METHOD TO UNLOAD EMERGENCY REINFORCED CONCRETE CANTILEVER THAT EXHAUSTED ITS BEARING CAPACITY AS RESULT OF CONCRETE AND REINFORCEMENT CORROSION Russian patent published in 2011 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: main cross beam is mounted, a pair of beam balancers covering column at both sides and balancing on the main traction rods are suspended to cross beam ends at main traction rods hanging along sides of emergency cantilever. Short arms of this pair of balancers are brought and rested at the bottom under supports of adjacent crane beams, and long arms of this pair are rested at the bottom against ends of thrust beams protruding beyond sides of column via adjustment nuts of traction rods. Accordingly middle parts of these beams are rested at the bottom against fixed supports of angles welded to bare working reinforcement of column at its back side. In gap between crane beams and near front face of upper part of column, next to centre of gravity of lower part of column, basement is locally fixed, and low modular pad is rested against it, for instance, from conveyor belt.

EFFECT: full recovery of building carcass column serviceability without interruption of production process.
