Supplementary reinforcing construction for a reinforced concrete pier

Abstract

A supplemental reinforcing structure for supplementally reinforcing an existing reinforced concrete pier and a reinforced concrete pier reinforcing method facilitating and simplifying field work, and capable of saving time and labor necessary for field work and of improving the quality and reliability of field work. A closed steel plate structure is constructed so as to surround a reinforced concrete pier with a space formed between the closed steel plate structure by connecting a plurality of steel elements including flat steel elements (6) having longitudinal mating edge portions (5) for forming mechanical joints and angular steel elements (7) having longitudinal mating edge portions (5) for forming mechanical joints and a shape resembling an angle iron. The mating edge portions (5) of the adjacent steel plates (6, 7) are joined together to connect the adjacent steel plates (6, 7). A freely formable hardening material is filled in the space and is made to harden therein. Since the steel elements (6, 7) are firmly connected together by mechanically joining together the adjacent mating edge portions (5) without requiring welding, field work is facilitated and simplified, and the steel elements may be made of a corrosion-resistant metal or may be formed by processing surface-treated metal plates.
