Description

description

Technical Field The present invention relates to glazing. The invention further relates to methods for producing a glazing and to the use of the glazing.

BACKGROUND AND PRIOR ART [0002] Glazings are used in large numbers both for exterior facades of buildings and in the interior of buildings. In the interior, glazings are used, for example, to separate different areas, for example publicly accessible and non-public areas in buildings of companies, authorities, public institutions, etc. In addition to aesthetic and decorative requirements, a number of functional requirements are typically to be fulfilled, in particular climatic decoupling. acoustic decoupling (noise protection) and fire protection. The weighting of the individual requirements may vary depending on the specific application. The required glass surfaces - for example in the prestigious entrance area of a company - can be very large and heavy and have an area of several square meters.

EP 1 194 673 B1 discloses a glazing in which at least two fire protection glass plates are arranged at a distance from one another and a sealing arrangement is arranged between the fire protection glass plates. Each of the fire protection glass plates consists of at least two parallel glass plates, between which a fire protection layer is located. In the area of the connection of the two fire protection glass plates, the fire protection layer does not extend to the edge of the glass plates, but stands behind them. The resulting grooves between the glass plates are filled with a barrier material, which protects the fire protection layer from atmospheric contact.

It is a general object of the present invention to provide improved glazing. The glazing provided should be easy to handle for assembly and, if necessary, non-destructive dismountable.

The object is achieved in a general form by the subject matter of the independent claims. Particularly advantageous and further exemplary embodiments are defined by the subject matter of the dependent claims as well as the entire disclosure of the present document.

According to one aspect, the object is achieved by providing a glazing. A glazing according to the invention comprises a first and a second glazing module. The first and second glazing modules each comprise an outer glass element and an inner glass element spaced and preferably parallel to the outer glass element.

The first and the second glazing module further each comprise a connecting device arranged along an end face of the glazing module between its outer glass element and its inner glass element, wherein the connecting device comprises at least one plug element running along the end face.

The first and the second glazing module are detachably plug-connected by means of the at least one plug-in element of the first glazing module and the at least one plug-in element of the second glazing module, preferably flush-connected.

In addition to the first and second glazing module further glazing modules may be present, which are connected to each other and to the first and / or second glazing module in the same manner as the first and second glazing module according to the following illustration.

The terms "inside" and "outside" in this document generally refer to the space areas on both sides of a surface element, in particular a glazing module, a glass plate, etc. They do not imply special application and / or installation position of the elements concerned.

The front and rear glass element of each glazing module may in principle be curved or bent, but in typical embodiments has the shape of a flat plate with parallel outer surfaces. Likewise, each of the glazing modules is typically a planar sheet. The first and second glazing modules may be arranged at an angle to each other. Typically, however, the front and rear outer surfaces are each in a plane, so that the glazing is also a total of a planar surface element. The first and second glazing module can be aligned in particular to shock, wherein between the end faces of the glass elements of the first and second glazing module in each case a distance, typically in the millimeter range, may exist.

A direction between "inside" and "outside", i. E. a direction across a surface element, e.g. a glass element, hereinafter also referred to as «transverse direction». A direction along or tangential to a surface element is called "longitudinal direction".

The connecting device and in particular the at least one plug-in element of the connecting device advantageously extends over the entire longitudinal extent of the respective end faces of the first and second glazing module. In this document, a "face" is described as a side transversely (typically perpendicular) to the areal major extent of a surface element. The connecting device can also serve as a spacer between the outer and inner glass element of the glazing modules. In embodiments with an additional fire-resistant glass element, as shown in more detail below, the connecting device can serve as a spacer between the outer and inner glass element and the fire-resistant glass element.

The plug-in elements of the two glazing modules are designed for producing a positive connection. The plug connection makes it possible to provide a large glazing in the form of easily manageable glazing modules of limited size and to connect or assemble them on site. Since the connector is detachable, the glazing can be disassembled or dismantled into the glazing modules if necessary.

In one embodiment, the at least one plug-in element of the first and second glazing module in each case comprises a groove extending along an end face of the first glazing module or of the second glazing module. An intermediate element engages in the assembled state in the groove of the first and second glazing module.

In such an embodiment, the connection of the glazing modules via a tongue-and-groove connection is made, wherein the first and second glazing module each comprises a groove and the intermediate element is the spring. Typically, the grooves and the spring extend at least substantially over the entire edge length of the end face. The connecting device of the first and second glazing module may comprise, for example, a respective U-profile element extending along the end face and open towards the end face, wherein the interior of the U-profile represents the groove. Since intermediate element may be a rod-shaped square element with a rectangular cross-section.

The U-profile elements and the intermediate element are made of a particular material from the point of view of mechanical stability and possibly the thermal requirements in case of fire selected material, typically made of metal. In particular, they can be made of steel.

For a pure positive connection, the intermediate element can engage in the grooves of the connecting devices of both glazing modules with relatively little friction and thus be released from both grooves again. Alternatively, the intermediate element may be firmly inserted into the groove of one of the two connection devices, e.g. be pressed in, glued or pinned.

In a further embodiment, the connecting device of one of the glazing modules knows a spring as an integral part and the connecting device of the other glazing module has a corresponding groove. In a further variant, the connecting devices of both glazing modules have alternating tongue and groove sections over the length of the front side.

The connecting means, for example the U-profile elements, are preferably with the front and / or rear glass element by a suitable, preferably heat-resistant and for (smoke) gas largely impermeable adhesive, e.g. a polisulfide-based adhesive, e.g. Kömmerling type GD 115, glued. The adhesive may e.g. be applied by screen printing in an edge region of the outer and / or inner glass element.

In one embodiment, at least the outer glass element or the inner glass element of the first and the second glazing module are each a single-pane safety glass. In a further embodiment, both the outer and the inner glass element are each a single-pane safety glass. The typical thickness of the tempered safety glass or tempered safety glass is in a range of e.g. 4 mm to 10 mm, for example 6 mm.

In one embodiment, the first glazing module and the second glazing module each comprise a fire protection glass element. The fire protection glass element is in each case spaced between the outer glass element and the inner glass element of the first or second glazing module and preferably arranged in parallel. The distance between each of the outer or inner glass element and the fire protection glass element is in a typical range of e.g. 10 mm to 20 mm, for example 15 mm.

In a typical embodiment with fire-resistant glass element, both the outer and inner glass element and the fire-resistant glass element are flat plate-shaped or disc-shaped surface elements. The fire-resistant glass element is used in a basically known manner, especially the thermal decoupling of the separated by the glazing areas in case of fire.

In one embodiment, the fire protection glass element comprises a sandwich structure with at least two glass plates and a fire protection layer arranged between the glass plates. In some cases, to achieve the required fire protection effect, a multilayer sandwich structure with e.g. three glass plates and two fire protection layers required. The thickness or thickness of the individual glass plates and fire protection layers can be the same or different and is typically in the range of a few millimeters. By way of example, the glass plates and fire protection layers may each have a thickness of 5 mm, such as Nano Pyro, Saint Gobain or Promat.

In one embodiment, the at least two glass plates and the fire protection layer on one end face of the fire protection glass element are flush with each other. In such an embodiment, in contrast to, for example, the disclosure of EP 1 194 673 B1, between the individual glass plates in the end face no grooves, but the front surface is at least substantially planar. The end face of the fire-resistant glass element is typically parallel to the end faces of the inner and outer glass element and may, as aligned further below, also be aligned therewith. In typical embodiments, the fire protection layer and the glass plates are flush at all end faces along the circumference of the fire protection glass element and the glass plates are congruent in their surface.

In one embodiment, in each case one end face of the outer glass element, the inner glass element are arranged in alignment with each other in the first and second glazing module. Preferably, an end face of the fire protection glass element is then arranged in alignment with the end faces of the outer and inner glass elements or set back from them.

In one embodiment, the connecting device of the first and second glazing module respectively comprises an outer plug element connected to the outer glass element and an inner plug element connected to the inner glass element. The outer plug-in element and the inner plug-in element are preferably spaced apart from one another. In an embodiment with additional fire-resistant glass element, as described above, the fire-resistant glass element between the outer and inner plug element can be arranged and connected to these materially bonded, in particular glued, for example with a polysulfide-based adhesive, as mentioned above. The outer or inner plug element can also serve as a spacer between the outer or inner glass element on the one hand and the fire protection glass element on the other. The outer and inner male members may be structurally separate, e.g. in the form of separate U-profile rails, or may be integrally formed, e.g. in the form of a common rail.

In the mounted state of the glazing in each case the two outer and the two inner plug-in elements of both glazing modules are plugged together.

In one embodiment, in a connecting region between the first and second glazing module in the longitudinal direction in each case a gap between the outer and inner glass element at least partially filled with a fibrous insulating material, in particular mineral wool.

In one embodiment with a distance or gap between the respective outer and the respective inner glass elements of the glazing modules, the insulating material can be arranged in particular in this gap and fill it completely or partially. The insulating material may also overlap longitudinally with the inner and outer glass elements of the glazing modules.

In an embodiment with outer and inner plug-in elements, as previously shown, insulating material can be arranged in particular in the transverse direction in a region between the outer and inner plug-in elements.

In one embodiment, each between the outer glass element and the inner glass element of the first and second glazing module existing cavity is sealed, in particular sealed gas-tight. For sealing, sealing elements are preferably provided, which are e.g. can be incorporated or recessed in the connecting device and / or can be provided as separate sealing elements. A seal is preferably provided at least in each case at the front sides of the first and second glazing module connected via the connecting devices. Preferably, however, the first and second glazing modules are sealed at all faces of their circumference.

According to a further aspect, the object is achieved by providing a method for producing a glazing. The method preferably comprises the following steps: a) providing a first and a second glazing module. The first and second glazing modules each comprise an outer glass element and an inner glass element which is at a distance from the outer glass element and is preferably parallel. The first and second glazing modules further each comprise a connecting device arranged along an end face of the glazing module between its outer glass element and its inner glass element, wherein the connecting device comprises at least one plug element running along the end face; b) releasable plug-in connection, preferably flush-mounted plug-in, of the first and second glazing module by means of the at least one plug-in element of the first glazing module and the at least one plug-in element of the second glazing module.

The first and second glazing modules may in particular be glazing modules according to any embodiment of a glazing module according to the disclosure.

According to a further aspect, the object is achieved by using a glazing of an inventive glazing for fire protection.

In the figures, typically only one is provided with reference numerals for multiple features. Furthermore, in several figures in the same or analogous manner existing features are not provided in each of the figures with reference numerals.

EXEMPLARY EMBODIMENTS [0037] Reference will first be made below to FIG. 1 shows an exemplary glazing 1 or a section of such a glazing with a first glazing module 10a and a second glazing module 10b in cross section of a plan view.

Each of the two glazing modules 10a, 10b comprises an outer glass element 100a and an inner glass element 100b, which for example have an identical structure. "Inside" and "outside" are interchangeable.

Each of the glazing modules 10a, 10b further comprises a multilayer fire-resistant glass element 103, which is arranged in each case in the interior of the glazing modules 10a, 10b between the outer glass element 100a and the inner glass element 100b parallel and spaced therefrom. The inner space between the outer glass member 100a and the inner glass member 100b is divided into an outer space between the outer glass member 100a and the fire glass member 103 and an inner space between the fire glass member 103 and the inner glass member 100b. The arrangement of Fig. 1 is exemplary symmetrical, i. The distance between the outer glass element 100a and the fire protection glass element 103 measured perpendicular to the surfaces of the glass elements or the fire protection glass element corresponds to the distance between the fire protection glass element 103 and the inner glass element 100b. The fire protection glass element 103 is constructed in a basically known manner as a sandwich of a plurality of layers of glass plates 103a and intermediate fire protection layers 103b. The edges of the fire protection glass element 103 are in each case in a basically known manner by a film (not referenced) edged and protected.

The glazing modules 10a, 10b also each comprise a connecting element. By way of example, the connecting element in each case comprises an outer and inner plug-in element 101 disposed in the interior of the glazing element 10a, 10b, wherein the outer plug-in element 101 is connected to the outer glass element 100a and the inner plug-in element 101 is connected to the inner glass element 100b. Each of the plug-in elements 101 is connected to the associated glass element 100a or 100b by means of a heat-resistant adhesive element 105, the adhesive element 105 being e.g. a generally known polisulfide-based adhesive, e.g. Kömmerling type GD 115, is. The adhesive member 105 is defined by a sealing member 102, e.g. Thiokol, for example Kömmerling type GD 823, supplemented, e.g. is applied in the screen printing process in an edge region on the inside of the glass elements 100a, 100b. The sealing element 102 serves the smoke gas-tight seal. The plug-in elements 101 are made of a heat-resistant material to the required extent, e.g. from steel.

The plug-in elements 101 are rod-shaped or rod-shaped and extend perpendicular or transversely perpendicular to the sectional plane of Fig. 1 along the edge of the glass elements 100a, 100b, at least substantially over its entire length. The plug-in elements 101 have a basically U-shaped cross-section, with the open sides of the respective outer and inner plug-in elements 101 of the first and second glazing module 10a, 10b facing each other. The base of the U-profile is formed by a hollow portion 101 a with a hollow, rectangular cross-section, wherein the legs of the U-profile relative to the portion 101 are set back with a rectangular cross-section, so that in each case a step is formed, which by the adhesive member 105 and the additional sealing element 102 is completed. The interior of section 101a is preferably filled with a hygroscopic desiccant 101b, typically in granular or granular form, which absorbs moisture residues. The contact with the external and internal internal spaces is through openings, e.g. in the form of a perforation in the walls of section 101a.

Furthermore, the glazing 1 according to Fig. 1 comprises an outer and an inner intermediate element 11. The intermediate elements 11 are, like the plug-in elements 101, bar or rod-shaped and also made of a sufficiently heat-resistant material, e.g. Steel, made. In the exemplary embodiment shown, the intermediate elements 101 have a solid rectangular cross-section.

The outer and inner plug-in elements 101 each form together with the outer or inner intermediate element a positive tongue-and-groove connection, wherein the interiors of the U-profiles, as shown above, in each case a groove and the intermediate element 11 forms a spring , In the embodiment shown, the intermediate element 11 is in each case non-destructively releasably inserted with slight play or possibly small excess in the U-profiles. In alternative

According to embodiments, the intermediate element 11 is non-destructively non-destructively connected to one of the plug-in elements 101, and is e.g. pressed in, glued in, pinned, or similar In a further embodiment variant, the intermediate element 11 is integrally formed in each case with one of the plug-in elements 101. This plug-in element then has no U-shaped groove, but a spring projecting beyond the other end face of the glazing module.

Through the connection of the glazing modules 10a, 10b by tongue and groove connection they can be mounted in a simple manner on site by plugging together and also as needed also non-destructively detached from each other.

The fire-resistant glass element 103 of the first and second glazing module 10a, 10b is respectively disposed between the outer and inner glass element 100a, 100b and also connected thereto via an adhesive member 102 as shown above. The plug-in elements 101 serve at the same time as spacers between the glass elements 100a, 100b on the one hand and the fire protection glass element 103 on the other.

At its base, the plug-in elements 101 and their hollow portion 101a, as shown above, each sealed with a gas-tight, in particular for flue gas, impermeable sealing element 105. The sealing element may e.g. each consist of butyl rubber. In order to receive the sealing element 105, chamfers extending over the length of the plug-in elements 101 are provided at the base of the plug-in elements 101 or their section 105. As can be seen from FIG. 1, the respectively opposite outer or inner glass elements 100a, 100b do not abut each other directly with their end faces, but instead have a gap between them. There is also a gap between the fire protection glass elements 103 of the first and second glazing module 10a, 10b. The gap between the two fire protection glass elements is filled with an insulating material 12, for example, mineral wool. Alternatively or in addition to mineral wool, the insulating material 12 may include other materials, e.g. Wood and / or putty material.

While Fig. 1 illustrates the interaction of two glazing modules 10a, 10b, the glazing 1 may also consist of a larger number of glazing modules, which are each connected in pairs in the manner shown in Fig. 1.

2, which represents a further exemplary embodiment of a glazing 1 in a Fig. 1 corresponding sectional view with exemplary dimensions.

The glazing according to FIG. 2 differs from the glazing according to FIG. 1 in that the glazing modules 10a, 10b according to FIG. 2 have no fire protection glass element 103, but only one outer glass element 100a and one inner glass element 100b. Accordingly, the internal space between the outer glass member 100a and the inner glass member 100b is continuous and continuous, respectively.

Further, in this embodiment, the connecting device of each of the glazing modules 10a, 10b has a double male member 101 ', each having two U-shaped grooves. The double plug-in element 101 'replaces the respective two plug-in elements 101 of the embodiment shown in FIG. 1 and also serves as a spacer between the respective outer glass element 100a and the inner glass element 100b.

In the following, reference is additionally made to FIG. 3. FIG. 3 shows a further embodiment of the glazing 1, which basically has a similar structure to the embodiment according to FIG. 1 in a view corresponding to FIG. 1.

In contrast to the embodiment according to FIG. 1, the fire protection layers 103b of the fire protection glass elements 103 at the mutually facing or opposite end faces of the glazing modules 10a, 10b respectively behind the glass plates 103a back, so that between the glass plates slots or grooves arise. These slots or grooves are each formed by an arrangement of an adhesive element 102 'adjacent to the fire protection layer 103b, e.g. from Thiokol and a spacer 104 adjacent to the insulating element 12, so that the individual layers of the fire-resistant glass element are flush with one another and form a common planar end face. The edging of the edge represented by a foil in FIG. 1 can be dispensed with in this embodiment. The spacer 104 consists of a rod-shaped or rod-shaped hollow profile of square cross-section, which, like the hollow portion 101a of FIG. 1, is filled with desiccant and also has perforated conversions. Furthermore, gas-tight, in particular smoke gas-tight, seals of the spacers 104 are provided with cord-like sealing elements made of butyl rubber (not referenced).

The adhesive elements 102 'may be e.g. made of the same material as the adhesive elements 102. Spacers 104 may be e.g. consist of the same material as the plug-in elements 101. They are exemplary designed as a rod-shaped hollow profiles with a square cross-section.

In the following, reference is additionally made to FIG. 4. 4 shows, by way of example, a possibility for the connection of a glazing module 10a to a building wall 2. Instead of a wall 2, the connection can take place analogously with a further building element, for example a floor or a ceiling.

The building wall 2 comprises a wall element 20 which is e.g. bricked or made of concrete or is formed by a prefabricated element basically known type. On its side facing the glazing module 10a, a rod-shaped or rod-shaped profile element 21 is mounted or integrated on the wall element, wherein the profile element 21 is formed by a U-profile open towards the glazing module 10a and e.g. made of steel. The profile element 21 is dimensioned so that the two legs of the U-profile engage in the grooves of the plug-in elements 101 of the glazing module 10a and hold it with respect to the wall element 20 and thus serves as a spring element. In this way, the glazing module 110a is releasably and reconnectably connected to the wall element 20. The structure of the connecting device of the glazing module 10a is preferably identical to a connecting device for connection to other glass elements, as described above.

Correspondingly, glazing modules may e.g. be provided on opposite ends in each case with an identical connection device and thus allow both a connection with other glazing modules as well as with other building elements.

In the example shown in FIG. 4, the leg length of the U-profile 21 is further dimensioned by way of example such that a gap remains between the glazing module 10a and the wall element 20.

The connection of the building wall 2 or another building element and a glazing module can also be done in other ways. Thus, in particular instead of the profile element 21, two plug-in elements 101 each having a groove or a combined plug-in element 101 'according to FIG. 2 can be provided and the connection can take place via separate springs in the form of intermediate elements 11.

In the following, reference is additionally made to FIG. 5. Fig. 5 shows by way of example a further glazing with a plurality of glazing modules 10, which e.g. the glazing modules 10a, 10b according to one of FIGS. 1 to 3 correspond, as well as door elements. 3
