Abstract

The cladding boards (4,5) are of wood, plaster or fibre board, etc. The zigzag structure (1) between them is formed by planks joined together, or a pressing of wood chips or fibre. The internal spaces formed are filled with mineral or vegetable fibre forming insulating material, cork, mineral or ceramic material in bulk, lightweight bulk-porous or aerated concrete, etc. (6,7). The planks can be joined together so as to resist thrust loads, being chamfered at 45 deg. along their lengthwise edges, so as to form isosceles right-angles triangles. The chamfers form flat surfaces (13), to which the boards are fixed.

Description

Diese Erfindung bezieht sich auf Wand-, Decken-, oder Dachelemente für Gebäude in Tafelbauart, die aus Holz oder formgepressten Holzwerkstoffen hergestellt werden, und auf die ein- oder beidseitig eine Beplankung aus Holz, Holzwerkstoffen, Gipskartonplatten, Zementfaserplatten o. dgl. befestigt ist, wobei deren Hohlräume mit schall- und wärmedämmenden Materialien ausgefüllt sind.This invention relates to wall, ceiling, or roof elements for buildings in panel construction, which are made of wood or molded wood-based materials, and on one or both sides a planking made of wood, wood-based materials, plasterboard, cement fiber boards or the like is attached , whose cavities are filled with sound and heat insulating materials.

Bekannte Wand-, Decken-, oder Dachelemente bestehen im wesentlichen aus einer mit Stegen aus Holz oder Holzwerkstoffen ausgefachten Holzrahmenkonstruktion mit beidseitig aufgebrachten Beplankungen, wobei die Stege einem stehenden rechteckigen Quader entsprechen, dessen Breitflächen mit der Beplankung einen rechten Winkel bilden. Die auf diese Weise gebildeten Hohlräume werden vorzugsweise mit leichten Mineralfaser-, Pflanzenfaser-Dämmstoffen, Kork o. dgl. ausgefüllt.Known wall, ceiling, or roof elements essentially consist of a wooden frame construction with webs made of wood or wooden materials with planks applied on both sides, the webs corresponding to a standing rectangular cuboid, the wide areas of which form a right angle with the planking. The cavities formed in this way are preferably filled with light mineral fiber, vegetable fiber insulation, cork or the like.

Der Nachteil derartiger Elemente besteht in dem Umstand, daß mit den leichten Dämm-Materialien zwar gute Wärme- und Luftschalldämmwerte erzielt werden, aber gute Körperschalldämmwerte nur mit einem erhöhten konstruktiven Aufwand, in Form von getrennten Schalen, zusätzlicher Beschwerung der Schalen o. dgl. zu erzielen sind. Dieses bedeuted insbesondere unter Berücksichtigung des statischen Trageverhaltens derartiger Elemente einen hohen Montageaufwand, der zumeist bauseitig zu erfolgen hat.The disadvantage of such elements is the fact that with the light insulation materials good thermal and airborne sound insulation values can be achieved, but good structure-borne noise insulation values only with increased design effort, in the form of separate shells, additional weighting of the shells or the like are achieved. This means, in particular taking into account the static wearing behavior of such elements, a high level of assembly effort, which usually has to be carried out on site.

Zudem finden bekannte Elemente vornehmlich im Ein- und Zweigeschoßbau Verwendung, weil ihre Tragfähigkeit durch die bauphysikalisch sinnvolle Anordnung und Dimensionierung des Steg- und Dämmaterials begrenzt wird. Andernfalls führt dieses im Mehrgeschoßbau zu einem erhöhten konstruktiven Aufwand in Form von gesonderten Rahmen- und Stützkonstruktionen, Tramlagen, Dachsparren o.dgl., an welche bekannte Tafelelemente entsprechend angeschlossen werden, um eine zu hohe Anzahl von Schall- und Wärmebrücken in den Wand-, Decken-, oder Dachelementen selbst zu vermeiden.In addition, known elements are mainly used in single and two-storey buildings because their load-bearing capacity is limited by the arrangement and dimensioning of the web and insulation material that makes sense in terms of building physics. Otherwise, in multi-storey construction, this leads to an increased design effort in the form of separate frame and support structures, tram locations, rafters or the like, to which known panel elements are connected accordingly in order to avoid an excessive number of sound and heat bridges in the wall, Avoid ceiling or roof elements themselves.

Ziel dieser Erfindung ist, die Nachteile der eingangs beschriebenen Art zu vermeiden und vielseitig verwendbare, leichte Wand-, Decken-, oder Dachelemente für Gebäude in Tafelbauart mit guten schall- und wärmetechnische Eigenschaften zu schaffen, die in einem hohen Fertigungsgrad industriell hergestellt werden können und bauseitig nur mehr in geeigneter Weise verbunden werden müssen. Weiters ist das Ziel dieser Erfindung hochtragfähige Wand- und Deckenelemente zur Verfügung zu stellen, die ohne wesentliche zusätzliche Rahmen- oder Stützkonstruktionen eine mehrgeschoßige Bauweise in Tafelbauart ermöglichen, wobei die Dicke der Bauteile nicht größer als bei bekannten Produkten ist.The aim of this invention is to avoid the disadvantages of the type described in the introduction and to provide versatile, light wall, ceiling or roof elements for buildings in panel construction with good sound and thermal properties, which can be industrially produced in a high degree of manufacture and only need to be connected in a suitable manner on site. Furthermore, the aim of this invention is to provide high-load-bearing wall and ceiling elements which, without substantial additional frame or support structures, enable a multi-storey panel-type construction, the thickness of the components being no greater than in known products.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß zunächst eine Faltwerk-Konstruktion (bzw. ein Faltwerk) aus Holz oder formgepressten Holzwerkstoffen gefertigt wird, die im Endprodukt hauptsächlich die statisch tragende Funktion übernimmt. Bei schubsteif verbundenen Holzbrettern entspricht die Faltwerk-Konstruktion im Querschnitt den Konturen rechtwinkeliger, gleichschenkeliger Dreiecke. Bei Verwendung formgepresster Holzwerkstoffe sind, neben der zuvor beschriebenen Form, auch trapezförmige Konturen, tonnenschalenförmige und sinuswellenförmige Konturen des Faltwerkes möglich. Alle Faltwerke bzw. Faltwerk-Konstruktionen sind mit ebenen Gratflächen versehen, auf denen die Anbindung der Beplankung erfolgen kann, wobei die entsprechende Beplankung für Fertig-Oberflächen vorbereitet oder anforderungsgemäß mit weiteren Schalen ausgestattet sein kann.According to the invention, this object is achieved in that a folding structure (or a folding structure) is first made of wood or molded wood-based materials, which in the end product mainly takes on the structural function. In the case of rigid wooden boards, the cross-sectional construction corresponds to the contours of right-angled, isosceles triangles. When using molded wood-based materials, in addition to the shape described above, trapezoidal contours, barrel-shaped and sinusoidal contours of the folding mechanism are also possible. All folding units or folding unit constructions are provided with flat ridge surfaces on which the planking can be connected, whereby the corresponding planking can be prepared for finished surfaces or can be equipped with additional shells as required.

Die sich durch das Faltwerk bzw. die Faltwerk-Konstruktion ergebenden Hohlräume können wie folgt ausgefüllt sein.The cavities resulting from the folding mechanism or the folding mechanism construction can be filled as follows.

Außenwand-Elemente können beidseitig beplankt und in der Weise mit Hohlraumfüllungen versehen sein, daß leichte wärmedämmende Materialien die Mineralfaser-, Pflanzenfaserstoffe, Papierflocken, Kork, expandierte Stoffe o. dgl., mit dem in der Faltwerk-Gratflächenebene gemessenen größten Flächenanteil außen liegen, schwere speicherwirksame Materialien mit gutem Wärmedämmvermögen, wie Schaumbetone oder betongebundener Blähton o. dgl., oder auch Beschüttungen mit Sand, Kies, Bimskiese, Schlacken, Schaumlava, Blähton o. dgl. raumseitig den größten Flächenanteil einnehmen.Outer wall elements can be planked on both sides and provided with cavity fillings in such a way that light, heat-insulating materials such as mineral fibers, vegetable fibers, paper flakes, cork, expanded materials or the like, with the largest proportion of the area measured in the folded burr surface area, are heavy Storage-effective materials with good thermal insulation properties, such as foam concrete or concrete-bound expanded clay or the like, or also fillings with sand, gravel, pumice, slag, foam lava, expanded clay or the like occupy the largest proportion of space on the room side.

Bei Wohnungstrennwänden und Innenwänden kann die Anbringung entsprechender Beplankung sowie ggf. zusätzlicher Schalen und die Anordnung der Befüllung nach örtlichen Gegebenheiten erfolgen.In the case of apartment partitions and interior walls, the appropriate planking and, if necessary, additional shells and the arrangement of the filling can be done according to local conditions.

In einem erfindungsgemäßen Deckenelement mit beidseitiger Beplankung, können sämtliche Hohlräume mit leichten wärmedämmenden Materialien ausgefüllt sein und - in Verbindung mit einer geeigneten. Außenschale - zu einem Warmdach zusammengesetzt werden. Weiters können derartige erfindungsgemäß vorgeschlagene Elemente allgemein als gegen die Außenluft abgrenzende Bauteile eingesetzt werden, wenn dieselben mit einer entsprechenden Beplankung und Außenschale gefertigt sind.In a ceiling element according to the invention with planking on both sides, all cavities can be filled with light, heat-insulating materials and - in conjunction with a suitable one. Outer shell - to be assembled into a warm roof. Furthermore, such elements proposed according to the invention can generally be used as components delimiting against the outside air if they are manufactured with a corresponding planking and outer shell.

Unter einem Kaltdach als oberste Geschoßdecke befindliche Deckenelemente dieser Erfindung können nur raumseitig beplankt sein, wobei die dadurch gebildeten Hohlräume sowie die dachseitigen Leerräume des Faltwerkes bzw. der Faltwerk-Konstruktion mit Wärmedämmstoffen ausgefüllt sind.Ceiling elements of this invention located under a cold roof as the top floor ceiling can only be planked on the room side, the cavities formed thereby and the roof-side empty spaces of the folded structure or the folded structure being filled with thermal insulation materials.

Innenliegende Deckenelemente können erfindungsgemäß auf zwei unterschiedliche Arten ausgeführt werden.

  • 1.) können innenliegende Deckenelemente aus einer beidseitig beplankten Faltwerk-Konstruktion (bzw. Faltwerk) bestehen, deren Hohlräume in der Weise befüllt sind, daß in den, über der raumseitigen Beplankung befindlichen Hohlräumen leichte Wärmedämmstoffe eingebaut werden, während in den Hohlräumen unter der oberen Beplankung eine Beschüttung mit oben genannten Stoffen oder eine Befüllung mit Schaumbetonen etc. vorgesehen sein kann. Dergestalte Deckenelemente können oberseitig einen bekannten Fußbodenaufbau erhalten und unterseitig tapezier- bzw. streichfertig oder mit Holz-Panelen o. dgl. gestaltet sein. Diese vorgeschlagene Ausführungsform stellt sehr tragfähige Deckenelemente mit großen freien Spannlängen bereit.
  • 2.) können innenliegende Deckenelemente aus einer nur unterseitg beplankten Faltwerk-Konstruktion (bzw. Faltwerk) bestehen, deren mit der Beplankung gebildeten Hohlräume wie unter Punkt 1. ausgefüllt sind, und die oberseitig mit einer Beschüttung aus Sand, Kies, etc. bauseitig angefüllt werden. Der Fußbodenaufbau erfolgt in bekannter Weise auf dem Beschüttungsmaterial, entweder mit darauf in geeigneten Abständen aufliegenden Polsterhölzern mit dazwischenliegenden Dämmstoffen und darüberliegenden Trockenestrichen, Spanplatten und Parketten, oder auf einer darauf angeordneten Trittschalldämmung mit schwimmend verlegten Fußböden. Bei dieser vorgeschlagenen Ausführungsform können für Körperschall ungünstige Schallübertragungswege zu Flankenbauteilen vermieden werden.
Interior ceiling elements can be designed according to the invention in two different ways.
  • 1.) Internal ceiling elements can consist of a pleated structure (or pleated structure) planked on both sides, the cavities of which are filled in such a way that light thermal insulation materials are installed in the cavities above the planking on the room side, while in the cavities below the upper one Planking, a filling with the above-mentioned substances or a filling with foam concrete etc. can be provided. Such ceiling elements can have a known floor structure on the top side and can be papered or coated on the underside or can be designed with wood panels or the like. This proposed embodiment provides very stable ceiling elements with large free span lengths.
  • 2.) Internal ceiling elements can consist of a pleated structure (or pleated structure) that is only planked on the underside, the cavities formed with the planking are filled as in point 1, and the top side is filled with a fill of sand, gravel, etc. on site become. The floor is built up in a known manner on the fill material, either with upholstery wood lying on it at suitable intervals with insulation materials in between and overlying dry screeds, chipboard and parquets, or on impact sound insulation arranged thereon with floating floors. In this proposed embodiment, sound transmission paths to flank components that are unfavorable for structure-borne noise can be avoided.

Ein Vorteil dieser erfindungsgemäß vorgeschlagenen Wand-, Decken-, oder Dachelemente liegt darin, daß beiderseits des Faltwerkes bzw. der Faltwerk-Konstruktion Leerräume enstehen, die eine Befüllung in der Art zulassen, daß durch eine geeignete Kombination unterschiedlicher Dämmstoffe in Verbindung mit dem Faltwerkmaterial eine günstige Verbundwirkung hinsichtlich der schall- und wärmetechnischen Eigenschaften ermöglicht wird. Es können Materialien unterschiedlicher Dichte und Beschaffenheit, wie lose Fasermaterialien, Filze, Festkörper, Beschüttungen etc. miteinander kombiniert werden, sodaß sowohl Luftschall- und Körperschalldämmung als auch erforderliche K-Werte und wärmespeicherwirksame Massen ohne konstruktiven Mehraufwand erreicht werden können.An advantage of these wall, ceiling, or roof elements proposed according to the invention is that empty spaces are created on both sides of the folding mechanism or the folding mechanism construction, which allow filling in such a way that a suitable combination of different insulating materials in conjunction with the folding material favorable composite effect in terms of sound and thermal properties is made possible. Materials of different densities and properties, such as loose fiber materials, felts, solids, fillings, etc. can be combined with one another, so that both airborne and structure-borne noise insulation as well as the required K-values and heat-storing masses can be achieved without additional design effort.

Weiters wird bei dieser Erfindung durch das Faltwerk bzw. die Faltwerk-Konstruktion eine Schallverzweigung, ein längerer Übertragungsweg zwischen den Beplankungen, sowie geringere direkte Schallübertragungsflächen zwischen den Stegen und der Beplankung erreicht, als bei bekannten Wand- und Deckenelementen mit gleicher Tragfähigkeit.Furthermore, in this invention, the folding mechanism or the folding mechanism construction achieves sound branching, a longer transmission path between the planking, and less direct sound transmission surfaces between the webs and the planking than known wall and ceiling elements with the same load-bearing capacity.

Ebenso ist ein Vorteil dieser Erfindung, daß mit einem hohen maschinellen Fertigungsgrad und geringem bauseitigem Montageaufwand Bauteile für unterschiedliche Anforderungen mit gleicher Grundstruktur hergestellt werden können. Insbesondere, wenn ein Faltwerk aus formgepressten Holzwerkstoffen wie bekanntem Oriented Strand Board oder Funierstreifenholz gefertigt wird und nurmehr mit entsprechender Beplankung und Hohlraumfüllung versehen wird, werden hochtragfähige Bauelemente geschaffen, die in zukunft einen mehrgeschößigen Wohnbau zu weit geringeren Kosten ermöglichen können, als dies durch bisher bekannte Produkte möglich ist.It is also an advantage of this invention that components can be manufactured for different requirements with the same basic structure with a high degree of mechanical production and low on-site assembly costs. In particular, if a folding mechanism is made from molded wood-based materials such as the well-known Oriented Strand Board or veneer strip wood and is only provided with the appropriate planking and cavity filling, high-load-bearing components will be created, which in the future can enable multi-story residential construction at far lower costs than previously known Products is possible.

Fig. 3 zeigt beispielsweise ein Wand-, Decken-, oder Dachelement in dem das Faltwerk 2 in der Grundstruktur entsprechend den Konturen eines rechtwirkeligen, gleichschenkeligen Dreiecks zusammengesetzt ist, wobei die Kehlen entsprechend den technischen Gegebenheiten des Formenbaus ebenso wie die Gratflächenkanten gerundet sind.Fig. 3 shows, for example, a wall, ceiling or roof element in which the folding structure 2 is composed in the basic structure according to the contours of a right-angled, isosceles triangle, the throats being rounded according to the technical conditions of mold construction as well as the edges of the ridges.

Das Faltwerk 2 wird in einem Teil entsprechenden Ausmaßes aus formgepressten Holzwerkstoffen wie z. B. OSB, Funierstreifenholz o. dgl. mit ebenen Gratflächen gefertigt, auf welche beidseitig eine Beplankung 4,5 geklebt ist. Sämtliche auf diese Weise gebildeten Hohlräume werden mit Wärmedämmstoffen 6 ausgefüllt. Dieses Element kann, mit einer innenseitigen Dampfsperre und entsprechender Außenschale versehen, vorteilhaft zu einem Warmdach zusammengesetzt sein, oder als oberste Geschoßdecke unter einem Kaltdach eingesetzt werden. Weiters kann dieses Element als wärmedämmende, tragende Wand eingesetz werden, wenn keine hohen schalltechnischen Anforderungen gestellt werden.The folding mechanism 2 is made to a certain extent from molded wood-based materials such as B. OSB, Funierstreifenholz o. The like. Made with flat ridges, on which a planking 4.5 is glued on both sides. All cavities formed in this way are filled with thermal insulation materials 6. This element, provided with an internal vapor barrier and a corresponding outer shell, can advantageously be assembled to form a warm roof, or can be used as the top floor ceiling under a cold roof. Furthermore, this element can be used as a heat-insulating, load-bearing wall if there are no high acoustic requirements.

Fig. 4 zeigt beispielsweise ein nach außen abgrenzendes Wandelement auf deren Faltwerk-Konstruktion 1 außenseitig eine OSB-Platte (z.B. V100-Verleimung) 5 und raumseitig eine OSB-Platte (z.B. V20-Verleimung) 4 aufgeklebt ist. Die Außenschale besteht aus einem aufgenagelten Nut- und Federprofil 12 in Fichte, die Innenschale aus einer Dampfbremse 10 und aufgenagelter Gipskartonplatte 11, die für eine Fertig-Oberfläche vorbereitet ist. In die außenliegenden Hohlräume werden Keile aus Mineralwoll-Filz 6 passend eingelegt, innenliegend werden entsprechend geformte Keile aus schaumbetongebundenen Blähtonkörnern 7, vorzugsweise mit einer Dichte > 900 kg/m³, mit weichelastischen Klebstoffen in den Hohlräumen befestigt. Die auf diese Weise mit leichten Wärmedämmstoffen 6 kombinierten schweren Schaumbetonkörper 7 mit günstigem Wärmedämmwert (λR = 0,22 W/mK), bewirken, neben guten K-Werten (k< 0,40 W/m²K) sowie großer speicherwirksamer Masse, die sehr günstigen schalldämmenden Eigenschaften dieses Wandelementes. Durch die Faltwerk-Konstruktion 1 in Verbindung mit der beidseitigen Beplankung 4, 5 ensteht ein sehr tragfähiges System, wobei das Gesamt-Gewicht dieses beispielsweisen Wandelementes weniger als 140 kg/m² und die Dicke 23,5 cm beträgt.4 shows, for example, an outwardly delimiting wall element on the folding structure 1 of which an OSB board (for example V100 gluing) 5 is glued on the outside and an OSB board (for example V20 gluing) 4 on the room side. The outer shell consists of a nailed tongue and groove profile 12 in spruce, the inner shell of a vapor barrier 10 and nailed plasterboard 11, which is prepared for a finished surface. Wedges of mineral wool felt 6 are inserted appropriately into the external cavities, and correspondingly shaped wedges made of expanded concrete granules 7 bound with foam concrete, preferably with a density> 900 kg / m³, are fastened in the cavities with soft-elastic adhesives. The heavy foam concrete body 7 combined with light thermal insulation materials 6 with a favorable thermal insulation value (λ R = 0.22 W / mK), in addition to good K values (k <0.40 W / m²K) and large storage-effective mass, result in very favorable sound-insulating properties of this wall element. The folding structure 1 in conjunction with the planking 4, 5 on both sides creates a very stable system, the total weight of this example wall element being less than 140 kg / m² and the thickness being 23.5 cm.

Weitere zweckgemäße Ausführungsformen sind den Unteransprüchen zu entnehmen.Further expedient embodiments can be found in the subclaims.
