Abstract

Es wird ein Baustein mit einer Vielzahl von inneren Hohlräumen vorgeschlagen, die den Baustein durchsetzen und mit Stegen, welche die Hohlräume trennen. Erfindungsgemäß ist wenigstens ein Steg im Bausteininnern ein- oder mehrfach unterbrochen. Eine weitere erfindungsgemäße Lösung sieht einen Baustein zur Wärmedämmung vor, der eine Vielzahl von Hohlräumen aufweist, die parallel zur Bausteinauflagefläche einen Querschnitt besitzen, dessen Längsausdehnung im Verhältnis zur Breitenausdehnung größer 2:1 ist, wobei die Längsausdehnung quer zur Wärmeflußrichtung orientiert ist, und wobei in den Hohlräumen in Wärmeflußrichtung kurze die Hohlraumwandungen verbindende Stegabschnitte vorgesehen sind. Bei einem Verfahren zur Herstellung derartiger Bausteine mittels extrudieren durch ein Mundstück werden zur Erzeugung von unterschiedlichen Lochbildern während des Extrudierens Durchlaßquerschnitte druckseitig im Mundstück zeitweise verschlossen. Schließlich wird eine Vorrichtung zur Herstellung von solchen Bausteinen vorgeschlagen, bei welcher Zwischenräume zwischen den Kernen wenigstens über einen Teil der Länge der Kerne in Extrudierrichtung im Druckbereich des Mundstücks verschließbar sind.

Figure 00000001
A module is proposed with a large number of internal cavities which penetrate the module and with webs which separate the cavities. According to the invention, at least one web in the interior of the module is interrupted one or more times. Another solution according to the invention provides a building block for thermal insulation which has a large number of cavities which have a cross section parallel to the building block contact surface, the longitudinal extent of which is greater than 2: 1 in relation to the latitude, the longitudinal extent being oriented transversely to the direction of heat flow, and in short web sections connecting the cavity walls are provided in the cavities in the heat flow direction. In a method for producing such building blocks by means of extrusion through a mouthpiece, passage cross sections are temporarily closed on the pressure side in the mouthpiece in order to produce different hole patterns during the extrusion. Finally, a device for producing such building blocks is proposed, in which spaces between the cores can be closed at least over part of the length of the cores in the extrusion direction in the pressure region of the mouthpiece.
