Abstract
Knotenverstärkung für Gerippestrukturen aus Vierkantrohren, insbesondere für Seitenwände von Omnibussen, wobei die Gerippestrukturen Öffnungen für den Einsatz von Türen und/oder Fenstern aufweisen und an Knotenpunkten (10) von Vierkantrohren (11, 12), besonders an einer Öffnung des Gerippes für eine Tür oder ein Fenster, mindestens eine an den Vierkantrohren (11, 12) angeschweißte Knotenschale (13) vorgesehen ist, dadurch gekennzeichnet, dass die wenigstens eine Knotenschale (13) zwei Schalenteile (15, 15') aufweist, die nur an gegenüberliegenden Seitenwänden der Vierkantrohre (11, 12) derart befestigt sind, dass die Schalenteile (15, 15') jeweils auf einer Seite ausschließlich an den angrenzenden in einer Ebene liegenden Seitenwänden zweier Vierkantrohre (11, 12) außerhalb der Kantenbereiche der Vierkantrohre (11, 12) angeschweißt sind.Node reinforcement for skeleton structures square tubes, in particular for sidewalls of buses, the Rib structures openings for use of doors and / or windows and at junctions (10) of square tubes (11, 12), especially at an opening of the skeleton for a door or a window, at least one of the square tubes (11, 12) welded Node shell (13) is provided, characterized in that the at least one node shell (13) has two shell parts (15, 15 '), the only on opposite sidewalls the square tubes (11, 12) are fastened such that the shell parts (15, 15 ') each on one side exclusively to the adjacent in a plane lying side walls two square tubes (11, 12) outside the edge regions the square tubes (11, 12) are welded.
Description
Die Erfindung betrifft eine Knotenverstärkung für Gerippestrukturen nach dem Oberbegriff des Anspruches 1.The The invention relates to a node reinforcement for skeletal structures according to the Preamble of claim 1.
Aus
der deutschen Patentschrift
Aber genau diese Art der Verschweißung, auch schon Verschweißungen bei denen die Schweißnaht an Kanten von Vierkantrohren ausläuft, sind bei den Belastungen aus den auftretenden Biegemomenten kritisch.But just this kind of welding, too already welds where the weld at the edges of square tubes leaking, are at the loads from the occurring bending moments critical.
Es sind deshalb alle Schweißungen oder Schweißnahtenden an den Kanten von Vierkantrohren im Hinblick auf die Betriebsfestigkeit besonders kritisch.It are therefore all welds or weld ends at the edges of square tubes in terms of durability especially critical.
Aus
diesem Gesichtpunkt ist auch der Gegenstand der
Dabei werden auch Kanten miteinander verschweißt. Die Schweißverbindungen bieten zwar gute Eckversteifungen und sind für unsere und ähnliche Straßenverhältnisse gut geeignet, bei schlechten Straßenverhältnissen können jedoch Schwächen im Gerippe sichtbar werden.there Even edges are welded together. The welded joints Although offer good corner stiffeners and are for ours and similar road conditions well suited, in bad road conditions, however, weaknesses in the skeleton become visible.
In
der
Aufgabe der Erfindung ist es, Knotenpunkte von Gerippen so zu verstärken, daß sie bei geringem Materialaufwand hohen Belastungen standhalten.task The invention is to reinforce nodes of skeletons so that they at withstand low loads and high loads.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The The object is achieved by the Characteristics of claim 1 solved.
Dadurch, daß eine Knotenschale gebildet ist, die nur mit den Seitenwänden der zu verbindenden Vierkantrohre verschweißt ist, treten an den Kanten der Vierkantrohre keine weiteren Spannungsspitzen durch die Schweißnaht auf.Thereby, that one Node shell is formed only with the side walls of the welded to connecting square tubes, occur at the edges of the Square tubes no further stress peaks through the weld.
An den Kanten von Vierkantrohren sind in der Nähe von Knoten aus den Belastungen aus Biegemomenten oft hohe Spannungen. Dies gilt besonders für Tür- und Fensterpfostenanschlüsse bei Seitenwänden von Omnibussen. Deshalb ist es zu vermeiden, daß Schweißnähte direkt an einer Kante eines Vierkantrohres in der Nähe von Knotenpunkten des Gerippes angebracht werden. Selbst eine Schweißnaht, die in der Nähe der Kante ausläuft, kann Festigkeitsprobleme mit sich bringen.At The edges of square tubes are near knots from the strains bending moments often cause high tensions. This is especially true for door and window post connections sidewalls of buses. Therefore it is necessary to avoid that welds directly at an edge of a Square tube nearby be attached by nodes of the skeleton. Even a weld that near the edge runs out, can Strength problems.
Die erfindungsgemäße Knotenschale wird deshalb nur an den Seitenwänden von Vierkantrohren angeschweißt.The Node shell according to the invention is therefore only on the side walls welded by square tubes.
Damit ein möglichst kerbwirkungsfreier Übergang in den Gurt der Knotenschale erfolgt, ist die knotenabgewandte Seite entsprechend geformt.In order to one possible non-impact transition takes place in the belt of the node shell, is the knot-facing side shaped accordingly.
Damit ein Schweißer nicht erst in Versuchung kommt, den Gurt der Knotenschale mit der dritten Wand des Vierkantrohres zu verschweißen, sind die stirnseitigen Enden des Gurtes bogenförmig konkav ausgestaltet. Durch diese Ausgestaltung kann sich auch kein Kondensat im Knotenbereich ansammeln.In order to a welder not tempted, the girdle of the nodal shell with the third Weld the wall of the square tube are the frontal Ends of the belt arcuate concave designed. By this configuration, no condensate can accumulate in the node area.
Die Schweißung des Knotens zwischen Pfosten und Gurt wird vor dem Anschweißen der Knotenschale durchgeführt. Damit nun die Schweißnaht nicht geschwächt wird, ist es gut, wenn sie nicht verputzt werden muß. Das Verputzen kostet auch Geld. Deshalb sind die Ecken der Deckbleche der Knotenschale rechtwinklig ausgenommen, damit bei unverputzter Schweißnaht Knotenschale und Schweißnaht nicht miteinander kollidieren.The welding of the node between the post and the strap is before welding the node shell carried out. So now the weld not weakened it is good if it does not have to be plastered. The plastering also costs money. Therefore, the corners of the cover plates of the node shell except at right angles, so that in the case of bare welds node shell and weld do not collide with each other.
Durch die flächenförmige Anlage der Knotenschale an den Seitenwänden der Vierkantrohre eignet sich die Knotenschale auch gut zur Klebung.Due to the planar arrangement of the nodal shell on the side walls of the square tubes the nodal shell is also good for gluing.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.In the drawing is an embodiment of Invention shown schematically.
