Description

Bei den bisher bekannten Rollgittern wird zur Herstellung ausschließlich Rundeisen und Bandeisen verwendet. Bei Druck von vorn gegen ein abgerolltes Gitter aus diesem Material biegen sieh diese Gitter leicht nach hinten durch.In the case of the previously known rolling grilles, only Round iron and band iron used. When pressure is applied from the front against an unrolled grid from this material you can see these grids bend backwards slightly.

Um gegen dieses Durchbiegen eine größere Stabilität zu erzielen, kommt bei der vorliegenden Erfindung ein Quadrateisen zur Verwendung, und zwar so, daß dessen rechtwinklige Flächen der einzelnen Stäbe schräg im halben rechten Winkel zur abgerollten Gitterfläche stehen, wie aus der Abbildung,ersichtlich.In order to achieve greater stability against this bending, comes in the present invention a square iron for use in such a way that whose right-angled surfaces of the individual rods are inclined at half a right angle stand facing the unrolled grille surface, as shown in the illustration.

Das Widerstandsmoment des Quadrateisens in der beschriebenen Kantenstellung bei waagerechtem Druck ist größer als bei Rundeisen von gleichem Querschnitt.The section modulus of the square iron in the described edge position with horizontal pressure is larger than with round bars of the same cross-section.

Durch diese Kantenstellung des Quadrateisens, auf die ganze Fläche eines abgerollten Gitters wirkend, wird eine größere Stabilität gegen Durchbiegen erreicht.Through this edge position of the square iron, on the entire surface Acting as a rolled-up grille, there is greater stability against sagging achieved.
