Description
Die Erfindung betrifft einen Baustein mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen sowie ein entsprechendes Verfahren zu dessen Herstellung.The The invention relates to a module with in the preamble of claim 1 specified characteristics and a corresponding method to its Production.
Zum Hintergrund der Erfindung ist festzuhalten, dass aus dem Stand der Technik seit langem bekannt ist, Bausteine mit einem ein Lochbild aus Hohlräumen aufweisenden, statisch tragenden Basiskörper beispielsweise aus einem Ton- oder Kalksandstein-Material auszubilden. Die durch die Hohlräume gebildete Luftkammern erhöhen die Wärmedämmfähigkeit des Bausteins. Seit geraumer Zeit ist nun die Fachwelt bestrebt, die Wärmedämmfähigkeit von Baumaterialien aus Energiespargründen zu optimieren. In diesem Zusammenhang sind z. B. aus dem Firmenprospekt „calinoor® Tragmauerwerk mit integrierter Wärmedämmung...” der Anmelderin bereits Lochsteine bekannt, deren Hohlräume mit hoch-wärmedämmfähigen Füllungen, wie beispielsweise Polystyrol-Formkörpern verschlossen sind.The background of the invention is to be noted that has long been known from the prior art, building blocks with a hole pattern of cavities having, statically supporting base body, for example, from a clay or sand-lime brick material. The air chambers formed by the cavities increase the thermal insulation of the device. For some time now, the professional world is anxious to optimize the thermal insulation of building materials for energy saving reasons. In this context, z. B. from the company brochure "calinoor ® Tragmauerwerk with integrated insulation ..." the Applicant already known bricks, the cavities are closed with highly-heat-insulating fillings, such as polystyrene moldings.
Eine Alternative hierzu ist das direkte Einfüllen von Mineralschaumbeton in die Hohlräume, was auf Grund der geringeren Materialkosten und rationelleren Fertigungsweise eine erstrebenswerte Löschung darstellt.A Alternative to this is the direct filling of mineral foam concrete into the cavities, due to the lower material costs and more rational way of production a desirable deletion represents.
Im Zuge der erstrebten hohen Dämmwirkung und guten Befüllbarkeit der Hohlräume ist nun versucht worden, sehr dünnflüssige Schaumbetone mit einem hohen Porosierungsgrad zu verwenden. Dabei hat sich als Problem herausgestellt, dass die Basiskörper üblicher Bausteine etwa aus Ziegel oder Kalksandstein kapillarwirkend sind, was an sich aus wohnklimatischen Gründen erwünscht ist. In Hinsicht auf die Schaumbetonfüllung hat diese jedoch den Nachteil, dass das für die Stabilität des frisch eingebrachten Schaummaterials notwendige Wasser nach der Verfüllung in den saugenden Basiskörper abgezogen wird. Dies wiederum hat die Folge, dass das Schaumbetonmaterial destabilisiert wird und in sich zusammensackt.in the Course of the desired high insulation effect and good fillability the cavities has now been tried, very thin foam concrete to use with a high degree of porosity. It has as Problem highlighted that the base body of ordinary building blocks about Brick or sand-lime brick are kapillarwirkend, which in itself from living-climatic establish he wishes is. With regard to the foam concrete filling, however, this has the disadvantage that for the stability the freshly introduced foam material necessary water after the backfilling in the absorbent base body is deducted. This in turn has the consequence that the foam concrete material is destabilized and collapses.
Zur Abhilfe wurde bereits versucht, den Basiskörper gründlich vorzunässen, was jedoch keinen Erfolg brachte. Im Gegenteil: Es ist davon auszugehen, dass der Kapillarfluss im vorgenässten Stein direkt an den Kapillarfluss des aussedimentierenden Wassers des Schaums anbindet.to Remedy has already been attempted to thoroughly wet the base body, which but did not bring success. On the contrary: it can be assumed that the capillary flow in vorgenässten Stone directly to the capillary flow of the sedimenting water of the foam binds.
Ausgehend von der geschilderten Problematik liegt der Erfindung die Aufgabe zu Grunde, einen Baustein und ein Verfahren zu dessen Herstellung anzugeben, bei dem ein Verfüllen des Lochbildes mit einer stark porosierten Schaumbetonfüllung zur Bildung eines hochwärmedämmenden Bausteines ermöglicht wird.outgoing From the described problem of the invention is the task to provide a building block and a method of making it, when filling a the hole pattern with a highly porous foam concrete filling for Formation of a high thermal insulation Blocks enabled becomes.
Diese Aufgabe wird durch die im Kennzeichnungsteil des Anspruches 1 bzw. 5 angegebenen Merkmale gelöst. Kern der Erfindung ist eine wasserabweisende Sperrschicht zwischen der Schaumbetonfüllung und der die Hohlräume begrenzenden Wandung des Basiskörpers. Mit Hilfe dieser Sperrschicht wird der für den Schaumbeton destabilisierende Kapillarwasserabfluss unterbunden. Die Schaumbetonfüllung kann damit ohne Destabilisierung aushärten und behält damit ihre spezifikationsgemäße hohe Porosität.These The object is achieved by the in the characterizing part of claim 1 or 5 specified characteristics solved. Core of the invention is a water-repellent barrier layer between the foamed concrete filling and the cavities limiting wall of the base body. With the help of this barrier layer is destabilizing for the foam concrete Kapillarwasserabfluss prevented. The foam concrete filling can so that they harden without destabilization and keeps so that their specification high Porosity.
Die Sperrschicht selbst kann als hydrophobe Beschichtung vorzugsweise einer Silikonöl-Suspension oder einem pflanzlichen Öl, als wasserabweisende Dispersionsbeschichtung oder durch eine Folienbeschichtung gebildet sein.The The barrier layer itself may preferably be used as the hydrophobic coating a silicone oil suspension or a vegetable oil, as a water-repellent dispersion coating or by a film coating be formed.
