Description

  

  Bauelement     für    zerlegbare     Fachwerkkonstruktionen       Die Erfindung betrifft ein Bauelement für zer  legbare     Fachwerkkonstruktionen,    bei denen Kupp  lungsvorrichtungen verwendet werden, die je einen  Gewindebolzen und eine denselben umgebende Schlüs  selmuffe aufweisen. Als derartige Bauelemente wur  den bisher Stäbe oder Rohre verwendet, die an bei  den Enden mit derartigen Kupplungsvorrichtungen  versehen. waren, sowie Knotenstücke, die mit einer  Mehrzahl von Gewindebohrungen versehen waren.  



  Wenn man nun diese bekannten Bauelemente  verwendet, so ergibt sich der Nachteil, dass schon  für die Zusammensetzung relativ einfacher Fach  werkkonstruktionen sehr zahlreiche Bauelemente be  nötigt wurden und dass das Zusammensetzen in  folgedessen einen erheblichen Zeitaufwand bean  sprucht. Zur Vermeidung dieses Nachteiles zeichnet  sich das Bauelement nach der Erfindung dadurch  aus, dass es einen starren Rahmen aufweist, der     mit     mehr als zwei solcher Kupplungsvorrichtungen selbst  versehen ist.  



  Es ist klar, dass man dieses Bauelement über die  Kupplungsvorrichtungen mit anderen Bauelementen  zusammensetzen kann, die     mit    entsprechenden  Kupplungen oder Gewindebohrungen versehen sind,  z. B. mit anderen rahmenförmigen Bauelementen  oder mit den bekannten Stäben, Rohren oder Kno  tenstücken.  



  In der Zeichnung sind zwei Ausführungsbei  spiele des Erfindungsgegenstandes dargestellt. Es ist:       Fig.    1 eine Draufsicht auf ein erstes Bauelement;       Fig.2    eine Kupplungsvorrichtung in grösserem       Massstabe;          Fig.    3 eine Draufsicht auf zwei miteinander     ge-          kuppelte    Bauelemente und       Fig.    4 eine perspektivische Darstellung der Bau  elemente nach     Fig.    3 in grösserem     Massstabe.     



  Das Bauelement nach     Fig.    1 ist ein aus Rohren    9-11 zusammengeschweisster, rechteckiger Fach  werkrahmen. Die zueinander parallelen Längsrohre 9  und 10 sind durch fünf     Querrohre    11 starr     mitein-          ander    verbunden. Die Längsrohre 9 und 10 sind an  ihren Enden 4 mit Öffnungen versehen, zum An  schluss je einer Kupplungsvorrichtung 5.  



  Die Kupplungsvorrichtung 5 ist an sich bekann  ter Art und weist gemäss     Fig.    2 eine     Schlüssehnuffe     5a auf, die mit einem Längsschlitz 5b versehen ist,  in den ein Querstift 5c hineinragt, der an einem in  die erwähnte Öffnung passenden Gewindebolzen 5d  angebracht ist, der in     Fig.    2 nur durch den Längs  schlitz 5b sichtbar ist.

   An einem Rohr 1 sind meh  rere Querstutzen 3 vorgesehen, die ebenfalls je mit  einer Gewindebohrung versehen sind, und es ist er  sichtlich, dass durch Drehen der Schlüsselmuffe     5a     der     Gewindebolzen    5d teilweise aus dem Rohrende 4  heraus und in einen Querstutzen 3     hineingeschraubt     werden kann, um das Bauelement, zu dem das Rohr  ende 4 gehört, an ein anderes Bauelement anzu  schliessen, welches Bauelement zum Beispiel das in       Fig.    1 gezeigte Ausführungsbeispiel oder ein anderes  Rohr sein kann.  



  In     Fig.    1 ist gezeigt, wie das rahmenförmige  Bauelement mit drei Kupplungsvorrichtungen 5 an  drei     polyedrische        Knotenstücke    12 angeschlossen ist,  von denen eines über eine weitere Kupplungsvorrich  tung 5 mit einem Rohr 13 verbunden ist. Das Rohr  13 weist wieder einen Querstutzen 3 auf, der über  eine weitere Kupplungsvorrichtung 5 mit dem     rah-          menförmigen    Bauelement verbunden ist.  



  Es ist hervorzuheben, dass nach     Fig.    1 die Kupp  lungsvorrichtungen 5 und somit die entsprechenden  Öffnungen in den Enden der Rohre 9 paarweise,  nämlich zwei rechts und zwei links, angeordnet sind,  wobei die Achsen der Gewinde jedes Gewindepaares  zueinander parallel sind.     Hierdurch    wird gewährlei-      stet, dass,     wennn    der     Fachwerkrahmen    9-11 in der  Zeichenebene auf Biegung oder auf Drehung bean  sprucht wird, die eine Kupplungsvorrichtung jedes  Paares auf Zug und die andere Kupplungsvorrich  tung auf Druck     beansprucht        wird.    Anstelle von Roh  ren 9-l1 könnten auch Profilstäbe verwendet wer  den.  



  In     Fig.    3 und 4 sind zwei Bauelemente gezeigt,  die je einen rechteckigen starren Rahmen aufweisen,  der aus     zwei    Längsschienen<B>101</B> und     zwei    Quer  schienen 102 von     U-förmigem    Profil zusammenge  setzt ist, die über Knotenbleche 103 und Schrauben  106 (oder Nieten) fest miteinander verbunden sind.  In den Längsschienen 101 sind die Enden von Holz  platten 105 gefasst.

   Der Rahmen ist an jeder Quer  schiene 102 mit zwei zueinander parallelen Gewinde  bohrungen versehen, in welche die     Gewindebolzen     von zwei Kupplungsvorrichtungen 5 eingeschraubt  sind; die beiden Bauelemente, die je für sich bereits  eine Plattform bilden, sind durch zwei Schienen<B>108</B>  von U-förmigem Profil     zu    einer grösseren Plattform  fest miteinander verbunden. Die Schienen 108 weisen  Gewindebohrungen 109 für die Gewindebolzen der  Kupplungsvorrichtungen 5 auf. Die Schienen 108  sind an ihren Enden noch mit Gewindezapfen 110  versehen, auf die Knotenstücke 12 geschraubt sind,  von denen zwei über Kupplungsstücke 5 und ein Rohr  <B>107</B> miteinander verbunden sind.  



  Anstelle der     Holzplatten    105 könnte man natür  lich auch eine oder mehrere Blechplatten verwenden,  die gegebenenfalls auch     mit    dem Rahmen verschweisst  sein könnten. Durch die     Holz-    oder Blechplatten wird  das Bauelement nicht nur zu einer     Plattform    ausgebil  det, die zum Beispiel     im    Gerüstbau (Fachwerkbau)       vielfach    anwendbar ist, sondern es wird auch eine    bedeutende Versteifung des Rahmens erzielt. Die auf  die Platten 105 wirkenden Kräfte werden natürlich  über die Kupplungsvorrichtungen 5 auf die anderen  Bauelemente des Fachwerkes übertragen, die mit dem  Bauelement nach     Fig.    3 und 4 zusammengesetzt sind.  



  Im Falle von     Fig.    3 und 4 kann man nach Lösen  der Schrauben 106 die Holzplatten 105 ersetzen, da  der Eisenrahmen normalerweise länger brauchbar ist  als die Holzplatten. Das Bauelement wird aber beim  Zusammensetzen von     Fachwerkkonstruktionen    selbst  verständlich immer als Ganzes verwendet.



  Component for collapsible framework structures The invention relates to a component for decomposable framework structures, in which coupling devices are used, each having a threaded bolt and a key surrounding the same selmuffe. As such components were previously used rods or tubes, which are provided at the ends with such coupling devices. were, as well as knots that were provided with a plurality of threaded holes.



  If you now use these known components, there is the disadvantage that even for the composition of relatively simple truss structures very numerous components were required and that the assembly consequently requires a considerable amount of time bean. To avoid this disadvantage, the component according to the invention is characterized in that it has a rigid frame which is provided with more than two such coupling devices themselves.



  It is clear that this component can be put together via the coupling devices with other components that are provided with corresponding couplings or threaded holes, e.g. B. with other frame-shaped components or with the known rods, tubes or kno ten pieces.



  In the drawing, two Ausführungsbei are shown games of the subject invention. It is: FIG. 1 a plan view of a first component; 2 shows a coupling device on a larger scale; 3 shows a plan view of two components coupled to one another and FIG. 4 shows a perspective illustration of the construction elements according to FIG. 3 on a larger scale.



  The component according to FIG. 1 is a rectangular Fachwerkrahmen welded together from tubes 9-11. The longitudinal tubes 9 and 10, which are parallel to one another, are rigidly connected to one another by five transverse tubes 11. The longitudinal tubes 9 and 10 are provided with openings at their ends 4, for each connection to a coupling device 5.



  The coupling device 5 is known per se and, according to FIG. 2, has a key sleeve 5a which is provided with a longitudinal slot 5b into which a transverse pin 5c protrudes, which is attached to a threaded bolt 5d that fits into the aforementioned opening and is shown in Fig. 2 is visible only through the longitudinal slot 5b.

   On a pipe 1, several cross connectors 3 are provided, which are also each provided with a threaded hole, and it is clear that by turning the wrench socket 5a the threaded bolt 5d can be partially screwed out of the pipe end 4 and into a cross connector 3, in order to connect the component to which the pipe end 4 belongs to another component, which component can be, for example, the embodiment shown in FIG. 1 or another pipe.



  In Fig. 1 it is shown how the frame-shaped component with three coupling devices 5 is connected to three polyhedral junction pieces 12, one of which is connected to a pipe 13 via a further coupling device 5. The tube 13 again has a transverse connector 3, which is connected to the frame-shaped component via a further coupling device 5.



  It should be emphasized that according to FIG. 1, the coupling devices 5 and thus the corresponding openings in the ends of the tubes 9 are arranged in pairs, namely two on the right and two on the left, the axes of the threads of each thread pair being parallel to one another. This ensures that when the framework frame 9-11 is subjected to bending or rotation in the plane of the drawing, one coupling device of each pair is subjected to tension and the other coupling device is subjected to compression. Instead of pipes 9-l1, profile rods could also be used.



  In Fig. 3 and 4, two components are shown, each having a rectangular rigid frame, which is composed of two longitudinal rails <B> 101 </B> and two transverse rails 102 of U-shaped profile, which is via gusset plates 103 and Screws 106 (or rivets) are firmly connected to one another. In the longitudinal rails 101, the ends of wooden plates 105 are taken.

   The frame is provided on each cross rail 102 with two parallel threaded bores into which the threaded bolts of two coupling devices 5 are screwed; the two components, which each already form a platform by themselves, are firmly connected to one another by two rails 108 with a U-shaped profile to form a larger platform. The rails 108 have threaded bores 109 for the threaded bolts of the coupling devices 5. The rails 108 are also provided at their ends with threaded pins 110, onto which node pieces 12 are screwed, two of which are connected to one another via coupling pieces 5 and a tube 107.



  Instead of the wooden plates 105 one could of course also use one or more sheet metal plates, which could optionally also be welded to the frame. Through the wood or sheet metal panels, the component is not only ausgebil det to a platform, which can be used for example in scaffolding (half-timbered construction), but it is also a significant stiffening of the frame is achieved. The forces acting on the plates 105 are of course transmitted via the coupling devices 5 to the other structural elements of the framework which are assembled with the structural element according to FIGS. 3 and 4.



  In the case of FIGS. 3 and 4, after loosening the screws 106, the wooden panels 105 can be replaced, since the iron frame can normally be used longer than the wooden panels. The component is of course always used as a whole when assembling truss structures.
