Description

Wand- oder DachelementWall or roof element
Die Erfindung betrifft eine Verbindungsvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a connecting device according to the preamble of claim 1.
Aus der DE-A1-199 13 589 ist eine selbsttragende OSB-Bauplatte in Sandwichbauweise mit beidseitigen OSB-Deckplatten und einer zwischen diesen angeordneten Dämmschicht aus Holzspänen oder -abfall bekannt (OSB = oriented Strand board).DE-A1-199 13 589 discloses a self-supporting OSB building board in sandwich construction with OSB cover plates on both sides and an insulating layer of wood chips or waste arranged between them (OSB = oriented beach board).
Aus der DE-C2-32 08 839 ist eine Bauplatte in Sandwichbauweise bekannt, das mit Stahlblech-Deckplatten, mit einer Dämmschicht aus Schaumpolystyrol und mit Zwischenschichten aus Holzspanplatten zwischen den Deckplatten und der Dämmschicht versehen sein kann.From DE-C2-32 08 839 a building board in sandwich construction is known which can be provided with sheet steel cover plates, with an insulating layer made of foam polystyrene and with intermediate layers of chipboard between the cover plates and the insulating layer.
Durch die DE-A1 -19608483 ist eine vorgefertigte Leichtbauwand bekannt, die aus mehreren Isolierplatten besteht, die jeweils aus einer beidseitig beschichteten Kunststoffschaumschicht gebildet sind. Die Deckschichten bestehen aus mineralischFrom DE-A1 -19608483 a prefabricated lightweight wall is known, which consists of several insulating plates, each of which is formed from a plastic foam layer coated on both sides. The cover layers consist of mineral
BESTATIGUNGSKOPIE gebundener Holzwolle, während die Kunststoffschaumschicht aus Styropor gefertigt sein kann. An den Stirnseiten jeder Isolierplatte sind in der Kunststoffschaumschicht Nuten vorgesehen, in die eine Stützleiste eingeschoben oder eingeklebt ist.BESTATIGUNGSKOPIE bound wood wool, while the plastic foam layer can be made of styrofoam. On the end faces of each insulating plate, grooves are provided in the plastic foam layer, into which a support strip is inserted or glued.
Schließlich ist aus der DE-A1 -4207285 eine Verbundplatte bekannt, die aus einer Hartschaumschicht und zwei beidseitig mit dieser verklebten Deckschicht besteht. In der Hartschaumschicht sind zur Erhöhung der Biegefestigkeit der Verbundplatte Vertiefungen vorgesehen. Es werden Verbundplatten mit eingeschlossenen Holzleisten erwähnt. Das Material der Hartschaumschicht und der Deckschichten wird nicht erläutert.Finally, a composite panel is known from DE-A1 -4207285, which consists of a hard foam layer and two cover layers bonded to this on both sides. Wells are provided in the rigid foam layer to increase the flexural strength of the composite panel. Composite panels with enclosed wooden strips are mentioned. The material of the rigid foam layer and the cover layers is not explained.
Alle diese bekannten Bauplatten werden oft im Verbund miteinander als Wände oder Dächer verwendet, wobei der Verbund beispielsweise durch Verkleben der stumpf aufeinander oder nebeneinander gelegten Bauplatten, durch die Fugen überdeckende Klebestreifen oder durch Verklammern der Bauplatten erfolgt. Die Fugen zwischen den Bauplatten lassen sich durch die bekannten Mittel jedoch einerseits nicht dauerhaft abdichten, und andererseits wird keine genügende Stabilität der aus den Bauplatten zusammengefügten Wand oder des Dachs bei großen Bauplattenlängen (6 - 12 m) erreicht.All of these known building boards are often used in conjunction with one another as walls or roofs, the joining being carried out, for example, by gluing the building boards butted or juxtaposed, by adhesive strips covering the joints, or by clamping the building boards together. The joints between the building boards cannot be permanently sealed on the one hand by the known means, and on the other hand no sufficient stability of the wall or roof assembled from the building boards is achieved with large building board lengths (6-12 m).
Die Aufgabe der Erfindung besteht daher darin, eine Verbindungsvorrichtung gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, mit der einerseits die Fugendichtigkeit verbessert und andererseits die Stabilität der aus Bauplatten zusammengesetzten Wände oder Dächer erhöht werden kann.The object of the invention is therefore to provide a connecting device according to the preamble of claim 1, with which on the one hand the joint tightness is improved and on the other hand the stability of the walls or roofs composed of building boards can be increased.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Durch die Ausbildung der Deckplatten aus Sperrholzplatten wird eine Verformung der Bauplatte verhindert. Die Herstellung der Dämmschicht aus Polystyrol-Hartschaum verleiht der Bauplatte eine ausgezeichnete Stabilität und Wärme- und Geräuschdämmung. Zur Stabilität trägt vor allem aber der Holzwerkstoff-Körper bei, der sich gut mit den Sperrholzplatten verkleben lässt, wobei die Fugen luft- und wasserdicht abgedichtet werden.This object is achieved with the features of claim 1. Deformation of the building board is prevented by forming the cover plates from plywood plates. The production of the insulating layer from polystyrene hard foam gives the building board excellent stability and heat and noise insulation. Above all, the wood material body contributes to stability, which can be easily glued to the plywood panels, whereby the joints are sealed airtight and watertight.
Gemäß einer einfachen, weiteren Ausbildung der Erfindung ist der Körper durch mindestens eine blattförmige Leiste gebildet.According to a simple, further embodiment of the invention, the body is formed by at least one sheet-like bar.
Gemäß einer einfachen, weiteren Ausbildung der Erfindung ist der Körper eine Vollholzleiste mit der Dicke der Dämmschicht und mit beiden Deckplatten jeder Bauplatte verklebbar.According to a simple, further embodiment of the invention, the body is a solid wood strip with the thickness of the insulation layer and can be glued to both cover plates of each building board.
Gemäß einer alternativen, einfachen, weiteren Ausbildung der Erfindung ist der Körper eine Vollholzleiste mit einer geringeren Dicke als die Dämmschicht und mit den einen homologen Deckplatten zweier Bauplatten verklebbar.According to an alternative, simple, further embodiment of the invention, the body is a solid wood strip with a smaller thickness than the insulation layer and can be glued to the one homologous cover plate of two building boards.
Gemäß einer weiteren Ausbildung der Erfindung ist der Körper eine im Querschnitt doppel-T-förmige Leiste aus einem Steg und zwei Schenkeln. Diese T-Leiste ist leichter als die Vollholzleiste, und ferner wird weniger Holzmaterial benötigt.According to a further embodiment of the invention, the body is a cross-sectionally double-T-shaped bar consisting of a web and two legs. This T-bar is lighter than the solid wood bar and less wood material is required.
Gemäß weiteren Ausbildungen der Erfindung entspricht die Gesamtbreite der Leiste der Dicke der Dämmschicht, oder die Gesamtbreite der Leiste ist geringer als die Dicke der Dämmschicht. Dabei können die Schenkel der Leiste auf den Außenseiten der Deckplatten oder der Schenkel der Leiste auf der Außenseite der einen homologen Deckplatten und der andere Schenkel auf der Innenseite der anderen homologen Deckplatten angeordnet sein. Eine weitere Ausbildung der Erfindung sieht vor, dass der Körper eine im Querschnitt U-förmige Leiste mit einer Basis und zwei mit den Innenseiten der Deckplatten verklebbaren Schenkeln ist, dass die Basis der Dicke der Deckplatten entsprechende Überstände über die Schenkel aufweist und dass die Basis mit einer Deckplatte der zweiten Bauplatte verklebbar ist. Dabei kann die Leiste auch als Kantenabschlusselement eingesetzt sein. Diese U-Leiste eignet sich insbesondere zur Verbindung von Bauplatten, die rechtwinklig zueinander stehen.According to further developments of the invention, the total width of the strip corresponds to the thickness of the insulation layer, or the overall width of the strip is less than the thickness of the insulation layer. The legs of the bar can be arranged on the outside of the cover plates or the legs of the bar on the outside of one of the homologous cover plates and the other leg on the inside of the other homologous cover plates. A further embodiment of the invention provides that the body is a cross-sectionally U-shaped strip with a base and two legs that can be glued to the inner sides of the cover plates, that the base has projections corresponding to the thickness of the cover plates, and that the base with a cover plate of the second building board can be glued. The bar can also be used as an edge finishing element. This U-bar is particularly suitable for connecting building boards that are perpendicular to each other.
Die miteinander verklebten Deckplatten und Körper können gemäß einer weiteren Ausbildung der Erfindung zum besseren Halt zusätzlich mittels Nägel oder Schrauben verbindbar sein.According to a further embodiment of the invention, the cover plates and body glued together can additionally be connected by means of nails or screws for better hold.
Die Erfindung kann auch beim Aufbau von ganzen, auch mehrstöckigen Häusern mit Vorteil verwendet werden, weil gesonderte Stützgerüste für Zimmer-, Decken- und Dachwände nicht erforderlich sind.The invention can also be used to advantage in the construction of entire, even multi-storey houses, because separate support structures for room, ceiling and roof walls are not required.

In den Figuren sind Beispiele für Verbindungsvorrichtungen gezeigt, die zum fugendichten Verbinden von Bauplatten dienen, die in Sandwichbauweise jeweils zwei Holzwerkstoff-Deckplatten und eine von diesen eingeschlossene Kunststoffschaum- Dämmschicht aufweisen.In the figures, examples of connecting devices are shown, which are used for the joint-tight connection of building boards, the two in sandwich construction Have wood-based cover plates and a plastic foam insulation layer enclosed by them.
In Fig. 1 sind zwei solche Bauplatten 1 und 2 teilweise gezeigt, die als Deckplatten jeweils zwei Sperrholzplatten (oder OSB-Platten) 3, 4 bzw. 5, 6 und eine dazwischen liegende Dämmschicht 7 bzw. 8 aus Polystyrol-Hartschaum aufweisen. Die Sperrholzplatten sind mit der Dämmschicht fabrikseitig verklebt. Eine Verbindungsvorrichtung 9 verbindet die beiden Bauplatten 1 , 2 bauseits.In Fig. 1 two such building panels 1 and 2 are partially shown, each having two plywood panels (or OSB panels) 3, 4 and 5, 6 and an intermediate insulation layer 7 and 8 made of rigid polystyrene foam as cover plates. The plywood panels are glued to the insulation layer at the factory. A connecting device 9 connects the two building boards 1, 2 on site.
Die Verbindungsvorrichtung 9 besteht aus Fugen, wie den Fugen 10, 11 , die in jeder Bauplatte zwischen den Sperrholzplatten und der Dämmschicht angeordnet sind, und zwei blattförmigen Leisten 12, 13 aus Holzwerkstoff, vorzugsweise Sperrholz. Die Leisten 12, 13 können werksseitig bereits in die Bauplatte 1 eingesetzt und mit den Sperrholzplatten 3, 4 verklebt sein. Sie können aber auch erst auf der Baustelle eingesetzt werden. Um die Bauplatten 1 , 2 miteinander zu verbinden, werden die in der Bauplatte 1 eingefügten Leisten 12, 13 in die Fugen 10, 11 eingefügt und mit den Sperrholzplatten 5, 6 mittels Klebmittelaufträgen 14, 15 verklebt. Die Sperrholzplatten 3-6 in Verbindung mit den Leisten 12, 13 verleihen den beiden verbundenen Bauplatten 1 , 2 eine hohe Stabilität.The connecting device 9 consists of joints, such as the joints 10, 11, which are arranged in each building board between the plywood panels and the insulating layer, and two sheet-shaped strips 12, 13 made of wood-based material, preferably plywood.

The plywood boards 3-6 in connection with the strips 12, 13 give the two connected building boards 1, 2 a high stability.
Zusätzlich kann die Verbindungsvorrichtung 9 einen expandierenden Schaumauftrag 16 zwischen den Dämmschichten 7, 8, der diese miteinander verklebt, und eine Ver- nagelung, wie der Nagel 17, zwischen jeder Sperrholzplatte 3-6 und den Leisten 12, 13 aufweisen. Dadurch wird die Festigkeit der Verbindung der beiden Bauplatten 1 , 2 erhöht.In addition, the connecting device 9 can have an expanding foam application 16 between the insulating layers 7, 8, which glues them together, and a nailing, such as the nail 17, between each plywood sheet 3-6 and the strips 12, 13. This increases the strength of the connection of the two building boards 1, 2.
In Fig. 2 sind zwei Bauplatten 18, 19 teilweise dargestellt, die jeweils wieder wie in Fig. 1 zwei Sperrholzplatten 3, 4 bzw. 5, 6 und eine dazwischen liegende Dämm- schicht 7 bzw. 8 aus Polystyrol-Hartschaum aufweisen. Nuten 20-23 sind am Ende jeder Bauplatte 18, 19 zwischen den Sperrholzplatten und den Dämmschichten vorgesehen. Außer diesen Nuten umfasst die Verbindungsvorrichtung 24 eine im Querschnitt doppel-T-förmige Leiste 25 aus einem Steg 26 und zwei Schenkeln 27,In Fig. 2 two building boards 18, 19 are partially shown, each again as in Fig. 1, two plywood boards 3, 4 and 5, 6 and an intermediate insulation have layer 7 or 8 of rigid polystyrene foam. Grooves 20-23 are provided at the end of each building board 18, 19 between the plywood boards and the insulation layers. In addition to these grooves, the connecting device 24 comprises a bar 25 with a double T-shaped cross section, consisting of a web 26 and two legs 27,

29, 30, auf, mittels der die Schenkel 27, 28 nach ihrem Einfügen in die Nuten 20-23 mit den Sperrholzplatten 3-6 verklebt werden. Ferner kann die Verbindungsvorrichtung 24 zwei Lagen 31 , 32 aus Mineralwolle mit der Höhe des Stegs 26 aufweisen, die jeweils zwischen der Dämmschicht 7 bzw. 8 und dem Steg 26 eingefügt werden. Weiterhin kann wie in Fig. 1 auch eine Vernagelung vorgesehen werden. Die Stabilität des Bauplattenverbunds wird bei der vorstehend beschriebenen Ausführung erhöht.29, 30, by means of which the legs 27, 28 are glued to the plywood boards 3-6 after they have been inserted into the grooves 20-23. Furthermore, the connecting device 24 can have two layers 31, 32 of mineral wool with the height of the web 26, which are inserted in each case between the insulation layer 7 or 8 and the web 26. Furthermore, as in FIG. 1, nailing can also be provided. The stability of the building board composite is increased in the embodiment described above.
In den Figuren 4-6 und 8 sind weitere Beispiele für die Anordnung einer doppel-T- förmigen Leiste dargestellt. Diese Beispiele haben für die vorgesehenen Anwendungsvorfälle Vorteile. In Fig. 4 entspricht die Gesamtbreite einer Leiste 33 der Dicke einer Dämmschicht 34. In Fig. 8 ist die Gesamtbreite einer Leiste 35 geringer als die Dicke einer Dämmschicht 36. In Fig. 5 sind die Schenkel 37, 38 einer Leiste 39 auf den Außenseiten der Deckplatten 3, 4 angeordnet, während in Fig. 6 der Schenkel 37 einer Leiste 40 auf der Außenseite der einen Sperrholzplatte 5 und der andere Schenkel 38 auf der Innenseite der anderen Sperrholzplatte 6 angeordnet ist. In entsprechender weise sind die Schenkel der Leisten 33, 35 und die Schenkel 37, 38 der Leisten 39, 40 mit den homologen Sperrholzplatten der nicht dargestellten zweiten Bauplatte verbunden.FIGS. 4-6 and 8 show further examples of the arrangement of a double T-shaped bar. These examples have advantages for the intended use cases. In FIG. 4, the overall width of a strip 33 corresponds to the thickness of an insulation layer 34. In FIG. 8, the overall width of a strip 35 is less than the thickness of an insulation layer 36. In FIG. 5, the legs 37, 38 of a strip 39 are on the outside the cover plates 3, 4, while in FIG. 6 the leg 37 of a strip 40 is arranged on the outside of one plywood board 5 and the other leg 38 on the inside of the other plywood board 6. In a corresponding manner, the legs of the strips 33, 35 and the legs 37, 38 of the strips 39, 40 are connected to the homologous plywood panels of the second building board, not shown.
In den Figuren 3 und 7 sind analog zu den Fig. 4 und 8 Vollholzleisten 41 , 42 dargestellt, die zwischen den Sperrholzplatten 3, 4 angeordnet sind. Die Vollholzleiste 41 hat die Dicke einer Dämmschicht 34' und ist mit beiden Sperrholzplatten 3, 4 verklebt. Die Vollholzleiste 42 hat eine geringere Dicke als die Dämmschicht 34' und ist mit der Sperrholzplatte verklebt. Auch hier sind die Leisten 41 , 42 in entsprechender Weise mit der nicht dargestellten zweiten Bauplatte verklebbar.In FIGS. 3 and 7, solid wood strips 41, 42 are shown analogously to FIGS. 4 and 8, which are arranged between the plywood panels 3, 4. The solid wood strip 41 has the thickness of an insulation layer 34 'and is with two plywood panels 3, 4 glued. The solid wood strip 42 has a smaller thickness than the insulation layer 34 'and is glued to the plywood panel. Here, too, the strips 41, 42 can be glued in a corresponding manner to the second building board, not shown.
In Fig. 9 ist eine weitere Leiste 43 als Bestandteil einer Verbindungsvorrichtung dargestellt. Die Leiste 43 ist im Querschnitt U-förmig mit einer Basis 44 und zwei Schenkeln 45, 46 ausgebildet, wobei die Basis 44 der Dicke der Sperrholzplatten (3 - 6) entsprechende Überstände 47, 48 über die Schenkel 45, 46 aufweist.9 shows a further strip 43 as part of a connecting device. The strip 43 is U-shaped in cross section with a base 44 and two legs 45, 46, the base 44 having projections 47, 48 corresponding to the thickness of the plywood panels (3-6) over the legs 45, 46.
Wie die Fig. 10 zeigt, kann mit einer derartigen Leiste 43 eine Verbindungsvorrichtung 49 zwischen zwei rechtwinklig miteinander zu verbindenden Bauplatten 1 und 2, die ähnlich denen der Fig. 1 ausgebildet sind, geschaffen werden. Die Leiste 43 ist in die Bauplatte 1 derart eingefügt, dass sie mit ihren Schenkeln 45, 46 an den Innenseiten der Sperrholzplatten 3, 4 anliegt. Diese Schenkel sind mit diesen Platten verklebt. Ferner ist die Basis 44 mit der Deckplatte 6 der zweiten Bauplatte 2 mittels Klebmittelaufträgen, wie des Klebmittelauftrags 50, verklebt.As FIG. 10 shows, a strip 43 of this type can be used to create a connecting device 49 between two building panels 1 and 2 which are to be connected at right angles and which are similar to those in FIG. 1. The strip 43 is inserted into the building board 1 in such a way that its legs 45, 46 rest against the inside of the plywood boards 3, 4. These legs are glued to these plates. Furthermore, the base 44 is glued to the cover plate 6 of the second building board 2 by means of adhesive applications, such as the adhesive application 50.
Ferner kann eine derartige Leiste auch als Kantenabschlussleiste 43' eingesetzt werden, die in die zweite Bauplatte 2 eingefügt ist. Diese Kantenabschlussleiste ist mit ihrer Basis 44' und den Schenkeln 45', 46' wie die Leiste 43 in die Bauplatte eingesetzt. Zusätzlich kann zur Festigkeitserhöhung eine durch die Sperrholzleiste 5, die Schenkel 45', 46' und die Sperrholzplatte 6 durchgeführte Schraube 51 in die Basis 44 eingeschraubt werden. Die Leisten 43, 43' sind außenbündig bzw. innenbündig mit den Bauplatten 1 , 2 angeordnet. Die Bauplatten 1 , 2 können innen noch mit einer Gipsputzschicht oder mit Gipskartonplatten 52 versehen sein.Furthermore, such a strip can also be used as an edge sealing strip 43 'which is inserted into the second building board 2. This edge termination strip is inserted with its base 44 'and the legs 45', 46 'like the strip 43 into the building board. In addition, to increase the strength, a screw 51 passed through the plywood strip 5, the legs 45 ', 46' and the plywood board 6 can be screwed into the base 44. The strips 43, 43 'are arranged flush or flush with the building boards 1, 2. The building boards 1, 2 can also be provided on the inside with a gypsum plaster layer or with plasterboard 52.
Die Fig. 11 zeigt ein weiteres Anwendungsbeispiel im Bereich einer Wand-Dach- Verbindung. Eine Verbindungsvorrichtung aus einer Vollholzleiste 53 und einer im Querschnitt keilförmigen Leiste 54 sorgt für die Verbindung einer Wand 55 mit einem Dach 55, die beide aus Bauplatten der Fig. 1 bestehen. Die Leiste 53 ist mit zugeordneten Sperrholzplatten der Wand 55 verklebt, während die Leiste 54 mit der Leiste 53 und einer Sperrholzplatte des Dachs 56 verklebt sein kann. Eine Leiste 43' ist als Kantenabschluss für das Dach 56 ähnlich wie in Fig. 10 eingesetzt. Mit derartigen Wandplatten, Dachplatten und Verbindungsvorrichtungen können ganze Häuser, auch mehrstöckige Häuser, aufgebaut werden, ohne dass es eines gesonderten Stützgerüstes als Skelett für den Hausaufbau bedarf. Dies gilt auch für den Dachaufbau, bei dem gesonderte Dach- und Firstbalken nicht mehr erforderlich sind. Die damit erreichbare Stabilität des Hauses erklärt sich auch durch den Scheibeneffekt der miteinander verbundenen Bauplatten. 11 shows a further application example in the area of a wall-roof connection. A connecting device from a solid wood strip 53 and one in Cross-section wedge-shaped bar 54 ensures the connection of a wall 55 with a roof 55, both of which consist of building boards of FIG. 1. The bar 53 is glued to associated plywood panels of the wall 55, while the bar 54 can be glued to the bar 53 and a plywood panel of the roof 56. A strip 43 'is used as an edge closure for the roof 56 similar to that in FIG. 10. With such wall panels, roof panels and connecting devices, entire houses, including multi-storey houses, can be built without the need for a separate support structure as a skeleton for building the house. This also applies to the roof structure, where separate roof and ridge beams are no longer required. The stability of the house that can be achieved with this is also explained by the pane effect of the interconnected building boards.
