ABSTRACT OF THE DISCLOSURE This invention relates to a quickly assembled prefabricated metal concrete pouring form for slabs and the like that remains in place as an in integral part of the finished structure. The basic elements of the structure are exterior wall sections with each containing a series of vertically-aligned pairs of slots arranged in parallel horizontal rows throughout the length thereof and which can be telescoped into overlapping relation to place selected pairs of these slots in registry with one another to receive the hook-forming elements of one or more types of connectors that lock the sections together in freestanding assembled condition. Two of these connectors, namely, a ground stake and a detachable endpiece of a spreader subassembly both include a vertically- spaced pair of downturned hook-forming elements to effect the locking action while the corner sections employ horizontally-spaced pairs of horizontally-disposed tongues for this same purpose each spreader sub- assembly includes a spacer formed of sheet metal folded to provide a base and upstanding opposed walls defining a slot-like channel there- between. One of the sidewalls is internally dimpled at each end with these dimples being designed to enter apertures in an apertured extension of the endpiece so as to adjustably and detachably retain the latter in telescoped relation within the channel Partition walls structurally similar to the exterior wall sections are used between long spans separating the latter to produce a divider.
