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.
Claims5
An apparatus for forming and curing cast panels comprising:
- an elongate bed defining a horizontal planar surface for supporting material being cast,
- side form means for facilitating stripping of a cast panel and including a pair of stationary support means extending parallel and in spaced relation to said bed and a pair of slip form means engaging corresponding ones of said support means for movement vertically relative to said bed and said support means between a forming position wherein material cast between said slip form means is retained therebetween and an elevated release position wherein a cast panel may be stripped from said apparatus, and
- a plurality of bulkhead means disposed transversely between said side frame means for dividing material cast into said apparatus into a plurality of discrete panel lengths, each said bulkhead means being defined by a plurality of discrete plate members including a lower plate member, a pair of side plate members supported on said lower plate member and an upper plate member normally overlying said pair of side plate members, said plate members having stop means for normally arranging said plate members to define a hollow box structure, said stop means including inwardly directed lip portions of said side plate members and members extending vertically from said upper and lower plate members for engaging said lip portions and each of said side plate members being pivotally movable relative to the corresponding lower plate member upon removal of the corresponding upper plate member between an upright forming position whrein material being cast is retained and a tilted release position wherein a cast panel may be stripped from said apparatus.
