Claims
- 1. Casting apparatus for a storage vault cover comprising:
- (a) a framework including a plurality of frame members secured to one another to define an aperture and wherein said framework is elevated from a plurality of legs;
- (b) form means for forming a pour cavity from a plurality of form sections, wherein ones of said form sections include portions which define a bottom of the pour cavity and wherein the bottom includes an aperture for receiving a storage tank which projects into the pour cavity; and
- (c) means for securing said form sections to said framework and to one another, whereby a cover is cast in place to a storage tank which is positioned to extend into said pour cavity and which cover is mountable to a separately cast storage vault.
- 2. Apparatus as set forth in claim 1 including means for slidably supporting ones of said form sections to said framework.
- 3. Apparatus as set forth in claim 2 wherein the slide support means includes a plurality of couplers secured to said framework and a plurality of support members which project from said couplers.
- 4. Apparatus as set forth in claim 1 wherein said framework includes first and second spacers, which spacers abut said bottom defining portions of the form sections.
- 5. Apparatus as set forth in claim 1 wherein the bottom defining portions of said form sections include vertically offset planar portions, whereby ledges are cast into the cover to align with vertical sidewalls of a base vault which receives the cast cover.
- 6. Apparatus as set forth in claim 5 wherein ones of said form sections include rail portions which define chamfered edges into said cover.
- 7. Apparatus as set forth in claim 1 wherein said framework includes means for slidably supporting ones of said form sections to said framework, wherein the bottom defining portions of said form sections include vertically offset planar portions and wherein said framework includes first and second spacers which abut the bottom defining portions of the form sections whereby ledges are cast into the cover to align to vertical sidewalls of the storage vault which receives the cast cover and tank.
- 8. Apparatus as set forth in claim 1 including means for varying the length of each of said legs.
- 9. Casting apparatus for a storage vault comprising:
- (a) a framework including a plurality of frame members secured to one another to define an aperture, wherein said framework is elevated from a plurality of legs;
- (b) form means for forming a pour cavity between a plurality of form sections, wherein ones of said form sections are supported from a plurality of supports which extend from said framework, wherein said form sections include chamfer forming rail portions, wherein ones of said form sections include bottom pieces having first and second coplanar portions which mate with first and second spacers at said framework to define a bottom of the pour cavity and an aperture through said bottom; and
- (c) means for securing said form sections to said framework and to one another, whereby a cover is cast in place to a storage tank which is positioned to extend into the pour cavity at the aperture through said bottom and which cover and tank mount in alignment to a separately cast storage vault.
- 10. Casting apparatus for a storage vault cover comprising:
- (a) form means for forming a pour cavity from a plurality of form sections which are secured to one another, wherein ones of said form sections include portions which define top and bottom walls of the cover, and wherein the bottom wall defining portions form an aperture for receiving a storage tank which projects into the pour cavity; and
- (b) frame means for securing said form sections about the storage tank, whereby a cover is cast in place to the storage tank and which cover and tank are mountable to a separately cast storage vault.
- 11. Apparatus as set forth in claim 10 wherein said frame means comprises a plurality of frame members secured to one another and elevated from a plurality of legs to define an aperture whereat said form sections are mounted.
- 12. Apparatus as set forth in claim 11 including support means for moveably supporting ones of said form sections to said frame means, whereby the form sections can be brought into and out of abutment to the storage tank.
- 13. Apparatus as set forth in claim 12 wherein the support means includes a plurality of couplers secured to said frame members and a plurality of support members which mount to said form sections and to said couplers.
- 14. Apparatus as set forth in claim 11 including means for varying the length of each of said legs.
- 15. Apparatus as set forth in claim 10 wherein the bottom defining portions of said form sections include vertically offset planar portions, whereby ledges are cast into the cover to align with vertical sidewalls of a base vault which receives the cast cover.
