Description
Verfahren zum Ausschäumen von Hohlräumen Process for filling cavities with foam
in Mauersteinen Die Erfindung betrifft ein Verfahren zum Ausschäumen von Hohlräumen in Mauersteinen zur Verbesserung des Wärmeschutzes für Gebäude. in bricks The invention relates to a method for foaming of cavities in bricks to improve thermal insulation for buildings.
Bei allen gebräuchlichen Baustoffen läßt sich zwar die Wärmedämmfähigkeit erhöhen durch Herabsetzen des spezifischen Gewichts jedoch nicht, ohne auch gleichzeitig die Druckfestigkeit in vielen Fällen erheblich zu vermindern. Die verminderte Druckfestigkeit schränkt die Verwendung der wärmedämmtechnisch verbesserten Baustoffe in tragenden Bauteilen, z.B. als tragende Außenwand stark ein oder schließt sie sogar ganz aus. Dies führt zu einer unwirtschaftlichen Vielzahl von Baustoffen. Ein vielseitig einsetzbarer Baustoff muß daher eine gute Wäriedämmung mit ausreichend hoher Druckfestigkeit verbinden. With all common building materials, the thermal insulation properties however, do not increase by reducing the specific gravity, without also at the same time to reduce the compressive strength considerably in many cases. The reduced compressive strength restricts the use of the thermally improved building materials in load-bearing Components, e.g. as a load-bearing outer wall, or even exclude them entirely. This leads to an uneconomical large number of building materials. A versatile one Building material must therefore have good thermal insulation with sufficiently high compressive strength associate.
Bekannt ist ein in der Schweiz in größerem Maßstab eingesetztes Thermo-Modul-Mauerwerk. Dabei werden Mauerziegel im Werk durch Verkleben mit Polystyrolschaumplatten zu Sandwichelementen verbunden. A thermal module masonry used on a larger scale in Switzerland is known. Bricks are closed in the factory by gluing them with expanded polystyrene panels Sandwich panels connected.
Auf der Baustelle wird dieses Element mit normalen Mauerziegeln im Verband zu einem hochtragfesten, aber auch mit hoher Wärmedämmung ausgerüstetem Mauerwerk verarbeitet.On the construction site, this element is installed with normal bricks in the Association to a high load-bearing capacity, but also with high thermal insulation equipped Masonry processed.
Weiterhin sind bekannt, Betonsteine die im Prinzip aus einer Außenschale und einer Innenschale bestehen, welche durch einen oder mehrere Stege so miteinander verbunden sind, daß zwischen den Schalen ein Luftraum entsteht. Dieser Luftzwischenraum wird anschließend mit einer wärmedämmenden Platte, meist Polystyrolschaum, ausgefüllt. Furthermore, concrete blocks are known, which in principle consist of an outer shell and an inner shell, which by one or more webs so with each other are connected that an air space is created between the shells. This air gap is then filled with a heat-insulating board, usually polystyrene foam.
Die beiden genannten Verfahren haben mindestens zwei gravierende Nachteile: Die kombinierten Steine können nur unter hohem Aufwand volimechanisch hergestellt werden, Darüberhinaus ergibt die eingesetzte Polystyrolschaumschicht im Vergleich zum tragenden Baustoff eine bauphysikalisch unerwUnschte Diffusionssperre. Die Folgen können Durchfeuchtungserscheinungen und Abbau der wärmedämmenden Eigenschaften der Isolierschicht sein. Bei den durch Stege verbundenen Konstruktionen ist punktuell Uber den einzelnen Steg der Transport von Raumfeuchte nach außen möglich, quantitativ reichen die Querschnitte weniger Stege erfahrungsgemäß nicht aus, um ein neu bezogenes Bauvorhaben von innen nach außen austrocknen zu lassen und zusätzlich die wohnbedingte Feuchte nach außen abzuführen. The two procedures mentioned have at least two serious ones Disadvantages: The combined stones can only be fully mechanically implemented with great effort In addition, the polystyrene foam layer used results A diffusion barrier that is undesirable in terms of building physics compared to the load-bearing building material. The consequences can be signs of moisture penetration and a reduction in the thermal insulation properties be the insulating layer. The constructions connected by bars are punctual The transport of room moisture to the outside via the individual bridge is possible, quantitatively Experience has shown that the cross-sections of a few bars are not sufficient for a newly upholstered Allowing construction projects to dry out from the inside out and, in addition, the living-related Discharge moisture to the outside.
In jüngster Zeit sind Versuche bekannt geworden, nach denen spezielle Mauerziegel, die für Wandelemente nach DIN 4159 geeignet sind, in den vergrößerten äußeren Lochreihen im 2-Komponentenverfahren mit Polyurethanschaum ausgefüllt werden. Diese Konstruktion hat einen entscheidenden Vorteil gegenüber den bisherigen Möglichkeiten: Die Außenschale dieses Mauerziegels ist über mehrere senkrecht durchlaufende Stege mit dem tragenden Querschnitt verbunden. Recently, attempts have become known, according to which special Bricks, which are suitable for wall elements according to DIN 4159, in the enlarged outer rows of holes are filled with polyurethane foam in a 2-component process. This construction has a decisive advantage over the previous options: The outer shell of this brick is over several vertical webs connected to the load-bearing cross-section.
So kann die Raum feuchte ausreichend, quasi an der Isolierung vorbei, nach außen abgeleitet werden. Nachteilig bei diesem Verfahren ist die nicht einfache Herstelltechnik der Schaumisolierung und der hohe Preis des zu verwendenden Rohstoffmaterials.In this way, the room can be sufficiently humid, almost bypassing the insulation, to be diverted to the outside. The disadvantage of this method is that it is not simple Manufacturing technology of foam insulation and the high price of the raw material to be used.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen speziell gelochten Baustein - insbesondere Hochlochziegel mit geeigneten Lechquerschnitten mit preisgünstigen Thermoplastkunststoffen - vom Granulat ausgehend - auszuschäumen.The present invention has for its object to be a special Perforated building block - especially vertically perforated brick with suitable hole cross-sections With inexpensive thermoplastics - starting from the granulate - foaming.
Das erfindungsgewä.ße Verfahren sieht vor, einzelne Lochquerschnitte oder ganze Reihen von Hohlräumen teilweise oder völlig mit vorgeschä ten Granulaten mecahnisch durch Einblassen, Aufschütten, Einrütteln odsAr dgl. auszufüllen. Im anschließenden Arbeitsgang werden die Granulate durch Zuführung von Wärmer gie e expandiert, wobei gleichzeitig eine restlose Verfüllung der Hohlräume entsteht und die Granulate miteinander sowie mit den Wandungen der Hohlräume feste Verbindungen eingehen. Der Dampfdruckausgleich erfolgt über die Stege und/oder den dampfdurchlässig verschäumten Wärmelömmstoff. The method according to the invention provides for individual hole cross-sections or whole rows of cavities partially or completely with vorä th granules To be filled in mechanically by blowing in, pouring in, shaking in or the like. in the subsequent operation, the granules are gie e by adding heat expands, whereby at the same time a complete filling of the cavities occurs and the granules with each other and with the walls of the cavities fixed connections enter. The vapor pressure equalization takes place via the webs and / or the vapor-permeable foamed thermal insulation material.
Dic mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Herstellung vollautomatisch mit einem preisgünstigen Wärmedüsenstoff erfolg n kann und durch die Dampfoffenheit der erfindungsgemäßen Mauersteine die Gafahr der Kondenswasserbildung vermieden wird. The advantages achieved with the invention are in particular that the production is fully automatic with an inexpensive heat nozzle material n can and due to the steam openness of the bricks according to the invention, the risk the formation of condensation is avoided.
