Abstract

The method uses at least two building plate components (2,3) which are so displaced in relation to one another and connected to form a building plate (1), that through the displacement on three side edges a stage rabbet (4,5) is produced. The components are again so arranged in relation to one another that on a fourth side edge the second component (3) extends over the first (2). The components are adhered to one another to form a building plate. The building plate along three side edges has a stage rabbet evolving from the first component and along a fourth side edge a stage rabbet evolving from the second component.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Bauplatte, insbesondere zur Trittschall- und/oder Wärmedämmung, mit im wesentlichen rechteckiger Grundfläche und einem Stufenfalz, zumindest entlang einer Seitenkante. Ferner betrifft die Erfindung eine Bauplatte nach dem Oberbegriff des Anspruches 5.The present invention relates to a method for producing a building board, in particular for impact sound and / or thermal insulation, with an essentially rectangular base area and a step fold, at least along one side edge. The invention further relates to a building board according to the preamble of claim 5.

Bei der Verlegung von Bauplatten, insbesondere zur Wärmedämmung oder für Trittschall sind mehrere Verbindungstechniken bekannt, um die Bauplatten seitlich aneinanderzusetzen bzw. zu verbinden. In einfachster Weise werden die Bauplatten an ihren seitlichen Kanten stumpf gestoßen. Eine unzureichende Maßhaltigkeit oder ein nachträgliches Schwinden der einzelnen Bretter führt jedoch zu einer meist unerwünschten, durchlässigen Fuge. War eine Bauplatte mit stumpfem Stoß aus technischen Gründen als nicht ausreichend erachtet, so mußte bislang auf eine Bauplatte mit Nut und Feder zugegriffen werden. Das Profil von Nut und Feder ist allerdings nicht nur verhältnismäßig aufwendig in der Herstellung, sondern auch in der Handhabung und beim Transport relativ empfindlich. Ferner ist in nachteiliger Weise von dieser Schwäche der Nutwangen die gesamte Stabilität einer Nut und Federverbindung abhängig.When laying building boards, in particular for thermal insulation or impact sound, several connection techniques are known in order to connect or connect the building boards laterally. In the simplest way, the building boards are butted against their lateral edges. However, insufficient dimensional accuracy or subsequent shrinkage of the individual boards leads to a mostly undesirable, permeable joint. For technical reasons, a building board with a butt joint was not considered sufficient, so far a building board with tongue and groove had to be accessed. The tongue and groove profile is not only relatively complex to manufacture, but also relatively sensitive to use and transport. Furthermore, the overall stability of a tongue and groove connection is disadvantageously dependent on this weakness of the groove cheeks.

Weiterhin ist es bekannt, zwei Bretter mit einem Falz zu verbinden. Diese auch als halbe Spundung, gefalzte Fuge oder Überfälzung bezeichnete Verbindung ist eine einfache und stabile Verbindung. Da im Verbindungsbereich die Brettflächen beweglich übereinandergreifen, führt ein Schwinden der einzelnen Bretter nicht zu einer durchlässigen Fuge. Die hierbei erforderliche rechtwinklige Auskehlung wurde bislang durch eine aufwendige Kantenfräsung erzielt.It is also known to connect two boards with a fold. This connection, also known as a half bung, folded joint or rebate, is a simple and stable connection. Since the board surfaces move flexibly one above the other in the connection area, shrinking of the individual boards does not lead to a permeable joint. The right-angled grooving required here has so far been achieved by complex edge milling.

Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Verfahren zur einfacheren Herstellung einer Bauplatte und eine einfach zu handhabende Bauplatte der eingangs genannten Art anzugeben.It is therefore an object of the present invention to provide a method for simpler manufacture of a building board and an easy-to-use building board of the type mentioned at the outset.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens zwei Bauplattenelemente derart versetzt zueinander zu einer Bauplatte verbunden werden, daß durch die Versetzung an drei Seitenkanten ein Stufenfalz entsteht. Eine Bauplatte die nach diesem Verfahren hergestellt wird, zeichnet sich dadurch aus, daß ein erstes Bauplattenelement ein zweites Bauplattenelement der Bauplatte entlang dreier Seitenkanten überragt. Ein derartiges Verfahren erübrigt eine Kantenabfräßung zur Erzeugung der Ausklinkung des Stufenfalzes. Mit einer Bauplatte, deren unteres, erstes Bauplattenelement das obere, zweite Bauplattenelement entlang drei Seitenkanten überragt, ist sowohl eine durchlässige Fuge vermieden als auch ein besonders flexibler Einsatzbereich gegeben. So liegen die Bauplatten vollflächig seitlich aneinander an, wenn jeweils jede zweite Bauplatte mit der oberen Grundfläche nach unten umgedreht angeordnet ist. Bei gleicher Lageorientierung der Bauplatten nebeneinander erzeugen die auf gleicher Höhe liegenden Aussparungen bzw. Auskehlungen von zwei Seitenkanten benachbarter Bauplatten eine gemeinsame größere Nut bzw. Auskehlung in der eine Nagelleiste Platz findet.This object is achieved in that at least two building board elements are offset from one another to form a building board in such a way that a step fold is created by the displacement on three side edges. A building board which is produced by this method is characterized in that a first building board element projects beyond a second building board element of the building board along three side edges. Such a method eliminates the need to mill the edges to produce the notch of the step fold. With a building board, the lower, first building board element of which projects above the upper, second building board element along three side edges, both a permeable joint is avoided and a particularly flexible area of application is provided. Thus, the building boards lie against one another laterally over their entire surface, if every second building board is arranged with the upper base surface turned downward. With the same orientation of the building boards next to each other, the recesses or grooves of two side edges of adjacent building boards lying at the same height create a common larger groove or groove in which a nail bar can be placed.

In besonders einfacher Weise wird der Stufenfalz an den wenigstens drei Seitenkanten dadurch gebildet, daß zwei quaderförmige Bauplattenelemente eine unterschiedliche Grundflächengröße aufweisen.In a particularly simple manner, the step fold is formed on the at least three side edges by the fact that two cuboidal building board elements have a different base area size.

In weiterer vorteilhafter Ausgestaltung der Erfindung weist die Bauplatte an einer vierten, einen gegenüber den drei anderen Seitenkanten versetzten Stufenfalz auf. Dies bedeutet, daß die Wange des Stufenfalzes an der vierten Seitenkante auf gleicher Höhe mit den Auskehlungen der drei übrigen Seitenkanten angeordnet ist. Somit sind zwei gegenüberliegende Seitenkanten mit auf gleicher Höhe ausgerichteten Stufenfalz und die beiden anderen gegenüberliegenden Seitenkanten mit zueinander entgegengesetzt ausgerichteten Stufenfalz versehen. Dies entspricht den praktischen Anforderungen beim Verlegen von Bauplatten, da bei der Notwendigkeit von Nagelleisten diese in der Regel parallel zueinander in einer Längsrichtung verlaufen.In a further advantageous embodiment of the invention, the building board has a step fold on a fourth, offset with respect to the three other side edges. This means that the cheek of the step fold on the fourth side edge is level with the fillets of the three other side edges is arranged. Thus, two opposite side edges are provided with a step fold aligned at the same height and the two other opposite side edges are provided with a step fold oriented opposite to one another. This corresponds to the practical requirements when laying building boards, since if nail strips are required, they usually run parallel to one another in a longitudinal direction.

Vorzugsweise werden die zwei Bauplattenelemente zu einer Bauplatte verklebt. Dies ist sowohl eine sichere als auch kostengünstige Verbindungstechnik. Bei Ausbildung einer einteiligen Bauplatte würde zudem in nachteiliger Weise durch die Fräsung bedingter Abfall entstehen.The two building board elements are preferably glued to form a building board. This is both a safe and inexpensive connection technology. If a one-piece building board were formed, waste would also arise in a disadvantageous manner as a result of the milling.

In vorteilhafter Ausgestaltung der Erfindung weist die Bauplatte eine Gesamtlänge von 1,2 m und eine Gesamtbreite von 0,8 m auf. Mit diesem auf Europaletten abgestimmten Abmessungen der Bauplatte ist eine sehr gute Transportierbarkeit und durch die Europalette gleichzeitig ein guter Kantenschutz für die aufeinander gestapelten Bauplatten gegeben. Ferner ist ein derartiges Format sehr einfach zu handhaben.In an advantageous embodiment of the invention, the building board has a total length of 1.2 m and a total width of 0.8 m. This size of the building board, which is matched to Euro pallets, means that it can be easily transported and, at the same time, the Euro pallet provides good edge protection for the building boards stacked on top of one another. Such a format is also very easy to use.

Die erfindungsgemäßen Bauplatten mit gleichem Format und gleichem Verbindungsfalz können in den unterschiedlichsten Bereichen Verwendung finden. Durch die Einheitlichkeit aller Bauplatten ist der Logistikaufwand, Frachtaufwand, Lageraufwand und Kapazität, Bereithaltungskosten, Baustellenfläche, Beratungsaufwand und Verarbeitungsaufwand gegenüber konventionellen Bauplatten stark reduziert. Die Verbindung mit Stufenfalz ist zudem auch für Heimwerker, denen nur einfaches Werkzeug zur Verfügung steht, gut zu handhaben. Überdies sind die Bauplatten mit Verbindungsfalz in ihrer Kantenstabilität denen mit Federnutsystem deutlich überlegen.The building boards according to the invention with the same format and the same connecting fold can be used in a wide variety of areas. Due to the uniformity of all building boards, the logistics effort, freight effort, storage effort and capacity, maintenance costs, construction site space, consulting effort and processing effort are greatly reduced compared to conventional building boards. The connection with a rebate is also easy to handle for do-it-yourselfers who only have simple tools available. In addition, the building boards with a joint rebate are clearly superior to those with a tongue groove system in terms of their edge stability.

Die Fig. 1 zeigt eine im wesentlichen rechteckige Bauplatte 1, die sich aus zwei übereinanderliegenden Bauplattenelementen 2,3 zusammensetzt. Die beiden Bauplattenelemente 2,3 sind derart zueinander versetzt zu einer Bauplatte 1 miteinander verbunden, daß an allen vier Seitenkanten der Bauplatte 1 ein Stufenfalz entsteht. Durch die Quaderform der beiden Bauplattenelemente 2,3 ist der Stufenfalz - wie aus Fig. 2 und 3 hervorgeht -, mit einer überstehenden Wange 4,6 und einer rechtwinklingen Auskehlung 5,7 versehen.1 shows an essentially rectangular building board 1, which is composed of two building board elements 2, 3 lying one above the other. The two building board elements 2, 3 are connected to one another to form a building board 1 such that a step fold is formed on all four side edges of the building board 1. Due to the cuboid shape of the two building board elements 2, 3, the step fold - as can be seen from FIGS. 2 and 3 - is provided with a projecting cheek 4,6 and a right-angled groove 5.7.

Im dargestellten Ausführungsbeispiel weist das untere, erste Bauplattenelement 2 eine größere Grundfläche auf als das obere, zweite Bauplattenelement 3. Hierbei sind die Längen der Bauplattenelemente 2,3 gleich und die Breite des Bauplattenelementes 2 größer als die des Bauplattenelementes 3. Aus Gründen der Handhabbarkeit und der Transportierbarkeit weist die Bauplatte 1 vorzugsweise eine Gesamtlänge LG von etwa 1,2 m und eine Gesamtbreite BG von etwa 0,8 m auf. Beide Bauplattenelemente 2,3 sind gleich dick (etwa 2,5 cm), so daß sich eine Gesamtstärke der Bauplatte 1 von 5 cm ergibt. Die Länge jedes Bauplattenelementes 2,3 beträgt etwa 1,16 m und die Breite des breiteren Bauplattenelementes 2 beträgt etwa 0,8 m und die des schmäleren Bauplattenelementes 3 etwa 0,72 m. Die Bauplattenelemente 2,3 sind derart miteinander verbunden, daß das breitere Bauplattenelement 2 an drei Seitenkanten eine um etwa 4 cm überstehende Wange bildet, und das obere Bauplattenelement 3 - wie vor allen Dingen aus Fig. 3 hervorgeht - eine überstehende Wange an einer Seitenkante (in Fig. 1 oben) von ebenso etwa 4 cm bildet.In the exemplary embodiment shown, the lower, first building board element 2 has a larger base area than the upper, second building board element 3. The lengths of the building board elements 2, 3 are the same and the width of the building board element 2 is greater than that of the building board element 3. For reasons of manageability and In terms of portability, the building board 1 preferably has an overall length L G of approximately 1.2 m and an overall width B G of approximately 0.8 m. Both building board elements 2, 3 are of equal thickness (about 2.5 cm), so that the overall thickness of building board 1 is 5 cm. The length of each building board element 2, 3 is about 1.16 m and the width of the wider building board element 2 is about 0.8 m and that of the narrower building board element 3 is about 0.72 m. The building board elements 2, 3 are connected to one another in such a way that the wider building board element 2 forms a cheek that protrudes by about 4 cm on three side edges, and the upper building board element 3 - as can be seen above all from FIG. 3 - a projecting cheek on one side edge ( in Fig. 1 above) also of about 4 cm.

Die vorzugsweise aus Holz, einem holzähnlichen Material oder anderem Material bestehenden Bauplattenelemente 2,3 werden bevorzugt miteinander verklebt, es sind jedoch auch andere Verbindungstechniken, je nach Material der Bauplatte 1, denkbar.The building board elements 2, 3, which are preferably made of wood, a wood-like material or another material, are preferably glued to one another, but other connection techniques are also conceivable, depending on the material of the building board 1.

Die Fig. 4 zeigt mehrere gleichsinnig nebeneinander gesetzte Bauplatten 1, deren seitliche Wangen auf gleicher Höhe aneinanderstoßen, so daß die auf gleicher Höhe angeordneten rechtwinkligen Auskehlungen gemeinsam eine Nut erzeugen, in der eine Nagelleiste 8 aufgenommen ist. Eine derartige Verlegung der Bauplatten 1 kann beispielsweise zur Trittschalldämmung vorteilhaft sein, wie sie üblicherweise unter Holzdielen, Böden oder ähnlichem angewendet wird. Mit der einfach eingelegten Nagelleiste 8 ist eine vollflächige Dämmwirkung unter Ausnutzung der Dämmöglichkeit auf der Gesamthöhe erreicht. Ferner ist es dabei möglich die Dielenbretter zu befestigen.4 shows several building boards 1 placed in the same direction next to one another, the side cheeks of which abut one another at the same height, so that the right-angled grooves arranged at the same height jointly produce a groove in which a nail strip 8 is received. Such laying of the building boards 1 can be advantageous, for example, for impact sound insulation, as is usually used under wooden floorboards, floors or the like. With the simply inserted nail strip 8, a full-surface insulation effect is made using the insulation possibility at the entire height reached. It is also possible to attach the planks.

Bei der in Fig. 5 dargestellten Verlegeweise der Bauplatten 1 ist jede zweite Bauplatte 1 umgedreht angeordnet. Dadurch greifen entlang der Längsseitenkanten die jeweilige Wange der Bauplatte 1 in die jeweilige Auskehlung der benachbarten Bauplatte 1 ein. Es entsteht so eine durchgehende Fläche ohne Durchgangsfuge.In the way of laying the building boards 1 shown in FIG. 5, every other building board 1 is arranged upside down. As a result, the respective cheek of the building board 1 engages in the respective groove of the neighboring building board 1 along the longitudinal side edges. This creates a continuous surface without a gap.

Die Fig. 6 zeigt eine vergrößerte Darstellung der ineinandergreifenden Verbindungsfalze zweier Bauplatten 1, wie sie beispielsweise bei einer Verlegung nach Fig. 5 entlang der Längsseitenkanten oder entlang der Breitenseitenkanten der Bauplatten 1 vorliegt.FIG. 6 shows an enlarged illustration of the interlocking connecting folds of two building boards 1, as is present, for example, when laying according to FIG. 5 along the long side edges or along the wide side edges of the building boards 1.

In Fig. 7 ist ein vergrößerter Ausschnitt der Verbindungsstelle zwischen zwei Bauplatten 1 dargestellt, bei Verwendung einer Nagelleiste 8, wie bereits mit Fig. 4 erläutert. Eine derartige Verlegung der Bauplatten kann zur Trittschalldämmung unter Böden 9 oder zur Wärmedämmung an Wandverkleidungen 9 durchgeführt werden. Vorzugsweise ist die Nagelleiste 8 in ihren Querschnittsabmessungen etwas kleiner als die gebildete Nut zwischen den beiden Bauplatten 1 zu dimensionieren, damit Fertigungsungenauigkeiten z.B. bei leichter Krümmung der Nagelleiste 8 oder nachträglichem einseitigen Schwund der Nagelleiste 8 ausgeglichen werden können.FIG. 7 shows an enlarged section of the connection point between two building boards 1 when using a nail bar 8, as already explained with FIG. 4. Such laying of the building boards can be carried out for impact sound insulation under floors 9 or for thermal insulation on wall cladding 9. The cross-sectional dimensions of the nail strip 8 are preferably to be dimensioned somewhat smaller than the groove formed between the two building boards 1, so that manufacturing inaccuracies e.g. with slight curvature of the nail bar 8 or subsequent unilateral shrinkage of the nail bar 8 can be compensated.

Fig. 8 zeigt mehrere nebeneinander verlegte Bauplatten 1, wobei deutlich wird, daß ein derartiger Verbindungsfalz entlang der vier Seitenkanten ebenso einzupassen ist, wenn Platten quer zur Legerichtung angelegt werden. Bei der gewählten Dimensionierung der Bauplatten 1 können entlang zwei längsverlegter Bauplatten 1 genau drei Bauplatten 1 quer dazu angelegt werden.Fig. 8 shows several building boards 1 laid side by side, it being clear that such a connecting fold along the four side edges is also to be fitted if boards are laid transversely to the laying direction. In the selected dimensioning of the building boards 1, exactly three building boards 1 can be placed transversely thereto along two longitudinally laid building boards 1.

Die Grundflächengröße und die Plattenstärke können auch anders als hier vorgeschlagen bemessen sein, je nach den Erfordernissen und dem Einsatzzweck der Bauplatte. Weiterhin ist es möglich, statt des holzartigen Materials die gesamte Bauplatte 1 oder nur eines der Bauplattenelemente 2,3 aus einem anderen Material oder Dämmstoff herzustellen. So ist ein Sandwich-Mehrschichtaufbau möglich, bei dem beispielsweise zwischen zwei Holzplatten ein anderes Dämmaterial eingelegt ist. Dieses Herstellungsverfahren der Bauplatten und der Verbindungsfalz kann für Gipsfaserplatten ebenso angewandt werden. Der Stufenfalz entlang zwei gegenüberliegenden Seitenkanten kann hierbei alternativ mit einem stumpfen Stoß ausgeführt werden. Auch kann das Bauplattenelement 3 so bemessen sein, daß es in der Länge derart verkürzt ist, daß die bisherige, obere Wange 6 durch eine untere Wange 4 (in Fig. 3) auf gleicher Höhe wie die Wangen 4 der drei anderen Seitenkanten ausgebildet ist. In einer weiteren Variante kann das obere Bauplattenelement 3 auf beiden Breitenseiten das Bauplattenelement 2 überragend ausgebildet sein, so daß die in Fig. 3 dargestellte Wange 4 des unteren Bauplattenelementes 2 durch eine obere Wange 6 ersetzt wird.The base size and the plate thickness can also be dimensioned differently than suggested here, depending on the requirements and the purpose of the building board. Furthermore, it is possible to produce the entire building board 1 or only one of the building board elements 2, 3 from a different material or insulating material instead of the wood-like material. A sandwich multi-layer construction is possible, for example, in which another insulating material is inserted between two wooden panels. This method of manufacturing the building boards and the joint fold can also be used for gypsum fiber boards. The step fold along two opposite side edges can alternatively be carried out with a butt joint. The building board element 3 can also be dimensioned such that it is shortened in length in such a way that the previous upper cheek 6 is formed by a lower cheek 4 (in FIG. 3) at the same height as the cheeks 4 of the three other side edges. In a further variant, the upper building board element 3 can be designed to protrude on both sides of the building board, so that the cheek 4 of the lower building board element 2 shown in FIG. 3 is replaced by an upper cheek 6.
