Abstract

The invention relates to a grid comprising support rods that are disposed parallel to each other, filling rods which interconnect the support rods and are arranged perpendicular thereto, and a border. The inventive grid is provided with higher support rods in some areas than in the other areas.

Description

BESCHREIBUNG Gitterrost DESCRIPTION Grating
Die Erfindung betrifft einen Gitterrost, bestehend aus parallel zueinander angeordneten Tragstäben und diese miteinander verbindenden, quer zu den Tragstäben angeordneten Füllstäben und einer Randeinfassung.The invention relates to a grid, consisting of mutually parallel support rods and connecting them, arranged transversely to the support rods Füllstäben and an edge enclosure.
Derartige Gitterroste sind bekannt, beispielsweise aus der DE 201 00 630 Ul, und werden als Bauelement in vielen Bereichen eingesetzt, insbesondere als Boden-, Brüstungs-, Treppenoder Fassadenelement.Such gratings are known, for example from DE 201 00 630 Ul, and are used as a component in many areas, in particular as a floor, parapet, stair or facade element.
In Abhängigkeit von der zu erwartenden Belastung wird der Gitterrost mehr oder weniger massiv ausgeführt. Die Abtragung von Lasten ist generell mit Tragstäben, bei denen das Verhältnis zwischen Höhe und Dicke groß ist (im Allgemeinen 20:1 und mehr) wesentlich wirtschaftlicher zu bewerkstelligen als mit Tragstäben, bei denen dieses Verhältnis kleiner ist.Depending on the expected load, the grate is made more or less massive. The removal of loads is generally much more economical to accomplish with support bars where the ratio between height and thickness is large (generally 20: 1 and more) than with support bars where this ratio is smaller.
Auch bei nur lokal auftretenden erhöhten Belastungen müssen gemäß dem Stand der Technik jeweils diesen erhöhten Belastungen angepaßte massivere Gitterroste verwendet werden, da nur Gitterroste mit jeweils gleichmäßig dimensionierten Trag- und Füllstäben erhältlich sind. Andererseits stellt sich das Problem, daß sich bei einer relativ geringen Anzahl hoch belastbarer Tragstäbe ein offenes Maschenbild des Gitterrostes ergibt, so daß kleinere Gegenstände durch den Gitterrost durchfallen können.Even with only locally occurring increased loads must be used according to the prior art each of these increased loads adapted solid gratings, since only gratings are each available with uniformly sized support and filler rods. On the other hand, there is the problem that results in a relatively small number of highly resilient support rods an open mesh pattern of the grid, so that smaller objects can fall through the grid.
Aufgabe der Erfindung ist es, einen Gitterrost zu schaffen, der ein optimales Verhältnis bezüglich der lokalen Belastbarkeit und den Kosten des Gitterrostes ermöglicht und der zudem ein relativ enges Maschenbild ermöglicht.The object of the invention is to provide a grating, which allows an optimal ratio with respect to the local load capacity and the cost of the grating and also allows a relatively narrow stitch pattern.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Gitterrost in Teilbereichen höhere Tragstäbe aufweist als in den übrigen Bereichen.This object is achieved in that the grating has subsections higher support rods than in the other areas.
Hierdurch wird erreicht, daß der Gitterrost in den Teilbereichen, die einer höheren Belastung ausgesetzt sind, dieser standhält, da die dort angeordneten höheren Tragstäbe verstärkend wirken. Mit der Höhe der Tragstäbe steigt deren Belastbarkeit im Quadrat, d.h. bei einer doppelten Höhe der Tragstäbe erhöht sich deren Belastbarkeit um das Vierfache. In den übrigen Bereichen, die einer geringeren Belastung ausgesetzt sind, bleibt der Materialeinsatz hingegen gleich und es kann mit Tragstäben geringerer Höhe kostengünstig ein enges Maschenbild erreicht werden. Das Verhältnis zwischen lokaler Belastbarkeit und den Kosten des Gitterrostes wird daher optimiert.This ensures that the grate in the sub-areas which are exposed to a higher load, this withstands, since the arranged there higher support rods act reinforcing. With the height of the support rods increases their capacity in the square, ie at a Double the height of the support bars increases their capacity by four times. In the other areas, which are exposed to a lower load, the use of materials, however, remains the same and it can be achieved cost-effectively with support bars lesser height a tight mesh image. The relationship between local load capacity and the cost of the grid is therefore optimized.
Eine bevorzugte Ausgestaltung der Erfindung besteht darin, daß der Gitterrost ein Preßrost ist.A preferred embodiment of the invention is that the grid is a grate.
Ein Ausfuhrungsbeispiel der Erfindung wird nachfolgend anhand von Zeichnungen beschrieben. An embodiment of the invention will be described below with reference to drawings.
Es zeigenShow it
Fig. 1 einen erfindungsgemäßen GitterrostFig. 1 a grate according to the invention
undand
Fig. 2 eine Teilansicht dieses Gitterrostes.Fig. 2 is a partial view of this grid.
Wie aus Fig. 1 ersichtlich, besteht der erfmdungsgemäße Gitterrost, bei dem es sich um einen Preßrost handelt, aus Tragstäben 1, quer zu diesen Tragstäben 1 angeordneten Füllstäben 2 sowie einer Randeinfassung 3.As can be seen from FIG. 1, the grate according to the invention, which is a press grate, consists of support rods 1, filler rods 2 arranged transversely to these support rods 1 and an edge enclosure 3.
In Fig. 2 ist dargestellt, daß in dem Bereich X die Tragstäbe Ib eine größere Höhe h2 aufweisen als die Tragstäbe Ia in den übrigen Bereichen, deren Höhe als Ji1 bezeichnet ist. Da die Höhe der Tragstäbe 1 im Quadrat in die Berechnung der Belastbarkeit eingeht, ist die Belastbarkeit des Gitterrostes im Bereich X bei Tragstäben Ib, die doppelt so hoch sind wie die Tragstäbe Ia um das Vierfache höher als in den übrigen Bereichen. Somit kann mit geringstmöglichen Kosten eine maximale lokale Belastbarkeit des Gitterrostes erreicht werden. Die Tragstäbe Ib größerer Höhe dienen somit im wesentlichen dem Abfangen der Belastungen, die Tragstäbe Ia geringerer Höhe dem Erreichen eines engen Maschenbildes mit geringen Materialkosten.In Fig. 2 it is shown that in the region X, the support rods Ib have a greater height h 2 than the support rods Ia in the remaining areas, whose height is referred to as Ji 1 . Since the height of the support bars 1 in square is included in the calculation of the load capacity, the load capacity of the grating in the area X in support bars Ib, which are twice as high as the support bars Ia by four times higher than in the other areas. Thus, a maximum local load capacity of the grid can be achieved with the lowest possible cost. The support bars Ib larger height thus serve essentially the interception of the loads, the support bars Ia lesser height to achieve a narrow mesh image with low material costs.
Selbstverständlich sind auch beliebige andere Höhenverhältnisse h2 : h] möglich.Of course, any other height ratios h 2 : h] are possible.
Es liegt auch im Rahmen der Erfindung, daß nur ein einzelner Tragstab 1 eine größere Höhe h2 aufweist als die übrigen Tragstäbe 1. It is also within the scope of the invention that only a single support bar 1 has a greater height h 2 than the other support bars. 1
