Description
Die Erfindung betrifft eine zementgebundene Mischung zur Herstellung eines Niederspannungs-Heizestrichs und eines Bauelementes daraus.The invention relates to a cementitious mixture for producing a low-voltage Heizestrichs and a component thereof.
Es ist bekannt eine Heizestrichmischung aus Zuschlagstoffen (Sand, Splitt) oder Fasern aus textil, PE, AR-Glas zur statischen Stabilisierung und Rissminderung herzustellen. Diese Heizestriche enthalten Heizelemente aus Warmwasserrohren oder elektrischen Normalspannungsheizelementen, welche Wärmeenergie in den Estrich eintragen, welcher wiederum über seine große Bodenfläche diese an die Umgebungsluft abgibt. Der Wirkungsgrad ist dabei gering. Dieser Warmwasser-Heizestrich ist im Außenbereich nicht einsetzbar, da durch Bodenfröste das System zerstört wird.It is known to produce a Heizstrichmischung of aggregates (sand, grit) or fibers of textile, PE, AR glass for static stabilization and crack reduction. These heated screeds contain heating elements from hot water pipes or electrical normal voltage heating elements, which enter heat energy into the screed, which in turn emits their large floor surface to the ambient air. The efficiency is low. This hot-water heating screed is not suitable for outdoor use, since ground frosts destroy the system.
Es ist auch bekannt, Fasern in Beton oder Estrich einzumischen, wobei die dort verwendeten Fasern zur Erhöhung der Biegezugfestigkeit bzw. Risssicherung und Stabilität beitragen sollen, nicht aber elektrisch leitend sind.It is also known to mix fibers in concrete or screed, with the fibers used there to contribute to increasing the flexural strength or crack resistance and stability, but are not electrically conductive.
Es ist auch bekannt, elektrische Heizdrähte in Beton oder Estrich einzuarbeiten, die mit mindestens 220 V betrieben werden.It is also known to incorporate electrical heating wires in concrete or screed, which are operated with at least 220 V.
Diese Lösungen haben den Nachteil, dass sie aus Sicherheitsgründen, ohne aufwändige Zusatzmaßnahmen, nicht für außen angewendet werden können, z. B. große Konstruktionsdicken haben, sehr reaktionsträge sind und wegen der Beheizung voluminöser anderer Bauteile sowie ungleichmäßiger Verteilung der Heizelemente einen geringen Wirkungsgrad haben.These solutions have the disadvantage that they can not be applied externally for safety reasons, without expensive additional measures, eg. B. have large structural thicknesses, are very slow to react and because of the heating of voluminous other components and uneven distribution of the heating elements have a low efficiency.
Als Flächenheizung, insbesondere Wand- und Fußbodenheizung, kommt derzeit neben einer Warmwasserheizung, wobei entlang der betreffenden Fläche Rohre verlegt sind, vorzugsweise in Mäandern, durch welche ein flüssiges Heizmedium, insbesondere warmes Wasser, zirkuliert, auch eine Elektroheizung in Betracht, wobei ein Widerstandsdraht, z. B. aus Konstanten, auf die zu beheizende Fläche aufgebracht wird. Während des Betriebs wird dann von einer äußeren Spannung ein Strom durch diesen Widerstandsdraht getrieben, welcher den Draht erwärmt. Beide Systeme haben Nachteile. Der größte liegt darin, dass man von außen, d. h., an der fertigen Wand, Boden oder dgl., nicht erkennen kann, wo genau die Heizrohre bzw. der Heizdraht verläuft. Dies kann insbesondere bei Heizrohren aus Kunststoff, gerade aber auch bei Heizdrähten, zu einem großen Problem führen, wenn nachträglich bauliche Veränderungen vorzunehmen sind. Hier kann schon das Einschlagen eines Nagels an einer falschen Stelle fatale Folgen haben: Ein versehentlich perforiertes Heißwasserrohr wird undicht, die Flüssigkeit tritt in das umliegende Bau-, insbesondere Mauerwerk aus und durchfeuchtet dieses, Flecken- und Schimmelbildung ist nur eine mögliche Folge. Andererseits kann durch einen falsch eingeschlagenen Nagel auch ein Widerstand durchtrennt werden. Damit wird nicht nur ein ganzer Widerstandsstrang und damit ein großer Abschnitt der Flächenheizung stillgelegt, sondern es besteht überdies sogar die Gefahr eines elektrisierenden Stromschlages, beispielsweise an einem metallischen Nagel, der in elektrischen Kontakt zu dem Widerstandsdraht tritt, insbesondere wenn gleichzeitig der Stromkreis unterbrochen ist und der gesamt Heizstrom über eine Person abfließt.As underfloor heating, in particular wall and floor heating, is currently next to a hot water heater, along the surface concerned pipes are laid, preferably in meanders through which a liquid heating medium, especially warm water, circulating, also an electric heater into consideration, with a resistance wire, z. B. from constants, is applied to the surface to be heated. During operation, current is then driven by an external voltage through this resistance wire, which heats the wire. Both systems have disadvantages. The biggest is that from the outside, d. h., On the finished wall, floor or the like., Can not see exactly where the heating pipes or the heating wire runs. This can lead to a big problem, especially in heating pipes made of plastic, but especially in heating wires, if subsequently be made structural changes. Here, even the hammering in of a nail in a wrong place can have fatal consequences: A hot water pipe that has been perforated by mistake will leak, the liquid will leak out into the surrounding building, in particular masonry and dampens it. Stain and mold formation is only one possible consequence. On the other hand, it is also possible to cut through a resistance by means of a wrongly nail. This not only a whole resistance strand and thus a large portion of the surface heating is shut down, but there is even the risk of an electric shock, for example on a metallic nail, which comes into electrical contact with the resistance wire, especially if at the same time the circuit is interrupted and the total heating current flows over one person.
