Definitions

  • the invention relates to a preferably extruded window or door hollow chamber profile according to the preamble of claim 1.
  • a hollow chamber profile has at least one reinforcement chamber which is designed and provided for receiving a preferably metallic reinforcement element.
  • the invention also relates with claim 14 to a system made up of an (extruded) window or door hollow chamber profile according to the invention and at least one reinforcement element, preferably made of metal.
  • the invention further relates to a frame for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention that are connected to one another in connection areas, preferably welded.
  • Window profiles known on the market have insulating chambers which, in the mounted state, follow one another from the outside (outside) inwards (inside) or are arranged next to one another.
  • One or more of these chambers can be equipped with metal profiles (reinforcing elements) to increase the stability of the window.
  • Such chambers are then referred to as reinforcement chambers.
  • the reinforcement chambers are regularly covered with only one (PVC or generally plastic) wall on the other two sides of the profile (top and bottom or to the window opening and to the structure/masonry), so that a screw connection to or through the reinforcement is possible can be done directly.
  • FIG 1 Various previously known hollow chamber profiles 1 with inserted reinforcement 2 are shown, namely both casement profiles (each above, with inserted glazing 3) and window frame profiles (each below, for attachment to a structure).
  • casement profiles each above, with inserted glazing 3
  • window frame profiles each below, for attachment to a structure.
  • the outside is on the left, while the inside is on the right.
  • isotherms ie lines of the same temperature. Inside the wing (top) the isotherms run closer to the outside of profile 1 - for example, isotherm IL1 runs to the left of reinforcement 2; in the frame (below) the same isotherm IL1 is closer to the inside of profile 1 or to the right of reinforcement 2.
  • the desired ideal state of thermal insulation is when there is an even and regular distribution of the isotherms and the isotherms have an almost straight, vertical course without distortions or horizontal parts (outside-inside).
  • the invention is therefore based on the object of further developing a hollow chamber profile of the type mentioned at the outset such that good thermal insulation or thermal insulation that is improved compared to the prior art can be achieved even if metallic reinforcement is provided.
  • the object is achieved according to the invention by a window or door hollow chamber profile with the features of claim 1, by a system with the features of claim 14 and by a frame with the features of claim 15.
  • a window or door hollow chamber profile which hollow chamber profile has at least one reinforcement chamber, which is designed and provided for receiving a preferably metallic reinforcement element, characterized in that the reinforcement chamber is at a clear distance on at least two sides of an arrangement of at least two and profile webs extending parallel to one another.
  • a system according to the invention consisting of an extruded window or door hollow chamber profile according to the invention and at least one reinforcement element, preferably made of metal, it is provided that the reinforcement element is introduced into the reinforcement chamber.
  • a preferably metallic reinforcing element is preferably inserted into at least one of the respective reinforcing chambers.
  • thermo jacket The arrangement provided according to the invention of at least two profile webs extending parallel to one another and at a clear distance from one another on at least two sides of the reinforcement chamber is also referred to here as a "thermo jacket".
  • the thermal jacket additionally insulates and insulates the reinforcement chamber from the rest of the profile. This improves the thermal insulation of the profile itself. Said clearance is preferably between 3 and 10 mm and most preferably even less than 6 mm. This reduces the occurrence of convection, which is negative from a thermal point of view.
  • a further development of the hollow chamber profile according to the invention is particularly advantageous, in which the reinforcement chamber is even on three sides of an arrangement is surrounded or formed from at least two profile webs (thermo jacket) extending parallel to one another.
  • the insulating effect is further improved by
  • the hollow chamber profile according to the invention in which at least one profile web, which faces an interior space of the reinforcement chamber, has a number of projections on its inner side facing the reinforcement chamber.
  • the reinforcement is thus kept at a distance from the profile web of the reinforcement chamber, which also improves the insulating effect.
  • the parallel profile webs are connected to one another in pairs via a number of intermediate webs. This creates additional stability without negatively affecting the thermal insulation properties.
  • the intermediate webs are oriented at an angle of 90 degrees to the profile webs connected by them. This has proven to be particularly advantageous under stability criteria; moreover, the amount of material required to manufacture the profile can be minimized.
  • the intermediate webs are oriented at an angle that is not equal to 90 degrees to the profile webs connected by them. Such an arrangement can be advantageous in particular in corner areas of the reinforcement chamber or the thermal jacket.
  • the hollow chamber profile provides that at least one screw chamber is formed by a number, in particular two, of the intermediate webs and a number, in particular two, of the profile webs or by a projection on a profile web, in which screw chamber the hollow chamber profile has an accumulation of material and / or has a wall thickening and / or an intermediate web.
  • Such screw chamber can be advantageous when attaching the profile to a structure or when attaching additional components (e.g. fittings) to improve the holding effect.
  • this means a delimited space within the profile, through which a fastening means (in particular a screw) profiled on the edge can be guided, with which fastening means the profile is fixed to the structure or the component.
  • the screw chambers have dimensions which are selected in such a way that the fastening means interacts (engages) with walls of the screw chamber in order to favorably influence the holding effect.
  • the material accumulations or thickenings mentioned also contribute to this.
  • the thermal jacket insulates the reinforcement chamber from the rebate space or rebate area, so that the effect of the cold bridge formed by the reinforcement is reduced particularly well.
  • This can be seen from the isotherm curves, i.e. the lines of the same temperature, which now run through the reinforcement cross-section.
  • This is based on below figure 3 also shown graphically.
  • a temperature difference of, for example, >2°C can be achieved across the reinforcement cross-section, ie an insulating effect has set in.
  • connection area preferably extends vertically through the profile, namely--as I said--from the rebate area to the opposite side, which faces or faces the building in the case of window frame profiles and the window frame in the case of casement profiles.
  • a screw chamber is arranged in the fold area. In this way, the holding effect can be specifically increased in this area.
  • a screw chamber is arranged on an outside of the hollow chamber profile opposite the fold area. In this way, the holding effect can (also) be specifically increased in this area.
  • the two screw chambers mentioned are aligned along a connecting line that extends parallel to a side surface or lateral profile wall of the hollow chamber profile.
  • a fastener can be passed through the profile and through both screw chambers along the connecting line.
  • the reinforcement chamber is delimited on one side by a reinforcement integrated into the hollow chamber profile, in particular made of fiber composite material.
  • the stiffening itself is preferably spaced apart from an outer wall of the profile and thus becomes part of the thermal jacket, without additional expenditure of material being required for this.
  • the reinforcement mentioned is arranged on a side of the hollow chamber profile which is directed towards the inside of a building when installed as intended. Such a configuration has proven to be particularly well suited in practice.
  • the thermal jacket basically gives the attachment of fittings, etc. more support and grip, so that the corresponding screw pull-out values can be raised to a comparable level as with screw connections in metals. At the same time, processing is correspondingly faster.
  • the thermal jacket is preferably double-walled over the entire length of the reinforcement chamber, in a longitudinal (extrusion) direction of the profile, with thermal improvement preferably even taking place on three sides, as already described above.
  • thermal improvement preferably even taking place on three sides, as already described above.
  • the holding effect for a screw connection provided in this area is improved.
  • thermal jacket on all four sides of the armoring chamber.
  • figure 1 shows cross sections through conventional window profiles or hollow chamber profiles 1 (window frame and casement) according to the prior art with steel reinforcement 2 and with glazing 3 inserted in the casement frame.
  • figure 2 shows a cross section through a hollow chamber profile 1 according to the invention, which has been produced from a plastic material, in particular PVC, by extrusion, preferably along a longitudinal extrusion direction EL, which extends into the plane of the drawing.
  • the hollow chamber profile 1 has--in the illustrated assembled state--in the upper region of the hollow chamber profile 1 at reference number 1a an upper profile wall which is L-shaped and forms a so-called fold. In the case of the window frame profile shown here, this is to accommodate an edge area of a sash (not shown) (cf. figure 3 ) definitely.
  • Numeral 1b designates a lower profile wall, which faces a structural body, not shown.
  • Reference numeral 1c designates an inner lateral profile wall in the assembled state
  • reference numeral 1d designates an outer lateral profile wall.
  • the hollow chamber profile 1 has a plurality of hollow chambers, of which figure 2 only some are denoted by reference numeral 1e.
  • One of these hollow chambers 1e is significantly larger than the others and serves as a reinforcement chamber 4 into which a preferably metallic reinforcement element 2 can be inserted to reinforce the hollow chamber profile 1, which in figure 2 is shown in dashed lines.
  • the reinforcement element 2 can be made of steel, for example, without the invention being limited to this.
  • the reinforcement chamber 4 on at least two sides, according to the embodiment in figure 2 even on three sides, surrounded by a so-called thermal coat.
  • the reinforcement chamber 4 is formed on at least two sides by an arrangement of at least two profile webs which extend at a clear distance and (at least predominantly or essentially) parallel to one another.
  • the thermal jacket is provided with the reference number 5 and graphically highlighted.
  • Said profile webs comprise in an upper area of the thermal jacket 5 a section of the profile wall 1a and a transverse web provided with the reference number 6, which is arranged at a clear distance A1 from the profile wall 1a and is connected to it via intermediate webs 6a, 6b.
  • the intermediate webs 6a extend at an angle of 90° to the profile webs, while the intermediate web 6b extends obliquely to the profile webs.
  • the profile webs include two parallel vertical connecting webs 7.1, 7.2, which are located between the rebate area (profile wall 1a) and an outside of the rebate area (profile wall 1b) of the hollow chamber profile 1 extend in a connection area.
  • the connecting webs 7.1, 7.2 are connected via intermediate webs 7a; these extend transversely to the connecting webs 7.1, 7.2.
  • the connecting webs 7.1, 7.2 have a clear distance A2 from one another, which can be different from the clear distance A1.
  • the profile webs comprise two connecting webs 8.1, 8.2, which run essentially parallel to one another and are designed and arranged similarly to the connecting webs 7.1, 7.2.
  • a clear distance A3 between the connecting webs 8.1, 8.2 can be different from the clear distances A1, A2.
  • All profile webs mentioned can have the same or different wall thicknesses. In the present case, in particular, the profile web formed by the profile wall 1a is made significantly thicker than the remaining profile webs.
  • the distances A1-A3 are preferably between 3 and 10 mm. Most preferably they are each less than 6 mm, i.e. 3 to 6 mm, in order not to allow convection to develop.
  • the connecting web 8.2 is slightly bevelled at its upper end in the area of the profile wall 1a, so that in this area there is no exactly parallel course to the connecting web 8.1. However, such an embodiment should also be included within the scope of the present invention.
  • the connecting webs 8.1, 8.2 are also connected via intermediate webs 8a, as shown.
  • the connecting web 8.2 is supported laterally via further webs 9 on the inner, lateral profile wall 1c.
  • the relevant profile webs in this case the transverse web 6 and the connecting web 7.2, have projections 10 which, when the reinforcement element 2 is inserted, ensure that the reinforcement element 2 does not rest over the entire surface on the or all walls of the reinforcement chamber 4.
  • the hollow chamber profile 1 has an external projection 11, which extends transversely to the longitudinal direction of extrusion EL.
  • the approach 11 includes an intermediate web 11a and can be used as an additional Screw chamber for a (not shown) fastener, for example a fastening screw, which is passed through the hollow chamber profile 1 along a fastening axis BA in order to connect the hollow chamber profile 1 to the (not shown) structure (below in figure 2 ) connect to.
  • the thermal jacket 5 also acts as an additional screw chamber where the fastening axis BA intersects it, which improves the holding effect of the fastening means.
  • figure 3 shows essentially the same hollow chamber profile 1 as in FIG figure 2 , but among other things with inserted reinforcement or inserted reinforcement element 2.
  • Reference number 1' also shows a further hollow chamber profile, which is part of a casement frame with inserted glazing 3.
  • the casement profile 1' does not have a thermal jacket, but without the invention being correspondingly limited in principle.
  • the hollow chamber profile 1 according to figure 3 has reinforcements made of a fiber composite material that are integrated (co-extruded) into the hollow chamber profile 1 at the factory at reference numbers 12, 12'. According to the design in figure 3 forms one of these stiffeners 12 'the right boundary of the armouring chamber 4, while the armouring chamber 4 is formed above and on the left side substantially as above with reference to FIG figure 2 explained in detail. Said reinforcement 12' is supported laterally on the profile wall 1c via a web 12a.
  • An additional screw chamber 13 with additional projections/bulges 13a is formed between the connecting webs 7.1, 7.2 in the lower region, adjacent to the profile wall 1b.
  • the intermediate web 11a within the extension 11 is discontinuous, with the resulting projections extending obliquely with respect to the fastening axis BA.
  • the projections 10 within the armouring chamber 4 are shown in FIG figure 3 arranged in the upper area (on the crosspiece 6) and in the lower area (on the inside of the profile wall 1b).
  • the hollow chamber profile 1 has an additional screw chamber 14 aligned with the attachment 11 along the fastening axis BA, which is formed between the transverse web 6 and the upper profile wall 1a together with the relevant intermediate webs 6a. In this area, the hollow chamber profile 1 has additional material accumulations 14a in order to improve the holding effect of a fastening screw (not shown) introduced along the fastening axis BA.
  • FIG. 4 a section in or parallel to a glazing plane through a frame 20 for a door or a window, in particular a window frame, which consists of several sections 1.1-1.4 of hollow chamber profiles 1 according to the invention (cf. figures 2 and 3 ) is formed.
