<p>A method for the fabrication of a double-walled construction element and the construction element obtained through that method, wherein said method includes the following steps:… - machining an unexpanded solid block (3) in honeycomb to predetermined dimensions in such a way that the honeycomb in expanded situation fills up the total space between the outer and inner tubular elements (1, 2), said expanded honeycomb (3) being in close contact with adjacent surfaces of the inner and outer tube respectively,… - expanding the machined block,… - fixing one face of the expanded honeycomb to the inner tube (1),… - calibrating the opposite face of the honeycomb,… - assembling the outer tube (2) over said opposite face,… - fixing of the opposite face of the honeycomb to the outer tube. …<??>A construction element as achieved with said method represents a very high resistance to fatigue-load under dynamic charges, since the honeycomb, its walls extending normal or substantially normal to said tube faces, has a diverging effect of the charges.</p> |
