ABSTRACT:
Cast panels for building assembly and erection are formed and cured through the use of an apparatus which particularly facilitates high rates of production of such panels and thereby facilitates more economical building construction practices. Fluid materials being cast into panels are received within forms which comprise a cured concrete bed defining a horizontal planar surface maintained at an elevated temperature. Following curing of the fluid materials cast into the forms, stripping of the panels from the form is facilitated by vertically movable side forming members and by bulkheads separating the cured materials into predetermined panel lengths.
