Definitions
- the invention relates to a ladder-like grate made of sheet steel for drainage channels, which is provided with longitudinal edges which are raised and angled to the opposite longitudinal edge and with supporting webs arranged between the longitudinal edges, each of which is separated from each adjacent supporting web by an inlet slot which one in the direction of the Elevation of the longitudinal edges beaded and parallel to each supporting web in an inclined inlet surface has edge.
- Drainage channels are designed to drain traffic areas. They absorb accumulated rainwater in a line and pass it on. Drainage channels are formed by lining up channel elements, which are elongated drainage objects with a trough-shaped cross-section, which are covered by grids or lids. The drainage channels are classified according to their installation location.
- a grating force of 15 kN is applied to gratings for traffic areas that are only used by pedestrians and cyclists - class A-; on grates for sidewalks, pedestrian areas, car parking areas and car parking decks - class B -, a test force of 125 kN; on gratings for curbs in streets and pedestrian streets, guiding and hard shoulder, parking areas - class C -, a test force of 250 kN.
- the low-force test is sufficient for grates of the type mentioned at the beginning; the medium power only conditionally; no longer the one for heavy loads.
- Cast iron grates are therefore used for medium and large loads. Cast iron grates are heavy and expensive compared to grates of the type mentioned at the beginning. They are also brittle, so that there is a risk of breakage when handling - transport, installation, installation and removal for cleaning - as well as with asymmetrical loading.
- the road grate described and shown in CH-A-338 790 consists of a single iron sheet into which grate openings are made.
- the rust is stiffened.
- One type of mounting is that a U-shaped rib is welded beneath every second supporting web, the ends of which are widened in a fork shape so that they can reinforce the edge of the grate.
- the end faces of the grate are reinforced by a zigzag-shaped sheet.
- the grate described and shown in DE-AZ-2 423 305 has longitudinal edges which are rolled into a closed profile. Support webs are provided between the longitudinal edges, each of which is separated from each adjacent support web by an inlet slot. Each inlet slot has an edge on which runs parallel to each support web into an inclined inlet surface.
- the invention solves the problem of designing a grate from sheet steel for drainage channels so that it can withstand increased loads.
- the advantages achieved by the invention are essentially to be seen in the fact that the grate not only withstands all loads, including those of groups B and C, but is light and nevertheless unbreakable.
- the grate according to the invention is additionally stabilized in the transverse direction by the support webs and in the longitudinal direction by the side webs of the inner grate.
- it is provided to assign an outer grate of a certain sheet thickness to inner grates of different sheet thickness so as to adapt the load-bearing capacity to the loads.
- the limit in the possible variations is only the back width of the support bar of the inner grate, which is placed in the support bar of the outer grate.
- the outer and inner grate can be produced in a known manner from sendzimier galvanized steel sheet, from steel sheet which is hot-dip galvanized after being deformed, or from stainless steel sheet. It is advantageous to stamp stop lugs on the surface in the usual way for anti-slip protection.
- the grate for drainage channels chosen as an exemplary embodiment consists of an outer grate 1 and an inner grate 2 fastened in the outer grate.
- the outer grate 1 has two longitudinal edges 11, each of which consists of a raised surface 12 and a surface 13 angled to the opposite longitudinal edge.
- Support webs 14 are provided between the longitudinal edges 11.
- the supporting webs 14 are provided with stop knobs 15 projecting outwards.
- An inlet slot 16 is provided between adjacent supporting webs 14.
- Each inlet slot 16 has an edge 18 which is beaded in the direction of the raised surface 12 and merges parallel to each supporting web 14 into an inclined inlet surface 17.
- the inner grate 2 is formed by two side webs 21 and by support webs 22 formed between the side webs 21.
- the inner grid 2 is held with its side webs 21 between the angled longitudinal edges 11 of the outer grid 1.
- the support webs 22 of the inner grate 2 rest on the support webs 14 of the outer grate 1.
- the side webs 21 of the inner grate 2 are each formed from a raised edge strip of one of the steel sheets.
- the support webs 22 are designed in the manner of an inverted channel. In cross section, an inverted U-profile is created. With their back 23, the support webs 22 of the inner grate 2 lie against the support webs 14 of the outer grate 1 on the inside. With the end faces 24 of their side walls 25, the supporting webs 22 abut the side webs 21. The back 23 of each support web 22 merges into the side webs 21 at the end faces.
- the support webs 22 of the inner grating 2 are made of the same steel sheet as the side webs 21, a support web 22 of the inner grate 2 can only rest against every second support web 14 of the outer grate 1 at a predetermined distance of the inlet slots 16 of the outer grate 1 . If the inlet slits 16 are arranged at a greater distance from one another in the outer grate 1 or the raised surface 12 is made shorter, the principle that both the outer grate 1 and the inner grate 2 are each made from a steel sheet can still be made on each supporting web 14 of the outer grate 1, a supporting web 22 of the inner grate 2 is created.
- the load capacity of the grate can also be increased in that a stronger steel sheet is used for the inner grate 2, whereby both the side webs 21 and the support webs 22 receive thicker side walls, which increases the stability.
- the inner grate 2 is held in the outer grate 1 once with its side webs 21 between the angled longitudinal edges 11, and secondly with its support webs 22 in contact with the support webs 14 between the angled inlet surfaces 17.
- the inner grate 2 is held immovably in the outer grate 1, without additional attachment.
- the easiest way to produce the grate is using the following method: in a steel sheet provided for the outer grate 1, depressions and the stop lugs 15 are pressed in the first operation. Separately, the outlines of the side webs 21 and the support webs 22 are cut and cut into a steel sheet provided for the inner grate 2 at the same time. In the second step, the troughs are cut in the steel sheet provided for the outer grate 1 and the end pieces are cut. Separately, the side walls 25 of the supporting webs 22 of the inner grate 2 are raised at the same time. In the third step, the inlet surfaces 16 are raised on the supporting webs 14 and the longitudinal edges 11 of the outer grate 1.
- the side webs 21 of the inner grate 2 are raised at the same time.
- the inner grate 2 is then inserted into the outer grate 1, so that the supporting webs 22 lie in the supporting webs 14.
- the longitudinal edges 11 of the outer grate 1 are then angled and pressed around the side webs 21 of the inner grate 2. The above operations are carried out on the same press in a step tool.

Abstract
Description
Die Erfindung bezieht sich auf einen leiterartigen Rost aus Stahlblech für Entwässerungsrinnen, der mit hochgestellten und zur gegenüberliegenden Längskante abgewinkelten Längskanten und mit zwischen den Längskanten angeordneten Tragstegen versehen ist, von denen jeder von jedem benachbarten Tragsteg durch einen Einlaufschlitz getrennt ist, der einen in Richtung der Hochstellung der Längskanten gesickten und parallel zu jedem Tragsteg in eine schräge Einlauffläche übergehenden Rand aufweist.The invention relates to a ladder-like grate made of sheet steel for drainage channels, which is provided with longitudinal edges which are raised and angled to the opposite longitudinal edge and with supporting webs arranged between the longitudinal edges, each of which is separated from each adjacent supporting web by an inlet slot which one in the direction of the Elevation of the longitudinal edges beaded and parallel to each supporting web in an inclined inlet surface has edge.
Entwässerungsrinnen sind zur Entwässerung von Verkehrsflächen bestimmt. Sie nehmen anfallendes Niederschlagswasser linienförmig auf und leiten es weiter. Entwässerungsrinnen werden gebildet durch Aneinanderreihen von Rinnenelementen, das sind längliche Entwässerungsgegenstände mit muldenförmigem Querschnitt, die durch Roste oder Deckel abgedeckt sind. Die Entwässerungsrinnen sind nach ihrer Einbaustelle klassifiziert.Drainage channels are designed to drain traffic areas. They absorb accumulated rainwater in a line and pass it on. Drainage channels are formed by lining up channel elements, which are elongated drainage objects with a trough-shaped cross-section, which are covered by grids or lids. The drainage channels are classified according to their installation location.
Auf die Rinnenelemente sowie die Roste und Deckel werden bei einer Prüfung Kräfte aufgebracht, die nach ihrem Einsatzort entsprechend ihrer Klassifizierung unterschiedlich groß sind. Auf Roste für Verkehrsflächen, die ausschließlich von Fußgängern und Radfahrern benutzt werden - Klasse A-, wird eine Prüfkraft von 15 kN aufgebracht ; auf Roste für Gehwege, Fußgängerbereiche, PKW-Parkflächen und PKW-Parkdecks - Klasse B -, eine Prüfkraft von 125 kN ; auf Roste für Bordrinnen in Straßen und Fußgängerstraßen, Leit- und Seitenstreifen, Parkflächen - Klasse C -, eine Prüfkraft von 250 kN. Der Prüfung mit geringer Kraft genügen Roste der eingangs genannten Art ; der mittlerer Kraft nur noch bedingt ; nicht mehr der für große Belastung. Dies rührt daher, weil im Übergangsbereich vom Einlaufschlitz in die Längskante nur das Blech ohne jegliche Versteifung trägt. Für die Anwendung bei mittlerer und großer Belastung werden daher Roste aus Gußeisen verwendet. Roste aus Gußeisen sind aber im Vergleich zu Rosten der eingangs genannten Art schwer und teuer. Sie sind außerdem spröde, sodaß sowohl beim Hantieren - Transport, Einbau, Ein- und Ausbau zum Säubern - als auch bei unsymmetrischer Belastung Bruchgefahr besteht.In a test, forces are applied to the channel elements as well as the grids and lids, which are of different sizes depending on their location according to their classification. A grating force of 15 kN is applied to gratings for traffic areas that are only used by pedestrians and cyclists - class A-; on grates for sidewalks, pedestrian areas, car parking areas and car parking decks - class B -, a test force of 125 kN; on gratings for curbs in streets and pedestrian streets, guiding and hard shoulder, parking areas - class C -, a test force of 250 kN. The low-force test is sufficient for grates of the type mentioned at the beginning; the medium power only conditionally; no longer the one for heavy loads. This is because, in the transition area from the inlet slot to the longitudinal edge, only the sheet is supported without any stiffening. Cast iron grates are therefore used for medium and large loads. Cast iron grates are heavy and expensive compared to grates of the type mentioned at the beginning. They are also brittle, so that there is a risk of breakage when handling - transport, installation, installation and removal for cleaning - as well as with asymmetrical loading.
Der in der CH-A-338 790 beschriebene und dargestellte Straßenrost besteht aus einem einzigen Eisenblech in welches Rostöffnungen eingebracht sind. Der Rost ist versteift. Eine Art der Versteigung besteht darin, daß unterhalb jedes zweiten Tragstegs eine U-förmige Rippe angeschweißt ist, deren Enden gabelförmig aufgeweitet sind, damit sie den Rand des Rosts verstärken können. Die Stirnseiten des Rosts sind durch ein zickzackförmiges Blech verstärkt.The road grate described and shown in CH-A-338 790 consists of a single iron sheet into which grate openings are made. The rust is stiffened. One type of mounting is that a U-shaped rib is welded beneath every second supporting web, the ends of which are widened in a fork shape so that they can reinforce the edge of the grate. The end faces of the grate are reinforced by a zigzag-shaped sheet.
Der in der DE-AZ-2 423 305 beschriebene und dargestellte Rost weist Längskanten auf, die zu einem geschlossenen Profil eingerollt sind. Zwischen den Längskanten sind Tragstege vorgesehen, von denen jeder von jedem benachbarten Tragsteg durch einen Einlaufschlitz getrennt ist. Jeder Einlaufschlitz weist einen Rand auf der parallel zu jedem Tragsteg in eine schräge Einlauffläche übergeht.The grate described and shown in DE-AZ-2 423 305 has longitudinal edges which are rolled into a closed profile. Support webs are provided between the longitudinal edges, each of which is separated from each adjacent support web by an inlet slot. Each inlet slot has an edge on which runs parallel to each support web into an inclined inlet surface.
Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen Rost aus Stahlblech für Entwässerungsrinnen so auszubilden, daß er auch erhöhten Belastungen standhält.The invention, as characterized in the claims, solves the problem of designing a grate from sheet steel for drainage channels so that it can withstand increased loads.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß der Rost nicht nur allen Belastungen, auch solchen der Gruppen B und C, standhält, sondern dabei leicht und trotzdem bruchfest ist. Der Rost nach der Erfindung ist in Querrichtung durch die Tragstege, in Längsrichtung durch die Seitenstege des Innenrosts zusätzlich stabilisiert. Bei der Erfindung ist vorgesehen, einem Außenrost bestimmter Blechstärke Innenroste unterschiedlicher Blechstärke zuzuordnen, um so die Tragfähigkeit den Belastungen anzupassen. Die Grenze in den Variationsmöglichkeiten besteht dabei lediglich in der Rückenbreite des Tragstegs des Innenrosts, der in den Tragsteg des Außenrosts gelegt wird. Mit den zwischen den abgewinkelten Längskanten des Außenrosts gehaltenen Seitenstegen des Innenrosts einerseits sowie mit den zwischen den schrägen Einlaufflächen der Tragstege des Außenrosts gehaltenen Tragstegen des Innenrosts andererseits ist eine stabile Verbindung geschaffen, die keine zusätzliche Befestigung mehr benötigt. Vielmehr ist der Innenrost unverrückbar in dem Außenrost gehalten. Der Innenrost behindert die Entwässerung nicht, da die Einlaufschlitze des Außenrosts vollständig offen bleiben. Auch die Säuberung des Rosts ist nicht behindert. Außen- und Innenrost können in bekannter Weise aus sendzimierverzinktem Stahlblech, aus Stahlblech, welches nach dem Verformen feuerverzinkt wird, oder aus Edelstahlblech hergestellt werden. Es ist vorteilhaft, dem Außenrost an der Oberfläche in üblicher Weise Stoppwarzen zum Gleitschutz einzuprägen.The advantages achieved by the invention are essentially to be seen in the fact that the grate not only withstands all loads, including those of groups B and C, but is light and nevertheless unbreakable. The grate according to the invention is additionally stabilized in the transverse direction by the support webs and in the longitudinal direction by the side webs of the inner grate. In the invention, it is provided to assign an outer grate of a certain sheet thickness to inner grates of different sheet thickness so as to adapt the load-bearing capacity to the loads. The limit in the possible variations is only the back width of the support bar of the inner grate, which is placed in the support bar of the outer grate. With the side webs of the inner grating held between the angled longitudinal edges of the outer grating on the one hand and with the supporting webs of the inner grating held between the oblique entry surfaces of the supporting webs of the outer grating on the other hand, a stable connection is created which no longer requires additional fastening. Rather, the inner grate is held immovably in the outer grate. The inner grate does not hinder the drainage, since the inlet slots of the outer grate remain completely open. The cleaning of the grate is also not hindered. The outer and inner grate can be produced in a known manner from sendzimier galvanized steel sheet, from steel sheet which is hot-dip galvanized after being deformed, or from stainless steel sheet. It is advantageous to stamp stop lugs on the surface in the usual way for anti-slip protection.
Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt

Der als Ausführungsbeispiel gewählte Rost für Entwässerungsrinnen besteht aus einem Außenrost 1 und einem in dem Außenrost befestigten Innenrost 2. Außenrost 1 und Innenrost 2 sind leiterartig ausgebildet und aus Stahlblech hergestellt.The grate for drainage channels chosen as an exemplary embodiment consists of an outer grate 1 and an
Der Außenrost 1 weist zwei Längskanten 11 auf, von denen jede aus einer hochgestellten Fläche 12 und einer zur gegenüberliegenden Längskante abgewinkelten Fläche 13 besteht. Zwischen den Längskanten 11 sind Tragstege 14 vorgesehen. Die Tragstege 14 sind mit nach außen vorspringenden Stoppnoppen 15 versehen. Zwischen benachbarten Tragstegen 14 ist jeweils ein Einlaufschlitz 16 vorgesehen. Jeder Einlaufschlitz 16 weist einen in Richtung der hochgestellten Fläche 12 gesickten und parallel zu jedem Tragsteg 14 in eine schräge Einlauffläche 17 übergehenden Rand 18 auf.The outer grate 1 has two
Der Innenrost 2 ist von zwei Seitenstegen 21 und von zwischen den Seitenstegen 21 angeformten Tragstegen 22 gebildet. Der Innenrost 2 ist mit seinen Seitenstegen 21 zwischen den abgewinkelten Längskanten 11 des Außenrosts 1 gehalten. Die Tragstege 22 des Innenrosts 2 liegen an den Tragstegen 14 des Außenrosts 1 an.The
Die Seitenstege 21 des Innenrosts 2 sind aus je einem hochgestellten Randstreifen eines der Stahlbleche gebildet. Die Tragstege 22 sind nach Art einer umgekehrten Rinne ausgebildet. Im Querschnitt entsteht im wesentlichen ein umgekehrtes U-Profil. Mit ihrem Rücken 23 liegen die Tragstege 22 des Innenrosts 2 innen an den Tragstegen 14 des Außenrosts 1 an. Mit den Stirnseiten 24 ihrer Seitenwände 25 stoßen die Tragstege 22 an die Seitenstege 21 an. Der Rücken 23 jedes Tragstegs 22 geht an den Stirnseiten in die Seitenstege 21 über.The
Da die Tragstege 22 des Innenrosts 2 aus demselben Stahlblech gefertigt sind wie die Seitenstege 21, kann bei vorgegebenem Abstand der Einlaufschlitze 16 des Außenrosts 1 möglicherweise - wie im Ausführungsbeispiel - nur jeweils an jedem zweiten Tragsteg 14 des Außenrosts 1 ein Tragsteg 22 des Innenrosts 2 anliegen. Werden bei dem Außenrost 1 die Einlaufschlitze 16 in größerem Abstand voneinander angeordnet oder ist die hochgestellte Fläche 12 kürzer ausgeführt, kann unter Beibehaltung des Prinzips, daß sowohl der Außenrost 1 als auch der Innenrost 2 jeweils aus einem Stahlblech hergestellt werden, trotzdem an jeden Tragsteg 14 des Außenrosts 1 ein Tragsteg 22 des Innenrosts 2 angelegt werden. Die Belastbarkeit des Rosts kann aber auch dadurch erhöht werden, daß für den Innenrost 2 ein stärkeres Stahlblech verwendet wird, wodurch sowohl die Seitenstege 21 als auch die Tragstege 22 dickere Seitenwände erhalten, was die Stabilität erhöht.Since the
Der Innenrost 2 ist in dem Außenrost 1 einmal mit seinen Seitenstegen 21 zwischen den abgewinkelten Längskanten 11 gehalten, zum anderen mit seinen Tragstegen 22 in Anlage an die Tragstege 14 zwischen den abgewinkelten Einlaufflächen 17. Der Innenrost 2 ist so unverrückbar in dem Außenrost 1 gehalten, ohne daß es einer zusätzlichen Befestigung bedarf.The
Die Herstellung des Rosts geschieht am einfachsten mit folgendem Verfahren : In ein für den Außenrost 1 vorgesehenes Stahlblech werden im ersten Arbeitsgang Mulden und die Stoppwarzen 15 eingepreßt. Getrennt davon werden gleichzeitig in ein für den Innenrost 2 vorgesehenes Stahlblech die Umrisse der Seitenstege 21 und der Tragstege 22 aus- und eingeschnitten. Im zweiten Arbeitsgang werden in dem für den Außenrost 1 vorgesehenen Stahlblech die Mulden aufgeschnitten sowie die Endstücke beschnitten. Getrennt davon werden gleichzeitig die Seitenwände 25 der Tragstege 22 des Innenrosts 2 hochgestellt. Im dritten Arbeitsgang werden die Einlaufflächen 16 an den Tragstegen 14 und die Längskanten 11 des Außenrosts 1 hochgestellt. Getrennt davon werden gleichzeitig die Seitenstege 21 des Innenrosts 2 hochgestellt. Sodann wird der Innenrost 2 in den Außenrost 1 eingelegt, sodaß die Tragstege 22 in den Tragstegen 14 liegen. Es werden dann die Längskanten 11 des Außenrosts 1 abgewinkelt und um die Seitenstege 21 des Innenrosts 2 gepreßt. Die vorgenannten Arbeitsgänge werden auf derselben Presse in einem Schrittwerkzeug durchgeführt.The easiest way to produce the grate is using the following method: in a steel sheet provided for the outer grate 1, depressions and the
