Abstract

The invention relates to a rod-shaped base body with at least one bearing surface which can be brought to bear against at least one counter-bearing surface of a bearing device for fastening to a further rod-shaped base body and/or a functional component for forming a framework. The rod-shaped base body can be a fiber-composite material, particularly carbon-fiber-reinforced plastic, and the rod-shaped base body has a recess as positioning mark determining the position of the further base body and/or the functional component in relation to the rod-shaped base body in the framework by the positive engagement due to the at least one bearing surface and at least one counter-bearing surface bearing against one another. The invention also includes a framework system having a rod-shaped base body of this type. The object of the invention is additionally achieved by a method for producing a rod-shaped base body of this type.

First claim

The invention claimed is:

1. A rod-shaped base body, particularly for arranging functional components, with at least one bearing surface which can be brought to bear against at least one counter-bearing surface of a bearing device of a connecting device for fastening a further rod-shaped base body and/or a functional component to the rod-shaped base body for forming a framework,
wherein the rod-shaped base body is produced from a fiber composite material, particularly carbon-fiber-reinforced plastic, and the rod-shaped base body has a recess as a positioning mark, which provides the at least one bearing surface for forming a positive fit with at least one counter-bearing surface of the further base body and/or the functional component,
wherein the bearing surface runs in a circumferential direction of the rod-shaped base body,
wherein the rod-shaped base body has a polygonal cross section, and
wherein the fiber composite material comprises a plurality of fibers, wherein fibers aligned with the recess extend around or under the recess without being interrupted by the recess.

2. The rod-shaped base body according to claim 1 , wherein the at least one bearing surface is formed by a shaped section of the rod-shaped base body.

3. The base body according to claim 2 , wherein the shaped section is a bead which in particular annularly runs around a main axis of extension of the rod-shaped base body, wherein at least one boundary surface of the bead forms at least one of the bearing surfaces which interacts with one counter-bearing surface.

4. The rod-shaped base body according to claim 3 , wherein boundary surfaces of the bead form a stop surface which, while bearing against a counter-contact surface of the at least one counter-bearing surface, fixes a position of the bearing device connected to the rod-shaped base body along the main axis of extension of the rod-shaped base body.

5. The rod-shaped base body according to claim 3 , wherein boundary surfaces of the bead form at least one stop surface which, while bearing against a counter-contact surface of the at least one counter-bearing surface, fixes and angular position of the bearing device connected to the rod-shaped base body with respect to an axis of rotation of the rod-shaped base body running parallel to the main axis of extension.

6. The rod-shaped base body according to claim 3 , wherein the rod-shaped base body has a triangular, hexagonal or octagonal cross section arranged transversely to the main axis of extension of the rod-shaped base body, at least in a region of the bead.

7. The rod-shaped base body according to claim 2 , wherein the shaped section is constructed as a spherical segment, an inner surface of which provides the bearing surface which interacts with the at least one counter-bearing surface.

8. The rod-shaped base body according to claim 1 , wherein the positioning mark is a hole with an inner wall which provides the bearing surface which interacts with the counter-bearing surface.

9. A framework system for arranging functional components, in particular having a rod-shaped base body according to claim 1 .
