Description

Einwandige Kaminsteine, wie sie im Wohnungsbau Verwendung finden, haben zwar den Vorzug, daß sie billig sind, ihre technische Eignung ist jedoch umstritten. Die Wärmespannungen, welche zwischen den Außenflächen und den Innenflächen der einschaligen Wandungen von aus solchen Steinen errichteten Schornsteinen auftreten, sind bei den üblichen Konstruktionen so groß, daß sie von den Wandungen nicht aufgenommen werden können. Diese erhalten Risse, durch welche dann Verbrennungsgase austreten können.Single-walled chimney stones, as they are used in residential construction, Although they have the advantage of being cheap, their technical suitability is controversial. The thermal stresses that exist between the outer surfaces and the inner surfaces of the single-shell Walls of chimneys made of such stones occur are at the usual constructions so large that they are not absorbed by the walls can be. These get cracks through which combustion gases then escape can.

Nach der Erfindung werden die Spannungen in den Wandungen eines aus einwandigen Kaminsteinen hergestellten einschaligen Kamins so weit herabgemindert, daß der Kamin entweder rissefrei bleibt oder daß nur schmale, die Rauchdichtigkeit kaum beeinflussende Haarrisse entstehen.According to the invention, the stresses in the walls are one off single-walled chimney stones made so far down, that the chimney either remains crack-free or that only narrow, the smoke-tightness Barely influencing hairline cracks arise.

Ein Auffangen der Spannungen von der Außenseite der Schornsteine her ist nicht erforderlich, da hier jeweils zwischen der Außenfläche der Wandung und der anschließenden Steinmasse nur Differenzen von beispielsweise 50° C auftreten. Die risseerzeugenden Spannungen entstehen an den Innenseiten der Schornsteinwandungen. Erfindungsgemäß werden sie dort durch Anordnung von gekrümmten oder T-förmigen Dehnungsschlitzen in den einzelnen Kaminsteinen aufgefangen. Die Krümmung der Schlitze bewirkt, daß eine Wärmeübertragung durch Strahlung auf einen Teil des jeweiligen Schlitzes, insbesondere auf dessen Endpunkt, und somit eine unerwünschte- Ausdehnung an diesem Punkt vermieden wird. Die Krümmung des Schlitzes wird zweckmäßig in die Nähe seines Beginns an der Innenseite der Wandung gelegt, weil bei dieser Anordnung die Auswirkung der strahlenden Wärme am geringsten ist.A relief of the tension from the outside of the chimneys is not necessary, as here in each case between the outer surface of the wall and the subsequent stone mass only differences of 50 ° C, for example, occur. The tensions that cause cracks arise on the inside of the chimney walls. According to the invention, they are there by the arrangement of curved or T-shaped expansion slots caught in the individual chimney stones. The curvature of the slots causes a heat transfer by radiation to a part of the respective slot, in particular to its end point, and thus an undesirable expansion at this point is avoided will. The curvature of the slot is conveniently close to its beginning at the Placed inside the wall, because with this arrangement the effect of the radiant Heat is the least.

Der für die Kaminsteine verwendete Baustoff ist beliebig. An sich sind bereits aus einer äußeren Stahlbetonschale und einer inneren Betonschale bestehende Schornsteine bekannt, deren innere Betonschale von innen her in lotrechter Richtung durch strahlige und in waagerechter Richtung durch ringförmige Fugen unterteilt ist.The building material used for the chimney stones is arbitrary. Per se are already made up of an outer reinforced concrete shell and an inner concrete shell Chimneys known whose inner concrete shell from the inside in a vertical direction divided by radial joints and horizontally by ring-shaped joints is.

Gegenüber den bekannten, in der inneren Betonschale von zweischaligen Stahlbetonschornsteinen angeordneten strahligen, ohne Krümmung radial nach außen gerichteten Fugen besteht die Erfindung jedoch in der Anordnung von gekrümmten oder T-förmigen Dehnungsfugen in zur Errichtung von einschaligen Schornsteinen dienenden einwandigen Kaminsteinen.Compared to the well-known, double-shell in the inner concrete shell Reinforced concrete chimneys arranged radial, without curvature radially outwards directed joints, the invention consists in the arrangement of curved or T-shaped expansion joints in the construction of single-shell chimneys single-walled chimney stones.

Die Zeichnung zeigt als Beispiel einen Kaminstein von beliebiger Höhe im Querschnitt. In die Wandung a greifen die gekrümmten Schlitze b bzw. die T-förmigen Schlitze c von innen her ein.The drawing shows an example of a chimney stone of any height in cross section. The curved slots b and the T-shaped slots c engage in the wall a from the inside.
