STEEL FRAMED REINFORCEMENT UNIT USED FOR CONTINUOUS UNDERGROUND WALL AND CONTINUOUS UNDERGROUND WALL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a steel framed reinforcement unit used for a continuous underground wall and the continuous underground wall using it for reducing its weight comparatively and sufficiently securing adhesion to concrete. SOLUTION: This steel framed reinforcement unit 1 is constructed of four H-steels 2 arranged in line longitudinally while setting their both side flange parts 2a toward both side wall faces of a continuous wall excavated groove A, vertical reinforcements 3a arranged side by side in the vertical direction while brought into contact with the flange parts 2a of the respective H-steels 2 to be fixed to the flange parts 2a by welding, horizontal reinforcement 3b, and reinforcing bars 4 arranged in the edge positions of the both flange parts 2a orthogonally to the vertical reinforcement 3a and the horizontal reinforcements 3b to be fixed to the vertical reinforcements 3a or the horizontal reinforcements 3b by welding. When the unit 1 is constituted in the executed groove filled with mud water and the mud water is replaced by concrete, the continuous underground wall with a reduced thickness is constructed.
