Abstract
Description
Die Erfindung betrifft eine Verbindung gemäß dem Oberbegriff des Anspruches 1.
Im Ingenieurholzbau müssen aufgrund der dort typischen großräumigen Strukturen und Spannweiten regelmäßig Holz- und Metallteile miteinander lasttragend verbunden werden. Insbesondere müssen regelmäßig als Brettschichtholzteile ausgebildete Stabelemente an Metall- bzw. Stahlanker angeschlossen werden, um Verbindungsknoten einer Tragwerksstruktur hinreichend belastbar realisieren zu können.The invention relates to a compound according to the preamble of
In timber engineering, wooden and metal parts must regularly be connected to one another load-bearing due to the typical large-scale structures and spans. In particular, regularly trained as glued laminated timber members rod elements must be connected to metal or steel anchors to realize connection nodes of a structural structure sufficiently strong.
Dazu besitzen die Metall- bzw. Stahlanker starke Flanschbleche oder Hohlprofilabschnitte, die in entsprechende Schlitze oder dem Querschnitt des jeweiligen Hohlprofils angepasste Ausnehmungen des Holzteiles eingesetzt und dort durch Dübel befestigt werden, die die einander gegenüberliegenden Holz- und Metallflächen im Überlappungsbereich der miteinander verbundenen Holz- und Metallteile etwa senkrecht durchsetzen.For this purpose, the metal or steel anchors have strong flange plates or hollow profile sections, which are inserted into corresponding slots or the cross-section of the respective hollow profile adapted recesses of the wood part and fastened there by dowels that the opposite wood and metal surfaces in the overlapping area of interconnected wood and pass metal parts approximately vertically.
Diese Verbindungen zeichnen sich einerseits durch eine hohe Belastbarkeit und andererseits durch eine gewisse Nachgiebigkeit aus.These compounds are characterized on the one hand by a high load capacity and on the other hand by a certain flexibility.
Gemäß der AT 316 833 können Montagestoßenden von Traggliedern einer Holzleimbaukonstruktion am Ende eines Traggliedes, an einer Wand oder an einem Sturz eines Bauwerkes dadurch befestigt werden, dass zwischen den Holzschichten des Traggliedes Stahllamellen eingeklebt oder mit mechanischen Mitteln wie Krallenplatten, Schrauben, Dübeln oder dergleichen an den Holzlamellen befestigt und an ihren aus dem Tragglied herausragenden Enden mit Ringen oder dgl. versehen sind, die scharnierartig zwischen entsprechende Ringe oder dergleichen eines anderen Bauwerkteiles eingreifen und mit den letzteren Ringen durch ein alle Ringe durchsetzendes stiftartiges Verbindungsmittel, das mit Kunstharzbindemittel fixiert sein kann, gekuppelt sind.According to AT 316 833, assembly butt ends of support members of a wood glue construction can be provided at the end of a support member, against a wall or a lintel of a structure be attached that glued between the wood layers of the support member steel slats or attached by mechanical means such as claw plates, screws, dowels or the like to the wood slats and provided at their protruding from the support member ends with rings or the like., Which are hingedly between corresponding rings or the like engage another structural part and with the latter rings by a pin-type connecting means penetrating all rings, which can be fixed with synthetic resin binder, are coupled.
Die DE 44 45 018 A1 zeigt, dass die Metallanker in den entsprechend geformten Ausnehmungen der Holzteile auch durch Klebung befestigt werden können, so daß keine Dübel notwendig sind. Außerdem werden in Fig. 11 dieser Druckschrift aufliegend auf den Holzteilen anbringbare Nagelplatten dargestellt, die einerseits mittels an ihnen angeformter Nägel bzw. Stifte oder dgl. mit den Holzteilen verbunden und andererseits zusätzlich mit den Holzteilen flächig verklebt sind.DE 44 45 018 A1 shows that the metal anchors can be fixed in the correspondingly shaped recesses of the wooden parts by gluing, so that no dowels are necessary. In addition, in Fig. 11 of this document lying on the wooden parts attachable nail plates are shown, which are connected on the one hand by means of molded nails or pins or the like. With the wooden parts and on the other hand additionally glued flat with the wood parts.
In der DE 39 23 471 A1 ist vorgesehen, an Stab- und Balkenenden oder Zwischenknoten in Schichtholzteilen Metall- oder Stahllamellen zwischen den Holzschichten einzuleimen. Zwischen einigen benachbarten Lamellen kann nach teilweiser Entfernung des an sich dazwischen angeordneten Brettschichtholzes eine Anschlußplatte eingeschoben werden, die dann durch Bolzen gehaltert wird, die entsprechende Bohrungen in der Anschlußplatte, in den Lamellen sowie verbleibenden Brettschichtholzteilen durchsetzt. Eine ähnliche Anordnung wird auch in der DE 41 00 044 A1 dargestellt.In DE 39 23 471 A1 is proposed to einzuleimen rod and beam ends or intermediate nodes in laminated wood parts metal or steel blades between the layers of wood. Between some adjacent lamellae, a terminal plate can be inserted after partial removal of the interposed glued laminated timber, which is then supported by bolts, the corresponding holes in the terminal plate, in the slats and remaining Interspersed with glued laminated timber parts. A similar arrangement is also shown in DE 41 00 044 A1.
Aus der DE 25 43 085 A1 ist es bekannt, an den Enden eines Brettschichtholzteiles zwischen den Brettschichten flachbandartige Schenkel von U-Bügeln einzukleben, und zwar derart, dass die Mittelbereiche der U-Bügel außerhalb des Brettschichtholzteiles zugängliche Ösen bilden. Damit besteht die Möglichkeit, zwei derartige Schichtholzteile derart aneinander anstoßen zu lassen, dass die Ösen der beiden Teile miteinander fluchten. Durch Einsetzen von Bolzen in diese Ösen können dann die beiden Brettschichtholzteile miteinander auf Stoß verbunden werden. Zur Sicherung werden die Bolzen in den Ösen mit Kunstharzbindemittel fixiert.From DE 25 43 085 A1 it is known to glue flat-band-like legs of U-brackets to the ends of a glued laminated timber part between the board layers, in such a way that the middle regions of the U-brackets outside the glued laminated timber part form accessible eyelets. This makes it possible to have two such laminated wood pieces abut each other such that the eyelets of the two parts are aligned. By inserting bolts in these eyes then the two glued laminated timber parts can be joined together on impact. To secure the bolts are fixed in the eyelets with synthetic resin binder.
Aufgabe der Erfindung ist es nun, eine besonders hoch belastbare und sehr steife Verbindung zwischen lastführenden Holz- und Metallelementen für den Ingenieurholzbau zu schaffen.The object of the invention is therefore to provide a particularly high-strength and very rigid connection between load-bearing wood and metal elements for timber engineering.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of
Mit der Erfindung wird eine überraschende Erhöhung der Steifigkeit und Belastbarkeit der Verbindung zwischen den Metallankern und dem Holzkörper erreicht.With the invention, a surprising increase in the rigidity and resilience of the connection between the metal anchors and the wood body is achieved.
Dies dürfte einerseits darauf zurückzuführen sein, dass die Stahlanker durch ihre Verklebung mit dem Holzteil sehr fest gehalten werden. Andererseits dürfte der Sitz der Dübel, die zweckmäßig aus einem ähnlichen Metall wie die Metallanker bestehen, durch das an den Dübeln vergossene Klebermaterial wesentlich verbessert und verfestigt werden. Im übrigen wird das Holzteil durch das Klebermaterial in Längs- und Querrichtung verfestigt.On the one hand, this may be due to the fact that the steel anchors are very strong due to their bonding with the wooden part being held. On the other hand, the seat of the dowels, which expediently consist of a metal similar to the metal anchors, should be substantially improved and strengthened by the adhesive material cast on the dowels. Moreover, the wood part is solidified by the adhesive material in the longitudinal and transverse directions.
Vorteilhaft ist, dass die Verbindung zwischen Metallanker und Holzteil auch erhebliche Biegemomente und/oder Torsionsmomente mit beliebigem Richtungssinn aufnehmen kann.It is advantageous that the connection between the metal anchor and wood part can also absorb significant bending moments and / or torsional moments with any sense of direction.
Vorzugsweise werden Zwei-Komponenten-Kleber eingesetzt, beispielsweise Epoxitharze bzw. Melanimharze.Preferably, two-component adhesives are used, for example epoxy resins or melamine resins.
Im Übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der besonders bevorzugte Ausgestaltungen der Erfindung beispielhaft dargestellt werden.Incidentally, with regard to preferred features of the invention, reference is made to the claims and the following explanation of the drawing, based on the particularly preferred embodiments of the invention are shown by way of example.

Die in der Zeichnung angegebenen Bemessungen sind beispielhaft und sollen keinerlei Beschränkung des Schutzumfanges darstellen.The dimensions given in the drawing are examples and should not be construed as limiting the scope of protection.
Der in den Fig. 1 und 2 dargestellte Körper besitzt einen im Querschnitt rechteckigen stabförmigen Holzkörper 1, welcher als Brettschichtholzteil ausgebildet ist. Innerhalb des Holzkörpers 1 sind zwei zu den großen Längsseiten des Holzkörpers 1 parallele und zu dessen schmalen Längsseiten sowie zu dessen Stirnenden hin offene Schlitze 2 ausgebildet.The body shown in Figs. 1 and 2 has a rectangular cross-section rod-shaped
In die vorgenannten Schlitze 2 sind flachbandartige, aus stabilem Stahlblech hergestellte Metallanker 3 eingesetzt, die aus den Stirnenden des Holzkörpers 1 herausragende freie Endbereiche besitzen. Die Metallanker 3 sind mit dem Holzkörper 1 durch Metalldübel formschlüssig verbunden, die in den Fig. 1 und 2 nicht dargestellt sind. Diese Metalldübel durchsetzen den Metallanker 3 und den Holzkörper 1 quer zur Ebene des Metallankers und haben eine Länge, die der Gesamtdicke von Holzkörper 1 und Metallanker 3 in Dübellängsrichtung entspricht.In the
Die Dicke des die Metallanker 3 bildenden Stahlbleches ist etwas geringer als der Abstand der die Schlitze 2 begrenzenden Wandungen des Holzkörpers 1. Dementsprechend werden zwischen den vorgenannten Wandungen des Holzkörpers 1 und den zugewandten Längsseiten der Metallanker 3 schmale Spalträume ausgebildet. Diese Spalträume sowie die zwischen den Umgangsflächen der Dübel und dem Holzkörper gebildeten Ringspalte sind mit einem Zwei-Komponenten-Epoxidharz ausgegossen, so dass nach dem Aushärten des Harzes ein fester, hoch belastbarer Verbund zwischen dem Holzkörper 1 und den Metallankern 3 geschaffen wird.The thickness of the
Der in den Fig. 3 und 4 dargestellte Verbundkörper unterscheidet sich vom Verbundkörper der Fig. 1 und 2 dadurch, dass die Schlitze 2 in Längsrichtung des Holzkörpers 1 ebenso wie die darin aufgenommenen Bereiche der Metallanker 3 eine verminderte Länge besitzen.The composite body shown in FIGS. 3 and 4 differs from the composite body of FIGS. 1 and 2 in that the
Im Übrigen zeigen die Fig. 3 und 4, dass die Metallanker 3 einerseits in die Schlitze 2 des Holzkörpers 1 mit Zwei-Komponenten-Epoxidharz eingegossen und andererseits darüber hinaus durch Dübel 4 fixiert sind, die aus gleichartigem Metall wie die Metallanker bestehen und entsprechende Bohrungen im Holzkörper 1 sowie in den Metallankern 3 durchsetzen. Diese Bohrungen sind senkrecht zu den großen Seitenflächen des Holzkörpers 1 sowie der Metallanker 3 ausgerichtet. E-rindungsgemäß erfolgt das Vergießen des Epoxidharzes nach Anordnung der Dübel 4, so dass auch die Dübel 4 durch Verguß im Holzkörper 1 sowie in den Metallankern 3 zusätzlich fixiert werden.Incidentally, FIGS. 3 and 4 show that the
Im Hinblick auf eine besonders starke Verbindung zwischen Metallankern 3 und Holzkörper 1 sind die Dübel 4 gemäß Fig. 3 jeweils in zwei Reihen angeordnet.With a view to a particularly strong connection between
Grundsätzlich sind jedoch auch nur eine Dübelreihe oder mehr als zwei Dübelreihen möglich.In principle, however, only one dowel row or more than two dowel rows are possible.
Anstelle des oben genannten Epoxidharzes können grundsätzlich bei allen Ausführungsformen auch andere Kleber, z.B. Melaminharze oder ein Polyurethan-Leim, verwendet werden.In principle, instead of the above-mentioned epoxy resin, other adhesives, e.g. Melamine resins or a polyurethane glue.
Die Vergußmasse ist parallel zu ihrer Schichtebene hochbelastbar, wobei eine mit der Belastung nahezu linear ansteigende, jedoch sehr geringe Verschiebung des Metalls relativ zum Holzkörper 1 auftritt.The potting compound is highly resilient parallel to its layer plane, with a load almost linearly increasing, but very small displacement of the metal relative to the
Die Ausbildung der freien, aus dem Holzkörper 1 herausstehenden Enden der Metallanker 3 kann weitestgehend beliebig an die Bedürfnisse des jeweiligen Einbauortes im Bauwerk angepasst sein.The formation of the free, protruding from the
Bei allen zeichnerisch dargestellten Ausführungsformen besitzen die Metallanker 3 glatte Seitenflächen.In all drawings illustrated embodiments, the
Davon abweichend ist es auch möglich, die Metallanker 3, zumindest dessen Abschnitt innerhalb des Holzkörpers 1, geriffelt mit quer zur Längsrichtung des Holzkörpers 1 ausgerichteten rillen- oder rinnenartigen Vertiefungen auszubilden.Deviating from this, it is also possible to form the
Bei einer solchen Ausführungsform kann es zweckmäßig sein, die Breite der Schlitze 2 so zu bemessen, dass die Stahlanker 3 zwischen den Rinnen bzw. Vertiefungen auch durch Kraftschluß innerhalb der Schlitze 2 festgehalten werden, wobei sich das geriffelte Profil der Stahlanker 3 auch etwas in das Holzmaterial "eingraben" kann.In such an embodiment, it may be appropriate to dimension the width of the
Die in den Holzkörper 1 eingeschobenen Bereiche der Metallanker 3 können auch ein von einem Flachband abweichendes Profil, beispielsweise ein Kreuzprofil, besitzen und in entsprechende Kreuzschlitze des Holzkörpers 1 eingeschoben sein.The inserted into the
Desweiteren können die Metallanker 3 (zumindest) innerhalb des Holzkörpers 1 auch als Hohlprofil mit beispielsweise kreisförmigem oder rechteckigem Querschnitt ausgebildet und in holzkörperseitige Ausnehmungen mit entsprechendem Querschnitt aufgenommen sein.Furthermore, the metal anchors 3 (at least) within the
Die dargestellten Verbundkörper können sowohl als Zugstreben als auch - insbesondere - als Druckstreben eingesetzt werden, wobei die Metallanker 3 Teile stabiler Verbindungsknoten zum Anschluss der Streben an andere Bauwerksteile bilden.
Im übrigen kann die erfindungsgemäße Verbindung auch an geknickten Stäben oder Holzteilen vorgesehen sein.The composite bodies shown can be used both as tension struts and - in particular - as compression struts, wherein the metal anchors form 3 parts stable connection node for connecting the struts to other building parts.
Moreover, the compound according to the invention can also be provided on bent rods or wooden parts.
