Description

Hochziehbare Schalung Die Erfindung betrifft eine zwischen Pfosten hochziehbare Schalung.Pull-up formwork The invention relates to an intermediate post pull-up formwork.

Erfindungsgemäß bestehen die Schalungsplatten oder Schalungstafeln aus mehreren lose durch Ketten-, Haken- oder ähnliche Glieder miteinander verbundenen, nacheinander hochziehbaren Brettern öder Leisten.According to the invention, there are formwork panels or formwork panels from several loosely connected by chains, hooks or similar links, boards or strips that can be pulled up one after the other.

Der Fortschritt bei Verwendung derartiger zwischen Pfosten gleitender Schalungsplatten liegt einmal darin, daß beim Hochziehen der einzelnen Bretter oder Leisten nacheinander eine verminderte Reibung infolge geringerer Flächenanlage an dem Beton zu überwinden ist und durch Heben und Senken der einzelnen Bretter eine Glättung der Betonfläche erfolgen kann. Des weiteren darin, daß durch Auseinanderziehen der Bretter innerhalb der Schalungstafeln Luftschlitze entstehen, wodurch ein erhöhter seitlicher Luftzutritt zu den Betonflächen und somit eine Beschleunigung des Abbindens und Erhärtens _ der Masse erreichbar ist.The progress in using such inter-post sliding Formwork panels is once that when pulling up the individual boards or One after the other, they offer reduced friction as a result of less surface contact the concrete is to be overcome and by raising and lowering the individual boards a Smoothing the concrete surface can be done. Furthermore in that by pulling them apart of the boards within the formwork panels, air slots are created, which increases the lateral air access to the concrete surfaces and thus an acceleration of the setting and hardening _ of the mass is achievable.

In den Zeichnungen ist die Erfindung in einem Ausführungsbeispiel dargestellt und zeigen Abb. i und z die Schalung mit geschlossenen (zusammengeschobenen) Brettern oder Leisten im Schnitt und Ansicht, Abb. 3 und 4 dieselbe Schalung mit geöffneten (auseinandergezogenen) Brettern öder Leisten im Querschnitt und Ansicht.In the drawings the invention is in one embodiment and show fig. i and z the formwork with closed (pushed together) Boards or strips in section and view, Fig. 3 and 4 with the same formwork open (pulled apart) boards or strips in cross-section and view.

In angemessenen Abständen stehen längs der herzustellenden Betonmauern beiderseitig, und zwar je zwei gegenüber, Pfosten P, in deren Nuten Schalungsplatten auf- und abwärts gleiten können. Letztere sind zusammengesetzt aus einzelnen Brettern oder Leisten b, die miteinander durch lösbare Ketten oder Haken c verbunden sind, so daß die Bretter sowohl zusammen als auch nacheinander in beliebigen Abständen hochgezogen werden können.Stand at appropriate intervals along the concrete walls to be produced on both sides, two opposite each other, posts P, in their grooves formwork panels slide up and down. The latter are composed of individual boards or strips b, which are connected to each other by detachable chains or hooks c, so that the boards both together and one after the other at any distance can be pulled up.

Der Arbeitsvorgang ist folgender: Das Füllgut wird lagenweise eingestampft etwa bis zur Höhe h (Abb. i). Alsdann werden die Schalbretter etwas angezogen, so daß zwischen ihnen seitliche Luftschlitze i entstehen (Abb.3 und q.). Durch diese Luftschlitze i findet eine Luftumspülung der Betonmasse statt, dadurch aber eine erhebliche Beschleunigung des Abbindeprozesses.The process is as follows: The filling material is pulped in layers up to about height h (Fig. i). Then the shuttering boards are tightened a little, like this that between them lateral air slots i arise (Fig.3 and q.). Through this Air slits i, the concrete mass is flushed with air, but thereby one considerable acceleration of the setting process.

Sobald die erste Schicht u-n etwas Auflast vertragen kann, werden die Platten aufgezogen und über der Schüttungsoberfläche h neu angesetzt, und der Vorgang wiederholt sich nach oben hin.As soon as the first layer can take a bit of load the plates pulled up and reattached over the bed surface h, and the The process is repeated upwards.

Fenster-, Tür- und Maueröffnungen werden vermittels Rahmen oder Lehren zwischen den Schalungsplatten eingesetzt und mit Beton umfüllt. Die Bretter gleiten an ihnen vorbei. -Eine derartige hochziehbare Schalung erleichtert alle seither in Übung befindlichen Betonausführungen und -mischungen dadurch, daß jederzeit durch die Schlitze eine Beobachtung der Flächen und Massen erfolgen kann.Window, door and wall openings are made by means of frames or gauges inserted between the formwork panels and filled with concrete. The boards slide past them. -A pull-up formwork of this kind has made everyone easier since then Concrete executions and mixes in practice by being carried out at any time The slots allow observation of the areas and masses.
