SEGMENT CONNECTION PART STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a connection part structure that can simplify specifications for welding between a main beam and a joint plate of a segment. SOLUTION: The connection part structure is for a segment 1 in which a steel shell 5 comprising main beams 2, joint plates 3 and a skin plate 4 is filled with concrete 6. Joint fittings 7 with a bolt hole 7a are fixed at fillet welds 7b to an inner side of a longitudinal end of the main beams 2. Segments 1 adjacent in a tunnel circumference direction are coupled with coupling bolts 8 passed through the joint fittings 7 and the joint plates 3. COPYRIGHT: (C)2004,JPO
