PURPOSE: A strand for tension with an improved watertight structure and an inner lower body assembly using the same are provided to maximize waterproofing and anti-corrosion properties by completely blocking a grouting agent or moisture. CONSTITUTION: A strand(100) for tension with an improved watertight structure comprises a strand member(110), an outer stiffener(122), an inner stiffener(124), a cap-shaped seal member(130), and a ring-shaped seal member(140). The strand member is composed of a core member(112) and a coating member(114). The outer stiffener covers the end of the coating member and the front end of the core member. The inner stiffener is inserted between the front end of the core member and the outer stiffener. The cap-shaped seal member seals the core member. The ring-shaped seal member is adhered to the rear end of the outer stiffener. |
