Definitions
- the invention relates to an endless timber rod, which is composed of individual rods of shorter lengths and each with the same cross section.
- the present invention is therefore based on the object of providing an endless timber rod made of individual rods which has as little as possible in its properties from an endless timber rod made from a single tree trunk differentiates and the production of the waste is limited to a minimum.
- a finger joint is defined as a connection between two solid woods, for example boards, planks or beams, the ends of which engage with one another and are glued together with wedge-shaped tines of the same pitch and the same profile.
- the continuous timber rod according to the invention thus initially has the advantage that the cross-section of the continuous timber rod is uniform over its entire length due to the finger connections of adjacent individual rods and the timber rod according to the invention does not differ from one made from a single tree trunk.
- an endless timber rod of any length can be made by means of logs with the same cross-sectional area.
- a single bar can be formed mechanically with the finger prongs and, if necessary, can be connected to another single bar in the subsequent work step.
- the endless timber rod according to the invention can thus also be assembled directly in the sawmill that cuts the individual rods.
- the length of the individual individual rods is particularly preferably approximately the same. This allows the raw wood to be standardized so that the log can be felled, divided to the standard size and thus easily recovered from the forest and transported.
- the sawmill that processes the tree trunks can be summarized much more compactly because only the standardized short trunks have to be sawn, so that the transport routes are shorter and the storage space becomes smaller.
- a particularly preferred continuous timber rod is characterized in that the individual rods are each formed from different tree trunks. This allows the tree trunks to be divided and sorted on site, for example in standardized lengths, and connected in the sawmill to form an endless timber rod. In this way, the waste wood is reduced to a minimum during the manufacture of the continuous timber rod.
- Fig. 1 denotes an endless timber rod, which is composed of four wooden beams 2, 3, 4, 5 of the same cross-section.
- the two end faces 2b, 3a, 3b, 4a, 4b, 5a are each formed with finger prongs of the same pitch and the same profile.
- the interlocking finger joints of adjacent beams 2,3; 3.4; 4,5 are firmly connected by means of an adhesive (not shown).
- the bonding is preferably carried out with a one-component polyurethane adhesive.
- One-component polyurethane adhesives react without hardener in the usual sense, but require water that is present in the wood to be glued.
- the adhesive is chemically cured by combining the adhesive and water, whereby the higher the moisture content, the faster the adhesive sets.
- the wood removed from the forest which has a moisture content of more than 15%, can then be processed immediately after cutting and sawing a tree.
- One-component polyurethane adhesives react with the water in the wood, causing the combination of adhesive and water to chemically harden. Polyurethane adhesives can penetrate through the fibers of the wood due to the pressure created by their foaming in the joint of the two wooden parts to be connected, and thus anchor themselves in the wood. This leads to a stable connection of the parts glued together.
- the lengths l1, l2, l3, l4, the respective beams 2, 3, 4, 5 can be different, but are preferably the same, so that this standard measure enables uniform means of transport and storage areas.
- Fig. 3 it is shown how in a conventional manner a timber rod 10 is worked out from a single tree trunk 11.
- the smallest cross-sectional area d min of the tree trunk 11 determines the cross section d B of the timber rod 10. If a larger cross-sectional area d B of the timber rod 10 is desired, only a shorter length of the tree trunk 11 can be used.
- FIG. 4 shows that because of the continuous timber rod 1 according to the invention, the tree trunk 11 can be divided into, for example, three shorter trunks 11a, 11b, 11c, preferably with a standardized length l, for example four meters.
- These logs 11a, 11b, 11c have different minimum cross-sectional areas d min, a , d min, b , d min, c , so that the beams 12a, 12b, 12c worked out from the individual logs 11a, 11b, 11c also have different cross-sectional areas d B, a , d B, b , d B, c .
- These individual beams 12a, 12b, 12c can then be connected to other beams of the same cross-sectional area via the finger joint K described above to form the continuous timber rod 1 according to the invention, as shown in FIG. 1.

Abstract
Description
Die Erfindung betrifft eine Endlosbauholzstange, die aus Einzelstangen geringerer Längen und jeweils gleichen Querschnitts zusammengesetzt ist.The invention relates to an endless timber rod, which is composed of individual rods of shorter lengths and each with the same cross section.
Derartige Endlosbauholzstangen sind bereits bekannt.Endless timber rods of this type are already known.
So werden bekannte Endlosbauholzstangen beispielsweise aus Einzelstangen dadurch hergestellt, daß zwei benachbarte Einzelstangen über seitlich verlaufende Seitenhölzer durch beispielsweise Schraub- oder sonstige Verbindungen zusammengehalten werden. Diese Verbindungstechnik ist jedoch arbeitsaufwendig und optisch unbefriedigend, da die Verbindungen vorstehen und sichtbar sind.Known continuous timber rods are made, for example, from individual rods in that two adjacent individual rods are held together by laterally extending side members, for example by screwing or other connections. However, this connection technique is labor-intensive and optically unsatisfactory since the connections protrude and are visible.
Um solche Verbindungen möglichst zu vermeiden bzw. deren Anzahl gering zu halten, werden daher möglichst lange Baumstämme, vorzugsweise in der Länge der zu fertigenden Endlosbauholzstangen, benötigt, wobei die geringste Querschnittsfläche des Baumstammes die Querschnittsfläche der zu fertigenden Bauholzstange festlegt. Dies führt dazu, daß große Teile des Stammes zu minderwertigen Produkten verarbeitet werden und außerdem eine Menge Abfall entsteht, was zu Entsorgungsproblemen und erhöhten Umweltbelastungen führt. Außerdem findet die Länge derartiger Bauholzstangen in der Länge der Baumstämme von in der Regel bis zu 12 Meter ihre natürliche Grenze. Wird aber eine Querschnittfläche einer Bauholzstange gewünscht, die größer als die geringste Querschnittfläche eines Baumstammes ist, so läßt sich die gesamte Baumstammlänge nicht nutzen. Dies macht die Verbindung auf die oben beschriebene herkömmliche Weise zweier oder mehrerer Einzelstangen zu einer Endlosbauholzstange mit den oben angeführten Nachteilen erforderlich.In order to avoid such connections as far as possible or to keep their number small, logs as long as possible, preferably in the length of the continuous timber rods to be manufactured, are therefore required, the smallest cross-sectional area of the log determining the cross-sectional area of the timber rod to be manufactured. As a result, large parts of the strain are processed into inferior products and a lot of waste is generated, which leads to disposal problems and increased environmental pollution. In addition, the length of such timber poles is normally limited to the length of the tree trunks of up to 12 meters. However, if a cross-sectional area of a timber rod that is larger than the smallest cross-sectional area of a tree trunk is desired, the entire tree trunk length cannot be used. This requires the connection in the conventional manner described above of two or more individual bars to form an endless timber bar with the disadvantages mentioned above.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Endlosbauholzstange aus Einzelstangen bereitzustellen, die sich in ihren Eigenschaften von einer aus einem einzigen Baumstamm gefertigten Endlosbauholzstange möglichst wenig unterscheidet und bei deren Herstellung der anfallende Abfall auf ein Minimum begrenzt ist.The present invention is therefore based on the object of providing an endless timber rod made of individual rods which has as little as possible in its properties from an endless timber rod made from a single tree trunk differentiates and the production of the waste is limited to a minimum.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß benachbarte Einzelstangen über eine Keilzinkenverbindung miteinander verbunden sind. Eine Keilzinkenverbindung ist als eine Verbindung zweier Vollhölzer, zum Beispiel Bretter, Bohlen oder Balken, definiert, deren Enden mit keilförmigen Zinken gleicher Teilung und gleichen Profils ineinander greifen und miteinander verleimt sind.This object is achieved in that adjacent individual rods are connected to one another via a finger joint. A finger joint is defined as a connection between two solid woods, for example boards, planks or beams, the ends of which engage with one another and are glued together with wedge-shaped tines of the same pitch and the same profile.
Die erfindungsgemäße Endlosbauholzstange hat damit zunächst den Vorteil, daß durch die Keilzinkenverbindungen benachbarter Einzelstangen der Querschnitt der Endlosbauholzstange über deren gesamte Länge einheitlich ist und sich die erfindungsgemäße Bauholzstange dadurch nicht von einer aus einem einzigen Baumstamm gefertigten unterscheidet. Mit der erfindungsgemäßen Bauholzstange läßt sich mittels beliebig abgelängter Stämme mit gleicher Querschnittsfläche eine Endlosbauholzstange beliebiger Länge anfertigen. Eine Einzelstange kann maschinell mit den Keilzinken ausgebildet und gegebenenfalls schon im nachfolgenden Arbeitsschritt mit einer anderen Einzelstange verbunden werden. Die erfindungsgemäße Endlosbauholzstange kann somit direkt in dem Sägewerk, das die Einzelstangen zusägt, auch zusammengesetzt werden. Das bisher meist an anderer Stelle erfolgende arbeitsintensive Ausbilden herkömmlicher Verbindungen ist dann nicht mehr erforderlich, wodurch die Herstellungskosten der erfindungsgemäßen Endlosbauholzstange reduziert werden können. Außerdem kann die Lagerhaltung vereinfacht werden, da nunmehr keine unzerteilten Baumstämme mit Längen von beispielsweise bis zu 12 Metern zu lagern sind.The continuous timber rod according to the invention thus initially has the advantage that the cross-section of the continuous timber rod is uniform over its entire length due to the finger connections of adjacent individual rods and the timber rod according to the invention does not differ from one made from a single tree trunk. With the timber rod according to the invention, an endless timber rod of any length can be made by means of logs with the same cross-sectional area. A single bar can be formed mechanically with the finger prongs and, if necessary, can be connected to another single bar in the subsequent work step. The endless timber rod according to the invention can thus also be assembled directly in the sawmill that cuts the individual rods. The labor-intensive formation of conventional connections, which has so far mostly been carried out elsewhere, is then no longer necessary, as a result of which the production costs of the continuous timber rod according to the invention can be reduced. In addition, warehousing can be simplified since no undivided tree trunks with lengths of, for example, up to 12 meters are now to be stored.
Werden die Keilzinken mittels eines Einkomponenten-Polyurethan-Klebstoffes verbunden, so hat dies weiterhin den großen Vorteil, daß das aus dem Wald abtransportierte Holz, welches Feuchtigkeiten von über 15 % aufweist, sofort nach dem Sägen weiterverarbeitet werden kann, wodurch die Kosten für die Trocknung und für die Zwischenlagerung entfallen. Einkomponenten-Polyurethan-Klebstoffe reagieren ohne Härter im üblichen Sinne, sondern benötigen Wasser, das in der Umgebungsluft und im zu verklebenden Material, also im Holz, vorhanden ist. Durch die Verbindung von Klebstoff und Wasser wird der Klebstoff chemisch ausgehärtet, wobei der Klebstoff umso schneller abbindet, je höher der Feuchtigkeitsgehalt ist.If the finger joints are connected using a one-component polyurethane adhesive, this has the further advantage that the wood removed from the forest, which has a moisture content of more than 15%, can be processed immediately after sawing, thereby reducing the cost of drying and are no longer required for intermediate storage. One-component polyurethane adhesives react without hardener in the usual sense, but require water that is present in the ambient air and in the material to be bonded, i.e. in the wood. The adhesive is chemically cured by combining the adhesive and water, whereby the higher the moisture content, the faster the adhesive sets.
Besonders bevorzugt ist die Lange der einzelnen Einzelstangen etwa gleich. Dies erlaubt eine Standardisierung des Rohholzes, so daß der Stamm gefällt, auf das Standardmaß geteilt und somit einfacher aus dem Wald geborgen und transportiert werden kann. Das die Baumstämme verarbeitende Sägewerk kann wesentlich kompakter zusammengefaßt werden, weil nur die standardisierten kurzen Stämme zu sägen sind, so daß die Transportwege kürzer und die Lagerflächen kleiner werden.The length of the individual individual rods is particularly preferably approximately the same. This allows the raw wood to be standardized so that the log can be felled, divided to the standard size and thus easily recovered from the forest and transported. The sawmill that processes the tree trunks can be summarized much more compactly because only the standardized short trunks have to be sawn, so that the transport routes are shorter and the storage space becomes smaller.
Eine besonders bevorzugte Endlosbauholzstange kennzeichnet sich dadurch, daß die Einzelstangen jeweils aus verschiedenen Baumstämmen ausgebildet sind. Dies erlaubt, die Baumstämme vor Ort, beispielsweise in standardisierte Längen, zu teilen sowie zu sortieren und im Sägewerk zu einer Endlosbauholzstange zu verbinden. Auf diese Weise wird der Holzabfall bei der Herstellung der Endlosbauholzstange auf ein Minimum reduziert.A particularly preferred continuous timber rod is characterized in that the individual rods are each formed from different tree trunks. This allows the tree trunks to be divided and sorted on site, for example in standardized lengths, and connected in the sawmill to form an endless timber rod. In this way, the waste wood is reduced to a minimum during the manufacture of the continuous timber rod.
Weitere Vorteile ergeben sich aus der Beschreibung und der beigefügten Zeichnung. Ebenso können die vorstehend genannten und die noch weiter aufgeführten Merkmale erfindungsgemäß jeweils einzeln für sich oder in beliebiger Kombination miteinander verwendet werden. Die erwähnte Ausführungsform ist nicht als abschließende Aufzählung zu verstehen, sondern hat vielmehr beispielhaften Charakter.Further advantages result from the description and the attached drawing. Likewise, the features mentioned above and those listed further can be used according to the invention individually or in any combination with one another. The embodiment mentioned is not to be understood as an exhaustive list, but rather has an exemplary character.

In Fig. 1 ist mit 1 eine Endlosbauholzstange bezeichnet, die sich aus vier Holzbalken 2, 3, 4, 5 gleichen Querschnitts zusammensetzt. Wie Fig. 2 zeigt, sind jeweils die beiden Stirnseiten 2b, 3a, 3b, 4a, 4b, 5a mit Keilzinken gleicher Teilung und gleichen Profils ausgebildet. Zur Ausbildung einer Endlosbauholzstange 1 werden zwei benachbarte Holzbalken 2,3; 3,4; 4,5 so weit zusammengeschoben, bis die Teilzinken benachbarter Balken 2b, 3a; 3b, 4a; 4b, 5a ineinandergreifen. Die ineinandergreifenden Keilzinken benachbarter Balken 2,3; 3,4; 4,5 werden mittels eines Klebstoffes (nicht gezeigt) fest verbunden. Vorzugsweise erfolgt diese Klebeverbindung K zweier benachbarter Balken 2,3; 3,4; 4,5 unter einem gewissen Preßdruck.In Fig. 1, 1 denotes an endless timber rod, which is composed of four
Um die Herstellung derartiger Keilzinkenverbindungen K schon im Sägewerk völlig ohne bzw. mit einer stark reduzierten technischen Holztrocknung zu ermöglichen, erfolgt die Verklebung vorzugsweise mit einem Einkomponenten-PolyurethanKlebstoff. Einkomponenten-Polyurethan-Klebstoffe reagieren ohne Härter im üblichen Sinne, sondern benötigen Wasser, das in dem zu verklebenden Holz, vorhanden ist. Durch die Verbindung von Klebstoff und Wasser wird der Klebstoff chemisch ausgehärtet, wobei der Klebstoff umso schneller abbindet, je höher der Feuchtigkeitsgehalt ist. Das aus dem Wald abtransportierte Holz, welches einen Feuchtigkeitsgehalt von über 15 % aufweist, kann dann sofort nach dem Fällen und Sägen eines Baumes weiterverarbeitet werden. EinkomponentenPolyurethan-Klebstoffe reagieren mit dem im Holz vorhandenen Wasser, wodurch die Verbindung von Klebstoff und Wasser chemisch aushärtet. Polyurethan-Klebstoffe können durch den Druck, der durch ihr Aufschäumen in der Fuge der beiden zu verbindenden Holzteile entsteht, durch die Fasern des Holzes dringen und sich dadurch im Holz verankern. Dies führt zu einer stabilen Verbindung der miteinander verklebten Teile.In order to enable the production of finger joints K of this type in the sawmill completely without or with a greatly reduced amount of technical wood drying, the bonding is preferably carried out with a one-component polyurethane adhesive. One-component polyurethane adhesives react without hardener in the usual sense, but require water that is present in the wood to be glued. The adhesive is chemically cured by combining the adhesive and water, whereby the higher the moisture content, the faster the adhesive sets. The wood removed from the forest, which has a moisture content of more than 15%, can then be processed immediately after cutting and sawing a tree. One-component polyurethane adhesives react with the water in the wood, causing the combination of adhesive and water to chemically harden. Polyurethane adhesives can penetrate through the fibers of the wood due to the pressure created by their foaming in the joint of the two wooden parts to be connected, and thus anchor themselves in the wood. This leads to a stable connection of the parts glued together.
Die Längen l₁, l₂, l₃, l₄, der jeweiligen Balken 2, 3, 4, 5 können unterschiedlich sein, sind aber vorzugsweise gleich, damit dieses Standardmaß einheitliche Transportmittel und Lagerflächen ermöglicht.The lengths l₁, l₂, l₃, l₄, the
In Fig. 3 ist gezeigt, wie in herkömmlicher Weise eine Bauholzstange 10 aus einem einzigen Baumstamm 11 herausgearbeitet ist. Die geringste Querschnittsfläche dmin des Baumstammes 11 bestimmt dabei den Querschnitt dB der Bauholzstange 10. Wird eine größere Querschnittsfläche dB der Bauholzstange 10 gewünscht, so kann nur eine geringere Länge des Baumstammes 11 genutzt werden.In Fig. 3 it is shown how in a conventional manner a
Fig. 4 dagegen zeigt, daß aufgrund der erfindungsgemäßen Endlosbauholzstange 1 der Baumstamm 11 in beispielsweise drei kürzere Stämme 11a, 11b, 11c mit vorzugsweise einer standardisierten Länge l, z.B. vier Meter, zerteilt werden kann. Diese Stämme 11a, 11b, 11c weisen unterschiedliche geringste Querschnittsflächen dmin,a, dmin,b, dmin,c auf, so daß auch die aus den einzelnen Stämmen 11a, 11b, 11c herausgearbeiten Balken 12a, 12b, 12c unterschiedliche Querschnittsflächen dB,a, dB,b, dB,c aufweisen. Diese einzelnen Balken 12a, 12b, 12c können dann mit anderen Balken gleicher Querschnittsfläche über die oben beschriebene Keilzinkenverbindung K zu der erfindungsgemäßen Endlosbauholzstange 1 verbunden werden, wie in Fig. 1 gezeigt ist.FIG. 4, on the other hand, shows that because of the
Der Vergleich mit Fig. 3 zeigt, daß durch die Zerteilung von Baumstämmen bei der Herstellung der für die Erfindung erforderlichen Einzelstangen das anfallende überschüssige Holz auf ein Minimum reduziert werden kann.The comparison with Fig. 3 shows that by cutting tree trunks in the manufacture of the individual rods required for the invention, the excess wood can be reduced to a minimum.
