METHOD AND DEVICE FOR STRENGTHENING BENT FERROCONCRETE BEAMS

摘要

FIELD: construction. SUBSTANCE: metal diaphragm whose width corresponds to width of the beam is secured to ends of the beam. Dismountable shields are mounted on sides of the beam. A space between the beam, diaphragm and shields is filled with expanding concrete. The shields have coaxial openings through which pipes are passed. Length of the pipes corresponds to width of the beam. Locking members , e.g., bolts with nuts, are positioned within the pipes. The bottom part of shields are provided with arc-like guides with sealing spacers. EFFECT: simplified method. 3 cl, 5 dwg
