Definitions

  • the invention relates to a window or door construction, with a casement frame and a stationary frame containing an aluminum composite profile, the composite profile containing three interconnected profile rails and chambers located one behind the other in the heat transfer direction.
  • the invention relates to an aluminum composite profile for the production of window or door structures.
  • Metal frames for windows and doors are already known which are insulated against the passage of cold by inserting a web made of heat-insulating material, in particular made of plastic or hard rubber, between an outer profile rail and an inner profile rail (AT-B-200 312) .
  • thermal insulation webs For reasons of strength, the choice of material and dimensions of thermal insulation webs are limited, which is why only limited thermal insulation is achieved with such composite profiles. Experience has shown that condensation can nevertheless form if there is a large temperature difference between the outside and the interior of the room. In the case of higher requirements for thermal insulation - for example in connection with triple glazing - such known composite profiles are unsatisfactory.
  • a composite profile is known from DE-A-2915255, in which three profile rails are connected by clamping elements.
  • the pairs of clamping elements are pressed apart by wedges and thereby clamped on projections of the profile rails.
  • the air chambers formed between the profile rails are covered on both sides by elastic cover profiles.
  • the fixed frame - also called frame - and the sash frame are constructed identically, with two opposing cover profiles sealingly abutting each other.
  • the object is to be achieved to create a window and door construction or an aluminum composite profile for their manufacture, with or with which a simplification of the profile rail design for the formation of two consecutive in the heat transfer direction, serving the increased thermal insulation air chambers is made possible.
  • FIG. 1 An embodiment of the object of the invention is shown.
  • the drawing shows a section through a window construction.
  • a stationary metal frame 1 also known as a frame, interacts with a casement 2 made of wood, which is provided with insulating glass 3, in the present case with three glass panes 5 held together by seals 17.
  • the frame 1 is attached in the usual way to a wall 4 or a stationary wooden frame 11 and connected by screws or the like, not shown.
  • the sealing against the metal frame 1 is carried out by means of sealing strips 30, 32, 34, for example made of rubber or plastic.
  • the frame 1 contains three aluminum profile rails, namely an outer profile rail 6, a middle profile rail 7 and an inner profile rail 8.
  • the outer profile rail 6 and the middle profile rail 7 are rigidly connected to one another by a first thermal insulation strip 9 of approximately rectangular cross-sectional shape.
  • This thermal insulation strip 9 engages in a groove 23, which are formed by legs 22 of profile rails 6 and 7 which are U-shaped in cross section.
  • the rigid fastening of the thermal insulation strip 9 in the two grooves 23 takes place, for example, by clamping and / or gluing.
  • thermal insulation strip 10 of approximately rectangular cross-sectional shape, which engages in grooves 25 of the rails 7 and 8. These grooves 25 are formed by U-shaped legs 26 in the rails 7 and 8.
  • the rigid fastening of the thermal insulation strip 10 in the grooves 25 takes place, for example, by means of a clamping action and / or gluing.
  • the two thermal insulation strips 9, 10 extending over all four sides of the frame are thus arranged one behind the other in the direction of heat transfer, where J denotes the inside of the room and A denotes the outside.
  • the thermal insulation strip 10 facing the inside J preferably has the same thickness as the other thermal insulation strip 9, but a slightly smaller width.
  • the thermal insulation strip 9 has, for example, a cross-sectional area of approximately 100-125 mm 2
  • the thermal insulation strip 10 has a cross-sectional area of approximately 80-100 mm 2 . Both are preferably made of rigid, glass fiber reinforced polyester plastic.
  • the thermal insulation strip 10 runs at right angles to the window surface; the other thermal insulation strip 9 is slightly inclined outwards, so that the two thermal insulation strips 9, 10 form an angle of 3 ° -10 ° to one another, preferably about 6 °.
  • the fork-shaped legs 22 and 26 of the central profile rail 7, which protrude on opposite sides, for receiving the two thermal insulation strips 9, 10 are arranged offset in height from one another.
  • the wing frame 2 which is preferably made of wood, contains several steps with - in horizontal cross section - horizontal step sections 18 and vertical step sections 20.
  • a first chamber 12 and a second chamber 14 separated from it are formed on all four sides, which are formed by an elastic one Sealing strips 16 are divided with a sealing lip resting against the central vertical step part 20.
  • the first chamber 12 is thus delimited by a web 36 of the profile rail 6 running approximately parallel to the plane of the glass panes 5, by the first thermal insulation strip 9, by the sealing strip 16 and by the middle step 18, 20 of the casement 2.
  • the second chamber 14 is delimited by the sealing strip 16 with a sealing lip, by the middle profile rail 7, by the second thermal insulation strip 10, by the leg 40 of the inner profile rail 8 and by a step of the casement 2.
  • the middle profile rail 7 contains one upward or towards the sash frame 2 opening groove 38 for receiving the sealing strip 16.
  • the web 37 of the central profile rail 7 protrudes beyond the U-shaped legs 22 of the thermal insulation strip 9, but ends somewhat below the horizontal step part 18 of the frame 2.
  • the vertical Step part 20 of the casement 2 close to the inside of the room J, bears against the inner profile rail 8.
  • a continuation of the profile rail 8 projects downward, its lower end being directed against a wooden frame 11. According to the steps 18, 20 of the casement 2, the legs 36, 37, 40 are graded to one another.
  • a temperature difference in the heat transfer direction i.e. between the inside J of a window or a door and the outside A, is thus broken down in two successive, heat flow-separated stages, with a thermal insulation value K of about 1.8 kcal / m 2 h C ° being achieved , which corresponds to standard triple glazing.
  • Such a frame construction is well suited for the renovation of existing windows, whereby the usually existing wooden frame 11 can remain on the building.
  • the frame 1 can also be used for building exterior cladding or the like in addition to windows and doors.
