Abstract

1. Tube/gusset plate connection as a disconnectable coupling element free from slip between a circular, square or rectangular hollow section and a gusset plate, characterized in that a jaw (3) is welded to the front end of said hollow section (1) by means of a single bevel groove weld, said jaw being provided with a wedge-shaped groove into which a wedge-shaped fishplate (2) welded to a gusset plate by means of a butt weld is slipped, a sleeve (4) being slipped into the end of said jaw and fixed by a spring (5), thus securing the position of said fishplate.

Description

Die Rohr-Knotenblech-Verbindung (RKV) dient als Kupplungselement für Stahl (und Aluminiumkonstruktionen) zwischen Hohlprofilen vor allem mit rundem, aber auch quadratischem oder rechteckigem Querschnitt und einem Knotenblech.The pipe-gusset plate connection (RKV) serves as a coupling element for steel (and aluminum structures) between hollow profiles, especially with a round, but also square or rectangular cross-section and a gusset plate.

Im allgemeinen werden derartige Anschlüsse

  • - Stab an Stab geschweißt:
    • Sie sind vornehmlich Werkstattfertigungen, wobei eine ganze Konstruktionseinheit, bestehend aus mehreren Stäben, in der Werkstatt hergestellt wird. Baustellenschweißungen werden fast nur bei großen Rohren durchgeführt.
    • Die Stabverbindungen sind nur durch Zerstörung zu lösen.
  • - Stab mit Stab verschraubt:
    • Hauptsächlich im Mastbau anzutreffen und dort zulässig. Die Gurtprofile sind durchlaufend ausgebildet, die Füllstäbe erhalten Beanspruchungen, die mit einer einschnittigen Schraube aufzunehmen sind.
  • - Stab mit Stab mit Einschaltung eines Knotenblechs verschraubt:
    • Es werden einfache oder doppelte Anschlußlaschen in die Rohre, die normalerweise geschlitzt werden müssen, eingeschweißt. Die einfache Lasche, die nur einschnittig auf die Schraube wirkt, erzeugt zusätzlich auf den Stab ein Moment aus Exzentrizität. Die Knotenbleche werden relativ groß und bilden einen großen Anteil am Konstruktionsgewicht (15-30%). Wenn normale Stahlbauschrauben verwendet werden, so stellt sich ein Schlupf wegen der Durchmesserdifferenz zwischen Schraubenloch und Schraube ein. Richtarbeiten sind teuer und kostenmäßig vorher schwer zu erfassen.
  • - Spezielle Stab-Knoten-Verbindungen:
    • Diese finden vornehmlich für Raumstrukturen Verwendung und werden firmenorientiert angewandt, das heißt, der Systemeigentümer führt auch die Herstellung der Konstruktion aus. Hierbei handelt es sich um Systemlösungen des Knotens mit dem Anschluß der Stäbe an diesen, das heißt, die Stabanschlüsse können nur für den speziellen Knoten verwendet werden.
In general, such connections
  • - Welded rod to rod:
    • They are primarily workshop productions, whereby an entire construction unit, consisting of several bars, is manufactured in the workshop. Site welding is almost only carried out on large pipes.
    • The rod connections can only be released by destruction.
  • - Bolted rod with rod:
    • Mainly found in mast construction and permitted there. The belt profiles are continuous, the filler rods are subjected to stresses that can be absorbed with a single-point screw.
  • - Bolted rod with rod with activation of a gusset plate:
    • Single or double connection lugs are welded into the pipes, which normally have to be slotted. The simple tab, which only acts on the screw in one section, also creates a moment of eccentricity on the rod. The gusset plates become relatively large and make up a large proportion of the construction weight (15-30%). If normal steel construction screws are used, slippage occurs due to the difference in diameter between screw hole and screw. Straightening work is expensive and difficult to record beforehand in terms of costs.
  • - Special rod-node connections:
    • These are primarily used for spatial structures and are used in a company-oriented manner, which means that the system owner also carries out the construction. These are system solutions of the node with the connection of the rods to it, which means that the rod connections can only be used for the special node.

Die hier vorgestellte Rohr-Knotenblech-Verbindung gemäß den Patentansprüchen bietet einen breiten Raum der Anwendung und einige Merkmale, die zur Verbesserung einer Fachwerkkonstruktion in mancher Hinsicht führt.The pipe-gusset plate connection presented here according to the patent claims offers a wide range of application and some features that lead to the improvement of a truss construction in some respects.

Die Rohr-Knotenblech-Verbindung ist als ein Handelsprodukt anzusehen und wird in Serie hergestellt. Bei Beachtung bestimmter Herstellungsgrundsätze ist die Anwendung für den Fachmann denkbar einfach. Die Rohr-Knotenblech-Verbindung ist für drei Ausführungsarten bestimmt:

  • - Die feste Rohr-Knotenblech-Verbindung; sie wird in vorgegebene Systemlängen einbezogen (RKVF).
  • - Die längsverschieblich wirkende Rohr-Knotenblech-Verbindung, bei der die Systemlänge nachträglich korrigiert werden kann (±20 mm und mehr). Speziell geeignet für einige Gurtstäbe innerhalb einer Konstruktion, um Überhöhungen zu erzielen, die genau eingestellt werden können (RKVL).
  • - Die drehbare Rohr-Knotenblech-Verbindung als Gegenstück zur längsverschieblich wirkenden Rohr-Knotenblech-Verbindung, aber auch für Zwecke, wo die Knotenbleche nicht in einer Ebene liegen und ein leichtes Anpassen wünschenswert ist (RKVD).
The pipe-gusset plate connection is to be regarded as a commercial product and is manufactured in series. If certain manufacturing principles are observed, the application is extremely simple for the person skilled in the art. The pipe-gusset plate connection is designed for three types:
  • - The fixed pipe-gusset connection; it is included in specified system lengths (RKVF).
  • - The longitudinally displaceable pipe-gusset plate connection, in which the system length can be subsequently corrected (± 20 mm and more). Especially suitable for some belt rods within a construction in order to achieve cantilevers that can be precisely adjusted (RKVL).
  • - The rotatable tube-gusset plate connection as a counterpart to the longitudinally displaceable tube-gusset plate connection, but also for purposes where the gusset plates are not in one plane and easy adjustment is desirable (RKVD).

Alle Rohr-Knotenblech-Verbindungen haben eine optimale Kräfteführung und sind für Momente 2. Ordnung unempfindlich. Durch die sehr kleinen Knotenpunkte werden eindeutige statische Verhältnisse geschaffen.All pipe-gusset plate connections have an optimal force transmission and are insensitive to moments of the second order. The very small nodes create clear static conditions.

Alle Rohr-Knotenblech-Verbindungen nach den Abbildungen 1 bis 3 sind wegen des Doppelkeils an der Keillasche (2) und der entsprechenden Nut in der Keilbacke (3) und (7) schlupffrei und demzufolge einer Paßschrauben- bzw. einer geschweißten Konstruktion gleichzusetzen. Die Sicherung der Keillasche (2) übernimmt eine endseitig aufgeschobene Hülse (4), die durch eine Feder (5) fixiert wird.Because of the double wedge on the wedge plate (2) and the corresponding groove in the wedge jaws (3) and (7), all pipe-gusset plate connections according to Figures 1 to 3 are slip-free and therefore equate to a fitting screw or a welded construction. The wedge flap (2) is secured by a sleeve (4) pushed onto the end, which is fixed by a spring (5).

Alle Rohr-Knotenblech-Verbindungen sind sehr leicht zu montieren, vor allem bewirkt das Einstecksystem eine große Reduktion der Montagezeit (ca. 30-50%) und damit eine Gesamtkostenreduktion.All pipe-gusset plate connections are very easy to assemble. Above all, the plug-in system results in a large reduction in assembly time (approx. 30-50%) and thus a total cost reduction.

Alle Stäbe mit Rohr-Knotenblech-Verbindungen sind auswechselbar bzw. leicht demontierbar.All rods with tube-gusset plate connections are interchangeable or easy to disassemble.

Gegenüber normalen Anschlüssen können die Stäbe mit Rohr-Knotenblech-Verbindungen wegen der verbleibenden sehr kleinen Knotenbleche fast bis zum Anschlußstab herangeführt werden, was zu ästhetisch befriedigenden Lösungen führt.Compared to normal connections, the rods with tube-gusset plate connections can be brought almost up to the connecting rod due to the remaining very small gusset plates, which leads to aesthetically satisfactory solutions.

Für Raumkonstruktionen werden spezielle Knoten, die aus einem Gußteil bestehen, eingesetzt. Sonderknoten mit Anschlüssen für verschiedene Stabdurchmesser werden geschweißt.Special knots consisting of a cast part are used for room constructions. Special knots with connections for different rod diameters are welded.

Vor allem bietet die Rohr-Knotenblech-Verbindung in Abhängigkeit der Materialwahl für die Keilbacken die volle Ausnutzung der Tragkapazität der Hohlprofile.Above all, depending on the choice of material for the wedge jaws, the tube-gusset plate connection offers full utilization of the load capacity of the hollow profiles.

Die Keilbacken (3) und (7) werden in Stahlguß, die Keillaschen (2) ebenfalls in Stahlguß oder gesenkgeschmiedet hergestellt; die Halsringe (6) und (9) sind Drehteile und die Futterscheiben (8) sind Stanzteile.The wedge jaws (3) and (7) are made of cast steel, the wedge plates (2) are also made of cast steel or drop-forged; the neck rings (6) and (9) are turned parts and the chuck discs (8) are stamped parts.

Der Zusammenbau der Rohr-Knotenblech-Verbindung mit dem Hohlprofil (1) in der Werkstatt wird halb- bzw. vollautomatisch vollzogen. Die Herstellung der HV-Schweißnaht zwischen Keilbacke (3) und (7) (Halsring (6) und (9)) und Hohlprofil (1) erfolgt auf einem Rundrohrschweißautomaten, wobei eine Schweißvorrichtung die Lage der Keilbacke (Halsring) justiert und die Stablänge kontrolliert. Somit wird eine Qualitätssicherung mit konstanten Güterresultaten erreicht. Die Schweißung der Keillaschen (2) erfolgt mittels Handschwei- ßung mit Hilfe von entsprechenden Schweißlehren.Assembling the tube gusset plate Connection to the hollow profile (1) in the workshop is carried out semi-automatically or fully automatically. The HV weld seam between the wedge jaw (3) and (7) (neck ring (6) and (9)) and the hollow profile (1) is made on a round tube welding machine, whereby a welding device adjusts the position of the wedge jaw (neck ring) and checks the rod length . This ensures quality assurance with constant product results. The wedge flaps (2) are welded by hand using appropriate welding gauges.

Die Korrosionsschutzbehandlung ist mit allen marktgängigen Verfahren sichergestellt, das heißt, Feuerverzinken, Pulversinterung, Tauchen etc. Beim Feuerverzinken erhalten die festen Rohr-Knotenblech-Verbindungen, Abb. 1, zusätzlich Entlüftungs-, Zinkeinlauf- und Zinkablauflöcher. Bei der längsverschieblich wirkenden Rohr-Knotenblech-Verbindung, Abb. 2, und drehbaren Rohr-Knotenblech-Verbindung, Abb. 3, wird die Keilbacke (3) und (7) anschließend eingesetzt. Bei der drehbaren Rohr-Knotenblech-Verbindung, Abb. 3, wird die Mutter (10), in der eine Spannhülse (11) einbringbar ist, mittels Dorn bei der Feuerverzinkung gehalten.The anti-corrosion treatment is ensured with all standard methods, that is, hot-dip galvanizing, powder sintering, dipping etc. When hot-dip galvanizing, the fixed pipe-gusset plate connections, Fig. 1, are additionally provided with ventilation, zinc inlet and zinc drain holes. The wedge jaws (3) and (7) are then used for the longitudinally displaceable pipe-gusset plate connection, Fig. 2, and the rotatable pipe-gusset plate connection, Fig. 3. In the rotatable tube-gusset plate connection, Fig. 3, the nut (10), in which a clamping sleeve (11) can be inserted, is held by means of a mandrel during hot-dip galvanizing.

Die Anwendungsmöglichkeiten sind durch den Einsatz von Hohlprofilen gegeben, wie zum Beispiel Fachwerkkonstruktion und Raumstrukturen allerArt.The application possibilities are given by the use of hollow profiles, such as truss construction and room structures of all kinds.
