Title:
HAT-TYPE STEEL SHEET PILE
Document Type and Number:
WIPO Patent Application WO/2020/045119
Kind Code:
A1
Abstract:
This HAT-type steel sheet pile is provided with: a web extending in the width direction in a cross-section perpendicular to the longitudinal direction of the sheet pile; a pair of flanges which extend from respective end sections of the web in the width direction toward both sides in the width direction and form a flange angle θ with the width direction; a pair of arms which extend along the width direction from respective end sections of the pair of flanges, and extend toward both sides in the width direction; and a pair of fitting couplers formed in end sections on the opposite side of the pair of arms from the respective pair of flanges. The ratio of the total length of the web, the pair of flanges, and the pair of arms in the cross-section to the average plate thickness of the web, the pair of flanges, and the pair of arms is no less than 120. The effective width B and effective height h in the cross-section, and the flange angle θ satisfy the condition of the following equation (i) in which an integer C (1.01≤C≤1.13) is used within the range in which the thickness ratio of the flanges to the web is 0.6-1.0 inclusive, and the effective width B, the web length Bw in the cross-section, the cross-section height H, and the flange angle θ satisfy the relationship B-Bw-2H/tanθ>0.
