ANCHORAGE ZONE STRUCTURE OF PRESTRESSED CONCRETE STRUCTURE
To suppress an anchorage zone of a prestressed concrete structure from corroding or decreasing in durability.SOLUTION: A water drain passage 12 is formed on a material which is hard to corrode such that one end (upper end) communicates with a recessed part 4 formed in a concrete plate 2 and the other end (lower end) is open to outside the concrete plate 2, and the passage 12 is inclined downward from the one end to the other end. Consequently, water entering the recessed part 4 is discharged to the outside through the passage 12.SELECTED DRAWING: Figure 2
【課題】プレストレスコンクリート構造物における定着部での腐食や耐久性の低下を抑制できるようにする。【解決手段】コンクリート板２に形成された凹部４に、一端（上端）が連通し他端（下端）がコンクリート板２の外部に開口するように、腐食しにくい材質から成る水抜き用通路１２を形成し、この通路１２を一端から他端に向かって下向きに傾斜させる。これにより、通路１２を介して、凹部４内に浸入した水分を外部に排出する。【選択図】図２
