Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines im Außenumriß rechteckigen Holzhohlbalkens in Verbundbauweise, welcher aus mehreren, sich in Längsrichtung des Holzhohlbalkens erstreckenden, miteinander verbundenen, einen Hohlraum umschließenden Einzelelementen zusammengesetzt ist, wobei zur Herstellung der Einzelelemente des zu fertigenden Holzhohlbalkens Zunächst aus konischen Rundholzabschnitten je eine Kernbohle herausgeschnitten wird, wobei eine quaderförmige Kernbohle bei einem kernparallelen Schnitt und eine keilförmige Kernbohle bei einem faserparallelen Schnitt erhalten wird und jedes der beiden hierdurch anfallenden Stammaußensegmente mit drei voneinander getrennten Außenflächen versehen wird und anschließend die getrockneten Stammaußensegmente senkrecht zur Schnittfläche für die Kernbohle getrennt werden, wobei die die Außensegmente teilende Schnittfläche so gelegt wird, daß die Enden der Jahresringe nicht auf ein und derselben Schnittfläche austreten und die mittlere Außenfläche parallel zur Schnittfläche des Rundholzabschnittes oder faserparallel bearbeitet wird, und daß dann jeweils vier sortierte Einzelelemente entsprechend paarweise längsachsen- und querschnittsgewendet zu einem Holzhohlbalken zusammengeleimt werden.The invention relates to a method for manufacturing a wooden hollow beam, rectangular in outline Composite construction, which consists of several, in the longitudinal direction of the wooden hollow beam, with each other connected, enclosing a cavity Individual elements is composed, being used for production of the individual elements of the hollow wooden beam to be manufactured First, one each from conical log sections Core plank is cut out, being a cuboid Core plank with a cut parallel to the core and a wedge-shaped core plank with a fiber parallel Cut is obtained and each of the two thereby resulting outer trunk segments with three separate External surfaces is provided and then the dried trunk outer segments perpendicular to Cutting surface for the core plank are separated, whereby the cutting surface dividing the outer segments is that the ends of the annual rings are not on one and emerge from the same cut surface and the middle outer surface parallel to the cut surface of the log section or processed parallel to the fiber, and that then four sorted individual elements accordingly in pairs turned longitudinally and cross-sectioned to one Hollow wooden beams are glued together.
Aus dem Stand der Technik sind die verschiedensten Holz-Hohlbalken bekannt. So z. B. die Formierung entsprechend der SE-115 667, die allerdings den gravierenden Nachteil hat, die Nutzung nur "ganzheitlich" vorzusehen; d. h. die Einzelteile aus einem Rundholz werden einschließlich der Kernbereiche genutzt zu einem Balken quadratischen Querschnittes; wobei die Stammkernbereiche die Ecken des Balkens bilden, dies wirkt sich nachteilig auf die Jahrringstrukturierung aus; es gibt Risse. Bei dieser Methode steht nur die reine Ausbeute im Vordergrund.The most varied are from the prior art Hollow timber beams known. So z. B. the formation accordingly the SE-115 667, but the serious one The disadvantage is that the use is only "holistic"; d. H. the individual parts are made from a log including the core areas used to form a bar square cross section; being the core core areas form the corners of the bar, this works adversely affects tree ring structuring; it there are cracks. With this method only the pure yield stands in the foreground.
Durch die EP-A-0 388 507 sind zwar auch Möglichkeiten von kombinierten Einzelstücken aus unterschiedlichen Rundholzabschnitten erwähnt, bei diesen Holzbalkenformbildungen und den Verfahrensweisen ist jedoch nicht einbezogen, daß die Abtrennung vom Rundholzabschnitt zu keiner Definierung/Katalogisierung führen kann, sondern der für viele Bereiche wichtige Nutzungsraster grundsätzlich erst am halbholzähnlichen Vormaterial zu ermitteln ist. Die EP-A-0 388 507 beschreibt zwar gewisse Balkenformen, jedoch nicht mit dem vorrangigen Ziel, die zwangsläufig unterschiedlichen Rohholzformen über die Kombinationen unterschiedlich großer Einzelelemente, wobei dann die Baumkantenbereiche wegen Überschreitung des Balkenmittelpunktes abzuarbeiten sind, zu sinnvollen Balkenquerschnitten zu nutzen. Kombinationen aus unterschiedlichen Rohholzdurchmessern zur Bildung nur eines Querschnittes (der in etwa dem des mittleren Durchmessers der eingesetzten Durchmesserreihe entspricht) sind nicht vorgesehen.EP-A-0 388 507 also offers possibilities of combined individual pieces from different Round timber sections mentioned in these wooden beam formations and the procedures, however, is not included that the separation from the log section too no definition / cataloging can lead, but the basic usage pattern for many areas only to be determined on the semi-timber-like primary material is. EP-A-0 388 507 describes certain Bar shapes, but not with the primary aim of the inevitably different forms of raw wood the combinations of individual elements of different sizes, then the tree edge areas due to crossing of the center of the beam are to be processed, to use meaningful beam cross sections. Combinations from different raw wood diameters Formation of only one cross section (roughly that of the average diameter of the range of diameters used corresponds) are not provided.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Holzhohlbalken zu schaffen, das eine größere Freizügigkeit bei der Zusammenstellung von Einzelelementen zu einem Hohlbalken gestattet, zu einer besseren Formstabilität bei wechselnder Feuchte und im Langzeitverhalten führt und ein sicheres Schließen der Klebefugen gewährleistet und mit dem in wirtschaftlicher Verfahrensweise die optimalste Ausbeute bei geringstem Ausschuß erreicht wird.The invention has for its object a method to create hollow wooden beams that greater freedom of movement when compiling Individual elements to a hollow beam allowed to one better dimensional stability with changing moisture and in Long-term behavior leads and a safe closing of the Adhesive joints guaranteed and with that in economical The best possible yield with the least Committee is reached.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen
des Anspruches 1 gelöst.This object is achieved with the features
of
Faserparalleles Sägen bringt enorme Vorteile bezüglich Rissebildung, Trocknungsverhalten und Belastbarkeiten. Die aus dem keilartigen Mittelstück entstehenden Vormaterialien können wiederum zur Holzhohlbalkenfertigung genutzt werden. Beim faserparallelen Sägen entfällt also nur ein kleiner Teil auf das, was nicht zu Holzbalken zu verarbeiten ist.Sawing parallel to fibers brings enormous advantages in terms of Crack formation, drying behavior and resilience. The materials from the wedge-like center piece can in turn be used for hollow beam production be used. In the case of sawing parallel to fibers, there is no need so only a small part of what is not to wooden beams is to be processed.
Nachdem die Vormaterialien geschnitten sind, werden diese nassen Vormaterialien erfindungsgemäß vor der Sortierung und Trocknung entsprechend der tatsächlichen Formen und optimal möglichen Nutzungen mehrflächig vorbearbeitet. Vorteilhaft werden zur Erreichung optimaler Sortier- und Trocknungsergebnisse Entspannungsschlitze eingebracht und die Baumkantenbereiche bearbeitet.After the raw materials are cut these wet materials according to the invention before Sorting and drying according to the actual Forms and optimally possible uses pre-processed over multiple areas. Be advantageous to achieve more optimal Sorting and drying results introduced and processed the tree edge areas.
Unterschiedlichste Rohholzdurchmesser führen zu einer Vielzahl von Nutzungsrastern. Der Markt fordert aber keine allzu große Auswahl an Querschnittsabmessungen, d. h. es gingen enorme Rohstoffnutzungsmöglichkeiten dann verloren, wenn die Stammaußensegmente paarweise auf die Querschnittsabmessung oder gar auf die Rundholzformen bezogen würde. Für die optimale Rohstoffnutzung werden die Holzhohlbalkenquerschnitte aus unterschiedlich großen Einzelelementen gebildet. Die Baumkantenbereiche werden als schräge Flachen zwischen den Fügeflächen so abgearbeitet, daß sich diagonal gegenüber angeordnete Größen in Balkenmittelpunkt nicht überschneiden, so daß es möglich ist, querschnittsgleiche Holzholbalken aus durchmesserunterschiedlichen Rundhölzern zu fertigen.Different raw wood diameters lead to one Variety of usage patterns. The market is demanding not too large a selection of cross-sectional dimensions, d. H. there were enormous possibilities of using raw materials then lost when the trunk outer segments in pairs on the cross-sectional dimensions or even on the round wood shapes would be related. For the optimal use of raw materials the wooden hollow beam cross sections are different large individual elements. The tree edge areas are called sloping surfaces between the Joining surfaces processed so that they face each other diagonally not arranged sizes in the center of the bar overlap so that it is possible to have the same cross-section Wooden beams made of different diameters To manufacture round timbers.
Trocknungsschwund entwickelt sich in erster Linie in Richtung der Jahrringe, und der Feuchtigkeitsentzug vollzieht sich im wesentlichen quer zu den Jahresringen vom Kern nach außen hin. Bei nur zwei geleimten Fügeflächen (je zwei zusammengesetzte Einzelelemente) gäbe es nahezu keine Schwindungen, Diffusionen oder Spannungen. Wegen der Schubspannungen in h0,5 müssen aber die Leim- bzw. Fügeflächen in horizontaler Lage nicht nur vorhanden, sondern möglichst breit sein. Erfindungsgemäß wird dies dadurch erreicht, daß vorzugsweise die senkrechten Leimflächen durch minimale und die Flächenmomente (cm3 / cm4) vernachlässigbare Fügeflächenabstufungen verkleinert werden, wodurch die Vergrößerungen der Lochrandflächen die Vorgänge aus Quellungen, Schwindungen, Diffusionen oder Spannungen beherrschen.Drying shrinkage develops primarily in the direction of the annual rings, and the removal of moisture takes place essentially transversely to the annual rings from the core to the outside. With only two glued joining surfaces (two assembled individual elements) there would be almost no shrinkage, diffusion or tension. Because of the shear stresses in h0.5, the glue or joint surfaces must not only be available in a horizontal position, but also as wide as possible. According to the invention this is achieved in that the vertical glue surfaces are preferably reduced by minimal and the surface moments (cm 3 / cm 4 ) negligible joining surface gradations, whereby the enlargement of the hole edge surfaces dominate the processes of swelling, shrinkage, diffusion or tension.
