The slots (7) are formed by an arrangement (3,4,5) comprising a cut-out or stamped section in the carrier slats. The arrangement is pressed in the carrier slat plane, once the lateral slat (2) has been located.

Description

Die Erfindung betrifft einen Gitterrost aus Metall mit Tragstäben etwa rechteckiger Grundform und die Tragstäbe verbindende Querstäbe, wobei die Tragstäbe zu den Querstäben rechtwinklig verlaufend ausgerichtet und hochkant angeordnet sind, und daß die Tragstäbe in ihren Flanken Durchtrittsspalte zum Durchstecken der entsprechend profilierten Querstäbe aufweisen.The invention relates to a grating made of metal with supporting rods, for example rectangular basic shape and cross bars connecting the supporting bars, wherein the support rods are aligned at right angles to the cross rods and arranged upright, and that the support rods in their Flanking passage gaps for pushing through the correspondingly profiled ones Have cross bars.

Ein Gitterrost mit diesen Merkmalen ist bekannt (DE 33 44 351 A), bei dem die Tragstäbe in ihren Flanken Lochungen zum Durchstecken der entsprechend profilierten Querstäbe aufweisen, die in ihrem zwischen den Tragstäben befindlichen Bereich, mindestens in unmittelbarer Nähe zum Tragstab so verformt sind, daß das Verbindungsmaterial oberhalb und unterhalb der Lochungen gegen die Wange des Tragstabes angelegt ist.A grating with these features is known (DE 33 44 351 A), in which the support rods in their flanks perforations for pushing through accordingly have profiled crossbars in their between the Area located at least in the immediate vicinity of the Support rod are deformed so that the connecting material above and below the perforations against the cheek of the support rod.

Eine derartige Konstruktion ist insbesondere für einen Gitterrost aus Aluminium gedacht, da ein solches Verpressen nur bei weichen Werkstoffen rationell durchgeführt werden kann. Bei härteren Werkstoffen müssen in diesen Bereichen Röhrchen an den Querstäben eingesetzt werden, die teuer sind und deren Verfügbarkeit bei Sonderwerkstoffen sehr begrenzt ist. Insbesondere ergibt sich bei dieser Ausführungsform ein hoher Aufwand für die Herstellung des Gitterrostes durch die hohen Werkzeugkosten. Ein weiterer wesentlicher Nachteil besteht darin, daß die Roste als fortlaufendes Band produziert und dann in die entsprechende Form geschnitten werden und hierbei ein hoher Abfall produziert wird.Such a construction is particularly suitable for a grating Aluminum thought, because such pressing only with soft materials can be carried out efficiently. For harder materials must have tubes on the cross bars in these areas that are expensive and their availability for special materials is very limited. This results in particular in this embodiment high effort for the production of the grating due to the high Tooling costs. Another major disadvantage is that the gratings are produced as a continuous belt and then into the corresponding one Cut shape and produces a high waste becomes.

Der Erfindung liegt die Aufgabe zugrunde, einen derartigen Gitterrost so auszubilden, daß er von der Fertigungsmöglichkeit her an kein Raster und damit auch an keine vorgegebenen Abmessungen gebunden ist. The invention has for its object such a grate train that there is no grid from the production possibility and therefore not tied to any given dimensions.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Durchtrittsspalte durch in den Tragstäben eingeschnittene und geprägte Laschen gebildet sind und daß die Laschen nach dem Einstecken der Querstäbe in der Tragstabebene verpreßt sind.This object is achieved according to the invention in that the passage gaps through cut and embossed in the support rods Tabs are formed and that the tabs after inserting the Cross bars are pressed in the support bar level.

Eine vorteilhafte Ausführungsform besteht darin, daß die Durchtrittsspalte durch den Abstand der der Biegekante der Lasche gegenüberliegenden Vorderkante und der Vorderkante des Einschnittes gebildet sind.An advantageous embodiment is that the passage gaps by the distance of the opposite of the bending edge of the tab The leading edge and the leading edge of the incision are formed.

Weiterhin ist es vorteilhaft, daß die Lasche S-förmig geprägt ist.It is also advantageous that the tab is S-shaped.

Es wird weiterhin vorgeschlagen, daß die Lasche parallel zur Tragstabebene herausgeformt ist.It is also proposed that the tab be parallel to the support rod level is molded out.

Schließlich ist es vorteilhaft, daß die Lasche in einem spitzen Winkel zur Tragstabebene herausgeformt ist.Finally, it is advantageous that the tab at an acute angle to Support rod level is formed.

Der erfindungsgemäße Gitterrost kann aus den verschiedensten Metallen, wie Aluminium, Stahl, Edelstahl, Sonderwerkstoffen, wie Titan, Tantal oder Zirkonium bestehen, wobei sein Einsatz insbesondere bei Stoffaustauschkolonnen als Tragkonstruktion für Füllkörper und Packungskolonnen oder als begehbarer Rost bei Industrieanlagen wie Arbeitsbühnen, Bohrinseln oder dergleichen vorgesehen ist. Eine weitere Verwendungsmöglichkeit besteht bei Elektrofiltern, wobei der Gitterrost als elektrische Pol die Verunreinigungen aufnimmt. Dafür kann ein geringes Gewicht und eine stark vergrößerte Oberfläche erreicht werden. Es ist auch ein Einsatz im Bereich der Glühöfen als Halterung und Transportgestell möglich. Für die Herstellung werden keine Sonderwerkzeuge gebraucht und die Festigkeit des Gitterrostes kann jeweils an die geforderte Tragfähigkeit angepaßt werden. Die Herstellung der Stäbe und ihre Abmessungen können mit Rechnerprogrammen zusammengestellt werden, so daß bei jeder Kontur, ob eckig oder kreisförmig, mit oder ohne Ausschnitte kein Verschnitt gegeben ist. Ein entsprechendes Sägen oder Schneiden des Gitterrostes kann damit entfallen. Dies ist insbesondere bei teuren Werkstoffen von besonderer Bedeutung. Ein weiterer wesentlicher Vorteil besteht darin, daß wie bei anderen bekannten Konstruktionen keinerlei Schweißarbeiten mit allen Nacharbeitungen, wie Beizen und Passivieren bei Edelstählen und Sonderwerkstoffen, auch eine Abschirmung mit Schutzgas bei Sonderwerkstoffen, wie z.B. Titan, nicht erforderlich ist. Nachdem die Teile des Gitterrostes aus Blech herstellbar sind, ist eine große Verfügbarkeit des Vormaterials in allen Werkstoffen gegeben.The grating according to the invention can be made from a wide variety of metals, such as aluminum, steel, stainless steel, special materials such as titanium, tantalum or zirconium, its use especially in mass transfer columns as a supporting structure for packing and packing columns or as a walk-on grate in industrial plants such as work platforms, Oil rigs or the like is provided. Another possible use exists in the case of electrostatic filters, the grating being electrical Pol absorbs the impurities. This can be a lightweight and a greatly enlarged surface can be achieved. It is also a Use in the area of the annealing furnaces as holder and transport frame. No special tools are needed for the production and the strength of the grating can depend on the required load capacity be adjusted. The manufacture of the bars and their dimensions can be compiled with computer programs, so that at any contour, whether angular or circular, with or without cutouts none Waste is given. Appropriate sawing or cutting the Grating can thus be omitted. This is particularly the case with expensive materials really important. Another major advantage is that, as with other known constructions, none Welding work with all reworking, such as pickling and passivation for stainless steels and special materials, also with a shield Shielding gas for special materials, e.g. Titanium, is not required. After the parts of the grating can be made from sheet metal, one is great availability of the primary material in all materials.

Die Erfindung wird in der nachfolgenden Beschreibung anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert.The invention is described in the following description with reference to in the exemplary embodiments illustrated in the drawings.

Der in Fig. 1 dargestellte Gitterrost besteht aus einzelnen parallel verlaufenden, hochkant angeordneten Tragstäben 1, die mit Hilfe von vertikal dazu angeordneten Querstäben 2 verbunden sind, wobei die Höhe der Tragstäbe 1 entsprechend der Belastung festgelegt ist. Die Oberkante 11 dieser Tragstäbe 1 kann gezackt oder profiliert sein, wenn eine rutschsichere Ausführung erforderlich ist.The grating shown in Fig. 1 consists of individual parallel, upright arranged support rods 1, which with the help of vertically arranged cross bars 2 are connected, the Height of the support rods 1 is determined according to the load. The Top edge 11 of these support rods 1 can be serrated or profiled if a non-slip design is required.

Abweichend von der Darstellung in Fig. 1 können die Tragstäbe 1 bogenförmig als Ringsegmente verlaufen. Die Querstäbe 2 sind dann parallel zueinander angeordnet und radial zu den Tragstäben 1 oder senkrecht zur Auflagefläche ausgerichtet. Deviating from the illustration in Fig. 1, the support rods 1 can be arcuate run as ring segments. The cross bars 2 are then arranged parallel to each other and radially to the support rods 1 or aligned perpendicular to the contact surface.

Die Anordnung der Querstäbe 2 kann in beliebigen Abständen erfolgen und ihre Position von senkrecht, wie bei dem gezeigten Ausführungsbeispiel, bis waagerecht. Bei sehr hohen Tragstäben 1 können solche Querstäbe 2 in verschiedenen Höhen, d.h. oben und unten angeordnet sein. Weiterhin können die Querstäbe 2 an der Oberkante 11 der Tragstäbe bündig verlaufen oder etwas tiefer gesetzt sein.The arrangement of the cross bars 2 can take place at any intervals and their position from vertical, as in the embodiment shown, up to horizontal. With very high supporting bars 1, such cross bars can 2 at different heights, i.e. be arranged above and below. Furthermore, the cross bars 2 on the upper edge 11 of the support bars run flush or be set a little lower.

Für die Verbindung der Tragstäbe 1 mit den Querstäben 2 sind in den Tragstäben 1 Laschen 3 eingeschnitten und geprägt, wobei sich der Einschnitt 6 an einer Vorderkante und zwei senkrecht dazu verlaufenden Kanten 12 verläuft, wobei die der Vorderkante 9 gegenüberliegende hintere Kante 8 als Biegekante dient. Die Lasche wird dann derart geprägt, daß sie aus der Ebene des Tragstabes herausragt und sich hierbei zwischen der Vorderkante 9 der Lasche und der Vorderkante 10 des Einschnittes 6 ein Durchtrittsspalt 7 ergibt, dessen Breite A ausreichend ist, um die Querstäbe 2 hindurchzustecken.For the connection of the support rods 1 with the cross bars 2 are in the Carrier rods 1 cut 3 tabs and embossed, the Notch 6 on a front edge and two perpendicular to it Edges 12 runs, the one opposite the front edge 9 rear edge 8 serves as a bending edge. The tab is then embossed in such a way that it protrudes from the plane of the support rod and this between the front edge 9 of the tab and the front edge 10 of the Incision 6 gives a passage gap 7, whose width A is sufficient is to put the cross bars 2 through.

Die Figuren 2 bis 4 zeigen verschiedene Ausgestaltungen für das Prägen der Laschen, wobei in Fig. 2 eine S-förmig geprägte Lasche 3 vorgesehen ist, in Fig. 3 eine Lasche 4, die parallel zur Tragstabebene herausgeformt ist und Fig. 4 eine Lasche 5, die in einem spitzen Winkel zur Tragstabebene verläuft. Die Länge B der Lasche 3, 4, 5 wird entsprechend einer praktikablen Prägung durchgeführt und die Höhe C entsprechend der Höhe der Querstäbe 2.Figures 2 to 4 show different configurations for embossing of the tabs, an S-shaped tab 3 being provided in FIG. 2 is, in Fig. 3, a tab 4, which is formed parallel to the support rod plane and Fig. 4 is a tab 5 which is at an acute angle to the support rod plane runs. The length B of the tab 3, 4, 5 becomes corresponding carried out a practical embossing and the height C accordingly the height of the cross bars 2.

Der Gitterrost läßt sich mit solchen Tragstäben 1 und Querstäben 2 auf einfachste Art und Weise herstellen, indem zunächst die Laschen 3, 4, 5 eingeschnitten und geprägt werden, anschließend die Querstäbe 2 eingelegt und dann die Laschen 3, 4, 5 verpreßt werden, wobei durch die Verformungsarbeit ein Kaltschweißen erfolgt. Die Randeinfassung kann dann mit beliebigen Profilen vorgenommen werden.The grating can with such support rods 1 and 2 crossbars Easiest way to produce, by first the tabs 3, 4, 5 cut and embossed, then the cross bars 2 inserted and then the tabs 3, 4, 5 are pressed, whereby by the deformation work is carried out by cold welding. The edging can then be made with any profile.
