Title
(DE) Feuerwiderstandsfähiges Profilbauteil und Verfahren zu seiner Herstellung
(EN) Fire-resistant building profile and method for producing the same
(FR) Profilé de construction résistant au feu et procédé pour sa fabrication
Abstract
(DE) Das erfindungsgemäße feuerwiderstandsfähiges Profilbauteil (1) dient zur Herstellung von Fenstern, Türen, Wandelementen, Fassaden und dergleichen. Es umfaßt zwei im wesentlichen U-förmige Profilteile, insbesondere aus stranggepreßtem Aluminium, die eine Innentragschale (3) und eine Außentragschale (4) ausbilden und die an ihren freien Schenkelenden (300, 301 bzw. 400, 401) der Schenkel (5) der U-Profile mittels thermisch trennender Isolierstege (6) zu einem eine einzige Hohlkammer (H) umgebenden Verbundprofil (35) verbunden sind. Die Hohlkammer (H) ist mit einer Brandschutzisoliermasse (7) zumindest teilweise ausgefüllt. Der besondere brandschutztechnische Vorteil des erfindungsgemäßen Einkammer-Verbundprofils liegt darin, dass durch die große Hohlkammer (H) sehr viel Brandschutzisoliermasse (7) in das Einkammer-Verbundprofil eingefüllt werden kann, die dadurch einen stabilen isolierenden Block bildet, in dem auch die Eckwinkel und Verbindungsmittel eingebettet sein können. Dies ist im erfindungsgemäßen Umfang bei den bekannten Mehrkammer-Verbundprofilen nicht möglich. Es werden auch verschiedene Herstellungsvarianten des Profilbauteils (1) vorgeschlagen, die u.a. die Verwendung einer mörtelartigen aushärtenden Brandschutzisoliermasse (7), die Verwendung vorgefertigter Isoliermasseteile und die Aussparung ungefüllter Teilkammern (37) in der Hohlkammer (H) vorsehen.
(EN) Fire-resistant profile component comprises two essentially U-shaped profile parts made from extruded aluminum forming an inner supporting shell (3) and an outer supporting shell (4). The profile parts are connected on their free side ends (300, 301, 400, 401) using thermally separating insulating bars (6) to form a composite profile (35) surrounding a single hollow chamber (H). The chamber is filled with a fireproof insulating material. An Independent claim is also included for a window or door containing a frame made from sections of the profile parts. Preferred Features: The free side ends of the inner and outer supporting shells have an undercutting groove (302, 402) into which the insulating rods are inserted using a static composite profile. The fireproof insulating material contains magnesium oxychloride cement having a composition with molar ratios of MgCl2/Mg(OH)2/H2O of (2.5-5):(8-12) (sic), produced from a mixture of magnesium oxide and concentrated, especially saturated or over-saturated, aqueous magnesium chloride solution.
