METHOD OF REINFORCING BOREHOLE PERIPHERAL PART FOR EXISTING CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method of reinforcing a borehole peripheral part for an existing concrete structure having excellent workability, obtaining a reinforcing effect of high quality regardless of the construction skill of a constructor and securing a sufficient reinforcing effect even with a change in surrounding environment.;SOLUTION: In the method of reinforcing a peripheral part 1b of a borehole 1a formed after laying for a skeleton 1 of the existing concrete structure, a fiber reinforced plastic molded plate 10 having an opening 10a including at least the borehole 1a and having a fiber layer laminated so that at least the intersecting directions of fiber are symmetric with respect to the center cross section in a plate thickness direction, is used, and the opening 10a is adjusted to the borehole 1a to stick the fiber reinforced plastic molded plate 10 to the peripheral part 1b through an adhesive.;COPYRIGHT: (C)2005,JPO&NCIPI
