FIELD: construction.
SUBSTANCE: pipe-rod in spatial structures includes a polymer pipe and a bent-welded steel channel. The profile has a shape of triangle in the cross section and is installed into the pipe for its whole length. Tops of the channel are in tight contact with the inner surface of the pipe. Notches are provided at the profile ribs.
EFFECT: increased rigidity of a rod, resistance solution for high static and dynamic loads and increased bearing capacity.
