Definitions

  • the invention relates to a Mehrularnisolierglas, in particular three-disc insulating glass, having a first, a second and a third glass pane, wherein the first and the second glass sheet and the second and the third glass are each spaced by a gap, wherein the space between the first and the second glass is hermetically sealed.
  • Multi-pane insulating glasses are also referred to as insulating glazing or insulating glazing.
  • a generic multi-pane insulating glass is a component composed of at least three glass panes for windows and other glazings. The spaces between the glass panes are used for thermal insulation, since the gases to be introduced into a gap have a lower thermal conductivity than the panes themselves:
  • the deformation of the glass panes leads, for example, to distorted mirror images, for example in the case of a large glass façade of a building. This effect is undesirable.
  • the object of the present invention to prevent a deterioration of the aesthetics by deformation of the glass panes in a generic multi-pane insulating glass at the same time good thermal insulation and also to increase the life of the multi-pane insulating glass, and to reduce the total weight of the pane by reducing the thicknesses.
  • the second glass pane has a lower bending stiffness than the first glass pane and the space between the second and the third glass pane for pressure equalization is fluidly connected to the environment of the multi-pane insulating glass.
  • the second glass pane with both the first and the third glass pane each defines a gap, this is a medium glass.
  • This second pane of glass is consequently enclosed between the first and the third pane of glass.
  • This second glass pane according to the invention is less resistant to bending than the first glass pane. It may also have a lower flexural rigidity than the third glass sheet. This has the effect that, after a pressure and / or temperature change, the gas trapped in the space between the first and the second glass pane changes in volume, but this volume change in particular leads exclusively to a deformation of the second glass pane. Due to the lower flexural rigidity, a lower force than the first glass pane is sufficient to cause deformation.
  • the first glass sheet retains its original shape even under pressure and / or temperature variations. Since the first glass sheet is an outer glass sheet, there is no distortion of a mirror image and / or the like. This creates an optimized aesthetic impression.
  • the core idea of the invention consists in the fact that the other intermediate space between the second and the third glass pane is just not hermetically sealed. This means that this space for pressure equalization is fluidically connected to the environment of the multi-pane insulating glass. A deformation of the second glass pane thus does not lead to an increase in pressure on the third glass pane, that this would also deform. The resulting pressure changes are compensated by the pressure equalization with the environment. This means that in the case of a volume expansion in the space between the first and the second glass pane, the second glass pane bulges in the direction of the third glass pane and air present in the intermediate space between the second and the third glass pane is pressed out of the multi-pane insulating glass.
  • the outer glass panes that is to say in the case of three panes of glass, the first and the third pane retain their shape independently of the ambient conditions.
  • the otherwise usual with hermetically sealed Mehrusionnisoliergläsern deformations and resulting aesthetic distortions can be largely avoided.
  • a multi-pane insulating glass according to the invention nevertheless makes it possible to hermetically seal at least one intermediate space between two glass panes.
  • the advantage can be achieved that virtually no heat transfer by convection takes place in this intermediate space and, in addition, any gases can be used which have better thermal insulation properties than the ambient air.
  • the multi-pane insulating glass has a comparatively long service life, since as a result of the prevention of permanent deformation of the first and third glass panes, the gaskets tire less quickly and thus last longer.
  • a lower flexural rigidity can be achieved for example by an alternative material for the glass pane.
  • the second glass pane is thinner than the first glass pane (and possibly also as the third glass pane).
  • the flexural rigidity of a glass sheet is determined by its thickness.
  • the second glass pane advantageously one and the same material can be used for all three glass panes. This may be advantageous in terms of optical properties of the multi-pane insulating glass.
  • the second glass pane can be between 1.5 mm and 2.5 mm, in particular 2 mm thick.
  • the first glass pane and, if necessary, also the third glass pane can be between 3 mm and 8 mm, in particular 4 mm and 6 mm thick.
  • the invention relates in particular to glass panes which are formed incompressible.
  • the glass sheets may be spaced apart by frames. Depending on the thickness of the frame, the thickness of the gap can be selected. The spaces can be arbitrarily large, especially between 12 mm and 16 mm thick.
  • the frame may be formed in one piece or from individual profile elements.
  • a desiccant is incorporated to absorb moisture.
  • This may be a silica gel or molecular sieve and / or the like.
  • the hermetically sealed space spanning frame may have openings on its inner surface. These can be distributed over the entire inner surface. Through these openings, the gas contained in the intermediate space can come into contact with the drying agent arranged in the frame. In this way, if necessary. Nevertheless occurring moisture levels can be kept out of the gap.
  • the frame between the second and the third glass provides a compensation volume. By means of this compensation volume, an overpressure or a negative pressure in the second intermediate space and thus also a deformation of the third glass pane can be prevented.
  • a drying agent may also be arranged.
  • the frame preferably has a first opening for fluidic communication with the intermediate space and a second opening for fluidic communication with the environment of the multi-pane insulating glass.
  • the frame preferably does not have a plurality of openings, but only the first and second openings.
  • the frame may be formed as a flow-closed channel.
  • the two openings of the frame are preferably at a maximum distance from each other.
  • the desiccants can be provided, so that it can be ensured as far as possible that as little moisture as possible can penetrate into the intermediate space.
  • a switch may be arranged.
  • This may have an inlet and outlet opening.
  • the cross-sectional geometry of this opening determines the pressure compensation behavior.
  • the cross-sectional area, the cross-sectional shape and / or the like can be chosen as desired become. As a result, it can be set, for example, that an air exchange between the intermediate space and the environment takes place only comparatively slowly.
  • a multi-pane insulating glass according to the invention is in particular a monolithic composite which can be handled as a unit. All glass panels are interconnected. So it is not just an arrangement in which individual glass panes are handled separately and placed against each other on the user side.
  • the hermetically sealed gap between the first and the second glass pane is filled with argon or krypton.
  • gases have a particularly low thermal conductivity.
  • heat transfer by conduction and convection can be effectively reduced by the use of these gases.
  • Fig. 3a an embodiment with a drying cartridge.
  • Fig. 1 shows an embodiment of a multi-pane insulating glass according to the invention. This is in the present case designed as Dreiuernisolierglas 1.
  • the first glass sheet 2 and the third glass sheet 4 constitute the outer glass sheets of the three-disc insulating glass 1.
  • the second glass sheet 3 is a medium glass pane.
  • the second glass pane 3 has a lower bending stiffness than the first glass pane 2 and the third glass pane 4. This can - and is in the present embodiment - achieved in that the second glass pane 3 has a smaller thickness 10 than the first glass pane 2 and the third glass pane 4. The thicknesses 9, 11 of these glass panes are therefore greater than the thickness 10 of the second pane of glass 3.
  • first intermediate space 5 is formed between the first glass pane 2 and the second glass pane 3. Between the second glass pane 3 and the third glass pane 4, a second intermediate space 6 is formed.
  • the first gap 5 is hermetically sealed.
  • a circumferential seal 7 is used.
  • the seal 7 may be formed, for example, from polysulfite or the like.
  • a frame 13 is arranged within the hermetically sealed first gap 5. This can consist of individual profile elements 12.
  • a desiccant 17 is arranged in the frame. This may be silica gel or molecular sieve.
  • the left frame of the first gap 5 is characterized in that it is porous on its inside. It has a multiplicity of openings through which the gas located in the first intermediate space 5 can come into contact with the desiccant 17. As a result, any existing moisture within the gap 5 can be effectively tied.
  • the second gap 6 between the second and the third glass pane 3, 4, however, is not hermetically sealed. Although it is also a seal 8 is provided. However, this has an opening 15 through which communicates with the environment of Dreiignenisolierglases 1 fluidically.
  • a frame 13 is also arranged. This can be formed from profile elements or as a circumferential frame.
  • a desiccant 17 is also provided.
  • the frame in the second space 6 is not formed porous. He only has two openings. A first opening serves to communicate via the opening 15 in the seal 8 with the environment fluidly. A second opening 16 follows from the illustration Fig. 3 out. This is spaced in the circumferential direction of the frame 13 from the first opening 15. A direct fluidic connection between the first opening 15 and the second opening 16 is prevented by a web 18.
  • gas that wants to flow between the vicinity of the three-disc insulating glass 1 and the second gap 6 must pass a flow passage 14. This extends around the entire circumference of the frame thirteenth
  • desiccant 17 is arranged in the frame 13 desiccant 17 . If the gas flows along the flow channel 14, it comes necessarily with the desiccant 17 in contact. As a result, moisture contained in the gas can be bound particularly effectively and dirt particles can be retained.
  • the advantages of the invention will now be as follows.
  • the first gap 5 is hermetically sealed.
  • 5 other gases than in the environment can be used in this space, for example, argon or krypton.
  • This makes it possible to achieve particularly good thermal conduction properties with regard to thermal insulation.
  • the volume of the gas in the first intermediate space 5 increases, for example, this leads according to the invention only to a deformation of the middle second glass pane 3. This is because it has a lower flexural rigidity than the first glass pane 2. Consequently, the aesthetic appearance of the three-disc insulating glass 1 is not impaired from the outside. In particular, distorted mirror images due to deformation of the first glass pane 2 and / or the like do not occur.
  • the second glass sheet 3 serves as a kind of pump. Depending on the ambient conditions, it pumps or sucks air from the second interspace 6 into the environment or from the environment into the second Interspace 6. However, moisture does not enter the second interspace 6 for a comparatively long time since the air has to pass through the comparatively long flow channel 14 with the desiccant 17. Incipient moisture can be effectively bound therein.
  • the invention thus provides a multi-pane insulating glass which, due to the hermetically sealed gap 5, has very good thermal insulation properties but at the same time satisfies the highest aesthetic requirements and practically no deformations of the outer first and third glass panes 2, 4 occur during operation.
  • This synergistically means that the Dreiinisolierglas 1 less fatigued less quickly, that is, for example, the seals 7, 8 hold very long.
  • it could be provided to put on the opening 15, a cartridge 19 with desiccant 17, which can be replaced by consumption.
  • the drying cartridge 19 communicates with the opening 15 of the second space 6 and has an opening 20 to the environment. This is in Fig. 3a shown. Blindness of the three-disc insulating glass 1 can thereby be delayed or prevented.
  • the life of the Dreiidenisolierglases 1 according to the invention could then be extended almost arbitrarily.
