CONSTRUCTION METHOD OF A COLUMN STRUCTURE USING MULTI-LAYER FRP WIRE JACKETS CAPABLE OF EFFECTIVELY REINFORCING A COLUMN STRUCTURE

摘要

PURPOSE: A construction method of a column structure using multi-layer FRP wire jackets is provided to prevent damage to the surface of a column by not requiring a device for fixing an anchor to the surface of the column.;CONSTITUTION: A construction method of a column structure using multi-layer FRP wire jackets is s follows. One end of an FRP wire touches the surface of a column structure(100), and the FRP wire surrounds the column structure. The FRP wire is fixed to the surface of the column structure using a high-strength adhesive. Tensile force is applied to the FRP wire to wind the FRP wire around the surface of the column structure. An FRP wire jacket(A1) is formed on the column structure by attaching the other end of the FRP wire to the surface of the column structure. Multiple FRP wire jackets are formed by repeating the processes. Epoxy is spread on the outermost FRP wire jacket.;COPYRIGHT KIPO 2013
