| (57) This invention relates to a method for producing building elements, and the resulting
building elements, in which the method comprises the following steps:
a) fastening of a plurality of coupling devices (3,4) along at least one intermediate
part (2), with an essentially equal mutual distance between them in the longitudinal
direction of the intermediate part(s), the coupling devices each being adapted to
couple two intermediate parts or one intermediate part (2) and one outer part (1),
b) using per se known equipment pulling the coupling devices (3,4) transversely of
the longitudinal direction of the intermediate parts, the intermediate parts thus
obtaining a zigzag shape, and
c) fastening of the outer parts (1) to the coupling devices (3) on each side of the
intermediate part(s) (2).
