Description

Brandschotten Nach einem eigenen, nicht zum Stande der Technik gehörenden Vorschlag kann man feuerfeste Türen oder Brandschotten dadurch herstellen, daß man innerhalb derselben Brandschutzplatten anordnet, die aus wasserhaltigen Alkalisilikaten bestehen, in denen Fasern eingebettet sindo Die Alkalisilikatplatten sollen einen Wassergehalt von 20 bis 70 Gewichtsprozent, vorzugsweise 40 bis 60 Gewichtsprozent, und einen Fasergehalt von vorzugsweise künstlichen Silikatfasern von 10 bis 40 Gewichtsprozent, vorzugsweise 15 bis 25 Gewichts prozent, bezogen auf wasserfreies Alkalisilikat, enthalten. Fire bulkheads According to their own, not belonging to the state of the art Proposal can be made of fireproof doors or fire bulkheads that one arranged within the same fire protection panels made of hydrous alkali silicates in which fibers are embedded o The alkali silicate panels should have a Water content of 20 to 70 percent by weight, preferably 40 to 60 percent by weight, and a fiber content of preferably artificial silicate fibers of 10 to 40 percent by weight, preferably 15 to 25 percent by weight, based on anhydrous alkali silicate, contain.

Solche Brandsohotten, die im allgemeinen als Falltüren ausgebildet sind und in Rillen geführt werden, haben jedoch noch den Nachteil, daß der bei einem Brand entstehende Zug die Flammen zwischen den Ritzen hindurchzieht und somit einem Umsichgreifen eines Feuers nur ein begrenzter Widerstand entgegengesetzt wird. Die Feuerfestigkeit der Schotte allein ist daher nur von begrenztem Wert, wenn nicht ein Umsichgreifen der Flammen in der beschriebenen Weise verhindert wirdo In Figur 1 ist ein waagrechter Schnitt durch eine Brandschotte wiedergegeben, die die oben aufgeführten Nachteile nicht aufweist. Mit 1 ist eine Brandschotte bezeichnet, die in der Rille 3 geführt wirdo Die Rille selbst und ein Teil der Wand vor und hinter der Brandschotte ist mit zwei Lagen von wasserhaltigen Alkalisilikatplatten, in denen Fasern eingebettet sind, ausgelegt. Im Falle eines Brandes beginnen diese Platten unter Absieden des in ihnen enthaltenen Wassers aufzuschäumen, wodurch die Ritzen zwischen Rille und Schotte praktisch luftdicht verschlossen werden, so daß ein Durchschlagen der Flammen unmöglich gemacht ist. In Figur 2 ist die in Figur 1 veranschaulichte Vorrichtung, bei der die Platten 2 während eines Brandes bereits aufgeschäumt sind, dargestellt.Such fire sooths, which are generally designed as trap doors are and are guided in grooves, but still have the disadvantage that the one Fire arising train pulls the flames through between the cracks and thus one Reaching around there is only limited resistance to a fire. The fire resistance the Scot alone is therefore of limited value, if not a reach the flames is prevented in the manner described o In Figure 1 is a horizontal Section through a firewall showing the disadvantages listed above does not have. 1 with a fire bulkhead, which is guided in the groove 3 willo The groove itself and part of the wall in front of and behind the fire bulkheads is with two layers of water-containing alkali silicate boards in which fibers are embedded are designed. In the event of a fire, these panels begin to boil off the water contained in them foam up, eliminating the cracks between the groove and Bulkheads are closed practically airtight, so that the flames can penetrate is made impossible. In Figure 2 is the device illustrated in Figure 1, in which the plates 2 are already foamed during a fire, shown.

Die Dicke der Platten wird so bemessen, daß die mit ihnen erzielbare Schaumhöhe bei der Einwirkung erhöhter Temperaturen ausreicht, um den freien Raum zwischen Rille und Brandschotte vollständig auszufüllen.The thickness of the plates is dimensioned so that the achievable with them Foam height when exposed to elevated temperatures is sufficient to free space To be filled in completely between the groove and the firewall.
