Description

technical features

The present invention relates to a main carrier, which can not only be used for large spans due to its structure and its holes, but also has inventive features, since such main carriers are used both as a single and as a double pillar and overlap each other at any angle and Furthermore, they can be connected to each other at each of their constituents.

By using a single type of module, the new main carrier allows the construction of structures that previously required many different structural elements and which were associated with a great deal of time.

The main beams can be connected at any angle via their back or fixed by their flanks and edges, wherein the main carrier according to the invention are used both as a pillar and as a carrier, armored carrier or as beams and reinforced depending on the purpose of the respective construction may or not.

Furthermore, the main carrier can be completely dispensed with joining by welding because of this virtually unrestricted type of connection, so that large structures can now be constructed without using welding devices, as well as robust pillars which are connected to the carrier structure, and all kinds of reinforced beams and reinforcements, which are created simply by connecting the modules, the main beams being connected together by a single type of screw.

Conventionally, components designed specifically for each project are used for all metallic structural elements of buildings (such as houses, exhibition halls, industrial plants and greenhouses), covers and structural structures (such as for facades, solar farms and parking lots). Above all, this has the disadvantage that special components have to be developed for the construction of a specific metal structure, and individual components with high dimensional accuracy have to be manufactured from thick and heavy metal plates.

In addition, such systems require a large number of connecting parts and must be welded, stained and painted during the production and assembly phase. This makes the execution of the work very comprehensive and costly. Furthermore, due to their characteristics, the structures, which are often large in size, can only be lifted with the help of heavy duty cranes.

The construction of large industrial plants has always been associated with some problems. In particular, large gaps must be overcome or large gaps between pillars closed. Conventionally, this problem is solved by increasing the number of pillars, which, however, reduces the usable space. Another existing solution is the overlap of straps in the longitudinal direction or in the superimposition of straps with other vertical straps at a 90 ° angle.

• – Die Träger können einander in Längsrichtung überlagern, sodass es möglich ist, größere Spannweiten zu überbrücken. Diese Lösung gleicht herkömmlichen Lösungen, wobei jedoch in diesem Fall auch ein Überlappen entlang der kompletten Rückseite möglich ist.
• – Die Träger können einander in jedem beliebigen Winkel überlagern, sodass unzählige Möglichkeiten der Ausrichtung der Hauptträger bestehen, wodurch sich eine vergrößerte Anzahl von Verwendungsmöglichkeiten ergibt.
• – Die Träger können zu einem ebenen oder verstärkten Pfeiler umgeformt werden, sodass diese eine eigentlich nicht vorgesehene Rolle übernehmen können.
• – Die Träger können sowohl über die Rückseite (durch eine direkte oder umgekehrte Verbindung) als auch über die Kanten oder Flanken miteinander verbunden werden.
• – Die Träger können derart miteinander verbunden werden, dass entweder die Rückseite mit der Flanke oder der Kante, die Flanke mit der Flanke oder die Flanke mit der Kante verbunden wird, sodass unter normalen Umständen bei der Konstruktion einer bestimmten Struktur praktisch jede Art von Aufbau möglich ist.
• – Die Träger können einander in jedem beliebigen Winkel überlappen, einander überlagern oder miteinander verbunden werden, um Trägerstrukturen oder bewehrte Träger zu bilden.

However, the proposed invention seeks a much more far-reaching solution, the carrier or main carrier having the following properties:

• - The beams can overlap each other in the longitudinal direction, so that it is possible to bridge larger spans. This solution is similar to conventional solutions, but in this case also an overlap along the entire back is possible.
• - The carriers can overlap each other at any angle, so countless ways to align the main carrier, resulting in an increased number of uses.
• - The beams can be converted to a flat or reinforced pillar, so that they can take a role actually not intended.
• - The beams can be connected to each other via the back (by a direct or reverse connection) as well as over the edges or flanks.
• The supports can be connected to one another in such a way that either the back with the flank or the edge, the flank with the flank or the flank is connected to the edge, so that under normal circumstances virtually any type of construction is possible in the construction of a specific structure is.
• The supports may overlap one another at any angle, be superposed on each other, or be joined together to form support structures or armored supports.

In essence, the proposed invention provides an improved ability to bridge large spans while achieving substantial savings in the amount of material used by simplifying the manufacturing process and allowing the use of modular elements, with the same element being used in a variety of ways can be used both as a carrier, as a beam, reinforced carrier or as a solid pillar.

Additional elements (additional beams, pillars, reinforced beams or beams) can be added at any given time without having to make any changes or to have structural elements of the construction.

Furthermore, the invention considerably simplifies both storage and transport. The structures do not need to be welded and there is no need to handle their surfaces. Thus, by the invention, a much faster processing can be achieved.

The proposed invention is based on a carrier with a generally U-shaped profile, which is folded several times on its flanks and edges, which makes joining, overlapping and fixing extremely easy.

The main beam is made of a structural steel and in its usual design light and robust.

Over its entire length, the main beam has holes on both the back, flanks and edges, allowing for a plurality of elements to be fastened, connected and overlaid in different ways to construct pillars, beams and beams of varying lengths and anchoring at any angle is possible.

The structure of the main beam is extremely important for its multi-functionality: Due to the arrangement of the holes over the entire back, over the flanks and the edges as well as due to its U-shaped profile with a specially shaped angle structure, a variety of functions can be adopted.

Thus, during the assembly or construction of exhibition halls or other large-scale structures by means of the same main support all structural elements - and not only the carrier in longitudinal or vertical arrangement - are constructed and assembled by simply the anchoring angle is selected according to the holes, so this Process is much faster and easier.

In this way, the operation is not only simplified, but also much cheaper, on the one hand because this is accelerated and much less manpower must be used, but on the other hand also by the fact that only a single type of main carrier is used, all the functions which were previously taken over either by the girders, the beams, the reinforced girders or the pillars.

State of the art

The use of profile members made of a lightweight material and with holes that allow them to overlap one another to bridge large spans is relatively new.

Basically, only carriers are known from the prior art, which have holes in their end regions, over which a longitudinal overlapping of the carrier is made possible.

Thus, there are U-shaped beams whose ends have holes and which can be connected longitudinally with each other via their backs to bridge such large spans.

• – Sie ermöglichen kein Überlappen in anderen Winkeln als im 90°-Winkel;
• – außer einer Ausrichtung in Längsrichtung durch das Verbinden eines Trägers mit einem entsprechenden Träger, geradlinig und Rückseite an Rückseite, besteht keine weitere Ausrichtungsmöglichkeit;
• – es können keine Pfeiler konstruiert werden;
• – es besteht nicht die Möglichkeit des Überkreuzens oder Überlagerns von Elementen in unterschiedlichen Bereichen;
• – es sind keine modularen Erweiterungen in irgendeine Richtung möglich.

However, the features of such carriers are very limited compared to the features of the present invention:

• - They do not allow overlapping at angles other than 90 °;
• - Apart from a longitudinal orientation by connecting a carrier with a corresponding carrier, straight and back to back, there is no further alignment possibility;
• - no pillars can be constructed;
• There is no possibility of crossing or overlapping elements in different areas;
• - There are no modular extensions in any direction possible.

Description of the best embodiment of the invention

The invention is based on a main carrier of a structural steel or a similar substitute lightweight, robust material with a generally U-shaped structure. This "U" shape is the result of multiple folds starting from the back toward the edges. In particular, such folds between the flanks ( 2 B ) and the edges ( 3-b ) is provided along the entire length of the main carrier.

In fact, only the back ( 1 ) has a flat surface, which facilitates joining and fixing of the modules.

The flanks ( 2 ) have more or less pronounced folds ( 2 B ), which give a certain convexity to the entire length of the main beam. The edges ( 3 ) are bent, as well as over the entire length of the main carrier, positively bent ( 3-b ).

This bend facilitates the connection of the modules and achieves reinforced anchoring. Accordingly, the slight bending of the edge, which is provided over its entire length, when joining the edge with an edge (such as in 11 to see) or the edge with a flank (such as in 5 and 8th shown) when tightening the screws ( 4 ) for increased tension and strength. This also applies to connecting a flank to a flank (such as in 12-d shown).

On the main carrier three types of holes are provided over its entire length. These are either on the back ( 1-a ), on the flanks ( 2-a ) or at the edges ( 3-a ) intended. Such holes are all arranged in the longitudinal direction.

The holes on the back are intended to be used for an overlapping arrangement of two main carriers in the longitudinal direction, whereby a variety of lengths can be achieved, which are suitable to bridge very different spans. For this purpose, it is sufficient to overlap a main beam at each desired point in the longitudinal direction with another main carrier.

But also a connection over the backs with reverse orientation ( 9 ) is possible. Since the holes are arranged along the entire length of the main carrier, they allow overlapping or any other type of longitudinal connection to achieve any length.

Because the main beams are made of a lightweight and highly durable material, they can only overlap at the edges to bridge large spans, or they can overlap over larger portions for use for smaller spans.

To build stronger structures ( 12-b ), the main beams can overlap each other completely.

If the main carriers are reversed by facing each other in mirror image opposite to each other, they can cross each other at a 90 ° angle according to the most common embodiment ( 2 ), or they can, without being limited to a vertical orientation, form an intended angle ( 3 ).

It should be noted that the last possibility described is due to the positioning of the holes, because due to the holes which are arranged over the entire length of the edges, a reverse arranging and fixing of the main beams at any point ( 2 and 3 ) is possible.

The structure of the main beams is also crucial for their extraordinary functionality. By using this new type of metal structures, a single element can be used as a beam as well as a carrier or armored carrier, or optionally even be used as a pillar.

Although the main carrier in its most conventional form of use may also serve as a carrier by simply overlapping it with another main carrier along the back, many other design possibilities are provided within the scope of the invention that have been properly tested and described below.

Thus, the same main carrier can also serve as a pillar by two main carriers are arranged mirror-inverted to each other and joined together at the edges ( 6 ). It is also possible to overlap the arrangement just described by the same type of edge connection, so that a reinforced pillar (FIG. 7 ) arises. Furthermore, four star carriers can be used to form a star-shaped structure ( 8th ) arise by the flanks ( 2 ) of two carriers with the edges ( 3 ) are connected by two other carriers by means of screws.

In addition to the above-described superimposing the main carrier in the longitudinal direction, it is also possible to connect the main carrier on the outside together ( 4 Here, a main carrier is arranged perpendicular to another main carrier and connected thereto by the upper end of an edge ( 3 ) at the upper end of another edge via screws ( 4 ) in the corresponding holes ( 3-a ) are arranged, is fixed. Likewise, two main carriers can be interconnected perpendicular to each other via their inner side ( 5 Here, the connection between the edges of one and the flanks of the other main carrier via the corresponding holes ( 2-a ) consists.

The 9 . 10 and 11 show some of the execution options of this versatile main carrier. By appropriately selecting the holes and joining the edges, flanks or tops, it is possible to use the main support in the case of structural structures with large structures, such as exhibition halls, industrial facilities, warehouses and the like in very different ways.

In 12 , which shows the possibilities of superimposing or connecting main carriers only by way of example, some solutions are presented, such as the use of a single main carrier ( 12-a ) or a connection by overlapping the backsides ( 12-b ) for use as a support or beam or a compound for use as a pillar ( 12-c . 12-e and 12-f ) and other possible solutions ( 12-d . 12 g and 12-h ) with numerous connection possibilities.

The individual modules are connected to each other via screws. These screws can also be used on the edges (such as in 2 . 3 and 11 shown), as well as on the flanks (such as in 5 . 8th . 10 and 12-d shown) or at the back.

In fact, the invention uses only a single type of main carrier and a single type of screw. Therefore, the main carrier can be used both as a carrier, as a beam, as a reinforced support or as a pillar use, wherein for each of the holes only a single type of screw is used.

The construction is completed as soon as all connections are fixed with the help of the screws. At no time is there a need for welding and structural elements are created with only a single type of support.
