Brace sheet wall containing piles and closing elements alternating with piles with T-shaped in cross-section interlocking ledges, and each pile includes a pipe and pair of profile elements welded to pile with hollowness formation in which shelves of T-shaped interlocking ledges of adjacent closing elements are placed. Each pile is supplied by additional pipe connected to the first pipe by means of welding. Profile elements are placed singly in internal hollowness of each pipe, thus in each pipe a longitudinal open cut is executed and through it a wall of T-shaped interlocking ledge of adjacent closing element is passed. Width of cut is less than flange width of mentioned interlocking ledge.

EFFECT: increase of load-carrying capacity of brace sheet wall and protection of clasps against external impacts.
