Definitions

  • the present invention relates to an insulating glass pane according to the preamble of claim 1.
  • the invention particularly relates to an insulating glass pane consisting of two outer panes, at least one single pane or foil, which is arranged between the two outer panes, and an edge composite which has a spacing profile.
  • the publication US 4,149,348 A relates to an insulating glass pane consisting of two outer plates and two intermediate individual discs and an edge seal with a spacer profile, wherein the spacer profile has two opposite contact surfaces, which with the outer discs on an adhesive layer are connected shear resistant.
  • the inter-pane spaces formed between the individual panes and the two outer panes have a pressure equalization.
  • the two individual discs are held by the spacer profile, which has recesses into which the discs are inserted.
  • An insulating glass pane of the type mentioned is generally known in principle from the prior art. It contains the two outer panes, wherein generally a first outer pane is arranged inside a room, a house, a warehouse or generally a building, and a second outer pane is arranged outside the building. Within the two outer panes, a thermally insulating space is arranged. The advantage lies especially in the larger heat and sound insulation.
  • the insulating glass pane therefore forms today the common way of glazing.
  • the edge seal consists of a hollow profile made of metal or plastic, in which a desiccant for the function of drying the trapped air in the space of the insulating glass is housed. To the outside, an additional seal made of silicone or polysulfide is attached.
  • the marginal composite does not assume any static function.
  • the insulating glass pane behaves statically more or less like two outer panes.
  • the previous spacers, as well as the previous sealing materials, are not able to connect the two outer sheaves so far shear-resistant, that the two outer plates can be worn without visible support profiles.
  • the present invention seeks to further develop an insulating glass pane of the type mentioned in that the insulating glass has a self-supporting structure, so that dispensed visible support profiles for supporting the insulating glass or these can be at least significantly reduced.
  • the invention proposes that at least one of the two disc spaces formed between the single pane or film and the two outer panes is connected by printing technology to the atmosphere. This is achieved by at least one of the disc spaces having a pressure equalization.
  • An equal pressure in the space between the panes advantageously means that no angle changes and thus no tensile stresses in the region of the bonds at the edge bond occur.
  • the single disc or foil is made relatively thin and may bulge inward or outward when pressure changes. Due to the pressure, the inner single disc bulges in the direction of a space between the panes. The thinner the single pane, the more it can bulge out. As a result, there is only a slight pressure increase in the space between the panes.
  • the pressure equalization takes place via an opening or via a pressure equalization tube, which connects the at least one space between the panes with the atmosphere.
  • the pressure compensation via the Atmosphere of the outside air, as it is usually drier than heated indoor air.
  • outside air here is meant the air outside the building.
  • an inner space between the panes, which is aligned with the interior, is connected to the atmosphere of the outside air, and an outer space between the panes, which is aligned with the outside air, is hermetically sealed.
  • the pressure increases, as a result of which the inner intermediate pane bulges out in the direction of the inner space between the panes.
  • only a slight pressure increase occurs in the outer space between the panes.
  • the volume of the outer pane space is smaller than the volume of the inner pane space.
  • the pressure increase is further reduced.
  • any volume changes and temperature changes in the inner space between the panes will result in no or only slight pressure changes.
  • the spacer profile consists of a high-strength plastic material, in particular of a glass fiber reinforced plastic.
  • a material is used which has a relatively low thermal conductivity and still has high strengths in an advantageous manner.
  • Another advantage lies in the thermal expansion coefficient, which is very similar between glass and glass fiber reinforced plastic. This is important because there are no additional forces due to different elongation.
  • the connection of the spacer profile can be done either by appropriately high-strength adhesive or by high-strength composite films.
  • the high-strength adhesive or the high-strength composite film may for example consist of a polymer, for. As polyvinyl butyral, ionoplast (polymer), semi-crystalline thermoplastic or other material, which has the required adhesive strength, durability and thermal stability.
  • a viscoelastic, two-component adhesive based on epoxy resin is used.
  • Such adhesives have a tensile shear strength of at least 10 / mm 2 compared to the adhesive surfaces and its modulus of elasticity under short-term loading is greater than 1000 N / mm 2 .
  • the spacer profile has two opposite contact surfaces, which are made relatively uniformly thick, in order to produce a uniform voltage curve in the adhesive layer there.
  • the spacing profile may also be designed such that one or more drying agents, for example in one or more cavities of the profile, are integrated.
  • each of the desiccants can also be accommodated in an additional desiccant profile. But it can also be installed commercially available spacer profiles with desiccant.
  • an additional profile is attached as an intermediate layer between the contact surfaces of the spacer profile and the outer panes with the aid of a transparent adhesive or a transparent film on at least one of the two outer panes.
  • FIG. 1 shows a cross-sectional view of the edge region of a not claimed as invention insulating glass pane 1, wherein an inner space between the panes 26 has a pressure equalization and a single disc 22 between two profile parts 5a, 5b of a spacer profile 5 is maintained.
  • the insulating glass pane 1 contains at least two outer panes 2, 3 and an edge composite 4, which has the spacing profile 5, which consists in this embodiment of two profile parts 5a, 5b.
  • the spacer profile 5 consists of a high-strength plastic and has two opposite contact surfaces 12. The two contact surfaces 12 are connected shear-resistant with the respective inner sides of the two outer disks 2, 3.
  • an adhesive layer 11 which provides this shear-resistant composite between the spacer profile 5 and the outer panes 2, 3. Since the single disc or foil 22 is arranged here between the two outer panes 2, 3, this construction forms an inner pan space 26, which is oriented towards the inner space, and an outer pan space 25, which is oriented toward the outside air. The inner space between the panes 26 has a pressure equalization, which takes place via a pressure equalizing tube 27, which connects the inner pane space 26 with the atmosphere of the outside air. The outer space between the panes 25 is hermetically sealed. In this embodiment, the single disc or foil 22 is held by the two profile parts 5a, 5b.
  • each one seal is provided.
  • the volume of the outer space between the panes 25 is preferably smaller than the volume of the inner space between the panes. As a result, only a slight increase in pressure occurs in the outer pan space 25.
  • FIG. 2 shows an embodiment of the invention, wherein the single disc or foil 22 is held here by two retaining profiles 9, which are respectively clamped between the single disc or foil 22 and the outer discs 2, 3. At the contact points between the single disc or foil 22 and the holding profiles 9 and between the outer plates 2, 3 and the holding profiles 9, a seal is provided in each case.
  • the spacer profile 5 is integrally formed.
  • the space between the panes is deliberately hermetically sealed.
  • the air or the gas in the space between the panes is kept as dry as possible by special desiccant 10. This is necessary so that when the temperature changes, especially when the outer pane cools to the outside, no condensation takes place on the inside.
  • the desiccant 10 is contained in the holding profiles 9.
  • the following describes the operation of the pressure equalization. Specifically, it is provided in these embodiments to reduce the stresses on the adhesive layer 11 between the contact surfaces 12 and the outer panes 2, 3 due to the climatic loads by opening the inner pane clearance 26 to the outside, thereby allowing pressure equalization.
  • Constant pressure in the space between the panes 26 means that no angle changes occur in the area of the adhesive layer 11.
  • the opening of the space between the panes of an insulating glass unit contradicts the previous insulating glass technique.
  • the insulating glass pane 1 is designed as a triple disc.
  • the insulating glass has two disc spaces 25, 26.
  • the two disc spaces 25, 26 are separated by a thin single disc 22 or by a thin transparent film 22.
  • the outer space between the panes 25 is hermetically sealed as in a normal insulating glass pane. This disc space 25 is also kept relatively small.
  • the inner space between the panes 26 is connected to the outside air by one or more pressure equalizing tubes 27, preferably capillary tubes.
  • the outside air is usually always drier than heated room air.
  • the pressure increases here. Due to the pressure, the inner single disc 22 bulges in the direction of the inner space between the panes. The thinner the individual disk 22, the more the individual disk 22 can bulge. As a result, only a slight increase in pressure occurs in the outer pane space 25.
  • the pressure increase is also further reduced as a result.
  • the inner space between the panes 26 is connected by pressure to the outside air. This means that any volume changes and temperature changes in the inner space between the panes 26 result in no or only slight pressure changes.
  • the Pressure connection of the inner space between the panes 26 should only be made to the outside air.
  • moisture is also forced to be registered. Part of the moisture is absorbed by the desiccant 10. When the desiccant 10 is saturated, the moisture is absorbed by the air present in the space between the panes 25, 26. Due to the previously described embodiment, there is no risk of condensation.
  • the outside air entering the space between the panes of the outside atmosphere 26 is usually drier than the room air.
  • the outside air when it enters the space between the panes 26, is heated therein. Heating reduces the relative humidity of this air.
  • the adjoining the inner space between the panes 26 glass walls are relatively warm, as they connect directly to the interior, or isolated by the outer pane space 25 from the outside. In this respect, there is no risk of condensate formation even in the presence of moisture in the inner space between the panes.
  • additional profiles 19 can be inserted between the spacer profile 5, or between the profile parts 5a, 5b (not shown), and the outer plates 2, 3 for reasons of appearance. This is the case when working with transparent adhesives and the outer disks 2, 3 in the region of the edge composite 4 have no printing.
  • the visible region of the edge bond 4 could also be made in different colors or structures. This is done as follows:
  • the additional flat profile 19 is glued by means of a transparent adhesive 20.
  • the profile 19 can be executed with one or more folds be. As a result, the appearance and the handling of the profile 19 are improved.
  • the profile 19 can be made of different materials or it can be made in any imaginable color. Through the transparent adhesive 20, the material or its color through the outer plates 2, 3 is visible.
  • the transparent adhesive 20 of the additional profile 19 on the outer panes 2, 3 can be designed as a transparent UV or two-component adhesive.
  • the thickness of the additional profile 19 is chosen as a function of the material used so that the stresses occurring due to different thermal expansion are as small as possible and can be absorbed by the bond.
  • An insulating glass pane 1b has two outer panes 2, 3, wherein in one of the two outer panes 2, 3 limited space at least one further disc or a film 22, 32, for forming a first and second space between the panes 30, 31 is arranged.
  • the further disc or film 22, 32 is at least partially flexible.
  • a spacing profile 5, which is arranged between the two outer panes 2, 3, has a first region 26 and a second region 27, which are connected to one another in regions in a shear-resistant manner or connected.
  • the first region 26 and the second region 27 of the spacer profile 5 are each designed as spacer profile elements with an L-shaped cross-sectional geometry.
  • Each of the spacer profile elements has two legs 26a, 26b; 27a, 27b.
  • an articulated region 13 is formed in each case.
  • a first leg 26a, 27a of each region 26, 27 runs parallel to one of the two outer disks 2, 3 and is connected to the outer disk 2, 3 in a shear-resistant manner.
  • a second leg 26b of the one region 26 runs parallel to a second leg 27b of the other region 27 and is connected thereto at least in one region 28.
  • a pressure compensation is provided at least for one of the two disc spaces 30, 31, wherein at least one pressure equalization tube 29, in particular capillary tube is provided, and / or wherein at least one membrane, in particular an air-permeable but not water-permeable membrane, is provided in a channel 29 to Purposes of a Pressure equalization joins a disc space with the outside atmosphere.
  • one or more desiccants 10 may be integrated into one or more cavities in the inter-disc spaces 30, 31 and held over adhesive dots 33.
