Abstract
An anchorage for gripping and fixing an end portion of a tendon is provided. The anchorage includes a base having a surface; and a coating film provided at least on a contact portion of the surface of the base. The contact portion contacts the tendon when the tendon is gripped by the anchorage. The coating film has an electrical resistivity of 104 Ω·m or more.
Claims11
An anchorage for gripping and fixing an end portion of a tendon, the anchorage comprising:
- a base having a surface;
- and
- a coating film provided only on a contact portion of the surface of the base to minimize corrosion between the tendon and the anchorage, the contact portion contacting the tendon when the tendon is gripped by the anchorage,
- wherein the coating film has an electrical resistivity of 104 Ω·m or more.
1 more element
A prestressed concrete (PC) structure comprising:
- a concrete structure;
- a tendon;
- and
- an anchorage configured to fix the tendon to the concrete structure, the anchorage being attached to an end portion of the tendon outside the concrete structure,
- the anchorage including
- a base having a surface, and
- a coating film provided only on a contact portion of the surface of the base to minimize corrosion between the tendon and the anchorage, the contact portion contacting the tendon in a state in which the tendon is gripped by the anchorage.
