Abstract

In the metal grid with its grid body ending, at two opposite ends, in mounting rails (12) which are angled off from the plane of the grid, and fabricated from a single sheet metal blank, the grid webs (15) are interconnected in the surface plane of the grid body by means of bars (19, 20) which extend transversely to the grid webs. Said bars can be easily attached, afford adequate transverse stabilisation of the grid webs, permit strong lateral light penetration and can at the same time afford protection against slipping. <IMAGE>

Description

Die Erfindung betrifft ein Metallrostelement mit den im Oberbegriff des Hauptanspruches aufgeführten Merkmalen.The invention relates to a metal grate element with the features listed in the preamble of the main claim.

Ein Metallrostelement mit solchen Merkmalen ist aus der DE-A-20 11 020 bekannt, eignet sich jedoch nicht zur Bildung begehbarer Flächen, weil dort die einzelnen Roststege keine stabilen Verbindungselemente zwischen den Montageschienen bilden und bei Wechselbelastungen, wie sie beim Begehen auftreten, in der Rostebene ins Schwingen kommen können. Ein weiterer Nachteil besteht darin, daß das bekannte Metallrostelement breite Randstege mit benachbarten Querrinnen aufweist, welche lichtdurchlässige Flächen des Gitterrostes merklich vermindern. Die bekannten Metallrostelemente erlauben also keine Bildung einer Rostfläche mit durchgehend gleicher Rostebene.A metal grate element with such features is known from DE-A-20 11 020, but is not suitable for the formation of walkable areas, because there the individual grate webs do not form stable connecting elements between the mounting rails and in the event of alternating loads such as occur when walking on Rust level can start to vibrate. Another disadvantage is that the known metal grate element has wide edge webs with adjacent transverse channels, which noticeably reduce translucent surfaces of the grating. The known metal grate elements therefore do not allow the formation of a grate surface with the same grate level throughout.

Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung der vorstehend genannten Nachteile ein Metallrostelement der vorstehend genannten Art so auszubilden, daß sich mit solchen Elementen stabile begehbare Rostflächen mit einem hohen Luft- und Lichtdurchlässigkeitsgrad zusammensetzen lassen.The invention is based on the object, avoiding the disadvantages mentioned above, to design a metal grate element of the aforementioned type such that stable walkable grate surfaces with a high degree of air and light transmission can be assembled with such elements.

Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Hauptanspruches aufgeführten Merkmale gelöst.The object is achieved according to the invention by the features listed in the characterizing part of the main claim.

Zwar zeigt die GB-A-20 28 389 bereits ein Gitterelement, bei welchem die Roststege durch mit Abstand voneinander quer verlaufende Stäbe miteinander verbunden sind. Es handelt sich dort aber um einen Gitterrost, der nicht aus einem einzigen Blechzuschnitt gebildet, sondern aus einzelnen Bandstreifen zusammengesetzt ist.GB-A-20 28 389 already shows a lattice element in which the grate webs are connected to one another by bars which extend transversely from one another. However, it is a grating that is not formed from a single sheet metal blank, but is composed of individual strip strips.

Ein Metallrostelement gemäß der Erfindung bildet im Verband mit mehreren Elementen eine durchgehend ebene Rostfläche. Dies läßt sich erfindungsgemäß dadurch erreichen, daß im Blechzuschnitt die noch nicht aus der Zuschnittebene ausgebogenen Roststege durch mindestens über den Hauptteil der Breite der Rostebene parallel zueinander verlaufende Schnittlinien begrenzt sind, die an beiden Enden schräg abgewinkelte Endabschnitte aufweisen, die in Stanzlöchern enden, die jeweils auf einem Breitenwert des Blechzuschnittes liegen, welcher die Mitte zwischen zwei benachbarten Schnittlinien bildet.A metal grate element according to the invention forms a continuous flat grate surface in association with several elements. This can be achieved according to the invention in that the grate webs which have not yet been bent out of the cutting plane are delimited by cut lines which run parallel to one another at least over the main part of the width of the grate plane and which have obliquely angled end sections at both ends, each of which ends in punched holes lie on a width value of the sheet metal blank, which forms the middle between two adjacent cutting lines.

Außerdem läßt sich die durchgehend ebene Rostfläche dadurch sichern, daß in beiden Montageschienen des Metallrostelementes miteinander fluchtende Montagelöcher ausgebildet sind, deren Ränder nach der gleichen Seite konisch eingepreßt sind, so daß die Montagelächer der einen Montageschiene nach innen und die dazu fluchtenden Montagelöcher der anderen Montageschiene nach außen aus der Montageschienenebene versetzt sind. Bei dieser Ausbildung der Metallrostelemente können die Ränder von nach außen versetzten Montagelöchern eines Metallrostelementes in die nach innen versetzten Ränder der Montagelöcher eines benachbarten Metallrostelementes eintauchen und in dieser Formschlußverbindung mittels Durchgangsschrauben miteinander verbunden werden.In addition, the continuously flat grate surface can be secured in that mounting holes that are flush with one another are formed in both mounting rails of the metal grate element, the edges of which are pressed in conically on the same side, so that the mounting holes of one mounting rail toward the inside and the mounting holes aligned therewith follow the other mounting rail are offset from the outside of the mounting rail level. With this design of the metal grate elements, the edges of outwardly offset mounting holes of a metal grate element can dip into the inwardly set edges of the mounting holes of an adjacent metal grate element and can be connected to one another in this form-fit connection by means of through-bolts.

Durch die Anordnung der querstabilisierenden Roststege in der Rostebene wird durch die Stäbe die Luft- und Lichtdurchlässigkeit der Rostelemente nur unwesentlich beeinflußt. Sie erlauben einen starken Seitenlichteinfall und lassen sich mit kostengünstigen Verfahren anbringen. Beispielsweise können sie auf das Rostelement aufgelegt und im elektrischen Widerstandsschweißverfahren durch Schweißpressung mit den Roststegen fest verbunden werden. Dabei können die zweckmäßig mit einer gerippten oder kantigen Oberfläche versehenen Stäbe so befestigt werden, daß sie teilweise über den die Rostebene bildenden oberen Rand der Roststege überstehen und gleichzeitig eine Rutschgefahr vermindernde Vorsprünge bilden. Es können aber auch die Roststege zur Beseitigung einer Rutschgefahr auf der Rostebene an ihrem oberen Rand stumpfwinkelige Vorsprünge aufweisen.Due to the arrangement of the cross-stabilizing grate webs in the grate plane, the air and light permeability of the grate elements are only slightly influenced by the bars. They allow strong incidence of sidelights and can be attached using cost-effective methods. For example, they can be placed on the grate element and firmly connected to the grate bars in the electrical resistance welding process by welding pressure. The rods, which are expediently provided with a ribbed or angular surface, can be fastened in such a way that they partially protrude beyond the upper edge of the grating webs forming the grating plane and at the same time form projections which reduce the risk of slipping. However, the grate webs can also have obtuse-angled projections on their upper edge to eliminate the risk of slipping on the grate plane.

Nachfolgend werden zwei Ausführungsbeispiele eines Metallrostelementes gemäß der Erfindung anhand der beiliegenden Zeichnung näher erläutert.Two exemplary embodiments of a metal grate element according to the invention are explained in more detail below with reference to the accompanying drawing.

In den Figuren sind bei beiden Ausführungsbeispielen gleiche Teile mit den gleichen Bezugsziffern bezeichnet. Beide Metallrostelemente 10 und 10' sind aus einem einzigen und in Fig. 5 bereits mit den Stanzschnitten und Stanzausnehmungen dargestellten Metallblechzuschnitt 11 gefertigt. Die eine Rechteckform aufweisenden Metallrostelemente 10 und 10′ weisen entlang beider Längsränder aus der Rostebene E senkrecht abgewinkelte Montageschienen 12 und 13 auf, die aus den beiden Randbereichen 12.1 und 13.1 des in Fig. 5 dargestellten Blechzuschnittes 11 geformt sind und in einem abgewinkelten freien Rand 14 enden. Die Breite der Montageschienen 12 kann entsprechend dem Verwendungszweck des Metallrostelementes unterschiedlich sein, was in den Fig. 2 und 4 durch eine unterschiedliche Lage der abgekanteten freien Ränder 14 mit gestrichelten Linien angedeutet ist. Zwischen den beiden Montageschienen 12 und 13 erstrecken sich in gleichmäßigen Abständen von beispielsweise 15 mm Roststege 15. Sie bestehen aus von Stanzschnitträndern 16 gebildeten Streifen 15.1 des Metallblechzuschnittes 11, die durch Verschränken senkrecht zur Ausgangsebene des Blechzuschnittes 11 gestellt sind und mit ihrem oberen Rand 17 die Rostebene E bilden.In the figures, the same parts are designated by the same reference numerals in both exemplary embodiments. Both metal grate elements 10 and 10 'are from a single and in Fig. 5 already with the die cuts and Stamped recesses shown sheet metal blank 11 made. The rectangular grate metal grate elements 10 and 10 'have along both longitudinal edges from the grate plane E vertically angled mounting rails 12 and 13, which are formed from the two edge regions 12.1 and 13.1 of the sheet metal blank 11 shown in Fig. 5 and in an angled free edge 14th end up. The width of the mounting rails 12 can vary depending on the intended use of the metal grate element, which is indicated in FIGS. 2 and 4 by a different position of the bent free edges 14 with dashed lines. Between the two mounting rails 12 and 13 extend at regular intervals of, for example, 15 mm grate bars 15. They consist of strips 15.1 of the sheet metal blank 11 formed by punched cut edges 16, which are set perpendicularly to the starting plane of the sheet metal blank 11 and with their upper edge 17 Form grate level E.

Wie aus Fig. 5 ersichtlich ist, weisen alle Stanzschnittlinien 16 schräg abgewinkelte Endabschnitte 16.1 auf und enden in Stanzlöchern 18, die etwa in der Mitte zwischen zwei Stanzschnittlinien 16 liegen. Durch diese Ausbildung lassen sich Roststege gemäß Fig. 2 und 4 so aus der Ausgangsebene des Blechzuschnittes 11 verschränken, daß der obere Rand der Roststege 15 eben in die oberen Ränder 12.2 und 13.2 der Montageschienen 12 und 13 auslaufen.As can be seen from FIG. 5, all punch cut lines 16 have obliquely angled end sections 16. 1 and end in punch holes 18 which lie approximately in the middle between two punch cut lines 16. 2 and 4 can be entangled from the starting plane of the sheet metal blank 11 in such a way that the upper edge of the grating webs 15 ends in the upper edges 12.2 and 13.2 of the mounting rails 12 and 13.

Die mit Abstand parallel zueinander verlaufenden Roststege 15 sind durch quer zu ihnen und parallel zu den Montageschienen 12 und 13 verlaufende Stäbe 19 oder 20 miteinander zu einem starren Verband verbunden. Beim Ausführungsbeispiel nach den Fig. 1 und 2 sind gerippte Stäbe 19 verwendet, die durch Preßschweißen mit den Roststegen so verbunden sind, daß sie gemäß Fig. 2 zur Hälfte mit ihrer gerippten Oberfläche über den oberen Rand 17 der Roststege 15 vorstehen und dadurch gleichzeitig Vorsprünge zur Beseitigung einer Rutschgefahr bilden. Bei dem Ausführungsbeispiel nach den Fig. 3 und 4 sind glatte Stäbe 20 vorgesehen, die in vorgestanzte Randausnehmungen 21 der Roststege 15 eingelegt und durch Verpressen fest mit den Roststegen 15 verbunden sind. In Fig. 5 sind die Stanzlöcher 21.1 angedeutet, welche die Randausnehmungen 21 in den Roststegen 15 bilden. Bei dieser Form der Anordnung der Stäbe 20 ist der obere Rand 17 der Roststege 15 mit stumpfwinkeligen Vorsprüngen 22 versehen, welche Sicherheitsvorsprünge zu Vermeidung einer Rutschgefahr bilden. Ein zur Bildung dieser Sicherheitsvorsprünge 22 führender abgewinkelter Verlauf der Stanzschnittlinien 16 ist in Fig. 5 an einer Stelle 22.1 mit gestrichelter Linie angedeutet.The grating webs 15, which run parallel to one another at a distance, are by bars 19 or 20 running transversely to them and parallel to the mounting rails 12 and 13 joined together to form a rigid bandage. In the embodiment according to FIGS. 1 and 2, ribbed bars 19 are used, which are connected by pressure welding to the grate bars so that, according to FIG form to eliminate a risk of slipping. In the embodiment according to FIGS. 3 and 4, smooth rods 20 are provided, which are inserted into pre-punched edge recesses 21 of the grate bars 15 and are firmly connected to the grate bars 15 by pressing. 5, the punched holes 21.1 are indicated, which form the edge recesses 21 in the grate webs 15. In this form of arrangement of the bars 20, the upper edge 17 of the grate webs 15 is provided with obtuse-angled projections 22, which form safety projections to avoid a risk of slipping. An angled course of the punching cut lines 16 leading to the formation of these safety projections 22 is indicated in FIG. 5 at a point 22.1 with a dashed line.

In beiden Montageschienen 12 und 13 sind in der Nähe der Rostebene E Montagelöcher 23 und 24 ausgebildet. Durch ein konisches Einpressen der Öffnungsränder 23.1 und 24.1 sind die Montagelöcher 23 und 24 beide aus der Ebene der Montageschienen 12 oder 13 versetzt, und zwar die Montagelöcher 23 aus der Montageschiene 12 nach innen und die Montagelöcher 24 aus der Montageschiene 13 nach außen. Bei parallel aneinandergefügten Metallrostelementen 10 oder 10′ ragen die nach außen vorstehenden Öffnungsränder 24.1 in die nach innen vorstehenden Öffnungsränder 23.1 von miteinander fluchtenden Montagelöchern 23 und 24. Die Montageschienen 12 und 13 können weitere und nicht aus ihrer Ebene versetzte Montageöffnungen 25 aufweisen.Mounting holes 23 and 24 are formed in both mounting rails 12 and 13 near the grate level E. By conically pressing the opening edges 23.1 and 24.1, the mounting holes 23 and 24 are both offset from the plane of the mounting rails 12 or 13, namely the mounting holes 23 from the mounting rail 12 inwards and the mounting holes 24 from the mounting rail 13 to the outside. When parallel metal grate elements 10 or 10 'protrude the outwardly projecting opening edges 24.1 in the inwardly projecting opening edges 23.1 of mutually aligned mounting holes 23 and 24. Die Mounting rails 12 and 13 can have further mounting openings 25 which are not offset from their plane.

Die Stäbe 19 und 20 müssen keine Stäbe mit rundem Querschnitt sein. Sie könnten beispielsweise auch einen eckigen Querschnitt aufweisen, wobei ihre Kanten auch durch Verdrehen der Stäbe schraubenlinienförmig verlaufen können.The bars 19 and 20 need not be bars with a round cross-section. For example, they could also have an angular cross section, and their edges can also run in a helical shape by rotating the rods.
