摘要： PROBLEM TO BE SOLVED: To provide a steel concrete composite underground wall for thinning the wall thickness by using an inexpensive steel material.
SOLUTION: This steel concrete composite underground wall uses wide-flange shape steel with an inner rib composed of concrete and the wide-flange shape steel with the inner rib installed by welding a deformed reinforcement in the longitudinal direction to a flange inside surface of the wide-flange shape steel. The adjacent wide-flange shape steel with the inner rib is separately erected on the ground in the wall longitudinal direction so that a flange outside surface of the wide-flange shape steel with the inner rib is opposite to a wall surface. These concrete and wide-flange shape steel with the inner rib are integrated by connecting the concrete outside of a position of the flange inside surface of the wide-flange shape steel with the inner rib and the concrete inside of a position of the flange inside surface of the wide-flange shape steel with the inner rib, and the concrete sandwiched by the flange inside surface of the wide-flange shape steel with the inner rib also sticks to the respective wide-flange shape steel with the inner rib via the deformed reinforcement.
