Description
Die Erfindung betrifft ein als "Sandwichelement" ausgebildetes, dünnwandiges Schall- und Feuerschutzelement, bestehend aus einem äußeren Mantel und einem zwischen den Mantelteilen zur Aufnahme von Feuerschutzmittel dienenden Hohlraum, der durch Distanzelemente bestimmt ist.The invention relates to a thin-walled acoustic and formed as a "sandwich element" Fire protection element, consisting of an outer jacket and one between the Sheath parts for receiving fire-retardant cavity through Distance elements is determined.
Im modernen Bauwesen sind unter anderem zwei wichtige Bereiche von großer Bedeutung. Dies ist einmal der Feuerschutz und andererseits der Lärmschutz.There are two important ones in modern construction Areas of great importance. This is the one time Fire protection and on the other hand noise protection.
Neben den aktiven Einrichtungen wie Sprinkleranlagen etc. sind auch die passiven Feuerschutzmaßnahmen von Bedeutung. Insbesondere feuerhemmende oder feuerbeständige Bauteile nach DIN 4102 sind zu beachten. Das heißt, es sind nicht nur feuerbeständige Bauteile aus nicht brennbaren Baustoffen anzuwenden, sondern auch feuerhemmende Bauteile. Ein wichtiger Bereich ist hierbei der Einsatz von feuerhemmenden oder feuerschützenden Türen oder Wänden. Je nach Beständigkeit werden diese als feuerhemmend oder feuerbeständig oder hochfeuerbeständig klassifiziert.In addition to the active facilities such as sprinkler systems etc. passive fire protection measures are also important. In particular fire-retardant or fire-resistant components according to DIN 4102 must be observed. That said, it's not just that fire-resistant components made of non-combustible building materials but also fire-retardant components. On important area is the use of fire retardant or fire protection doors or walls. Depending on These are called fire retardant or resistance classified fire-resistant or highly fire-resistant.
Ein weiteres wichtiges Gebiet ist der Schallschutz in Gebäuden.Another important area is sound insulation in Buildings.
Der Schallschutz, allgemein als Lärmschutz bezeichnet, wird in der DIN 4109 bzw. 4110 behandelt.Sound insulation, commonly referred to as noise protection, is treated in DIN 4109 and 4110.
Der Lärmschutz bzw. der Schallschutz umfaßt alle Maßnahmen zur Verhinderung oder Verminderung störenden Schalles durch technische Verbesserungen in der Bautechnik.Noise protection or noise protection includes all measures to prevent or reduce disturbing sound technical improvements in construction technology.
Herkömmlicherweise werden diese Maßnahmen oft durch den Einsatz von schweren oder mehrschaligen Konstruktionen getroffen, wobei sich z. B. schallharte und schallweiche Stoffe abwechseln und durch Verwendung von Baustoffen mit bestimmten physikalischen Eigenschaften versucht wird störende Einflüsse zu mindern. Traditionally, these measures are often implemented by the Use of heavy or multi-layer constructions met, z. B. reverberant and reverberant Alternate fabrics and by using building materials certain physical properties is tried reduce disruptive influences.
Allgemein ist im Bauwesen zu beachten, daß dem Schutz von Personen und Lebewesen vor übermäßigem Lärm in allen Lebensbereichen zunehmend mehr Bedeutung beigemessen wird, da die Auswirkungen von Lärmbelästigungen (Streßreaktionen, Schwerhörigkeit etc.) die Gesundheit und das Wohlbefinden, sowie die Arbeitsleistung der Menschen stark beeinträchtigen können.In general, it should be noted in construction that the protection of People and living beings from excessive noise in all Areas of life are becoming increasingly important, because the effects of noise pollution (stress reactions, Hearing loss etc.) health and well-being, and severely affect people's work performance can.
Feuerschutz im engeren Sinne behandelt die Erhöhung der Feuerwiderstandsfähigkeit von Baustoffen und Bauteilen durch Maßnahmen vorwiegend baulicher Art. Diese beginnen bei der Baustoffauswahl. Zu dem Begriff feuerhemmend gehören unter anderem die Feuerwiderstandsklasse F 30 mit einer Feuerwiderstandsdauer von mindestens 30 Minuten und F 60 von mindestens 60 Minuten. Unter anderem gehören hierzu raumabschließende Bauteile, die entsprechend den Vorgabezeiten den Durchgang des Feuers verhindern und dabei auf der dem Feuer abgekehrten Seite keine entzündlichen Gase entwickeln und sich dort im Mittel um nicht mehr als 140°C über der Anfangstemperatur des Prüfkörpers bei Versuchsbeginn erwärmen. Eine weitere Bedingung ist, daß die tragenden Bauteile unter ihrer rechnerisch zulässigen Gebrauchslast, nicht tragende Bauteile unter ihrer Eigenlast, während der Prüfzeit nicht zusammenbrechen dürfen.Fire protection in the narrower sense deals with increasing the Fire resistance of building materials and components through Measures mainly of a structural nature. These start with the Selection of building materials. The term fire retardant include under among others the fire resistance class F 30 with a Fire resistance of at least 30 minutes and F 60 from at least 60 minutes. These include, among others room-sealing components that correspond to the Pre-set times prevent the passage of fire while doing so no flammable gases on the side facing away from the fire develop and there on average by no more than 140 ° C above the starting temperature of the test specimen at Warm up the start of the experiment. Another condition is that the load-bearing components below their arithmetically permissible Working load, non-loadbearing components under their Own load, do not collapse during the test period allowed to.
All diese und noch weitere hier nicht genannten Bedingungen konnten bisher mit den Forderungen des Schallschutzes nicht in Einklang gebracht werden.All of these and other conditions not mentioned here have so far not been able to meet the requirements of sound insulation be reconciled.
Es ist somit bisher nicht zufriedenstellend gelungen eine Kombination eines Schallschutzes und Feuerschutzes/-hemmung zu schaffen, die beiden Anforderungsbereichen gerecht wird. Dieses Ziel wurde bei der Optimierung des Schallschutzes bisher nur auf Kosten des Feuerschutzes bzw. die Optimierung des Feuerschutzes nur auf Kosten des Schallschutzes erreicht. So far, one has not been satisfactorily successful Combination of sound insulation and fire protection / inhibition to create that meets both requirements. This goal was in the optimization of sound insulation so far only at the expense of fire protection or optimization fire protection only at the expense of sound insulation reached.
Aus der DE-A-36 22 897 ist ein kombiniertes Brand- und Schallschutzelement bekannt, das aus separaten Brand- und Schallschutzbahnen aufgebaut ist, die in einer nicht brennbaren Umhüllung mit Abstand voneinander angeordnet sind. Die Brandschutzbahnen bestehen aus einer Intumeszenzmasse, die sich im Brandfall infolge der Hitzeeinwirkung aufbläht, dabei Sauerstoff verbraucht und infolgedessen die Flammenbildung hemmt bzw. unterbindet. Dieses bekannte Brand- und Schallschutzelement hat den Nachteil, daß die Intumeszenzmasse zum einen selbst brennbar ist und zum anderen relativ viel Raum zum Aufblähen benötigt.A combined fire and soundproofing element is known from DE-A-36 22 897, which is made up of separate fire and sound insulation sheets, which are not in one flammable envelope are spaced apart. The fire protection tracks consist of an intumescent mass, which in the event of fire due to the effects of heat inflates, thereby consuming oxygen and consequently inhibiting or prevents. This known fire and soundproofing element has the disadvantage that the Intumescent mass is on the one hand flammable and on the other hand a relatively large amount of space for Bloat needed.
In der DE-A-39 07 604 ist eine Beschichtungsmasse zur Schalldämpfung, insbesondere zur Verminderung der Schallabstrahlung von Blechteilen an Automobilen und Haushaltsgeräten beschrieben, die einerseits schwer entflammbar ist und andererseits eine hohe Beständigkeit gegenüber Rißbildung aufweist. Die schwere Entflammbarkeit ist ein grundsätzliches Erfordernis, um den sicherheitstechnischen Vorschriften zu genügen. DE-A-39 07 604 describes a coating composition for sound absorption, in particular for Reduction of the sound radiation from sheet metal parts on automobiles and household appliances described, which is flame retardant on the one hand and high resistance on the other hand exhibits cracking. The flame retardancy is a basic one Requirement to meet the safety regulations.
Bei den bekannten Vorschlägen konnte eine Stabilität, bei geringer Dicke und geringem Gewicht des Elementes bisher nicht erreicht werden.In the case of the known proposals, stability, at small thickness and light weight of the element so far cannot be reached.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde die Nachteile der Feuerschutz bzw. Lärmschutzelemente des Standes der Technik zu eliminieren und ein kombiniertes, als "Sandwichelement" ausgebildetes, dünnwandiges Schall- und Feuerschutzelement zu schaffen, das eine hohe Stabilität aufweist, eine geringe Dicke besitzt und nur geringes Gewicht hat, und das insbesondere auch als Tür verwendet werden kann, wobei eine Intumeszenzwirkung nicht notwendig ist.The present invention is therefore based on the object the disadvantages of fire protection or noise protection elements of the Eliminate state of the art and a combined, than "Sandwich element" trained, thin-walled sound and Fire protection element to create a high stability has a small thickness and only small Has weight, and which can also be used in particular as a door, one Intumescent effect is not necessary.
Diese Aufgaben werden erfindungsgemäß durch ein kombiniertes, als "Sandwichelement" ausgebildetes, dünnwandiges Schall- und Feuerschutzelement gemäß des vorgeschlagenen Anspruchs 1 gelöst.According to the invention, these tasks are accomplished by a combined, designed as a "sandwich element", thin-walled sound and fire protection element according to the proposed claim 1 solved.
