A MULTICHAMBER STRUCTURAL ELEMENT AND A MULTICHAMBER STRUCTURAL ELEMENT MANUFACTURING METHOD
The object of the invention is a multichamber structural element manufacturing method which for forming a multichamber structural element with chamber profiles (1) extending radially from the center defined by the connection of the chamber profiles (1) comprises the following steps: at least three chamber profile preforms (2) are provided, wherein each chamber profile preform (2) comprises two walls (3) made of a sheet of metal material and arranged with respect to each other in substantially parallel planes with a gap retained between them, wherein the edges of the individual walls (3) converge, and wherein a valve element (6) is arranged on at least one wall (3); the unconnected wall (3) edges of each of the chamber profile preforms (2) are sealed with a seal (5) for forming a closed hermetic empty inner space of the chamber profile preform (2); a fluid under pressure is introduced through the valve element (6) into the inner space of the chamber profile preform (2) for forming a deformed chamber profile (1), at least three chamber profile preforms (2) or chamber profiles (1) are connected in the area of the corresponding inner edges of the chamber profile preform (2) or the chamber profile (1), proximal with respect to the connection axis (4), along at least part of the inner edges. The object of the invention is also a multichamber structural element.
