Description

Die Erfindung betrifft eine Wand für ein Holzhaus mit einer äußeren Schicht aus Holz und einer inneren Schicht und einer aus Spänen bestehenden Isolierung im Zwischenraum zwischen der äußeren und der inneren Schicht. Die Erfindung betrifft weiter ein Verfahren zur Herstellung einer derartigen Wand.The invention relates to a wall for a wooden house with an outer layer of wood and an inner layer and an insulation consisting of chips in the space between the outer and the inner layer. The invention further relates to a method for producing such a wall.

Es sind Wände oder Wandteile bekannt (Siehe z.B. die DE-A-3 625 405), die Teil eines Holzhauses sind. Derartige Wände oder Wandteile bestehen in der Regel aus einer äußeren Holzschicht, die beispielsweise aus einzelnen Balken oder Brettern aufgebaut ist. Die einzelnen Balken oder Bretter der Holzschicht sind in der Regel mit einer Nut- und Federverbindung untereinander verbunden. Die innere Schicht kann in gleicher Weise aufgebaut sein. Sie besteht in der Regel aus Nut- und Federbrettern oder einem anderen, plattenartigen Material. Die innere und äußere Schicht einer solchen Wand sind durch Distanzelemente, beispielsweise durch Balken verbunden, so daß sich zwischen den beiden Schichten ein Zwischenraum ergibt, der eine Isolierung aufzunehmen hat.Walls or wall parts are known (see, for example, DE-A-3 625 405), which are part of a wooden house. Such walls or wall parts usually consist of an outer layer of wood, which is made up of individual beams or boards, for example. The individual beams or boards of the wood layer are usually connected to each other with a tongue and groove connection. The inner layer can be constructed in the same way. It usually consists of tongue and groove boards or another plate-like material. The inner and outer layers of such a wall are connected by spacing elements, for example by beams, so that there is an intermediate space between the two layers which has to accommodate insulation.

Es ist bekannt, als Isolierung Späne, insbesondere Hobelspäne zu verwenden. Auch andere Arten von Isolierungen, beispielsweise Steinwolle, Glaswolle, Polystyrol oder ähnliche Mittel sind bekannt.It is known to use shavings, in particular shavings, as insulation. Other types of insulation, for example rock wool, glass wool, polystyrene or similar agents, are also known.

Eine Wand der beschriebenen Gattung hat den Vorteil, daß die Wand, wenn gewünscht, werkstattmäßig gefertigt werden kann. Unbefriedigend ist jedoch die Isolationswirkung. Bei geeignetem Isolationsmaterial, das vorzugsweise aus Platten besteht und aufwendig einzupassen ist, lassen sich wohl gute Wärmeisolationswerte erzielen. Die Schallisolation ist jedoch mangelhaft. Werden Späne als Isolationsmaterial benützt, beispielsweise Hobelspäne oder Späne anderer Herkunft, wird zwar der Vorteil erhalten, daß das Isolationsmaterial nur einen geringen Wert besitzt. Der Nachteil ist jedoch die leichte Entflammbarkeit bzw. die schlechte Dämmwirkung im Falle eines Brandes. Zwar ist es möglich, durch brandhemmende Zusatzstoffe die Feuerhemmung etwas zu verbessern. Wegen der sehr großen Oberfläche bzw. den geringen Abmessungen von Spänen ist jedoch der Verbrauch an derartigen Mitteln beträchtlich.A wall of the type described has the advantage that the wall can, if desired, be made in the workshop. However, the insulation effect is unsatisfactory. With suitable insulation material, which preferably consists of plates and is difficult to fit, good thermal insulation values can be achieved. However, the sound insulation is poor. If chips are used as insulation material, for example shavings or chips of other origin, the advantage is obtained that the insulation material has only a low value. The disadvantage, however, is the easy flammability or the poor insulation in the event of a fire. It is possible to improve fire retardancy somewhat by using fire retardant additives. However, because of the very large surface area and the small dimensions of chips, the consumption of such agents is considerable.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Wand der eingangs angegebenen Gattung eine Isolierung vorzusehen, die bei geringem Herstellungsaufwand gute Schall- und Wärmeisolationseigenschaften aufweist und die auch einen wesentlich besseren Brandschutz ergibt.The invention has for its object to provide insulation for a wall of the type specified above, which has good sound and heat insulation properties with low manufacturing costs and which also results in significantly better fire protection.

Zur Lösung dieser Aufgabe geht die Erfindung aus von einer Wand der eingang angegebenen Gattung. Erfindungsgemäß wird vorgeschlagen, daß die Isolierung aus mehreren aneinander anliegenden Schichten besteht, und zwar mindestens aus einer ersten, Bindemittel aufweisenden Schicht und mindestens aus einer zweiten Schicht aus gestopften Spänen, wobei die beiden Schichten, die einzeln keine oder nur geringe Stabilität aufweisen, in der Wand sich gegenseitig abstützen.To achieve this object, the invention is based on a wall the genus specified at the beginning. According to the invention, it is proposed that the insulation consist of several adjacent layers, namely at least one first layer containing binder and at least one second layer of stuffed chips, the two layers, which individually have no or only little stability, in the Wall support each other.

Dadurch, daß die Erfindung mindestens zwei Schichten vorsieht, wird eine vorteilhafte Ergänzung der Wirkung der beiden Schichten erreicht. Insbesondere wird der Vorteil erhalten, daß die beiden Schichten sich gegenseitig abstützen, so daß die mechanische Festigkeit insbesondere auch der ersten Schicht gering sein kann. Diese erste Schicht, die beispielsweise eine Mörtelschicht sein kann, verbessert wesentlich die feuerhemmende Wirkung. Die erste Schicht deckt dabei entweder die Späneschicht ab oder verhindert im Brandfall eine Ausbreitung eines Brandherdes über die Späneschicht hinaus. Selbstverständlich können zusätzlich noch feuerhemmende Mittel wie Alu-Hydroxid, Phosphate und ähnlich wirkende Stoffe angewandt werden.Because the invention provides at least two layers, an advantageous addition to the effect of the two layers is achieved. In particular, the advantage is obtained that the two layers support one another, so that the mechanical strength, especially of the first layer, can be low. This first layer, which can be a layer of mortar, for example, significantly improves the fire-retardant effect. The first layer either covers the chip layer or prevents a fire from spreading beyond the chip layer in the event of a fire. Of course, fire retardants such as aluminum hydroxide, phosphates and similar substances can also be used.

Die erste Schicht wird von der zweiten Schicht fixiert, wobei entweder diese erste Schicht zwischen zwei Schichten aus gestopften Spänen angeordnet sein kann oder zwischen einer Späneschicht einerseits und einer der äußeren oder inneren Wandschichten andererseits.The first layer is fixed by the second layer, wherein either this first layer can be arranged between two layers of stuffed chips or between a chip layer on the one hand and one of the outer or inner wall layers on the other.

Es ist gefunden worden, daß dann, wenn die Späne gestopft sind, wenn also das Volumen stark verringert ist, die Isolationswirkung gegen Wärmedurchgang zunimmt. Die Lufträume zwischen den Spänen sind geringer, so daß die Konvektionsströmungen unterbunden werden. Der Mehrverbrauch an Spänen fällt bei dem geringen Wert der Späne nicht ins Gewicht.It has been found that when the chips are stuffed, ie when the volume is greatly reduced, the insulation effect against heat transfer increases. The air spaces between the chips are smaller, so that the convection currents are prevented. The additional consumption of chips is negligible given the low value of the chips.

Von besonderem Vorteil ist bei der Erfindung insbesondere auch die Isolationswirkung gegen Schall. Dadurch, daß die Isolation aus mehreren Schichten aufgebaut ist, die eine unterschiedliche Steifigkeit und somit ein unterschiedliches Vibrationsverhalten besitzen, ergibt sich eine sehr gute Schalldämmung.The insulation effect against sound is particularly advantageous in the invention. The fact that the insulation is made up of several layers, which have a different stiffness and thus a different vibration behavior, results in very good sound insulation.

Von Vorteil ist weiter, daß beide Schichten, und zwar sowohl die erste wie die zweite Schicht aus umweltfreundlichem Material bestehen, so daß beispielsweise bei einem Abbruch bei der Entsorgung der Baustelle keine Probleme entstehen. Entsprechendes gilt auch für die Verwertung von Abfällen bei der Herstellung.It is also advantageous that both layers, namely both the first and the second layer, are made of environmentally friendly material, so that, for example, no problems arise when the construction site is disposed of. The same applies to the recycling of waste during production.

Die Anordnung mehrerer Schichten im Sinne der Erfindung ergibt auch Vorteile im Hinblick auf die Bekämpfung von Schädlingen jeglicher Art. Schädlinge, die beispielsweise die Späneschicht überwinden, werden von der verfestigten Schicht abgehalten.The arrangement of several layers within the meaning of the invention also results in advantages with regard to the control of pests of any kind. Pests which, for example, overcome the chip layer are prevented from the solidified layer.

Für die erste Schicht kommt vorzugsweise eine Mörtelschicht in Betracht. Dabei kann es sich um Gipsmörtel, Kalkmörtel, Zementmörtel oder dergleichen handeln. Auch Schichten, bei denen als Bindemittel Leim, Kasein, Latex oder Kunststoff verwendet werden, sind brauchbar.A mortar layer is preferably used for the first layer. This can be gypsum mortar, lime mortar, cement mortar or the like. Layers in which glue, casein, latex or plastic are used as binders can also be used.

Die erfindungsgemäße Isolation wird ohne besondere Maßnahmen dicht an den Distanzelementen anliegen, die die äußere Holzschicht und die innere Schicht miteinander verbinden. Im Gegensatz zu eingeschnittenen Plattenmaterial ergibt sich bei der Späneschicht keine Spaltbildung. Das Stopfen hat zudem den Vorteil, daß ein nachträgliches Zusammensacken vermieden wird.The insulation according to the invention will lie closely against the spacer elements which connect the outer wood layer and the inner layer to one another without special measures. In contrast to cut sheet material, there is no gap formation in the chip layer. The plug also has the advantage that subsequent collapse is avoided.

Auch in der ersten Schicht können teilweise Späne benützt werden, die als Füllmaterial dienen und von Bindemitteln zusammengehalten werden.Chips can also be used in the first layer, which serve as filler material and are held together by binders.

Die erste Schicht kann Bereiche aufweisen, die unverfestigt sind. Dies läßt sich dadurch erreichen, daß bei einer Mörtelschicht nur die außen liegenden Flächen angefeuchtet werden, so daß der Mörtel im Inneren nicht vollständig abbindet. Auf diese Weise wird erreicht, daß die erste Schicht mehrteilig aufgebaut ist, was sowohl die Schallisolierung als auch die Wärmeisolierung verbessert. Um ein Ausrieseln zu verhindern, empfiehlt es sich, hierbei Papier- oder Folienschichten vorzusehen.The first layer can have areas that are not consolidated. This can be achieved by moistening only the outer surfaces of a mortar layer, so that the mortar does not set completely on the inside. In this way it is achieved that the first layer is constructed in several parts, which improves both the sound insulation and the heat insulation. In order to prevent trickling out, it is advisable to provide layers of paper or foil.

Gute Ergebnisse werden dann erhalten, wenn die Isolierung aus einer mittleren, zweiten Schicht besteht, die beidseitig je von einer ersten Schicht abgedeckt ist. Auf diese Weise ist die Späneschicht nur sehr schwer entflammbar, zumal die ersten Schichten nur eine sehr geringe Luftdurchlässigkeit besitzen.Good results are obtained if the insulation consists of a middle, second layer, which is covered on both sides by a first layer. In this way, the chip layer is very difficult to ignite, especially since the first layers have very little air permeability.

Werden Hobelspäne verwendet, empfiehlt es sich, diese durch Stopfen auf etwa die Hälfte des Volumens zu verdichten.If shavings are used, it is advisable to compress them to about half the volume by plugging.

Zur Verbesserung der mechanischen Festigkeit kann es vorteilhaft sein, wenn in mindestens einer der Schichten Fäden oder Drähte eingelagert sind. Dies gilt insbesondere für die erste Schicht. Die eingelagerten Fäden oder Drähte stellen eine Armierung dar, die wenigstens über einen gewissen Zeitraum ein Zusammenbrechen der Schicht ausschließen, und zwar auch dann, wenn beispielsweise die Späneschicht in einem Brandfall zerstört ist. Es ist dabei nicht notwendig, daß nur unbrennbares Material verwendet wird, da das Material beispielsweise im Mörtel eingelagert ist. Es können daher auch Kunststoffäden, textile Materialien, Borsten, Holzdraht oder dergleichen Verwendung finden. Auch in der Späneschicht kann Drahtmaterial ein Gerüst bilden.To improve the mechanical strength, it can be advantageous if threads or wires are embedded in at least one of the layers. This applies in particular to the first layer. The embedded threads or wires represent a reinforcement that prevents the layer from collapsing at least over a certain period of time, even if, for example, the chip layer is destroyed in the event of a fire. It is not necessary that only non-combustible material is used, since the material is stored in the mortar, for example. Plastic threads, textile materials, bristles, wooden wire or the like can therefore also be used. Wire material can also form a framework in the chip layer.

Vorteilhaft ist es, wenn Distanzelemente vorgesehen sind, die die äußere Holzschicht und die innere Schicht verbinden und wenn diese Distanzelemente Nuten aufweisen, die den Rand der ersten Schicht aufnehmen. Da diese erste Schicht vorzugsweise plastisch eingebracht wird, entfällt eine besondere Einpassarbeit.It is advantageous if spacer elements are provided which connect the outer wood layer and the inner layer and if these spacer elements have grooves which accommodate the edge of the first layer. Since this first layer is preferably introduced plastically, special fitting work is not necessary.

Die Erfindung betrifft weiter ein Verfahren zur Herstellung einer Wand mit einer Isolierung. Die Erfindung schlägt dabei vor, daß die erste und die zweite Schicht im wesentlich gleichzeitig in den Zwischenraum eingebracht werden und daß die erste Schicht erst im Zwischenraum erhärtet.The invention further relates to a method for producing a wall with insulation. The invention proposes that the first and second layers are introduced into the intermediate space substantially simultaneously and that the first layer hardens only in the intermediate space.

Das gleichzeitige Einbringen der beiden Schichten in den Zwischenraum stellt sicher, daß von Anfang an eine gegenseitige Abstützung der beiden Schichten gegeben ist, so daß die relativ geringe mechanische Festigkeit insbesondere der ersten Schicht keine Nachteile ergibt. Das Einbringen in den Zwischenraum kann beispielsweise derart erfolgen, daß die Wandteile liegend gefertigt werden, wobei die innere oder äußere Schicht der Wand noch nicht aufgebracht ist. In die so gebildete Mulde werden gleichzeitig oder doch in geringem zeitlichem Abstand die verschiedenen Schichten eingebracht, also beispielsweise zunächst eine Mörtelschicht, dann die Späneschicht und dann wieder eine Mörtelschicht. Der Verdichtungsvorgang für die Späne kann dabei beim Aufbau der Wand oder auch an einem vorgeschalteten Arbeitsgang erfolgen. Anschließend wird die Mulde abgedeckt.The simultaneous introduction of the two layers into the intermediate space ensures that there is mutual support between the two layers from the start, so that the relatively low mechanical strength, in particular of the first layer, does not result in any disadvantages. The introduction into the intermediate space can take place, for example, in such a way that the wall parts are manufactured horizontally, the inner or outer layer of the wall having not yet been applied. The various layers are introduced into the trough formed in this way at the same time or at a short time interval, for example first a layer of mortar, then the layer of chips and then another layer of mortar. The compacting process for the chips can take place during the construction of the wall or in an upstream operation. The trough is then covered.

Das erfindungsgemäße Verfahren hat den Vorteil, daß eine Wand, die auf diese Weise gefertigt ist, sofort aufgerichtet werden kann. Es ist nicht notwendig, das Erhärten der ersten Schicht abzuwarten.The method according to the invention has the advantage that a wall which is produced in this way can be erected immediately can. It is not necessary to wait for the first coat to harden.

Vorteilhaft ist es, wenn die zweite Schicht befeuchtet in den Zwischenraum eingebracht wird. Befeuchtete Späne sind verhältnismäßig leicht verformbar und entwickeln nur verhältnismäßig geringe elastische Rückstellkräfte. Das Verdichten bzw. Stopfen wird hierdurch erleichtert. Wenn die Späne anschließend austrocknen, ergibt sich eine Spreizwirkung, die sich wiederum vorteilhaft auf die Abstützwirkung bezüglich der ersten Schicht äußert.It is advantageous if the second layer is introduced into the intermediate space in a moistened manner. Moisturized chips are relatively easy to deform and only develop relatively low elastic restoring forces. The compression or plugging is thereby facilitated. If the chips subsequently dry out, there is an expansion effect, which in turn has an advantageous effect on the support effect with respect to the first layer.

Die Feuchtigkeit der befeuchteten zweiten Schicht kann auch dazu benutzt werden, das Aushärten der ersten Schicht zu bewirken. Auf diese Weise ergibt sich, daß die der zweiten Schicht benachbarten Bereiche der ersten Schicht erhärten, daß aber weiter entfernte Bereiche nicht oder nur unwesentlich erhärten.The moisture of the moistened second layer can also be used to cause the first layer to cure. In this way, it follows that the regions of the first layer adjacent to the second layer harden, but that regions that are further away do not harden, or harden only insignificantly.

Bei einer Variante des erfindungsgemäßen Verfahrens ist vorgesehen, daß die erste und die zweite Schicht mittels einer Kletterschalung in den Zwischenraum eingebracht werden, wobei die Kletterschalung fortlaufend angehoben und gleichförmig aus getrennten Auslässen die Späne und ein das Bindemittel aufweisende Gemisch abgibt, wobei Stopfeinrichtungen insbesondere auf die Späne einwirken. Auf diese Weise läßt sich eine Wand stehend herstellen.In a variant of the method according to the invention, it is provided that the first and the second layer are introduced into the intermediate space by means of climbing formwork, the climbing formwork continuously being raised and delivering the chips and a mixture comprising the binder uniformly from separate outlets, with stuffing devices in particular on the Chips act. In this way, a wall can be made standing.

Aus den Darstellungen der Fig. 1 und 2 geht hervor, daß die Wand eine äußere Holzschicht 6 und eine innere Schicht 7 aufweist. Die äußere Holzschicht 6 kann aus Bohlen bestehen, die durch eine Nut- und Federanordnung 10, wie an sich bekannt, miteinander verbunden sind. Die innere Schicht 7 kann aus Profilbrettern aufgebaut sein. Für die innere Schicht können aber auch andere, beispielsweise plattenartige Bauelemente Verwendung finden.1 and 2 show that the wall has an outer wooden layer 6 and an inner layer 7. The outer wooden layer 6 can consist of planks which are connected to one another by a tongue and groove arrangement 10, as is known per se. The inner layer 7 can be constructed from profiled boards. Other, for example plate-like, components can also be used for the inner layer.

Der Holzrahmen 5, der die innere und äußere Schicht 6 und 7 miteinander verbindet, dient als Distanzelement.The wooden frame 5, which connects the inner and outer layers 6 and 7, serves as a spacer.

Zwischen den Schichten 6 und 7 ist die Isolierung angeordnet.The insulation is arranged between the layers 6 and 7.

Beim Ausführungsbeispiel nach der Fig. 1 besteht diese Isolierung aus insgesamt fünf Schichten. Dabei wechseln sich die Schichten 1 mit den Schichten 2 ab. Die Schicht 1 ist beispielsweise eine Mörtelschicht, während die Schicht 2 im wesentlichen aus gestopften Holzspänen besteht. Für die innere Schicht 1, die eine Mörtelschicht ist, ist im Distanzelement 5 eine Nut 8 vorgesehen, so daß insbesondere die Winddichtigkeit wesentlich verbessert wird. Derartige Nuten 8 können auch bei den anderen gezeigten Ausführungsbeispielen der Erfindung angewandt werden.In the embodiment according to FIG. 1, this insulation consists of a total of five layers. Layers 1 alternate with layers 2. Layer 1 is, for example, a layer of mortar, while layer 2 consists essentially of stuffed wood shavings. For the inner layer 1, which is a mortar layer, a groove 8 is provided in the spacer element 5, so that in particular the windproofness is significantly improved. Such grooves 8 can also be used in the other exemplary embodiments of the invention shown.

Die Schichten 2 aus gestopften Spänen und die Schichten 1 füllen den Zwischenraum zwischen den Schichten 6 und 7 völlig aus. Dadurch wird erreicht, daß sich die Schichten 1 und 2 gegenseitig jeweils stützen. Dies gilt sowohl zum Zeitpunkt des Einbringens dieser Schichten, wenn die Schichten 1 noch nicht erhärtet sind, als auch später in dem Zustand, in dem sich die Schichten 1 bereits verfestigt haben. Wenn beispielsweise im Laufe der Zeit in der Mörtelschicht 1 Risse auftreten, ist dies ohne weitere Bedeutung, da diese Schichten nicht zusammenfallen können, da sie von den Späneschichten gestützt werden.The layers 2 of stuffed chips and the layers 1 completely fill the space between the layers 6 and 7. It is thereby achieved that the layers 1 and 2 support each other. This applies both at the time these layers are introduced, if the layers 1 have not yet hardened, and later in the state in which the layers 1 have already solidified. If, for example, cracks appear in the mortar layer 1 over time, this is of no further importance since these layers cannot collapse because they are supported by the chip layers.

Beim Ausführungsbeispiel nach der Fig. 2 ist eine mittlere Späneschicht 2 von den Schichten 1 eingehüllt, die jeweils ein Bindemittel aufweisen. Die Schichten 1 besitzen dabei Bereiche 3, die unverfestigt sind, also beispielsweise sandförmig oder pulverförmig sind. Eine solche Anordnung wird erreicht, wenn beim Einbringen nur die Bereiche 13 der Schicht 1 befeuchtet werden, die an der Schicht 2 anliegen, beispielsweise dadurch, daß die zur Aushärtung notwendige Feuchtigkeit von der befeuchteten Schicht 2 aufgebracht wird. Wenn die Schicht 1 Bereiche besitzt, die nicht verfestigt sind, empfiehlt es sich, Papier- oder Folienzwischenlagen 12 zu verwenden, um ein Ausrieseln aus den Bereichen 3 der Schicht 1 zu verhindern. Die Verwendung derartiger sand- oder pulverförmiger Schichten verbessert den Schallschutz wesentlich.In the exemplary embodiment according to FIG. 2, a middle chip layer 2 is enveloped by the layers 1, which each have a binder. The layers 1 have areas 3 that are not consolidated, that is, for example, sand or powder. Such an arrangement is achieved when only the areas 13 of layer 1 which are in contact with layer 2 are moistened during the introduction, for example by the moisture required for curing being applied by the moistened layer 2. If layer 1 has areas that are not solidified, it is advisable to use paper or film intermediate layers 12 in order to prevent trickling out of areas 3 of layer 1. The The use of such sand or powder layers significantly improves sound insulation.

In der Fig. 2 ist angedeutet, daß sowohl in die Schichten 1 als auch in die Schichten 2 Fäden oder Drähte 4 eingefügt werden können, die als Armierung wirken.In Fig. 2 it is indicated that threads or wires 4 can be inserted into both layers 1 and 2, which act as reinforcement.

Die Fig. 3 zeigt die Herstellung der Wand gemäße der Erfindung in liegender Stellung. Die in der Fig. 3 mit strichpunktierten Linien angedeutete innere Schicht 7 wird dabei erst nachträglich nach Einbringen der Isolation aufgelegt. Die Wand besteht zunächst nur aus der äußeren Schicht 6 und den Distanzelementen 5. Die so gebildete Mulde wird in einem einzigen Arbeitsgang durch ein Einschüttgerät 14 gefüllt, das entsprechend den gewünschten Schichten mit beispielsweise drei Kanälen 15, 16 oder 17 ausgestaltet ist. Durch die Kanäle 15 und 17 wird der Mörtel oder eine geeignete Substanz anderer Zusammensetzung eingebracht und durch den Kanal 16 die Schicht 2 aus den gestopften Spänen. Die Zusammenpressung der Späne kann dabei im Augenblick des Einfüllens erfolgen, was durch die Pfeile 18 angedeutet ist. Die Rüttler 19 erleichtern das Einfließen der Massen insbesondere für die Schichten 1. Während des Einfüllvorganges bewegt sich entweder das Einschüttgerät 14 in Richtung des Pfeiles 20 oder die Wand wird in Richtung des Pfeiles 21 unter dem Einschüttgerät entlang gezogen.Fig. 3 shows the manufacture of the wall according to the invention in a lying position. The inner layer 7, indicated by dash-dotted lines in FIG. 3, is only subsequently placed after the insulation has been introduced. The wall initially consists only of the outer layer 6 and the spacer elements 5. The trough formed in this way is filled in a single operation by a pouring device 14, which is designed with three channels 15, 16 or 17, for example in accordance with the desired layers. The mortar or a suitable substance of different composition is introduced through the channels 15 and 17 and the layer 2 of the stuffed chips through the channel 16. The chips can be pressed together at the moment of filling, which is indicated by the arrows 18. The vibrators 19 facilitate the flow of the masses, in particular for the layers 1. During the filling process, either the pouring device 14 moves in the direction of arrow 20 or the wall is pulled along in the direction of arrow 21 under the pouring device.

Das Einfüllen der Isolation kann auch schichtenweise erfolgen, beispielsweise in der Art, daß zunächst die untere Schicht 1 eingefüllt wird und daß dann anschließend die Späne, insbesondere in befeuchtetem Zustand eingelegt werden und durch geeignete Mittel zusammengepreßt werden. Anschließend wird die obere Schicht 1 eingebracht und schließlich die innere Schicht 7. Es wurde gefunden, daß bei einer solchen Herstellungsweise und auch bei der vorstehend beschriebenen kontinuierlichen Fertigungsart gemäß Fig. 3 kein gegenseitiges Durchdringen der einzelnen Schichten in nennenswertem Umfang auftritt.The insulation can also be filled in layers, for example in such a way that first the lower layer 1 is filled in and then the chips are then inserted, in particular in a moistened state, and pressed together by suitable means. Then the upper layer 1 is introduced and finally the inner layer 7. It has been found that with such a production method and also with the continuous process described above 3 no mutual penetration of the individual layers occurs to a significant extent.

In der Fig. 4 ist eine Fertigung einer Wand gemäß der Erfindung gezeigt, unter Verwendung einer Kletterschalung. Die Wand besteht in diesem Fall aus der äußeren Holzschicht 6 und der inneren Schicht 7 sowie dem Distanzelement 5. Die Wand kann dabei aufrecht stehen, etwa in der Lage, wie sie später eingebaut wird. Die Wand kann aber auch auf die Seite gelegt sein. Im Inneren der aus den Teilen 5, 6 und 7 bestehenden Wand ist die schematisch angedeutete Kletterschalung untergebracht. Die Masse für die Bildung der Schichten 2 gleitet von oben nach unten zwischen die Schichten 6 und 7. Die Masse zur Bildung der Schichten 1 wird dagegen durch horizontal verlaufende Schnecken 22 zugefördert und treten aus diesen Schnecken nach unten aus. Oberhalb der Schnecken sind Schwenkklappen 23 gelagert, die eine Schwenkbewegung von etwa 180° ausführen. Der Antrieb der Schwenkklappen erfolgt durch ein Gestänge 24 an den Enden der Schwenkklappen und durch einen schematisch angedeuteten Motor 25, so daß die Zuströmung der Späne für die Schichten 2 nicht gestört wird. Die Schwenkklappen verdichten die Späne für die Schichten 2, und in einer gleichförmigen Bewegung der Kletterschalung 26 nach oben erfolgt die Befüllung des Raumes zwischen den Schichten 6 und 7.4 shows a production of a wall according to the invention, using climbing formwork. In this case, the wall consists of the outer wood layer 6 and the inner layer 7 as well as the spacer element 5. The wall can stand upright, approximately in the position in which it is installed later. The wall can also be placed on the side. Inside the wall consisting of parts 5, 6 and 7, the schematically indicated climbing formwork is housed. The mass for the formation of the layers 2 slides from top to bottom between the layers 6 and 7. The mass for the formation of the layers 1, on the other hand, is conveyed by horizontally running screws 22 and emerge from these screws downwards. Swivel flaps 23 are mounted above the screws, which execute a swivel movement of approximately 180 °. The swivel flaps are driven by a linkage 24 at the ends of the swivel flaps and by a schematically indicated motor 25, so that the inflow of chips for the layers 2 is not disturbed. The swivel flaps compress the chips for the layers 2, and the space between the layers 6 and 7 is filled in a uniform movement of the climbing formwork 26 upwards.

Bei der Variante nach den Fig. 5 und 6 werden die Massen zur Bildung der beiden seitlichen Schichten 1 parallel zu den Massen zur Bildung der Schicht 2 eingefüllt. Die Wände 27 der Kletterschalung trennen beim Einfüllvorgang die beiden Massen für die Schichten 1 und 2. Am unteren Ende der Kletterschalung sind Schwenkklappen 23 vorgesehen, die in diesem Fall Schwenkbewegungen um etwa einen rechten Winkel ausführen, um die Späne zur Bildung der Schicht 2 zu verdichten. Im unteren Bereich der Kletterschalung trennt die elastische Folie 28 die Massen zur Bildung der beiden Schichten.In the variant according to FIGS. 5 and 6, the masses for forming the two lateral layers 1 are filled in parallel to the masses for forming layer 2. The walls 27 of the climbing formwork separate the two masses for layers 1 and 2 during the filling process. Swing flaps 23 are provided at the lower end of the climbing formwork, which in this case perform swiveling movements by approximately a right angle in order to compact the chips to form layer 2 . In the lower area of the climbing formwork, the elastic film 28 separates the masses to form the two layers.

Weitere Preßklappen 29 drücken auch die plastischen Massen für die Schicht 1 nach unten.Further press flaps 29 also press the plastic masses for layer 1 downwards.

Die Fig. 6, die einen horizontalen Schnitt darstellt, zeigt, daß für die Kletterschalung 26 eine Rohrführung 30 vorgesehen ist, die in den Ecken des Raumes angeordnet ist, der von den Schichten 6 und 7 und den Distanzelementen 5 gebildet ist. Der Antriebsmotor 25 und die Gestänge 32 für die Schwenkklappen können beispielsweise auch zentral angeordnet sein.Fig. 6, which shows a horizontal section, shows that a pipe guide 30 is provided for the climbing formwork 26, which is arranged in the corners of the space formed by the layers 6 and 7 and the spacers 5. The drive motor 25 and the linkage 32 for the swivel flaps can also be arranged centrally, for example.

Für die Rohrführungen können auch Räume 31 freigehalten sein, die später zur Verlegung von Installationsleitungen benutzbar sind.Rooms 31 can also be kept free for the pipe guides, which can later be used for laying installation lines.
