Abstract
Description
An historischen Decken und Wandkonstruktionen mit Holz- und Strohanteilen sowie an den gezielten Einsatz von Lehm bei der Umhüllung von Balkenköpfen läßt sich sehr deutlich beobachten, daß die pflanzlichen Faserstoffe und Holzbestandteile von trockenem Lehm zum Teil über Jahrhunderte konserviert werden.On historic ceilings and wall structures with wood and straw parts as well the targeted use of clay in the Wrapping beam heads can be very clearly observe that the vegetable Fibers and wood components from dry clay partly over centuries be preserved.
Die Ursache liegt im hygroskopischen Gleichgewicht zwischen Lehm und pflanzlichen Faserstoffen. Es entsteht keine Feuchtewanderung von Lehm zu Holz oder von Holz zu Lehm.The cause is hygroscopic Balance between clay and vegetable Fibrous materials. There is no Moisture migration from clay to wood or from Wood to clay.
Während die historischen Mischungen und Konstruktionen sehr arbeitsaufwändig waren (Stroh-Lehm- Ausfachungen, Wickeldecken, Stakenwände und -decken) und auch das jüngere Strohleichtlehmverfahren aus den 20er Jahren, jetzt häufig wiederverwendet, sehr arbeitsaufwändig ist und sehr lange Trocknungszeiten benötigt (etwa 95% Anmachwasseranteil), ist die Verwendung von Faserstoffen auf Holzbasis die aus modernen Herstellungsprozessen stammen, wesentlich einfacher zu bewerkstelligen.While the historical blends and constructions very labor-intensive goods (straw-clay Infills, changing blankets, Stake walls and ceilings) and also the younger straw light clay process from the 20s, now often reused, very labor intensive is and very long Drying times required (approx 95% mixing water) is the Use of fibrous materials Wood base from modern manufacturing processes originate, essential easier to do.
Der gesamte Wandaufbau ist damit eine Mischung aus Holzfaserstoffen, Holzkonstruktionsanteilen und Lehm, wobei der Lehm in allen Fällen umhüllend wirkt. Gemische aus Holzfasern mit Lehm sind einfach schüttfähig und müssen nicht wie beim Strohleichtlehm gestampft werden. Der Anmachwasseranteil des Mörtelanteils liegt zwischen 15 und 30%, dadurch ist die Trocknung wesentlich kürzer. The entire wall structure is now a mixture of wood fiber, Wood construction parts and clay, the clay has an enveloping effect in all cases. Mixtures of wood fibers with clay are simply pourable and don't have to like be mashed with light straw clay. The mixing water proportion of the mortar proportion is between 15 and 30% drying is much shorter.
Bei der Entwicklung des Holzlehms werden diese Eigenschaften, die sich an historischen Holz/Lehmstoffkombinationen beobachten und beurteilen lassen, kombiniert mit modernen Herstellungsmethoden und Misch- und Fördergeräten, wie sie in der Bautechnik üblich sind.When developing the wood clay these properties that adhere to historical wood / clay combinations observed and judged, combined with modern manufacturing methods and Mixing and conveying devices, as in the Construction technology are common.
Durch eine sorgfältige Zusammensetzung der Sieblinie neben einer Minimierung des notwendigen Bindemittelanteils (fetter Lehm oder Ton bzw. Betonit) läßt sich das Stoffgemisch, ähnlich wie bei Kornaufbau von Betonmischungen sorgfältig einstellen.Through a careful composition the screen line in addition to minimizing the necessary binder content (fat clay or clay or betonite) Mixture of substances, similar to Grain structure of concrete mixes adjust carefully.
Das Material ist günstigerweise bereits in anderen Produktionen und Arbeitsvorgängen der Holzindustrie oder Forst- oder Landwirtschaft vorbereitet und bereits auf eine gut verarbeitbare Größe durch Häcksler und Schnitzler gebracht worden. Es kann sofort am Bau weiterverwendet werden und läßt sich ausgezeichnet umladen und transportieren.The material is convenient already in other productions and operations of the wood industry or forestry or agriculture prepared and already on a well processable Size by chopper and Schnitzler brought. It can be used immediately in construction and can be excellent reload and transport.
Angemischt wird das Material in großformatigen Trommelmischern, wie sie aus der Betontechnologie bekannt sind oder in kleineren baustellenorientierten Trommelmischern per Hand.The material is mixed in large format drum mixers, like they do in concrete technology are known or in smaller construction sites Drum mixers by Hand.
Es können Wandkonstruktionen mit verlorenen Schalungen oder auch mit temporären Verschalungen verwendet werden. Verlorene Schalungen sind Lattenschalungen oder Holzwolleleichtbauplatten links und rechts auf ein Gerüst aufgenagelt. In die so gebildete Kammer wird der Holzlehm dann geschüttet.There can be wall constructions with lost formwork or also with temporary formwork be used. Lost Formwork is slatted formwork or lightweight wooden boards left and right on nailed a scaffold. In the the chamber thus formed becomes the Wood clay then poured.
Sowohl die verlorenen Schalungen wie auch der schiere Holzlehm sind gute Putzuntergründe. Both the lost formwork like the sheer wood clay are good plaster substrates.
Bei all diesen Arbeitsvorgängen lassen sich Arbeitsmittel, Arbeitsmethoden und Kenntnisse aus der normalen Bau- und Betontechnologie verwenden.In all of these operations can work equipment, working methods and knowledge from normal construction and Use concrete technology.
Das verwendete Bindemittel (Lehm, Ton, Bentonit) stammt entweder vom Aushub von Baustellen oder wird gezielt (Bentonit) in möglichst geringen Dosen eingesetzt. Es entsteht ein Recyclingeffekt, da der Aushub aus Baustellen oft auf Kippen verfahren werden muß.The binder used (Clay, clay, bentonite) either from the excavation of construction sites or is targeted (Bentonite) in the lowest possible Cans used. There is a recycling effect because the excavation is out Construction sites often overturned must be followed.
Der Energieverbrauch liegt je nach Herkunft der Holzfasern zwischen 5 und 15 Kilowattstunden/m³ für Aufbereitung und Transport. Der Preis von Holzschnitzeln liegt zwischen 32 und 38 DM/m³. Der vom Lehm liegt 42-48 DM/m³. Der Wärmedämmwert vergleichbar mit Holzwolleleichtbauplatten bei Verwendung des sehr bindefähigen Tonmehls läßt sich noch weiter steigern.The energy consumption lies depending on the origin of the wood fibers between 5 and 15 Kilowatt hours / m³ for Processing and transportation. The price of wood chips is between 32 and 38 DM / m³. The clay is 42-48 DM / m³. The thermal insulation value comparable to Wood wool lightweight panels at Use of the very bindable Clay flour can still go on increase.
λ = 0,18 W/m K-0,12 W/m Kλ = 0.18 W / m K-0.12 W / m K
Wird zu einem späteren Zeitpunkt ein Gebäude, bei dem Holzlehm in Wänden und Decken und Böden verarbeitet ist, abgerissen, so läßt sich das Material durch einfaches Neuanmischen entweder wiederverwenden oder einer Kompostierung zuführen. Damit entsteht kein Entsorgungsproblem wie bei vielen anderen modernen Baustoffen.Will be at a later date a building where Holzlehm in Walls and ceilings and floors processed is torn down, so lets the material by simple Either re-mix or composting respectively. So there is no Disposal problem as with many other modern building materials.
