Definitions

  • the invention relates to a spacer for triple insulating glazings, a triple insulating glazing, a process for their preparation and their use.
  • the thermal conductivity of glass is about a factor of 2 to 3 lower than that of concrete or similar building materials.
  • slices are in most cases much thinner than comparable elements made of stone or concrete, buildings often lose the largest proportion of heat through the exterior glazing. This effect is particularly evident in skyscrapers with partial or complete glass facades.
  • the additional costs for heating and air conditioning systems make a not inconsiderable part of the maintenance costs of a building.
  • lower carbon dioxide emissions are required as part of stricter construction regulations.
  • An important solution for this is triple-glazing, which is indispensable in building construction, especially in the context of ever faster rising raw material prices and stricter environmental protection regulations. Triple insulating glazings therefore make up an increasing part of the outwardly facing glazings.
  • Triple insulating glazings typically contain three panes of glass or polymeric materials separated by two individual spacers. The two outer plates are connected via a respective seal with the adjacent spacers, while the middle disc is glued to the spacers.
  • very low tolerance requirements apply because the two spacers must be mounted in exactly the same height.
  • the installation of triple glazing compared to double glazing is much more complex because either additional system components for the installation of another disc must be provided or a time-consuming multiple pass of a classic system is necessary.
  • the thermal insulation capacity of triple insulating glass is significantly increased compared to single or double glazing. With special coatings, such as low-E coatings, this can be further increased and improved. So-called low-E coatings offer an effective way of shielding infrared radiation before entering the living space while allowing daylight to pass through. Low-e coatings are heat-radiation reflective coatings that have a significant impact Part of the infrared radiation reflect, which leads in summer to a reduced warming of the living spaces.
  • the various low-E coatings are known, for example, from DE 10 2009 006 062 A1, WO 2007/101964 A1, EP 0 912 455 B1, DE 199 27 683 C1, EP 1 218 307 B1 and EP 1 917 222 B1.
  • EP 0 852 280 A1 discloses a spacer for double insulating glazings.
  • the spacer comprises a metal foil on the bonding surface and a glass fiber content in the plastic of the base body.
  • Such spacers are also commonly used in triple insulating glazings, with a first spacer mounted between a first outer disk and the inner disk and a second spacer mounted between a second outer disk and the inner disk. The two spacers must be mounted congruent to ensure a visually appealing appearance.
  • a triple insulating glazing with a segment for receiving lines or lighting means is known.
  • the first pane and the second pane of the insulating glass are connected by a spacer, wherein in the space between these two panes, a third disc is arranged, which is connected via a further spacer with the first disc.
  • EP 2 584 135 A2 describes a triple insulating glazing comprising a first and a second glass pane, which are separated by a spacer, wherein a plastic pane is arranged between these two pane.
  • the plastic disk is held by further spacers between the outer glass panes.
  • the spacers of the plastic disc are preferably made of the same material as the plastic disc itself. Since the spacers of the plastic disc are not connected to the spacer between the first and second disc, all three spacers must be positioned independently of each other.
  • the spacer systems known from WO 2012 095 266 A1 and EP 2 584 135 A2 are also expensive to install and require a very precise installation of the individual components.
  • EP 2 270 307 A2 describes a window sash with two outer disks, a middle disk, an edge termination profile and two receiving profiles.
  • the middle disc is inserted, so that in each case a receiving profile between one of the outer discs and the middle disc is located.
  • US Pat. No. 6,1 15,989 discloses a multi-pane insulating glazing in which a central pane is fixed in a U-shaped spacer via a spring profile.
  • Spring profile and spacers are formed in several parts, wherein the spring profile is inserted into the spacer.
  • the object of the present invention is to provide a spacer for triple glazing, which allows a simplified installation of the insulating glazing and can also be used in combination with low-E coatings on the middle pane, and to provide an economical method for mounting a triple glazing with inventive spacer.
  • the triple insulating glazing spacer comprises at least one polymeric base body having a first wafer contact surface and a second disk contact surface extending parallel thereto, a first glazing interior surface, a second glazing interior surface, and an outer surface.
  • a groove for receiving a disc is introduced, which runs parallel to the first disc contact surface and the second disc contact surface.
  • the groove extends between the first glazing interior surface and the second glazing interior surface and separates them from each other.
  • the spring is fixed to the groove facing away from the end of the connected polymeric body, wherein the spring and the polymeric body are integrally formed.
  • the spring is thus designed as a cantilevered spring element.
  • the one-piece design of the spring and the polymeric body is particularly advantageous because these two elements can be made directly in one step and mounted together. An undesirable slippage of the two elements relative to each other is thus not possible.
  • the invention provides a one-piece double spacer ("double spacer") to which all three panes of triple glazing can be fixed, with the two outer panes (first pane and second pane) attached to the pane contact surfaces, while the middle one
  • the spring serves to simplify the assembly of the glazing since the third (middle) pane can be slid into the groove via the spring after attaching one of the outer panes (first or second pane) can be directly on an industrial plant, a preparation of individual components is not necessary.
  • Die spacer according to the invention thereby allows a much more cost-effective and yet accurate installation of triple glazing .
  • the Doppelspacers invention is also a slipping two Einzelspacer, as according to the Stan d the technique used, impossible.
  • the spacer according to the invention has only two disc contact surfaces, the gas loss rate of the insulating glazing relative to a glazing with two individual spacers according to the prior art can be reduced by 50%. Furthermore, error rates due to entry of water across the disc contact surfaces can also be reduced. Furthermore, the fixation according to the invention of the third disc is effected by a groove and not, as known in the prior art, by an adhesive connection. Thus, the spacer according to the invention allows the production of a triple glazing with a low-E coating on the third disc, without biasing the third disc is necessary.
  • the heating of the pane caused by the low-E coating would promote a failure of the adhesive bond.
  • a biasing of the third disc would be necessary to compensate for occurring voltages.
  • the spacer according to the invention eliminates the biasing process, whereby a further cost reduction can be achieved.
  • the tension-free fixing in a groove according to the invention furthermore, the thickness and thus the weight of the third disk can advantageously be reduced.
  • the spring and the polymeric body are coextruded. In this case, the spring and the base body despite one-piece design also consist of different materials.
  • the spring travel of the spring is within a space located between the spring and the underlying glazing interior surface.
  • the spring is elastically deformable in the direction of the glazing interior surface located below it. If the third disc is placed on the glazing interior surface with spring and displaced in the direction of the groove, the spring springs in the direction of the underlying glazing interior surface, so that the disc can be inserted via the spring in the groove. Once the third disc is engaged in the groove no force acts on the spring, which springs back into its original position. In its initial position, the spring forms a side edge of the groove and thus contributes to the fixation of the third disc in the groove.
  • the first disc contact surface and the second disc contact surface represent the sides of the spacer at which the installation of the spacer, the mounting of the outer discs (first disc and second disc) of a glazing is done.
  • the first disc contact surface and the second disc contact surface are parallel to each other.

  • the first glazing interior surface lies between the first and the third pane, while the second glazing interior surface is arranged between the third and the second pane.

  • the outer surface is preferably perpendicular to the disc contact surfaces.
  • the portions of the outer surface closest to the disk contact surfaces are inclined at an angle of preferably 30 ° to 60 ° to the outer surface in the direction of the disk contact surfaces. This angled geometry improves the stability of the polymer body and allows a better bonding of the spacer according to the invention with an insulating film.
  • a planar outer surface that behaves perpendicular to the disk contact surfaces in its entire course, however, has the advantage that the sealing surface between spacers and disc contact surfaces is maximized and easier shaping facilitates the production process.
  • the polymeric base body is designed as a hollow profile, on the one hand a weight reduction compared to a solid-shaped spacer is possible and on the other hand, the cavities for receiving other components, such as a desiccant, are available.
  • the polymeric base body comprises a first hollow chamber and a second hollow chamber, wherein the first hollow chamber is adjacent to the first glazing interior surface and the second hollow chamber is adjacent to the second glazing interior surface.
  • One or both hollow chambers may extend below the groove and form the bottom surface thereof.
  • the formation of two hollow chambers is advantageous over a single hollow chamber which extends over the entire polymeric body, since the partition wall between the two hollow chambers has a positive effect on the stability of the body. If the inter-pane spaces are sealed off from each other in a gas-tight manner, damage to one of the two hollow chambers furthermore only leads to a failure of one pane interspace, while the second pane interspace remains intact.
