Z-shaped sheet piling
View Patent ↗A sheet piling ( 15 ) comprising a first flange ( 16 ), a second flange ( 18 ), a web ( 19 ), a junction ( 20 ) between the first flange and the web, the junction having a substantially concave inner surface ( 44 ), the inner surface comprising at least a first concave surface of first radius ( 23 a ) and a second concave surface of second radius ( 23 b ). The inner surface may further comprise a third concave surface of third radius ( 23 c ).
1. A sheet piling comprising;
a first flange;
a second flange;
a web;
a junction between said first flange and said web;
said junction having a substantially concave inner surface;
said inner surface comprising at least a first concave surface of a first radius, a second concave surface of a second radius and a third concave surface of a third radius; and
said second radius being different from said first radius.
2. The sheet piling of claim 1 , wherein said third radius is different from said first radius.
3. The sheet piling of claim 2 , wherein said third radius is different from said second radius.
4. The sheet piling of claim 1 , wherein said third radius is substantially the same as said first radius.
5. The sheet piling of claim 4 , wherein said second concave surface is between said first concave surface and said third concave surface.
