Description
Deckenhohlkörper. Bei den Hohlkörpexdecken werden heute fast ausschliesslich Ziegel- und Schlacken- hohlkörper verwendet. Sie besitzen aber den Nachteil, dass sie schwer sind-, abgesehen davon, dass sie häufig salpeterhaltig sind.
Es liegt somit nahe, einen Hohlkörper zu finden, der leichter und billiger ist, und sonst Vorteile besitzt, die dien Hohlziegel nicht eigen sind. Die Zeichnung veran schaulicht im Längsschnitt, im Querschnitt und in perspektivischer, die Verwendungs weise zeigender Darstellung ein Ausfüh rungsbeispiel des Erfindungsgegenstandes.
Der gezeichnete Hohlkörper unterscheidet sich vom Hohlziegel dadurch, dass er erstens aus einem Holzgerippe und einem Überzug aus Textilstoff, z. B. aus Jute, besteht, in .der Längenabmessung unbegrenzt und vor allem leicht und nagelbar ist. Wie aus den Detailzeichnungen ersichtlich ist, besteht das Gerippe aus einer Anzahl Querbrettchen a, ,die in kurzen Abständen mit Leisten b ver nagelt sind, um welche der Überzug fest aufgespannt ist.
Die obern vier Leisten sind so stark bemessen, dass man bequem Beton darüber fahren kann, falls solche Decken- hohlkörper eine Betonschicht h zu tragen be stimmt sind. Das Gerippe an sich ist ver steift. Die Querbrettchen a ermöglichen das Einschlagen von Nägeln -c, welche Rippen eisen in gewünschten Horizontalabständen halten, zugleich aber auch den Hohlkörper in die Trägerrippen befestigen. Die Nasen d an den Querbrettchen ermöglichen ebenfalls, dass die Armierungseisen schön in den Be ton eingebettet werden, Vorteile, wie man sie bei keinem Ziegel- oder Schlackenhohl körper findet.
Es ist somit eine tadellose Eisenlage gewährleistet, was für die Güte der Deckenkonstruktion sehr wichtig ist. Dem Hohlkörper fallen folgende Vorteile zu: Nach dem Ausschalen, d. h. Entfernen cler Bretter und Balken g wird durch den Überzug aus Textilstoff eine glatte Schicht gebildet, die gestrichen oder tapeziert wer den kann, was für teanporäre Bauten, La gerräume etc. genügen dürfte.
Jedoch kann jeder beliebige Plafond aufgenagelt oder geleimt werden, was nachher eine schall sichere und warme Hohlkörperdecke gibt.
Wenn der Überzug appretiert ist, lässt sie das Betonwasser erst nicht durch. Sollte die Jute aber doch durchnässt werden, so wird das Wasser aber nicht entzogen, wie es bei Ziegeln der Fall ist:, sondern nur auf gespeichert, um später vom Beton selber wie der abgesogen zu werden. Wenn bei über mässig nassem Beton die Jute Wasser durch lassen würde, so wäre das belanglos, weil dann nur überschüssiges Wasser abzieht, der Zement aber zurückgehalten wird, in folge der filtrierenden Eigenschaft der Jute. Besonderen Vorteil bietet der Überzug beim Betonieren im Winter, indem sie an sich warm ist und den Beton quasi isoliert vor der Kälte.
Weil die Hohlkörper in Normallängen von 2 cm und mehr hergestellt werden kön nen, und in der Breitenabmessung 50 cm betragen können, so kann in kurzer Zeit eine grosse Fläche verlegt werden, was durch das geringe Gewicht der Körper noch be günstigt wird. Durch das geringe Eigen gewicht vermindert sich die Armierung der Decke ganz gewaltig. Die Montageschalung reduziert sich zum Beispiel auf 0,5 m2 pro Quadratmeter-Decke.
Ceiling hollow body. Hollow brick and slag ceilings are almost exclusively used today in hollow body ceilings. However, they have the disadvantage that they are heavy, apart from the fact that they often contain nitre.
It is therefore obvious to find a hollow body that is lighter and cheaper, and otherwise has advantages that are not inherent in the hollow bricks. The drawing illustrates an exemplary embodiment of the subject matter of the invention in longitudinal section, in cross section and in perspective, the use-wise showing representation.
The drawn hollow body differs from the hollow brick in that it firstly consists of a wooden frame and a cover made of textile material, e.g. B. made of jute, is unlimited in the length dimension and, above all, is easy and nailable. As can be seen from the detailed drawings, the framework consists of a number of transverse boards a, which are nailed ver at short intervals with strips b, around which the cover is firmly stretched.
The four upper strips are dimensioned so thick that concrete can be comfortably driven over them if such hollow ceiling bodies are intended to support a concrete layer h. The skeleton itself is stiffened. The cross boards a allow the hammering of nails -c, which keep iron ribs at the desired horizontal distances, but at the same time also fasten the hollow body in the support ribs. The noses d on the transverse boards also enable the reinforcing bars to be embedded nicely in the concrete, advantages that are not found in any brick or cinder block.
This guarantees a flawless iron layer, which is very important for the quality of the ceiling construction. The hollow body has the following advantages: After stripping, d. H. Removing the boards and beams g creates a smooth layer through the cover of textile material, which can be painted or papered, which should be sufficient for temporary buildings, storage rooms, etc.
However, any ceiling can be nailed or glued on, which then gives a sound-safe and warm hollow-core ceiling.
Once the coating is finished, it does not let the concrete water through. However, if the jute gets soaked, the water is not withdrawn, as is the case with bricks, but only stored in order to later be sucked off by the concrete itself. If the jute were to let water through in the case of excessively wet concrete, this would be irrelevant, because then only excess water is drawn off, but the cement is retained due to the filtering properties of the jute. The coating offers a particular advantage when concreting in winter because it is warm in itself and the concrete virtually insulates it from the cold.
Because the hollow body can be produced in normal lengths of 2 cm and more, and the width dimension can be 50 cm, a large area can be laid in a short time, which is still favored by the low weight of the body. Due to the low weight, the reinforcement of the ceiling is greatly reduced. The assembly formwork is reduced, for example, to 0.5 m2 per square meter ceiling.
