Prestressed concrete structure, reinforcing member used for the prestressed concrete molded articles, and sheet member used for the reinforcing member

摘要

A prestressed concrete structure comprising an elongated concrete molded article having a pair of side surfaces opposed to each other, a plurality of tensile members laterally extending through the concrete molded article to be secured at each end to the side surfaces of the concrete molded article in a tensioned state and imparting a compressive load to the concrete molded article, side guards arranged along both side surfaces of the concrete molded article so as to cover the ends of the tensile members, and reinforcing members arranged on the side surfaces of the side guards in order to prevent the broken tensile members from protruding beyond the side surfaces thereof breaking through the side guards when the tensile members in the tensioned state are broken. The reinforcing members stretch little in the longitudinal direction but easily stretch in the transverse direction on the side surfaces of the side guards, and when pushed from the inside by the ends of the tensile members that protrude as a result of breakage, the peeling of the reinforcing members spreads out in the longitudinal direction of the concrete molded article on the side surfaces of the side guards but spreads out little in the transverse direction.
