Abstract:
A foam block concrete form having ton and bottom longitudinal edges comprising:a pair of opposing foam panels spaced parallel from each other, each panel having at least one substantially planar rectangular segment having a horizontal pair of opposing longitudinal edges, a vertical pair of longitudinal edges, and inner and outer surfaces; engaging means formed along the horizontal and vertical pairs of longitudinal edges associated with each panel for removably engaging one block form with other block forms having similar and complimentary engaging means associated therewith when placed both side-by-side and vertically adjacent thereto; the engaging means associated with the horizontal pair of opposing longitudinal edges of each panel including two rows of alternating teeth and sockets along each edge, one row being offset from the other row by the distance of one side of one tooth, the teeth associated with one of the opposed horizontal longitudinal edges being vertically aligned with the sockets associated with the other of the opposed horizontal longitudinal edges and the sockets associated with one of the opposed horizontal longitudinal edges being vertically aligned with the teeth associated with the other of the opposed horizontal longitudinal edges; said pair of opposing panels forming said block form being disposed relative to each other such that the teeth associated with the row of alternating teeth and sockets located adjacent the outer surface of one of said pair of panels are horizontally aligned with the sockets associated with the row of alternating teeth and sockets located adjacent the outer surface of the other of said pair of panels, and the teeth associated with the row of alternating teeth and sockets located adjacent the inner surface of one of said pair of panels are horizontally aligned with the sockets associated with the row of alternating teeth and sockets located adjacent the inner surface of the other of said pair of panels; and a plurality of substantially planar ties positioned transverse to and between the pair of opposing foam panels, each tie including a web portion separating a pair of opposed flange members encapsulated within respective opposing foam panels along a respective lateral panel axis; said engaging means enabling one of said block forms to be engaged with a plurality of similarly constructed block forms in both a side-by-side arrangement and a vertically stacked arrangement regardless of the orientation of said block forms the top longitudinal edges of one block form being engageable with both the top and bottom longitudinal edges of another similarly constructed block form and the bottom longitudinal edges of one block form being engageable with both the top and bottom longitudinal edges of another similarly constructed block form.
