The invention provides a system, a method and a device for manufacturing a truss of framework from joined bar-elements and connection-elements inserted therebetween at joints, the bar-elements consisting of at least one segment of a material of high-growing plants, and the connection-elements consisting of a rigid, regenerative material. The ends of the bar-elements and/or the connection-elements are machined to exhibit surfaces of geometrical bodies, such that in the area of the joint, on each of the two bodies there is provided one surface which is a cylinder, cone, prism or pyramid, at least in selected areas, as well as another complementary surface which can be respectively plugged together with adjoining surfaces. The device comprises a cutting tool for machining of at least one connection-element and/or of the ends of bar-elements which are to be joined thereto. |
