Description

Knotenpunktausbildung für geschweißte Tragwerke Gegenstand des Hauptpatents ist die besiondere Ausbildumg genes Knotenpunktes für geschweißte Tragwerke, bei dem die Tragwerkstahenden an einem -hohlen Knotenstück i stumpf angeschweißt sind.The subject of the main patent is the formation of junctions for welded structures is the special training course for welded structures at to which the structural steel ends are butt-welded to a hollow junction piece i.

Nach dem Hauptpatent . sind bei einer derartigen n Knotenpunktausbildung die Scbweißnahtverbindung@en des Knotenstückes mit den Tragwerkstabenden durch je ein Stahlstabbündel verstärkt, das sich vom Innern des Knotenstückes aus über die Stumpfschweißnaht hinweg bis in das hohle Ende des Tragwerkstabss @erstneckt und 'das auf seiner ganzen Länge in eine das Stahlstabbündel mit i dem Kniotenstück und dem Stabende verbindende, erhärtete Masse eingebettet ist, die in dien vom hohlen Knotenstück und den hohlen Tragwerkstabenden gebildeten Hohlraum eingepreßt ist.According to the main patent. are in such an n node formation the welded seam connection @ en of the junction piece with the structural bar ends through each reinforced a steel rod bundle that extends from the inside of the knot over the Butt weld away into the hollow end of the structural bar and 'that along its entire length into a bundle of steel bars with the knee piece and the rod end connecting, hardened mass is embedded, which is in the hollow Node and the hollow structural rod ends cavity formed is pressed.

Zweck der vorliegenden Erfindung ist eine Verbesserung derKnotenpunktausbildung nach dem Hauptpatent hinsichtlich der Entlastung der Schweißnaht und damit hinsichtlich der Sicherheit und Festigkeit der Schweißnahtverbinden gen.The purpose of the present invention is to improve node formation according to the main patent with regard to the relief of the weld seam and thus with regard to the safety and strength of the weld seams.

Die Erfindung besteht darin, d,aß jeder Stab des Stahlstabbündels aus einem um seine Län.gsachs@e verwundenen Mehrkantst,ab oder aus zwei oder mehr miteinander verdrillten normalen Rundstäben besteht. Durch die-Verwendung der verwundenen Mehrkantstäbe bzw. der aus miteinander verdrillten normalen Rundstäben bestehenden Stäbe soll insbesondere der Reibungswiderstand an den inneren Flächen der hohlen Tragwerkstabenden und des hohlen Knotenstückes wesentlich erhöht werden, lohne daß dabei die Haftfläche der Füllnasse an den Innenwandungen der Tragwerkstabenden und des hohlen Knotenstückes vergrößert werden müßte. Abgesehen davon bedingt die Verwendung der verwundenen bzw. verdrillten Bewehrungsstäbe schon im Hinblicl auf die :erhöhte Streckgrenze und Bruchfestigkeit solcher Stäbe einen wesentlichen Fortschritt hinsichtlich der Entlastung der Schweißverbin.dungsnähte.The invention consists in d, ate each rod of the steel rod bundle from a polygon twisted around its length, from or from two or more normal round rods twisted together. By using the twisted Polygonal bars or those consisting of normal round bars twisted together Specifically, the rods are designed to provide frictional resistance on the inner surfaces of the hollow Structural bar ends and the hollow node piece are significantly increased, it is worthwhile while the adhesive surface of the filling liquid on the inner walls of the structural rod ends and of the hollow knot would have to be enlarged. Apart from that, the usage is conditional of the twisted or twisted reinforcement bars with regard to the: increased Yield strength and breaking strength of such rods represent a significant advance in terms of the relief of the welded connection seams.

Nach der Erfindung werden als Bewehrungsstäbe Stäbe von erhöhter Streckgrenze und Bruchfestigkeit, und zwar um ihre Längsachse verwundene einzelne Mebrkantstäbe oder aus zwei oder mehr miteinander verdrillten normalen Rundeisen gebildete Stäbe benutzt, wie sie im Eis:enbet@onbau an sich bekannt sind. Infolge der Verwindung ist nicht nur die Streckgrenze der Stäbe und deren Bruchfestigkeit erhöht, sondern die Drallzüge der Stäbe wandeln auch in der Stabachse wirkende Zug-oder Druckkräfte zum Teil in radial gerichtete Druckkräfte um. Hierdurch wird die Haftung zwischen den Bewehrungsstäben und der Füllmasse sowie zwischen dieser und den Innenwandflächen des hohlen Tragwerkstabes und des hohlen Knotenstückes erhöht und die Schweißnaht wesentlich entlastet.According to the invention, bars of increased yield strength are used as reinforcing bars and breaking strength, namely individual Mebrkant rods twisted around their longitudinal axis or rods formed from two or more normal round bars twisted together used as they are known in the ice: enbet @ onbau. As a result of the twist is not only increased the yield strength of the rods and their breaking strength, but the twisting forces of the rods also convert tensile or compressive forces acting in the rod axis partly in radially directed pressure forces. This will reduce the liability between the reinforcing bars and the filling compound and between this and the inner wall surfaces of the hollow structural member and of the hollow knot piece increased and the weld seam is significantly relieved.
