FIELD: construction engineering; laying underwater pipe lines, pipe lines floating in water-encroached trenches and in marshes.
SUBSTANCE: proposed brace frame is made from rolled metal in form of flat closed polygonal framework; frame includes girders and brace members interconnected by means of locks; each end of girder or brace member is provided with lock which is bent in plane of frame at angle relative to girder or brace member for connection with end of brace member or girder; connection units of girder or brace member are located on one side from its longitudinal axis.
EFFECT: facilitated procedure of manufacture; reduced number of welds; reduced scope of machining.
