Abstract:
PROBLEM TO BE SOLVED: To assemble a plurality of kinds of segments such as plate segments and box-type segments with simple construction and, at the same time, to provide an erector device having no difference in holding height of the segments.
SOLUTION: An erector device 1a of a shield machine assembles selectively plate segments and box-type segments. In that case, a pair of bearing members 5a and 5b for mounting the plate segment holding claws 4a and 4b respectively to an erector main body are provided in an approachable, separable and movable manner, and when the bearing members are separated, a storage space for storing a holding unit for the box-type segments is formed between the bearing members 5a and 5b.
