Die Erfindung betrifft ein Fachwerk mit mehreren zueinander parallelen, gegeneinander abgestützten, ebenen Gitterrahmen, die aus im Dreiecksverband angeordneten Streben gleicher Länge aufgebaut sind, welche mit abgeflachten, gezahnten Enden in entsprechend gezahnte Nuten am Umfang von zylindrischen, mit ihrer Achse senkrecht zur Fachwerkebene liegenden Verbindungsstücken passend eingreifen.The invention relates to a framework with several mutually parallel, mutually supported, flat lattice frames made up of triangular braces of equal length, which with flattened, toothed ends in correspondingly toothed grooves on the circumference of cylindrical, engage with their axis perpendicular to the truss level connecting pieces.

Bei einem derartigen bekannten Fachwerk sind die parallelen Gitterrahmen gegeneinander durch Streben abgestützt, deren Enden an den Stirnseiten der Verbindungsstücke mittels Schrauben befestigt sind. Der Zusammenbau eines solchen Fachwerks und das Auswechseln einzelner Streben sind schwierig und zeitraubend. In such a known framework, the parallel lattice frames are against each other by struts supported, the ends of which are attached to the end faces of the connecting pieces by means of screws. Of the Assembling such a framework and replacing individual struts are difficult and time-consuming.

Der Erfindung liegt die Aufgabe zugrunde, unter Beibehaltung des bekannten Konstruktionsprinzips ein Fachwerk zu schaffen, das in einfacher Weise spannungsfrei zusammengebaut werden kann und bei dem einzelne Streben ohne Schwierigkeiten ausgewechselt werden können.The invention is based on the object while maintaining the known construction principle to create a framework that can be easily assembled without stress and with the individual struts can be exchanged without difficulty.

Die Erfindung löst diese Aufgabe dadurch, daß die Gitterrahmen deckungsgleich angeordnet sind und die Abstützung durch die Verbindungsstücke, die mindestens eine dem Abstand der äußeren Gitterrahmen entsprechende Länge aufweisen, erfolgt.The invention solves this problem in that the lattice frames are arranged congruently and the Supported by the connecting pieces, which are at least one the distance between the outer lattice frame have appropriate length takes place.

Nach einem weiteren Merkmal der Erfindung sind die Strebenenden in den Verbindungsstücken in deren Längsrichtung, vorzugsweise durch Reibungsschluß, festgelegt.According to a further feature of the invention, the strut ends are in the connecting pieces in their Longitudinal direction, preferably set by frictional engagement.

Die Erfindung wird nachfolgend an Hand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. Es zeigtThe invention is described below with reference to the exemplary embodiments shown in the drawing described in more detail. It shows

Setzt man Streben 12 zwischen die Verbindungsstücke F1 ein, erhält man eine Serie von Dreiecken C. Die Streben 11 sind beiden Dreiecken B und C gemeinsam. If struts 12 are inserted between the connecting pieces F 1 , a series of triangles C is obtained. The struts 11 are common to both triangles B and C.

Von den Verbindungsstücken F1 erstrecken sich zueinander im Winkel angeordnete Streben 13 nachStruts 13 arranged at an angle to one another extend from the connecting pieces F 1

as oben, an deren oberen Enden Verbindungsstücke F2 sitzen, so daß Dreiecke D gebildet werden. Zwischen die Verbindungsstücke F2 sind Streben 14 eingesetzt, wodurch eine weitere Serie von Dreiecken E gebildet wird. Dadurch, daß diese Dreiecke aufeinander aufgebaut werden, erhält man eine einheitliche Gitterrahmenkonstruktion. Diese Dreiecke sind gleichseitig, so daß die einzelnen Streben ausgetauscht werden können.as above, at the upper ends of which sit connecting pieces F 2 , so that triangles D are formed. Struts 14 are inserted between the connecting pieces F 2 , as a result of which a further series of triangles E is formed. Because these triangles are built on top of each other, a uniform lattice frame construction is obtained. These triangles are equilateral so that the individual struts can be exchanged.

Die Verbindungsstücke F, F1, F2 sind gleich ausgebildet, so daß hier nur eines, nämlich F1, beschrieben wird. Das Verbindungsstück F1 besteht vorzugsweise aus einer zylindrischen Stange von gewünschtem Druchmesser und Länge. Am Umfang des Verbindungsstücks ist eine Mehrzahl von radial angeordneten Nuten 15 vorgesehen, von denen sich jede in Längsrichtung von einem Ende des Verbindungsstücks zum anderen erstreckt. Wie aus Fig. 4 ersichtlich, liegen die Nuten einander genau gegenüber. Die Seitenwände 16 der Nuten 15 laufen nach der Mitte des Verbindungsstücks konisch zu und weisen mehrere sich längs erstreckende Ausnehmungen 17 und dazwsichenliegende Rippen 18 auf.The connecting pieces F, F 1 , F 2 are of the same design, so that only one, namely F 1 , is described here. The connecting piece F 1 preferably consists of a cylindrical rod of the desired diameter and length. A plurality of radially arranged grooves 15 are provided on the circumference of the connecting piece, each of which extends in the longitudinal direction from one end of the connecting piece to the other. As can be seen from Fig. 4, the grooves are exactly opposite one another. The side walls 16 of the grooves 15 taper conically towards the center of the connecting piece and have several longitudinally extending recesses 17 and ribs 18 lying between them.

Mehrere Streben 11, 12 und 13 (Fig. 1) greifen in das Verbindungsstück F1 ein und gehen radial vonSeveral struts 11, 12 and 13 (Fig. 1) engage in the connecting piece F 1 and go radially from

diesem aus. Jede dieser Streben ist an beiden Enden 19 abgeflacht und mit Rippen 20 und Ausnehmungenthis off. Each of these struts is flattened at both ends 19 and with ribs 20 and recesses

" 21 versehen. Diese abgeflachten Enden werden in die"21. These flattened ends are inserted into the

Nuten 15 mit den Seitenkanten eingeführt und dann so eingetrieben, daß die Rippen 20 und Ausnehmungen 21 der abgeflachten Enden mit den Ausnehmungen 17 und Rippen 18 in den Seitenwänden 16 der Nuten greifen.Grooves 15 introduced with the side edges and then driven in so that the ribs 20 and recesses 21 of the flattened ends with the recesses 17 and ribs 18 in the side walls 16 of the Grip grooves.

Die abgeflachten Enden 19 der Streben sind ausgerichtet und liegen in der gleichen axialen Längsebene der Streben. Die von dem Verbindungsstück F1 entfernt liegenden, abgeflachten Enden 19 der Streben greifen in Nuten der gleich ausgebildeten benachbarten Verbindungsstücke (Fig. 1). Da das Verbindungsstück F1 mit sechs Nuten dargestellt ist, muß der Gitterrahmen um das Verbindungsstück herum aus sechs gleichseitigen Dreiecken bestehen.The flattened ends 19 of the struts are aligned and lie in the same axial longitudinal plane of the struts. The flattened ends 19 of the struts located at a distance from the connecting piece F 1 engage in grooves in the identically designed adjacent connecting pieces (FIG. 1). Since the connecting piece F 1 is shown with six grooves, the lattice frame must consist of six equilateral triangles around the connecting piece.

Die Verbindungsstücke einer horizontalen Reihe des Gitterrahmens sind zu den Verbindungsstücken einer anschließenden Reihe versetzt angeordnet, ebenso wie die Verbindungsstücke einer vertikalen Reihe versetzt zu den Verbindungsstücken einer anschließenden vertikalen Reihe angeordnet sind. Die so aufgebauten Gitterrahmen richten sich von selbst aus, und ein Verziehen bzw. Verwerfen wird verhindert.The connectors of a horizontal row of the lattice frame are to the connectors a subsequent row arranged offset, as well as the connecting pieces of a vertical row are arranged offset to the connecting pieces of a subsequent vertical row. The so constructed Lattice frames align themselves and warping or warping is prevented.

Aus F i g. 4 und 5 ist ersichtlich, daß die Endkanten der abgeflachten Enden 19 der Streben im rechten Winkel zur Strebenlänge stehen und am Boden der Nut 15 anliegen, so daß bei irgendeiner anders als parallel zum Gitterrahmen wirkenden Kraft diese Endkanten fest gegen den Boden der Nut anliegen und jedem Verziehen entgegenwirken.From Fig. 4 and 5 it can be seen that the end edges of the flattened ends 19 of the struts in the right Stand angle to the strut length and abut the bottom of the groove 15, so that any other than force acting parallel to the lattice frame, these end edges rest firmly against the bottom of the groove and counteract any warping.

Beim Aufbau eines Fachwerks aus zwei Gitterrahmen, wie in F i g. 2 gezeigt, werden die Gitterrahmen A und G in der oben beschriebenen Weise zusammengefügt und parallel im Abstand zueinander angeordnet. Die Verbindungsstücke F, F1 usw. sind so lang wie der Abstand der äußeren Begrenzungsebenen der beiden Gitterrahmen A und G, wobei ihre Stirnenden in den äußeren Begrenzungsebenen der Gitterrahmen A und G liegen.When building a framework from two lattice frames, as shown in FIG. As shown in Fig. 2, the lattice frames A and G are assembled in the manner described above and spaced apart in parallel. The connecting pieces F, F 1 etc. are as long as the distance between the outer boundary planes of the two lattice frames A and G, their front ends being in the outer boundary planes of the lattice frames A and G.

Ein auf eine Strebe ausgeübter axialer Zug überträgt sich auf die mit der Strebe zusammenwirkenden Verbindungsstücke und damit wieder auf die anderen um dieses Verbindungsstück angeordneten Streben, so daß alle diese Streben dem axialen Zug einen gemeinsamen Widerstand entgegensetzen. Da auch jeder Gitterrahmen gegen Verwerfen widerstandsfähig ist, weist das fertige Fachwerk eine große Festigkeit und Steifheit auf.An axial tension exerted on a strut is transmitted to those interacting with the strut Connecting pieces and thus again on the other struts arranged around this connecting piece, so that all these struts oppose a common resistance to the axial pull. There too Every lattice frame is resistant to warping, the finished truss shows great strength and stiffness.

Soll ein Fachwerk mit drei Gitterrahmen erstellt werden, so sind die Gitterrahmen A, G und H wie in Fig. 3 gezeigt anzuordnen. Um den Gitterrahmen G leichter in seiner Mittelstellung anbringen zu können, sind die Verbindungsstücke F, F1 usw. zwischen ihren Enden bei ζ gekennzeichnet. Die Länge der Verbindungsstücke hängt von der Dicke der Fachwerkkonstruktion ab, wobei die Gitterrahmen A und H an den Enden und der Gitterrahmen G an dem vorher festgelegten Platz anzubringen sind. Die Errichtung des Gitterrahmens G an der gewünschten Stelle verursacht keine Schwierigkeiten, da das Zusammenfügen der verschiedenen Streben ebenso erfolgt wie bei der vorbeschriebenen Konstruktion des Gitterrahmens A. Die drei Gitterrahmen A, G und H werden in ihrer Stellung zueinander durch die Verbindungsstücke F, F1 usw. gehalten, die sie fest miteinander verbinden.If a framework with three lattice frames is to be created, the lattice frames A, G and H are to be arranged as shown in FIG. 3. In order to be able to attach the grid frame G more easily in its central position, the connecting pieces F, F 1 etc. are marked between their ends at ζ . The length of the connecting pieces depends on the thickness of the truss structure, with the lattice frames A and H being attached to the ends and the lattice frame G at the predetermined location. The construction of the space frame G in the desired position does not cause any difficulties, since the joining of the different struts also carried out as in the above-described construction of the space frame A. The three grid frame A, G and H are in their position to one another by the connecting pieces F, F 1 etc. that firmly connect them together.

Wenn ein Aufbau an einem abgelegenen Ort erfolgen soll, können die Einzelteile, besonders die Streben und Verbindungsstücke, an Ort und Stelle gebracht werden. Da die Streben und Verbindungsstücke aus gezogenem Metall hergestellt werden können, sind kleine Toleranzen einzuhalten.If an assembly is to be done in a remote location, the individual parts, especially the struts and connectors, put in place. As the struts and connectors can be made from drawn metal, small tolerances must be observed.

Zum Zusammenfügen eines Gitterrahmens ist es nur nötig, die abgeflachten Enden 19 mit den Kanten in die Nuten 15 einzuführen und mit einem Hammer hineinzutreiben, bis die äußeren Kanten 24 der abgeflachten Enden 19 mit den Enden der Verbindungsstücke F und F1 usw. abschließen oder bis die äußere Kante 24 die mit ζ markierte Stellung auf dem Verbindungsstück erreicht.To assemble a lattice frame, it is only necessary to insert the flattened ends 19 with the edges into the grooves 15 and drive them in with a hammer until the outer edges 24 of the flattened ends 19 are flush with the ends of the connecting pieces F and F 1 etc. or up to the outer edge 24 reaches the position marked with ζ on the connector.

Da die Größe der Verbindungsstücke und Durchmesser und die Länge der Rohrstreben genormt sind, führt das Zusammenfügen von flachen Streben und Verbindungsstücken zu keinen Spannungen in der Wandkonstruktion. Die Dreiecke des Gitterrahmens können aus Stangen od. dgl. jedes gewünschten Querschnitts gebildet werden. Solche Konstruktionen brauchen nur teilweise mit gelernten Arbeitern errichtet zu werden, so daß die Montagekosten niedrig gehalten werden können.Since the size of the connecting pieces and the diameter and the length of the pipe struts are standardized, the joining of flat struts and connecting pieces does not lead to any tension in the Wall construction. The triangles of the lattice frame can be made of rods or the like of any desired cross-section are formed. Such constructions need only partially built with skilled workers so that the assembly cost can be kept low.
