The invention relates to a system, a method, and a device for producing a supporting framework or a rigid girder comprising rods (4) and connecting elements which are optionally arranged therebetween at connecting points (1). The rod-shaped elements (4) are respectively made of at least one segment of a material stemming from climbing plants(e.g. bamboo) and the connecting elements (1) are made of a solid, re-newable material (e.g. wood). According to the invention, the ends of the rod-shaped elements (4) and/or the connecting elements (1) are treated in such a manner that they comprise surfaces extending at least in certain areas along clearly defined geometric bodies such that in the connecting area of a rod-shaped element and a connecting element or another rod-shaped element, each of the bodies comprise respectively a surface which extends at least in certain areas along the covering surface of a cylinder, conical-shaped element, prism or a pyramid and at least partially along a hollow cylinder, conical-shaped element, prism and/or hollow pyramid. Said surfaces are or can be assembled according to a coupling process with adjacent surfaces. The tool used therefor consists of at least one tool embodied as a removing tool, especially as a cutting tool for machining at least one connecting element and/or the ends thereof in order to obtain connectable rod-shaped elements. |
