Description
Rohrförmiger Körper aus elastomerem Werkstoff mit eingebetteten stückigen Füllkörpern Bekanntlich werden in letzter Zeit in immer größerem Umfang Abflußrohre kleiner Querschnittsfläche aus PVC und anderen modernen Kunststoffen hergestellt. Bei diesen Rohren spielt die Wandstärke und die Tatsache, daß sie nur in Gebäuden verlegt werden, für die Stabilität zunächst keine Rolle.Tubular body made of elastomeric material with embedded lumpy Packing bodies It is well known that drainage pipes are becoming increasingly popular in recent times small cross-sectional area made of PVC and other modern plastics. The wall thickness and the fact that they are only used in buildings play a role in these pipes are laid, initially irrelevant for the stability.
Anders ist es aber, wenn derartige Rohre mit großen Querschnittsflächen innerhalb des Erdreiches und besonders unter Straßendecken usw. verlegt werden. Hierbei muß die Wandstärke entsprechend stark ausgeführt werden, um eine genügende Stabilität des verlegten Rohres zu gewährleisten. Mit den heutigen Mitteln ist es selbstverständlich möglich, starkwandige Rohre jeder beliebigen Länge herzustellen, jedoch sind die Kosten für den dabei aufzuwendenden Rohstoff beträchtlich.But it is different when such pipes with large cross-sectional areas be laid within the ground and especially under road surfaces, etc. Here, the wall thickness must be made correspondingly strong in order to achieve a sufficient To ensure the stability of the laid pipe. With today's means it is of course, it is possible to manufacture thick-walled pipes of any length, however, the cost of the raw material involved is considerable.
Es sind bereits rohrförmige Körper bekannt, deren elastomerem Werkstoff stückige Füllkörper gleicher Oberflächenbeschaffenheit und Bindeeigenschaft beigemischt sind, um bestimmte Eigenschaften, z. B. Erhöhung der Wärmedämmung, zu erzielen. Bei rohrförmigen Körpern aus hydraulisch abbindenden Stoffen ist es auch schon bekannt, dem Rohrwandwerkstoff stüekige Füllkörper zur Erhöhung der Druckfestigkeit beizumischen.There are already known tubular bodies, their elastomeric material Lumpy fillers with the same surface properties and binding properties are added are to achieve certain properties, e.g. B. Increase in thermal insulation to achieve. In the case of tubular bodies made of hydraulically setting substances, it is already known Mix in the pipe wall material stüekige packing to increase the compressive strength.
In Anlehnung an diesen Grundgedanken wird zur Erzielung eines gegen Außendruck festen Kunststoffrohres erfindungsgemäß vorgeschlagen, daß der elastomere Rohrwandwerkstoff ein Kunststoff, z. B. PVC, ist und die Füllkörper aus natürlichem oder künstlichem keramischem Werkstoff bestehen.Based on this basic idea, to achieve a counter External pressure fixed plastic pipe proposed according to the invention that the elastomeric Pipe wall material a plastic, e.g. B. PVC, and the packing is made of natural or artificial ceramic material.
Ein solcher Rohrwandaufbau bietet eine genügende Stabilität, wobei die Füllkörper als statisch tragendes Gerüst in der Kombination von Kunststoff und Keramik dienen.Such a pipe wall structure offers sufficient stability, with the packing as a static load-bearing structure in the combination of plastic and Serving pottery.
Zum Herstellen derartiger Rohre, beispielsweise als Ersatz von Steinzeugrohren, die wegen ihres hohen Gewichtes nur in beschränkter Rohrlänge hergestellt werden können, wird vorgeschlagen, daß eine vorgefertigte Stahlform mit keramischen Körpern, vorzugsweise mit Blähton oder ähnlichen künstlich hergestellten Körpern gefüllt wird. Diese keramischen Komponenten haben alle eine gleiche Oberflächenbeschaffenheit und somit eine gleiche Bindeeigenschaft gegenüber dem Kunststoff, der nun in diese Form auf der einen Seite hineingedrückt wird, wenn beispielsweise die Form selbst unter Vakuum steht. Nach dem Abbindeprozeß des plastischen Kunststoffbinders wird die Stahlform geöffnet und das fertige Rohr herausgenommen.For the production of such pipes, for example as a replacement for clay pipes, which, because of their high weight, are only manufactured in a limited tube length can, it is proposed that a prefabricated steel mold with ceramic bodies, preferably filled with expanded clay or similar man-made bodies will. These ceramic components all have the same surface finish and thus the same binding property compared to the plastic that is now in this Form is pressed in on one side, for example if the form itself is under vacuum. After the setting process of the plastic plastic binder opened the steel mold and took out the finished tube.
Der keramische Rohstoff, insbesondere wenn es sich dabei um Blähton handelt, weist weiterhin die Eigenschaft auf, daß er besonders leicht ist, wodurch das Transportgewicht des erfindungsgemäßen Rohres und dessen Handhabung beim Verlegen erleichtert werden.The ceramic raw material, especially if it is expanded clay acts, also has the property that it is particularly light, whereby the transport weight of the pipe according to the invention and its handling when laying be relieved.
