Abstract
Description
Beschreibung zum Patentgesuch betreffend: "Rinnenabeckrost Die Erfindung bezieht sich auf einen langgestreckten Rinnenabdeckrost mit in Querrichtung verlaufenden schlitzartigen Ablauföffnungen.Description of the patent application pertaining to: "Gutter corner grate The invention refers to an elongated gutter cover grate with transverse ones slot-like drainage openings.
Derartige Roste sind in verschiedenen Ausführungen bekannt. Entweder besitzen sie einen Winkelprofilrahmen, der mit Streckmetall abgedeckt ist, oder sie sind aus einem Blechstreifen hergestellt, dessen Längsränder rechtwinklig oder U-förmig abgekantet sind. Such grates are known in various designs. Either they have an angle profile frame that is covered with expanded metal, or they are made from a sheet metal strip, the longitudinal edges of which are rectangular or Are folded in a U-shape.
Die Erfindung hat sich zur Aufgabe gestellt, bei einfachster Herstellung die Tragfähigkeit der Roste zu erhöhen, um eine nicht unerhebliche Materialersparnis im Verhältnis zum Materialbedarf der bekannten Roste von gleicher Tragfähigkeit zu erzielen. Daneben soll Schmutz- und Rostansätzen an dem Rahmen vorgebeugt werden. The invention has set itself the task, with the simplest production to increase the load-bearing capacity of the grids to save a not inconsiderable amount of material in relation to the material requirements of the known grids of the same load-bearing capacity to achieve. In addition, dirt and rust deposits on the frame should be prevented.
Zur Lösung dieser Aufgabe besteht die Erfindung darin, daß die Längsränder des nach den Maßen des herzustellenden Abdeckrostes zugeschnittenen Blechstreifens zu einem geschlossenen Rund- oder Vierkantprofil eingerollt sind. To solve this problem, the invention consists in that the longitudinal edges of the sheet metal strip cut to the dimensions of the cover grating to be produced are rolled into a closed round or square profile.
Durch das Einrollen der Längsränder zu einem geschlossenen Profil werden neben den äußeren Tragstegen zusätzliche innere Abstützstege für die die langgestreckten Ablauföffnungen aufweisende, plane Rostfläche geschaffen, wodurch die Stützbreite verrinqert wird, so daß für Roste qleicher Tragfähigkeit, wie der herkömmlichen Roste, Bleche dünnes Stärke verwandt werden können, oder mit Blechen gleicher Stärke Roste mit höherer Tragfähigkeit herstellbar sind.By rolling up the longitudinal edges to form a closed profile, additional inner support webs are created for the flat grate surface having the elongated drainage openings in addition to the outer support webs, whereby the support width is reduced, so that the same for grates Load capacity, like the conventional grids, sheets of thin thickness can be used, or grates with a higher load capacity can be produced with sheets of the same thickness.
Dabei behalten die Ablauföffnungen die gleiche Länge und Breite wie bei den bekannten Rosten.The drainage openings keep the same length and width as with the well-known grates.
Auf der Zeichnung soll der Gegenstand der Erfindung beispielsweise veranschaulicht werden. In the drawing, the subject matter of the invention is intended, for example illustrated.
Fig. 1 ist eine Draufsicht auf einen Abdeckrost gemäß der Erfindung, Fig. 2 ist eine Schnittdarstellung entsprechend der Schnittlinie A-B der Fig. 1, Fig. 3 ist eine Schnittdarstellung entsprechend der Schnittlinie C-D der Fig. 1. Fig. 1 is a plan view of a cover grate according to the invention, Fig. 2 is a sectional view taken along line A-B of Fig. 1; FIG. 3 is a sectional view taken along line C-D of FIG. 1.
Der hier dargestellte, aus einem Blechstreifen hergestellte Abdeckrost 1 weist in herkömmlicher Art quer verlaufende Ablauföffnungen 2 auf, die mit Zwischenstegen 3 abwechseln. Die tragenden Längsränder 4 des Rostes sind zu einem geschlossenen Profil eingerollt, das in Fig. 3 als Vierkantprofil gezeigt ist. Es ist aber auch ein Rundprofil denkbar, das herstellungsmäßig gegenüber einem abgekanteten Profil eine weitere Vereinfachung bietet. The cover grate shown here, made from a sheet metal strip 1 has transverse drainage openings 2 in a conventional manner, with intermediate webs 3 alternate. The supporting longitudinal edges 4 of the grate are closed Rolled up profile, which is shown in Fig. 3 as a square profile. It is also a round profile is conceivable, the manufacturing compared to a beveled profile offers a further simplification.
Die Rostfläche wird durch das geschlossene Profil nicht nur durch die äußeren Tragstege 4', sondern auch durch die inneren Abstützstege 4" abgestützt, was die vorerwähnten Vorteile einer -höheren Tragfähigkeit bzw. The grate surface is not only through the closed profile the outer support webs 4 ', but also supported by the inner support webs 4 ", what the aforementioned advantages of a -higher load-bearing capacity or
einer Materialersparnis mit sich bringt. Überdies wird dadurch erreicht, daß sich kein Schmutz mehr in Profil ecken absetzen kann, was der Rostbildung an dem Abdeckrost wesentlich Vorschub leistet.brings a material saving with it. In addition, it is achieved that no more dirt can settle in the profile corners, what the rust formation the cover grating makes a significant advance.
