Definitions

  • the invention relates to a self-supporting insulation element for insertion between the panes of a double or composite window, consisting of a single coated film which is biaxially stretched longitudinally and stretched over a clamping frame, the sides of which are bent in the untensioned state according to a curve curved on one side.
  • an insulation element preferably for windows with a rectangular or square surface in the usual way, is known in which foils connected in pairs are stretched out in the manner described above via a tenter frame, the sides of which in the untensioned state relative to straight connecting seam of the two foils run according to a curve which is continuously curved on one side, preferably along the bending line of a uniformly loaded, non-clamped beam.
  • the object of the invention is to provide a way of making a single film in the desired manner, i.e. to be stretched biaxially in relation to the frame due to different thermal expansions.
  • the solution to this problem must also satisfy the following boundary conditions - already considered in the insulation element according to DE-OS 28 50 749:
  • the clamping forces do not become too large and not too small. Excessive clamping forces cause damage to the coating on coated foils, which creates starting points for increased corrosion attack; too small or irregular tension forces lead to wrinkles.
  • room temperature i.e. about 20 ° C
  • the clamping forces should be, for example, about 1 N / cm in length; ensuring suitable clamping forces should extend over a temperature range from -20 ° to + 50 ° C.
  • the insulation element should be self-supporting, so that the reaction forces of the film tension in composite windows do not have to be absorbed by the air and water vapor-tight and therefore very sensitive edge bond; a self-supporting insulation element can also be used in a simple manner in existing double windows.
  • the frame consists of a torsionally rigid profile which carries a guide strip on one side, through which at least one slide band which is stretchable in its longitudinal direction is displaceably held and guided along each side of the frame and in addition that the film with the slide band is over mutually separate adhesion points is connected in such a way that the adhesion points are offset relative to the plane of the stretched film towards the frame.
  • the film is firmly connected only to the sliding band; Different thermal expansions of the film and frame are therefore possible.
  • the required one-sided arrangement of the film causes asymmetrical force effects on the frame; this is therefore subject to torsional stress. Due to its torsional rigidity, this load is counteracted and a disruptive twisting of the profile is prevented.
  • the longitudinal extensibility of the sliding band which can also be ensured by its separation into individual sections, in conjunction with the separate adhesive points ensures that when the curved frame is stretched, the tensioning forces acting on the film are evened out over the entire length of one side of the frame.
  • the torsional stiffness of the frame can advantageously be achieved by a hollow profile closed in the circumferential direction; metals used as frame material are primarily used in window construction. However, it is also possible to use fiber-reinforced plastic frames with additional metal inserts if necessary.
  • the displacement takes place at least approximately through the last point of adhesion of the sliding band on one side and at least approximately in the longitudinal axis of the points of adhesion on the side perpendicular thereto, since this also means that the direction of action of the clamping forces at the corners is essentially perpendicular or parallel runs to the points of adhesion of the foils and the sliding tape, thus reducing the possibility of wrinkles.
  • connection of the film to the slide band is expediently carried out in the case of prestressed frames, in which the slide band is already inserted, by welding or gluing.
  • the glass panes 1 (FIG. 2) of a composite window are glued airtight and water vapor-tight on a metallic hollow frame 2 by means of a butyl adhesive and are surrounded on the outside by a waterproof and mechanically load-bearing seal 3; this consists, for example, of a silicone or a polysulfide polymer.
  • a frame 7 covered with a film 6 is inserted as a self-supporting insulation element between the panes 1 by means of a spacer 4 and a spacer 5; the film 6 is provided in a known manner with a coating consisting, for example, of a metal, such as gold or silver, which is transparent in the visible spectral range and highly reflective in the infrared. While the spacers 5 are each provided in the corners of the cavity 2 and have a recess for receiving the frame 7 in one corner, the spacers 4 are glued distributed over the long sides of the frame 7 on its rear side facing away from the film 6.
  • a large number of individual sliding elements 8 ′ are inserted on one side as a sliding band 8 and are held displaceably relative to the frame 7.
  • the sliding band 8 can also consist of one piece, the longitudinal extensibility of which is ensured by incisions 9 which are arranged at a distance and alternate from both edges.
  • the sliding band 8 or the sliding elements 8 ' are connected to the film 6 via individual, interrupted adhesive spots 10, which are, for example, individual welding or adhesive spots.
  • the torsionally rigid frame 7 has a closed hollow profile which has been produced, for example, by extrusion; the cavity of the profile is advantageously filled with a commercially available physical or chemical drying agent 11. Bores 22 in one of the cavity walls of the frame profile, preferably on the side covered by the sliding band 8, establish a connection between the drying agent in the interior of the hollow profile and the gas volume to be dried.
  • the hollow profile On one side of its square cross-section, the hollow profile carries on the outside a guide strip or slide-in rail 13 formed by bending its elongated edges 12 for receiving the sliding band 8 or the sliding elements 8 '.
  • a frame 17 can also have a profile such that the sliding band 18 or its elements are not pushed in, but rather are pushed onto a guide bar formed by longitudinal grooves 20, the displacement of the adhesion points 10 with respect to the plane of the stretched film 6 is ensured by a bead 19 present on the sliding band 18.
  • the foils 6 protrude beyond the frame 7 beyond the adhesion points 10 in loose tabs 21. These tabs lie against the hollow frame 2 of the window in the case of insulation elements installed in the window (FIG. 1) and thus prevent outside air circulation around the frame 7 around between the two subspaces in the window separated by the insulation element.
  • Two mutually perpendicular sides of the frame 7 are each connected to one another by corner pieces 24 (FIG. 4) fitted into their hollow profile; for tensioning the frame 7, each side is supported at one end on the angle of the corner piece 24, while its other end can slide on one leg of a corner piece 24.
  • the displacement of two mutually perpendicular sides takes place in the exemplary embodiment shown with the aid of a screw 25 which is screwed into a threaded bore 26 parallel to the leg of the corner piece 24 which forms the “slideway”.
  • the threaded bore 26 merges into a thread-free, open half-shell 27.
  • the corner pieces 24 fitted into the frame 7 at the same time absorb the torsional forces acting on the frame sides caused by the one-sided loading of the frame at the ends of the frame sides.
  • the slide bands 8 and 8 ' are arranged at the corners so that, as shown in Fig. 1, the line of action of the tension forces (arrow 28 in Fig. 1) at each corner perpendicular to the plane of the trap the supported side, advantageously through the last detention point 10 '(FIG. 1) of this side and, if possible, in the axis of the detention points 10 of the side perpendicular thereto.
