Abstract

Die Erfindung betrifft eine Knotenpunktverbindung für Fachwerke, bzw. Raumfachwerke aus Holzstäben (13) und kugelförmigen Knotenstücken (10) aus Metall, in denen Gewindebohrungen (11) ausgearbeitet sind, deren Achsen sich in jedem Knotenstück-Mittelpunkt schneiden. An den Enden der Holzstäbe (13) sind in Haltegliedern (14) Gewindebolzen (12) drehbeweglich gelagert, die in die Gewindebohrungen (11) der Knotenstücke (10) eingeschraubt werden. Die Halteglieder für die Gewindebolzen waren bisher mehrteilig ausgeführt und mittels Schrauben oder Nägel umständlich an den Holzstäben befestigt. Zur Vereinfachung der Befestigung der Halteglieder (14) an den Holzstäben (13) schlägt die Erfindung vor, die Halteglieder (14) mindestens an ihrem Befestigungsabschnitt als einstückige Profilteile auszubilden und in ihrem Profil (15) entsprechend angepaßten axialen Ausnehmungen (16) in den Stirnenden der Holzstäbe (13) einzukleben. Um eine große Klebefläche zu erreichen, ist das Profil (15) der Halteglieder (14) vielfach verzweigt. Die Erfindung wird hauptsächlich verwendet zur Erstellung preiswerter Raumfachwerke, an die keine besonders hohen statischen Anforderungen gestellt werden.The invention relates to a node connection for trusses or space trusses made of wooden bars (13) and spherical metal node pieces (10), in which threaded holes (11) are worked out, the axes of which intersect at each node piece center. At the ends of the wooden rods (13) threaded bolts (12) are rotatably mounted in holding members (14), which are screwed into the threaded bores (11) of the node pieces (10). The holding links for the threaded bolts were previously made in several parts and were laboriously attached to the wooden bars by means of screws or nails. In order to simplify the fastening of the holding members (14) to the wooden bars (13), the invention proposes to design the holding members (14) at least on their fastening section as one-piece profile parts and in their profile (15) correspondingly adapted axial recesses (16) in the front ends of the wooden sticks (13). In order to achieve a large adhesive surface, the profile (15) of the holding members (14) is often branched. The invention is mainly used to create inexpensive space frameworks, to which no particularly high static requirements are imposed.

Description

Die Erfindung bezieht sich auf eine Knotenpunktverbindung für Holzstäbe von Fachwerken, insbesondere Raumfachwerken, mit an den Enden der Holzstäbe befestigten Haltegliedern für Gewindebolzen, die in Gewindebohrungen von Knotenstücken eingedreht sind.The invention relates to a junction connection for wooden bars of trusses, in particular space trusses, with holding members for threaded bolts fastened to the ends of the wooden bars, which are screwed into threaded holes in node pieces.

Eine derartige Knotenpunktverbindung ist z.B. durch die DE-PS 896 712 und die DE-AS 2 020 242 bekannt geworden. Bei beiden bekannten Konstruktionen bestehen die Knotenstücke aus Stahl oder Leichtmetall, während die Stäbe aus Rund- oder Vierkanthölzern hergestellt sind, wodurch man relativ preiswerte Raumfachwerke erstellen kann, die in vielen Fällen ohne weiteres die statischen Erfordernisse erfüllen. Jede dieser Ausführungen verwendet zur Halterung der Gewindebolzen mehrere U-förmige Bügel, die im einen Fall mittels krallenförmiger Enden und Schrauben an der Außenseite eines Holzstabs befestigt werden und im anderen Fall in axiale Schlitze in den Stirnenden der Holzstäbe eingesteckt und durch querverlaufende Stifte oder Schrauben in dieser Position gehalten sind. Diese Befestigungsarten sind jedoch teileaufwendig und erfordern auch relativ viel Arbeitszeit, da zur Befestigung der Haltebügel zahlreiche Nägel oder Schrauben in das Holz eingetrieben werden müssen. Wenn in dem einen genannten Fall die Haltebügel aus stärkeren Blechen bestehen, müssen diese zur Aufnahme der Nägel oder Schrauben sogar vorgebohrt werden. Die Befestigungsarbeit wird dadurch noch umständlicher.Such a junction connection has become known, for example, from DE-PS 896 712 and DE-AS 2 020 242. In both known constructions, the knot pieces are made of steel or light metal, while the rods are made of round or square timbers, which means that relatively inexpensive space frames can be created, which in many cases easily meet the structural requirements. Each of these versions uses several U-shaped brackets to hold the threaded bolts, which in one case are fastened to the outside of a wooden stick by means of claw-shaped ends and screws, and in the other case are inserted into axial slots in the front ends of the wooden rods and by transverse pins or screws in held in this position. However, these types of attachment are expensive and also require a relatively large amount of work, since numerous nails or screws have to be driven into the wood in order to attach the retaining bracket. If, in the one case mentioned, the holding brackets consist of thicker sheets, these must even be pre-fitted to accommodate the nails or screws be drilled. This makes the fastening work even more cumbersome.

Der Erfindung liegt die Aufgabe zugrunde, derartige Knotenpunktverbindungen weiter zu vereinfachen, so daß sie zeitsparend hergestellt werden können. Schließlich soll auch die Anschlußlänge zwischen den Stabenden und den Knotenstücken weiter reduziert werden.The invention has for its object to further simplify such node connections so that they can be produced in a time-saving manner. Finally, the connection length between the rod ends and the node pieces should also be reduced further.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die Halteglieder mindestens an ihrem Befestigungsabschnitt als einstückige Profilteile ausgebildet und in ihrem Profil angepaßten axialen Ausnehmungen in den Stirnenden der Holzstäbe eingeklebt sind. Dadurch wird die Befestigung eines Halteglieds am Ende eines Holzstabes wesentlich vereinfacht, denn das Halteglied braucht nach Einbringung des Klebstoffes lediglich in die entsprechenden Ausnehmungen eingedrückt zu werden, wobei durch relativ große Klebeflächen nach dem Aushärten des Klebers eine sichere Verankerung des Halteglieds am Holzstabende sichergestellt wird. Zweckmäßig wird das Profil der Halteglieder zur Vergrößerung der Klebefläche vielfach verzweigt ausgebildet. Die Ausnehmungen in den Stirnenden der Holzstäbe können bei verwickelten Profilen relativ einfach z.B. im Kopierfräsverfahren hergestellt werden. Mittels der erfindungsgemäßen Halteglieder lassen sich ferner sehr kurze Anschlußlängen erreichen.According to the invention, this object is achieved in that the holding members are formed at least on their fastening portion as one-piece profile parts and are glued in their profile adapted axial recesses in the ends of the wooden rods. This considerably simplifies the fastening of a holding member at the end of a wooden stick, since the holding member only needs to be pressed into the corresponding recesses after the adhesive has been introduced, with the holding member being securely anchored to the end of the wooden stick after the adhesive has hardened after the adhesive has hardened. The profile of the holding members is expediently designed in many branches to enlarge the adhesive surface. The recesses in the front ends of the wooden rods can be relatively simple e.g. be produced in the copy milling process. Very short connection lengths can also be achieved by means of the holding members according to the invention.

Die Wirtschaftlichkeit wird weiter erhöht, wenn die Halteglieder nach einer weiteren Ausgestaltung der Erfindung aus Strangpreßprofilteilen bestehen. Dies hat den ganz besonderen Vorteil, daß dabei die Klebe-Fläche in einfachster Weise besonders groß ausgeführt werden kann und eine sehr große Grenzfläche zwischen Holz und Anschlußteil zur Kraftübertragung mittels des Klebers genutzt werden kann.The economy is further increased if, according to a further embodiment of the invention, the holding members consist of extruded profile parts. This has the very special advantage that the adhesive surface can be made particularly large in the simplest way and that a very large interface between the wood and the connecting part can be used for power transmission by means of the adhesive.

Wenn gemäß noch einer weiteren Ausgestaltung der Erfindung jedes Halteglied aus einem Strangpreßteil mit sägezahnförmigem oder dgl. Profil besteht oder ein solches enthält, wird die Ausarbeitung der entsprechenden keilförmigen Ausnehmungen in den Stirnenden der Holzstäbe vereinfacht. Es genügt in diesem Fall ein entsprechender Profilfräser, den man quer durch die Stirnenden der Holzstäbe laufen läßt.If, according to yet another embodiment of the invention, each holding member consists of an extruded part with a sawtooth-shaped or the like profile or contains one, the elaboration of the corresponding wedge-shaped recesses in the ends of the wooden bars is simplified. In this case, it is sufficient to use a corresponding profile cutter, which is run across the ends of the wooden bars.

Wenn nach noch einer weiteren Ausbildung der Erfindung das Halteglied an seinem vom Sägezahn rofil abgewendeten Abschnitt eine axiale Nut mit T-förmigem lichten Querschnitt zur Aufnahme eines oder mehrerer Gewindebolzen aufweist, die seitlich durch z.B. Stifte arretiert sind, wird vorteilhaft ein einstückiges Halteglied für den oder die Gewindebolzen erreicht, das sehr kurze Anschlußlängen zuläßt. Außerdem kann ein solches Halteglied wahlweise einen oder mehrere Gewindebolzen zur Ausführung entsprechender Mehrfachanschlüsse aufnehmen.If, according to yet another embodiment of the invention, the holding member has on its section facing away from the sawtooth profile an axial groove with a T-shaped clear cross section for receiving one or more threaded bolts which are laterally separated by e.g. Pins are locked, a one-piece holding member for the threaded bolt or bolts is advantageously achieved, which allows very short connection lengths. In addition, such a holding member can optionally receive one or more threaded bolts for the execution of corresponding multiple connections.

Nach noch einer weiteren Variante der Erfindung kann das Sägezahnprofil an einer auf der Stirnseite des Holzstabes aufliegenden Platte angeformt sein, an deren Außenseite ein oder mehrere Hohlkegelstücke oder dgl. zur Halterung des bzw. der Gewindebolzen befestigt sein können.According to yet another variant of the invention, the sawtooth profile can be formed on a plate resting on the end face of the wooden rod, on the outside of which one or more hollow cone pieces or the like can be fastened for holding the threaded bolt or bolts.

Noch eine andere Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß jedes Halteglied aus einem Strangpreßteil mit stern- oder speichenradförmigem Querschnittsprofil besteht. In dem zentralen Teil des Haltegliedes mit dem stern- oder speichenradförmigen Querschnittsprofil wird vorteilhaft der Gewindebolzen gehalten und die äußere Stirnseite dieses zentralen Teils bildet zweckmäßig die Auflagefläche für eine mit dem Gewindebolzen drehfest, jedoch axial verschieblich verbundene Treibmuffe. Diese Version der Erfindung ermöglicht eine extrem kurze Anschlußlänge, die praktisch nur noch der Länge einer Treibmuffe entspricht.Yet another embodiment of the invention is characterized in that each holding member consists of an extruded part with a star-shaped or spoke wheel-shaped cross-sectional profile. The threaded bolt is advantageously held in the central part of the holding member with the star-shaped or spoke wheel-shaped cross-sectional profile, and the outer end face of this central part expediently forms the bearing surface for a drive sleeve which is connected to the threaded bolt in a rotationally fixed but axially displaceable manner. This version of the invention enables an extremely short connection length, which practically only corresponds to the length of a drive sleeve.

Eine für relativ geringere Belastungen bestimmte, vereinfachte Version der Erfindung besteht darin, daß die Halteglieder für die Gewindebolzen aus Hülsen mit entsprechender Gewindebohrung bestehen. Auch in diesem Fall kann man extrem kurze Anschlußlängen erreichen. Der Durchmesser dieser Hülsen wird zur Schaffung ausreichender Klebeflächen entsprechend groß bemessen.A simplified version of the invention intended for relatively low loads consists in that the holding members for the threaded bolts consist of sleeves with a corresponding threaded bore. In this case too, extremely short connection lengths can be achieved. The diameter of these sleeves is appropriately large to create sufficient adhesive surfaces.

In Fig. 1 ist mit 10 ein Knotenstück einer Knotenpunktverbindung in einem Raumfachwerk bezeichnet, bei dem Holzstäbe 13 verwendet werden. Das aus Metall, z.B. Stahl hergestellte Knotenstück 10 weist mehrere sich in seinem Mittelpunkt schneidende Gewindebohrungen 11 auf, die zur Aufnahme von Gewindebolzen 12 bestimmt sind . An dem Knotenstück 10 sind lediglich beispielhaft zwei Vierkant-Holzstäbe 13 angeschlossen, die an ihren Enden Halteglieder 14 für jeweils einen Gewindebolzen 12 aufweisen.In Fig. 1, 10 denotes a node of a node connection in a space framework in which wooden rods 13 are used. The metal, e.g. Steel-made node piece 10 has a plurality of threaded bores 11 intersecting at its center, which are intended for receiving threaded bolts 12. Two square wooden rods 13 are connected to the node piece 10 merely by way of example, and have holding members 14 for a threaded bolt 12 at each end.

Die Halteglieder 14 bestehen beim Ausführungsbeispiel nach den Figuren 1 - 3 aus von einem Strangpreßprofil aus z.B. Aluminium abgetrennten Teilen, deren Länge in Abhängigkeit von der Kantenlänge der Holzstäbe 13 bemessen wird. Die Halteglieder 14 weisen an ihrem der Befestigung dienenden Abschnitt ein sägezahnförmiges Profil 15 auf, das in diesem Profil angepaßten axialen keilförmigen Ausnehmungen 16 im Stirnende der Holzstäbe 13 eingeklebt ist. Als Kleber kann hierfür ein im Handel erhältlicher Spezialkleber für Holz und Metall verwendet werden. Die Ausnehmungen 16 sind vorzugsweise durchgehend von einer Seite zur gegenüberliegenden Seite ausgebildet, z.B. unter Verwendung eines entsprechenden Formfräsers. Dadurch sind sie seitlich offen, was den Vorteil hat, daß dort überschüssiger Kleber austreten kann.In the exemplary embodiment according to FIGS. 1-3, the holding members 14 consist of parts separated from an extruded profile made of, for example, aluminum, the length of which is dimensioned as a function of the edge length of the wooden rods 13. The holding members 14 have on their section serving for fastening a sawtooth-shaped profile 15 which is glued into this profile adapted axial wedge-shaped recesses 16 in the front end of the wooden rods 13. A commercially available special adhesive for wood and metal can be used as an adhesive for this. The recesses 16 are preferably formed continuously from one side to the opposite side, for example using a corresponding form cutter. As a result, they are open on the side, which has the advantage that excess adhesive can escape there.

Die Halteglieder 14 weisen ferner an ihrem aus dem Stirnende jedes Holzstabs 13 hervorstehenden Abschnitt eine T-förmige Längsnut 17 auf, in welche der Gewindebolzen 12 mit seinem Kopf 18 eingesteckt und durch zwei querverlaufend angeordnete Stifte 19 in der in Fig. 2 gezeigten zentralen Position gesichert ist.The holding members 14 also have a T-shaped longitudinal groove 17 on their section protruding from the front end of each wooden rod 13, into which the threaded bolt 12 is inserted with its head 18 and secured by two transversely arranged pins 19 in the central position shown in FIG. 2 is.

Zum Eindrehen der Gewindebolzen 12 in die Gewindebohrungen 11 des Knotenstückes 10 dient jeweils eine Treibmuffe 20. Jede Treibmuffe 20 ist mit ihrem Gewindebolzen 12 durch einen Stift 21 drehfest verbunden, welcher im Gewindebolzen 12 fest verankert ist und sich in ein Langloch 22 der Treibmuffe (Schlüsselmuffe) erstreckt. Diese Treibmuffenanordnung ist bekannt und bedarf daher keiner weiteren Erläuterung. Bei fertiggestellter Verbindung liegt die Treibmuffe 20 mit einer Stirnseite auf einem abgeflachten Teil des Knotenstücks 10 und mit ihrer gegenüberliegenden Stirnseite auf den Flächen 23 zu beiden Seiten der Nut 17 mit T-förmigem lichten Querschnitt auf.A driving sleeve 20 is used to screw the threaded bolts 12 into the threaded bores 11 of the node piece 10. Each driving sleeve 20 is rotatably connected to its threaded bolt 12 by a pin 21, which is firmly anchored in the threaded bolt 12 and is inserted into an elongated hole 22 of the driving sleeve (key sleeve ) extends. This driving sleeve arrangement is known and therefore requires no further explanation. When the connection is completed, the driving sleeve 20 rests with an end face on a flattened part of the node piece 10 and with its opposite end face on the surfaces 23 on both sides of the groove 17 with a T-shaped clear cross section.

In Fig. 3 ist angedeutet, daß das Halteglied 14 auch zwei Gewindebolzen 12' (bei größerer Länge auch mehr als zwei Gewindebolzen) aufnehmen kann. Auch in diesem Fall sind die Gewindebolzen 12' gegen ein seitliches Heraustreten aus der Nut 17 durch querverlaufende Stifte 19 gesichert. Bei der Ausführungsform nach den Figuren 4 und 5 ist an dem Knotenstück 10 beispielhaft nur ein Vierkant-Holzstab 13 angeschlossen. Das Halteglied 14a für den Gewindebolzen 12 besteht bei dieser Auisführungsform aus einem Aluminium-Strangpreßteil 24, welches an der Unterseite, gleich der Ausführungsform nach den Figuren 1 - 3 ein sägezahnförmiges Profil 15 aufweist, das in entsprechende axiale keilförmige Ausnehmungen 16 eingeklebt ist. An der außenliegenden Seite des Teils 24 ist ein Hohlkegelstück 25 aus Aluminium angeschweißt, in welchem der Gewindebolzen 12 mit seinem Kopf 18 gehalten ist.In Fig. 3 it is indicated that the holding member 14 can also receive two threaded bolts 12 '(in the case of greater lengths also more than two threaded bolts). In this case too, the threaded bolts 12 'are secured against lateral emergence from the groove 17 by transverse pins 19. In the embodiment according to FIGS. 4 and 5, only a square wooden rod 13 is connected to the node piece 10 as an example. In this embodiment, the holding member 14a for the threaded bolt 12 consists of an aluminum extrusion 24, which on the underside, like the embodiment according to FIGS. 1-3, has a sawtooth-shaped profile 15 which fits into corresponding axial wedges shaped recesses 16 is glued. On the outer side of the part 24, a hollow cone piece 25 made of aluminum is welded, in which the threaded bolt 12 is held with its head 18.

Die Ausführungsform nach den Figuren 6 - 9 enthält ein Halteglied 14b für einen Gewindebolzen 26 mit einem speichenradförmigen Querschnitt, wobei in dem zentralen oder nabenförmigen Teil 27 eine Gewindebohrung 28 für den Gewindebolzen 26 vorgesehen ist. Das Halteglied 14b wird ebenfalls vorzugsweise als Strangpreßteil aus Aluminium hergestellt, und die einzelnen Halteglieder werden von dem Strangpreßprofil mit einer solchen Länge abgetrennt, daß eine ausreichend große Klebefläche erreicht wird.The embodiment according to FIGS. 6-9 contains a holding member 14b for a threaded bolt 26 with a spoke wheel-shaped cross section, a threaded bore 28 for the threaded bolt 26 being provided in the central or hub-shaped part 27. The holding member 14b is also preferably produced as an extruded part made of aluminum, and the individual holding members are separated from the extruded profile with a length such that a sufficiently large adhesive surface is achieved.

Der Gewindebolzen 26 ist bei diesem Ausführungsbeispiel als Differenz-Gewindebolzen ausgebildet, der bei Knotenpunktverbindungen von Raumfachwerken bekannt ist und somit keiner weiteren Erläuterung bedarf. Die drehfeste, jedoch eine axiale Relativbewegung zulassende Verbindung zwischen dem Gewindebolzen 26 und der Treibmuffe 20 entspricht dem Ausführungsbeispiel nach den Figuren 1 und 4.In this exemplary embodiment, the threaded bolt 26 is designed as a differential threaded bolt, which is known in the case of junction connections of space frameworks and therefore does not require any further explanation. The connection between the threaded bolt 26 and the drive sleeve 20, which is non-rotatable but permits an axial relative movement, corresponds to the exemplary embodiment according to FIGS. 1 and 4.

Die Befestigung des Haltegliedes 14b in den Enden des Vierkant-Holzstabes 13 erfolgt durch Einklebung in entspr hende Ausnehmungen. Im einzelnen ist zu diesem Zweck in jedem Stirnende des Vierkant-Holzstabes 13 eine zentrale axiale Bohrung 29 vorgesehen, von der radial nach außen Schlitze 30 verlaufen. Koaxial zur Bohrung 29 ist eine kreisringförmige Ausnehmung 31 vorgesehen. Die Bohrung 29, Schlitze 30 sowie die Ausnehmung 31 sind sämtlich auf eine Tiefe ausgearbeitet, die etwa der Länge des Halteglieds 14b entspricht (vergl. Fig. 6). Andererseits sind der Durchmesser der Bohrung 29 und die Breite der Schlitze 30 sowie der ringförmigen Ausnehmung 31 derart bemessen, daß bei eingesetztem Halteglied 14b seitliche Zwischenräume (Fig. 7) verbleiben, die der Aufnahme von Klebstoffen dienen. Der zentrale oder nabenförmige Teil 27 des Halteglieds 14b wird von der Bohrung 29 aufgenommen, während die Speichen 32 in den Schlitzen 30 sitzen. Der felgenförmige Außenumfangsabschnitt 33 des Halteglieds 14b findet Platz in der ringförmigen Ausnehmung 31. Fig. 7 zeigt, daß die zwischen dem eingesetzten Halteglied 14b und der Bohrung 29, den Schlitzen 30 und der ringförmigen Ausnehmung 31 verbleibenden Zwischenräume durch einen Füllkleber 34 bzw. Spezial-Kleber 35 ausgefüllt sind. Diese Kleber sind im Handel erhältlich. Da die Schlitze 30 seitlich nach außen offen sind, kann beim Einbau des Halteglieds 14b überschüssiger Klebstoff vorteilhaft seitlich abgedrängt werden.The fastening of the holding member 14b in the ends of the square wooden rod 13 is carried out by gluing into corresponding recesses. For this purpose, a central axial bore 29 is provided in each end of the square wooden rod 13, from which slots 30 extend radially outward. An annular recess 31 is provided coaxially with the bore 29. The bore 29, slots 30 and the recess 31 are all worked out to a depth which corresponds approximately to the length of the holding member 14b (see FIG. 6). On the other hand, the diameter of the bore 29 and the width of the slots 30 and the annular recess 31 are dimensioned such that lateral spaces are present when the holding member 14b is inserted (Fig. 7) remain, which are used to hold adhesives. The central or hub-shaped part 27 of the holding member 14b is received by the bore 29, while the spokes 32 sit in the slots 30. The rim-shaped outer circumferential section 33 of the holding member 14b is accommodated in the annular recess 31. FIG. 7 shows that the gaps remaining between the inserted holding member 14b and the bore 29, the slots 30 and the annular recess 31 by a filler adhesive 34 or special Glue 35 are filled. These adhesives are commercially available. Since the slots 30 are laterally open to the outside, excess adhesive can advantageously be forced to the side when the holding member 14b is installed.

In den Figuren 10 und 11 ist ein Halteglied 14c mit sternförmigem Querschnitt für den Gewindebolzen 26 gezeigt. Im einzelnen weist dieses Halteglied einen zentralen Teil 36 mit einer Gewindebohrung 37 zur Aufnahme des Gewindebolzens 26 auf. Von dem zentralen Teil 36 verlaufen radial nach außen gleichförmige Stege 38. Das Halteglied 14c besteht gleichfalls vorzugsweise aus einem Aluminium-Strangpreßteil, das in vorbestimmten Längen von einem Strangpreßprofil abgetrennt wird. Die Einklebung dieses Halteglieds erfolgt ähnlich wie beim Ausführungsbeispiel nach den Figuren 6 - 9 in einer Axialbohrung 29 in den Stirnenden des Vierkant-Holzstabes 13, von der radial nach außen Schlitze 30 verlaufen. Der zentrale Teil 36 des Halteglieds 14c wird wieder von der Axialbohrung 29 aufgenommen, während die Stege 38 in den Schlitzen 30 sitzen. Zwischen dem Halteglied 14c und der Bohrung 29 bzw. den Schlitzen 30 ist wie beim vorangegangenen Ausführungsbeispiel genügend Zwischenraum zur Aufnahme eines geeigneten Spezial-Klebers 35 bzw. Füllklebers 34 vorhanden, wie Fig. 10 zeigt.FIGS. 10 and 11 show a holding member 14c with a star-shaped cross section for the threaded bolt 26. In detail, this holding member has a central part 36 with a threaded bore 37 for receiving the threaded bolt 26. Uniform webs 38 extend radially outward from the central part 36. The holding member 14c likewise preferably consists of an aluminum extrusion which is separated from an extrusion profile in predetermined lengths. This holding member is glued in a manner similar to the exemplary embodiment according to FIGS. 6-9 in an axial bore 29 in the front ends of the square wooden rod 13, from which slots 30 run radially outwards. The central part 36 of the holding member 14c is again received by the axial bore 29, while the webs 38 are seated in the slots 30. As in the previous exemplary embodiment, there is sufficient space between the holding member 14c and the bore 29 or the slots 30 for receiving a suitable special adhesive 35 or filler adhesive 34, as shown in FIG. 10.

Beim Ausführungsbeispiel nach den Figuren 12 und 13 besteht das Halteglied 14d für den Gewindebolzen 26 aus einer einfachen Hülse aus z.B. Aluminium mit einer entsprechenden Gewindebohrung 39. Der Durchmesser dieser Hülse ist kleiner als derjenige der Zentralbohrung 29 in den Stirnenden des Vierkant-Holzstabes 13, um beim Einkleben des Halteglieds 14d genügend Zwischenraum für die Unterbringung des Spezial-Klebers 35 zu erhalten. Ferner ist der Durchmesser des Halteglieds 14d so gewählt, daß eine ausreichend große Klebefläche zur Verfügung steht.In the embodiment according to Figures 12 and 13, the holding member 14d for the threaded bolt 26 consists of a simple sleeve made of e.g. Aluminum with a corresponding threaded bore 39. The diameter of this sleeve is smaller than that of the central bore 29 in the front ends of the square wooden rod 13 in order to obtain sufficient space for the special adhesive 35 when the holding member 14d is glued in. Furthermore, the diameter of the holding member 14d is selected so that a sufficiently large adhesive surface is available.
