 <Desc/Clms Page number 2> 

 durch rostbildende Querverbinder--2 bzw.   2'--über Schweissstellen--3--mitsammen   verbunden sind. 



   Im linken Teil der Fig. 1 ist eine besonders bevorzugte Ausführungsform des Erfindungsgegenstandes dargestellt, derzufolge alle Querverbinder--2--gemeinsam von einem über die Länge des Rostes durchlaufenden im Bereich jeder Anschlussstelle bogenförmig um 180  gekrümmten Stab gebildet werden ; die   Anschluss-und   Verbindungsstellen befinden sich dabei im Bogenscheitel, im Bereich zwischen den Bögen verlaufen die Stäbe   (Querverbinder--2--)   parallel zueinander. 



   Ähnlich ist die im rechten Teil der Fig. 1 dargestellte Ausführungsform. Hier ist der die   Querverbinder --2'-- bildende   Stab im Bereich jeder Anschlussstelle zweifach, also wieder um 1800 abgewinkelt, um mit einem zum   Randstab--l--parallelverlaufenden   Bereich an diesem Randstab anzuliegen und mit diesem verbunden zu sein. Diese Anordnung trägt insbesondere zur Verstärkung der   Randstäbe--l--bei.   



   Selbstverständlich müssen im Rahmen der Erfindung die Querverbinder nicht unbedingt aus einem durchlaufenden Einzelstab gebildet werden. Die Fig. 2 zeigt eine Vielzahl gerader Stäbe als Querverbinder--2--, die schrägverlaufend in   Zick-Zack-Anordnung   zwischen den beiden Randstäben angeordnet und endseitig (jeweils zwei benachbarte   Stäbe --2-- gemeinsam)   über die   Schweiss stellen --3-- mit   den   Randstäben-l-verbunden   sind. 



   PATENTANSPRÜCHE : 
1. Gitterrost, insbesondere für Schacht-und Kanalabdeckungen, bestehend aus geraden Längsstäben und einer Vielzahl diese Längsstäbe miteinander verbindender Querverbinder, wobei vorzugsweise sowohl die Längsstäbe als auch die Querverbinder aus hochkantstehendem, gleich hohem

  Grating, especially for manhole and sewer covers
 EMI1.1
 

 <Desc / Clms Page number 2>

 by means of rust-forming cross connectors - 2 or 2 '- via welds - 3 - are connected together.



   In the left part of FIG. 1, a particularly preferred embodiment of the subject matter of the invention is shown, according to which all transverse connectors - 2 - are formed together by a rod that runs through the length of the grate in the area of each connection point and is curved by 180 in an arc; the connection and connection points are located in the apex of the arch, in the area between the arches the bars (cross connectors - 2--) run parallel to one another.



   The embodiment shown in the right part of FIG. 1 is similar. Here, the rod forming the cross connectors - 2 '- is doubled in the area of each connection point, i.e. again angled by 1800, in order to rest against this edge rod with an area running parallel to the edge rod - 1 - and be connected to it. This arrangement contributes in particular to the reinforcement of the edge bars - l -.



   Of course, within the scope of the invention, the cross connectors do not necessarily have to be formed from a single continuous rod. Fig. 2 shows a large number of straight bars as cross connectors - 2 - which are arranged obliquely in a zigzag arrangement between the two edge bars and at the end (two adjacent bars - 2 together) over the weld - 3-- are connected to the edge bars-l-.



   PATENT CLAIMS:
1. Grating, in particular for manhole and sewer covers, consisting of straight longitudinal bars and a large number of transverse connectors connecting these longitudinal bars to one another, preferably both the longitudinal bars and the transverse connectors from edgewise, equally high
