DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anchored end structure for a tensile steel material that is not grouted with a binding agent over the entire length of the tensile steel material.

Generally, in cases where the material is not completely integrated with the structure by filling and solidifying grout such as cement mortar, such as suspension materials for cable-stayed bridges and tensile steel materials in prestressed concrete that enable the replacement of PC steel wires, , the tensile force of the tensile steel must be permanently maintained only by the anchoring structure at its end.

Conventionally, in such cases, a metal cylinder was permanently crimped over a long area of the end of the tensile steel material, and a screw was carved into it and secured with a nut. The structure requires a long time to manufacture and assemble, is expensive, and has poor stability, so a large safety factor must be taken into consideration.
