Description

Die Erfindung bezieht sich auf eine Kaminschalung.The invention relates to chimney formwork.

Gegenwärtig werden die Kamine für Gebäudeheizungen oder dgl. meist aus vorgefertigten Formsteinen erstellt, wie dies z.B. aus der DE-A-1 027 869 bekannt ist. Die Formsteine enthalten das Kaminrohr bzw. Futter, die in einer verputzbaren Masse eingeschlossen sind. Zwar sind die bekannten Formsteine schnell zu einem fertigen Kamin zusammengesetzt, ihr Transport ist jedoch wegen des höheren Gewichtes aufwendig und teuer.Currently, the chimneys for building heating or the like. mostly created from prefabricated shaped stones, such as this is known from DE-A-1 027 869. The shaped stones included the chimney pipe or lining, in a plasterable mass are included. Although the well-known shaped stones quickly assembled into a finished fireplace, their transportation is complex and because of the higher weight expensive.

Die DE-A-43 14 285 beschreibt einen Fertigkamin, der vollständig im Fertigungsbetrieb vorgefertigt und danach auf die Baustelle transportiert wird. Die Herstellung des Kamins erfolgt in den üblichen, wiederverwendbaren Schalungen. Auch hier ergibt sich das Problem des sicheren Transports auf die Baustelle.DE-A-43 14 285 describes a prefabricated fireplace that is complete prefabricated in the manufacturing plant and then on the Construction site is transported.

Das erfindungsgemäße Schalungselement erlaubt die Herstellung des Kamins in situ, d.h. das Schalungselement wird im Verlauf des Schalungsaufbaus beispielsweise für Wände oder Decken aufgebaut und anschließend beim Vergießen der Wände bzw. Decken mit verfüllt, so daß ein sehr zügiger, und nicht durch andere Arbeiten unterbrochener Arbeitsablauf auf der Baustelle möglich ist. Das erfindungsgemäße Schalungselement ist als verlorene Schalung ausgebildet und verbleibt im fertigen Beton, wobei durch die Verwendung von Putzträgermaterial als Schalungswand auch das anschließende Verputzen erleichtert wird.In the chimney formwork according to the invention, only the prefabricated ones have to be made Formwork elements are transported, which is a relative lightweight plaster base material as the outer shell and that also light, mostly made of stainless steel chimney pipe include. The formwork element according to the invention allows the production of the fireplace in situ, i.e. the formwork element is used in the course of formwork construction, for example for walls or ceilings and then when casting the Walls or ceilings filled with, so that a very quick, and workflow not interrupted by other work the construction site is possible. The formwork element according to the invention is designed as lost formwork and remains in the finished concrete, taking through the use of plaster base material the subsequent plastering also facilitates as formwork wall becomes.

Gemäß Anspruch 2 kann auch die gegebenenfalls notwendige Isolierung in das Schalungselement mit eingebaut werden.According to claim 2, the possibly necessary insulation can be built into the formwork element.

Das in Anspruch 3 beschriebene Material für die Schalungswand ist genügend ausgesteift, um dem Betonierdruck widerstehen zu können. Durch die Fertigung aus Metall kann die Schalungswand in den unterschiedlichsten Querschnittsformen je nach Einsatzzweck erstellt weden, was insbesondere bei der Rekonstruktion oder Nachrüstung in vorhandenen Gebäuden von Vorteil ist.The material for the formwork wall described in claim 3 is braced enough to withstand the concrete pressure can. The formwork wall can be made of metal in various cross-sectional shapes depending on the application Weden created, especially in the reconstruction or retrofitting in existing buildings is an advantage is.

Anspruch 4 beschreibt ein besonders bevorzugtes Material für die Schalungswand.Claim 4 describes a particularly preferred material for the formwork wall.

Besonders hohe Einsparungen an Einbauzeit für die Schalung bzw. Fertigungszeit für den Kamin ergeben sich mit geschoßhoch vorgefertigten Kaminschalungen gemäß Anspruch 5.Particularly high savings in installation time for the formwork or the manufacturing time for the chimney is as high as a storey Prefabricated chimney formwork according to claim 5.

Die Fig. 1 und 2 zeigen in Drauf- und Vorderansicht ein Schalungselement 1 für eine erfindungsgemäße Kaminschalung. Das Schalungselement 1 ist in Geschoßhöhe vorgefertigt, wobei für mehrgeschossige Gebäude die gesamte Kaminschalung aus zwei oder noch mehr einzelner Schalungselemente 1 zusammengesetzt werden kann.1 and 2 show a formwork element in plan and front view 1 for chimney formwork according to the invention. The Formwork element 1 is prefabricated at floor level, whereby for multi-storey building the entire chimney formwork from two or assembled even more individual formwork elements 1 can be.

Jedes Schalungselement 1 hat eine Schalungswand 2, die aus einem Putzträgermaterial besteht, das zu einem an gegenüberliegenden Seiten offenen Hohlkörper mit einem vorbestimmten Querschnitt geformt wurde. Die Schalungswand 2 besteht aus einem zwischen die Querstäbe 3 und die Längsstäbe 4 eines metallischen Gitterwerks eingeschlossenen Streckmetalltafel 5. Dieses Material ist beispielsweise in der EP-A-507 054 beschrieben, auf die hiermit Bezug genommen werden soll. Die Quer- und Längsstäbe 3, 4 bestehen aus Baustahl und versteifen die Streckmetalltafel 5, so daß sich ein selbsttragendes Schalungselement 1 ergibt.Each formwork element 1 has a formwork wall 2 that a plaster base material, which to one on opposite Sides open hollow body with a predetermined Cross-section was formed. The formwork wall 2 consists of one between the cross bars 3 and the longitudinal bars 4 of a metallic Expanded metal sheet 5 enclosed in the latticework. This material is described, for example, in EP-A-507 054, to which reference is hereby made. The Cross and longitudinal bars 3, 4 are made of structural steel and stiffen the expanded metal plate 5, so that a self-supporting Formwork element 1 results.

Zentriert innerhalb des von der Schalungswand 2 umschlossenen Querschnittes ist ein übliches Kaminrohr 6 beispielsweise aus Edelstahl angeordnet und durch Querstreben 7 im vorbestimmten Abstand zur Schalungswand 2 gehalten.
