Abstract

In order to connect wooden structural parts when renovating a building, the invention proposes that the two wooden structural parts (1, 3) to be connected together are first fixed relative to each other, that in at least one side surface of the two wooden structural parts (1, 3) there is worked, for example milled in, a depression (13) which extends beyond the joint region (7) of the two wooden structural parts and into the same. The base of said depression is located in a common plane in the two wooden structural parts (1, 3) and its depth is greater than the thickness of a connecting lamella (11) which is to be adhesively bonded in a following step. After adhesively bonding the first connecting lamella (11), the depression (13) is widened via the first connecting lamella (11) in a direction away from the joint region (7) such that the widened depression (13) has a planar base which extends in a flush manner via the first connecting lamella (11) and beyond into the two wooden structural parts. A further connecting lamella (11) is adhesively bonded in a sheet-like manner into the widened depression (13), after which the sequence of steps for attaching additional connecting lamellae (11) is repeated if required. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Verbinden von wenigstens zwei insbesondere stumpf aneinanderstoßenden, balkenförmigen Holzbauteilen, von denen wenigstens eines fest in ein Gebäude eingebaut ist und bei welchem an den beiden Holzbauteilen wenigstens eine über deren Stoßbereich hinwegreichende, plattenförmige Verbindungslamelle, insbesondere aus Holz, befestigt wird.The invention relates to a method for connecting at least two, in particular butt-jointed, beam-shaped wooden components, at least one of which is permanently installed in a building and in which at least one plate-shaped connecting lamella, in particular made of wood, extending over the joint area is attached to the two wooden components .

Bei der Sanierung von Holzkonstruktionen von Gebäuden, beispielsweise Holzbalkendecken oder Dachstühlen, können und sollen die zumeist fest in das Gebäude eingebauten, kraftübertragenden Balken nicht komplett ausgetauscht werden. Vielmehr soll lediglich der geschädigte Teil des Balkens entfernt und der Balken statt dessen durch ein neues Holzbauteil verlängert werden. Die Verlängerung muß so erfolgen, daß sie wieder Schub-, Längs- und Querkräfte übertragen kann, zumal in der Regel der Auflagerbereich des Balkens geschädigt ist.When renovating wooden structures in buildings, such as wooden beam ceilings or roof trusses, the force-transmitting beams, which are usually permanently installed in the building, cannot and should not be completely replaced. Rather, only the damaged part of the beam should be removed and the beam should instead be extended with a new wooden component. The extension must take place in such a way that it can transmit shear, longitudinal and transverse forces again, especially since the support area of the beam is usually damaged.

Es ist bekannt, zwei Balken durch Anschrauben oder Annageln von U-Profilen aus Stahl kraftschlüssig aneinander anzuschließen. Auch ist es bekannt, Balken durch Anbringen von Beilagen aus Holz miteinander zu verbinden. Die bisher zur Verbindung von Holzbalken benutzten Verfahren hatten jedoch den Nachteil, daß sie entweder nicht materialgerecht, d.h. in Form einer Holzverbindung, durchgeführt wurden oder aber, soweit Holzverbindungen benutzt wurden, daß diese nur unzureichend Kräfte übertragen konnten.It is known to positively connect two beams to one another by screwing or nailing steel U-profiles. It is also known to connect beams to one another by attaching wooden inserts. However, the methods previously used for connecting wooden beams had the disadvantage that they were either not suitable for the material, i.e. in the form of a wood connection were carried out or, if wood connections were used, that these could only transmit insufficient forces.

Es ist Aufgabe der Erfindung, ein Verfahren zum Verbinden mehrerer Holzbauteile anzugeben, das eine hinreichend kraftübertragende Verbindung der Holzbauteile ermöglicht, selbst wenn eines der Holzbauteile fest in ein Gebäude eingebaut ist.It is an object of the invention to provide a method for connecting a plurality of wooden components that enables a sufficiently force-transmitting connection of the wooden components, even if one of the wooden components is permanently installed in a building.

Ausgehend von dem eingangs erläuterten Verfahren, bei welchem die insbesondere balkenförmigen Holzbauteile durch mehrere plattenförmige, ebenfalls vorzugsweise aus Holz bestehende Verbindungslamellen über den Stoßbereich der Holzbauteile hinweg aneinander befestigt werden, wird diese Aufgabe durch folgende Schritte gelöst:

  • a) Die zu verbindenden Holzbauteile werden relativ zueinander fixiert,
  • b) in wenigstens eine Seitenfläche der Holzbauteile wird eine über den Stoßbereich hinweg in die Holzbauteile sich erstreckende Vertiefung eingearbeitet, insbesondere eingefräst, deren Boden in den Holzbauteilen in einer gemeinsamen Ebene liegt und deren Tiefe größer ist als die Dicke der Verbindungslamelle,
  • c) in die Vertiefung wird eine erste Verbindungslamelle eingesetzt und flächig am ebenen Boden der Vertiefung befestigt,
  • d) die Vertiefung wird von dem Stoßbereich weggerichtet über die erste Verbindungslamelle hinaus erweitert, derart, daß die erweiterte Vertiefung einen bündig über die erste Verbindungslamelle hinweg in die Holzbauteile hinein sich erstreckenden ebenen Boden hat,
  • e) in die erweiterte Vertiefung wird eine weitere Verbindungslamelle eingesetzt und flächig am Boden der erweiterten Vertiefung sowohl im Bereich der darunter liegenden Verbindungslamelle als auch der Holzbauteile befestigt, wobei die Schrittfolge d) und e) zumindest einmal, vorzugsweise jedoch mehrmals durchgeführt wird.
On the basis of the method explained at the outset, in which the, in particular, beam-shaped wooden components are fastened to one another by means of a plurality of plate-shaped, also preferably made of wood, connecting slats over the joint area of the wooden components, this task is accomplished by the following steps:
  • a) The wooden components to be connected are fixed relative to each other,
  • b) in at least one side surface of the wooden components, an indentation extending into the wooden components across the joint area is machined, in particular milled, the bottom of which lies in the wooden components in a common plane and whose depth is greater than the thickness of the connecting lamella,
  • c) a first connecting lamella is inserted into the recess and is flat on the flat bottom of the recess attached,
  • d) the depression is extended away from the joint area beyond the first connecting lamella, in such a way that the expanded depression has a flat floor which extends flush over the first connecting lamella and into the wooden components,
  • e) a further connecting lamella is inserted into the enlarged depression and is attached flatly to the bottom of the enlarged depression both in the area of the underlying lamella and the wooden components, the sequence of steps d) and e) being carried out at least once, but preferably several times.

Dem vorstehend erläuterten Verfahren liegt die Idee zugrunde, die miteinander zu verbindenden Holzbauteile am vorgesehenen Einbauort durch eine Vielzahl sandwichartig übereinander liegender Verbindungslamellen mit gestufter Länge miteinander zu verbinden und zwar so, daß der Lamellenstapel über eine Abtreppung in die beiden Holzbauteile eingreift. Wesentlich ist, daß die Verbindungslamellen nacheinander eingebaut werden und jeweils vor dem Einbau jeder Lamelle eine ebene Auflagefläche hergestellt wird, auf der die einzubauende Lamelle auf ihrer gesamten Fläche aufliegen kann. Auf diese Weise wird eine Verbindung zwischen den beiden Holzbauteilen geschaffen, die in hohem Maß Kräfte übertragen kann.The above-explained method is based on the idea of connecting the wooden components to be connected to one another at the intended installation location by means of a plurality of sandwich-like superimposed connecting lamellae with a stepped length, in such a way that the stack of lamellae engages in the two wooden components via a step. It is essential that the connecting lamellae are installed one after the other and that before each lamella is installed, a flat contact surface is produced on which the lamella to be installed can rest on its entire surface. In this way, a connection is created between the two wooden components, which can transmit forces to a high degree.

Um in jedem Fall Vertiefungen mit ebenem Boden in den Verbindungsbereich der Holzbauteile einarbeiten zu konnen, wird zweckmäßigerweise im Schritt d) die Dicke der darunter liegenden Verbindungslamelle bei der Herstellung des bündig ebenen Bodens der erweiterten Vertiefung verringert. Mit anderen Worten, die Dicke der einzubauenden Lamelle wird größer gewählt, als es der Enddicke im fertig eingebauten Zustand entspricht, und die Verbindungslamelle wird beim Erweitern der Vertiefung abgeflacht.In order to be able to incorporate depressions with a flat bottom into the connecting area of the wooden components, the thickness of the connecting lamella below is expediently reduced in step d) during the production of the flush, flat bottom of the enlarged depression. In other words, the thickness of the one to be installed The lamella is chosen to be larger than the final thickness in the fully installed state, and the connecting lamella is flattened when the recess is widened.

Die Vertiefungen werden vorzugsweise gefräst, insbesondere mit einer Oberfräse mit einem mit hoher Drehzahl rotierenden Stiftfräser. Um einen exakt ebenen Boden der Vertiefung herstellen zu können, wird an den relativ zueinander fixierten Holzbauteilen bevorzugt eine an den Holzbauteilen gehaltene Führungsvorrichtung angebracht, die eine Verschiebung der Oberfräse in einer Ebene erlaubt. Es versteht sich, daß die Holzbauteile vor dem Einbau der Verbindungslamellen mit einer Rohabtreppung versehen werden können, die nachfolgend beim Einbau der Verbindungslamellen nur noch nachgearbeitet werden muß.The depressions are preferably milled, in particular using a router with a pin mill rotating at high speed. In order to be able to produce an exactly flat bottom of the depression, a guide device which is held on the wooden components and which allows the router to be displaced in one plane is preferably attached to the wooden components which are fixed relative to one another. It goes without saying that the wooden components can be provided with a raw staircase before the connection slats are installed, which only has to be reworked subsequently when the connection slats are installed.

Die Verbindungslamellen können am Boden der Vertiefung angenagelt oder angeschraubt werden, werden aber zweckmäßigerweise flächig an dem Boden der Vertiefung angeklebt. Für hochfeste Verklebungen kann zumindest über den Verbindungsbereich der Holzbauteile ein Klimazelt gesetzt werden, in welchem der Verbindungsbereich entsprechend den Klebevorschriften temperiert und auf einer bestimmten Luftfeuchtigkeit gehalten werden kann.The connecting lamellae can be nailed or screwed to the bottom of the depression, but are expediently adhesively bonded to the bottom of the depression. For high-strength bonds, a climate tent can be placed at least over the connection area of the wooden components, in which the connection area can be tempered in accordance with the adhesive regulations and kept at a certain atmospheric humidity.

Die Vertiefungen, deren Lange jeweils gleich der darin einzusetzenden Verbindungslamelle ist, werden zweckmäßigerweise zur jeweils darunter liegenden Verbindungslamelle symmetrisch erweitert. Für besonders belastbare Verbindungen hat es sich in diesem Zusammenhang als zweckmäßig erwiesen, wenn die Breite der Erweiterung der Vertiefung quer zum Stoßbereich, d.h. in Längsrichtung balkenförmiger Holzbauteile, gleich oder größer ist als längs des Stoßbereichs, also quer zum Balken. Derartig bemessene Verbindungslamellen überlappen in einem hinreichend großen Flächenbereich mit Flächen der Holzbauteile.The depressions, the length of which is in each case the same as the connecting lamella to be inserted therein, are expediently expanded symmetrically to the connecting lamella below them. For particularly resilient connections, it has proven to be expedient in this connection if the width of the widening of the depression transversely to the joint area, ie in the longitudinal direction of beam-shaped wooden components, is equal to or greater than along the joint area, that is to say transversely to the beam. Such Dimensioned connecting lamellae overlap with surfaces of the wooden components in a sufficiently large area.

Vorzugsweise werden auf einander gegenüberliegenden Seiten der beiden Holzbauteile Verbindungslamellenstapel eingebaut, um den Querschnitt der Holzbauteile besonders häufig und auch symmetrisch abtreppen zu können. Die auf gegenüberliegenden Seiten angeordneten Verbindungslamellenstapel werden jedoch zweckmäßigerweise quer zum Stoßbereich, d.h. in Längsrichtung der balkenförmigen Holzbauteile, um etwa die halbe Breite der Erweiterungen der Vertiefungen gegeneinander versetzt. Die in Längsrichtung an den Stirnenden der Verbindungslamellen sich ergebenden Stoßfugen werden auf diese Weise gleichmäßig längs der Holzbauteile verteilt und zwar so, daß in jeder Querschnittsfläche maximal nur eine Stoßfuge ist.Connection lamella stacks are preferably installed on opposite sides of the two wooden components in order to be able to step off the cross section of the wooden components particularly frequently and also symmetrically. However, the connecting lamella stacks arranged on opposite sides are expediently arranged transversely to the joint area, i.e. in the longitudinal direction of the beam-shaped wooden components, offset by about half the width of the extensions of the depressions. The butt joints resulting in the longitudinal direction at the ends of the connecting slats are distributed evenly along the wooden components in such a way that there is at most only one butt joint in each cross-sectional area.

Die Verbindungslamellen bestehen unter dem Gesichtspunkt einer materialgerechten Verbindung bevorzugt aus Holz. Es versteht sich, daß die Verbindungslamellen nicht aus derselben Holzsorte bestehen müssen, aus der die Holzbauteile hergestellt sind. Alternativ können auch Holzsorten höherer Festigkeit oder aber Verbindungslamellen aus Nichtholzwerkstoffen verwendet werden. Insbesondere kann daran gedacht werden, flexible Verbindungslamellen zu benutzen, um beispielsweise bei Fachwerkkonstruktionen Gelenkknoten zu erreichen.From the point of view of a material-appropriate connection, the connecting lamellae preferably consist of wood. It goes without saying that the connecting lamellae do not have to consist of the same type of wood from which the wooden components are made. Alternatively, wood types of higher strength or connecting lamellas made of non-wood materials can be used. In particular, it can be considered to use flexible connecting lamellae in order, for example, to achieve articulated nodes in truss constructions.

The invention will be explained in more detail below with reference to a drawing. Here shows:

Fig. 1 zeigt einen im Zuge einer Sanierung eines Gebäudes um einen Holzbalken 1 verlängerten Holzbalken 3, beispielsweise eines Dachstuhls oder einer Holzbalkendecke, der mit dem Gebäude fest verbunden ist, hier mit seinem Ende im Mauerwerk 5 verankert ist, und ein tragendes Konstruktionsteil des Gebäudes bildet. Auf einander gegenüberliegenden Längsseiten der Balken 1, 3, die mit ihren Stirnenden unter Bildung einer Stoßfuge 7 aneinander grenzen, sind Stapel 9 aus jeweils mehreren plattenförmigen Verbindungslamellen 11 in passende Vertiefungen 13 eingeklebt. Die Länge jeder Verbindungslamelle 11 ist gleich der Länge der Vertiefung 13 bemessen, in die sie eingesetzt ist. Innerhalb jedes Stapels 9 sind die Längen der Verbindungslamellen 11 abgestuft und nehmen vom Inneren der Balken 1, 3 nach außen hin zu. Die Überstände, mit der eine jeweils äußere Verbindungslamelle 11 die darunter liegende, innere Verbindungslamelle in Längsrichtung der Balken 1, 3 überragt, sind zur Längsmitte der innersten Verbindungslamelle 11 symmetrisch. Vorzugsweise sind sämtliche Überstände gleich groß, wobei die Länge jedes Überstands quer zu Stoßfuge 7, d.h. in Längsrichtung der Balken 1, 3 gleich oder größer ist als die Breite der Verbindungslamellen 11 längs der Stoßfuge 7, d.h. quer zu den Balken 1, 3. Die Überstände haben damit quadratische oder in Längsrichtung der Balken 1, 3 rechteckige Form. Wie aus Fig. 1 zu ersehen ist, sind die beiden Stapel 9 in Längsrichtung der Balken 1, 3 um die halbe Länge der Überstände der einzelnen Verbindungslamellen 11 gegeneinander versetzt, um zu verhindern, daß mehr als eine stirnseitige Stoßfuge am Ende jeder Verbindungslamelle 11 in derselben Querschnittsebene der Balken 1, 3 liegt. Die Verbindungslamellen bestehen aus Holz und haben im wesentlichen in Längsrichtung der Balken 1, 3 verlaufende Fasern.Fig. 1 shows a wooden beam 3 extended during the renovation of a building by a wooden beam 1, for example a roof truss or a wooden beam ceiling, which is firmly connected to the building, here anchored with its end in the masonry 5, and a load-bearing structural part of the building forms. On opposite longitudinal sides of the beams 1, 3, which adjoin one another with their ends to form a butt joint 7, stacks 9, each made up of a plurality of plate-shaped connecting lamellae 11, are glued into suitable recesses 13. The length of each connecting lamella 11 is equal to the length of the recess 13 in which it is inserted. The lengths of the connecting lamellae 11 are stepped within each stack 9 and increase from the inside of the beams 1, 3 to the outside. The protrusions with which an outer connecting lamella 11 projects above the underlying inner connecting lamella in the longitudinal direction of the beams 1, 3 are symmetrical to the longitudinal center of the innermost connecting lamella 11. Preferably, all the protrusions are of equal size, the length of each protrusion transverse to the butt joint 7, ie in the longitudinal direction of the beams 1, 3 being equal to or greater than the width of the connecting slats 11 along the butt joint 7, ie transversely to the beams 1, 3 Overhangs thus have a square shape or a rectangular shape in the longitudinal direction of the beams 1, 3. As can be seen from Fig. 1, the two stacks 9 are offset in the longitudinal direction of the beams 1, 3 by half the length of the projections of the individual connecting lamellae 11 to prevent more than one end joint at the end of each connecting lamella 11 in the same cross-sectional plane of the beams 1, 3. The connecting slats are made of wood and have fibers running essentially in the longitudinal direction of the beams 1, 3.

Für die Verlängerung des Balkens 3 aufgrund einer Sanierung, bei welcher geschädigte Abschnitte des Balkens 3 herausgeschnitten werden, wird der Balken 1 zunächst in Flucht des Balkens 3 fixiert, beispielsweise durch nicht näher dargestellte, vorübergehend angenagelte Latten oder dergleichen oder gegebenenfalls durch nach erfolgter Sanierung entfernte Stützkonstruktionen fixiert. Sodann wird an den fixierten Balken eine bei 15 angedeutete Führung für eine Fräsvorrichtung, beispielsweise eine nicht näher dargestellte Oberfräse oder dergleichen, angebracht, mit deren Hilfe im Verbindungsbereich der Balken 1, 3 ebene Flächen gefräst werden können, die sich über die Stoßfuge 7 hinweg parallel zu einer der Balkenflächen in beide Balken 1, 3 hineinerstrecken. Mit Hilfe der Fräsvorrichtung wird nun die Vertiefung 13 für die innerste und damit kürzeste Verbindungslamelle 11 symmetrisch zur Stoßfuge 7 eingefräst und zwar so, daß die Vertiefung einen ebenen, bündig in die beiden Balken 1, 3 übergehenden Boden hat. Sodann wird die innerste Verbindungslamelle 11 flächig eingeklebt, wobei der Klebepreßdruck durch eine hydraulische Presse oder aber durch Nagel- oder Schraubverbindungen erzeugt wird. In einem nächsten Schritt wird die bis zur Außenseite der Balken 1, 3 durchgehende innerste Vertiefung in Längsrichtung der Balken 1, 3 symmetrisch auf die Länge der nächstliegenden Verbindungslamelle erweitert, wobei auch hier die Vertiefung wieder einen ebenen Boden erhält, der sich sowohl über die Erweiterungen als auch die außenliegende Oberfläche der innersten Verbindungslamelle bündig hinwegerstreckt. Zweckmäßigerweise wird hierbei ein Teil der bereits eingeklebten Verbindungslamelle 11 abgetragen. Die wiederum in ihrer Länge der erweiterten Vertiefung angepaßte Verbindungslamelle wird erneut flächig eingeklebt und hierbei auch mit der darunterliegenden Verbindungslamelle verbunden. Diese Einbauschrittfolge wird wiederholt, bis die gewünschte Zahl Verbindungslamellen eingebaut ist. Soweit für die Verklebung spezielle Klimabedingungen eingehalten werden müssen, kann die Verklebung in einem über die Verbindungsstelle der Balken 1, 3 gesetzten Klimazelt erfolgen.For the extension of the beam 3 due to a renovation, in which damaged sections of the beam 3 are cut out, the beam 1 is first fixed in alignment with the beam 3, for example by temporarily nailed battens or the like (not shown in more detail) or, if appropriate, by removal after the renovation has been carried out Support structures fixed. A guide, indicated at 15, for a milling device, for example a router or the like, not shown, is then attached to the fixed beams, with the aid of which flat surfaces can be milled in the connecting area of the beams 1, 3, which parallel across the butt joint 7 stretch into one of the beam surfaces into both beams 1, 3. With the help of the milling device, the recess 13 for the innermost and therefore the shortest connecting lamella 11 is milled symmetrically to the butt joint 7 in such a way that the recess has a flat, flush transition into the two beams 1, 3. The innermost connecting lamella 11 is then glued in over the surface, the adhesive pressure being generated by a hydraulic press or by nail or screw connections. In a next step, the innermost recess extending to the outside of the beams 1, 3 is extended symmetrically in the longitudinal direction of the beams 1, 3 to the length of the closest connecting lamella, the recess again being given a flat bottom, which extends both over the extensions as well as the outer surface of the innermost connecting lamella extends flush. In this case, part of the connecting lamella 11 which has already been glued in is expediently removed. The connecting lamella, which in turn is adapted to the length of the enlarged recess, is again glued in place and is also connected to the connecting lamella below. This installation step sequence will repeated until the desired number of connecting lamellae is installed. If special climatic conditions have to be observed for the bonding, the bonding can take place in a climatic tent placed over the connection point of the beams 1, 3.

Das erfindungsgemäße Verfahren eignet sich nicht nur zur Verlängerung von Holzbalken, sondern auch zur Sanierung komplizierterer Holzkonstruktionen, wie zum Beispiel der Knotenstelle dreier Holzbalken 17, 19, 21, wie dies in Fig. 2 dargestellt ist. Die Stapel der Verbindungslamellen brauchen im Einzelfall nicht auf einander gegenüberliegenden Seiten angeordnet sein, und sie können sich, wie Fig. 2 für einen Stapel 9a von im wesentlichen T-förmiger Verbindungslamellen 11a zeigt, auch durch das gesamte Holzbauteil hindurcherstrecken, so daß der Boden der ersten flächig einzuklebenden Verbindungslamelle bereits durch ein der Form der Lamellen entsprechendes, jedoch ebenfalls eingesetztes Bodenstück 23 gebildet wird. Der Stapel 9a wird im übrigen in der anhand Fig. 1 erläuterten Weise eingebaut.The method according to the invention is suitable not only for the extension of wooden beams, but also for the renovation of more complicated wooden structures, such as the junction of three wooden beams 17, 19, 21, as shown in FIG. 2. The stack of the connecting lamellae need not be arranged on opposite sides in individual cases, and they can, as FIG. 2 shows for a stack 9a of essentially T-shaped connecting lamellae 11a, also extend through the entire wooden component, so that the bottom of the the first surface-to-glue connecting lamella is already formed by a base piece 23 which corresponds to the shape of the lamella but is also inserted. The stack 9a is otherwise installed in the manner explained with reference to FIG. 1.

Bei der Erläuterung der Fig. 1 und 2 ist davon ausgegangen worden, daß die Vertiefungen 13 vollständig bei der Vorbereitung zum Einbau jeder einzelnen Lamelle eingefräst werden. Es versteht sich, daß das Verfahren jedoch auch so durchgeführt werden kann, daß vor dem Einbau der ersten Verbindungslamelle die miteinander zu verbindenden Balken 1, 3 bzw. 17, 19, 21 mit einer Rohabtreppung versehen werden können, die dann beim Einbau der Verbindungslamellen nachbearbeitet, zum Beispiel überfräst, wird.In the explanation of FIGS. 1 and 2 it has been assumed that the recesses 13 are completely milled in preparation for the installation of each individual lamella. It goes without saying that the method can, however, also be carried out in such a way that the beams 1, 3 or 17, 19, 21 to be connected to one another can be provided with a raw staircase before the installation of the first connecting plate, which is then reworked when the connecting plates are installed , for example milled.
