Description

Die Erfindung reiht sich in die Entwicklung moderner Bauweisen ein, die unter Ausschluß von Stahl und Holz die fast alleinige Verwendung von Kunststeinen, Beton, Zement od. dgl. zur Herstellung genormter Fertigkörper und deren Verbindungen im Auge haben. Bei Dächern sind es im besonderen die Firstverbindungen, die Schwierigkeiten machen. Die Erfindung bezieht sich auf die Herstellung eines Betonsparrendaches bzw. Dachstuhles, bei dem die Sparren im First ohne irgendwelche Verbindungseisen, Klammern od. dgl. mit einem Firstbalken aus Beton vereinigt werden. Zu diesem Zweck benutzt man erfindungsgemäß eine leicht aufstellbare und leicht abzubauende Stütz-und Verschalungsvorrichtung, die aus wenigen einfachen Teilen besteht und die im verengten Firstraum nur wenig Platz beansprucht. Die Stütz- und Verschalungsvorrichtung besteht aus Scherenstutzen, in deren oberem Winkel Schalungsplatten liegen, die in regelmäßigen Abständen mit Sohlitzen versehen sind, durch die die oberen Sparrenenden durchtreten. Diese Enden werden in der Verschalung mit dem durchlaufenden Firstbalken aus Stampfbeton oder Gußbeton vereinigt, und die Sparren und der Balken bilden dann einen monolithischen Dachstuhl einfachster Bauform, auf den die Dachhaut aufgelegt wird.The invention is part of the development of modern construction methods, the almost exclusive use of artificial stones, excluding steel and wood, Concrete, cement or the like for the production of standardized prefabricated bodies and their connections have in mind. In the case of roofs, it is especially the ridge connections, the difficulties do. The invention relates to the manufacture of a concrete rafter roof or roof structure in which the rafters in the ridge without any connecting iron, Brackets or the like can be combined with a ridge beam made of concrete. To this end according to the invention, an easily erectable and easy-to-dismantle support is used Formwork device, which consists of a few simple parts and which are narrowed Firestorm takes up little space. The support and formwork device consists made of scissor nozzles, in the upper angle of which are formwork panels, which are in regular Gaps are provided with sole seats through which the upper ends of the rafters pass. These ends are in the formwork with the continuous ridge beam made of stamped concrete or cast concrete combined, and the rafters and the beam then form a monolithic Roof structure of the simplest design on which the roof cladding is placed.

In der Zeichnung ist die Ausführung der Erfindung an einem Beispiel dargestellt.In the drawing, the implementation of the invention is based on an example shown.

Fig. i zeigt die Firstkonstruktion des Beton-Sparrendaches mit der Stütz- und Verschalungsvorrichtung zum Herstellen des mit den Sparrenenden vereinigten Betonfirstbalkens; Fig. 2 zeigt die Ausbildung der auf den Scherenstützen aufgelagerten Schalungsvorrichtung; Fig.3 ist eine Draufsicht auf einen Teil eines fertigen Dachstuhles.Fig. I shows the ridge construction of the concrete rafter roof with the Support and formwork device for the manufacture of the unified with the rafter ends Concrete ridge beam; Fig. 2 shows the design of the superimposed on the scissor supports Shuttering device; Fig. 3 is a plan view of part of a finished roof structure.

ach Fig. i und Fig. 3 besteht der Dachstuhl aus den I3etoiisparren i mit den Enden 2 und den \"erhindern oder dem Boden 3. Die Sparren i sind in üblicher Weise auf den Hauswänden befestigt. Zur Herstellung des Firstes benutzt nian eine lehre, nämlich ein sägebockähnliches Ililfsgerät, (las iin Beispiel aus den Scherenstützen ,1 bestellt und auf dem Dachboden 3 aufgestellt wird. Im olleren Winkel der Scherenarme .4 sind waagerechte. verstellbare Träger 5 (Fil;. 2) angebracht, auf denen rin Balken 6 liegt, Tiber <lein die Versclialungsstützen 7 mit den Winkelstützen 8 aufgesetzt sind. Auf den Winkeln 8 liegen die Verschalungsplatten 9, zwischen denen die Schlitze ioa in regelmäßigen Abständen frei bleiben, in die jeweils die Sparrenenden 2 zu liegen 'kommen. Sind alle Sparren i eingelegt, so wird über den Schalungsplatten 9 und den vorstehenden Sparren-enden 2 der Betonbalken io geformt. Nach Erhärten bilden die Sparrenenden 2 und der Balken.io einen monolithischen Baukörper. Die Spreizung der Scherenarme 4 ist mittels eines mit Rasten od. dgl. versehenen Gestänges einstellbar, so daß die Scherenstützen und die Verschalungsvorrichtung leicht entfernt werden können. Der ganze Firstraum ist nunmehr frei, da behindernde Stützen nicht erforderlich sind. Der Firstbalken io kann auch aus fertigen Teilstücken hergestellt werden, indem die von den Sparrenenden 2 begrenzten Zwischenräume loa getrennt vergossen werden.According to Fig. 1 and Fig. 3, the roof structure consists of the I3etoiis rafters i with the ends 2 and the \ "heighten or the bottom 3. The rafters i are in common Way attached to the house walls. To make the ridge, nian uses a teaching, namely an auxiliary device similar to a sawhorse, (read an example from the scissor supports , 1 is ordered and placed in the attic 3. In the upper corner of the scissor arms .4 are horizontal. adjustable straps 5 (fil ;. 2) attached on which rin beams 6 lies, Tiber <lein the Versclialungsstützen 7 with the angle brackets 8 attached are. On the angles 8 are the formwork panels 9, between which the slots ioa remain free at regular intervals, in each of the rafter ends 2 to lie 'come. If all rafters i are inserted, then the formwork panels 9 and the protruding rafter ends 2 of the concrete beams io formed. After hardening The rafter ends 2 and the beam.io form a monolithic structure. the The scissor arms 4 are spread apart by means of a linkage provided with detents or the like adjustable so that the scissor supports and formwork device are easily removed can be. The entire roof space is now free, as there are no obstructing supports required are. The ridge beam io can also be made from finished pieces are by pouring the gaps loa delimited by the rafter ends 2 separately will.
