Concrete pole and method of reinforcing same

摘要

A simple reinforcement for concrete pole improving the elasticity of the pole is provided. A reinforcing layer of a fiber-reinforced composite material is applied to a portion of the outer circumference of the concrete pole 9 that comprises 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 when the concrete pole 9 is placed in the ground. Reinforcing fibers 4 of the reinforcing layer 11 are oriented in the axial direction of the reinforced concrete. The total cross-sectional area (SR) and modulus of elasticity (ER) of the reinforcing fibers 4 of the reinforcing layer 11 satisfy the following relational formula relative to the total cross-sectional area (SS) and modulus of elasticity (ES) of the axial reinforcing bar of the reinforced concrete:0.06<ERxSR/ESxSS<3.0.
