Definitions
- the invention relates to a method for producing end products, in particular wall elements, cross-laminated timber parts, moldings and the like, from wood, wood-based materials, plastic and the like according to the preamble of claim 1.
- a method for producing end products in particular wall elements, cross-laminated timber parts, moldings and the like, from wood, wood-based materials, plastic and the like according to the preamble of claim 1.
- Such a method is disclosed in the document US6058991 A1 known.
- Solid wood wall elements made of cross-laminated timber consist of several layers.
- the boards in the middle layers are laid loosely together and connected to one another via the layers, which are advantageously cross layers.
- the top layers are mostly glued.
- wall elements made of cross laminated timber consist of an odd number of layers, for example 5, 7 or 9 layers, the boards of adjacent layers being arranged perpendicular to one another in their longitudinal orientation.
- the production of wall elements to place elongated components, such as boards, in a first layer and on the back this layer in the butt region of the components of the first layer overlapping and connecting smaller components together. There is a distance between adjacent narrower components, as a result of which cavities or depressions are formed in the wall element.
- the so-called middle layer or if the wall elements are provided with cover layers anyway, the boards of the first layer can also have a spacing and can be connected in an overlapping manner to the boards of the second layer arranged on a gap.
- the object of the invention is to develop the generic method in such a way that the end products can be produced in a cost-effective manner.
- an output part is used which is separated into at least two components in such a way that these components have different thicknesses over their width.
- the output part is thus intelligently separated so that the end product is created or formed from the components created by the separation process.
- the components created after the separation process can already be the end product in the form of strips. However, it is also possible to subsequently assemble the components created after the separation process to form the end product, for example a wall element.
- the starting part is separated by a cutting process, preferably with the aid of a broaching tool or by a sawing process.
- the components each having different thicknesses can be placed next to one another in such a way that the thinner area of one component adjoins the thicker area of the adjacent component.
- depressions are formed between the thick areas of adjacent components due to the thinner areas located there. They extend over the length of the components.
- the transition from the thicker to the thinner area of the components can take place via one step.
- the starting part is produced from basic elements.
- these basic elements have an angular cross section and lie flat against one another with their outer sides.
- the two basic elements are firmly connected to one another in a suitable manner, advantageously glued to one another.
- the basic elements which are firmly connected to one another form a block-shaped output part, which, however, is not formed in one piece.
- Such an output part can in the same How a one-piece output part can be separated into at least two components.
- the output part is separated into a plurality of components, a separating cut advantageously being carried out between the next but one component which cuts through the output part.
- At least one depression is made in each case in the outside of each base element before being assembled into the starting part. If the basic elements are then assembled to form the initial part, the depressions in the basic elements form a cavity in the initial part.
- the cuts are made from the mutually opposite outer sides of the starting part up into this cavity.
- the two components are also created, which have different thicknesses over their width.
- the components resulting from the separation of the starting part can advantageously be assembled with their ends forming the long sides to form plate-shaped elements. They are then placed on top of each other to form a wall element.
- a single plate-shaped element is sufficient to form a wall element. It has a flat outer side on one side, while on the rear side it has depressions or cavities which are formed by the respectively thinner regions of the components.
- At least two plate-shaped elements can also be placed on one another.
- adjacent, plate-shaped elements which are seated one on top of the other are arranged rotated relative to one another.
- the plate-shaped elements By placing the plate-shaped elements on top of each other there are cavities, which enforce the wall element. If the plate-shaped elements which are seated one on top of the other are rotated relative to one another, then the cavities in the different layers lie correspondingly at an angle to one another.
- the adjacent components can interlock like a tongue and groove, resulting in a high stability and strength of the plate-shaped elements.
- the cavities or depressions extend over the length of the component.
- solid components are obtained through a separation technique, which can be used as strips or can be assembled, for example, into wall elements or cross-laminated timber.
- the wall elements then contain air spaces which are advantageous in terms of heat and air conditioning. This results in a larger total volume than the original parts themselves, and thus material and cost savings.
- Fig. 1 shows that a groove 26 can be made in the end face 25 of the component 13 adjacent to the outside 6, which extends over the length of the component 13.
- the opposite end face 27 of the thinner part 17 of the component 13 is provided with a tongue 28 corresponding to the groove 26.
- Fig. 1 is indicated by dashed lines, the two when opening the output part 41 ( 6 to 8 ) resulting components 13, 14 are placed so that the spring 28 of the one component 13 engages in the groove 26 of the component 14. In this way, the components 13, 14 can be placed one behind the other and firmly connected to one another. In this way, a plate-shaped element 29 is created which has a flat outer side 6, 7 and is provided with cavities 30 on its opposite side.
- the components 13, 14 on the end face 25 of the thicker area 15 have an end fold 31 open to the outside 6, 7, the height of which perpendicular to the outside 6 corresponds to the height of the opposite end face 27 of the thinner area 17 of the component 13.
- the components 13, 14 are in turn placed one behind the other, the thinner area 17 of the component 13 engaging in the corresponding fold 32 of the thicker part 16 of the component 14.
- Both components 13, 14 are firmly connected, for example glued.
- a plate-shaped element 33 results, which has the flat outside 6, 7 and the cavities 30 on the opposite outside.
- the outer sides 19, 22 of the components 13, 14 which have the cavities 30 likewise lie in a common plane.
- Fig. 3 shows the possibility to form the form-locking means for connecting adjacent components in cross section, for example triangular.
- the end face 25 of the wider area 15 of the component 13 is provided with the groove 26 which is triangular in cross section and the opposite end face 27 of the thinner area 17 is provided with the triangular spring 28.
- adjacent components 13, 14 can be firmly connected to one another to form the plate-shaped elements.
- the corresponding profiling can be carried out entirely or partially before the cutting in a continuous process together with the pre-planing, sawing and cutting. If the components have to be planed anyway, it is advisable to carry out the final profiling in this process step.
- the 4 and 5 show by way of example how the plate-shaped elements 29 formed from the components 13, 14 put together can be layered, for example, to form a wall element 34 or a cross-laminated timber part.
- the wall element 34 is formed by five plate-shaped elements 29.
- the wall element can also be formed from a smaller or a larger number of plate-shaped elements.
- the plate-shaped elements 29 are alternately placed on top of one another in such a way that the components or boards and cavities 30 of adjacent elements 29 run at right angles to one another.
- the wall element 34 thus has entry openings into the cavities 30 at all edges.
- One outside 6/7 of the wall element 34 is flat and closed. If the opposite outer side is also to be flat and closed, the outer element 29 can be applied in mirror image, so that the cavities of the last two elements 29 lie opposite one another.
- a cover layer can also be applied to the outer element 29. It can be made of a different material than the elements 29, for example plasterboard, chipboard or the like.
- intermediate layers can be provided between some or all of the elements, which are made of other materials and serve, for example, as insulation or soundproofing layers.
- Fig. 6 shows a basic element 35, which has a rectangular cross section, for example a board or planks.
- grooves 37 are advantageously made at equal intervals, which extend over the length of the base element 35.
- the outer side 36 is adjoined by longitudinal sides 38, 39 which run at right angles to them and parallel to one another, and this in turn is joined by a flat outer side 40 which runs parallel to the outer side 36.
- the grooves 37 are milled into the outside 36.
- Two such basic elements 35 are connected to one another with their outer sides 36 and, on their opposite outer sides, each with a further basic element 35 ′, which advantageously has the same rectangular cross section but is not milled, to form the output part 41, for example by gluing.
- the grooves 37 form rectangular cavities 42 in cross section, which are half the width of the output part 41 and extend over the length of the output part 41.
- the output part 41 is divided by saw cuts 4, 5 and 43 into the components 13, 14.
- the saw cuts 4, 5 are guided perpendicularly to the outside into the cavities 42 from the two outer sides 40 of the output part 41. In this way, the components 13, 14 are formed.
- the saw cut 43 is guided in the middle between adjacent cavities 42 perpendicular to the outer sides 40 and cuts through the output part 41. This results in not only two, but several, in the exemplary embodiment eight identical components.
- the components 13, 14 created in this way can, as shown in FIG 1 to 3 has been described, can be assembled into the plate-shaped elements.
- the components 13, 14 can also have a shape corresponding to 1 to 3 to have.
- the grooves and tongues can already be milled in the initial part 41. However, it is also possible to attach the grooves and tongues to the components 13, 14 only after dividing the output part 41.
- an inclined cut 44 is made in the base element 35 from the outside 36 and extends approximately to half the thickness of the base element 35. Subsequently, two such basic elements 35 are firmly connected to one another with their outer sides 36 lying against one another to form the output part 41, for example glued together.
- the two saw cuts 44 form in the output part 41 a narrow cavity 45 which extends in the oblique direction and extends beyond the joining plane 46 between the two basic elements 35. This joining plane 46 runs in Fig. 10 horizontal.
- the joining plane 46 runs vertically. It is also penetrated by the cavity 45.
- the cavity 45 is located centrally in the output part 41 and obliquely to its longitudinal plane.
- the cavity 45 extends over the entire length of the output part 41.
- the components 13, 14 ( Fig. 12 ) saw cuts 4, 5 are made from the outer sides 38, 39 of the output part 41 and extend to the ends of the cavity 45. Because of the inclined position of the cavity 45, the components 13, 14 have the thicker and the thinner regions 15, 16; 17, 18 and an intermediate area in which the thickness increases continuously from the thinner to the thicker area.
- Fig. 13 shows the possibility that the components 13, 14 are provided with an end profile 47, which in Fig. 13 exemplified by a dashed line is specified.
- the components thus end-profiled can be finished strips or can be assembled into the plate-shaped elements in the manner described.
- the end profile 47 to be manufactured can be in the area of the thinner and the thicker areas 15, 17; 16, 18 of the components 13, 14 have different thicknesses.
- the thinner and the thicker areas are formed obliquely.
- the cuts 4, 5 are thus introduced obliquely. This creates symmetrical end profiles 47 again. Material of this type is saved even further.
- Two or more identical components are preferably produced, since the output part has a symmetrical (point-symmetrical) structure and also the processing, such as the introduction of the saw cuts, is carried out symmetrically.
- two non-identical components for producing the end products can also be obtained from an initial part, in that the initial part and / or processing are not symmetrical.
- bevel cuts can be made in the output part 41 starting from both outer sides 6, 7, which are offset from one another by approximately the cutting width are and merge into each other in half the thickness of the output part, so that the output part is separated directly in one pass. Due to the oblique cuts, the resulting components each have an oblique end face on one side. As a result, the components in connection with pre-profiling have correspondingly form-fitting elements Fig. 3 in the form of triangular projections and grooves which interlock when the components are assembled to form the plate-shaped elements. The oblique cuts create triangular cavities.
- the components 13, 14 formed from the output part 41 can be assembled into plate-shaped elements of different lengths and / or widths.
- the plate-shaped elements in turn can be layered into a wide variety of components, as described, for example, using a wall element 34.
- the cavities 42 can be used for a wide variety of purposes, for example as a climate buffer and Thermal insulation, fire retardant and sound absorbing, or as channels for the passage of cables and the like.
- the method described is also ideally suited for multi-layer board plywood elements.
- the output parts 41 can easily be separated into the components from which the elements 29, 33 are manufactured.
- the components 13, 14 can also be used as raw parts for the production of strips or can be pre-profiled before the separation so that they already form the strip-shaped end product.

Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Endprodukten, insbesondere von Wandelementen, Brettsperrholzteilen, Leisten und dergleichen, aus Holz, Holzwerkstoffen, Kunststoff und dergleichen nach dem Oberbegriff des Anspruchs 1. Ein solches Verfahren wird aus dem Dokument
Es sind Massivholz-Wandelemente aus Brettsperrholz bekannt, die aus mehreren Schichten bestehen. Die Bretter in den Mittellagen werden lose aneinander gelegt und über die Lagen, die vorteilhaft Kreuzlagen sind, miteinander verbunden. Die Decklagen sind meistens verleimt.Solid wood wall elements made of cross-laminated timber are known, which consist of several layers. The boards in the middle layers are laid loosely together and connected to one another via the layers, which are advantageously cross layers. The top layers are mostly glued.
Es ist auch bekannt, Rohbretter vorzuprofilieren, um Gewicht zu sparen.It is also known to pre-profile raw boards to save weight.
Diese Rohbretter werden so vorprofiliert, dass aus diesen vorprofilierten Brettern gebildete Wandelemente wärmetechnisch vorteilhafte Hohlräume enthalten. Allerdings ist eine solche Verfahrensweise aufwändig. Zudem tritt eine erhebliche Menge an Holzabfall auf.These raw boards are pre-profiled so that wall elements formed from these pre-profiled boards contain thermally advantageous cavities. However, such a procedure is complex. There is also a significant amount of wood waste.
In der Regel bestehen Wandelemente aus Brettsperrholz je nach Dicke der Wand, für die sie eingesetzt werden sollen, aus einer ungeraden Anzahl von Schichten, beispielsweise 5, 7 oder 9 Schichten, wobei die Bretter benachbarter Schichten in ihrer Längsorientierung senkrecht zueinander angeordnet sind.As a rule, wall elements made of cross laminated timber, depending on the thickness of the wall for which they are to be used, consist of an odd number of layers, for example 5, 7 or 9 layers, the boards of adjacent layers being arranged perpendicular to one another in their longitudinal orientation.
Es ist auch bekannt, zur Herstellung von Wandelementen längliche Bauteile, wie Bretter, in einer ersten Schicht aneinander zu legen und auf der Rückseite dieser Schicht im Stossbereich der Bauteile der ersten Schicht schmalere Bauteile überlappend aufzusetzen und miteinander zu verbinden. Zwischen benachbarten schmaleren Bauteilen besteht ein Abstand, wodurch Hohlräume bzw. Vertiefungen im Wandelement gebildet werden. Insbesondere im Inneren der Wandelemente, der so genannten Mittelschicht, oder wenn die Wandelemente ohnehin noch mit Deckschichten versehen werden, können die Bretter der ersten Schicht auch einen Abstand aufweisen und überlappend mit den auf Lücke angeordneten Brettern der zweiten Schicht verbunden werden.It is also known for the production of wall elements to place elongated components, such as boards, in a first layer and on the back this layer in the butt region of the components of the first layer overlapping and connecting smaller components together. There is a distance between adjacent narrower components, as a result of which cavities or depressions are formed in the wall element. In particular in the interior of the wall elements, the so-called middle layer, or if the wall elements are provided with cover layers anyway, the boards of the first layer can also have a spacing and can be connected in an overlapping manner to the boards of the second layer arranged on a gap.
Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren so auszubilden, dass die Endprodukte in kostengünstiger Weise hergestellt werden können.The object of the invention is to develop the generic method in such a way that the end products can be produced in a cost-effective manner.
Diese Aufgabe wird beim gattungsgemäßen Verfahren erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic method according to the invention with the characterizing features of claim 1.
Beim erfindungsgemäßen Verfahren wird ein Ausgangsteil verwendet, das in wenigstens zwei Bauteile so aufgetrennt wird, dass diese Bauteile über ihre Breite unterschiedlich dick sind. Das Ausgangsteil wird somit intelligent so aufgetrennt, dass aus den durch den Trennvorgang entstehenden Bauteilen das Endprodukt entsteht bzw. gebildet wird. Die nach dem Trennvorgang entstehenden Bauteile können bereits das Endprodukt in Form von Leisten sein. Es ist aber auch möglich, die nach dem Trennvorgang entstehenden Bauteile anschließend zum Endprodukt, beispielsweise einem Wandelement, zusammenzusetzen.In the method according to the invention, an output part is used which is separated into at least two components in such a way that these components have different thicknesses over their width. The output part is thus intelligently separated so that the end product is created or formed from the components created by the separation process. The components created after the separation process can already be the end product in the form of strips. However, it is also possible to subsequently assemble the components created after the separation process to form the end product, for example a wall element.
Erfindungsgemäß wird das Ausgangsteil durch einen spanenden Trennvorgang, vorzugsweise mit Hilfe eines Räumwerkzeuges oder durch einen Sägevorgang, aufgetrennt.According to the invention, the starting part is separated by a cutting process, preferably with the aid of a broaching tool or by a sawing process.
Die jeweils unterschiedliche Dicke aufweisenden Bauteile können bei einer vorteilhaften Ausführungsform so aneinander gesetzt werden, dass der dünnere Bereich des einen Bauteils an den dickeren Bereich des benachbarten Bauteils anschließt. Dadurch werden zwischen den dicken Bereichen benachbarter Bauteile aufgrund der dort befindlichen dünneren Bereiche Vertiefungen gebildet. Sie erstrecken sich über die Länge der Bauteile.In an advantageous embodiment, the components each having different thicknesses can be placed next to one another in such a way that the thinner area of one component adjoins the thicker area of the adjacent component. As a result, depressions are formed between the thick areas of adjacent components due to the thinner areas located there. They extend over the length of the components.
Der Übergang vom dickeren in den dünneren Bereich der Bauteile kann über eine Stufe erfolgen.The transition from the thicker to the thinner area of the components can take place via one step.
Es ist aber auch möglich, diesen Übergang stufenlos zu gestalten.But it is also possible to make this transition stepless.
Erfindungsgemäß wird das Ausgangsteil aus Grundelementen hergestellt. Diese Grundelemente haben erfindungsgemäß eckigen Querschnitt und liegen mit ihren Außenseiten flächig aneinander. Die beiden Grundelemente sind in geeigneter Weise fest miteinander verbunden, vorteilhaft miteinander verklebt. Die fest miteinander verbundenen Grundelemente bilden ein blockförmiges Ausgangsteil, das jedoch nicht einstückig ausgebildet ist. Ein solches Ausgangsteil kann in gleicher Weise wie ein einstückiges Ausgangsteil in wenigstens zwei Bauteile aufgetrennt werden.According to the invention, the starting part is produced from basic elements. According to the invention, these basic elements have an angular cross section and lie flat against one another with their outer sides. The two basic elements are firmly connected to one another in a suitable manner, advantageously glued to one another. The basic elements which are firmly connected to one another form a block-shaped output part, which, however, is not formed in one piece. Such an output part can in the same How a one-piece output part can be separated into at least two components.
Erfindungsgemäß wird, das Ausgangsteil in mehrere Bauteile aufgetrennt wobei vorteilhaft zwischen jeweils übernächsten Bauteilen ein Trennschnitt ausgeführt wird, der das Ausgangsteil durchtrennt.According to the invention, the output part is separated into a plurality of components, a separating cut advantageously being carried out between the next but one component which cuts through the output part.
Erfindungsgemäß wird in die Außenseite jedes Grundelementes vor dem Zusammensetzen zum Ausgangsteil jeweils wenigstens eine Vertiefung eingebracht. Werden die Grundelemente anschließend zum Ausgangsteil zusammengesetzt, bilden die Vertiefungen in den Grundelementen einen Hohlraum im Ausgangsteil.According to the invention, at least one depression is made in each case in the outside of each base element before being assembled into the starting part. If the basic elements are then assembled to form the initial part, the depressions in the basic elements form a cavity in the initial part.
Erfindungsgemäß werden die Schnitte von den einander gegenüberliegenden Außenseiten des Ausgangsteiles aus bis in diesen Hohlraum geführt. Auf diese Weise entstehen ebenfalls die beiden Bauteile, die über ihre Breite unterschiedliche Dicke haben.According to the invention, the cuts are made from the mutually opposite outer sides of the starting part up into this cavity. In this way, the two components are also created, which have different thicknesses over their width.
Die durch das Auftrennen des Ausgangsteiles entstehenden Bauteile können vorteilhaft mit ihren die Längsseiten bildenden Enden zu plattenförmigen Elementen zusammengesetzt werden. Sie werden anschließend zur Bildung eines Wandelementes aufeinander gesetzt. Grundsätzlich reicht zur Bildung eines Wandelementes ein einziges plattenförmiges Element aus. Es hat auf einer Seite eine ebene Außenseite, während es an der Rückseite Vertiefungen bzw. Hohlräume aufweist, die durch die jeweils dünneren Bereiche der Bauteile gebildet werden.The components resulting from the separation of the starting part can advantageously be assembled with their ends forming the long sides to form plate-shaped elements. They are then placed on top of each other to form a wall element. Basically, a single plate-shaped element is sufficient to form a wall element. It has a flat outer side on one side, while on the rear side it has depressions or cavities which are formed by the respectively thinner regions of the components.
Zur Herstellung der Wandelemente können aber auch wenigstens zwei plattenförmige Elemente aufeinander gesetzt werden.To produce the wall elements, however, at least two plate-shaped elements can also be placed on one another.
Vorteilhaft ist es hierbei, wenn benachbarte, aufeinander sitzende plattenförmige Elemente jeweils verdreht zueinander angeordnet sind. Durch das Aufeinandersetzen der plattenförmigen Elemente ergeben sich Hohlräume, die das Wandelement durchsetzen. Werden die aufeinander sitzenden plattenförmigen Elemente jeweils zueinander verdreht, dann liegen die Hohlräume in den verschiedenen Schichten entsprechend winklig zueinander. Innerhalb der plattenförmigen Elemente können die benachbarten Bauteile nutfederartig ineinandergreifen, wodurch sich eine hohe Stabilität und Festigkeit der plattenförmigen Elemente ergibt.It is advantageous here if adjacent, plate-shaped elements which are seated one on top of the other are arranged rotated relative to one another. By placing the plate-shaped elements on top of each other there are cavities, which enforce the wall element. If the plate-shaped elements which are seated one on top of the other are rotated relative to one another, then the cavities in the different layers lie correspondingly at an angle to one another. Within the plate-shaped elements, the adjacent components can interlock like a tongue and groove, resulting in a high stability and strength of the plate-shaped elements.
Die Hohlräume bzw. Vertiefungen erstrecken sich erfindungsgemäß über die Länge des Bauteiles.According to the invention, the cavities or depressions extend over the length of the component.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention result from the further claims, the description and the drawings.

Mit dem im Folgenden beschriebenen Verfahren werden durch eine Auftrenntechnik Massivbauteile erhalten, die als Leisten eingesetzt oder beispielsweise zu Wandelementen oder Brettsperrholz zusammengesetzt werden können. Die Wandelemente enthalten dann wärme- und klimatechnisch vorteilhafte Lufträume. Dabei ergibt sich ein größeres Gesamtvolumen, als die Ausgangsteile selbst haben, und damit eine Material- und Kostenersparnis.With the process described in the following, solid components are obtained through a separation technique, which can be used as strips or can be assembled, for example, into wall elements or cross-laminated timber. The wall elements then contain air spaces which are advantageous in terms of heat and air conditioning. This results in a larger total volume than the original parts themselves, and thus material and cost savings.
Wenn von einem Endprodukt die Rede ist, dann schließt dies nicht aus, dass ein solches Produkt nicht noch bearbeitet wird.If there is talk of an end product, this does not mean that such a product is not yet being processed.

Die gegenüberliegende Stirnseite 27 des dünneren Teils 17 des Bauteils 13 ist mit einer der Nut 26 entsprechenden Feder 28 versehen. Wie in
Bei der Ausführungsform gemäß
Die entsprechende Profilierung kann je nach Auftrennverfahren bereits gänzlich oder teilweise vor dem Auftrennen im Durchlaufverfahren zusammen mit dem Vorhobeln, Einsägen und Auftrennen erfolgen. Wenn die Bauteile ohnehin nachgehobelt werden müssen, bietet es sich an, die endgültige Profilierung bei diesem Verfahrensschritt auszuführen.Depending on the cutting process, the corresponding profiling can be carried out entirely or partially before the cutting in a continuous process together with the pre-planing, sawing and cutting. If the components have to be planed anyway, it is advisable to carry out the final profiling in this process step.
Die
Die plattenförmigen Elemente 29 werden abwechselnd so aufeinander gesetzt, dass die Bauelemente bzw. Bretter und Hohlräume 30 benachbarter Elemente 29 rechtwinklig zueinander verlaufen. Das Wandelement 34 weist somit an allen Rändern Eintrittsöffnungen in die Hohlräume 30 auf.The plate-shaped
Die eine Außenseite 6/7 des Wandelementes 34 ist eben und geschlossen. Soll auch die gegenüberliegende Außenseite eben und geschlossen sein, kann das äußere Element 29 spiegelbildlich aufgebracht werden, so dass sich die Hohlräume der letzten beiden Elemente 29 gegenüberliegen. Ebenso kann auf das äußere Element 29 eine Deckschicht aufgebracht werden. Sie kann aus einem anderen Material als die Elemente 29 bestehen, beispielsweise aus Gipskarton, aus einer Spanplatte oder dergleichen.One outside 6/7 of the
Abweichend vom dargestellten Ausführungsbeispiel können zwischen einigen oder allen Elementen 29 Zwischenschichten vorgesehen sein, die aus anderen Materialien bestehen und beispielsweise als Isolier- oder Schallschutzschichten dienen.In contrast to the exemplary embodiment shown, intermediate layers can be provided between some or all of the elements, which are made of other materials and serve, for example, as insulation or soundproofing layers.

Zwei solcher Grundelemente 35 werden mit ihren Außenseiten 36 aneinanderliegend und an ihren gegenüberliegenden Außenseiten jeweils mit einem weiteren Grundelement 35', welches vorteilhaft den gleichen rechteckigen Querschnitt hat, aber nicht eingefräst ist, zum Ausgangsteil 41 miteinander verbunden, beispielsweise durch Verleimen. Die Nuten 37 bilden im Querschnitt rechteckige Hohlräume 42, die in halber Breite des Ausgangsteiles 41 liegen und sich über die Länge des Ausgangsteiles 41 erstrecken.Two such

Das zu fertigende Endprofil 47 kann im Bereich der dünneren und der dickeren Bereiche 15, 17; 16, 18 der Bauteile 13, 14 unterschiedliche Dicken aufweisen. Die dünneren und die dickeren Bereiche sind hierbei schräg ausgeformt. Die Schnitte 4, 5 werden so schräg eingebracht. So entstehen wieder symmetrische Endprofile 47. Bei derartigen Profilen wird noch weiter Material eingespart.The
Diese unterschiedlichen Querschnitte der beiden Bauteile ergeben sich je nach Schnittlage der von der Außenseite eingebrachten Sägeschnitte, der Lage bzw. Ausführung des vorgefertigten Hohlraumes im Ausgangsteil.These different cross sections of the two components result depending on the cutting position of the saw cuts made from the outside, the position or design of the prefabricated cavity in the starting part.
Vorzugsweise werden zwei oder mehrere gleiche Bauteile erzeugt, da das Ausgangsteil symmetrischen (punktsymmetrischen) Aufbau hat und auch die Bearbeitung, wie beispielsweise das Einbringen der Sägeschnitte, symmetrisch erfolgt. In gleicher Verfahrensweise können jedoch auch aus einem Ausgangsteil zwei nicht gleiche Bauteile zur Herstellung der Endprodukte erhalten werden, indem Ausgangsteil und/oder Bearbeitung nicht symmetrisch sind.Two or more identical components are preferably produced, since the output part has a symmetrical (point-symmetrical) structure and also the processing, such as the introduction of the saw cuts, is carried out symmetrically. In the same procedure, however, two non-identical components for producing the end products can also be obtained from an initial part, in that the initial part and / or processing are not symmetrical.
Bei einer anderen (nicht dargestellten) Ausführungsform können in das Ausgangsteil 41 von beiden Außenseiten 6, 7 ausgehend Schrägschnitte eingebracht werden, die um etwa die Schnittbreite versetzt zueinander angeordnet sind und in halber Dicke des Ausgangsteils ineinander übergehen, so dass das Ausgangsteil direkt in einem Durchlauf aufgetrennt wird. Aufgrund der schrägen Schnitte haben die so entstandenen Bauteile jeweils auf einer Seite eine schräg verlaufende Stirnseite. Dadurch haben die Bauteile in Verbindung mit einer Vorprofilierung Formschlusselemente entsprechend
Die aus dem Ausgangsteil 41 gebildeten Bauteile 13, 14 können zu plattenförmigen Elementen unterschiedlicher Länge und/oder Breite zusammengesetzt werden. Die plattenförmigen Elemente ihrerseits können zu unterschiedlichsten Bauteilen geschichtet werden, wie beispielhaft anhand eines Wandelementes 34 beschrieben. Die Hohlräume 42 können für unterschiedlichste Zwecke eingesetzt werden, beispielsweise als Klimapuffer und Wärmeisolation, feuerhemmend und schallabsorbierend, oder als Kanäle zur Durchführung von Kabeln und dergleichen. Das beschriebene Verfahren ist auch für mehrlagige Brett-Sperrholz-Elemente hervorragend geeignet. Die Ausgangsteile 41 lassen sich verfahrenstechnisch einfach in die Bauteile auftrennen, aus denen die Elemente 29, 33 gefertigt werden.The
Durch das Auftrennen des Ausgangsteiles werden Bauteile erzeugt, welche über ihre Breite unterschiedliche Dicke aufweisen. Die Dicke ändert sich dabei über die Breite stufenförmig oder unstetig. Dadurch lässt sich eine enorme Material- und damit Kosteneinsparung erreichen, welche beispielsweise bei der Verwendung für die beschriebenen Wandelemente umso größer ist, je größer der seitliche Versatz der Sägeschnittfugen gewählt werden kann.By separating the starting part, components are produced which have different thicknesses over their width. The thickness changes stepwise or discontinuously across the width. As a result, an enormous saving in material and thus costs can be achieved, which is greater, for example, when the wall elements described are used, the greater the lateral offset of the saw cut joints can be selected.
Die Bauteile 13, 14 können auch als Rohteile zur Herstellung von Leisten eingesetzt werden oder vor dem Auftrennen bereits so vorprofiliert sein, dass sie bereits das leistenförmige Endprodukt bilden.The
