Description
Die Erfindung betrifft eine Halterung mit zwei parallel zueinander beabstandeten, mittels mindestens zwei Verankerungslaschen an einer raumbegrenzenden Struktur anbringbaren Halteprofilen für eine Brandschutzscheibe, wobei die Verankerungslaschen mit dem einen Halteprofil verschraubt oder verschweißt sind und als Positioniermittel das zweite Halteprofil erfassen. Die Erfindung betrifft ferner eine Brandschutzverglasung zur Vermeidung des Durchtritts von Feuer und Rauch im Brandfall von einem Raum zu einem anderen mit zumindest einer Brandschutzscheibe, die in einer solchen Halterung fixiert ist.The invention relates to a holder with two parallel spaced, attachable by means of at least two anchoring tabs on a raumbegrenzenden structure retaining profiles for a fire protection, wherein the anchoring tabs are screwed or welded to the one holding profile and detect the positioning profile as the second holding profile. The invention further 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 one fire protection pane which is fixed in such a holder.
Zur Halterung von Brandschutzscheiben in einer Brandschutzverglasung ist es bekannt, jede Brandschutzscheibe auf zwei Verglasungsklötze zu stellen und oben und unten durch je zwei Stahlhohlprofile zu halten, die beidseitig der Brandschutzscheibe angeordnet werden. Für den Anschluss der Stahlhohlprofile an Massivbauteile gibt es unterschiedliche Möglichkeiten. So ist die direkte Befestigung der Profile mittels Schrauben und Metalldübeln an der raumbegrenzenden Struktur bekannt. Als nachteilig wird ferner die Sichtbarkeit der Verschraubung angesehen, die darüber hinaus wegen der die Stahlhohlprofile senkrecht durchgreifenden Verschraubung schwierig zu montieren ist und breite Profile erfordert, um überhaupt ein Werkzeug ansetzen zu können. Dabei ist auch die Positionierung und gleichmäßige Ausrichtung der Stahlhohlprofile in den Fällen schwierig, in denen die raumbegrenzende Struktur uneben ist, so dass aufwendige Justierarbeiten erforderlich sind. Zu berücksichtigen ist dabei, dass zur Herstellung einer raumtrennenden Brandschutzverglasung unter Umständen Raumhöhen bis zu 3,50 Meter abgedeckt werden müssen und folglich die Halterungen der Brandschutzscheiben am Boden und an der Decke hohe mechanische Belastungen auf Grund des Gewichts der Brandschutzscheiben und gegebenenfalls eine hohe mechanische horizontale Stoßbelastung aufnehmen müssen und darüber hinaus den Anforderungen des Brandschutzes genügen müssen.
Alternativ zu der beschriebenen Halterung ist eine verbesserte Halterung für eine Brandschutzscheibe bekannt, bei der die zwei parallel zueinander beabstandeten Halteprofile mittels mindestens zwei Querlaschen in Form von Verankerungslaschen an der raumbegrenzenden Struktur anbringbar sind. Dabei sind die Verankerungslaschen mit dem einem Halteprofil verschraubt oder verschweißt und die Befestigung erfolgt am Massivbauteil durch die Verankerungslaschen mit Metalldübeln und Stahlschrauben.
Um die Aufstellung der Brandschutzscheibe zu ermöglichen, erfolgt die Montage des zweiten Stahlhohlprofils erst nach der Positionierung der Brandschutzscheibe auf den Querlaschen, indem zunächst eine Gewindehülse mit Schraubansatz mit jeder Lasche verschraubt wird. Sodann wird das Stahlhohlprofil auf die Gewindehülsen aufgesetzt, wozu entsprechend große Löcher in dem Stahlhohlprofil ausgebildet sind. Schließlich wird das Stahlhohlprofil mittels einer in jede Gewindehülse einschraubbaren Schraube auf jeder Lasche fixiert. Nachteilig ist dabei, dass die Halterung unterschiedlich ausgebildete Stahlhohlprofile aufweist, dass die Befestigungskonstruktion kompliziert ist, die Montage schwierig ist und Fingerspitzengefühl erfordert. Schließlich ist nachteilig, dass die Fixierschrauben für das zweite Stahlhohlprofil sichtbar sind und damit den ästhetischen Gesamteindruck der Verglasung beeinträchtigen.For holding fire protection panels in a fire-resistant glazing, it is known to put each firewall on two glazing blocks and keep up and down by two steel hollow profiles, which are arranged on both sides of the fire protection. There are various possibilities for connecting the hollow steel profiles to solid components. Thus, the direct attachment of the profiles by means of screws and metal dowels on the space-limiting structure is known. Another disadvantage is the visibility of the screw is also considered, which is difficult to install because of the steel hollow sections perpendicular cross-bolting and requires wide profiles in order to start a tool at all. In this case, the positioning and uniform alignment of the hollow steel profiles is difficult in cases where the space-limiting structure is uneven, so that complex adjustments are required. It has to be taken into account that room heights of up to 3.50 meters may have to be covered in order to produce a room-separating fire-resistant glazing, and consequently the holders of the fire-protection windows on the floor and on the ceiling must be subjected to high mechanical loads due to the weight of the fire-resistant windows possibly have to record a high mechanical horizontal impact load and beyond must meet the requirements of fire protection.
As an alternative to the described holder, an improved holder for a fire protection pane is known, in which the two parallel spaced holding profiles can be attached to the space-limiting structure by means of at least two transverse straps in the form of anchoring straps. The anchoring straps are bolted or welded to a retaining profile and the attachment is made on the solid component through the anchoring straps with metal dowels and steel screws.
In order to enable the installation of the fire protection pane, the second steel hollow profile is installed only after the positioning of the fire protection pane on the transverse straps, by first screwing a threaded sleeve with a screw attachment to each tab. Then, the hollow steel profile is placed on the threaded sleeves, including correspondingly large holes are formed in the hollow steel profile. Finally, the steel hollow profile is fixed by means of a screw in each threaded sleeve screw on each tab. The disadvantage here is that the holder has differently designed hollow steel profiles that the mounting structure is complicated, the installation is difficult and requires tact. Finally, it is disadvantageous that the fixing screws for the second hollow steel profile are visible and thus impair the overall aesthetic impression of the glazing.
Die
Der Erfindung liegt die Aufgabe zugrunde, unter Meidung oben genannter Nachteile eine Halterung zu entwickeln, die konstruktiv einfach aufgebaut ist, leicht zu montieren und zu demontieren ist und die Nutzung von im Wesentlichen identischen Halteprofilen ermöglicht, die darüber hinaus sehr schmal ausgebildet sind und eine nach der Montage nicht sichtbare Querverbindung miteinander aufweisen.
Die Aufgabe ist erfindungsgemäß dadurch gelöst, dass mindestens zwei weitere als Verriegelungslaschen ausgebildete, verschwenkbar an einem der beiden Halteprofile angeordnete Laschen vorgesehen sind, die mit dem anderen Halteprofil verriegel- und entriegelbar sind.The
The invention has for its object to develop while avoiding the above-mentioned disadvantages of a holder that is structurally simple, easy to assemble and disassemble and allows the use of substantially identical retaining profiles, which are also very narrow and one after the assembly not visible cross-connection with each other.
The object is inventively achieved in that at least two further designed as locking tabs, pivotally mounted on one of the two Holding profiles arranged tabs are provided which can be locked and unlocked with the other holding profile.
In Abhängigkeit von den Abmessungen der Brandschutzscheibe befinden sich über die Länge der Halterung in abwechselnder Anordnung verteilt mehrere Verankerungslaschen und mehrere Verriegelungslaschen, um eine sichere Fixierung der Brandschutzscheibe in der Halterung sowie am Boden bzw. der Decke des Raumes sicherzustellen, in welchem die Brandschutzverglasung eingesetzt wird.Depending on the dimensions of the fire panel are located over the length of the holder in an alternating arrangement distributed more anchoring tabs and a plurality of locking tabs to ensure secure fixation of the fire protection in the holder and the floor or ceiling of the room in which the fire-resistant glazing is used ,
Vorzugsweise sind die Verriegelungslaschen und Verankerungslaschen an dem gleichen Halteprofil befestigt und befinden sich die Verriegelungslaschen in einem Abstand zu den Verankerungslaschen, der größer ist als der äußere Abstand zwischen den Halteprofilen, um ein Verschwenken der Verriegelungslaschen zur Verriegelung oder Entriegelung mit dem anderen Halteprofil zu ermöglichen. Die Halteprofile selbst sind als schmale Metallhohlprofile rechteckigen Querschnitts, insbesondere aus Stahl, ausgestaltet, wobei die Laschen breiter als die jeweils zugehörige Schmalseite der Halteprofile sind. Hierdurch ist es leicht möglich, jede Verriegelungslasche mit einem Werkzeug zu erfassen und in ihre Verriegelungsstellung zu verschwenken oder eine Entriegelung vorzunehmen.Preferably, the locking tabs and anchoring tabs are secured to the same retaining profile and the locking tabs are spaced from the anchoring tabs greater than the outer spacing between the retaining tabs to permit pivoting of the locking tabs for locking or unlocking with the other retaining profile. The holding profiles themselves are configured as narrow metal hollow profiles of rectangular cross-section, in particular made of steel, wherein the tabs are wider than the respectively associated narrow side of the holding profiles. As a result, it is easily possible to detect each locking tab with a tool and to pivot in its locking position or to make an unlocking.
Die Laschen sind durch in der Verriegelungsstellung im Wesentlichen rechtwinklig an den Halteprofilen angeordnete Metallbleche gebildet, wobei zur Erleichterung der Schwenkbewegung die Stärke der Verriegelungslaschen vorteilhafterweise geringer als die der Verankerungslaschen ist. Die Verriegelung zwischen jeder Verriegelungslasche und dem anderen Halteprofil ist selbsthemmend formschlüssig vorgenommen, wozu vorzugsweise jede Verriegelungslasche mit einer in Schließrichtung offenen Ausnehmung versehen ist, die mit einem an dem anderen Halteprofil angeordneten Vorsprung durch Haftreibung zur Verriegelung zusammenwirkt. Die Ausnehmung kann eine Einlaufschräge aufweisen. Vorzugsweise ist der Vorsprung am anderen Halteprofil in Form einer Stufenschraube ausgebildet, die unter dem Schraubenkopf einen Klemmschaft aufweist, der über eine Abstufung in einen Gewindeansatz geringeren Durchmessers übergeht, welcher mit dem Halteprofil verschraubt ist. In der Verriegelungsstellung der Verriegelungslasche umgreift deren Ausnehmung formschlüssig den Klemmschaft und sichert die Verriegelung über die vorhandene Reibkraft.The tabs are formed by arranged in the locking position substantially at right angles to the support profiles metal sheets, to facilitate the pivoting movement, the strength of the locking tabs is advantageously less than that of the anchoring tabs. The locking between each locking tab and the other retaining profile is made self-locking form-locking, for which purpose preferably each locking tab is provided with a recess open in the closing direction, which cooperates with a arranged on the other holding profile projection by friction for locking. The recess may have an inlet slope. Preferably, the projection on the other retaining profile in the form of a stepped screw is formed, which has a clamping shaft under the screw head, which merges via a gradation in a threaded neck of smaller diameter, which is bolted to the retaining profile. In the locking position of the locking tab engages around the recess positive locking the clamping shaft and secures the lock on the existing friction force.
Ein weiterer Gegenstand der vorliegenden Erfindung betrifft eine Brandschutzverglasung zur Vermeidung des Durchtritts von Feuer und Rauch im Brandfall von einem Raum in einen anderen mit zumindest einer Brandschutzscheibe, die in einer erfindungsgemäßen Halterung fixiert ist. Dabei können im Prinzip sämtliche Arten von Brandschutzscheiben eingesetzt werden, wobei solche bevorzugt werden, die zwei mittels eines Randverbunds parallel voneinander beabstandete Glasscheiben aus Einscheiben-Sicherheitsglas aufweisen, bei denen der vom Randverbund eingeschlossene Raum zwischen den Glasscheiben mit einem Brandschutzgel gefüllt ist. Diese zeichnen sich durch gute Brandresistenzen bei gleichzeitig moderatem Gewicht der Verglasung aus.Another object of the present 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 one fire protection pane which is fixed in a holder according to the invention.
