Description

Die Erfindung betrifft eine schallschluckende Röhrenspanplatte, die an ihrer Vorderseite, also raumseitig, parallel zu ihren Röhren verlaufende und bis in diese Röhren reichende Schlitze aufweist und bei der die Röhren durch querverlaufende Verbindungskanäle miteinander verbunden sind.The invention relates to a sound-absorbing particle board which has slots on its front side, that is to say on the room side, which extend parallel to its tubes and extend into these tubes and in which the tubes are connected to one another by transverse connecting channels.

Aus der deutschen Patentschrift 27 44 382 ist eine derartige, zur Verwendung als Wand- oder Deckenverkleidung bestimmte Röhrenspanplatte bekannt, bei der die die Röhren untereinander verbindenden Verbindungskanäle Bohrungen sind, die etwa mittig zwischen der Plattenvorderseite und der Plattenrückseite verlaufen. Die Herstellung derartiger Platten ist wegen dieser nachträglich vorzunehmenden Bohrungen relativ aufwendig. Zudem hat sich gezeigt, daß die Variation der Dämmwirkung derartiger Platten begrenzt ist.From German Patent Specification 27 44 382, such a chipboard panel intended for use as wall or ceiling cladding is known, in which the connecting channels connecting the tubes to one another are bores which run approximately centrally between the front side of the panel and the rear side of the panel. The production of such plates is relatively complex because of these holes to be made later. In addition, it has been shown that the variation in the insulation effect of such panels is limited.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung einer schallschluckenden Röhrenspanplatte der eingangs beschriebenen Art zu vereinfachen und deren Variationsmöglichkeiten hinsichtlich der Dämpfung unterschiedlicher Frequenzen zu vergrößern.The invention has for its object the manufacture of a sound-absorbing chipboard be the beginning to simplify the type described and to increase their variation possibilities with regard to the attenuation of different frequencies.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die einzelnen Röhren durch von der Rückseite der Platte ausgehende Ausnehmungen miteinander verbunden sind, die vorzugsweise durch eine Furnierlage abgedeckt sind. Diese Ausnehmungen, die vorzugsweise als Querschlitze ausgebildet sind, aber auch als schräg oder kurvenförmig verlaufende Schlitze, darüber hinaus aber auch Ausnehmungen sein können, die in Draufsicht beliebig, beispielsweise kreis- oder elliptenförmig ausgebildet sein können, bieten gegenüber querverlaufenden Bohrungen den Vorteil, daß sie einfacher, billiger und variabler herstellbar sind, wodurch die Schallabsorption in einfacher Weise dem gewünschten Frequenzbereich angepaßt werden kann, insbesondere den mittleren Frequenzen.This object is achieved in that the individual tubes are connected to each other by recesses extending from the back of the plate, which are preferably covered by a veneer layer. These recesses, which are preferably designed as transverse slots, but also as oblique or curved slots, but can also be recesses that can be arbitrary in plan view, for example circular or elliptical, offer the advantage over transverse holes that they are easier, cheaper and more variable to produce, so that the sound absorption can be easily adapted to the desired frequency range, in particular the medium frequencies.

Vorgenannte Ausnehmungen können unterschiedliche Tiefen aufweisen, sie sind jedoch vorzugsweise so tief, daß sie bis etwa in die Mitte der benachbarten Röhren reichen. Sind die Ausnehmungen schlitzförmig ausgebildet, so vorzugsweise in einer Breite, die etwa einem Drittel der Röhrendurchmesser entspricht. Der Abstand der einzelnen Schlitze untereinander in Plattenlängsrichtung beträgt dabei vorzugsweise etwa 100 mm.The aforementioned recesses can have different depths, but they are preferably so deep that they reach approximately in the middle of the adjacent tubes. If the recesses are slot-shaped, then preferably in a width that corresponds to approximately one third of the tube diameter. The distance between the individual slots in the longitudinal direction of the plate is preferably about 100 mm.

Die die einzelnen Röhren miteinander verbindenden Ausnehmungen weisen vorzugsweise einen im wesentlichen rechteckigen Querschnitt auf. Dies gilt unabhängig davon, wie sie in Draufsicht geformt sind.The recesses connecting the individual tubes preferably have an essentially rectangular cross section. This applies regardless of how they are shaped in plan view.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Röhrenspanplatte weist die furnierte Rückwand bis ins Röhreninnere reichende Längsschlitze auf, die für eine Kommunikation zwischen dem Röhreninneren und dem Zwischenraum zwischen der Röhrenspanplatte und einer mit dieser zu verschalenden Wand sorgen. Dieser Zwischenraum kann zur weiteren Schalldämmung, insbesondere der hohen Frequenzen, mit Mineralwolle ausgefüllt sein. Die rückseitigen Längsschlitze sind vorzugsweise in Längsrichtung unterbrochen, werden also vorzugsweise von einzelnen Längsschlitz-Abschnitten gebildet, mit dem Vorteil, daß vorgenannte Kommunikation möglich ist, ohne daß hierdurch eine Entstabilisierung der Röhrenspanplatte in Kauf zu nehmen wäre. Die einzelnen Längsschlitz-Abschnitte sind dabei vorzugsweise länger, als der lichte Abstand der Querschlitze voneinander, vorzugsweise aber kürzer als der doppelte Abstand dieser Querschlitze.In a preferred embodiment of the chipboard according to the invention, the veneered rear wall has longitudinal slots extending into the inside of the tube, which ensure communication between the inside of the tube and the space between the chipboard and a wall to be clad with it. This space can be filled with mineral wool for further sound insulation, especially the high frequencies. The rear longitudinal slots are preferably interrupted in the longitudinal direction, that is to say are preferably formed by individual longitudinal slot sections, with the advantage that the aforementioned communication is possible without the need to accept destabilization of the chipboard. The individual longitudinal slot sections are preferably longer than the clear distance between the transverse slots, but preferably shorter than twice the distance of these transverse slots.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Röhrenspanplatte ist an der Rückseite jede vierte Röhre längsgeschlitzt, d.h. mit einem Längsschlitz bzw. mehreren, miteinander fluchtenden Längsschlitz-Abschnitten versehen. Der Abstand der miteinander fluchtenden Längsschlitz-Abschnitte an der Plattenrückseite entspricht vorzugsweise der jeweiligen Länge der Längsschlitze, wobei die Unterbrechungen der einzelnen Längsschlitze durchgehend über die Breite der Röhrenspanplatte verlaufen können, es wäre jedoch auch möglich, die einzelnen Längsschlitz-Abschnitte so anzuordnen, daß jeweils rechts und links neben einem Längsschlitz-Abschnitt ein dem benachbarten Längsschlitz unterbrechender Bereich vorgesehen ist, das heißt, daß die parallelen Längsschlitz-Abschnitte versetzt zueinander angeordnet sind.In a preferred embodiment of the chipboard according to the invention, every fourth tube is slit longitudinally on the back, i.e. provided with a longitudinal slot or a plurality of aligned longitudinal slot sections. The distance between the aligned longitudinal slot sections on the back of the plate preferably corresponds to the respective length of the longitudinal slots, the interruptions of the individual longitudinal slots running continuously across the width of the chipboard, but it would also be possible to arrange the individual longitudinal slot sections so that each to the right and left of a longitudinal slot section, an area interrupting the adjacent longitudinal slot is provided, that is to say that the parallel longitudinal slot sections are arranged offset to one another.

An der Vorderseite der erfindungsgemäßen Röhrenspanplatte können die mit den Röhren der Röhrenspanplatte kommunizierenden Längsschlitze in bekannter Weise durchgehend vorgesehen sein, vorzugsweise für jede zweite dieser Röhren ein Längsschlitz.On the front of the chipboard according to the invention can communicate with the tubes of the chipboard Longitudinal slots can be provided continuously in a known manner, preferably one longitudinal slot for every second of these tubes.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Röhrenspanplatte ist in denjenigen Röhren, denen an der Rückseite ein Längsschlitz zugeordnet ist, auch an der Vorderseite ein Längsschlitz zugeordnet. Es ist vorteilhaft, an der Rückseite der Röhrenspanplatte nur halb so viele, mit jeweils einer Röhre kommunizierende Längsschlitze vorzusehen als an der Vorderseite. Ist für eine Röhre sowohl an der Vorderseite als auch an der Rückseite der Röhrenspanplatte ein Längsschlitz vorgesehen, so ist es möglich, diese beiden Schlitze zueinander fluchtend auszurichten. Röhrenspanplatten als solche sind in den DIN-Blättern 68 762 und 68 764 beschrieben.In a preferred embodiment of the tubular chipboard according to the invention, a longitudinal slot is also assigned on the front in those tubes to which a longitudinal slot is assigned on the rear side. It is advantageous to provide only half as many longitudinal slots, each communicating with one tube, on the back of the tube chipboard than on the front. If a longitudinal slot is provided for a tube both on the front side and on the rear side of the chipboard, it is possible to align these two slots in alignment with one another. Chipboard panels as such are described in DIN sheets 68 762 and 68 764.

Die erfindungsgemäße Röhrenspanplatte wird vorzugsweise so hergestellt, daß sie zunächst in an sich bekannter Weise als Röhrenspanplatte im Strangpreßverfahren hergestellt wird. In die Rückseite der Platte werden dann Ausnehmungen so tief eingeschnitten, daß die Röhren mindestens teilweise angeschnitten werden. Danach kann die Spanplatte an der Rückseite abgedeckt und vorzugsweise an der Vorderseite, furniert und an der Vorderseite entlang mindestens einiger Röhren bis in diese hinein aufgeschlitzt, wobei eine rückseitige Längsschlitzung vorzugsweise nur abschnittweise erfolgt.The chipboard according to the invention is preferably produced in such a way that it is first produced in a manner known per se as a chipboard in the extrusion process. In the back of the plate recesses are then cut so deep that the tubes are cut at least partially. Then the chipboard can be covered on the back and preferably veneered on the front and slit on the front along at least some tubes into it, with a longitudinal slit on the back preferably only in sections.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachfolgenden Beschreibung bevorzugter Ausführungsformen im Zusammenhang mit der Zeichnung. In der Zeichnung zeigen jeweils schematisch und in geschnittener perspektivischer Darstellung:

  • Fig. 1 eine Ausführungsform der erfindungsgemäßen Röhrenspanplatte, montiert auf einem Lattenrost,
  • Fig. 2 die in Fig. 1 dargestellte Röhrenspanplatte um 180° gedreht, d.h. mit nach oben weisender Rückseite und
  • Fig. 3 eine andere Ausführungsform der erfindungsgemäßen Röhrenspanplatte mit nach oben weisender Rückseite.
Further details, features and advantages of the invention result from the claims and the following description of preferred embodiments in connection with the drawing. The drawings show schematically and in a sectional perspective representation:
  • 1 shows an embodiment of the chipboard according to the invention, mounted on a slatted base,
  • Fig. 2 rotated the chipboard shown in Fig. 1 by 180 °, ie with the rear facing upwards and
  • Fig. 3 shows another embodiment of the chipboard according to the invention with the rear facing upwards.

Die in den Figuren 1 und 2 dargestellte Röhrenspanplatte 1 mit einer Stärke von 25 - 30 mm ist unter Zwischenlage eines aus vertikalen Latten 2 und horizontalen Latten 3 bestehenden Lattenrostes an einer Wand 4 montiert. Sie weist durchgehende, parallel zueinander verlaufende Röhren 5, 6, 7 auf, die einen Innendurchmesser von 12 - 15 mm haben, und ist beidseitig mit einem Furnier 8, 9 versehen.The tubular chipboard 1 shown in FIGS. 1 and 2 with a thickness of 25-30 mm is mounted on a wall 4 with the interposition of a slatted frame consisting of vertical slats 2 and horizontal slats 3. It has continuous tubes 5, 6, 7 running parallel to one another, which have an inner diameter of 12-15 mm, and is provided on both sides with a veneer 8, 9.

Der Lattenrost kann auch nur aus rechtwinklig zu den Röhren 5, 6, 7 verlaufenden Latten bestehen - bei der dargestellten Ausführungsform also nur aus horizontalen Latten 3.The slatted frame can also consist only of slats running at right angles to the tubes 5, 6, 7 - in the embodiment shown, therefore, only of horizontal slats 3.

Die in Fig. 1 nach oben und in Fig. 2 nach unten weisende Vorder- bzw. Raumseite der Röhrenspanplatte 1 ist mit parallel zueinander und parallel zu den Röhren 5, 6, 7 verlaufenden Schlitzen 10 versehen, wobei jeder zweiten Röhre ein Schlitz zugeordnet ist. Diese Längsschlitze 10 durchbrechen das raumseitige Furnier 8 und sind so bemessen und angeordnet, daß sie bis in eine darunter verlaufende Röhre 6, 7 reichen, so daß bei der in den Fig. 1 und 2 dargestellten Röhrenspanplatte 1 jede zweite Röhre, nämlich die Röhren 6, 7, raumseitig offen ist.The front or space side of the chipboard 1 pointing upwards in FIG. 1 and downwards in FIG. 2 is provided with slots 10 which run parallel to one another and parallel to the tubes 5, 6, 7, a slot being assigned to every second tube . These longitudinal slots 10 break through the veneer 8 on the room side and are dimensioned and arranged such that they extend into a tube 6, 7 running underneath, so that in the tube chipboard 1 shown in FIGS. 1 and 2 every other tube, namely the tubes 6 , 7, is open on the room side.

Die in Fig. 1 nach unten und in Fig. 2 nach oben weisende Rückseite der Röhrenspanplatte 1 ist mit parallel zueinander und rechtwinklig zu den Röhren 5, 6, 7 verlaufenden, vom rückwärtigen Furnier 9 abgedeckten schlitzförmig.ausgebildeten Ausnehmung 11 versehen, die sich über die gesamte Breite der Platte erstrecken. Diese Querschlitze 11 sind so bemessen, daß sie nach außen durch das Furnier 9 abgedeckte Verbindungskanäle zwischen den parallel zueinander verlaufenden Röhren 5, 6, 7 bilden.The downward in FIG. 1 and upward in FIG. 2 of the chipboard 1 is parallel to one another and provided at right angles to the tubes 5, 6, 7 and formed from the rear veneer 9 slot-shaped recess 11, which extend over the entire width of the plate. These transverse slots 11 are dimensioned such that they form connecting channels, which are covered by the veneer 9, between the tubes 5, 6, 7 running parallel to one another.

Die in Fig. 3 dargestellte Röhrenspanplatte 1 entspricht in ihrem Aufbau grundsätzlich der in den Fig. 1 und 2 dargestellten Röhrenspanplatte 1. Bei ihr ist jedoch jede zweite ihrer raumseitig über einen Schlitz 10 offenen Röhren, nämlich die Röhren 7, auch an der Rückseite offen und zwar über Schlitze 12, die durch das rückwärtige Furnier 9 hindurchgehen und bis in die darunter verlaufenden Röhren 7 reichen. Jeder dieser Röhren 7 sind dabei mehrere solcher Schlitze 12 zugeordnet, die gegeneinander axial und zu dem zugeordneten raumseitigen Längsschlitz 10 fluchtend ausgerichtet sind. Grundsätzlich wäre es jedoch auch möglich, die Querausnehmungen 11 teilweise unabgedeckt zu lassen.The structure of the chipboard 1 shown in FIG. 3 corresponds fundamentally to that of the chipboard 1 shown in FIGS. 1 and 2. However, every other one of its tubes that are open on the room side via a slot 10, namely the tubes 7, is also open at the rear namely through slots 12 which pass through the rear veneer 9 and extend into the tubes 7 running underneath. Each of these tubes 7 is assigned a plurality of such slots 12 which are axially aligned with one another and aligned with the associated longitudinal slot 10 on the room side. In principle, however, it would also be possible to leave the transverse recesses 11 partially uncovered.

Die dargestellten Röhrenspanplatten 1 können mit Vorteil als schallschluckende Wand- oder Deckenverkleidungen eingesetzt werden, vorzugsweise unter Zwischenschaltung eines Lattenrostes, wobei der Zwischenraum zwischen der Plattenrückseite und der Wand bzw. der Decke vorzugsweise mit Mineralwolle o.dgl. Isoliermaterial ausgefüllt wird.The chipboard panels 1 shown can advantageously be used as sound-absorbing wall or ceiling cladding, preferably with the interposition of a slatted frame, the space between the back of the panel and the wall or ceiling preferably with mineral wool or the like. Insulating material is filled.

Wird die erfindungsgemäße Röhrenspanplatte nicht direkt, sondern unter Zwischenlage eines vorzugsweise hauptsächlich aus Querlatten bestehenden Lattenrostes an einer Wand montiert, so bringt dies den zusätzlichen Vorteil, daß etwaige Wandunebenheiten ausgeglichen werden können. Durch die die Plattenröhren miteinander verbindenden und nach ihrer Herstellung durch die Furnierlage 9 abgedeckten Ausnehmungen 11 wird die Schallabsorption ohne besonderen Mehraufwand wesentlich verbessert. Von Bedeutung ist hierbei, daß die Ausnehmungen 11, wie eingangs bereits erwähnt, beliebig gestaltet und bemessen sein können, da sie nicht von einer der Schmalseiten der Spanplatte 1 her, sondern von hinten, vor ihrer Abdeckung durch die Furnierlage 9 ausgearbeitet werden können. Es ist deshalb auch möglich, den Durchgangsquerschnitt dieser Ausnehmungen beliebig zu verändern, was sich günstig auf die Absorption von Schallwellen auswirken kann.If the tubular chipboard according to the invention is not mounted directly on a wall, but rather with the interposition of a slatted frame, which preferably consists mainly of transverse slats, this has the additional advantage that any unevenness in the wall can be compensated for. Through the Recesses 11 connecting plate tubes to one another and, after their production, covered by the veneer layer 9, the sound absorption is significantly improved without any particular additional expenditure. It is important here that the recesses 11, as already mentioned at the beginning, can be designed and dimensioned as desired, since they cannot be worked out from one of the narrow sides of the chipboard 1, but from behind, before they are covered by the veneer layer 9. It is therefore also possible to change the passage cross section of these recesses as desired, which can have a favorable effect on the absorption of sound waves.

Durch das Zusammenwirken der auf der Plattenvorderseite vorgesehenen Schlitze 10 und der damit kommunizierenden Röhren werden hohe Schallfrequenzen absorbiert, durch das Zusammenwirken der querverlaufenden Ausnehmungen 11 und der damit kommunizierenden Röhren, mittlere Frequenzen und durch die Mineralwolle, die im Zwischenraum zwischen der Rückwand der Spanplatte und der Wand unterbringbar ist, untere Schallfrequenzen.Due to the interaction of the slots 10 provided on the front of the board and the tubes communicating with them, high sound frequencies are absorbed, due to the interaction of the transverse recesses 11 and the tubes communicating with them, medium frequencies and due to the mineral wool in the space between the rear wall of the particle board and the Wall can be accommodated, lower sound frequencies.
