Definitions

  • Multi-pane insulating glass elements are today standard in building construction for reasons of building insulation. In the simplest form they are designed as a double-pane insulating glass. In order to achieve an even better thermal insulation, they can be filled with a gas which has a lower thermal conductivity than air or are already known multi-pane insulating glass elements with more than two glass panes, for example three. Since the middle pane of glass normally has no static function but merely the function of separating the gap between the outer glass panes, In order to prevent the direct heat conduction from the front to the rear glass pane, multi-pane insulating glass elements have already been proposed in which the middle glass pane is replaced by a plastic film. In addition, this plastic film may also be coated or tinted to reduce the passage of light through the insulating glass element.
  • this describes DE 30 43 973 A1 a method for producing a multi-pane insulating glass unit, which is formed of two by a pair of circumferential spacers spaced and sealed against each other glass sheets and a stretched between the spacers plastic film, wherein the spaces between the discs and the plastic film with each other ,
  • a heat-shrinkable film is used, and after assembly, the insulating glass unit is heated with hot air, so that the film shrinks and becomes taut and wrinkle-free.
  • the plastic film is mechanically stretched during or through the closing (s) of the intermediate space, and characterized in that in the above-mentioned multi-pane insulating glass element, the spacers in the manner of a groove Spring principle are connected to each other and / or that at least one of the spacers comprises a spring element which exerts a compressive force on the plastic film.
  • the advantage here is that is relieved by the mechanical tension of the plastic film during the closing movement of the two Einzelglaselmente the additional process step of the adjoining the marginal composite training process step of thermal stress, so that it can be performed in less time, thereby reducing the cycle time can be reduced. In addition, it is thus possible to reduce the thermal load on the plastic film.
  • the plastic film is tensioned by a tensile stress, which is exerted by means of the spacers by the closing movement on the plastic film.
  • spacers are used, which can be connected to each other according to the tongue and groove principle, or according to a variant embodiment, a spacer is used which has a spring element which exerts a pressure on the plastic film.
  • the plastic film is clamped and fixed between the spacers, so that no additional measures for tensioning the plastic film are required. It can thus be simplified, the clamping device and the cycle time for the production of the multi-pane insulating glass element can be further reduced.
  • the plastic film in the gas filling device is introduced into the intermediate space between the individual glass elements.
  • the incorporation of the plastic film in the gas filling device which is normally present in a production line of a Mehrscheiebn insulating glass production, the integration of the supply of the plastic film is improved in the insulating glass production, whereby cycle times for producing such multi-pane insulating glass elements can be shortened.
  • the edge bond must have no openings for the gas filling of the gap between the glass elements, which on the one hand no subsequent closure of these openings must be done, which ebenfallls the cycle times can be reduced, and on the other hand so that the gas-tightness of the multi-pane insulating glass element can be improved.
  • the plastic film is stretched in the Gasbehell worn.
  • so that a subsequent contamination of the plastic film can be avoided because the multi-pane insulating glass element is still closed under the "clean room conditions" of the gas atmosphere of the filling gas and then an intervention in the space between the individual glass elements of the multi-pane insulating glass element is no longer required.
  • Fig. 1 is a multi-pane insulating glass element 1 shown cut in side view.
  • this multi-pane insulating glass element 1 consists of a first single glass element 2, a second single glass element 3, which is spaced apart to form a gap 4 to the first single glass element 2, a plastic film 5, which is arranged in the intermediate space 4 and this in two subdivided smaller spaces, namely a front space which faces the individual glass element 2, and a rear space which faces the single glass element 3, and an edge seal 6 formed between the two individual glass elements 2, 3 along a circumference 7 of the multi-pane insulating glass element 1 is and a spacer 8, which may optionally have a cavity, wherein the cavity is optionally filled with a molecular sieve 9, and which is connected via a primary sealing element 10 with the two glass elements 2, 3, wherein an additional sealing element 11 at the Rear side of the spacer 8 for sealing the gap between the two individual glass elements 2, 3 may be arranged along the circumference.

In addition, there is also the possibility that more than two individual glass elements 2, 3 are arranged, for example three or four.
  • the thermal conductivity of the multi-pane insulating glass element 1 is to be reduced. Accordingly, a gas is used which is heavier than air, as their mobility is reduced by the heavier gas molecules and thus the thermal conductivity and the heat transfer through the multi-pane insulating glass element 1 is reduced.
  • Useful gases are, for example, argon or xenon, as known in the art.
  • the gap 4 is at least partially filled with this gas.
  • at least partially it is meant that complete filling of the gap 4 with the gas different from air normally does not occur in the insulating glass production due to the long filling times, but a degree of filling of the gap 4 with the gas is at least 90% of the available volume is. Of course, there is the possibility of complete, that is 100% filling of the gap 4 with the gas different from air.

Finally, the two individual glass elements 2, 3 are spent so far relative to each other that the plastic film 5 is clamped between the two part spacers 12, 13 and is formed by pressing the edge seal 6 of the multi-pane insulating glass element 1. In the event that the plastic film 5 is fed in front of the gas filling press 18, there is the possibility that the edge seal 6 is already formed before the gas filling.
