摘要:
The present invention relates to a smoke or fire barrier (1, figure 1) for closing an opening (6, figure 1) in a building with a means for reducing the flow of smoke past the sides of the barrier. The barrier comprises a curtain (2, figure 1) for closing the opening; a means arrangeable at a head (4, figure 1) of the opening for deploying and retracting the curtain; and a guide (17, figure 1) means at sides of the opening for retaining edges of the curtain after deployment and for reducing flow of smoke past the edges of the curtain. The guide means comprises a pair of jaws or side plates 18, 20 for holding the edges of the deployed curtain, wherein upon activation at least one of the jaws 20 is movable towards the other 18. The mechanism is activated electrically by means of a switch that may be disposed towards the lower end of the guide means so that the switch may be triggered by the deployed fire curtain. A means for moving the or each movable jaw after deployment of the curtain and a door for covering the guide means when not in use are also included.

Eine Seitenführung (20) für einen Brandschutzverschluss (2), wie einen Feuer- bzw. Brandschutzvorhang (4), weist mindestens eine Führungsschiene (22) auf. Die Seitenführung (20) ermöglicht eine Bewegbarkeit des Brandschutzverschlusses (2) entlang der Führungsschiene (22). Die Seitenführung (20) umfasst zumindest ein Bauteil aus Holz. Ein mindestens vierseitig begrenzter Führungskanal (30) ist als Teil der Führungsschiene (22) vorhanden. Der Führungskanal ist für eine Aufnahme mindestens eines auf einer Oberfläche der Führungsschiene (22) bewegbaren und mit dem Brandschutzverschluss (2) verbundenen Führungselements (32, 33) gestaltet. Für einen Brandschutzverschluss (2) ist ein Brandschutzvorhang (4) zumindest zweiseitig von zumindest einer entsprechenden Seitenführung (20) geführt. An mindestens einer Vorhangseite (6) sind Führungselemente (32, 33) vorhanden, die die Führung des Brandschutzvorhangs (4) entlang mindestens einer Führungsschiene erleichtern.

Die Erfindung betrifft ein Brandschutzelement (10), insbesondere für einen Brand- oder Rauchschutzvorhang, mit einem flexiblen Träger (14) und Kühl-Material (18), das auf dem Träger (14) aufgebracht ist und oberhalb einer Aktivierungstemperatur unter Wärmeaufnahme reagiert. Erfindungsgemäß ist ein organischer Binder (16) vorgesehen, mittels dem das Kühl-Material (18) mit dem flexiblen Träger (14) verbunden ist, sodass das Brandschutzelement (10) flexibel ist.
摘要:
A smoke or fire protection device to seal an opening (12) comprising a flexible protection member (106) that can be put in a protection arrangement in which the protection element (106) counteracts the spread of smoke and/or fire through the opening (12), and can be put in a storage arrangement in which the opening (102) is unsealed, wherein the protection element (106) only comprises metal foil or metal foil and a wire mesh.

Curtain draw back system for an emergency exit (30) comprising at least one exit element (32) that can be opened in case of an emergency, wherein the curtain draw back system (1) comprises a rail (10) configured to displaceably hold a covering (28) such as a curtain, wherein the curtain draw back system (1) comprises a draw back assembly (2) coupled to the rail, which draw back assembly is configured to withdraw the covering along the rail in dependence of a withdraw signal such that the at least one exit element will be freely accessible. The invention further relates to an assembly comprising an emergency exit and a curtain draw back system and to a method to adapt a curtain rail into a curtain draw back system.
摘要:
A multilayer interlayer polymer film for use within and a high clarity and high efficiency fire-screen glazing or related fire-screen product uses a particular ordering of layers. The particular ordering of layers includes: (1) a core layer comprising one of a sulfur containing thermoplastic polymer material and a fluorine containing thermoplastic polymer material; (2) at least one intermediate layer laminated to the core layer and comprising the other of the sulfur containing thermoplastic polymer material and the fluorine containing thermoplastic polymer material; and (3) at least one skin layer laminated to the at least one intermediate layer and comprising a thermoplastic polyurethane material. The multilayer interlayer polymer film provides cost effective and efficient fire-screen glazings and related fire-screen products due to use of the thermoplastic polyurethane polymer material and the sulfur containing thermoplastic polymer materials which also may be used in absence of the fluorine containing thermoplastic polymer material to provide an additional embodiment.
