ATTACHMENT FOR JACKING OPERATION OF DENSELY PLACED PRESTRESSING TENDONS

摘要

PURPOSE: An attachment for jacking operation for a densely arranged prestressing tendon is provided to effectively jack multiple tendons even if the tendons are arranged densely. CONSTITUTION: An attachment for jacking operation for a densely arranged prestressing tendon comprises a tendon sleeve(100). One end of the tendon sleeve receives a wedge cone(12) therein. The tendon sleeve is installed between the end of a concrete structure(1) and a hydraulic jack(5). One end of the tendon sleeve has a support protrusion, and the other end thereof has a wedge cone insertion hole and a wedge hanging protrusion. The support protrusion is supported to the cross section of the hydraulic jack. The wedge cone insertion hole is connected to a tendon inlet hole. The wedge hanging protrusion is formed inside the wedge cone insertion hole and restricts the backward movement of a wedge.
