METHOD FOR STRENGTHENING OF SUPPORTING UNIT IN GIRDER STRUCTURE Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: method relates to strengthening of disrepaired unit in girder structure. According to method, supporting member is installed under lower face of structure being strengthened. Thrust member is installed on end face of structure being strengthened. They are connected together by two cantilever main beams. Then clearance is created between cantilevers of main beams and cross-member. Clearance is then removed by tightening of fastening bolts, and by arrangement created is resilient strengthening support, thus partly or completely relieving supporting pad with simultaneous compression of anchoring zone of girder structure. Application of aforesaid method improves reliability, safety, and economic efficiency in strengthening of supporting unit in girder structure. EFFECT: higher efficiency. 25 cl, 41 dwg
