FRP PIPE UNIT FOR REINFORCING A CONCRETE STRUCTURE AND A CONCRETE STRUCTURE THEREWITH WITH IMPROVED COHERENCE BETWEEN CONCRETE AND AN FRP PIPE

摘要

PURPOSE: An FRP pipe unit for reinforcing a concrete structure, and a concrete structure therewith are provided to prevent a brittle failure by improving resistivity against sagging and buckling of a concrete structure.;CONSTITUTION: An FRP pipe unit(121) for reinforcing a concrete structure comprises a FRP pipe and a coherence strengthening unit. The FRP pipe is integrally formed in a concrete slab layer, and prevents the concrete slab layer from sagging. The coherence strengthening unit is integrally formed in the outer surface of the FRP pipe, and strengthens the coherence between the FRP pipe and concrete placed outside the FRP pipe.;COPYRIGHT KIPO 2010
