Description
Die Erfindung betrifft eine Verbindung von Gußrohren, - Gußrohrteilstücken oder Formstücken durch Schweißung oder Lötung von in die Stoßstellen eingegossenen Verbindungsstücken aus schweiß- oder lötfähigem Metalt. Zur Herbeiführung dieser Verbindung werden die Verbindungsstücke bereits beim Gießen der Rohre, Teil- oder Formstücke mit eingegossen. Hierzu werden in die Formen für die erwähnten Gußstücke, nach den Enden zu, Ringe aus Schmiedeeisen oder Stahl eingelegt, so daß diese zum Teil freiliegen und etwas die Stirnkanten der gegossenen Stücke überragen oder mindestens bündig mit ihnen abschneiden. Dabei können die Verbindungsstücke als innere Auskleidung der Gußstückenden oder aber in die — gegebenenfalls verstärkte — Wandung der Gußstücke hineinverlegt sein.The invention relates to a connection of cast iron pipes, cast pipe sections or fittings by welding or soldering connecting pieces cast into the joints Made of weldable or solderable metal. To bring about this connection will be the connecting pieces with the casting of the pipes, parts or fittings poured. For this purpose, in the forms for the mentioned castings, after the ends to, rings made of wrought iron or steel inserted so that these are partially exposed and slightly protrude from the front edges of the cast pieces or at least flush with them cut off. The connecting pieces can be used as the inner lining of the casting ends or in the - possibly reinforced - wall of the castings be.
An Hand einer Zeichnung soll die Verbindung näher erläutert werden.The connection is to be explained in more detail using a drawing.
Beim Herstellen der Formen für die Gußrohre« (Abb. 1) werden in den vom Kern freigelassenen Raum am Ende der Form Ringstücke b aus Schmeideeisen oder Stahl eingelegt und der Ringraum erweitert. Die Ringstücke b1 können auch derart eingebracht werden, daß sie eine glatte Fortsetzung der Innenwand der Rohre α bilden und derem Stirnflächen überragen (Abb. 2). Die Stirnflächen der Rohre können abgesetzt sein, jedenfalls müssen die Ringstücke b mit ihrer Außenseite auf einem Teil ihrer Länge freiliegen, um für die Schweißung oder Lötung gut zugänglich zu sein. Zu deren Vorbereitungen werden die Stoßflächen der Ringstücke glatt abgedreht.When making the molds for the cast iron pipes (Fig. 1), ring pieces b made of wrought iron or steel are inserted into the space left free by the core at the end of the mold, and the annular space is expanded. The ring pieces b 1 can also be introduced in such a way that they form a smooth continuation of the inner wall of the tubes α and protrude beyond their end faces (Fig. 2). The end faces of the tubes can be offset, in any case the outer side of the ring pieces b must be exposed over part of their length in order to be easily accessible for welding or soldering. In preparation for this, the joint surfaces of the ring pieces are turned off smooth.
