Description

The invention relates to a fire-resistant glazing to prevent the passage of fire and smoke in case of fire from one room to another with at least two existing fire panels and juxtaposed glass surfaces, one of which has a glass door, while the other glass surface to a lateral fixed element (5) and the surface adjacent to the glass door (3) on the opposite side forms a stop element (6).

Various types of space-separating fire-resistant glazings are known from the prior art. The DE 3508078 (A1 ) describes a fire-resistant glazing with a holder for fire protection glass, in which the individual panes are held by a frame surrounding the abutting edges of the fire protection pane. In this structure, it is sometimes considered disadvantageous that no frameless structure for fire-resistant glazing can be realized. In particular, when movable elements such as doors or windows are to be integrated into the glazing, the multiplicity of frame parts to be used for this purpose can impair the visual appearance and also reduce the passage of light.

The German utility model DE 29819678 (U1 ) introduces a fire-resistant glazing in which the vertical joints of the fire-resistant panes are filled with a sealant. This fire wall element also has a window which is installed by means of a frame and a frame in the fire wall element. Even with this solution, it may be considered disadvantageous that closable Openings can not be frameless, which reduces the passage of light through the glazing.

In the European patent application EP 0 658 677 A1 a frameless fire-resistant glazing is described in which fire protection panels are attached to a freestanding support structure. The individual fire protection panels are fixed in this solution by means of brackets, in which on the two sides of the fire protection plate corresponding support plates are provided, which are connected by means of a run through the fire panel screwed together and hold in this way the interposed fire protection disc in the press fit.

A generic glazing is from the European patent EP 1 566 514 B1 known. Therein, a fire-resistant glazing is disclosed with a plurality of juxtaposed glass surfaces, which are held at its upper and / or lower edge by a wooden profile. The glass surfaces are formed by profile filters directly juxtaposed fire protection discs, with adjacent fire panels are held both at their horizontal and at their vertical butt joints solely by a sealant. The glazing also has in at least one of the glass surfaces of a wooden profiles existing frame for a single or multi-leaf door or a window. This frame is held at its edges exclusively by the adjacent fire protection panels. Such an arrangement already allows a significantly improved passage of light compared to the previously described solutions and is sufficiently stable and fireproof. Nevertheless, even with this arrangement can not be completely dispensed wooden profiles.

The object of the present invention is to further increase the passage of light in a glazing of the type mentioned. The glazing should still have good fire protection properties and smoke-tightness and a high degree of stability.

The object of the invention is achieved by a fire-resistant glazing to prevent the passage of fire and smoke in case of fire from one room to another with at least two existing fire panels and juxtaposed glass surfaces, one of which has a glass door, the glass door profile free immediately at least partially the lateral fixed element is pivotally held. The glass door can also be designed as a swing door.

In other words, completely omitted in the glass surface profiles or frames made of wood or metal in the fire-resistant glazing invention. The glazing is characterized not only by a particularly high light transmission, but it also looks visually light and attractive due to the all-glass construction, because you see her the fire protection properties less than in the previously known solutions. The space between the abutting edges of adjacent fixed fire panels is typically filled with a silicone compound or fire protection compound.

Preferably, the fire protection panes used according to the invention are those which have two refractory glass panes spaced apart in parallel from one another by means of an edge seal. The enclosed space between the refractory glass panes is filled with a fire protection gel.

Fire protection windows of the aforementioned type are known in principle. For such fire panes all types of glass panes come into question. However, at least one of the glass panes preferably consists of safety glass, in particular single-pane safety glass or laminated safety glass. This is particularly advantageous because it shatters into very many small fragments at extremely high temperatures in the event of fire, of which on the one hand a lower risk of injury emanates and on the other well in the crushed state adhere well to the fire protection gel and thus continue the fire protection gel for a certain time before protect the direct flame contact. Since toughened safety glass can not be cut after tempering, the recesses for attachment must be cut of hinges, locks and the like are already provided before biasing in the glass sheets. According to the invention, however, also other glass panes can be used, such as float glass.

The glass panes can independently of one another have a pane thickness of 3 to 20 mm, preferably 5 to 10 mm. The distance of the glass sheets may preferably be in the range of 5 to 50 mm. Particularly preferably, the distance of the glass panes from each other is about 8 to 30 mm, as can be achieved in this way, especially with filled fire protection gel fireproof glazings good fire resistance at the same time moderate weight of the glazing.

The space between the panes of glass is filled with a special fire protection gel in the case of gel-filled fire protection windows. With fire protection gel or hydrogel filled fire protection panels are for example in the EP 1 820 931 A1 and in the DE 10 2005 018 842 A1 described. These fire panels have the advantage that they can achieve a lower basis weight with comparable fire resistance class compared to the otherwise often used fire protection with solid silicate-containing intumescent intermediate layers, for example on a water glass basis. This not only means easier transport of the discs, but also that the bracket and frame construction can be made lighter because of the lower load.

Furthermore, the fire protection panels filled with fire protection gel are far less susceptible to penetrating moisture compared to the disks with solid silicate-containing intumescent intermediate layers, which in the latter leads to turbidity of the intermediate layer, which requires replacement of the pane.

Fire protection panels filled with a fire protection gel preferably consist of two parallel-spaced glass panes of toughened safety glass (ESG), which are fixed and connected to one another via a peripheral spacer profile lying in their edge areas between the glass panes and, for example, a polyurethane edge seal. Through an opening in this inwardly offset spacer profile the fire protection gel or the precomponents are filled in the latter case, the gelation is carried out by polymerization to hydrogel in filled with the mixture cavity between the glass sheets. The fire protection gels used in the context of the invention may also contain additives such as silicates, UV protectants or even dyes.

In the context of the present invention, furthermore, the inner glass surface can have an upper solid element, which is arranged above the glass door. The glass door can also be designed as a swing door.

In a further preferred manner, in the present invention, the edge bond of the glass door and the edge seal of the fire protection discs, in particular in the region of the abutting edges immediately adjacent to the glass door, offset inwardly to form a groove, in particular by at least 2 mm, preferably at least 15 mm. This makes it possible to accommodate in the created by the inward displacement of the edge seal groove further improving the fire protection elements and / or sealing elements. This has an advantageous effect on the smoke and flameproofness in the region of the glass door.

For example, in this groove, a strip of an intumescent material and / or a silicate material may be used, wherein the outer surface of the siliceous material is provided in particular with an intumescent material. In the context of the present invention, a siliceous material is typically understood to mean fire protection boards used in the field of fire protection and the like, or the material from which fire protection boards are typically constructed. Intumescent sealing strips are also familiar to the skilled person from the prior art.

In a further preferred manner, the strip of intumescent and / or silicate material used in the groove of the glass door facing the lateral fixed element has on its outside a rounded or semicircular cross section. The glass door according to the invention can be configured as a swing door, wherein the Swivel axis can be shifted in the door leaf. The rounded or semicircular abutting edge of the intumescent and / or siliceous material improves the reliability of the seal in this region of the glass door, in particular in such an embodiment of the glass door.

The glass door can be mounted pivotably in the upper region by means of an upper corner bearing. It is particularly preferred if the upper corner bearing is attached to the upper fixed element and / or the lateral fixed element. In particular, when mounted on both fixed elements increases the stability of the overall construction, since the corner bearing then acts simultaneously as a connection between the two fixed elements and this fixed stronger together.

As far as the lower mounting of the glass door is concerned, it may be pivotably mounted in the lower area by means of a lower corner bearing, in particular by means of a pivot bearing. The pivot bearing may be further preferably designed as a bottom door closer, which may further be configured as an automatic closing device which supports either electrically and / or mechanically the closing movement of the glass door.

According to a particularly preferred embodiment of the fire-resistant glazing according to the invention, the glass door has a glass cutout in the attachment area of the upper and / or lower corner bearing. This is already provided in the case of gel-filled fire protection panes during their production, since the glass cut-out must be taken into account during the attachment of the edge seal.

In the context of the present invention may further be provided that the pivot axis of the glass door extends through the door leaf of the glass door. In other words, therefore, the upper and lower corner bearings are arranged above or below the door leaf.

So that the glass door has a fixed closing point, the glass door can on its side opposite the lateral fixed element one in a glass cutout the glass door attached lock case with a particular centrally arranged lock, for example, a pendulum lock, the pendulum lock in particular comprises a force-loaded with a spring ball or roller.

Corresponding to this, the glass surface adjoining the glass door on the side opposite the lateral fixed element is expediently designed to be stationary as a stand element, this standing element having on its side facing the glass door a stop box which is mounted in a glass cutout of the stand element, wherein the stop box is via a strike plate which is positioned at a height corresponding to the lock.

The strike plate can in principle have any shape which ensures the corresponding operation. Thus, the strike plate may have a rounded, semicircular or crescent-shaped cross section and be provided on the inside in particular with an intumescent material.

To improve the tightness, especially against smoke but also against flame, the lateral and upper abutting edges of the glass door and adjacent to the glass door fire protection windows can be provided in particular made of rubber or plastic seals or sealing strips. These are mounted so that the attached to the glass door seals cooperate with those of the fire-resistant smoke-sealing.

In Fig. 1 a fire protection glazing 1 according to the invention to prevent the passage of fire and smoke in case of fire from one room to another in the plan view is shown. The fire-resistant glazing 1 has three glass panels A-C consisting of fire-resistant windows 2 and arranged side by side, wherein in the inner glass surface B a glass door 3 is provided above the upper fixed element 4 is arranged from a fire protection pane 2. On the right side of the glass door 3 is a side fixed element 5 and on the left side a stand element 6 is provided. The lateral fixed element 5 and the standing element 6 extend over the entire height of the respective glass surfaces A, C. Between the abutting edges of fixed fire protection panels 2, a silicone compound is introduced, which will be explained in more detail below.

The glass door 3 is formed as a swing door and held by an upper corner bearing 7 on the upper fixed element 4 and the fire protection pane 2 of the lateral fixed element 5 directly and pivotally. In this way, the upper corner bearing 7 also fixes the upper fixed element 4 and the lateral fixed element 5 in addition to each other. The axis of rotation D of the glass door 3 extends through the door leaf, so it is slightly offset from the edge to the inside.

The glass door 3 is further kept pivotable by means of a designed as a bottom door closer 8 lower corner bearing. The fire-resistant glazing 1 thus has neither a profile arranged in the glass surfaces A-C nor a frame for the glass door 3.

To increase the stability between the glass surface A and the upper solid element 4 of the glass surface B, a corner holder 9 is provided. The corner holder 4 is composed of two flat angles, which are fixed on both sides by means of guided by the fire panels screwed together.

The enclosed by the glass sheets 2 a, 2 b and the edge seal 10 space is filled with a fire protection gel 11. The glass sheets 2a, 2b are each 8 mm thick wherein the distance of the inner surfaces from each other is 28 mm. The thickness of the fire protection pane 2 is measured 44 mm from outer surface to outer surface.

The fire protection gel 11 is prepared for example as a hydrogel from a NaCl / MgCl ₂ salt solution with the addition of polymerizable compounds such as a mixture of acrylamide, N-methylolacrylamide, methylenebisacrylamide and a polymerization accelerator in water either before filling between the glass sheets _{2 a, 2} b or in-situ the glass sheets 2a, 2b produced by the above-mentioned components are mixed together and filled directly into the cavity between the glass sheets 2a, 2b. The polymerization to the hydrogel then takes place in the cavity now filled with the mixture between the glass panes 2a, 2b.

Between the abutting edges of two adjacent glass sheets 2 a, 2 b joints are formed, which are filled with a silicone compound 12. In the area between the edge bonds 10 of two adjacent fire protection panels 2, a strip 13 of an insulating material is used.

In Fig. 3a is a horizontal section H2 through the fire-resistant glazing 1 in the in Fig. 1 according to marked point in the area of the upper corner bearing 7 to see. The fire protection pane 2 of the glass door 3 has a glass cutout 14 in the attachment area of the upper corner bearing 7. The upper corner bearing 7 is composed of two flat fastening elements 15, 16, which are placed on both sides of the fire protection pane 2 and fastened by means of guided by the fire panel 2 connecting elements 17 to each other. Between the fastening elements 15, 16, a material 18 is provided in the region of the glass section 14, which largely completely fills the region of the glass section 14.
