Description

Modular system for multiple insulating glazing, multiple insulating glazing and method of manufacturing multiple insulating glazing

The invention relates to a modular system for a Mehrfachisolierverglasung, a

Multiple insulation glazing and a process for producing the multiple insulation glazing. The modular system is suitable for two or more components

To provide multiple insulation glazing. The thermal conductivity of glass is about a factor of 2 to 3 lower than that of concrete or similar building materials. However, since glass panels are in most cases designed to be significantly thinner than comparable elements made of stone or concrete, buildings often lose the largest proportion of heat via exterior glazing. This effect is particularly evident in skyscrapers with very large or complete glass facades in relation to the façade surface. The necessary additional costs for heating and air conditioning systems make up a not inconsiderable part of the operating costs of a building. In addition, lower carbon dioxide emissions are required as part of stricter construction regulations. In the window and facade area of buildings nowadays almost exclusively insulating glazings are used.

Doppelisolierverglasungen usually consist of two disc elements, which are arranged by a spacer (spacer) at a defined distance from each other. The thermal insulation capacity of triple insulating glazings is still increased compared to single or double glazing. To produce a triple insulating glazing, for example, a second pane can be placed on a double glazing by means of an additional fastening means. Such a triple glazing is in the

EP0922828A2. The glazing has a double-glazing component with a first pane element with a first pane sealing surface, a second pane element

Disc member with a second disc sealing surface, one between the first

Spacer disposed spacer disc and the second disc sealing surface constructed of at least two spacer struts, which encompass between the first disc member and the second disc member an insulating glass volume and gas-tight by means of fixing the first disc sealing surface and the second

Disc sealing surface are fixed. This double glazing is used in a sash, on which a third disc element is detachably arranged. The production of such triple glazing is compared to the industrial one

Manufacture of double glazing significantly more complex because either additional system components for the installation of another disc must be provided or a time-consuming multiple pass through a classic system is necessary.

Furthermore, CA 2 876 598 A1 describes a multiple glazing which has a double glazing whose glass panes are spaced apart by a spacer having a recess into which a stained glass is inserted in order

To provide jewelry windows.

Furthermore, triple insulating glazings are known from US 2001/001357 A1, which have a first disk element and second disk element, between which a one-piece spacer is arranged, which accommodates a third disk element between the first disk element and the second disk element in an insert. To produce such a multiple insulating glazing, the one-piece spacer is first arranged around outer edges of the third pane element. For this purpose, the spacer is folded at kinks, at the corners of the third

Disc element come to rest. Finally, a connecting means serves to close the frame formed by the spacer. In subsequent process steps, the first slide element and the second plate element are glued parallel to the third plate element with opposite outer edges of the spacer to obtain a Mehrfachierierglglasung in the form of a triple glazing.

Object of the present invention is a modular system for a

To provide Mehrfachisolierverglasung that allows a much simplified production of a Mehrfachisolierverglasung and is inexpensive. Further, it is an object to provide the multiple-insulation glazing and a method of manufacturing the same, which are inexpensive. The object of the present invention is achieved by a modular system, a Mehrfachisolierverglasung and a method for producing the

Multiple insulating glazing according to claims 1, 14 and 15 solved. preferred

Embodiments of the invention will become apparent from the dependent claims.

The invention relates to a modular system for a Mehrfachisolierverglasung comprising - a double glazing component with

A first disk element having a first disk sealing surface, A second disk element having a second disk sealing surface,

A spacer disposed between the first disk sealing surface and the second disk sealing surface, constructed of at least one spacer strut disposed between the first disk member and the second disk

Disk element surrounds an insulating glass volume and is gas-tight fixed by means of fixation on the first disk sealing surface and the second disk sealing surface, wherein the at least one spacer strut is designed and arranged as a partially open frame, so that between two spacer struts a receiving opening is formed, the so is dimensioned such that through this a third disc element in the insulating glass volume of the

Double glazing component,

- A closure member with the third disc element

and

- A closure sealant for gas-tight sealing of the insulating glass volume through the closure member after placing the closure member at the receiving opening.

This modular system allows a simple installation of a Mehrfachisolierverglasung particular triple insulation glazing in that the third disc element can be inserted into the double glazing component by inserting. Another advantage here is that the multiple insulating glazing can be easily varied by the third disc element is selected from a variety of possible disc elements according to desired requirements by the user or buyer of the modular system. The structure of the modular system is particularly advantageous if the third disc element is a sensitive component of the insulating glazing, which must first be pre-assembled and tested for its functionality before it is placed in its final mounting position in the insulating glass. This is especially true for third disc elements in the form of so-called functional, often electrically driven glass panes or disc-shaped electrical display elements. Such third disc elements are sometimes highly sensitive and very expensive. They must be electrically contacted inside the insulating glass volume and be permanently fully functional. In a classical manufacturing process for a triple glazing, first the multiple insulating glazing would consist of the three pane elements and two

Spacer system assembled and hermetically connected. This process is associated with a plurality of processing steps. If, after the production of the hermetically sealed insulating glazing, it is determined that the sensitive third pane element processed as an inner pane is not or not fully functional, the entire glazing must be sorted out as scrap. In contrast, the inventive modular system allows a separate, preliminary pre-assembly of the third disc element, without being exposed to the processing steps for producing the double glazing component. The pre-assembled third

Disc element may be prior to insertion into the insulating glass volume of

Double glazing components are fully tested for its functionality. Only then are the third pane member and the double glazing member "married" to a multiple insulating glazing, thus substantially reducing the amount of broke in the manufacture of multiple insulating glazings, particularly in the form of triple glazing with a functional inner pane.

If the insertion of the third disc element is made reversible, the modular system allows easy replacement of the third disc element, if this is indicated during maintenance or conversion.

The expression that the spacer struts are formed as sections "open frame" denotes a frame structure, in which along a frame portion, for example along one of its edges, a receiving opening in this

Frame section is arranged. Likewise, this feature is realized when the

Receiving opening is given by the partially complete absence of a spacer strut. Even then, between two spacer struts one

Receiving opening formed. A spacer strut is in the context of the invention, a straight striving-like element which spaces the first and second disc element.

As materials for the first disk element and the second disk element, which are preferably transparent and / or translucent, are, for example, materials from the group consisting of colored and uncolored glasses, colored and uncolored, rigid, clear plastics, with a barrier to vapor diffusion are selected. However, colored and uncolored glasses are preferably selected.

Preferably, the colored and uncolored glass is selected from the group consisting of colored and undyed, non-tempered, semi-tempered and tempered float glass, cast glass, ceramic glass and glass. Float glass is particularly preferred. The first and second disk sealing surfaces are surfaces of the first and second

Disc element, with the formation of a sealing boundary layer with the

Spacers are connected via the fixing means. The spacer is constructed of spacer struts which surround an insulating glass volume between the first disk element and the second disk element. The encompassing feature includes the geometry that the frame formed from the spacer struts is not completely closed, but is partially interrupted by the complete absence of a spacer strut.

The fixing fix the spacer struts gas-tight at the first

Disc sealing surface and at the second disc sealing surface. The fixing means are preferably sealing means, for example butyl (polyisobutylene / PIB), which hermetically seal a gap between the spacer struts and the disc sealing surfaces.

The first and second disc elements are preferably rectangular, so that they each have four disc edges. The spacer is adapted to the shape of the disc elements along their disc edges. The open frame formed from the at least one spacer strut is preferably substantially U-shaped along three pulley edges or rectangular along all four pulley edges in a rectangular geometry of the pulley elements along the pulley edges

educated. When only a single spacer strut is provided, it integrally usually follows the course of the edges of the first and second disc elements. In the case of a U-shaped or rectangular formation of the extension of the

Spacer, the spacer may have an integrally formed spacer strut, which is shaped according to this course. Alternatively, preferably, the spacer has a plurality of, in particular along the disc edges of rectangular disc elements three or four spacer struts, which are joined together, for example glued or welded or connected via corner connectors.

Preferably, ends of the spacer struts forming the corners of the spacer are either welded or linked together by corner joints. Preferably, the spacer has a single receiving opening for the third

Disc element on. However, it is also possible that a plurality of

Receiving openings is provided. With regard to its dimensioning, the third disk element does not have to be adapted to the outer disks provided as the first and second disk element in order to form a triple glazing as a whole.

It is also conceivable that the third disc element occupies only a portion of the surface of the outer pane, which occupies less than two thirds or half of the surface of the outer panes and, for example, only a quarter of the outer pane surface occupies. In particular, if the third disc element is designed as an electrical display, which should not assume the transparency of the entire double glazing component. Preferably, at least one of the spacer struts is designed as a receiving strut and has the receiving opening. In this case, the open frame formed by the spacer is preferably rectangular and preferably has four spacer struts, one of which is designed as a receiving strut. But it can also be provided with a plurality of receiving openings more spacer struts. The

Receiving aperture is formed in the receiving strut so as to extend between two spacer struts adjacent the receiving strut, the two adjacent spacer struts extending perpendicularly or substantially perpendicularly to the receiving strut. In a one-piece design of the spacer strut this is formed along a portion having a receiving opening and thus

partially formed in the form of a receiving strut.

Preferably, the receiving strut surrounds the receiving opening on all sides. That is, the receiving opening is formed as an elongated slot in the receiving strut. However, it is still arranged between two spacer struts, since the receiving strut is arranged between two spacer struts adjacent thereto. The length of the slot formed as a receiving opening can occupy almost the entire recording strut. This is especially the case when the modular system is to be used to realize a Mehrfachisolierverglasung, preferably a triple insulating glazing.

In all variants of the modular system described above, preferably adjacent to the receiving strut or to the receiving opening on the first disk element, a first sealing section and on the second disk element a second sealing section are exposed. The sealing portions may in particular for the arrangement of the closure component and the closure sealant between the respective

Be formed sealing portion and the closure member suitable. The closure sealant is preferably designed to be circumferentially arranged around the receiving opening, so that after joining the components of the modular system between the closure member, the receiving strut and / or spacer struts the first

Sealing portion and the second sealing portion is arranged. Structurally, for this purpose, the closure sealant on the closure component and / or on the first and second

Sealing section and connecting to these two sealing sections Querdicht sections be fixed. The first and second sealing portions and the transverse sealing portions together enclose the receiving opening to a gas-tight connection of the closure member with the double-glazing component. Preferably, the first sealing portion is disposed on the first disk sealing surface and the second sealing portion is disposed on the second disk sealing surface. The arranged between the first disk sealing surface and the second disk sealing surface

Shooting strut of the spacer closes in this embodiment with the

The edges of the outer panes are not flush. Rather, the spacer is arranged such that the disc elements have surfaces lying outside the insulating glass volume, which form the sealing portions on the disc sealing surfaces.

In a preferred embodiment, the spacer struts are moisture-proof in relation to moisture penetrating from the outside but are formed without a desiccant. They do not contain a desiccant to the insulating glass volume acting desiccant. In this

Embodiment serve the spacer struts therefore for the production

Insulating glass volume in double glazing element, to ward off the effects of weather such as moisture and have sufficient for the Mehrfachisolierverglasung thermal insulation between the first disc element and the second disc element. Because no desiccant is provided in the structure of the spacer, the spacers can be made particularly slim. The functionality of the drying agent is introduced into the insulating glass volume of the double glazing component together with the third pane element. The following describes how the

Wheel edges of the third disc element are surrounded by a further spacer which is inserted into the insulating glass volume.

In an alternative preferred embodiment, the spacer struts are moisture-proof against moisture penetrating from the outside and at least partially contain a desiccant volume acting towards the insulating glass volume. The spacer struts in this embodiment form a spacer, which preferably comprises a hollow base body with at least two parallel disc contact legs, an outer leg, two glazing inner leg and a groove, so that a first cavity and a second cavity are formed separated by the groove. In the cavities preferably at least partially a desiccant is arranged. The hollow body extends between the first disk element and the second disk element. While the one

Disk contact leg on the first disk sealing surface of the first disk element is fixed, the further disk contact leg is fixed to the second disk sealing surface of the second disk element. Limit the glazed interior legs

together with the first disc element and the second disc element, the insulating glass volume. The groove serves to receive the third disc element.

As a hollow base body, all known from the prior art hollow body profiles regardless of their material composition can be used.

By way of example, mention may be made here of polymeric or metallic materials for spacer struts, regardless of whether they are in the form of a hollow base body or a plate or plate

Disk body are formed or not.

Polymeric materials for spacer struts preferably comprise polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylate, polyacrylates, polyamides, polyethylene terephthalate

(PET), polybutylene terephthalate (PBT), more preferably acrylonitrile-butadiene-styrene (ABS), acrylic ester-styrene-acrylonitrile (ASA), acrylonitrile-butadiene-styrene / polycarbonate (ABS / PC), styrene-acrylonitrile (SAN), PET / PC, PBT / PC and / or copolymers or mixtures thereof. The polymeric material may optionally also contain other ingredients such as glass fibers and / or glass bubbles. For example, the polymeric base body is glass fiber reinforced. By choosing the glass fiber content in the body of the

Thermal expansion coefficient of the body varies and adjusted. The hollow body preferably has a glass fiber content of 20% to 50%, particularly preferably from 30% to 40%. The glass fiber content in the polymer base body simultaneously improves the strength and stability and may be partially substituted by glass bubbles to increase the thermal insulation.

The polymeric materials used are usually gas-permeable, so that if this permeability is not desirable, further measures must be taken.

For example, a gas-tight or gas-impermeable insulation film or corresponding coatings are arranged for the gas-tight embodiment of the polymeric material or in the case of a hollow base body in particular on its outer leg.

Metallic spacer struts are preferably made of aluminum or stainless steel and thus naturally have no gas permeability. In another preferred embodiment, however, the base body is gas-permeable to the insulating glass volume, wherein a permeability can be achieved, for example, by introducing openings into the base body. Especially in metallic hollow desiccant filled bodies whose walls are not gas-permeable, openings are introduced where necessary to achieve the necessary gas permeability. For example, in order to produce a permeable region in the glazing interior legs of the hollow base body, openings of the required number and size are introduced into this region of the glazing interior limb. The total number of openings depends on the size of the

Modular system. The openings connect the hollow chamber of the hollow body with the insulating glass volume of the modular system, whereby a gas exchange between them even after insertion of the third disc member and separating the

Insulating glass volume of the environment is possible. The openings are preferably designed such that the desiccant disposed in the hollow chamber can not get into the inner space between the panes. The openings are preferably designed as slots, particularly preferably as slots with a width of 0.2 mm and a length of 2 mm.

Preferred drying agents are silica gel, CaCl ₂ , Na ₂ SO ₄ , activated carbon, silicates, bentonites, zeolites and / or mixtures thereof, more preferably molecular sieves. This

Desiccant is preferably introduced into the hollow chamber of the body.

The modular system has, in addition to the double glazing component, the closure component with the third pane element which can be inserted into the double glazing component and

Closure sealant for gas-tight sealing of the insulating glass volume by the

Closing member after arranging the closure member at the receiving opening. The double glazing component, the closure component and the closure sealant are components of a modular system. By inserting and sealing the sealing member into and with the double-glazing member using the closure sealant, the gas-tight multiple-insulation glazing is obtained. If the modular system has the double-glazing member, the closure member and the closure sealant in the assembled state, then the

Multiple insulation glazing finished. In contrast, this indicates

Modular system, the double glazing component, the closure member and the closure sealant in the separated state, so that the components to the

Join multiple insulation glazing together. Furthermore, the modular system can have two separate components, namely the double-glass component with closure element arranged thereon. Have sealing means and the closure member, wherein the closure sealing means is preferably arranged circumferentially around the receiving opening. As a further variant, the modular system may have the double-glazed component as a component and the closure component with closure-sealing means arranged thereon as another component. As an additional variant, it is also possible to fix the closure sealant in sections on the double-glazing component and on the closure component prior to assembly of the component.

As a material for the third disc member, which is preferably transparent, is

For example, a material from the group consisting of colored and uncolored

Glasses, colored and uncolored, rigid, clear plastics provided with a vapor diffusion barrier. Preferably, however, a colored or uncolored glass is selected. Preferably, the colored and uncolored glass is selected from the group consisting of colored and undyed, unbiased,

semi-tempered and toughened float glass, cast glass, ceramic glass and glass. Float glass is particularly preferred.

Preferably, the third disc element has a slightly smaller extent than the first and second disc element, so that the situation of a triple glazing is made. If the third disc element is designed as a functional glass, it is possible for a large extent of the first and the second disc element, that the third disc element is formed of a plurality of juxtaposed sub-disc elements. Sub-disk elements can be joined and fixed to one another, for example, by means of a holding means, which engage around the sub-disk elements at respectively one of their inner edges.

As already stated, a further subgroup of preferred embodiments of the modular system is characterized in that the third disc element is designed as a so-called functional glass. It is also conceivable to form the third disc element as an electrically controllable display. The achievable by the modular system advantages in the processing of such sensitive and expensive inner panes have already been described above.

An outer edge of the third disc member constitutes an edge facing towards the lid member or the spacer strut of the double glass member when the third disc member is disposed in the double glass member or also exposed when the third disc member is not disposed in the double glass member , An inner edge of the third disc element represents an edge, which is adjacent to an edge of a sub-disc element and facing in its direction.

Preferably, the third disc element is provided along its outer edges with a further spacer element. Preferably, fixing means are provided between the further spacer and the outer edges of the third disk element. In a preferred embodiment, the further spacer element has a drying agent acting in the insulating glass volume. Preferably, the further spacer element is a so-called

Double spacer with both-side desiccant reservoir.

The further spacer preferably corresponds in its construction and its

Materials the spacer of the double glazing component, which is formed as a hollow base body, as described above. In contrast to the above

described spacer in the form of a hollow body is the other

Spacer Part of the closure component and not the double glass component. Embodiments relating to the construction and structure of the spacer of the double-glazing component are transferable to the further spacer of the closure component, and designs for the construction and structure of the further spacer of the closure component are transferable to the spacer of the double-glazing component because their structure and their structure can be identical.

The further spacer element preferably comprises at least one hollow basic body, which has a first disk contact leg and a second disk contact leg running parallel thereto, a first glazing inner leg, a second glazing inner leg and an outer leg. In the hollow

Basic body are a first hollow chamber and a second hollow chamber and a groove introduced. The first and second hollow chambers form the desiccant reservoirs. The groove extends parallel to the first disk contact leg and second

Disk contact legs. In the groove, the third disc element is arranged and fixed. The first hollow chamber adjoins the first glazing interior leg, while the second hollow chamber adjoins the second glazing interior leg, the glazing interior leg being above the hollow chambers, and the glazing interior leg

Outside leg is located below the hollow chambers. Above is in this

Connection as the insulating glass volume facing and below than the

Defined insulating glass volume away. Because the groove between the first

Glazing interior leg and second glazing interior leg runs, this limits laterally and separates the first hollow chamber and the second hollow chamber from each other. Groove side legs of the groove are thereby from the walls of the first

Hollow chamber or second hollow chamber formed. The groove forms a recess formed by the two groove side legs and a bottom surface of the groove, the bottom surface being formed by the outer leg.

The glazing interior legs are defined as the legs of the spacer in the form of a hollow base body or further spacer, which after the production of the double glazing component or the multiple insulating glazing in the direction of the

Show insulating glass volume. In the case of the multiple insulating glazing, the first glazing inner space limb lies between the first and the third glazing element, while the second glazing interior limb is arranged between the third and the second glazed element.

The outer leg of the spacer in the form of a hollow main body or further spacer is the side of the spacer or further spacer which lies opposite the glazing interior legs and points away from the insulating glass volume and possibly in the direction of an outer insulating film. The outer leg preferably extends perpendicular to the disc contact legs. However, the portions of the outer leg closest to the disc contact legs may alternatively be inclined in the direction of the disc contact leg at an angle of preferably 30 ° to 60 ° to the outer leg extending perpendicular to the disc contact legs. 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, which is optionally applied to the outer leg of the spacer. A planar outer leg, which in its entire course perpendicular to the disc contact legs, however, has the advantage that the sealing surface between spacers and

Slice contact legs is maximized and a simpler shaping

Facilitates production process. The spacer and / or the further spacer may include a plurality of grooves that can receive further disc elements. Alternatively, the disk elements may also be formed as a laminated glass pane.

The spacer in the form of a hollow basic body and / or the further spacer preferably has an overall width of 10 mm to 50 mm, particularly preferably of 20 mm to 36 mm, along the glazing interior leg. By choosing the width of the glazing interior leg, the distance between the first and third Disc element or determined between the third and second disc element. Preferably, the widths of the first glazing inner leg and the second

Glazing interior legs equal. Alternatively, asymmetric spacers are possible in which the two glazing interior legs have different widths. The exact dimension of the glazed interior leg depends on the

Dimensions of the modular system and the desired space between panes.

The spacer in the form of a hollow basic body and / or further spacers preferably has a height of 5 mm to 15 mm, particularly preferably of 5 mm to 10 mm, along the disc contact legs. The groove preferably has a depth of 1 mm to 15 mm, particularly preferably 2 mm to 4 mm.

The wall thickness of the spacer in the form of the hollow base body and / or further spacer is preferably 0.5 mm to 15.0 mm, more preferably 0.5 mm to 10.0 mm, particularly preferably 0.7 mm to 1, 0 mm.

The spacer and / or the further spacer preferably comprises one

Insulation film on the outer leg of the body, which is also referred to as outer insulation film, if it is a polymeric body. The insulating film comprises at least one polymeric layer as well as a metallic layer or a ceramic layer. The layer thickness of the polymeric layer is between 5 μm and 80 μm, while metallic thin layers and / or ceramic thin layers with thicknesses of 10 nm to 200 nm are used. Within the layer thicknesses mentioned a particularly good tightness of the insulating film is achieved.

Particularly preferably, the insulating film contains at least two metallic layers and / or ceramic layers, which are arranged alternately with at least one polymeric layer. In this case, the outer layers are preferably formed by the polymeric layer. The alternating layers of the insulation film can be applied to the

connected to various methods known in the art or

be applied to each other. Methods for the deposition of metallic or ceramic layers are well known to those skilled in the art. The use of an insulating film with alternating layer sequence is particularly advantageous in terms of the tightness of the system. An error in one of the layers does not lead to a loss of function of the insulation film. By comparison, even a small defect in a single layer can lead to complete failure. Furthermore, the application of several thin layers compared to a thick layer is advantageous because with increasing layer thickness the Danger of internal liability problems increases. Furthermore, thicker layers have a higher thermal conductivity, so that such a film is thermodynamically less suitable. The polymeric layer preferably comprises polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles,

Polyacrylates, polymethyl acrylates and / or copolymers or mixtures thereof. The metallic layer preferably contains iron, aluminum, silver, copper, gold, chromium and / or alloys or mixtures thereof. The ceramic layer preferably contains silicon oxides and / or silicon nitrides.

The outer insulation film preferably has a gas permeation of less than 0.001 g / (m ² h).

The composite of hollow base body and outer insulating film preferably has a PSI value of less than or equal to 0.05 W / mK, particularly preferably less than or equal to 0.035 W / mK. The insulating film can be applied to the hollow body, for example, glued.

The closure component preferably has a cover element which is formed with the closure sealant for gas-tight sealing of the insulating glass volume

co. The cover element is preferably selected from colored and uncolored glasses, colored and uncolored, rigid, clear plastics provided with a barrier to vapor diffusion. However, colored and uncolored glasses are preferably selected. Preferably, the colored and uncolored glass is selected from the group consisting of colored and undyed, unbiased,

semi-tempered and toughened float glass, cast glass, ceramic glass and glass. Float glass is particularly preferred. The cover element is preferably made of glass.

The closure sealant may e.g. As Butylband in a groove of the lid member and / or in a groove along the first and second sealing portion and the

Recording strut and / or spacer struts be inserted, such that the

Butyl tape acts against the glass of the first and the second disc element.

In a preferred embodiment, the cover element is dimensioned such that it can be sealingly fitted between the first disc element and the second disc element or that after insertion of the third disc element in the insulating glass volume on an outer edge of the first disc element and on a Outside edge of the second disc element comes to rest. After installation of the closure component in the double glass component, the cover element with the first

Disc element and the second disc element preferably flush. When the lid member is dimensioned to sealably fit between the first disc member and the second disc member, it is disposed between the first and second disc seal surfaces and is preferably two

Spacer struts and / or preferably on the receiving strut using the closure sealant on. When the lid member after insertion of the third disc member in the insulating glass volume on an outer edge of the first

Disc element and comes to rest on an outer edge of the second disc element, the closure sealant is preferably between the outer edges of the

Disc elements and the lid member arranged.

As already mentioned several times, the third disc element is preferably designed as an electrically controllable disc element and the cover element has from

Insulating glass volume to the outside leading electrical connections. That's it

Required that in the cover element outwardly guided electrical connections moisture-tight pass through the lid member. The production of such

moisture-proof passage, which throughout the life of the

Modular system may require special process steps. These are separately feasible on the third disc element and can then be tested for their quality, without even a structural combination with the

Double glazing component has taken place. Preferably, the cover element is non-destructively releasably fastened in its insulating glass volume sealing position. The third disc element can then be replaced or repaired from the finished manufactured multiple insulating glazing if necessary. Advantageously, the modular system by mechanically acting clamping means

characterized in that the cover element is non-destructively releasably pressed with a holding force gas-tight in the double-glazed component in the arrangement of the closure member to the double glazing component.

The invention further relates to a Mehrfachisolierverglasung, comprising the

Modular system, wherein the closure member is arranged on the receiving opening such that the third disc element in the insulating glass volume of

Double glazing component is introduced and the closure sealant between the Closing member and the double glazing component is arranged circumferentially around the receiving opening, so that it closes the insulating glass volume gas-tight.

Furthermore, the invention relates to a method for producing the Mehrfachisolierverglasung, comprising the steps

- providing the modular system,

Inserting the third disc element into the insulating glass volume of the

Double glazing component and arranging the closure member and the closure sealant at the receiving opening, such that the closure member with the VerschlüssDichtmittel closes the insulating glass volume gas-tight.

Modular system for multiple insulation glazing. The modular system shown here has two components, namely a double glazing component 1 and a closure component 2 with closure sealing means, not shown, which are used to produce a

Dreiisolierverglasung in the double glazing component 1 as indicated by the arrow can be arranged by inserting. The double glazing component 1 has a first pane element 1.1 with a first pane sealing surface, a second pane element 1.1

Disc member 1.2 having a second disc sealing surface, and a spacer disposed between the first disc sealing surface and the second disc sealing surface. The spacer is constructed from a plurality of spacer struts 1.3, which encompass an insulating glass volume between the first disk element 1.1 and the second disk element 1 .2 and gas-tight by means of fixing means 1 .4 at the first

Disc sealing surface and are fixed to the second disc sealing surface. The plurality of spacer struts 1.3 are formed as a sectionally open frame and arranged so that between two spacer struts 1.3 a receiving opening 1 .5 is formed, which is dimensioned such that through this a fastened to the closure member 2 third disc element 2.1 in the insulating glass volume 3 of

Double glazing component 2 can be introduced.

One of the spacer struts 1 .3 is formed as a receiving strut 1.31 and has a receiving opening 1.5, which is dimensioned so that through them the third

Disc element 2.1 can be introduced into the insulating glass volume. The

Recording strut 1 .31 surrounds the receiving opening 1.5 on all sides. Adjacent

Following on the receiving strut 1 .31 is located on the first disc element 1 .1 a first sealing portion 1.6 and on the second disc element 1 .2 a second

Sealing section 1 .7 free.

The third disc element 2.1 is part of the closure component 2, which in addition to the insertable into the double glazing component 1 third disc element 2.1 continues a

Closure sealing means (not shown) for gas-tight sealing of the insulating glass volume by the closure member 2 after arranging the closure member 2 at the

Receiving opening 1.5 is provided. The closure member 2 further includes

Cover element 2.2, which cooperates with the closure sealant for gas-tight sealing of the insulating glass volume 3. The cover element 2.2 is dimensioned such that it can be fitted sealingly between the first disk element 1.1 and the second disk element 1 .2. The third disk element 2.1 is electrically controllable Disc element formed. The cover element 2.2 has, purely by way of example, two electrical connections 2.7 leading from the insulating glass volume to the outside.

The spacer struts 1 .3 are formed as hollow body. The hollow

The base body has two parallel disc contact legs (not shown), an outer leg 1 .32 and two glazing inner legs 1 .33, one of which can be seen. In the hollow body at least partially a desiccant is arranged (not shown). The hollow base body extends between the first disk element 1 .1 and the second disk element 1.2. While the first disk contact leg (not shown) is fixed to the first disk sealing surface of the first disk element 1 .1, the second disk contact leg (not shown) is fixed to the second disk sealing surface of the second disk element 1 .2.

Fig. 2 shows a possible further embodiment of the invention

Modular system. The modular system shown in Fig. 2 corresponds to the modular system shown in Fig. 1 with the differences that the spacer no

Recording strut has 1.31. The spacer struts 1 .3 are along the

Disk edges of the outer disks 1 .1, 1.2 arranged in a U shape. At the top, the spacer strut is completely missing, so that the receiving opening 1 .5 forms between the two vertically extending spacer struts 1.3. Furthermore, the third disc element 2.1 of the closure component 2 is surrounded along its outer edges with a further spacer element 2.4. This further spacer element 2.4 is designed as a so-called double spacer. This has two mutually parallel hollow chambers for receiving desiccant, which are separated by a groove. With this groove, the further spacer element can be placed on the outer edges of the third disc element 2.1. The outer edges of the third disc element 2.1 are thereby protected when the cover element 2.2 is joined to the double glazing component 1. FIG. 3 shows a cross section of the second embodiment of the invention shown in FIG

Modular system in the assembled state, i. the closure member 2 has been inserted in the double glazing member 1 in the arrow direction and disposed therein, so that a Mehrfachisolierverglasung is formed. The cross-sectional plane is illustrated in Figure 2 with III. Fig. 3 therefore shows a triple insulating glazing after completion. Between the first disc element 1 .1 and the second disc element 1.2 is the

Spacer strut arranged 1.3 and by means of fixing 1.4 at the first

Disc sealing surface and gas-tight fixed to the second disc sealing surface. The Closure member 2 is inserted into the double glazing component 1 such that an insulating glass volume 3.1 between the first disc element 1 .1 and the third

Disc element 2.1 and a further insulating glass volume 3.2 between the second disc element 1 .2 and the third disc element 2.1 are formed, the

separated from each other by the third disc element 2.1 together with further spacers 2.4, which is arranged along the outer edges 2.3 of the third disc element 2.1.

The further spacer 2.4 is formed as a hollow and preferably polymeric body in the form of a so-called Doppelspacers, which may be glass fiber reinforced. The further spacer 2.4 comprises a first disk contact leg 2.41, a second disk contact leg 2.42 running parallel thereto, a first disk contact leg 2.41

Glazing interior legs 2.43, a second glazing interior leg 2.44 and an outer leg 2.45. Between the outer leg 2.45 and the first glazing inner leg 2.43 there is a first hollow chamber 2.46, while a second hollow chamber 2.47 between the outer leg 2.45 and the second

Glazing interior leg 2.44 is arranged. Between the two hollow chambers 2.46, 2.47 there is a groove 2.48, which runs parallel to the disc contact legs 2.41, 2.42. Two groove side legs (not shown) of the groove 2.48 are thereby formed by the walls of the two hollow chambers 2.46, 2.47, while a bottom surface (not shown) of the groove 2.48 is directly adjacent to the outer leg 2.45. The outer leg 2.45 runs mostly perpendicular to the disc contact legs 2.41, 2.42 and parallel to the glazing interior legs 2.43, 2.44. The glazing interior legs 2.43, 2.44 have openings (not shown) at regular intervals, each of which connects one of the hollow chambers 2.46, 2.47 with the respective insulating glass volume 3.1, 3.2. The first cavity 2.46 and the second cavity 2.47 are at least partially filled with a desiccant 2.5, which can absorb humidity from the insulating glass volume 3.1, 3.2. The first disc contact leg 2.41 is fixed to the first disc element 1 .1, and the second disc contact leg 1.2 is fixed to the second disc element 1.2. The glazing interior legs 2.43 and 2.44 adjoin the insulating glass volume 3.1 and 3.2, respectively. The first glazing interior leg 2.43 lies between the first disk element 1.1 and the third disk element 2.1, while the second

Glazing interior leg 2.44 between the third disc element 2.1 and the second disc element 1 .2 is arranged. The outer leg 2.45 represents the the

Glazing interior legs 2,43, 2.44 opposite side of the other Spacer 2.4, which point away from the insulating glass volume 3.1, 3.2. The outer leg 2.45 is arranged either adjacent to the spacer struts 1.3 or the cover part 2.2. The groove 2.48 surrounds the outer edges 2.3 of the third

Disc element 2.1.

The closure component 2 has the electrical connection 2.7, which is arranged in a gas-tight manner through the cover part 2.2 such that the electrical connection 2.7 electrically contacts the third pane element 2.1 designed as a functional glass pane. FIG. 4 a shows a further cross section of the invention shown in FIG. 2

Modular system in the assembled state, i. the closure member 2 is inserted in the double glazing member 1 in the arrow direction and disposed therein, so that a Mehrfachisolierverglasung is formed. The section plane is illustrated by the designations IVa. Fig. 4a therefore shows a triple insulating glazing after completion. Between the first disc element 1 .1 and the second disc element 1.2 are two

Spacer struts 1 .3 arranged and by means of fixing 1 .4 at the first

Disc sealing surface and gas-tight fixed to the second disc sealing surface. The two spacer struts 1 .3 are between opposite edges of the two

Disc elements 1.1, 1.2 arranged. The insulating glass volume 3.1 is between the first disk element 1 .1 and the third disk element 2.1, and the other

Insulating glass volume 3.2 is formed between the second disk element 1.2 and the third disk element 2.1, so that they are separated from each other by the third

Disc element 2.1 together with further spacers 2.4 are separated, which is arranged along the outer edges 2.3 of the third disc element 2.1.

4b shows a cross section of a modular system according to the invention in another possible embodiment. The modular system is to one

Multiple insulating glazing joined together. FIG. 4b shows a cross-sectional view of a variant of the modular system shown in FIG. 4a. The shown in Fig. 4b

Embodiment corresponds to the embodiment shown in Fig. 4a with the difference that the third disc element has at least two sub-disc elements 2.1 1, 2.12, which are interconnected and fixed by at least one holder 4. The holder 4 is designed such that it surrounds the first sub-disc element 2.1 1 at its inner edge 2.13 and the second sub-disc element 2.12 at its inner edge 2.14, while the outer edges 2.3 of the sub-disc elements 2.1 1, 2.12 in the groove 2.48 of Spacer 2.4 are arranged. 5 shows an enlarged partial view of the modular system shown in FIG. 3 in the region of the closure component 2. The modular system is associated with FIG

Multiple insulating glazing joined together. The first disk contact leg 2.41 is arranged on the first disk element 1 .1, and the second disk contact leg 2.42 is arranged on the second disk element 1.2. The first

Glazing interior leg 2.43 is adjacent to the first insulating glass volume 3.1, and the second glazing interior leg 2.44 is adjacent to the second insulating glass volume 3.2. The outer leg 2.45 is arranged adjacent to the cover part 2.2. The third disc element 2.1 is arranged in the groove 2.48. The cover element 2.2 lies on an outer edge 1 .8 of the first disc element 1.1 and on an outer edge 1 .8 of the second disc element 1 .2.

FIG. 6 a shows a further enlarged partial view of the modular system shown in FIG. 5 in one possible embodiment. Between the second disc element 1 .2 and the second disc contact leg 2.42 a closure sealant 2.6 is arranged in the form of a butyl rubber layer. Before merging

Double glazing component 1 and closure component 2, the closure sealant 2.6 can be fixed either on the double glazing component 1 or on the closure component 2. It is also conceivable that it is arranged in sections on the double-glazed component 1 and in sections on the closure component 2, provided that the required gas-tightness is ensured in the mounted state.

Fig. 6b shows an enlarged partial view of the modular system shown in Fig. 5 in a further possible embodiment. As an alternative or in addition to the embodiment shown in FIG. 6a, the modular system between the outer edge 1.8 of the second disc element 1 .2 and the cover part 2.2 can have a sealing closure sealant 2.6 arranged in a groove, for example in the form of a butyl rubber cord. With regard to the structural arrangement of the closure sealant 2.6 prior to assembly, the statements made for Figure 6a apply accordingly. LIST OF REFERENCE NUMBERS
