Description
Die Erfindung betrifft ein Verfahren zum Einbringen eines Wärmedämmstoffes in einen Hohlraum eines Bauwerks nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for introducing a thermal insulation material into a cavity of a building according to the preamble of claim 1.
Bei neueren Bauwerken oder bei der Sanierung von Altbauten ist es üblich gewor den, auch Hohlräume in diesen Bauwerken mit Dämmstoffen auszufüllen, um einen zu großen Wärmeverlust zu verhindern. Oft kann nur hierdurch den amtlichen Wärmeschutzverordnungen entsprochen werden. Besonders häufig werden derartige Wärmedämmungen bei ausgebauten Dächern in die Dachkonstruktion, also zwischen die Dachsparren, die Dachziegel und die Innenverkleidung, eingebaut, jedoch ist ihr Einbau auch in alle anderen außenliegenden Hohlräume von Bauwerken möglich und sinnvoll.It is common in newer buildings or in the renovation of old buildings to fill cavities in these structures with insulation materials in order to to prevent excessive heat loss. Often this is the only way the official Thermal protection regulations are complied with. Such are particularly common Thermal insulation for roofs that have been removed into the roof structure, i.e. between the rafters, the roof tiles and the interior cladding, built in, however, you Installation also possible in all other external cavities in buildings sensible.
Häufig wird die Wärmedämmung in Mattenform angeliefert und, beispielsweise bei einem Dachausbau, vor dem Anbringen der Innenverkleidung zwischen den Dach sparren befestigt. Diese Methode ist jedoch nicht anwendbar, wenn eine Wärmedämmung nachträglich eingebracht werden soll, wenn also bereits eine Innenverkleidung ange bracht ist.The insulation is often supplied in mat form and, for example, at a roof extension, before attaching the interior cladding between the roof rafters attached. However, this method is not applicable when thermal insulation should be introduced later, if an inner lining is already attached is brought.
In den Druckschriften DE 29 02 587 A1, DE 29 12 795 A1 und DE 32 30 614 A1 sind Verfahren zum Einbringen von Wärmedämmungen bei geneigten Dächern be schrieben, bei welchen der Dämmstoff in loser Form vorliegt und in den bereits abge schlossenen Hohlraum eingeblasen wird. Bei diesen Verfahren ist es also möglich, bei bereits verkleideten Dächern nachträglich eine Isolierung vorzunehmen. Als Dämm stoff werden geblähtes, körniges Perlite und Vermiculite vorgeschlagen. Bei Perlite handelt es sich um Mikrohohlkugeln und bei Vermiculite um eine Art Glimmerku geln. Bei den beschriebenen Verfahren rieselt der granulatartige, körnige Dämmstoff nach dem Einblasen in den Hohlraum nach unten und häuft sich mit zunehmender Füllung innerhalb des Hohlraums an. Der Hohlraum kann also nur gefüllt werden, wenn die Einfüllöffnung ganz oben ist; außerdem bleiben schwer zugängliche Ni schen des Hohlraums oft ungefüllt. Schließlich handelt es sich bei den beschriebenen Dämmstoffen Perlite und Vermiculite um künstlich hergestellte und damit teure Materialien.In documents DE 29 02 587 A1, DE 29 12 795 A1 and DE 32 30 614 A1 are procedures for installing thermal insulation on sloping roofs wrote in which the insulation is in loose form and in the already abge closed cavity is blown. With these methods it is therefore possible to Insulate roofs that have already been clad. As a dam Expanded, granular perlite and vermiculite are proposed. At Perlite are hollow microspheres and vermiculite is a kind of mica apply. In the processes described, the granular, granular insulation material trickles after blowing down into the cavity and piling up with increasing Filling inside the cavity. So the cavity can only be filled when the filler opening is at the top; in addition, Ni remains difficult to access cavity often unfilled. Finally, it is the described Perlite and vermiculite insulation materials for artificially manufactured and therefore expensive Materials.
Es besteht daher die Aufgabe, ein Verfahren zum Einbringen eines Dämmstoffes so weiterzubilden, daß auf kostengünstige Weise eine gleichmäßige Füllung der zu isolierenden Hohlräume erreicht wird und der Hohlraum an beliebigen Einfüllorten gefüllt werden kann.There is therefore the task of a method for introducing an insulating material so that in a cost-effective manner, a uniform filling of the insulating cavities is reached and the cavity at any filling location can be filled.
Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This object is achieved with the characterizing features of claim 1. Advantageous refinements can be found in the subclaims.
Ein Ausführungsbeispiel der Erfindung wird im folgenden näher beschrieben.An embodiment of the invention is described in more detail below.
Anstelle der im Stand der Technik bekannten Materialien werden faserartige Mate rialien verwendet, und zwar Naturfasern. In einem bevorzugten Ausführungsbeispiel werden Kokosfasern benutzt, wobei sich in elektronenmikroskopischen Untersuchun gen herausgestellt hat, daß es sich hierbei um Hohlfasern handelt. Vorzugsweise werden nichtgekräuselte, geröstete Kokosfasern benutzt. Weil ihre Fasern hohl sind, ist die Kokosfaser besonders gut wärmeisolierend. Für die Verwendung in dem er findungsgemäßen Verfahren ist ferner von Bedeutung, daß die Kokosfaser an ihrer Außenfläche rauh und gröber strukturiert ist als andere Naturfasern. Schließlich ist die Kokosfaser auch ohne Zusatz von Konservierungsstoffen unverrottbar.Instead of the materials known in the prior art, fibrous mate rialien used, namely natural fibers. In a preferred embodiment coconut fibers are used, whereby in electron microscopic examinations gene has highlighted that these are hollow fibers. Preferably non-crimped, roasted coconut fibers are used. Because their fibers are hollow the coconut fiber is particularly well heat-insulating. For use in the he The inventive method is also important that the coconut fiber at its The outer surface is rough and coarser than other natural fibers. Finally is the coconut fiber rots without the addition of preservatives.
Die Kokosfasern werden in einer Schneidevorrichtung, beispielsweise einer Guillotine oder einem Häcksler auf eine definierte Länge zwischen 2 und 6 mm, vorzugsweise 4 mm geschnitten. Ihr Außendurchmesser liegt unter 1 mm. Sodann werden die geschnittenen Kokosfasern mit einem Brandschutzmittel versehen und auf an sich bekannte Weise in den zu isolierenden Hohlraum eingeblasen.The coconut fibers are in a cutting device, for example a guillotine or a chopper to a defined length between 2 and 6 mm, preferably 4 mm cut. Their outer diameter is less than 1 mm. Then the Cut cut coconut fibers with a fire protection agent and on itself known way blown into the cavity to be isolated.
Zum Einblasen des Fasergemisches in den Hohlraum wird dieser gegebenenfalls an einer geeigneten Stelle geöffnet und ein Schlauch oder Rohr an die Öffnung ange schlossen. Dieser Schlauch führt zu einem Gebläse, welches innerhalb des Schlauches eine Luftströmung in Richtung des Hohlraums erzeugt, in welche das Fasergemisch gegeben wird. Die Aufgabe des Fasergemisches in die Luftströmung kann entwe der durch eine Zellenradschleuse oder - nach dem Prinzip der Wasserstrahlpumpe - durch Ansaugen aus einem Reservoir durch den durch die Luftströmung gebildeten Unterdruck erfolgen.To blow the mixture of fibers into the cavity, the latter is optionally turned on opened in a suitable place and a hose or pipe is attached to the opening closed. This hose leads to a blower which is inside the hose creates an air flow in the direction of the cavity, in which the fiber mixture is given. The task of the fiber mixture in the air flow can be either through a rotary valve or - according to the principle of the water jet pump - by suction from a reservoir through the one formed by the air flow Negative pressure.
Die Zerkleinerung der Kokosfasern auf die gewünschte Länge kann entweder vor der Anlieferung an die Baustelle oder an der Baustelle erfolgen. Falls an der Baustelle zerkleinert wird, ist der Zellenradschleuse bzw. dem Reservoir für das Fasergemisch ein Häcksler zur Erzeugung des Fasergemisches vorgeschaltet.The shredding of the coconut fibers to the desired length can be done either before Delivery to the construction site or to the construction site. If at the construction site is crushed, the cellular wheel sluice or the reservoir for the fiber mixture a chopper upstream to generate the fiber mixture.
Das Einblasen des Fasergemisches in den Hohlraum erfolgt unter einem Überdruck von 10 bis 100 Pa, vorzugsweise bei ca. 30 Pa, und zwar so lange, bis die gewünschte Solldichte in dem Hohlraum erreicht ist, welche zwischen 30 und 100 kg/m³, vor zugsweise im Bereich von 60 kg/m³ liegt. Die Einblasverhältnisse, also die durch die Abmessungen des Hohlraums und die Anbringung des Schlauches an den Hohlraum definierte Einblasgeometrie, die Strömungsgeschwindigkeit, der Schlauchdurchmes ser, die Durchflußmenge der Fasern und gegebenenfalls Druck und Temperatur wer den so gewählt, daß am Schlauchende und innerhalb des Hohlraums eine turbulente Strömung des Luft/Fasergemisches entsteht, wodurch die Fasern in dem Hohlraum verwirbelt werden. Auf diese Weise gelangen die Fasern auch in entlegene Ecken und Nischen des Hohlraums und lagern sich völlig orientierungslos aneinander. Durch die rauhe Oberfläche des verwendeten Kokosfasermaterials verhaken sich die einzel nen Fasern ineinander und bilden eine Art Gerüst bzw. eine Struktur, die sich mit zunehmender Zugabe von Fasern weiter verdichtet.The mixture of fibers is blown into the cavity under an overpressure from 10 to 100 Pa, preferably at about 30 Pa, until the desired one Target density in the cavity is reached, which is between 30 and 100 kg / m³ is preferably in the range of 60 kg / m³. The blowing conditions, that is to say through the Dimensions of the cavity and the attachment of the hose to the cavity Defined injection geometry, the flow rate, the hose diameter water, the flow rate of the fibers and, if appropriate, pressure and temperature chosen so that a turbulent at the end of the hose and inside the cavity Flow of the air / fiber mixture arises, causing the fibers in the cavity to be swirled. In this way, the fibers also reach remote corners and Niches of the cavity and lie against each other completely disoriented. By the rough surface of the coconut fiber material gets caught in the individual fibers into one another and form a kind of framework or structure that increasing addition of fibers further compressed.
Versuche haben ergeben, daß ein Herausnehmen dieser Struktur (nach Eröffnung des Hohlraums) eine verfestigte Platte zu Tage bringt, ohne daß beim Einblasen ein Bindemittel oder Klebstoff verwendet worden wäre. Dies kann durch die turbulente Verwirbelung in Verbindung mit der rauhen Oberfläche der Fasern und die hierdurch bewirkte Strukturbildung erreicht werden.Experiments have shown that removal of this structure (after opening of the cavity) brings a solidified plate to the surface without blowing in Binder or adhesive would have been used. This can be due to the turbulent Swirling in connection with the rough surface of the fibers and the hereby caused structure formation can be achieved.
In alternativen Ausführungsformen können anstelle von Kokosfasern auch andere Naturfasern, insbesondere Flachs-, Hanf- oder Holzfasern verwendet werden. Übli cherweise ist der Durchmesser von Flachs-, Hanf- und Holzfasern größer als der von Kokosfasern und ihre Länge wird auch entsprechend größer gewählt. Das Verhältnis von Länge zu Durchmesser beeinflußt auch das turbulente Verhalten der Strömung und die optimale Verhakung der Fasern ineinander und liegt etwa zwischen 3 und 10.In alternative embodiments, others can be used instead of coconut fibers Natural fibers, especially flax, hemp or wood fibers can be used. Usual The diameter of flax, hemp and wood fibers is larger than that of Coconut fibers and their length are also chosen to be correspondingly larger. The relationship from length to diameter also influences the turbulent behavior of the flow and the optimal interlocking of the fibers in each other and lies between 3 and 10th
In weiteren Varianten des Verfahrens können Fasergemische aus verschiedenen Na turfasern oder aus Natur- und Kunstfasern oder aus Fasern und anderen Isolierma terialien benutzt werden.In further variants of the method, fiber mixtures from different Na door fibers or from natural and synthetic fibers or from fibers and other insulating materials materials are used.
Neben den genannten Vorteilen weist das erfindungsgemäße Verfahren den Vorteil auf, daß die Isolierung im wesentlichen durch Naturstoffe erfolgt, also ein Abriß des isolierten Gebäudes wesentlich weniger Sondermüll erzeugt als bei Gebäuden, welche mit Kunststoffen isoliert sind.In addition to the advantages mentioned, the method according to the invention has the advantage on that the isolation takes place essentially by natural substances, that is, an outline of the Insulated buildings generate much less hazardous waste than buildings, which are insulated with plastics.
