Abstract

The present invention relates to a carrying structure, comprising a grating floor (2), supported on two support carriers (1), wherein the grating floor comprises flat carrying rods (3) and flat filler rods (4), wherein the carrying rods run parallel to the support carriers.

Description

Die folgende Erfindung betrifft eine Tragstruktur mit einem Gitterrostboden, der auf zwei Auflageträgern aufliegt, wobei der Gitterrostboden ebene Tragstäbe und ebene Füllstäbe aufweist. AT- 8461U offenbart eine derartige Tragstruktur.The following invention relates to a support structure with a grate floor, which rests on two support beams, wherein the grate floor has flat support rods and flat filler rods. AT-8461U discloses such a support structure.

Bei dieser gattungsgemäßen Tragstruktur werden die Tragstäbe beispielsweise mit Auflagewinkeln verschweißt, die dann wiederrum auf den Auflageträgern aufliegen. Diese Tragstruktur ist zum einen vergleichsweise aufwendig in der Herstellung und zum anderen bezüglich des Materialeinsatzes nicht optimiert.In this generic support structure, the support rods are welded, for example, with support brackets, which in turn rest on the support carriers. This support structure is for a comparatively expensive to manufacture and not optimized with respect to the other material use.

Es war deshalb die Aufgabe der vorliegenden Erfindung eine einfach herzustellende Tragstruktur zur Verfügung zu stellen, bei der bei gleicher Lastaufnahme ein geringerer Materialeinsatz erforderlich ist.It was therefore the object of the present invention to provide a support structure which is simple to produce and in which, with the same load bearing, a lesser use of material is required.

Gelöst wird die Aufgabe mit einer Tragstruktur mit zwei Auflagerträgern und einem Gitterrostboden, der auf den zwei Auflageträgern an- oder aufliegt, wobei der Gitterrostboden ebene Tragstäbe und ebene Füllstäbe aufweist, wobei die Tragstäbe parallel zu den Auflageträgern verlaufen und wobei der Gitterrostboden eine Umrandung aufweist und jeweils mindestens ein Tragstab collständig auf dem jeweiligen Auflageträger aufliegt.The problem is solved with a support structure with two support beams and a grate floor, the rests on the two support supports or rests, wherein the grate floor level support rods and flat filler rods, wherein the support rods are parallel to the support beams and wherein the grate floor has a border and each at least one support rod rests collley on the respective support carrier.

Die erfindungsgemäße Tragstruktur ist einfach und kostengünstig herzustellen. Trotz eines geringeren Materialeinsatzes können dieselben Lasten wie bei Tragstrukturen gemäß dem Stand der Technik aufgenommen werden.The support structure according to the invention is simple and inexpensive to manufacture. Despite lower material usage, the same loads as in prior art support structures can be accommodated.

Erfindungsgemäß weist die Tragstruktur zwei Auflageträger auf, die voneinander beabstandet sind. Auf diesen Auflageträgern liegt ein Gitterrostboden an oder auf, der aus ebenen Tragstäben und ebenen Füllstäben gefertigt ist.According to the invention, the support structure has two bearing supports, which are spaced apart from one another. On these support beams is a grid floor on or on, which is made of flat support bars and flat filler bars.

Ein ebener Tragstab und ein ebener Füllstab im Sinne der Erfindung sind Stäbe, die vorzugsweise einen rechteckigen oder quadratischen Querschnitt aufweisen und besonders bevorzugt aus Stahlblech gefertigt sind.A planar support rod and a flat filler rod according to the invention are rods which preferably have a rectangular or square cross-section and are particularly preferably made of sheet steel.

Ein Tragstab im Sinne der Erfindung dient zur Aufnahme der Lasten, die auf den Gitterrostboden angeordnet werden. Ein Füllstab im Sinne der Erfindung stellt im Wesentlichen eine Verbindung zwischen den Tragstäben dar und verhindert, dass Gegenstände zwischen den Tragstäben durchrutschen bzw. vermindert die Verletzungsgefahr und erhöht die Trittsicherheit der Gitterrostböden. In der Regel weisen die Füllstäbe eine geringe Höhe auf als die Tragstäbe. Der Füllstab liegt vorzugsweise nicht auf den Auflageträgern auf. Die Füll- und die Tragstäbe sind vorzugsweise form- und/oder kraftschlüssig miteinander verbunden. Insbesondere sind die Trag- und die Füllstäbe miteinander verpresst. Dies erfolgt insbesondere dadurch, dass sowohl die Trag- als auch die Füllstäbe in den Verbindungsstellen geschlitzt werden, wobei dieser Schlitz etwas geringer bemessen ist, als die Dicke der jeweiligen Stäbe, so dass es beim Aufeinanderdrücken der Füllstäbe auf die Tragstäbe zu einer Verpressung der Stäbe kommt.A support rod according to the invention serves to accommodate the loads that are placed on the grate floor. A filler within the meaning of the invention is essentially a connection between the support rods and prevents objects from slipping between the support rods or reduces the risk of injury and increases the surefootedness of the grate floors. As a rule, the filler rods have a low height than the support rods. The filler rod is preferably not on the support carriers. The filling and the support rods are preferably positively and / or non-positively connected. In particular, the support and the filler rods are pressed together. This is done in particular in that both the support and the filler rods are slotted in the joints, this slot is dimensioned slightly smaller than the thickness of the respective rods, so that it when pressing the filler rods on the support rods to a compression of the rods comes.

Weiterhin erfindungsgemäß verlaufen die Tragstäbe parallel zu den Auflageträgern.Furthermore, according to the invention, the support rods extend parallel to the support carriers.

Vorzugsweise weist der Gitterrostboden mindestens ein Verstärkungsprofil auf, das sich besonders bevorzugt an seinem ersten oder zweiten Ende befindet. Ganz besonders bevorzugt weist der Gitterrostboden jeweils ein Verstärkungsprofil an seinem ersten und an seinem zweiten Ende auf.Preferably, the grate floor has at least one reinforcing profile, which is particularly preferably located at its first or second end. Most preferably, the grate floor has a respective reinforcing profile at its first and at its second end.

Vorzugsweise erstreckt sich das Verstärkungsprofil im Wesentlichen zwischen den Auflageträgern. Ganz besonders bevorzugt weist das Verstärkungsprofil an seinem linken und an seinem rechten Ende Anschlagflächen auf, die mit den Auflageträgern zusammenwirken und als Verrutschsicherung des Gitterrostbodens gegenüber den Auflageträgern dienen.Preferably, the reinforcing profile extends substantially between the support beams. Most preferably, the reinforcing profile at its left and at its right end stop surfaces, which cooperate with the support beams and serve as anti-slip protection of the grid floor against the support beams.

Insbesondere ist die Umrandung als U-Profil ausgestaltet, das die Trag- bzw. Füllstäbe an ihren Enden umgreift.In particular, the border is designed as a U-profile, which surrounds the supporting or filler rods at their ends.

Ganz besonders bevorzugt sind die Umrandung und die Verstärkung teilweise einstückig ausgeführt. Dies ist insbesondere an dem ersten und/oder an dem zweiten Ende des Gitterrostbodens der Fall.Most preferably, the border and the reinforcement are made partially in one piece. This is the case in particular at the first and / or at the second end of the grid floor.

Vorzugsweise sind die Füllstäbe nur teilweise mit den Umrandungen stoffschlüssig verbunden, d.h. es reicht aus, wenn lediglich einige Trag- bzw. Füllstäbe mit der Umrandung beispielsweise verschweißt sind. Bei Gitterrostböden gemäß dem Stand der Technik müssen zumindestens alle Tragstäbe mit der jeweiligen Umrandung verschweißt werden, was bei der erfindungsgemäßen Tragstruktur nicht nötig ist.Preferably, the filler rods are only partially bonded to the borders, i. it is sufficient if only some support or filler rods are welded to the border, for example. In the case of ground gratings according to the prior art, at least all supporting bars must be welded to the respective border, which is not necessary in the supporting structure according to the invention.

Vorzugsweise werden die Gitterrostböden der Tragstruktur aus Stahlblech, vorzugsweise aus feuerverzinktem Stahlblech, gefertigt.The grate floors of the support structure are preferably made of sheet steel, preferably of hot-dip galvanized sheet steel.

In einer weiteren bevorzugten Ausführungsform kann die Belastbarkeit der Gitterrostböden durch unterschiedliche Längen bei ansonsten identischen Abmaßen variiert werden. Dadurch können die jeweiligen Gitterrostböden innerhalb der Tragstruktur leicht ausgetauscht werden und es ergeben sich keine Versprünge innerhalb der Tragstruktur. Die Tragstruktur kann einfach auf die jeweils benötigte Belastbarkeit angepasst werden.In a further preferred embodiment, the load capacity of the grate floors can be varied by different lengths with otherwise identical dimensions. As a result, the respective grate floors can be easily replaced within the support structure and there are no jumps within the support structure. The support structure can be easily adapted to the required load capacity.

In einer bevorzugten Ausführungsform ist die Tragstruktur eine Treppenstufe. In diesem Fall liegt ein Gitterrostboden an zwei Wangen an oder auf diesen auf und ist vorzugsweise mit diesen form-, kraft- und/oder formschlüssig verbunden. Der Gitterrostboden weist ebene Tragstäbe und ebene Füllstäbe auf, wobei die Tragstäbe parallel zu den Auflageträgern verlaufen.In a preferred embodiment, the support structure is a step. In this case, a grate floor on two cheeks or on these and is preferably connected to these form, force and / or positive. The grate floor has flat support rods and flat filler rods, wherein the support rods extend parallel to the support beams.

Vorzugsweise weist der Gitterostboden an seinem vorderen und/oder hinteren Ende ein Verstärkungsprofil auf. Weiterhin bevorzugt ist, insbesondere parallel zu dem Verstärkungsprofil eine Sicherheitsantrittskante angeordnet.Preferably, the grid floor at its front and / or rear end on a reinforcing profile. Furthermore, it is preferable that a safety leading edge is arranged, in particular parallel to the reinforcing profile.

In the following, the invention is based on the FIGS. 1 to 7 explained. These explanations are merely exemplary and do not limit the general inventive concept.
  • FIG. 1 shows the support structure according to the invention in three views.
  • FIG. 2 shows the support situation between the grate floor and the support.
  • FIG. 3 shows the reinforcement profile integrated in the border.
  • FIG. 4 shows another detail of the reinforcement.

Figur 1 zeigt die erfindungsgemäße Tragstruktur in drei Ansichten. Diese besteht aus zwei parallel laufenden Auflageträgern 1, auf denen ein Gitterrostboden 2 aufliegt. Dieser Gitterrostboden weist Tragstäbe 3 auf, die sich parallel zu den Auflageträgern 1 erstrecken. Senkrecht zu diesen sind Füllstäbe 4 angeordnet, die mit den Tragstäben form- und/oder kraftschlüssig, insbesondere durch Verpressen, verbunden sind. Die Füllstäbe weisen eine geringere Höhe H auf als die Tragstäbe und dienen insbesondere zur Verbesserung der Trittsicherheit, der Unfallverhütung und um zu vermeiden, dass größere Gegenstände durch den Gitterrost fallen. Die Trag- und die Füllstäbe sind eben, weisen also keine Ein- und keine Ausbuchtungen auf. Sie sind aus ebenem Stahlblech gefertigt. Der fertiggestellte Gitterrostboden wird anschließend verzinkt. FIG. 1 shows the support structure according to the invention in three views. This consists of two parallel bearing supports 1, on which a grate floor 2 rests. This grate floor has support rods 3, which extend parallel to the support beams 1. Perpendicular to these filler rods 4 are arranged, which are positively and / or non-positively, in particular by pressing, connected to the support rods. The filler rods have a lower height H than the support rods and are used in particular to improve slip resistance, accident prevention and to avoid that larger objects fall through the grid. The support and the filler rods are flat, so have no inputs and no bulges. They are made of flat sheet steel. The finished grate floor is then galvanized.

Desweiteren weist der Gitterrostboden an seinem ersten und an seinem zweiten Ende jeweils ein Verstärkungsprofil 5 auf, das sich im Wesentlichen zwischen den beiden Auflageträgern 1 erstreckt und zur Erhöhung der Durchbiege-Stabilität des Gitterrostbodens dient. Das Verstärkungsprofil weist an seinem linken und an seinem rechten Ende jeweils eine Anschlagfläche 8 auf, die zum einem als Verrutschsicherung des Gitterrostbodens gegenüber den Auflageträgern dient, die aber auch als Führung beim Aufsetzen des Gitterrostbodens auf die Auflageträger vorteilhaft ist. Das Verstärkungsprofil verjüngt sich von den Tragstäben ausgehend.Furthermore, the grate floor at its first and at its second end in each case a reinforcing profile 5, which extends substantially between the two support beams 1 and serves to increase the deflection stability of the grid floor. The reinforcing profile has at its left and at its right end each have a stop surface 8, which serves as a slip-off protection of the grid floor against the support beams, the but also as a guide when placing the grate floor on the support carrier is advantageous. The reinforcing profile tapers from the support rods.

Der Gitterrostboden weist eine Breite B auf, die durch den Abstand zwischen den Auflageträgern definiert wird. Durch eine Variation der Länge L kann die Tragfähigkeit der Gitterrostböden an die jeweilige Belastungssituation angepasst werden. Je höher die Belastung der Gitterrostböden ist, desto geringer muss die Länge L gewählt werden. Mit der erfindungsgemäßen Tragstruktur ist es möglich Gitterrostböden zur Verfügung zu stellen, die bei gleicher Belastbarkeit ein geringeres Gewicht als Gitterrostböden gemäß dem Stand der Technik aufweist. Die Gitterrostböden der erfindungsgemäßen Tragstruktur sind mit einem Automaten schweißbar.The grate floor has a width B, which is defined by the distance between the support beams. By varying the length L, the load capacity of the grate floors can be adapted to the respective load situation. The higher the load of the grate floors, the lower the length L must be selected. With the support structure according to the invention, it is possible to provide grate floors available, which has the same load capacity lower weight than the grid floor according to the prior art. The grate floors of the support structure according to the invention are weldable with a machine.

Figur 2 zeigt ein Detail der Auflagesituation. Es ist zu erkennen, dass die Anschlagfläche 8 an die Rundung der rechten oberen Ecke des Auflageträgers 1 angepasst ist. Desweiteren ist zu erkennen, dass der Gitterrostboden eine U-förmig geformte Umrandung 9 aufweist. Weiterhin ist in dieser Ansicht deutlich zu erkennen, dass die Füllstäbe lediglich ein Drittel bis 50 % der Höhe der Tragstäbe aufweisen. FIG. 2 shows a detail of the edition situation. It can be seen that the stop surface 8 is adapted to the rounding of the upper right corner of the support carrier 1. Furthermore, it can be seen that the grid floor has a U-shaped outline 9. Furthermore, it can be clearly seen in this view that the filler rods have only one third to 50% of the height of the support rods.

Figur 3 zeigt die Umrandung 9 im Bereich des ersten und/oder zweiten Endes des Gitterrostbodens. In diesem Bereich sind das Verstärkungsprofil 5 sowie die Umrandung 9 einstückig hergestellt, was insbesondere die Herstellung des Gitterrostbodens vereinfacht aber auch dessen Stabilität erhöht. FIG. 3 shows the border 9 in the region of the first and / or second end of the grid floor. In this area, the reinforcing profile 5 and the border 9 are made in one piece, which in particular simplifies the production of the grate floor but also increases its stability.

Figur 4 zeigt noch einmal ein Detail der Umrandung. Es ist zu erkennen, dass die Umrandung aus vier U-förmig gebogenen Teilen gefertigt ist, die im Eckenbereich auf Gehrung geschnitten sind. FIG. 4 shows again a detail of the border. It can be seen that the border is made of four U-shaped bent parts, which are mitred in the corner area.

In den Figuren 5a und 5b sind zwei unterschiedliche Belastungssituationen eines Regalfachs dargestellt. Dieses Regalfach weist eine Länge von 2700 mm und eine Breite, d.h. der Abstand zwischen den Auflageträgern, von 1100 mm auf. Die Höhe H der Tragstäbe beträgt 20 mm. Die Höhe des Verstärkungsprofils beträgt 48 mm.In the FIGS. 5a and 5b Two different load situations of a shelf are shown. This shelf has a length of 2700 mm and a width, ie the distance between the support beams, of 1100 mm. The height H of the support rods is 20 mm. The height of the reinforcement profile is 48 mm.

In Figur 5b ist dasselbe Regalfach mit drei Gitterrostböden ausgelegt, die jeweils eine Länge 890 mm aufweisen. Alle anderen Maßen sind in Vergleich zu den Gitterrostböden gemäß Figur 5a unverändert geblieben. In diesem Fall beträgt ist die zulässige Flächenlast höher als bei der Variante gemäß Figur 5a, obwohl das Gewicht der Gitterrostböden im Vergleich zu der Ausführung gemäß Figur 5a im Wesentlichen unverändert ist.In FIG. 5b The same shelf is designed with three grate shelves, each with a length of 890 mm. All other dimensions are in comparison to the grate floors according to FIG. 5a remained unchanged. In this case, the permissible surface load is higher than in the variant according to FIG. 5a although the weight of the gratings compared to the design according to FIG. 5a is essentially unchanged.

Das Beispiel gemäß Figur 5 zeigt, dass es in einfachster Weise möglich ist, die benötigte Tragfähigkeit des jeweiligen Regalfachs durch eine Variation der pro Regalfach eingelegten Gitterrostböden zu erreichen. Dies war in der Vergangenheit nur durch Gitterrostböden mit einer unterschiedlichen Höhe H möglich, wodurch sich Versprünge innerhalb des Regales ergeben haben.The example according to FIG. 5 shows that it is possible in the simplest way, to achieve the required carrying capacity of the respective shelf by a variation of the per shelf shelves inserted. In the past this was only possible with grate floors with a different height H, which resulted in projections within the shelf.

Figur 6a zeigt eine Draufsicht der erfindungsgemäßen Tragstruktur als Treppenstufe. Diese weist rechts und links Wangen auf, an denen der Gitterrost angeordnet ist. Die Tragstäbe 3 erstrecken sich somit parallel zu den Wangen 1, während die Füllstäbe 4 quer dazu angeordnet sind. FIG. 6a shows a plan view of the support structure according to the invention as a step. This has right and left cheeks on which the grid is arranged. The support rods 3 thus extend parallel to the cheeks 1, while the filler rods 4 are arranged transversely thereto.

Wie insbesondere den Figuren 6b und 6c entnommen werden kann, weist die Treppenstufe bedarfsweise vorne und/oder hinten jeweils ein Verstärkungsprofil 5 auf, das jeweils form-, kraft- und/oder stoffschlüssig mit jeweils beiden Wangen 1 verbunden ist. Der Lasteintrag der Tragstäbe 3 erfolgt somit direkt in die Verstärkungsprofile 5, vorzugsweise ohne zusätzliche tragende Schweißverbindung. In ihrem vorderen Bereich weist die Treppenstufe darüber hinaus vorzugsweise eine Antrittskante 10 auf, mit der Verletzungen an der Treppenstufe verhindert werden sollen. Die Antrittskante ist vorzugsweise einstückig mit einem Verstärkungsprofil 5 vorgesehen. In dem vorliegenden Fall ist die Antrittskante jedoch ein separates Bauteil. Die Wangen 1 weisen jeweils zwei Bohrungen 11 auf, mit denen die Treppenstufe mit allen anderen Elementen befestigbar ist.As in particular the Figures 6b and 6c can be removed, the step has, if necessary, front and / or rear on each a reinforcing profile 5, which is in each case positively, positively and / or materially connected to both cheeks 1. The load entry of the support rods 3 thus takes place directly in the reinforcing profiles 5, preferably without additional load-bearing welded connection. In addition, in its front region, the step step preferably has a leading edge 10 with which injuries to the step are to be prevented. The leading edge is preferably provided integrally with a reinforcing profile 5. In the present case, however, the leading edge is a separate component. The cheeks 1 each have two holes 11, with which the step with all other elements can be fastened.

Figur 7 zeigt die Treppenstufe gemäß Figur 6, wobei in dem vorliegenden Fall das vordere (linke) Verstärkungsprofil gleichzeitig die Antrittskante 10 ist. Ansonsten gelten die zu Figur 6 gemachten Ausführungen. FIG. 7 shows the step in accordance with FIG. 6 In the present case, the front (left) reinforcing profile is at the same time the leading edge 10. Otherwise, the apply to FIG. 6 made statements.
