Description
Den Gegenstand, der Erfindung bildet eine abgeänderte Ausführungsweise des Verfahrens zur Herstellung von Eisenbetonplattenhalkendecken nach Patent 805 552. Nach diesem Patent dienen zur Herstellung der Decke paarweise aneinanderstoßend verlegte Eisenbetonträger mitI-Profil, deren nach außen ragende Flanschen dazu verwendet werden, um mittels Keile Riegel zu befestigen, die eine zuerst als Schalung für den Guß der Druckplatte dienende Bretterlage tragen, welche dann nach Abbinden der Druckplatte in umgekehrter Anordnung zur Bildung einer ebenen Untersicht dient.The object of the invention is a modified embodiment of the method for the production of reinforced concrete slab ceilings according to patent 805 552. According to this patent, reinforced concrete beams with an I-profile, laid in pairs butting against one another, are used to produce the ceiling, the outwardly protruding flanges of which are used to lock bolts by means of wedges fasten, which carry a first serving as formwork for the casting of the pressure plate layer of boards, which is then used after setting of the pressure plate in the reverse arrangement to form a flat soffit.
Erfindungsgemäß kann das gleiche Verfahren, wenn die an die Decke gestellten Festigkeitsanforderungen wesentlich geringer sind, auch angewendet werden, wenn statt paarweise aneinanderstoßend verlegter Eisenbeton-I-Träger nur einzeln liegende Eisenbeton-I-Träger mit beiderseits symmetrisch angeordneten, an der Innenseite schräg abfallenden Flanschenflächen vorgesehen sind.According to the invention, the same method can be used if the ceiling strength requirements are significantly lower, can also be used, if reinforced concrete I-girders are laid individually instead of butting in pairs Lying reinforced concrete I-beams with symmetrically arranged on both sides, on the inside sloping flange surfaces are provided.
In der Zeichnung ist als Ausführungsbeispiel der Erfindung eine Eisenbetonplattenbalkendecke in vertikalem Schnitt quer zur Balkenlängsrichtung dargestellt, wobei die linke Hälfte der Zeichnung den Zustand beim Guß der Plattenbalkendecke und die rechte Hälfte die fertige Decke darstellt.In the drawing, a reinforced concrete slab beam ceiling is an embodiment of the invention shown in vertical section transverse to the longitudinal direction of the bar, the left Half of the drawing shows the state during the casting of the plate beam ceiling and the right Half represents the finished ceiling.
Die Rippen oder Balken der Decke sind durch Eisenbetonträger mit I-Profil 21 gebildet, die ein gemäß den statischen Anforderungen dimensioniertes Zugeisen 22 und ein Montageeisen 23 enthalten. Zur Aufnahme der Schubspannungen dienen die Bügel 24.The ribs or beams of the ceiling are made of reinforced concrete beams with an I-profile 21 formed, which is dimensioned according to the static requirements 22 and an assembly iron 23 included. To absorb the shear stresses are used Bracket 24.
Die Träger besitzen beiderseits symmetrisch ausragende, kräftig dimensionierte Flansche 25 mit schräg abfallenden inneren Begrenzungsflächen 26. An der Oberseite ragen Bügel 27 heraus, die zur Aufnahme der zwischen Druckplatte 28 und Träger auftretenden Schubspannungen und zur untrennbaren Verbindung zwischen Druckplatte und Träger dienen.The girders have strong dimensions that protrude symmetrically on both sides Flanges 25 with sloping inner boundary surfaces 26. At the top protrude bracket 27, which is used to accommodate the occurring between the pressure plate 28 and carrier Shear stresses and the inseparable connection between the pressure plate and the carrier to serve.
Zur Herstellung der Druckplatte und ebenen Untersicht geht man nun, ganz analog, wie im Hauptpatent beschrieben, wie folgt vor: Zum Guß der Druckplatte 28 wird eine Schalung aus Brettern 30 verwendet, die, wie in der Zeichnung links dargestellt, parallel zur Längsrichtung der Träger 21 angeordnet werden und auf Querriegeln 31 aufruhen, die wieder mittels Keile 32 befestigt sind. Die Form der Riegel 31 und Keile 32 ist so gewählt, daß sie bei mäßigem Anziehen an den Schrägflächen 26 der Flansche 25 durch Reibung sicher festsitzen.To make the printing plate and the level soffit, go now, quite analogously, as described in the main patent, as follows: To cast the printing plate 28 a formwork made of boards 30 is used, which, as in the drawing on the left shown, are arranged parallel to the longitudinal direction of the carrier 21 and on Rest cross bars 31, which are fastened again by means of wedges 32. The shape of the Latch 31 and wedges 32 is chosen so that they are with moderate tightening on the inclined surfaces 26 of the flanges 25 fit securely by friction.
Nach vollendetem Guß und Abbinden der Druckplatte 28 wird die Schalung 30, 31, 32 abgenommen und so, wie die Zeichnung auf der rechten Hälfte zeigt, umgekehrt wieder an den Trägern montiert. Auf diese Weise werden die einmal zugeschnittenen Bretter und Riegel, ohne daß irgendein Holzverlust eintritt, dazu verwendet. um eine ebene Untersicht zu erhalten, auf welcher dann Rohrgewebe, Heraklithplatten 33 od. dgl. als eigentliche Träger des Deckenverputzes 34 über die Balken hinweg befestigt werden, wodurch keine Risse an den Fugen auftreten können.After the casting has been completed and the pressure plate 28 has set, the formwork 30, 31, 32 removed and so, as the drawing on the right half shows, reversed reassembled on the girders. This way the once cropped Boards and bars are used for this without any loss of wood. around to obtain a level soffit, on which tubular fabric, Heraklith plates 33 or the like as the actual carrier of the ceiling plaster 34 over the beams fastened, which means that cracks cannot appear in the joints.
Die I-Träger lassen sich leicht auf gedecktem Arbeitsplatz oder in geschlossenen Räumen gießen. Außer einer Montagestütze ist beim Verlegen der Balken keine weitere Schalung erforderlich. Diese Deckenbauart eignet sich vor allem für den Wohnungsbau, wobei die Feldweite im Durchschnitt etwa 0,75 m beträgt.The I-beams can easily be poured on a covered workplace or in closed rooms. Apart from an assembly support, no further formwork is required when laying the beams. This type of ceiling construction is particularly suitable for residential construction, with the field width averaging around 0.75 m.
