Beschreibung description
Die Erfindung betrifft einen Abdeckrost nach dem Oberbegriff des The invention relates to a cover grate according to the preamble of
Patentanspruches 1. Claim 1.
Zum Abdecken von Öffnungen in Oberflächen, die begangen und/oder befahren werden sollen, dienen Abdeckroste. Einen wesentlichen Anteil an derartigen Bauwerken bilden Abflussrinnen oder Schächte, die zur Oberflächenentwässerung dienen. Derartige Abdeckroste müssen zum einen stabil sein, zum anderen eine hinreichend große Entwässerungsleistung bieten. Weitere wichtige Punkte liegen im Preis und im Gewicht. To cover openings in surfaces that are to be committed and / or traveled, serve grating. A significant proportion of such structures form gutters or shafts that serve for surface drainage. Such grids must be stable on the one hand, on the other hand offer a sufficiently large drainage performance. Other important points are the price and the weight.
Ein weiterer wichtiger Punkt liegt bei Abdeckrosten, die in von Fußgängern begangenen Flächen liegen, in der Rutschsicherheit. Gerade dann, wenn derartige Abdeckroste aus Kostengründen und aus Gründen der Gewichtsersparnis aus Blechmaterial hergestellt werden, treten hier oftmals Probleme auf. Another important point lies in the anti-slip safety features of the grids on pedestrian areas. Especially when such grids are made for cost reasons and for reasons of weight savings of sheet material, often occur here problems.
Aus der DE 1 856 722 U ist ein Abdeckrost bekannt, bei welchem einander kreuzende Stäbe aus Blechmaterial Kanten aufweisen, die sägezahnförmig ausgebildet sind, um so eine erhöhte Rutschfestigkeit zu bieten. Die Tragfähigkeit derartiger Roste ist begrenzt. From DE 1 856 722 U a cover grate is known, in which intersecting rods made of sheet material have edges that are sawtooth-shaped, so as to provide an increased slip resistance. The carrying capacity of such gratings is limited.
Aus der DE 1 659 147 A oder der DE 1 966 875 U sind Abdeckroste bekannt, bei denen Längsträger mit U-förmigem Querschnitt mit ihren Schenkeln in Schlitzen gelagert sind, welche sich in Querträgern befinden. Die Längsträger stehen über die Querträger hervor. Die Rutschfestigkeit derartiger Abdeckroste ist nicht hinreichend . Der Erfindung liegt die Aufgabe zu Grunde, einen Abdeckrost der eingangs genannten Art dahingehend weiterzubilden, dass bei einfacher Konstruktion eine verbesserte Rutschsicherheit gewährleistet ist. Cover grates are known from DE 1 659 147 A or DE 1 966 875 U, in which longitudinal members are mounted with U-shaped cross-section with their legs in slots, which are located in cross members. The side members protrude above the cross members. The slip resistance of such cover grates is not sufficient. The invention is based on the object, a cover grate of the type mentioned in such a way that with a simple construction improved slip resistance is guaranteed.
Diese Aufgabe wird durch einen Abdeckrost nach Anspruch 1 gelöst. This object is achieved by a cover grate according to claim 1.
Insbesondere wird diese Aufgabe durch einen Abdeckrost zum Abdecken von Schächten, Rinnen oder dergleichen Bauwerken gelöst, umfassend Randschienen, mit den Randschienen verbundene Querträger aus Blechabschnitten und mit den Querträgern verbundene Längsträger. Hierbei sind die Längsträger derart an den Querträgern befestigt, dass obere Trittflächen der Längsträger versenkt oder bündig mindestens zu Trittabschnitten von Oberkanten der Querträger verlaufen. Durch diese sehr einfache Konstruktion wird bewirkt, dass die Trittabschnitte der Querträger, welche ja wiederum aus Blechabschnitten gefertigt sind, eine rutschfeste Oberfläche bilden, wobei die Längsträger wiederum so ausgebildet sein können, dass keine Gefahr des Hängenbleibens (z. B. mit schmalen Absätzen) gegeben ist. In particular, this object is achieved by a cover grille for covering shafts, gutters or similar structures comprising edge rails, with the edge rails connected cross member of sheet metal sections and connected to the cross members longitudinal beams. Here, the longitudinal members are secured to the cross members such that upper tread surfaces of the side members sunk or flush at least to tread portions of upper edges of the cross member. This very simple construction causes the tread portions of the cross member, which in turn are made of sheet metal sections, form a non-slip surface, wherein the side members may in turn be formed so that there is no danger of getting caught (eg with narrow heels) given is.
Die Längsträger weisen vorzugsweise im Wesentlichen U-förmige Querschnitte auf, wobei ihre Schenkel in den Querträgern befestigt sind . Dadurch kann eine hohe Stabilität bei Erhöhung der oben genannten Sicherheit gegenüber einem Hängenbleiben von dünnen Absätzen gewährleistet sein. The longitudinal members preferably have substantially U-shaped cross-sections, with their legs are secured in the cross members. This can ensure a high stability while increasing the above-mentioned security against snagging of thin heels.
Die Randschienen weisen vorzugsweise Schlitze auf, in denen Enden der The edge rails preferably have slots in which ends of the
Querträger stecken. Dies ermöglicht eine einfache aber dennoch stabile Montage. Insbesondere sind hierbei die Randschienen als Blech-Hohlprofile ausgebildet, was Material und Gewicht spart, dennoch aber sehr stabil ist. Cross member stuck. This allows a simple but stable installation. In particular, in this case the edge rails are designed as sheet-hollow profiles, which saves material and weight, but is still very stable.
Die Querträger weisen Schlitze zur Aufnahme der Schenkel der Längsträger auf, wobei diese Schlitze derart ausgebildet sind, dass die Schenkel in diese Schlitze einsetzbar sind . Auch hier wird mit einfachen konstruktiven Maßnahmen eine hohe Stabilität erwirkt. Die Enden der Querträger sind vorzugsweise innerhalb der Randschienen derart abgebogen, dass die Querträger an den Randschienen befestigt sind. Es kann eine stabile Befestigung also ausschließlich aufgrund einer Verformung hergestellt werden, ein Verschweißen ist nicht notwendig. Die Querträger weisen vorzugsweise Anschlagabschnitte vor deren Enden derart auf, dass die Enden in einer definierten Einstecktiefe in die Randschienen einsteckbar sind. Dadurch wird eine exakte Form und Dimensionierung erzielt. The cross members have slots for receiving the legs of the side members, wherein these slots are formed such that the legs are inserted into these slots. Again, a high stability is obtained with simple design measures. The ends of the cross member are preferably bent within the edge rails such that the cross member are attached to the edge rails. It can be made a stable attachment so only due to deformation, welding is not necessary. The cross members preferably have abutment portions in front of their ends in such a way that the ends can be inserted into the edge rails in a defined insertion depth. This achieves an exact shape and dimensioning.
Die Randschienen weisen vorzugsweise Auflageflächen zum Auflegen auf entsprechende Abschnitte der Bauwerke auf und Unterkanten der Enden der Querträger sind so geformt, dass sie auf den Innenflächen der Auflageflächen aufliegen. Dadurch wird eine hohe Laststabilität erreicht. The edge rails preferably have bearing surfaces for laying on corresponding sections of the structures and lower edges of the ends of the cross members are shaped so that they rest on the inner surfaces of the bearing surfaces. This achieves high load stability.
Die Trittabschnitte der Querträger weisen gegenüber abgerundeten The tread portions of the cross member have opposite rounded
Übergangsbereichen zwischen den Schenkel n und den Trittflächen der Transition areas between the legs n and the treads of
Längsträger scharfkantige Eingriffsecken auf. Diese sind natürlich nicht so scharfkantig, dass Verletzungen von Personen (oder Fahrradreifen) auftreten, sind aber doch„so eckig", dass eine erhöhte Rutschfestigkeit garantiert wird. Longitudinal beams sharp edged engagement corners on. These are of course not so sharp that injuries to people (or bicycle tires) occur, but are "square" so that increased slip resistance is guaranteed.
Es sind vorzugsweise Halteklammern vorgesehen, die zum Befestigen der Abdeckroste im Bauwerk mit den Randschienen verbunden sind. Dadurch ist eine einfache aber doch hinreichend stabile Montage des Abdeckrostes auf einem Bauwerk sichergestellt. Die Halteklammern weisen vorzugsweise obere There are preferably provided retaining clips, which are connected for securing the cover grates in the building with the edge rails. This ensures a simple but sufficiently stable installation of the grating on a building. The retaining clips preferably have upper
Federabschnitte auf, mit denen sie in Öffnungen der Randschienen unter Spannung einsetzbar und in den Randschienen vorzugsweise formschlüssig festsetzbar sind. Der Zusammenbau gestaltet sich somit sehr einfach. Spring sections, with which they can be used under tension in openings of the edge rails and preferably in the edge rails form-fitting fixable. The assembly is thus very simple.
Die Randschienen weisen weiterhin nach unten ragende Stockelemente auf, die zum Einsetzen in korrespondierende Ausnehmungen im Bauwerk und zum Verhindern einer Längsverschiebung des Abdeckrostes gegenüber dem Bauwerk ausgebildet sind. Diese Stockelemente können also sehr einfach hergestellt werden. The edge rails also have downwardly projecting floor elements, which are designed for insertion into corresponding recesses in the building and to prevent longitudinal displacement of the cover against the building. So these floor elements can be made very easily.
Die Randschienen weisen außenseitige Zugangsöffnungen derart auf, dass die Enden der Querträger von außen für Werkzeuge zum Verbinden der Querträger mit den Randschienen zugänglich sind. Durch diese einfache konstruktive Maßnahme werden somit die Abdeckroste sehr leicht herstellbar. The edge rails have outside access openings in such a way that the ends of the cross member are accessible from the outside for tools for connecting the cross member to the edge rails. By this simple constructional measure thus the cover grids are very easy to produce.

In der nachfolgenden Beschreibung werden gleiche und gleich wirkende Teile mit denselben Bezugsziffern bezeichnet. In the following description, like and like parts are designated by the same reference numerals.
Wie aus den Abbildungen hervorgeht, sind Randschienen 10, 10λ vorgesehen, die durch Querträger 20 miteinander verbunden sind. Die Querträger 20 weisen Enden 23, 23λ auf, welche in Schlitzen 11 der Randschienen 10, 10λ stecken. As is apparent from the figures, edge rails 10, 10 λ are provided, which are interconnected by cross member 20. The cross member 20 have ends 23, 23 λ , which stuck in slots 11 of the edge rails 10, 10 λ .
Die Querträger 20 wiederum weisen Schlitze 24 auf, in welchen Schenkel 32, 32λ von Längsträgern 30 eingepresst sind, die einen U-förmigen Querschnitt (wie ein umgekehrtes U) aufweisen. The cross members 20 in turn have slots 24 in which legs 32, 32 are pressed λ of longitudinal members 30, which have a U-shaped cross section (such as an inverted U).
Zwischen jeweils zwei von diesen Längsträgern 30 stehen Trittabschnitte 21, welche Abschnitte der Oberkante 22 eines jeden Querträgers sind, über obere Trittflächen 31 der Längsträger hervor, wie dies insbesondere in Fig. 4 zu sehen ist. Dadurch ist gewährleistet, dass die Querträger 20 bzw. deren Oberkanten 22 mit den Trittabschnitten 21 eine sehr rutschfeste Oberfläche des Abdeckrostes bilden. Andererseits wird durch die Längsträger 30 bzw. deren obere Trittflächen 31 sichergestellt, dass auch bei sehr schmalen Absätzen ein„Einbrechen" in die Entwässerungsöffnungen kaum passieren kann. Between each two of these longitudinal members 30 are tread portions 21, which are portions of the upper edge 22 of each cross member, above upper treads 31 of the side members out, as can be seen in particular in Fig. 4. This ensures that the cross member 20 and its upper edges 22nd form a very non-slip surface of the cover with the tread portions 21. On the other hand, it is ensured by the longitudinal members 30 and their upper treads 31 that even with very narrow steps a "break-in" in the drainage openings can hardly happen.
Die Querträger 20 weisen weiterhin an den zwischen jeweils zwei Längsträgern nach oben hervorstehenden Trittabschnitten 21 Eingriffsecken 27 auf, die auch dann, wenn die Trittabschnitte 21 im Wesentlichen bündig zu den oberen The cross member 20 further have at the between each two longitudinal members upwardly projecting tread portions 21 engagement corners 27, which also when the tread portions 21 is substantially flush with the upper
Trittflächen 31 der Längsträger 30 verlaufen, noch eine rutschhemmende Wirkung zeigen, da die Schenkel 32, 32λ in ihren Übergangsbereichen 33, 33λ zur oberen Trittfläche 31 abgerundet sind und somit ein gewisser Hohlraum gebildet wird, in welchen eine elastische Schuhsohle eindringen und sich mit den Eingriffsecken 27 „festhängen" kann. Treads 31 of the longitudinal members 30 extend, still show a slip-resistant effect, since the legs 32, 32 λ in their transition regions 33, 33 λ to the upper tread 31 are rounded and thus a certain cavity is formed, in which an elastic shoe sole penetrate and with the engagement corners 27 "hang" can.
Wie weiter oben bereits erwähnt, sind die Enden 23, 23λ der Querträger 20 in die Schlitze 11 der Randschienen 10, 10λ eingesteckt. Diese Randschienen 10, 10λ sind wiederum derart als teilweise geschlossener Hohlkörper gebogen, dass eine untere Auflagefläche 12 gebildet ist, mit welcher die Randschienen 10, 10λ auf dem Bauwerk (dort auf einer Zarge) aufliegen. Diesen Auflageflächen 12 im Inneren der Randschiene 10, 10λ gegenüber sind Innenflächen 13 gebildet, auf welchen im montierten Zustand wiederum Unterkanten 26 der Querträger 20 bzw. deren Enden 23, 23λ aufliegen. Dadurch ist eine maximale Stabilität As already mentioned above, the ends 23, 23 are inserted λ of the cross member 20 in the slots 11 of the edge rails 10, 10 λ . These edge rails 10, 10 λ are in turn bent as a partially closed hollow body, that a lower support surface 12 is formed, with which the edge rails 10, 10 λ on the building (there on a frame) rest. These bearing surfaces 12 in the interior of the edge rail 10, 10 λ opposite inner surfaces 13 are formed, on which in turn rest in the mounted state lower edges 26 of the cross member 20 and the ends 23, 23 λ . This provides maximum stability
gewährleistet. guaranteed.
Die Randschienen 10, 10λ weisen außenseitig Zugangsöffnungen 16, 16λ auf, über welche mittels eines Werkzeugs die Enden 23, 23λ der Querträger 20 derart verbogen werden können, dass die Querträger 20 in den Randschienen 10, 10λ befestigt sind. Hierzu trägt weiterhin bei, dass die Querträger 20 The edge rails 10, 10 λ have outside access openings 16, 16 λ , over which by means of a tool, the ends 23, 23 λ of the cross member 20 can be bent so that the cross member 20 in the edge rails 10, 10 are fixed λ . This contributes further that the cross member 20
Anschlagabschnitte 25 aufweisen, mit welchen die Querträger 10, 10λ an den Rändern der Schlitze 11 aufstehen, so dass bei einem Umbiegen der Enden 23, 23λ ein wackelfreier Sitz der Querträger 20 in den Randschienen 10, 10λ gewährleistet ist. Stop sections 25 have, with which the cross member 10, 10 λ stand up at the edges of the slots 11, so that when bending the ends 23, 23 λ a wobble-free fit of the cross member 20 in the edge rails 10, 10 λ is guaranteed.
Weiterhin weisen die Randschienen 10, 10λ Öffnungen 14 (siehe Fig. 7) auf, in welche Halteklammern 40 mit oberen Federabschnitten 41 eingesetzt werden können, welche jeweils einen Eingriffsvorsprung 43 aufweisen. Der Furthermore, the edge rails 10, 10 have λ openings 14 (see Fig. 7), in which retaining clips 40 can be used with upper spring portions 41, each having an engagement projection 43. Of the
Eingriffsvorsprung 43 inseriert in entsprechende Ausnehmungen der Randschienen 10, 10\ so dass die Halteklammer 40 in die Randschiene 10, 10λ bzw. deren Öffnung 14 hineingesteckt und hineingehebelt werden kann, bis sie dort einschnappt. Engagement projection 43 inserted into corresponding recesses of Edge rails 10, 10 \ so that the retaining clip can be inserted in the edge rail 10, 10 λ or its opening 14 and 40 in leveraged until it snaps there.
In der montierten Position ragt dann ein Klemmabschnitt 42 von der Randschiene 10, 10λ nach unten, der so ausgebildet ist, dass er sich entweder an einer Wand des Bauwerks oder in einer dort vorgesehenen Öffnung festhängt und den Abdeckrost auf dem Bauwerk befestigt. In the mounted position then projects a clamping portion 42 of the edge rail 10, 10 λ down, which is designed so that it hangs either on a wall of the building or in an opening provided there and fixed the cover grid on the building.
Die Randschienen 10, 10λ weisen weiterhin Stockelemente 15 auf, siehe Fig. 2, 3 und 4, die in entsprechende Ausnehmungen des Bauwerkes eingreifen, so dass eine Längsverschiebung des Rostes auf dem Bauwerk sicher verhindert werden kann.
