Element based foam and concrete modular wall construction and method and apparatus therefor

A Pilaster Channel structure, for a beam and ledge in a wall structure of Blocks reinforced with concrete comprising:

• a pair of Channel members;
• said first Channel member having a substantially C-shaped cross-section comprising a vertical member and first and second horizontal members projecting substantially traversely away from said vertical member, said horizontal members connected to said vertical member at first and second positions which are a first distance apart;
• said second Channel member having (i) a vertical member, (ii) a horizontal member projecting away from a first position on said vertical member at a first angle substantially transverse to said vertical member, and (iii) a wall member projecting from a second position on said vertical member at a second angle greater than said first angle and ending in a third position, said first and second positions being a second distance apart which is less than the first distance;
• and
• a plurality of elongated ties, each tie having two ends, one end connected to the first Channel member, the other end connected to the second Channel member, said ties spaced from one another and fixing said Channel members relative to one another while defining an open space between the two Channel members, each tie including a slot configured to receive at least one Rebar in a position substantially transverse to said tie.

A Pilaster Channel structure for a wall structure of Blocks reinforced with concrete, comprising:

• two opposing, elongated Channel members, each having a base, an upper section and a lower section;
• and
• a plurality of ties securing the Channel members substantially parallel with one another with an open space therebetween;
• wherein a first distance between the upper sections of said Channel members is at least about one-and-one-half times a second distance between said lower sections of said Channel members, whereby the Pilaster Channel structure, when filled with concrete, is configured to create a ledge extending beyond the Blocks.

• and
• a plurality of ties securing the Channel members with the bases substantially parallel with one another, defining an open space between the Channel members;
• wherein a first distance of the open space between the upper sections of said Channel members is greater than a second distance of the open space between said lower sections of said Channel members, whereby the Pilaster Channel structure, when filled with concrete, is configured to create a ledge extending beyond the Blocks.
