CONCRETE POLE AND METHOD OF REINFORCING SAME

摘要

A concrete pole having an improved elasticity by reinforcement of a simple ,construction is provided. A reinforcing layer 11 of a fiber-reinforced composite material is provided on part of the outer circumference of the concrete pole 9 comprising reinforced concrete. The reinforcing layer 11 covers a depth of at least 30 cm and a height of at least 100 cm relative to the ground level upon burying of the concrete pole 9. Reinforcing fibers 4 of the reinforcing layer 11 are oriented in the axial direction of the reinforced concrete. The total cross-sectional area (S R) and modulus of elasticity (E R) of the reinforcing fibers 4 of the reinforcing layer 11 satisfy the following relational formula relative to the totalcross-sectional area (S s) and modulus of elasticity (E s) of the axial reinforcing bar of the reinforced concrete: 0.06 ~ E R - S R/E s ~ S s < 3.0
