Title:
STEEL SHEET PILING
Document Type and Number:
WIPO Patent Application WO/2012/098634
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide steel sheet piling that enables materials to be reduced without a female joint portion and a male joint portion separating. The steel sheet piling according to the present invention is provided with flange portions on both sides of the main body portion that project out from the front side to the rear side, wherein the male joint portion is formed on a free end of one of the flange portions being the first flange portion, and the female joint portion is formed on a free end of an other of the flange portions being the second flange portion. The male joint portion is bent back toward the rear side in a U-shape, when viewed from the side, from the free end of the first flange portion, and the female joint portion is bent back toward the front side in a U-shape, when viewed from the side, from the rear side of an extending portion that projects out from the free end of the second flange portion to the rear side. Inclining the end portions of both joint portions of such steel sheet piling into the respective U-shapes, and providing a projecting portion for abutting against the female joint portion of other steel sheet piling on the first flange portion, thereby brings the curved portions of both interlocked joint portions together and enables the width of the sheet-like materials constituting each of the joint portions to be reduced.
