Claims
- 1. An inflatable form for use in building concrete type structures which comprises:
- an entirely enclosed closed end cylindrical balloon;
- straps of selected length which is less than the circumference of the cylindrical balloon, each strap having a center point;
- anchor means on each end of each said strap;
- a plurality of sleeve means attached to the form through which the straps extend for holding each said strap in a selected position along the wall of said cylindrical balloon such that when said balloon is inflated, each of said straps lies in a vertical plane which is parallel to the other vertical planes of the other straps and each said center lies in a straight line.
- 2. An inflatable form as defined in claim 1 in which there are a plurality of anchor positions on each said end of each said strap.
- 3. An inflatable form for use in building concrete structures comprising:
- an entirely enclosed inflatable closed end cylindrical form made of flexible material and having a longitudinal axis;
- a plurality of anchor straps located along the length of said form and fixed thereto, each strap being in a position such that each strap is in a plane perpendicular to said axis when said form is inflated.
- 4. An inflatable form as defined in claim 3 including a plurality of spaced anchors on at least one end of each said strap.
- 5. An inflatable form as defined in claim 3 including a plurality of spaced anchoring holes on at least one end of each said anchor straps.
- 6. An apparatus using an inflatable form for use in building concrete type structures on a foundation which comprises:
- an inflatable entirely closed end cylindrical form made of a flexible air impervious material;
- a plurality of anchoring straps in secured selected positions along the surface of said flexible material, each strap having a first end and a second end useful for anchoring.
- 7. An inflatable form as defined in claim 6 in which the length of each said strap is less than the circumference of said cylindrical form.
- 8. An inflatable form as defined in claim 7 in which the length of each strap is not over about one-half of the circumference of said cylindrical form.
- 9. An inflatable form as defined in claim 6 in which said straps are th in flexible steel straps and are fixed to the form.
- 10. An apparatus as defined in claim 6 including two spaced apart parallel anchor bars removably secured to said foundation, said bars having a plurality of spaced apart strap receiving slots.
- 11. An apparatus as defined in claim 6 including two spaced-apart parallel pipes secured to said foundation and spaced therefrom so that said strap may go under and wrap around said pipe.
- 12. An inflatable form for use in building concrete type structures which comprises:
- a closed end cylindrical balloon;
- anchor means on each end of said strap, each said anchor means having a plurality of anchor positions on each said end of each said strap;
- means to hold each said strap in a selected position along the wall of said cylindrical balloon such that when said balloon is inflated said straps are in a vertical plane which is parallel to the other planes of the other straps and each said center line lies in a straight line.
- 13. An inflatable form for use in building concrete structures comprising:
- an inflatable closed end cylindrical form made of flexible material and having a longitudinal axis;
- a plurality of anchor straps located along the length of said form and fixed thereto, each strap being in a position such that each strap defines a plane which is perpendicular to said axis when said form is inflated;
- a plurality of spaced anchoring holes on at least one end of each said anchoring strap.
- 14. An apparatus using an inflatable form for use in building concrete type structures on a foundation which comprises:
- an inflatable closed end cylindrical form made of a flexible air impervious material;
- a plurality of anchoring straps in secured selected positions along the surface of said flexible material, each strap having a first end and a second end useful for anchoring;
- two spaced apart parallel anchor bars removably secured to said foundation, said bars having a plurality of spaced apart strap receiving slots.
- 15. An apparatus used in an inflatable form for use in building concrete type structures on a foundation which comprises:
- an inflatable closed end cylindrical form made of a flexible air impervious material;
- a plurality of anchoring straps in secured selected positions along the surface of said flexible material, each strap having a first end and a second end useful for anchoring;
- two spaced apart parallel pipes secured to said foundation and spaced therefrom so that said strap goes under and wraps around said pipe and is secured back onto itself.
