Description

ABDECKUNG AUS MEHREREN, INEINANDER EINGESETZTEN ROSTEN  COVER OF MULTIPLE, INPUT ROSTS
Beschreibung description
Die Erfindung betrifft eine Abdeckung für Rinnen, Schächte oder dergleichen The invention relates to a cover for gutters, manholes or the like
Bauwerke nach dem Oberbegriff des Patentanspruches 1. Structures according to the preamble of claim 1.
Im Außen- oder Innenbereich sind oftmals Öffnungen derart zu verschließen, dass man sie gefahrlos überschreiten oder überfahren kann. In vielen Fällen, z. B. zur Entwässerung von Oberflächen weisen derartige Abdeckungen Öffnungen auf, in welche das Oberflächenwasser eintreten kann, um dann abgeführt zu werden. Im einfachen Fall werden derartige Abdeckungen als Roste aus Blech gebogen, die mit Schlitzen und Stegen versehen sind. Die Stege weisen Oberflächen und Seitenflächen auf, die gegenüber der Oberfläche abgekantet sind. Derartige Roste werden aus einem einzigen Blechstreifen hergestellt, in dem das Material zwischen den Stegen durchtrennt und derart nach unten gebogen wird, dass die Seitenflächen entstehen. Die Höhe der Seitenfläche beträgt somit den halben Abstand zwischen zwei Stegen bzw. die halbe Breite der Schlitze. Da die Breite der Schlitze begrenzt ist, steht somit nur eine bestimmte Maximalhöhe der Seitenflächen zur Verfügung, was die Stabilität der Roste begrenzt. Um deren Stabilität zu erhöhen, muss ein stärkeres Material gewählt werden, was wiederum die Kosten für derartige Roste erheblich erhöht. Ein solcher Rost ist beispielsweise aus der WO 2008/052599 AI bekannt. In the outer or inner area, openings are often to be closed in such a way that they can be safely crossed or run over. In many cases, for. As for drainage of surfaces, such covers have openings into which the surface water can enter, to then be dissipated. In the simple case of such covers are bent as grates made of sheet metal, which are provided with slots and webs. The webs have surfaces and side surfaces which are folded relative to the surface. Such grates are made of a single sheet metal strip in which the material is severed between the webs and bent down so that the side surfaces arise. The height of the side surface is thus half the distance between two webs or half the width of the slots. Since the width of the slots is limited, thus only a certain maximum height of the side surfaces is available, which limits the stability of the grates. To increase their stability, a stronger material must be selected, which in turn significantly increases the cost of such grates. Such a grate is known for example from WO 2008/052599 AI.
Der Erfindung liegt die Aufgabe zugrunde, eine Abdeckung der eingangs genannten Art dahin gehend weiterzubilden, das eine erhöhte Stabilität ohne Erhöhung der Materialstärke erzielbar ist. The invention has the object of developing a cover of the type mentioned so that an increased stability without increasing the material thickness can be achieved.
Diese Aufgabe wird durch eine Abdeckung nach Anspruch 1 gelöst. Insbesondere wird diese Aufgabe dadurch gelöst, dass mindestens ein zweiter Rost vorgesehen ist, dessen Stege in die Schlitze des ersten Rostes eingesetzt sind. Dies bedeutet, dass jeder der beiden Roste (wenn man zunächst von nur zwei Rosten ausgeht) die doppelte Schlitzbreite aufweisen kann, was wiederum dazu führt, dass die Höhe der Seitenflächen eines jeden Steges genau doppelt so hoch ist wie bei der„normalen" Schlitzbreite. Dadurch kann trotz geringer Schlitzbreite (wie dies vorgeschrieben ist) bei gleicher Materialstärke eine erhöhte Stabilität erzielt werden. This object is achieved by a cover according to claim 1. In particular, this object is achieved in that at least a second grate is provided, the webs are inserted into the slots of the first grate. This means that each of the two grates (assuming initially only two grates) the double slit width, which in turn means that the height of the side surfaces of each ridge is exactly twice as high as the "normal" slit width, thus allowing increased stability despite the narrow slit width (as prescribed) with the same material thickness ,
Vorzugsweise ist der erste Rost mit dem zweiten Rost und gegebenenfalls weiteren Rosten verbunden und zwar vorzugsweise unlösbar verbunden. Dadurch ergibt sich eine in einem Stück handhabbare Abdeckung. Preferably, the first grate is connected to the second grate and possibly further grates, and preferably connected undetachably. This results in a manageable in one piece cover.
Wenn der erste Rost mit dem zweiten Rost und gegebenenfalls weiteren Rosten formschlüssig verbunden ist, so kann mit geringem Arbeitsaufwand ein einstückiges Bauteil geschaffen werden. If the first grate is positively connected to the second grate and optionally further grates, it can be created with little effort a one-piece component.
Vorzugsweise wird der erste Rost mit dem zweiten Rost und gegebenenfalls weiteren Rosten durch randseitige Falze verbunden. Dies ergibt ein sehr kompaktes Bauteil, da die Roste ohnehin mit ihren Rändern auf entsprechenden Zargen oder Oberrändern der abzudeckenden Schächte oder Bauwerke aufliegen. Preferably, the first grate is connected to the second grate and optionally further grates by edge-side folds. This results in a very compact component, since the grates rest anyway with their edges on corresponding frames or upper edges of the shafts or structures to be covered.
Vorzugsweise sind die Stege der Roste derart gebogen, dass ihre Oberflächen in einer Ebene verlaufen. Dies verringert die Verletzungsgefahr und verbessert das Aussehen der Roste. Preferably, the webs of the grates are bent so that their surfaces extend in a plane. This reduces the risk of injury and improves the appearance of the grates.
Eine besonders hohe Stabilität ergibt sich dann, wenn mindestens einer der Roste randseitige, nach unten ragende Randstreifen mit im Wesentlichen senkrechten Schlitzen aufweist, in welche die Seitenflächen der Stege eingehängt sind . Durch die Abstützung der Stege am Rand wird die Stabilität der Roste insgesamt erheblich erhöht. A particularly high stability is obtained when at least one of the grates edge-side, downwardly projecting edge strips having substantially vertical slots, in which the side surfaces of the webs are mounted. By supporting the webs on the edge, the stability of the grates is significantly increased overall.
Vorzugsweise weist nur einer der Roste randseitige Auflagebänder auf, die unter Zwischenlage von randseitigen Auflagebändern aller weiteren Roste U-förmig gebogen sind, so dass sie die„einlagigen" Auflagebänder der anderen Roste umschließen. Dadurch wird in besonders kostengünstiger Weise eine formschlüssige Verbindung aller Roste miteinander erzielt. Preferably, only one of the grates has edge-side support bands, which are bent in an U-shape with the interposition of marginal support bands of all further gratings, so that they enclose the "single-layer" support bands of the other gratings, thereby providing a positive connection of all the grates with one another in a particularly cost-effective manner achieved.
Die bisher beschriebenen Ausführungsformen der Erfindung betreffen einen Rost, der mit seinen Auflagebändern auf dem Rand einer Rinne aufliegt. Die hier vorliegende Erfindung ist aber auch für Roste geeignet, die zwischen Zargen einer Rinne eingelegt werden. Hierbei weisen die Roste C-förmige oder hakenförmige, nach innen offene randseitige Falze auf, in welchen die Stege aufgestützt sind. Ansonsten bleiben die prinzipiellen Konstruktionsmerkmale, also die formschlüssige Verbindung mehrerer Roste gleich. The embodiments of the invention described so far relate to a grate which rests with its support bands on the edge of a groove. The present invention is also suitable for gratings that are inserted between frames of a gutter. Here, the grates C-shaped or hook-shaped, inwardly open marginal folds in which the webs are supported. Otherwise, the basic design features, ie the positive connection of multiple grids remain the same.

Nachfolgend wird anhand der Fig. 1 und 2 eine Ausführungsform der Erfindung erläutert. Hereinafter, an embodiment of the invention will be explained with reference to FIGS. 1 and 2.
In Fig. 1 B ist ein erster Rost gezeigt, der aus einem einzigen Blechstück durch Rollformen bzw. Stanzen hergestellt ist. Dieser erste Rost 10 weist Stege 12 auf, die durch Schlitze 11 getrennt sind. Jeder Steg 12 weist eine Oberfläche auf, die mit Noppen zur Verbesserung der Rutschfestigkeit beim Betreten versehen ist. Von den Oberflächen 13 nach unten gerichtet, weisen die Stege 12 Seitenfalze 14, 14 ' auf, die mit Endkrallen 19 (Fig. 7) in Schlitze 17 eingreifen, welche in Randstreifen 16, 16 ' eingestanzt sind, sodass jede Seitenfläche 14, 14 ' mit ihren Enden in den In Fig. 1 B, a first grate is shown, which is made of a single piece of sheet metal by roll forming or punching. This first grid 10 has webs 12 which are separated by slots 11. Each land 12 has a surface provided with nubs for improving slip resistance upon entry. Pointed downwardly from the surfaces 13, the webs 12 have side folds 14, 14 ' which engage with end claws 19 (Fig. 7) in slots 17 which are stamped in edge strips 16, 16 ' such that each side face 14, 14 ' with their ends in the
Randstreifen 16, 16 ' abgestützt ist. Die Oberflächen 13 sind weiterhin mit jeweils einem oberen Schenkel eines U-förmigen Falzes 15 verbunden, der - nach unten abgekantet - in die Randstreifen 16, 16 ' übergeht. Edge strip 16, 16 'is supported. The surfaces 13 are further connected to a respective upper leg of a U-shaped fold 15, which - folded down - in the edge strips 16, 16 ' passes.
In Fig. 1 B ist zu sehen, dass die Schlitze 17 in genau der doppelten Anzahl vorgesehen sind, wie die Stege 12. In diese Schlitze 17 können nun Seitenflächen 24, 24 ' von Stegen 22 eines zweiten Rostes 20 (Fig. 1 A) eingesetzt werden, sodass dann der fertige Rost gemäß Fig. 1 C entsteht. Dieser fertige Rost weist also abwechselnd Stege 12 und 22 eines ersten Rostes 10 bzw. zweiten Rostes 20 auf. In FIG. 1B, it can be seen that the slots 17 are provided in exactly twice the number as the webs 12. Side surfaces 24, 24 ' of webs 22 of a second grate 20 (FIG. 1A) can now be inserted into these slots 17. are used, so that then the finished rust as shown in FIG. 1 C is formed. This finished grate has therefore alternately webs 12 and 22 of a first grate 10 and second grate 20.
Weiterhin sind Auflagebänder 28, 28 ' des zweiten Rostes 20 zwischen den Furthermore, support belts 28, 28 'of the second grate 20 between the
Seitenflächen der U-förmige Falze 15, 15 ' eingeklemmt und Endkrallen 29 der Side surfaces of the U-shaped folds 15, 15 ' clamped and end claws 29 of the
Seitenflächen 24, 24 ' in Schlitze 17 der Randstreifen 16, 16 ' des ersten Rostes 10 eingehängt. Side surfaces 24, 24 ' in slots 17 of the edge strips 16, 16 ' of the first grate 10 mounted.
Die Vorteile dieser Konstruktion werden nachfolgend anhand der Fig. 3 bis 5 erläutert. The advantages of this construction will be explained below with reference to FIGS. 3 to 5.
In Fig. 3 ist stark schematisiert ein Blech gezeigt, das zunächst in einer Ebene verläuft und dann im Bereich des Pfeils in Fig. 3 durchtrennt wird. Daraufhin werden die Blechabschnitte wie in Fig. 3 gezeigt nach unten abgekantet, sodass eine Reihe von Stegen mit dazwischen liegenden sehr breiten Schlitzen entsteht. In Fig. 4 ist eine solche Anordnung gezeigt, wobei die dortigen Stege 22 mittig zwischen die Stege 12 des Rostes 10 aus Fig. 5 eingesetzt werden. Dadurch können die Seitenflächen 14, 14 ' bzw. 24, 24 ' doppelt so hoch ausgebildet werden, wie bei einem Rost, der nur aus einem Teilstück besteht. In Fig. 3 is a highly schematic sheet shown, which first extends in a plane and is then severed in the region of the arrow in Fig. 3. Thereupon become the sheet metal sections as shown in Fig. 3 bent down, so that a series of webs with intervening very wide slots is formed. In Fig. 4 such an arrangement is shown, wherein the local webs 22 are inserted centrally between the webs 12 of the grate 10 of Fig. 5. This allows the side surfaces 14, 14 ' and 24, 24 ' are formed twice as high, as in a grate, which consists of only one piece.
In den Fig. 6 und 7 sind Schnitte entlang der Linien VI-VI bzw. VII-VII aus Fig. 5 gezeigt. Hieraus wird ersichtlich, dass der erste Rost 10 seitlich Falze 15 aufweist, welche einerseits U-förmig umgebogen und dann andererseits nach unten zur Bildung der Randstreifen 16 abgekantet sind. Diese Randstreifen 16 weisen Schlitze 17 auf, in welche Endkrallen 19 der Seitenflächen 14 eingreifen, sodass die Stege 12 des ersten Rostes 10 mit ihren Seitenflächen 14 in dem Randstreifen 16 abgestützt sind. In Figs. 6 and 7, sections along the lines VI-VI and VII-VII of Fig. 5 are shown. It can be seen that the first grid 10 has laterally folds 15, which on the one hand bent in a U-shape and then on the other hand bent down to form the edge strips 16. These edge strips 16 have slots 17, in which end claws 19 of the side surfaces 14 engage, so that the webs 12 of the first grate 10 are supported with their side surfaces 14 in the edge strip 16.
Weiterhin umgreifen die Falze 15 Auflagebänder 28 des zweiten Rostes 20, der also keine Falze 15 und Randstreifen 16 aufweist. Durch diese Konstruktion ist einerseits eine sichere Verbindung zwischen dem ersten Rost 10 und dem zweiten Rost 20 durch Formschluss gewährleistet, andererseits ergibt sich die oben bereits erläuterte Furthermore, the folds 15 surround support bands 28 of the second grate 20, which therefore has no folds 15 and edge strips 16. On the one hand, this construction ensures a secure connection between the first grate 10 and the second grate 20 by positive engagement, on the other hand, the above already explained
Stabilitätserhöhung durch höhere Seitenflächen 14, 14 ' . Stability increase by higher side surfaces 14, 14 ' .
Das soeben erläuterte Prinzip des„Ineinanderschachteins" von zwei Rosten kann auch auf eine höhere Zahl von Rosten erweitert werden. Dies ist in den Fig. 8 bis 11 gezeigt. The above-explained principle of "nesting" of two pillars can also be extended to a higher number of pillars, as shown in Figures 8-11.
Bei der Ausführungsform nach Fig. 8 sind neben einem ersten Rost 10 und einem zweiten Rost 20 drei weitere Roste 30 bis 32 schematisiert gezeigt. Diese Roste können dann - wie dies in Fig. 9 gezeigt ist - so ineinander„gestapelt" werden, dass eine vollständig geschlossene Abdeckung entsteht, die aber„nur" aus Blechformteilen hergestellt ist, die aber eine außerordentlich hohe Stabilität aufweist. In the embodiment according to FIG. 8, in addition to a first grate 10 and a second grate 20, three further grates 30 to 32 are shown schematically. These grates can then - as shown in Fig. 9 - be "stacked" in one another, that a completely closed cover is formed, but "only" made of sheet metal parts, but has an extremely high stability.
Bei den in den Fig. 10 und 11 gezeigten Ausführungsform sind ein erster Rost 10, ein zweiter Rost 20 und ein dritter Rost 30 ineinander gesteckt, sodass relativ schmale Schlitze 11 entstehen, wie dies ab und an gewünscht ist. Darüber hinaus ist die Stabilität dieser Anordnung ebenfalls besonders hoch. In the embodiment shown in FIGS. 10 and 11, a first grate 10, a second grate 20 and a third grate 30 are inserted into each other, so that relatively narrow slits 11 arise, as is desired from time to time. In addition, the stability of this arrangement is also particularly high.
In Fig. 1 sowie in den Figuren 6 und 7 wurden Roste beschrieben, die mit ihren Auflagebändern 18, 18 '; 28, 28 ' auf Rändern einer Rinne aufliegen. In den Figuren 12 und 13 sind schematisiert Roste gezeigt, die zwischen Zargen einer Rinne liegen. Hierfür sind die Falze 15 C-förmig bzw. hakenförmig ausgebildet und definieren die Dicke der Roste 10, 20. Die Stege 22 bzw. deren Seitenflächen 24, 24 ' ragen mit ihren Endkrallen 29 in die hakenförmigen Falze 15 hinein und stützen sich dort ab. Der hierdurch erreichte Erfolg ist derselbe wie bei der zuvor gezeigten In Fig. 1 and in Figures 6 and 7 grids have been described, with their support bands 18, 18 ' ; 28, 28 ' rest on edges of a gutter.
