Abstract
Description
Die Erfindung betrifft ein Gerüstrohr mit einem Rohr und mindestens einem Anschlußkopf, der Außenbegrenzungsflächen aufweist, die keilartig auf ein Zentrum zusammenlaufend gestaltet sind, der eine Keilöffnung aufweist, der aus Stahlguß, Temperguß oder geschmiedetem Stahl besteht und der am Rohr zentriert angeschweißt ist, wobei das rohrseitige Ende des Anschlußkopfes eine für das Verschweißen geeignete Ausbildung seines Verbindungsbereiches aufweist und dafür in das Rohr ragende, passende Zentrierhilfsteile hat und am Anschlußkopf (25) eine Anstoßringfläche (51) für das Rohr (21) gebildet ist.The invention relates to a scaffold tube with a tube and at least one connection head, the outer boundary surfaces which is wedge-like on a center are designed to converge, the one wedge opening has that of cast steel, malleable cast iron or forged Steel exists and is welded to the center of the pipe is, the pipe end of the Connection head one suitable for welding Has formation of its connection area and suitable centering auxiliary parts protruding into the pipe has and an abutment ring surface (51) for the tube (21) is formed on the connection head (25).
Gerüstrohre mit den vorstehend abgedruckten Merkmalen sind aus EP-A-0 276 487 A2 bekannt. Dabei sind an den Enden von Gerüstrohren aus Leichtmetall-Strang-Preßprofil Anschlußköpfe aus Stahlguß, Temperguß oder geschmiedetem Stahl vorgesehen, die mittels geeigneter Fortsätze in die Gerüstrohre eingesteckt und dort befestigt sind. Quer durch die Fortsätze erstrecken sich Befestigungsdurchbrechungen. In diese werden bei der Fertigung kalottenartige Verformungsbereiche des aufgesteckten und aufgepreßten Gerüstrohres zur Sicherung gegen Verdrehen und Abziehen hineingedrückt. Zusätzlich oder alternativ hierzu kann der jeweilige Anschlußkopf an dem Gerüstrohr mittels Schweißen befestigt sein. Hierzu weist der Anschlußkopf eine hintere Anlagestirnfläche auf, die nach außen hin durch eine senkrecht zu dieser und fluchtend zur äußeren Oberfläche des Gerüstrohres verlaufenden zylindrischen Fläche begrenzt wird, so daß sich eine Stoß-Naht ergibt. Dadurch bedingt und wegen der relativ langen, dickwandigen Gestaltung der Fortsätze ergeben sich ungünstige Wärmeleitverhältnisse und deshalb ungünstige Automatenschweißverhältnisse.Scaffolding tubes with the ones printed above Features are known from EP-A-0 276 487 A2. there are at the ends of scaffold tubes made of extruded light metal Connection heads made of cast steel, malleable cast iron or forged steel provided by means of suitable extensions inserted into the scaffold tubes and are attached there. Extend across the extensions fixing holes. In these become dome-like deformation areas during production of the attached and pressed on scaffold tube to prevent twisting and pulling pushed in. Additionally or alternatively, this can the respective connection head on the scaffold tube by means of Welding. The Connection head on a rear face, the outwards through a perpendicular to this and aligned with the outer surface of the scaffold tube extending cylindrical surface is limited, so that there is a butt seam. Because of this and because of the relatively long, thick-walled design of the Extensions result in unfavorable thermal conduction and therefore unfavorable automatic welding conditions.
Aus DE-PS 24 49 124 sind seit langem verwendete Gerüstrohre mit Anschlußköpfen bekannt. Die Anschlußköpfe werden in der Regel aus Temperguß gefertigt und haben für die Zentrierung im anzuschweißenden Rohr wenigstens drei Zapfen oder Zentrierlappen, die auf den Innendurchmesser des Gerüstrohres abgestimmt sind. Eine geringfügig über den Innendurchmesser überstehende stirnseitige Positionierungsfläche, die normal auf der Rohrachse steht, ist nur im Bereich des Innendurchmessers des Rohres durchlaufend ausgeführt. Die Außenteile der Positionierungsfläche sind in den Bereichen von seitlichen, vertikal verlaufenden, nach hinten in Richtung auf das Gerüstrohr leicht geneigten Flächen unterbrochen. So kommt für die Befestigung nicht ringsum ein gleichmäßig durchlaufender Nahtgrund zustande. Vielmehr wird teilweise ein L-Nahtgrund angeboten und in den Seitenbereichen muß eine 1-Naht gelegt werden. Dadurch und durch die Materialgegebenheiten ergeben sich beim Ringsum-Schweißen mit Schweißautomaten Ungleichmäßigkeiten mit ihren Folgen.From DE-PS 24 49 124 have long been used Scaffold tubes with connection heads known. The connection heads are usually made from malleable cast iron and have to be welded for centering Tube at least three pins or centering tabs, which are matched to the inside diameter of the scaffold tube are. A little over the inside diameter protruding face positioning surface, the is normal on the pipe axis, is only in the area of The inside diameter of the pipe is continuous. The outer parts of the positioning surface are in the areas of lateral, vertical, slightly inclined towards the back of the scaffold tube Interrupted areas. So comes for attachment not an evenly continuous all around Seam bottom. Rather, it sometimes becomes an L-seam base offered and must in the side areas a 1-seam can be made. Because of this and through the material conditions result from all-round welding with welding machines irregularities with its consequences.
Die Erfindung ist nicht nur für die konkret bekannte Gestaltung geeignet, sondern auch für andere, ähnliche Anschlußköpfe mit zugehörigen Elementen, bei denen sich ähnliche Probleme ergeben.The invention is not only for the specifically known Design suitable, but also for others, similar Terminal heads with associated elements where similar problems arise.
Aus DE 32 36 648 A1 ist ein Gerüst, insbesondere Baugerüst, mit tassenartigen Verbindungselementen auf den Stielen und in diese eingehängten Hakenanschlußköpfen bekannt. Solche Anschlußköpfe werden an den langgestreckten Gerüstelementen durch Schweißen befestigt. Dafür ist gemäß der zeichnerischen Darstellung ein Ansatz vorgesehen, der an das freie Ende des Horizontalriegels angepaßt und zweckmäßigerweise mittels einer Schweißnaht befestigt ist. Für das Einstecken, Zentrieren und Befestigen ist eine durchlaufende Konusfläche ohne besondere Ausricht-Hilfsmittel vorgesehen, die zu einer Verschweißung mit V-Naht oder L-Naht führt. Die genaue Ausrichtung zum Rohr bei der Verschweißung erfordert entsprechend ausrichtende Hilfsmittel, da eine Anstoßfläche bzw. Anstoßringfläche fehlt.DE 32 36 648 A1 describes a scaffold, in particular Scaffolding, with cup-like connecting elements on the stems and in these hooked connection heads known. Such connection heads will on the elongated scaffolding elements Welding attached. For this is according to the graphic Representation provided an approach to the Free end of the horizontal bar adjusted and expedient is attached by means of a weld seam. For insertion, centering and fastening is one continuous conical surface without special alignment aids provided for a weld with V-seam or L-seam leads. The exact alignment to Pipe when welding requires accordingly aligning aids, as a bump surface or bump ring surface is missing.
Aus DE 31 21 141 A1 - Fig. 7 - ist ein Anschlußkopf für eine tassenartige Verbindung bekannt, der für den Eingriff in das Ende des langgestreckten Gerüstelements einen Zentriereinsatz mit gerundeter Endausbildung aufweist, der in das Rohrende gesteckt wird. Dabei setzt der innere Rand des Rohrendes auf dem gerundeten Übergang zwischen Anschlußkopf und Zapfen in wenig genau definierter Form auf. Eine Fase am Rohr gestattet die Anbringung einer V-Naht.From DE 31 21 141 A1 - Fig. 7 - is a connection head known for a cup-like connection, which for the Engagement in the end of the elongated scaffolding element a centering insert with rounded end formation has, which is inserted into the pipe end. there puts the inner edge of the pipe end on the rounded Transition between connection head and spigot in a little precisely defined form. A chamfer on the pipe allows the application of a V-seam.
Bei der Verbindung eines schlüssellochartigen
Steckelementes mit einem Gerüstrohr nach DE 27 04
398 A1 ist diese derart ausgeführt, daß ein Keilformteil
mit einer geraden Fläche vor die gerade Abschnittfläche
des Rohres gelegt und in Teilbereichen mit V-Nähten
angeschweißt ist. Eine integrierte Ausrichthilfe am Keilformteil
fehlt. Aus DE 30 05 128 A1 ist ein Anschlußkopf
mit den vorn genannten Merkmalen zu entnehmen, der
einen üblichen Ansatz für das Befestigen an einem Rohr
enthält. Nähere Einzelheiten über die Verbindung sind
der Schrift nicht zu entnehmen.When connecting a keyhole-like
Plug-in element with a scaffold tube according to DE 27 04
398 A1 this is designed such that a wedge shaped part
with a straight surface in front of the straight section surface
of the pipe and in some areas with V-seams
is welded on. An integrated alignment aid on the wedge molding
is missing.
Der Erfindung liegt die Aufgabe zugrunde, die Gestaltung der Verbindung des Anschlußkopfes mit dem Gerüstrohr so zu verbessern, daß sich unter Einhaltung der durch das Baukastensystem vorgegebenen Abmessungen solcher Anschlußköpfe, bei guten Zentrier- und Ausrichtbedingungen günstigere Automatenschweißbedingungen ergeben.The invention has for its object the design the connection of the connection head with the scaffold tube to improve so that in compliance with the the modular system given dimensions of such Connection heads, with good centering and alignment conditions more favorable automatic welding conditions surrender.
Erfindungsgemäß sind in der in den Ansprüchen 1 bis 4 beschriebenen Ausführungsform der Erfindung wenigstens die nachfolgend abgedruckten Merkmale vorgesehen:
- daß die Anstoßringfläche (51) einen Außendurchmesser (54) aufweist, der kleiner als der Außendurchmesser (41) des Gerüstrohres (21) ist,
- daß sich daran nach außen eine sich nach vom erweiternde Konusfläche anschließt,
- daß sich an die Konusfläche eine Zylinderfläche anschließt, deren Durchmesser dem Außendurchmesser des Gerüstrohres gleich ist oder geringfügig größer als dieser ist, und
- daß die obere Zylinderteilfläche im oberen Bereich der Mitte von dem hinteren Schwenkbereich der Keilöffnung ganz etwas angeschnitten ist.
- that the abutment ring surface (51) has an outer diameter (54) which is smaller than the outer diameter (41) of the scaffold tube (21),
- that this is followed by an outwardly extending conical surface,
- that a conical surface adjoins the conical surface, the diameter of which is equal to or slightly larger than the outer diameter of the scaffold tube, and
- that the upper cylinder partial surface in the upper area of the middle is slightly cut from the rear pivoting area of the wedge opening.
Dadurch, daß eine ringsum stetig durchlaufende,
sich vom Innenrand nach außen mit gleicher Ringbreite
erstreckende Anstoßringfläche ausgebildet ist, die auf
ihrem Außendurchmesser in eine nach vorn sich erweiternde
als Konusfläche bezeichnete Teilkegelfläche
übergeht, ergibt sich ein durchlaufender Nutgrund, der
die Form einer halben V-Naht hat, wobei die Rohrkante
infolge des Schmelzvorganges gleichmäßig abgeschmolzen
werden kann, während die angrenzende
Tempergußwand überall nahezu gleichmäßige Bedingungen
des Grundes bietet, die somit zu einem gleichmäßigen
Abbrand, einem gleichmäßigen Nahtbild und
damit zu einer ringsum gleichmäßigen, hochfesten Verschweißung
gemäß den gewählten Materialbedingungen
führt.
Dadurch, daß sich an die Konusfläche eine Zylinderfläche
anschließt, deren Durchmesser dem Außendurchmesser
des Gerüstrohres gleich ist oder geringfügig
größer als dieser ist und dadurch, daß die obere Zylinderteilfläche
im oberen Bereich der Mitte von dem hinteren
Schwenkbereich der Keilöffnung angeschnitten
ist, werden bei dem konstuktiv durch das Baukastensystem
vorgegebenen Rahmen die Schweißbedingungen
verbessert.Due to the fact that an abutment ring surface which is continuous all the way around and extends from the inner edge to the outside with the same ring width and whose outer diameter merges into a part-conical surface which widens towards the front and is called a cone surface, this results in a continuous groove base which has the shape of a half V Seam has, whereby the pipe edge can be melted evenly as a result of the melting process, while the adjacent malleable cast iron wall offers almost uniform conditions of the bottom everywhere, which therefore leads to a uniform burn-off, a uniform seam pattern and thus to an evenly uniform, high-strength welding in accordance with the selected material conditions .
The fact that a conical surface adjoins the conical surface, the diameter of which is equal to or slightly larger than the outer diameter of the scaffold tube, and that the upper partial cylinder surface is cut in the upper region of the middle by the rear pivoting region of the wedge opening, are constructive in the latter the welding conditions are improved by the framework specified by the modular system.
Dazu trägt weiter bei, daß die Konusfläche und die Zylinderfläche in den im wesentlichen vertikalen seitlichen Randbereichen mit nahezu kontinuierlichem Übergang in die auf gleichem Außenradius und mit annähernd gleicher Neigung verlaufende Keilflächenteile übergeht.This also contributes to the fact that the conical surface and the Cylinder surface in the essentially vertical lateral Border areas with an almost continuous transition in the same outer radius and with approximately Wedge surface parts running at the same inclination transforms.
In weiterer sinnvoller Ausgestaltung kann der Anschlußkopf gemäß Anspruch 4 in seinen über den Durchmesser des Gerüstrohres hinausragenden Teilen rückseitig von einer sich an den zylindrischen Teil im Verbindungsbereich anschließenden Kugelteilfläche begrenzt sein. So ist die für den aus der Belastung resultierenden Kraftfluß erforderliche Materialmenge an günstigen Stellen angeordnet und es sind hinreichend Freiräume für das Ringsum-Verschweißen ohne Beeinträchtigung der Stabilität des Anschlußkopfes bei geringerem Materialaufwand und günstigen Platzbedingungen für die Schweißgeräteteile erzielt.In a further useful embodiment, the connection head according to claim 4 in its about Parts of the scaffold tube protruding on the back of one on the cylindrical part in Connection area adjoining spherical surface be limited. So is that for the one resulting from the stress Force flow required amount of material arranged favorable places and there are sufficient Free space for all-round welding without interference the stability of the connection head with less Material expenditure and favorable space conditions achieved for the welding machine parts.

Jeder Anschlußkopf 25 hat einen Verbindungsbereich
30, einen Lochscheiben-Schlitz 31 sowie Anlageflächen
32, mittels deren er sich an dem Stiel 11 abstützt,
wenn er mit dem Lochscheiben-Schlitz 31 über
eine Lochscheibe 17 in bekannter Weise gesteckt ist.
Er hat vertikal übereinander liegende Keilöffnungen
33.1 und 33.2, durch die der Keil 26 geführt ist. Die obere
Keilöffnung 33.1 ist im Randbereich mit einem nach
innen ragenden Anschlagwulst 34 für die Anlage des
der Verliersicherung dienenden Nietes 27 gestaltet. Sie
ist im hinteren Schwenkbereich 33.3 in bekannter Weise
offen, so daß man den Keil 26 nach hinten schwenken
kann, wenn sich die Köpfe des Niet 27 an den gegenüberliegenden
Anschlagwülsten 34 abstützen.Each
Im übrigen sind die Keilöffnungen 33.1 und 33.2 so
breit, daß die Köpfe des Niet 27 bequem durchgeführt
werden können. Zur Verbesserung des Aufsteckens
des Anschlußkopfes 25 auf die Lochscheibe 17 hat der
Lochscheiben-Schlitz 31 ausgerundete Einführecken
36, die ebenfalls in bekannter Weise gestaltet sind.Otherwise, the wedge openings 33.1 and 33.2 are like this
wide that the heads of the rivet 27 carried comfortably
can be. To improve the attachment
of the
Der ganze Anschlußkopf 25 ist - in der Draufsicht
(Fig. 4) gesehen - keilartig nach innen auf das Stiel- und
Scheibenzentrum 37 zulaufend gestaltet, wobei die Außenbegrenzungsflächen
38.1 und 38.2 in den Randkonturen
ihrer nach außen ragenden Wülste eben gestaltet
sind, wie es auch bei bisherigen Anschlußköpfen üblich
war Das ist so gemacht, damit man auch diagonal verlaufende
Stäbe anschließen und deren Anschlußköpfe
möglichst eng an die Außenbegrenzungsflächen der
Anschlußköpfe rechtwinklig zueinander stehender Stäbe
anlegen kann. Die Außenbegrenzungsflächen 38.1
und 38.2 haben zur Gewichtseinsparung zwischen ihren
Wülsten Vertiefungen 39.1 und 39.2, die ebenfalls
im wesentlichen in bekannter Weise gestaltet sind.The
Die rückseitige Abschlußfläche 40 der massiven
Materialbereiche des vorderen Anschluß-Kopfteiles ist
in Abweichung von der bisherigen Art nicht als Ebene,
sondern als nach außen geneigte Fläche gestaltet, wie
es die Fig. 2 und 5 zeigen. Dabei wählt man zweckmäßig
die Form einer Teilkugel. Dadurch erreicht man, daß
bei unveränderter Stabilität des ganzen Anschlußkopfes
25 die für die Befestigung um den Verbindungsbereich
herumzuführenden Schweißeinrichtungen freier
geführt und geeigneter gestaltet werden können, um eine
verbesserte Verschweißung im Verbindungsbereich
30 zu erzielen. Diese als Teilkugelflächen ausgebildeten
Abschlußflächenteile der Abschlußfläche 40 erheben
sich aus Zylinderteilflächen 45, die etwa den Außendurchmesser
41 des Rohres 21 haben. Die obere Zylinderteilfläche
45 ist nur im oberen Bereich in der Mitte
ganz etwas von dem hinteren Schwenkbereich 33.3 der
oberen Keilöffnung 33.1 angeschnitten. Die obere und
die untere Zylinderteilfläche gehen in den vertikalen
Randbereichen, die unmittelbar an die Außenbegrenzungsflächen
38.1 und 38.2 anschließen, in Schrägflächen
47.1 und 47.2 über - wie es inbesondere Fig. 5 -
deutlich zeigt. Diese Schrägflächen 47.1 und 47.2 reichen
in etwa bis zum Nutgrund 49 der Schweißnaht 50.The
Der Nutgrund 49 wird von einer über den ganzen
Schweißbereich durchlaufenden Anstoß-Ringfläche 51
begrenzt. Die Anstoß-Ringfläche 51 hat als innere Begrenzung
einen Kreis, der etwa so groß ist wie der Innendurchmesser
53 des Gerüstrohres 21. Ihr Außendurchmesser
54 ist so gewählt, daß sich eine günstige
V-Naht-Verschweißung ergibt. Es schließt sich an die
Anstoß-Ringfläche 51 eine sich nach vorn erweiternde
Konusfläche 55 an, die zusammen mit der gerade abgeschnittenen
Endfläche 56 des Gerüstrohres 21 die
halbe V-Naht zum Verschweißen begrenzt, wobei diese
Konusfläche 55 nur mit ganz geringer Abknickung in die
seitlichen Schrägflächen 47.1 und 47.2 praktisch kontinuierlich
übergeht, so daß sich keine Unterbrechungen
des Materialflusses beim durchlaufenden Einbringen
der Schweißnaht ergeben. Durch die Vereinigung dieser
Gestaltungsmerkmale ist gewährleistet, daß man einerseits
zur Austauschbarkeit im Baukastensystem die
bisher üblichen Abmessungen solcher Anschlußköpfe
einhalten und andererseits trotzdem bessere Verschweißung
erzielen kann.The
Zur Zentrierung beim Aufsetzen des Anschlußkopfes
25 auf das Gerüstrohr 21 sind nach innen ragende,
in das Gerüstrohr 21 passende Zentrierlappen 60 vorgesehen,
deren äußere Begrenzung dem Innendurchmesser
53 des Gerüstrohres 21 entspricht und die im
übrigen abgeschrägt in die Innenöffnung 61 übergehen.
Sie haben eine Breite, die etwas weniger als 1/8 des
Umfanges betragen kann. Ihre Größe richtet sich nach
den Gestaltungsmöglichkeiten und dem vertretbaren
Gewicht unter Berücksichtigung dessen, daß sie beim
Montieren und Verschweißen hinreichend stabil sind
und nicht behindern. Sie sind in ähnlicher Weise schon
bisher gestaltet worden.For centering when attaching the
Durch die vorteilhafte, neue Gestaltung des Verbindungsbereiches
30 mit der Anstoß-Ringfläche 51 und
mit der angrenzenden Konusfläche 55 und Einbeziehung
der übrigen sinnvollen Flächengestaltungen ergeben
sich wesentlich verbesserte Schweißbedingungen,
die die Sicherheit der Verbindung für die Bauteile wesentlich
fördern und somit zur Gesamtsicherheit der Gerüste
wesentlich beitragen. Gleiche Anschlußköpfe können
mit den entsprechenden Einrichtungen an einem
kurzen Gerüstrohrstück auch zum Anschluß von Diagonal
stäben verwendet werden und auch für sonstige Hilfseinrichtungen
benutzt werden, indem das Gerüstrohrstück
entsprechend gestaltet wird.Due to the advantageous, new design of the
Zusammengefaßt kann die Erfindung auch wie folgt
beschrieben werden:
Der Anschlußkopf (25) für Gerüste mit Verbindungsvorrichtungen
hat einen Verbindungsbereich (30), der Zentrierlappen
(60) aufweist und eine Anstoß-Ringfläche
(51) sowie eine Konusfläche (55) zur Schaffung günstiger
Schweißbedingungen besitzt. In summary, the invention can also be described as follows:
The connection head (25) for scaffolding with connecting devices has a connecting area (30) which has centering tabs (60) and has an abutting ring surface (51) and a conical surface (55) to create favorable welding conditions.
