    Schalungsgerüst zur Herstellung einer Eisenbeton-Zellendecke.   



   Die vorliegende Erfindung betrifft ein Schalungsgerüst zur Herstellung einer   Eiaenbeton-   Zellendecke. 



   In der Zeichnung zeigen Fig. 1 einen Querschnitt durch die eingeschalte Decke, Fig. 2 einen Schnitt nach   A-B   in Fig. 1, Fig. 3 einen Querschnitt durch die fertige Decke, in ausgeschaltem Zustande mit fertiggestelltem unterseitigen Plafond. 



   Auf entsprechend unterstützten Unterzughölzern a werden hochkantig gestellte Halbpfosten (Bretter, Riegel, Staffelhölzer) b von der annähernden Stärke der herzustellenden Betonstege h in den Abständen der Zellenbreite verlegt und befestigt. Dann werden iiber die Oberkante   dieser Holzer b   schmale Streifen c von Rohrgewebe (Rabitzgitter, Eisendraht oder Trespengewebe) gelegt ; welche den späteren Plafondputz tragen sollen und welche in den Betonstegen der Decke   ihre natürliche   Befestigung finden, indem sie durch den erhärtenden Zementbeton umschlossen und festgehalten werden. Weiters werden in die Hölzer b seitlich Holzschrauben (oder Wirbel) eingeschraubt, oder Bankhaken (Stifte, Drähte, Dübel u. dergl.)   d   eingeschlagen oder Leisten angenagelt, auf welchen die Zellenschalungshauben e ihr Auflager finden.

   Letztere werden aus Holzbrettern oder Blech in jener Form hergestellt, welche die zellenförmigen Hohlräume f zwischen den Betonstegen h der Decke bekommen sollen und werden stumpf aneinander angestossen oder mit ihren Enden übereinander gelegt, um eine betondichte Schalung zu erreichen. Der Abschluss einer Zelle gegen das Mauerauflager oder gegen einen Träger etc. erfolgt durch ein eingesetztes

 sind dann zwischen den Hölzern b und den Zellenschalungshauben e eingeklemmt. 



   Nachdem so die herzustellende Decke eingeschalt ist, wird vorerst je eine kleine Menge weichen, fetten Betons in die Zwischenräume zwischen die Blechhauben e eingefüllt, welcher   Betonmörtel   zwischen die Maschen des Rohr-oder Drahtgewebes c eindringt und dessen spiitere Befestigung besorgt. Dann werden in bekannter Weise die Eisenstäbe g der Betonstege h eingebettet und diese Betonstege h samt deren oberer Gurtplatte   1. : voll   ausbetoniert.

    Formwork scaffolding for the production of a reinforced concrete cell ceiling.



   The present invention relates to a formwork framework for the production of an egg concrete cell ceiling.



   In the drawing: Fig. 1 shows a cross section through the covered ceiling, Fig. 2 shows a section according to A-B in Fig. 1, Fig. 3 shows a cross section through the finished ceiling, in the closed state with the finished ceiling below.



   Half-posts (boards, bars, wooden staves) b of the approximate thickness of the concrete webs h to be produced are laid and fastened on appropriately supported supporting timber a at the intervals of the cell width. Narrow strips c of tubular fabric (rabitz lattice, iron wire or bristle fabric) are then placed over the upper edge of these Holzer b; which will later carry the plaster of the ceiling and which will find their natural fixation in the concrete webs of the ceiling by being enclosed and held in place by the hardening cement concrete. Furthermore, wood screws (or swivels) are screwed into the wood b at the side, or bench hooks (pins, wires, dowels, etc.) d hammered in or bars nailed on, on which the cell formwork hoods e find their support.

   The latter are made of wooden boards or sheet metal in the shape that the cellular cavities f between the concrete webs h of the ceiling should get and are butted against each other or placed with their ends on top of each other in order to achieve a concrete-tight formwork. The closure of a cell against the wall support or against a carrier etc. is carried out by an inserted
 EMI1.1
 are then wedged between the timbers b and the cell shuttering hoods e.



   After the ceiling to be produced has been shuttered in this way, a small amount of soft, greasy concrete is first poured into the spaces between the sheet metal hoods e, which concrete mortar penetrates between the meshes of the pipe or wire mesh c and its subsequent attachment. Then the iron rods g of the concrete webs h are embedded in a known manner and these concrete webs h together with their upper belt plate 1.: fully concreted.



   While with other similar iron ceilings, the entire formwork has to remain under the concrete ceiling until it has fully hardened, which results in a period of 3-6 weeks. speaks, know the complicated with the present cell ceiling. More expensive parts of the formwork are the elastic sheet metal or wooden hoods e of the cells) can be removed after 1 to 2 days (after removing or twisting the support screws d), while only the rough wooden supports Cl and b of the ceiling are left to their full hardening stop. 80 that the cost of the formwork as a result of its rapid reusability is significantly lower than with all previously known, conventional methods.



   As soon as the formwork is removed. the strips c of tubular fabric hanging down on both sides of each concrete web h. Iron mesh and the like .. which are held in the concrete rods both by the concrete itself and by hanging iron that may be embedded in concrete. Drawn between two rods across the cell cavity and linked and connected by means of their iron wires, creating a tightly stretched ceiling fabric made of pipe, iron wire, etc. under the reinforced concrete cell ceiling.
