FIELD: construction.
SUBSTANCE: invention relates to bridge building. The method of reinforcing includes the installation of gussets in a crack zone and their rigid connection to a metal element. Initially the crack is countersunk at the angle 60-80° to the depth 2-3 mm, the soldering paste is applied on the countersunk crack, then the gussets are placed with the gap within 0.4-0.5 mm, pressing the latter to the metal element with the force 0.1-0.2 MPa with further local heating up to solder melting temperature.
EFFECT: prevention of development of cracks and reinforcing of walls of metal main beams and longitudinal beams of bridge superstructures.
