    Description Field of the Invention The invention relates, in a first aspect, to a fire-resistant glazing for a building opening, which fire-resistant glazing is profiled within the glass surface and has at least one glass door and at least one glass fixed element for attachment in the building opening the door is struck. In a further aspect, the invention relates to the attachment of a lock and / or fittings on a fire-resistant glazing. The two aspects can each be provided separately or in combination.
    BACKGROUND [0002] EP 2 581 515 A1 discloses a profile-less fire-resistant glazing of the type mentioned. This fire-resistant glazing has at least two existing fire panels and juxtaposed glass surfaces. The one glass surface has a swivel or swing door, which is held profile-free directly on the other glass surface, which forms the lateral fixed element to the door. This fire-resistant glazing completely dispenses with profiles made of wood or metal in the glass surface, which is why such fire-resistant glazing is referred to as "profileless". The absence of profiles in the glass surface results in a high light transmission and results in a visually light-looking design. This is advantageous if, as a replacement for an existing, fire protection technology insufficient but architecturally inconspicuous designed glazing with door a current fire safety standards appropriate glazing should be provided. In such fire-resistant glazings fire protection panels are used in practice, which have two by means of a so-called edge joint parallel spaced refractory glass sheets which are interconnected by the edge bond, which takes over the attachment function for attaching the two glass panes together. The enclosed space between the refractory glass panes is filled with a fire protection gel.
    DESCRIPTION OF THE INVENTION [0003] The invention is based on the object of providing an improved profile-free fire-resistant glazing.
    This is achieved in the fire-resistant glazing of the type mentioned by the characterizing features of claim 1.
    With the inventive solution a significantly improved transparency of the fire-resistant glazing is achieved by the solution is not only profillos, but due to the special structure of the door and the fixed element is also randverbundlos. This both for the glass of the door and for the glass of at least one solid element. This results in the optical equality to a non-fire protection, conventional Gla-door completion. This is particularly important in the field of use in listed buildings, if a non-fire-retardant glass door is to be replaced by a fire-resistant glass door. Even with architecturally demanding new build solutions, there are maximum transparent solutions with both profile-free and edge-bonded glass door connections.
    In a preferred embodiment of the fire-resistant glazing, this includes the lateral fixed element with the inventive structure, on which the door is posted and at least one second fixed element with the inventive structure, which is arranged above the door. In a further embodiment, fixed elements with the structure according to the invention are present on both sides of the door, and at least one further fixed element with the construction according to the invention is arranged above the door. When the term door is used in the context of the invention, this includes both doors with a door leaf and doors with more than one door leaf.
    The invention is further based on the object to enable improved attachment of a lock or fittings in a fire-resistant glazing. This may be a conventional fire-resistant glazing, but preferably the fire-resistant glazing according to the present invention.
    This object is achieved by a fire-resistant glazing with a lock and / or with fittings according to claim 4 or claim 5.
    The attachment of a lock or a fitting in the fire-resistant glazing according to the invention provides a simple attachment and a good fire protection effect. It is particularly preferred for the previously described fire-resistant glazing, but can also be used in conventional fire-resistant glazing. The annular plastic parts, in particular synthetic resin and in particular epoxy resin parts prevent excessive stress on the glass and can be equipped particularly well fire-resistant.
    Preferably, the fitting receptacle is in each case fastened in a recess in the door or in the solid element by means of an adhesive bond and between the material of the adhesive bond and the fitting receptacle an intumescent fire protection seal is arranged, which results in a particularly simple and fireproof attachment. In particular, the adhesive bond is formed by a silicone adhesive.
    BRIEF DESCRIPTION OF THE DRAWINGS Further embodiments, advantages and applications of the invention will become apparent from the dependent claims and from the following description with reference to the figures. Showing:
    Figure 1 is a plan view of an example of a fire-resistant glazing with a door in a building opening.

    Way (s) for carrying out the invention Fig. 1 shows a profileless fire-resistant glazing 1, which is arranged in a building opening. The building opening is defined by the surrounding building parts 2, which are formed of a building material other than glass, for example concrete or bricks, and which are only indicated in the figure. The exemplary fire-resistant glazing comprises a first solid element 3 made of glass and a second solid element 5 made of glass. Above the door 4, a further fixed element 7 is arranged. In its simplest embodiment, such a fire-resistant glazing has only the fixed element 3 (or the fixed element 5) and the door 4 hinged thereto, which has the same height as the fixed element, so that the fixed element 7 is not present above the door. The door is fixed to the fixed element in a generally known manner with fittings 9 pivotally. On the opposite side of the door, a fitting in the form of a lock 6 is provided with the door handle 8, which is also basically known. A preferred embodiment of the attachment of the fittings or the lock on the glass surfaces is explained in a second aspect of the invention below.
    First, the inventive structure of the door and the at least one fixed element will be explained. 2 shows a horizontal section along the section line A-A of FIG. 1 and thus shows a horizontal section through part of the door 4 and through part of the fixed element 3.
    The door 4 has in its interior a multi-layer, clear transparent fire protection glass 10. In this, a plurality of glass layers 15 are present and fire protection layers 16 are provided between the glass layers. All glass layers of the fire protection glass 10 are preferably float glass panes of the same thickness, wherein in the figure this thickness is given as an example with 3 mm. In the spaces between two such glass layers, the transparent fire protection layers are embedded, which foam in the event of fire and form an opaque heat shield. Such layers are also referred to as reactive fire protection layers or thermal transformation layers. The fire protection layers are indicated in the figure, for example, with the thickness of 1 mm. Such fire protection glasses 10 are known. A corresponding commercially available fire-resistant glass is known from the manufacturer Schott AG, Germany, under the name PYRANOVA®.
    According to the invention, a single-pane safety glass 11 and 12 is provided on both sides of the fire protection glass 10, which is laminated directly to the respective outer float glass of the fire protection glass 10. The thickness of the two single-pane safety glasses is given in the figure as an example with 8 mm each. The laminating film is designated 11 'and 12' and is given as an example with the thickness of 1.5 mm. The lamination of glass panes is basically known to the person skilled in the art. When laminating glass, at least two sheets of glass are bonded together by means of an adhesive layer in the form of a laminating film. The adhesive layer is usually polyvinyl butyral films or ethylene-vinyl acetate copolymer films, with the aid of which laminated glass can be produced. A tempered safety glass (ESG) is known to consist of a single, specially heat treated disc and must be cut before its heat treatment, since subsequent processing is possible only to a very limited extent. Due to the heat treatment, the ESG washers 11 and 12 have increased impact and impact resistance and are insensitive to large temperature differences.
    According to the invention, the toughened glass panes 11 and 12 are dimensioned and laminated onto the fire protection glass 10 that protrude at least one end face, but in particular on all end faces of the door 4, these panes ESG over the fire protection glass and thus a side of form the ESG panes limited groove 13, the groove bottom is formed of multi-layer fire-resistant glass. In this groove an intumescent fire seal 18 is arranged. This is usually complete, so that the groove is continuously provided with the fire seal. Stand, as preferred, the panes on all front sides of the door, the door 4 is frontally around with the fire seal 18 provided. Intumescent fire protection seals are known in the art and are commercially available. For example, a PROMASEAL®-LX fire seal can be provided by Promat AG, Switzerland.
    The solid element 3 is constructed in this example with its layers identical to the door and has in its interior also a multi-layer, clear transparent fire glass 10. In this several glass layers 15 are provided and fire protection layers 16 are provided between the glass layers. All glass layers of the
    Fire protection glass 10 are preferably float glass layers of the same thickness. In the spaces between two such glass layers, the transparent fire protection layers are embedded, which foam in the event of fire and form an opaque heat shield. Such fire protection glasses 10 are, as mentioned, known. A corresponding commercially available fire-resistant glass is known from the manufacturer Schott AG, Germany, under the name PYRANOVA®.
    According to the invention, a single-pane safety glass 11 and 12 is provided on both sides of the fire protection glass 10 over the entire surface, which is laminated directly to the respective outer float glass of the fire protection glass 10. The lamination of glass sheets is, as mentioned, basically known to the person skilled in the art. When laminating glass, at least two sheets of glass are bonded together by means of an adhesive layer. The adhesive layer is usually the aforementioned PVB films or EVA films, with the aid of which laminated glasses can be produced. A tempered safety glass (ESG) is known to consist of a single, specially heat treated disc and must be cut before its heat treatment, since subsequent processing is possible only to a very limited extent. Due to the heat treatment, the ESG washers 11 and 12 have increased impact and impact resistance and are insensitive to large temperature differences.
    According to the invention, the toughened panes 11 and 12 of the fixed element 3 are dimensioned and laminated onto the fire protection glass 10 that protrude at least one end face, but in particular on all faces of the fixed element 3 ESG panes on the fire protection glass and thus form a laterally delimited by the ESG panes groove 13, the groove bottom is formed by the multi-layer fire-resistant glass. In this groove an in-tumescent fire seal 18 is arranged. This is usually complete, so that the groove is continuously provided with the fire seal. If the ESG panes protrude at all end faces of the fixed element 3, as is preferred, then this is provided with the fire protection seal 18 all around. Intumescent fire protection seals are known in the art and are commercially available. For example, a PROMASEAL®-LX fire seal can be provided by Promat AG, Switzerland.
    On the building side conclusion, the solid element is preferably also provided with the groove and the fire seal. The transition from the solid element 3 made of glass to the building part 2 can be carried out in any manner known to those skilled in the art and will not be explained further here. In particular, a profile may be provided for this purpose. As "profileless" the inventive fire-resistant glazing is called because within the glass surface no profile is provided. It may still be a profile provided directly at the transition from the fire-resistant glazing to the building part 2, this is still understood as a profileless in the sense of the present invention. However, the fixed element is also executed randverbundlos the transition to the building part, as described above.
    The other fixed elements 5 and 7 are, if present, preferably also carried out as described for the solid element 3.
