PROBLEM TO BE SOLVED: To prevent shear fracture and the separation of concrete and a steel material from each other from being caused by an excessive load, without causing heat distortion. SOLUTION: In this composite segment 1, an outside frame body part 9 with an almost L-shaped cross section, which forms corners on four sides of an arc-shaped plate-like outer peripheral surface, and an inside frame body part 10, constitutionally identical to the frame body part 9, are arranged in an opposed manner. Upper and lower flanges 11a and 11b of an lattice 11 with an I-shaped cross section are each connected to plates 9b and 10b of both frame body parts. A bolt 13 is screwed as a dowel into the female screw parts of the respective flanges 11a and 11b of the lattice 11. Since connected in an unheated state, the bolt 13 adheres to the concrete 3 with high adhesion strength without causing welding distortion. COPYRIGHT: (C)2006,JPO&NCIPI
