Description

Gitter für Fußböden aus Tragschienen und Querstäben Die Erfindung betrifft Gitter für Fußböden aus Tragschienen und Querstäben eckigen Querschnittes, welch letztere im oberen Rande der Tragschiene befestigt sind und mit ihren Oberkanten über die Ebene der Tragschienen hervorragen.Grids for floors made of support rails and cross bars The invention relates to grids for floors made of support rails and cross bars of angular cross-section, which latter are attached in the upper edge of the mounting rail and with their upper edges protrude above the level of the mounting rails.

Bei den bekannten Gittern dieser Art bestehen die Querstäbe aus geraden glatten Stäben, die ein Ausgleiten in der Richtung ihrer Oberkanten zulassen.In the known grids of this type, the cross bars consist of straight bars smooth rods that allow sliding in the direction of their upper edges.

Gemäß der Erfindung sind nun zur Herstellung einer rauhen Oberfläche der Gitter die Querstäbe um ihre Achsen verwunden. Hierdurch wird insbesondere eine nach jeder Richtung hin wirksame Sicherheit gegen Ausgleiten geschaffen.According to the invention are now to produce a rough surface the lattice twist the cross bars about their axes. This is in particular a Effective security against slipping created in every direction.

Die Zeichnung stellt beispielsweise eine Ausführungsform des Erfindungsgegenstandes dar, und zwar zeigt die Abb. i eine Aufsicht, die Abb. 2 einen Längsschnitt und die Abb. 3 einen Querschnitt des Gitters. . Eine Anzahl von Tragschienen i aus Metall von beliebiger Normalgröße liegen mit Zwischenräumen gleichlaufend zueinander. Mit den Tragschienen sind um ihre Achsen verwundene Querstäbe 2 verbunden.The drawing represents, for example, an embodiment of the subject matter of the invention represents, namely the Fig. i shows a plan view, Fig. 2 shows a longitudinal section and Fig. 3 shows a cross section of the grid. . A number of support rails i made of metal of any normal size lie parallel to one another with spaces in between. With Cross bars 2 twisted about their axes are connected to the support rails.

Die durch das Verwinden entstehenden Kanten der Stäbe 2 ragen etwas über die Ebene der oberen Kanten der Tragschienen i hervor, so daß eine scharfe Fläche entsteht, von der man nicht abgleiten kann. Die Öffnungen zwischen den Schienen und Stäben ergeben Luftöffnungen für das Gitter.The edges of the rods 2 resulting from the twisting protrude somewhat above the plane of the upper edges of the mounting rails i, so that a sharp Surface is created from which one cannot slide. The openings between the rails and bars provide air openings for the grille.

Die Querstäbe 2 sind an den oberen Rändern der Schienen i durchAnschweißen angeschlossen, und zwar zweckmäßig durch elektrische Schweißung. Das Gitter ist außerordentlich fest und ferner auch billig herzustellen, da für die Tragschienen und die verwundenen Querstäbe Normalstäbe verwendet werden und außerdem die Anwendung der verwundenen Stäbe eine durchgängige und schnelle Verbindung der Schienen und Stäbe gestattet. Die verwundenen Querstäbe ergeben insbesondere eine große Anzahl von Berührungspunkten mit den Rändern der Schienen i und bewirken hierdurch eine bessere Erhitzung der Schienen als runde oder kantige Stäbe mit glatter Oberfläche.The cross bars 2 are welded to the upper edges of the rails i connected, expediently by electrical welding. The grid is extremely strong and also cheap to manufacture, as for the mounting rails and the twisted cross bars normal bars are used and also the application the twisted bars a continuous and fast connection of the rails and Rods allowed. The twisted cross bars in particular result in a large number of points of contact with the edges of the rails i and thereby cause a better heating of the rails than round or angular rods with a smooth surface.
