Abstract

Feed channels are formed in a continuous strand or bar of foamed synthetic material, the channel walls of which are densified so that they are water tight. At the same time, the channels are spaced out sufficiently to ensure adequate heat insulation, when the strands are assembled into a hot and cold water circulating system. The strands with the channels in them are formed by extrusion, and the outer walls of the strands are also densified. Provides a distributing system for hot and cold water which does not require individual erection of pipes and their subsequent insulation. The strands can be installed easily since they can be drilled at any convenient point.

Description

Verfahren zur Herstellung eines Ver- Process for the production of a

teilungsstranges für Warm- und Kaltwasserleitungen Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines mehrere Leitungskanäle enthaltenden Verteilungsstranges für War- und Kaltwasserleitungen. dividing line for hot and cold water pipes The invention relates to a method of making one containing multiple conduits Distribution line for hot and cold water pipes.

Zur Installation von Warm- und Kaltwasserleitungen werden diese in jeweiligen Abständen voneinander zu einem Verteilungsstrang zusammengefaßt verlegt. Die bekannten Verteilungsstränge dieser Art bestehen aus gesonderten Rohren und Formstücken, die in üblicher Weise aus metallenen Werkstoffen oder aus Kunststoffen gefertigt sind. Bei solchen Verteilungssträngen werden die einzelnen Rohre und Formstücke nachträglich mit einer geeigneten Wärmeisolierung versehen und mUssen außerdem mit dieser Isolierung Jeweils gesondert in den Jeweiligen Verlegungsstrecken montiert und gehalten werden. Die gesonderte Herstellung und Verlegung von Rohren und Formstücken, die nachträgliche Wärmeisolierung sowie die gesonderte Halterung und Befestigung führen zu einem verhältnismäßig hohen Fertigungs-, Teile- und insbesondere Arbeitsaufwand an der Baustelle. For the installation of hot and cold water pipes, these are used in respective distances from each other combined to form a distribution line. The known distribution lines of this type consist of separate pipes and Fittings made in the usual way from metallic materials or from plastics are made. In such distribution lines, the individual pipes and fittings retrospectively provided with suitable thermal insulation and must also be provided with of this insulation, each mounted separately in the respective laying sections and be held. The separate production and laying of pipes and fittings, the subsequent thermal insulation as well as the separate mounting and fastening lead to a relatively high production, parts and, in particular, workload at the construction site.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Verteilungsstrangs der eingangs angegebenen Art zu schaffen, bei dem die Verwendung gesonderter Rohre und Formstücke sowie Jede nachträgliche Wärmeisolierung vermieden wird und die Installation sowie Halterung entscheidend vereinfacht werden. Dies wird nach der Erfindung dadurch erreicht, daß die Leitungskanäle unmittelbar mit einem strangförmigen Grundkörper aus Schaumkunststoff unter Verdichtung der Kanalwandungen zur Wasserdichtheit in dem für die Wärmedämmung erforderlichen Abstand voneinander geformt werden. The invention is based on the object of a method for production to create a distribution strand of the type specified at the outset, in which the use separate pipes and fittings as well as any subsequent thermal insulation avoided and the installation and mounting are significantly simplified. this is achieved according to the invention in that the line channels directly with a strand-shaped Base body made of foam plastic with compression the duct walls for watertightness in the area required for thermal insulation Distance from each other.

Auf diese Weise wird der isolierende Schaumkunststoff selbst als Rohrwerkstoff verwendet. Ein einziger strangförmiger Grundkörper bildet sämtliche Leitungskanäle selbst, so daß die Verwendung gesonderter Rohre und Formstücke ganz vermieden wird und eine gesonderte, insbesondere nachträgliche Isolierung der Leitungskanäle entbehrlich wird. Der sämtliche Leitungskanäle selbst enthaltende strangförmige Grundkörper kann aus dem Schaumkunststoff einerseits kontinuierlich einfach gefertigt werden und ferner als integriertes Bauteil installiert, insbesondere montiert und befestigt werden. Eine besonders einfache Herstellung des strangförmigen Grundkörpers ergibt sich in weiterer Ausgestaltung der Erfindung, wenn dieser mit den Leitungskanälen extrudiert wird. Bei der Herstellung des strangförmigen Grundkörpers können dessen Abmessungen derart gewählt werden, daß auch die jeweils erforderliche Wärmedämmung nach außen gewährleitstet ist. Ein wesentlicher Vorteil ist ferner darin zu sehen, daß der erfindungsgemäß hergestellte Verteilungsstrang bzw. seine Leitungskanäle bauseits an beliebiger Stelle und mit jeweils geeigneter Bemessung angebohrt werden können, um insbesondere Anschluß- oder Verbindungsöffnungen zu bilden.In this way, the insulating foam plastic itself is used as a pipe material used. A single strand-like base body forms all of the line channels itself, so that the use of separate pipes and fittings is completely avoided and a separate, in particular subsequent insulation of the ducts is dispensable will. The strand-like base body containing all the ducts itself can on the one hand be continuously and easily manufactured from the foam plastic and also installed as an integrated component, in particular assembled and fastened will. A particularly simple production of the strand-like base body results in a further embodiment of the invention, when this with the line channels is extruded. In the production of the strand-like base body can be Dimensions are chosen so that the thermal insulation required in each case is guaranteed to the outside. Another major advantage is that that the distribution line produced according to the invention or its ducts Drilled on site at any point and with a suitable dimensioning in each case can, in particular to form connection or connection openings.

Zweckmäßig wird in weiterer Ausgestaltung der Erfindung auch die Außenwandung des strangförmigen Grundkörpers verdichtet, um ihm so eine Jeweils gewUnschte äußere Festigkeit gegen Beschädigung und Verschleiß zu geben. In a further embodiment of the invention, the Outer wall of the strand-like base body is compressed to give it a respective one To give the desired external strength against damage and wear.

Nach einer weiteren Ausführungsform der Erfindung wird der strangförmige Grundkörper durch Koextrusion wenigstens zweier, Jeweils einen Umfangsabschnitt der Leitungskanäle enthaltender Teilstränge geformt, die an den einander zugeordneten Flächen zum Grundkörper miteinander verbunden werden. Diese Verfahrensweise eignet sich besonders gut für die Formung aus dem Schaumkunststoff unter gleichzeitiger Verdichtung der Jeweiligen Wandungen. According to a further embodiment of the invention, the strand-shaped Base body by coextrusion of at least two, each one circumferential section formed of the conduit containing sub-strands, which are attached to the associated Surfaces are connected to one another to form the base body. This procedure is suitable particularly good for shaping from the foam plastic while at the same time Compaction of the respective walls.

Die Verwindung der Teilstränge kann entweder bereits kontinuierlich anschließend an die Koextrusion durch Ver- schweißung infolge Wärmewirkung erfolgen, oder es können die Teilstränge durch geeignete Verklebe- oder Verschweißvorgänge miteinander verbunden werden.The twisting of the partial strands can either already be continuous subsequent to the coextrusion by means of welding due to the effect of heat or the partial strands can be made by suitable gluing or welding processes be connected to each other.

Als besonders zweckmäßig hat es sich erwiesen, wenn der strangförmige Grundkörper bzw. die Teilstränge aus kristallinem Thermoplast geformt werden. Es ist aber auch möglich, den strangförmigen Grundkörper bzw. die Teilstränge aus duromerem Kunststoff zu formen. It has proven to be particularly useful if the strand-shaped Base body or the partial strands are formed from crystalline thermoplastic. It but it is also possible to use the strand-like base body or the sub-strands made of duromer Molding plastic.

Falls für die Jeweiligen Anwendungsfälle eine erhöhte Festigkeit des Verteilungsstranges gewünscht wird, können in weiterer Ausgestaltung der Erfindung in den strangförmigen Grundkörper bzw. in die Teilstränge Faserverstärkungen eingeformt werden. If there is an increased strength for the respective application of the distribution line is desired, can in a further embodiment of the invention molded fiber reinforcements into the strand-like base body or into the partial strands will.
