Abstract
A method and apparatus for vertically molding concrete slabs in which a tilted semi-cubical enclosure is provided containing a plurality of plates spacedly positioned from one another such that a cavity is formed between plates in which the slabs are formed. The tilt of the enclosure maintains the plates and spacers in their desired positions during loading and unloading of the enclosure. Within one aspect of this invention the spaced plates are insulation plates having fasteners projecting therefrom into cavities such that when concrete is poured into and permitted to harden in the cavities, the insulation plates will be laminated to the concrete.
Claims18
A battery mold for substantially vertically molding of concrete slabs comprising:
- (a) a battery enclosure including a unitary box having a bottom wall, two sidewalls and an end wall, said entire enclosure being tilted so as to tilt the bottom wall a slight angle to the horizontal and the end wall a slight angle from the vertical with the sidewalls arranged vertically;
- (b) a plurality of separator plate means located within said unitary box each of which is parallel to the end wall and perpendicular to said bottom wall and said sidewalls, said plates extending between said sidewalls;
- (c) means for spacedly positioning each of said plate means for an adjacent plate means so that a cavity for concrete slab molding is formed therebetween and whereby said plate means are arranged at the same slight angle of tilt as said bottom and end walls, such angle of tilt being sufficient without any additional support to maintain said plates in said box before pouring of concrete therein;
- and
- (d) means for biasing the plates toward said end wall after said separate plate means are in place ready for pouring of concrete.
A method of molding concrete slabs comprising:
- (a) providing a unitary battery box with two sidewalls, a bottom wall perpendicular to and extending between said sidewalls and an end wall perpendicular to said sidewalls and bottom wall and extending between said sidewalls;
- (b) arranging said battery box at a slight tilted angle whereby said end wall is tilted at a slight angle from the vertical and said bottom is tilted at the same said slight angle from the horizontal with said sidewalls being vertical;
- (c) spacedly positioning one at a time a plurality of separator plates from one another within said unitary battery box so that a cavity is formed between adjacent plates, and such that said plates are substantially perpendicular to and extend between said two sidewalls and are substantially parallel to said end wall whereby said plates are each tilted and the angle of tilt is the same as said tilted angle of said bottom and end walls, such angle of tilt being slight but sufficient without any additional support to maintain said plates in said box before pouring of concrete therein;
- (d) applying a force to the separator plate furthest removed from said end wall thereby holding all of said separator plates in place within said unitary battery box in spaced position;
- and
- (e) pouring concrete into the cavities between said plates.
