Patent ID: 8646239

Claim:
A device comprising: a first wall, said first wall including a first lateral support disposed lengthwise on a first surface and a second lateral support disposed lengthwise on a second surface, wherein said first lateral support of said first wall includes an extended portion, and said second lateral support of said first wall includes a recess, said first wall including at least one channel extending from the first surface to the second surface; a second wall, said second wall including a first lateral support disposed lengthwise on a first surface and a second lateral support disposed lengthwise on a second surface, wherein said first lateral support of said second wall includes an extended portion, and said second lateral support of said second wall includes a recess, said second wall including at least one channel extending from the first surface to the second surface; a course disposed between and coupled to said first wall and said second wall, said course characterized by one or more turns, wherein a first length of said course is disposed between the first and second wall at a 45 degree angle and a second length is disposed from said first length at a 90 degree angle; at least one end condition, said end condition including a partial-height element disposed along said course, whereby said partial-height element is matchable with an inverse thereof; a reinforcing assembly disposed inside said first wall, said course, and said second wall, wherein said reinforcing assembly includes: a plurality of wire mesh portions having one or more first portions disposed substantially in a planar manner along at least a part of said first wall and having one or more second portions disposed substantially in an undulating manner along at least a part of said course in a region where said course meets said first wall, interpenetrating to form one or more interlocks and disposed to define a void between said first portions and said second portions, said void defining an elongated space having an axis, said one or more interlocks disposed about the channels, capable of restraining a vertical element when positioned therebetween from movement in an XY plane substantially transverse from said axis, and capable of having their movement restrained in said XY plane by said vertical element when positioned therebetween, wherein the one or more interlocks provides structural support for the channels in response to compression between a straight part of at least one of said one or more first portions and a bent part of at least one of said one or more second portions.
