Title:
鉄筋コンクリート構造物
Document Type and Number:
Japanese Patent JP6836476
Kind Code:
B2
Abstract:
To employ a mechanical anchorage method to an axial reinforcement by setting a surface of the axial reinforcement in a range in which a fracture surface of a cone-shaped fracture region reaches a surface of concrete as an unboned region, and to effectively prevent the occurrence of side-face exfoliation fracture at the concrete.SOLUTION: A reinforced concrete structure comprises concrete 21, and an axial reinforcement which is embedded into the concrete 21, and the axial reinforcement includes a mechanical anchorage member attached to its tip, and an unboned region 16 which is formed on a surface of a range having a prescribed length from the mechanical anchorage member. The prescribed length is a length in an axial direction up to a position in which a fracture face 22a of a cone-shaped fracture region 22 reaches a surface 21a of the concrete 21 which extends in parallel with the axial direction of the axial reinforcement.SELECTED DRAWING: Figure 4
