforcement chamber 4 with play. This is necessary in order to be able to introduce the reinforcement profile 2 into the plastic window profile 1.
  • the reinforcement profile 2 with an extruded tubular sealing profile 3 is insulated in FIG Figure 4 shown.
  • the cross section of the sealing profile 3 is essentially rectangular in the direction of extent, the left side wall 31 having a smaller thickness than the opposite right side wall 32.
  • the cross section of the sealing profile 3 may have a different shape, such as that of a bellows or a rhombus, for example.
  • the sealing profile 3 has a height h which, in the uncompressed state, is greater than the play that exists between the plastic window profile 1 and the received reinforcing profile 2 at the location at which the sealing profile 3 is arranged. As a result, the sealing profile 3 remains in the assembled state in a compressed state with a height which is smaller than the unloaded height h and exerts a compressive force on the connection between the plastic window profile 1 and the received reinforcement profile 2.
  • the sealing profile 3 is first compressed by inserting a lance 6 into the tubular sealing profile 3.
  • the lance 6 is connected to a vacuum pump 7.
  • the vacuum pump 7 sucks the air out of the interior of the tubular sealing profile 3, so that a negative pressure is created in relation to the surroundings and the sealing profile 3 contracts. Due to the fact that the sealing profile 3 is closed on the side facing away from the lance 6, no air can flow into the sealing profile 3. Since the left side wall 31 of the sealing profile 3 has a smaller thickness than the opposite right side wall 32, the sealing profile buckles in a targeted manner on the left side and hugs the reinforcement profile 2.
  • the reinforcement profile 2 can now be introduced with the compressed sealing profile 3 into the reinforcement chamber 4 of the plastic window profile 1.
  • the lance 4 is pulled out of the sealing profile 3.
  • the sealing profile 3 has an uncompressed height h, which is larger than the gap between the reinforcement profile 2 and the plastic window profile 1, the sealing profile 3 strikes in a compressed manner in the reinforcement chamber 4 and thus presses the reinforcement profile 2 against the plastic window profile 1, whereby the reinforcement profile 2 is non-positively and positively connected to the plastic window profile 1 and can only be moved relatively under extremely high force. Moving under gravity or other usual conditions - for example when handling the profiles in a manufacturing center - is therefore excluded.
  • a reinforcement profile can be assembled in a frame profile in order to save the window builder preparation time and work.
  • the invention is not limited to the exemplary embodiment.
  • it is not limited to frames, but can also be used for casement frames, both for windows and doors.
  • one profile can accommodate several reinforcement profiles.
  • One or more sealing profiles 3 can be arranged on a reinforcement profile 2.
