摘要

PROBLEM TO BE SOLVED: To efficiently perform an upper part recovery operation for an H-steel positioned on the underground upper side by an easy and simple operation. SOLUTION: This wall member 1 for a continuous underground wall includes a connection fitting 6 which is disposed between the upper and lower ends at which a lower stage H-steel 3 and an upper stage H-steel 4 are made to abut on each other and a joint which is connected through a mounting bar operated from the mounting holes 10 formed in one flanges of the H-steels toward the mounting holes 10 formed in the other flanges and which is provided along the ends of the flanges of the H-steels. The H-steels disposed adjacent to each other are connected to each other through the joint. The connection fitting 6 includes an insertion part 6a which is made of a steel of such a size that can be disposed in a recess 3c or 4c which is divided by both flanges and web of the H-steel and disposed in the recess at one end in the state of being fixed to the recess at the other end among the upper and lower ends and an insertion hole 8 which is provided to the insertion part and allows the mounting bar to extend therethrough and which matches the mounting hole 10 formed in both flanges which partition the recess at the other end.
