Title:
HAT-SHAPED STEEL SHEET PILING, STEEL SHEET PILING WALL, AND METHOD FOR MANUFACTURING STEEL SHEET PILING WALLS
Document Type and Number:
WIPO Patent Application WO/2020/045113
Kind Code:
A1
Abstract:
In a cross-section intersecting the longitudinal direction, a hat-shaped steel sheet piling comprises: a web extending in the width direction on a first side in the cross-sectional height direction; a pair of flanges extending from both ends of the web in the width direction toward both sides in the width direction and toward a second side in the cross-sectional height direction; a pair of arms each extending in the width direction from the ends of the pair of flanges on the second side in the cross-sectional height direction and toward both sides in the width direction; and a pair of fitting joints formed on each of the pair of arms at the end on the side opposite to the pair of flanges. The polar moment of inertia Ipo around the fitting center of one of the pair of fitting joints in the cross-section is larger than 8.0 × 105 cm4, and the length Bw of the web and the length Ba of one of the pair of arms in the width direction satisfy the relationship Ba/Bw > 0.2.
