Description

Verfahren zum Herstellen von vollen oder hohlen Eisen-Beton-Balken Eisen-Beton-Balken, namentlich solche aus Gußbeton, haben die unangenehme Eigenschaft, daß die zur Aufnahme des Putzes dienende Unterschicht infolge Durchsickerns der feinkörnigen Masse bzw. der Betonbrühe spiegelglatt wird, so daß der Putz später sehr schlecht daran haftet.Process for the production of solid or hollow iron-concrete beams Iron-concrete beams, especially those made of cast concrete, have the unpleasant property of that the sub-layer serving to hold the plaster as a result of the seepage of the fine-grained mass or the concrete broth is mirror-smooth, so that the plaster later sticks to it very badly.

Durch das nachstehend beschriebene Verfahren wird diesem Übelstande abgeholfen und die Unterseite von Beton-Balken aller Art, von Stürzen und Abdeckplatten mit einer idealen, körnigen porösen Putzträgerschicht versehen. In die Form oder Schalung wird nämlich zunächst eine ungefähr z bis z12 cm starke Betonschicht a aus beispielsweise 6 Teilen Bims oder einem ähnlichen, körnigen Zuschlagstoff von a bis 5 mm Korngröße und x Teil Zement aufgebracht.The procedure described below avoids this problem and the underside of concrete beams of all kinds, lintels and cover plates provided with an ideal, granular, porous plaster base layer. In the form or Formwork is namely first an approximately z to z12 cm thick concrete layer a from, for example, 6 parts of pumice or a similar, granular aggregate of a up to 5 mm grain size and x part of cement applied.

Da beim Aufbringen von Gußbeton c dieser durch die zuerst eingebrachte körnige Unterschicht a durchsickern und die Porosität vereiteln würde, so wird zunächst auf die körnige Unterschicht p eine mehr plastische, nur mäßig angefeuchtete, etwa 1,`2 cm starke Zwischenschicht b aus beispielsweise 5 Teilen feinkörnigem Sand, Basaltmehl, Steinmehl oder einem ähnlichen feinkörnigen Zuschlagstoff undZement aufgebracht und dann erst der Gußbeton c aufgefüllt. Hierdurch wird ein Durchsickern auch des dünnflüssigsten Gußbetons verhindert, und die untere Schicht der Beton-Balken bleibt so körnig, wie sie eingefüllt wurde.Since when applying cast concrete c this through the first introduced granular sub-layer a would seep through and thwart the porosity, so will initially on the granular lower layer p a more plastic, only moderately moistened, for example 1, `2 cm thick intermediate layer b made of, for example, 5 parts of fine-grain sand, Basalt flour, stone flour or a similar fine-grained aggregate and cement applied and only then filled with the cast concrete c. This will cause a leakage prevents even the thinnest poured concrete, and the lower layer of concrete beams remains as grainy as it was poured in.

PATENTANSPRUCH: Verfahren zum Herstellen von vollen oder hohlen Eisen-Beton-Balken aus dünnflüssigem Gußbeton mit einer körnigen porösen, als Putzträger dienenden Betonschicht, dadurch gekennzeichnet, daß zum Vermeiden des Eindringens des dünnflüssigen Gußbetons in die Putzträgerschicht eine etwa 1/2 cm starke, sehr feinkörnige, plastische und mäßig angefeuchtete Zwischenschicht aus feinkörnigem Sand, Steinmehl oder einem ähnlichen Zuschlagstoff und Zement aufgebracht wird, ehe der dünnflüssige Güßbeton in die Form gegossen wird.PATENT CLAIM: Process for the production of solid or hollow iron-concrete beams made of thin cast concrete with a granular, porous plaster base Concrete layer, characterized in that to avoid the penetration of the low viscosity Cast concrete in the plaster base layer an approximately 1/2 cm thick, very fine-grained, plastic and moderately moistened intermediate layer of fine-grain sand, stone powder or a Similar aggregate and cement is applied before the thin-bodied cast concrete is poured into the mold.
