Die Gasversorgung von insbesondere Haushalten erfolgt über im Erdreich verlegte Hauptverteilerrohre. Ist ein Hausanschluß herzustellen, wird im Erdreich eine vom Haus an das Hauptver teilerrohr heranlaufende Hausanschluß-Leitung verlegt. Diese heranlaufende Leitung muß dann über einen herzustellenden Ab zweiganschluß an das Hauptverteilerrohr angeschlossen werden. Sind die Leitungen bereits im Erdreich verlegt, wird der Erdbo den im Abzweigbereich aufgegraben, so daß der Abzweiganschluß hergestellt werden kann. Dazu wird ein Verbindungsformstück be nutzt, das als auf das Hauptverteilerrohr an geeigneter Stelle aufsetzbarer Anbohrsattel ausgebildet ist. Der Anbohrsattel wird so auf das Hauptverteilerrohr gesetzt, daß sein Abzweig rohrstück mit der heranlaufenden Hausanschluß-Leitung verbun den werden kann. Sodann wird der Anbohrsattel mit dem Hauptver teilerrohr durch Schmelzschweißen verbunden und der Anschluß des Abzweigrohrstückes an die heranlaufende Hausanschluß-Lei tung vorgenommen. Mit einem geeigneten Werkzeug kann durch ei nen verschließbaren Stutzen hindurch, welcher mit dem Anbohr loch im Anbohrsattel fluchtet, die Wandung des Hauptverteiler rohres durchbohrt werden, so daß nunmehr aus dem Hauptvertei lerrohr Gas in die abzweigende Hausanschluß-Leitung strömen kann.The gas supply of households in particular takes place via Main distribution pipes laid in the ground. Is a house connection to manufacture, is in the ground one from the house to the main ver divider pipe approaching house connection line laid. These approaching line then has to be manufactured from branch connection can be connected to the main distribution pipe. If the lines are already laid in the ground, the Erdbo dug up in the branch area so that the branch connection can be manufactured. For this, a connection fitting is uses that as a suitable place on the main manifold attachable tapping saddle is formed. The tapping saddle is placed on the main manifold so that its branch Pipe section connected to the incoming house connection pipe that can be. Then the tapping saddle with the main ver manifold connected by fusion welding and the connection of the branch pipe piece to the approaching house connection line tion made. With a suitable tool, ei NEN lockable nozzle, which with the tapping hole in the tapping saddle is aligned, the wall of the main distributor pipes are pierced, so that now from the main distribution Flow the gas pipe into the branching house connection pipe can.
Bei der Verbindung des Abzweigrohrstückes mit der heran laufenden Hausanschluß-Leitung treten häufig montagetechnische Schwierigkeiten auf, insbesondere dann, wenn die Hausan schluß-Leitungen unter verschiedenen Winkeln an das Haupt verteilerrohr heranlaufen. Zur Ausrichtung stehen dem Monteur dann nur Drehbewegungen des Anbohrsattels um die Längsachse des Hauptverteilerrohres zur Verfügung, wodurch sich aber das angestrebte Fluchten von Hausanschluß-Leitung mit dem Abzweig rohrstück nur im kaum gegebenen Idealfall erreichen läßt, daß die Hausanschluß-Leitung in exakt radialer Richtung an das Hauptverteilerrohr heranläuft.When connecting the branch pipe piece with the running house connection line often occur assembly technology Difficulties, especially if the house short lines to the head at different angles run up the distributor pipe. The fitter is in alignment then only rotary movements of the tapping saddle around the longitudinal axis of the main manifold available, but that desired alignment of the house connection line with the branch pipe piece can only achieve in the rarely given ideal case that the house connection line in the exact radial direction to the Main manifold runs up.
Der Erfindung liegt die Aufgabe zugrunde, ein Verbindungs formstück dahingehend zu ver bessern, daß die Ausrichtung an heranlaufende Hausanschluß-Lei tungen erleichtert wird. The invention has for its object a connection fitting to ver improve the alignment with approaching house connection lei is facilitated.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß am Sattelkörper im durch das Anbohrloch vorgegebenen Ansetzbe reich des Abzweigrohrstückes eine die Ausmündung des Anbohr loches flanschartig umgebende Plattform ausgeformt ist, daß ein Ende des Abzweigrohrstückes einen Radialflansch aufweist und daß zwischen Plattform und Radialflansch ein zweites elektrisches Schweißelement bestehend aus thermoplatischen Kunststoff und Widerstandsdraht angeordnet ist.This object is achieved in that on Saddle body in the attachment area specified by the tapping hole range of the branch pipe a the mouth of the tapping hole surrounding flange-shaped platform is formed that one end of the branch pipe piece has a radial flange and that between the platform and radial flange a second electrical welding element consisting of thermoplastic Plastic and resistance wire is arranged.
Um eine Anpassung an die heranlaufende Hausanschluß-Lei tung zu erreichen, kann das erfindungsgemäße Verbindungsform stück einmal um 360° um die Achse des Hauptverteilerrohres be wegt werden, indem der Sattelkörper auf der äußeren Oberfläche des Hauptverteilerrohres entsprechend verschoben wird. Darüber hinaus kann das Abzweigrohrstück, welches mit seinem Radial flansch an der Plattform anliegt, ebenfalls um 360° um eine durch das Zentrum des Anbohrloches verlaufende Achse gedreht werden, die radial zur Längsachse des Hauptverteilerrohres ver läuft. Desweiteren kann das Sattelstück auch längs der Rohr leitung verschoben werden. Damit ist eine Anpassung an unter schiedlich heranlaufende Hausanschluß-Leitungen in verbesser ter Weise mit drei Freiheitsgraden möglich.To adapt to the approaching house connection line device can achieve the connection form according to the invention piece by 360 ° around the axis of the main manifold be moved away by the saddle body on the outer surface of the main distributor pipe is shifted accordingly. About that In addition, the branch pipe piece, which with its radial flange on the platform, also by 360 ° by one axis running through the center of the tapping hole are the ver radially to the longitudinal axis of the main manifold running. Furthermore, the saddle piece can also be along the tube line to be moved. This is an adjustment to under differently approaching house connection lines in improvements ter possible with three degrees of freedom.
Nach entsprechender Ausrichtung sowohl des Sattelkörpers als auch des Abzweigrohrstückes kann eine Verschweißung zwi schen Radialflansch des Abzweigrohrstückes und der Plattform des Sattelkörpers mittels des zweiten Schweißelements er folgen. Durch die Verschweißung ist das ausgerichtete Ab zweigrohrstück mit dem Sattelkörper fest verbunden. After appropriate alignment of both the saddle body and the branch pipe piece, a weld between radial flange of the branch pipe section and the platform the saddle body by means of the second welding element consequences. The aligned Ab is due to the welding branch pipe piece firmly connected to the saddle body.
Sattelkörper und Abzweigrohrstück können formschlüssig ge fügt sein, wobei das Abzweigrohrstück um die Abzweigrohrstück achse drehbar ist. Dazu kann eine Schnappverbindung vorgesehen sein, die eine erleichterte Handhabung und einen Schweißvor gang begünstigt.Saddle body and branch pipe section can be form-fitting inserts, with the branch pipe piece around the branch pipe piece axis is rotatable. A snap connection can be provided for this be easier handling and welding favored gear.
Um das Zusammenfügen von Sattelkörper, Heizelement und Ab zweigrohrstück zu erleichtern, weist die freie Oberfläche der Plattform eine Vertiefung auf. In der Vertiefung kann das zweite Schweißelement angebracht werden. Vorzugsweise ist das Schweißelement eine in die Vertiefung eingelegte, mit Wider standsdraht bewickelte Scheibe, deren Scheibenkern aus einem Werkstoff besteht, der sich beim Schmelzen mit dem Werkstoff von Plattform und Radialflansch verbindet. Dabei ist die Vertiefung kreisförmig und auch die Plattform kann kreisförmigen Umriß aufweisen. In eine derartige Vertiefung ist die Scheibe nahezu bündig versenkbar. Mit besonderem Vorteil ist die Tiefe der Vertiefung größer als die Dicke der Scheibe. Dadurch bildet der Rand der Vertiefung eine umlaufende, leicht erhöhte Schulter, die dann, wenn der Ra dialflansch entsprechenden Durchmesser aufweist, einer Zen trierung des Radialflansches gegenüber der Plattform dient, die das Ausrichten und Zusammenfügen der Teile unmittelbar vor ihrem Verschweißen erleichtert. Selbstverständlich können Ra dialflansch und Plattform mit Vertiefung auch andere Umrißfor men aufweisen, die es ermöglichen, den Radialflansch passend in die Vertiefung einzusetzen. An den Rand der Vertiefung können Rastelemente für eine Schnappverbindung angeformt sein.To assemble the saddle body, heating element and Ab The free surface of the Platform a deepening. In the deepening it can second welding element can be attached. Preferably that is Welding element inserted into the recess, with contr wire wrapped disc, the disc core of one Material exists, which is when melting with the material of platform and radial flange connects. Here is the Deepening circular and also the platform can have circular outline. In such a deepening the pane is retractable almost flush. With special The depth of the recess is greater than the thickness of the advantage Disc. As a result, the edge of the depression forms a circumferential, slightly raised shoulder, which is then when the Ra Dialflansch has appropriate diameter, a Zen serving the radial flange opposite the platform, the alignment and assembly of the parts immediately before their welding easier. Of course, Ra dial flange and platform with recess also other outline shape Men have, which make it possible to fit the radial flange insert into the recess. To the edge of the depression can molded locking elements for a snap connection be.
