FIELD: construction.
SUBSTANCE: power transmission line stand is made as a hollow pillar of prestressed reinforced concrete. It has a rectangular cross section, and a longitudinally transverse reinforcement, available in the stand, is made of two identical units, every of which consists of a prestressed reinforcement wire, divided into two groups, which are remote from each other relative to a transverse axis of the stand cross section and are arranged symmetrically to it and in a row, which is parallel to a longitudinal axis of the stand cross section, which is wound with a flat spiral, besides, the above specified units are arranged symmetrically relative to the longitudinal axis of stand cross section, and the longitudinal reinforcement is a wire of 5 mm in diameter, and flat spirals are made of 3 mm wire.
EFFECT: development of a reliable, simple and manufacturable reinforced concrete stand with reduced weight.
