Description

The present invention relates to a modular system comprising at least one connecting device and at least one rod, a connecting device and a rod for a supporting structure.

In known modular systems (modular building systems) of connecting devices and rods for the formation of single-shell tensile structures are arranged between the bars for their connection nodes as connecting means, which may consist of a cast material. The bars are i. d. R. formed of tubular steel profiles, which can be screwed or welded to the prefabricated connecting devices (casting node). In order to be able to provide different shapes, star-shaped casting knots are known from the prior art which have, for example, six end faces for fastening the respective tubular steel profiles (rods).

In the known conventional modular construction systems of nodes and rods for the formation of single-shell structures, it has now turned out to be disadvantageous that their geometric flexibility is limited. In addition, the visual appearance is disturbing due to clearly visible joints in the joint area between nodes and bars.

The invention has the object of developing a modular system of at least one connecting device and at least one rod for a Tragwerkkonstrukts, in particular for a single-shell tensile structure to the effect that the geometric flexibility is increased and the visual appearance is improved.

The object is achieved by a modular system consisting of at least one connecting device and at least one bar for a supporting structure according to the independent protection claim 1. With regard to the connecting device, the object is achieved by a connecting device for a modular system of connecting devices and rods for a supporting structure according to the independent protection claim 8. With respect to the rod, the object is achieved by a rod for a modular system of connecting devices and rods for a structural construct according to the independent protection claim 15.

In particular, the object is achieved by a modular system consisting of at least one connecting device and at least one rod, which protrudes at least one front attachment opening on one of the connecting device or rod for introducing a protruding fastening element, which protrudes from the end face of the other of the connecting device or rod, such that after insertion, the end faces adjoin one another, and at least one handling opening, which is arranged and designed such that it allows access to the protruding fastening element and its manipulation in order to anchor the protruding fastening element in the fastening opening.

The advantages of the solution according to the invention are obvious.

Characterized in that the connection between the connecting device and the rod is accessible through a handling opening, this connection, in particular a connection by means of a screw or the like, can be produced in a simple manner. In this case, the connection between the connecting element and the rod is largely geometrically fluid in one another and is optically separated by a hairline, which improves the visual appearance.

The at least one connecting device can in this case be produced in an advantageous manner in the casting process. A casting mold for such a connection device produced by casting can be modeled in this case, for example, in a CAD system and subsequently produced in the 3D printing process. As a result, an extremely large geometric flexibility is possible, which may be formed by the possible cost-effective production in the 3D printing process, the corresponding mold for the connection device as a lost form, since the advantages that provide the enormous flexibility, resulting from the increased cost of materials, far outweigh the disadvantages.

By such a variable and individually customizable by the printing design of the geometry can be generated only by an almost imperceptible hairline transition formed between the formed as a cast node connection device and the front end attached rod.

Advantageous developments of the solution according to the invention are specified in the dependent claims.

For example, it is possible for the handling opening to be formed in a side wall of the connecting device that is different from the front side. However, it is also possible that the handling opening in a different side of the end wall of the rod is trained. In both cases, a simple handling (manipulation) of the protruding fastening element, which is formed for example by a screw, possible.

According to a further aspect of the invention, it is provided that the handling opening is designed to be closable. This forms an optical advantage when the handling opening is formed in the viewing direction on the supporting structure. In any case, a closable trained handling opening has the advantage that the weather resistance is increased.

According to a further aspect of the invention, it is provided that a fastening plate is provided on the end face of the connecting device. Alternatively or additionally, it is provided that a fastening plate is provided on the front side of the rod. In any case, the at least one attachment opening is formed in such a mounting plate. By providing such a mounting plate with mounting opening a visual and technical conclusion of the respective end face is possible in a simple manner, which increases the durability of the modular system.

According to a further aspect of the invention, it is provided that the at least one fastening opening is formed as a passage opening for passing through the protruding fastening element. In particular, in this case, the attachment opening is formed as a through hole. Such a through hole allows access from the respective handling opening and thus a simple manipulation (rotational movement or the like) of the protruding fastening element. In addition, the structure is simplified in this case, since the connecting device, the rod and the at least one protruding fastener can be supplied individually and mounted on site, whereby a demand-based adjustment is possible.

According to a further aspect of the invention, it is provided that the at least one fastening opening is provided with an engagement element for anchoring to the inserted protruding fastening element. In particular, the attachment opening is provided with an internal thread formed in a blind hole. Such a blind hole and in particular also such an internal thread can be produced easily. This provides a particularly effective and cost-effective option for such a modular system.

The invention also relates in each case to individual connection devices for a modular system of connecting devices and rods with the respective advantageous developments described above.

The invention also relates to a rod for a modular system of connecting devices and rods with the advantageous developments described above.
