Method of manufacture of elements of the metal walls formed of sheet piles and / or girders laterally, elements realized by this process and the walls formed of these elements.

摘要

The invention relates to the manufacture of girders (10) having an H-section (I-section) and which are intended to be clipped together laterally on each side, with a girder of the same type or with a shaped or flat sheet pile. In order to eliminate the problem of the rolling of locks in the girders, there are produced, by rolling, thin strips in the form of claws (12, 14) which are welded along the opposite edges of at least one girder flange.
