APPAREIL DE REMISE SOUS TENSION D'UNE STRUCTURE PRECONTRAINTE

摘要

An apparatus for retensing a pre-stress structure. The apparatus includes a tensing apparatus installed at a rear portion of a precast strand support fixing member exposed from both ends of a prestress structure such as a precast beam for repeatedly tensing a precast strand having a stress loss. A checking member provided at the retensing apparatus for visually checking a stress loss in the tensed precast strand for thereby implementing an easier tensing of a reinforcing strand which is needed when fabricating a prestress structure and retensing an internal reinforcing strand even when a prestress loss occurs for thereby repeatedly retensing a deformed prestress structure.
