1. A device for spacing a pair of adjacent sheets of insulating material from a concrete form sheet comprising:
- a pair of elongated caps having a U-shaped cross section, each adapted to be disposed on adjacent ends of a pair of sheets of insulating material;
a spacing member adapted to be disposed between sheets of insulating material and a form sheet, such spacing member having a threaded opening at each end;
a bracket disposed adjacent to said spacing member, said bracket having longitudinal opening therethrough and a pair of projecting outwardly tapered end portions adapted to engage said pair of elongated caps;
first means disposed through said elongated caps and the longitudinal opening of said bracket engaging said spacing member;
second means adapted to be disposed through a concrete form sheet for engaging said spacing member;
first means adapted to engage adjacent sheets of insulating material and coupled to said first means for engaging for tensioning said spacing member; and
second means adapted to abut on a concrete form sheet and coupled to said second means for engaging and for tensioning said spacing member.

Abstract
A method and apparatus is disclosed for forming insulated walls by pouring concrete directly on a form made in part of insulating material which will remain in place after the concrete sets. An apparatus for spacing the sheets of insulating material from the sheets of other material to create a concrete form is also disclosed, which also provides the function of bringing adjacent sheets of insulating material to create an adequate seal for the concrete. A tie holder for supporting cross members is also disclosed.

5. A concrete form and lock set comprising:
-
at least one form sheet; at least a pair of adjacent sheets of insulating material disposed parallel to and a predetermined distance from said at least one form sheet; at least a pair of metal caps having a U-shaped cross section, each one of said pair disposed on an end of a respective one of said sheets of insulating material whereby said metal caps are disposed adjacent to each other; a spacing member disposed between the sheets of insulating material and the form sheet, said spacing member having a threaded opening at each end; a bracket disposed adjacent to said spacing member, said bracket having a longitudinal opening therethrough and a pair of projecting outwardly tapering portions adopted to compress into the sheets of insulating material and engage said adjacent metal caps; and means coupled to the respective threaded openings on the spacing member for tensioning said spacing member while compressing said adjacent sheets of insulating material and form sheet whereby said bracket compresses into the sheets of insulation material and forces the adjacent caps together. - View Dependent Claims (6, 7, 8)
