SLAB REINFORCEMENT METHOD USING H-SHAPED STEEL

摘要

PROBLEM TO BE SOLVED: To provide a slab reinforcement method using H-shaped capable of improving bearing force as well as rigidity of an existing RC rigid-frame viaduct and implementing a measure against vibration by strengthening connections between slabs as well as between the slab and a beam through simple construction.

SOLUTION: A slab reinforcement method using H-shaped steel constructs: an additional beam for a slab 1 made of H-shaped steel 2 arranged at a lower surface 1A of the slab 1; driving type hole-in anchors 5 to be driven into the slab 1; and a screen-shaped edge section reinforcement plate 7 which is arranged to install hole-in anchors 8 connecting the same with a beam 4 of the slab 1 and is connected with an edge section of the additional beam by a connection member 6.
