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.
