Definitions

  • the invention relates to a method for producing a hollow chamber profile, in particular a window or door hollow chamber profile, wherein by means of an extrusion process, a hollow profile is produced with at least one hollow chamber.
  • Such a method is for example from the DE 41 31 816 A1 known.
  • a foam profile is glued to a reinforcing profile made of metal and inserted together with this in the hollow chamber of the hollow chamber profile in the known method. Due to the required metal reinforcements, the thermal insulation properties of this known profile are limited overall.
  • the invention has for its object to provide a method with the features described above, which can be equipped in a simple and reliable manner with an additional element, preferably with a thermal insulation element.
  • the hollow chamber wall is equipped with at least one extending in the extrusion direction guide member and at least a separate functional element is inserted into the hollow chamber of the extruded hollow chamber profile, wherein the functional element during this insertion process in the manner of a tongue and groove system of the guide element to be led.
  • the insertion process of the functional element is considerably facilitated by means of the guide element.
  • the spring engages in a precisely fitting groove.
  • Tongue and groove can in this case have a rectangular geometry, although other matching geometries are within the scope of the invention (for example, dovetail geometry). Due to the matching design of the guide element and the functional element no slippage of the functional element during the insertion process is to be feared, so that an exact positioning of the functional element is ensured. By accurately fitting design expediently fixed the guide element, the functional element in the retracted position.
  • the guide element here assumes two tasks, namely on the one hand, the guide during the insertion process and beyond the fixation of the functional element in its final position, so that usually no additional fixing elements are needed.
  • the functional element expediently has a slight oversize compared to the assigned hollow chamber geometry. It is also within the scope of the invention for the fixation of the functional element to be effected via an additional means, e.g. an adhesive takes place.
  • the functional element is designed as a thermal insulation element.
  • the thermal insulation element contains insulating material made of an organic or inorganic foam with low thermal conductivity.
  • Suitable organic materials are in particular foamed polystyrene, polyvinyl chloride, polyethylene, polyurethane or mixtures of two or more of the materials mentioned.
  • Suitable inorganic materials are, in particular, foam, glass or a nanoporous sealant (for example Vacupor® company POREXTHERM).
  • the thermal insulation element fills only a part of the hollow chamber, so that a free space remains in the inner and / or in the outer edge region of the hollow chamber.
  • This additional space if it is dimensioned accordingly, an additional thermal insulation function, since it forms an additional Dämmhunt.
  • the thermal insulation function is given in particular if the width of the free space is 2 to 8 mm, preferably 3 to 7 mm. This ensures that free convection of the air in these free spaces is sustainably restricted and these open spaces have a good, additional thermal insulation function.
  • an inner coating with respect to the heat-insulating increased radiation reflection is provided on the inside of the heat-insulating element, preferably.
  • an outer coating is provided with a reduced emissivity relative to the heat-insulating element, preferably in the wavelength range of 9-11 ⁇ 10 -6 m.
  • the aforementioned coatings also contribute to the improvement of the thermal insulation properties of the entire hollow chamber profile.
  • the functional element may comprise a reinforcing element, e.g. made of fiber-reinforced plastic or metal, or a, preferably porous, soundproofing element.
  • the functional element can also be designed as a fan, dryer or electronic control element which, for example, expanded the function of the window / door.
  • the reinforcing element is integrally connected to the hollow chamber profile. As a result, the stiffening effect of the reinforcing element is increased.
  • the guide element is designed as protruding into the hollow chamber projection. Accordingly, the functional element then has a corresponding recess for this purpose.
  • the guide element may be formed as a recess in the hollow chamber wall and the functional element have a projection corresponding thereto.
  • the guide element has a width of at most 10 mm, preferably at most 5 mm.
  • the guide element has a dovetail geometry, whereby a particularly good guidance is ensured.
  • designs in which the guide element has an undercut also fall under the teaching of the invention.
  • the hollow chamber profile with at least one additional reinforcing tape for example made of metal (aluminum or steel), or of a fiber-reinforced plastic, eg an organic sheet (thermoplastic prepreg with continuous fibers) exist.
  • the hollow chamber profile at least partially consists of fiber-reinforced plastic, with glass fibers and / or carbon fibers being considered as reinforcing fibers in particular.
  • the functional element is designed as a polymer profile, which consists of a weldable plastic. This can be welded to the corresponding hollow chamber profile in particular in the corner regions of a framework composed of hollow chamber profiles. As a result, the torsional rigidity of the entire frame can be increased, which is of particular importance in the case of door frames (for example for front doors), so that a stabilizing steel reinforcement can possibly be dispensed with.
  • the invention further provides a hollow chamber profile according to claim 14.
  • the FIG. 1 shows a hollow chamber profile 1, which is used for windows and / or doors.
  • a hollow profile 2 having a plurality of hollow chambers 3, 3 'was first produced.
  • the hollow chamber profile 1 is made of plastic, such as rigid PVC.
  • the wall of the hollow chamber 3 has two extending in the extrusion direction guide elements 4.
  • a separate functional element 5 is inserted in the corresponding hollow chamber 3 of the extruded hollow chamber profile 1. This is performed during the insertion process of the guide elements 4 in the manner of a tongue and groove system.
  • the guide elements 4 and the functional element 5 have a rectangular geometry and are matched to one another in a precisely matching manner so that the guide elements 4 fix the functional element 5 in the inserted position.
  • the functional element 5 can have a certain oversize relative to the associated hollow chamber 3.
  • the functional element 5 is formed as a thermal insulation element, wherein the thermal insulation element 5 insulating material 6 of an organic foam with low thermal conductivity, eg PUR foam containing.
  • the heat-insulating element 5 fills only a part of the corresponding hollow chamber 3, so that in each case a free space 7 remains both in the inner and in the outer edge region of the hollow chamber 3.
  • the width s of this free space 7 is 2 to 8 mm, for example 3 to 7 mm, in particular 4 to 6 mm.
  • an inner coating 9 is provided with respect to the thermal insulation element 5 increased radiation reflection, which esp. In the wavelength range of 9 - 11 x 10 -6 m relative to the thermal insulation element 5 has increased radiation reflection.
  • On the outside 10 is an outer coating 11 with a ggü. the heat insulation element 5 esp.
  • the two layers 9, 11 additionally contribute to the improvement of the thermal insulation properties of the entire hollow chamber profile 1.
  • the functional element 5 has an additional reinforcing element 12 on both edges. This consists for example of GRP, aluminum or steel. In this respect, the functional element 5 in FIG. 1 In addition to the thermal insulation additionally the task of increasing the mechanical stability of the entire hollow chamber profile 1.
  • the guide elements 4 are formed as protruding into the hollow chamber projections. The width b of the guide elements 4 is less than 3 mm.
  • the hollow chamber profile 1 is provided with reinforcing bands 13 for the purpose of increasing the mechanical stability. These may, for example, be extruded into the wall of the hollow chamber profile 1.
  • the Arm istsb section 13 may be made of metal, for example aluminum or steel, but in particular also consist of a fiber-reinforced plastic, such as an organic sheet.
  • Also in the FIG. 2 fills the heat-insulating element 5 only a part of the hollow chamber 3, so that both in the inner and in the outer edge region of the hollow chamber 3, a free space 7 remains. Again, the width s of the free space 7 is preferably 3 to 7 mm.
  • the guide elements 5 are formed as a recess in the hollow chamber wall and have a dovetail geometry.
  • the width b of the guide elements 5 is less than 5 mm.
  • the hollow chamber profile 1 at least partially or even completely consists of fiber-reinforced plastic, in particular provided with glass and / or carbon fibers. On the usual metal insert can therefore be omitted as a rule.
