Description
Für Stahlbetonbauten, z. B. Autobahnbrücken, werden Schalgerüste benötigt, die bisher im allgemeinen aus Holz bestanden. Neuerdings sollen dafür auch geschweißte Fachwerkträger aus Rohren verwendet werden. Um nun nicht für verschiedene Spannweiten jeweils verschieden lange Binder herstellen oder vorrätig haben zu müssen, wird erfindungsgemäß vorgeschlagen, den Fachwerkträgei aus mehreren voneinander trennbaren, in sich geschlossenen Binderteilen zusammenzusetzen, die an den Trennstellen mit leicht lösbaren Verbindungsmitteln, z. B. Flanschverbindungen, versehen sind und daß Mittelteile verschiedener Länge zur Erzielung verschiedener Spannweiten austauschbar mit den Endteilen verbunden sind.For reinforced concrete structures, e.g. B. motorway bridges, formwork scaffolding is required, which previously generally consisted of wood. Recently, welded ones are also supposed to be used for this Lattice girders made of tubes are used. To now not for different spans to have to produce or have in stock binders of different lengths in each case proposed according to the invention, the framework contributions from several separable, assemble self-contained binder parts, which at the separation points with easily detachable connecting means, e.g. B. flange connections are provided and that middle parts of different lengths to achieve different spans interchangeable are connected to the end parts.
Zweckmäßig wird an die lösbare Knotenpunktverbindung ein senkrechter Zapfen angeschweißt, der zum Anbringen einer Rohrgerüstkupplung an den zusammensetzbaren Binder bestimmt ist.Appropriately, a vertical connection is attached to the detachable junction connection Stud welded on, which is used to attach a pipe frame coupling to the assemblable Binder is intended.
Auf der Zeichnung ist in Abb. i schematisch ein Fachwerksträger gemäß der Erfindung aus den Endteilen i und 2 und den Mittelteilen 3 und 4 dargestellt. In Abb. 2 ist im vergrößerten Maßstab ein lösbarer Knotenpunkt gezeigt, während Abb.3 eineu Längsschnitt durch zwei verbundene Gurtrohre er kennen läßt. Die Gurtrohe 5 und 6 sind mittels Flanschen i und 8 und Schrauben miteinander verbunden. Die Strebenrohre y und io sind neben diesen Flanschen an die Gurtrohre angeschweißt. Ein Zapfen i t dient zum Anbringen einer Gerüstkupplung.In the drawing, a truss is shown schematically in Fig. I of the invention from the end parts i and 2 and the middle parts 3 and 4 shown. In Fig. 2, a detachable node is shown on an enlarged scale, while Fig.3 shows a longitudinal section through two connected belt tubes. The belt tubes 5 and 6 are connected to one another by means of flanges i and 8 and screws. the Strut tubes y and io are welded to the chord tubes next to these flanges. A pin i t is used to attach a scaffold coupling.
Durch Ersatz eines Binderteiles durch einen anderen mit anderer Spannweite oder durch Herauslassen eines Mittelteiles überhaupt lassen sich die Gesamtspannweiten weitgehend verändern.By replacing one part of the truss with another with a different span or by leaving out a middle part at all, the total spans can be determined largely change.
