FIELD: construction.
SUBSTANCE: device to reinforce beam structures includes prestressed four-branch braced ties fixed at ends of the beam in its upper part, resting in areas of bending at hinged cylindrical supports with a pad, installed in the lower part of the beam and tightened by yokes. In the upper end zone of the beam there are angular profiles installed onto a footing, where braced ties are fixed as a tightened assembly.
EFFECT: increased bearing capacity due to balance of forces in all bands of a braced system.
