ABSTRACT:
A readily assembled and readily stripped, reusable concrete form is constructed from a plurality of similar flat-faced panels having spaced, co-planar, open-ended edge-oriented slots in the margins of the other or opposite faces thereof; and a plurality of elongated L-shaped keys which are employed both to interlock the panels on each side of the form, and to interlock the form from side to side. The panels are arranged in two spaced, parallel, oppositely disposed, edge to edge, co-planar flat-faced arrays of the same; and are interlocked with one another in each array by placing a first set of the keys in the plane of the slots opposite points relatively within the margins of the panels, and slidably engaging the keys in the adjacent slots of adjacent panels. The arrays are interlocked with one another by placing a second set of the keys in the plane of the slots opposite points relatively without the margins of the panels, slidably engaging the latter keys in the slots of the panels along corresponding edges of the arrays, and interconnecting the latter keys with one another transversely of the space between the arrays.
