Abstract

A component (20, 22) and method for a casting process, typically for cold-process casting of concrete wall, floor, ceiling or other panels or element in situ in building construction, leaving embedded in the cast panel a fastening surface (24) which can be adjustable to allow correction of non-uniform cast surfaces. The component may be integrated to conventional form-tie systems which use ties to space removable/reusable forms, holding forms a set distance apart, and can also hold a barrier material (typically expanded foam insulation) against the inner surface of a form(s) while casting is underway; when the forms are removed, leaving a component embedded providing an adjustable surface suitable for attaching material such finishing sheet material. The component can allow adjustment of its mounting surface with respect to the cast surface and to other like components in the cast panel to provide for (substantially) uniform surface for mounting finishing materials and/or fixtures.

Claims

1. An apparatus for use with cast or other construction elements comprising:

a. a body shaped with a generally flat outer face, with sufficient thickness to allow piercing by screw or nail or staple fasteners with a narrower inner part extending inward from the inner side of said outer face, said narrow inner part made to be cast or embedded into a panel or other construction element;

b. Said inner part comprising one or more sub-components which provide means of being adjusted in a direction perpendicular to the surface of the construction element within which it has been cast or embedded.

2. An apparatus as in claim 1, where the thickness provided in said outer face to permit piercing by fastening means is provided by placement behind said outer face and around said inner part of a spacer to accept said fastening means, and to avoid filling the space required to utilize said fastening means with the substance of the construction element or material being used to cast or form said apparatus within said element.

3. The apparatus in claim 1, shaped and constructed of a material or with suitable friction-relieving coating upon said inner part, such that when said apparatus is cast within a cast or formed material of said construction element, the outer surface of the said narrow inner part of the apparatus causes the formed material to assume a shape which, in interaction with the said narrow inner part so coated provides the said means of adjustment.

4. The apparatus in claim 3 where the said inner part is formed on its outer surface of a male thread and the formed material once cast and hardened forms a mating female thread.

5. The apparatus in claim 3 where the said adjusting means is provided by a frictional fit formed of adjacent ring-shaped outer protuberances along the shaft of the said narrow part, which protuberances are made to compress enough to allow tightly fitted but moveable engagement with matching ring-shaped detents formed within the female void formed during casting by the shape of the said apparatus'"'"' narrow part.

6. The apparatus in claim 1 where said inner part'"'"'s adjustment means comprises two sub-parts, an outer sub-part which is cast and held within the construction element, and an inner subpart which is permanently fixed to said outer face, and which is adjustable within the said outer sub-part in a direction (essentially) perpendicularly to the face of the formed surface within which the entire body and notably the outer sub-part is cast or embedded.

7. The apparatus in claim 1 where said outer face has shape and characteristics suitable for a purpose other than fastening, such as a hanger, bolster, prop, hook, stand, or receptacle.

8. The apparatus in claim 1 where said outer facets to hold a barrier next to the inner surface of a form used in the casting of panels or other construction elements.

9. The apparatus in claim 8, having a void within itself extending essentially linearly through its body about a central line perpendicular to the surface of the element within which it is cast or embedded, suitable to surround a form tie of conventional design and constructed to perform the same function as a conventional form tie in addition to its other inherent functions.

10. The apparatus of claim 9, said inner void being shaped to include means to be affixed to a conventional form tie and to thus form part of the temporary form structure, holding said apparatus against the inner surface of said form and assisting to hold said form to a proper distance along said form-tie such that the void formed by the said form and tie system is of desired configuration.

11. The apparatus of claim 9, acting in horizontal panel forming operations as a bolster or shim to hold reinforcing material such as re-bar and/or conduit such as for electrical, communications, plumbing, control and/or other lines fixed in a desired location within the volume to be formed by casting in said forming operations.

12. The apparatus of claim 11, as well being capable of receiving means of lifting and/or manipulating the thing (such as a tilt-up cast panel) within which it is cast or embedded in said forming operation.

13. The apparatus of claim 1 and claim 6, being capable of having affixed to its outer part a hangar, rod, or other device from which ceilings, fixtures, or other finishing or construction elements may be hung using said adjustment means.

14. The apparatus of claim 1 and claim 6, used by being inserted within a foam or masonry stack element prior to or during the assembly of that unit into a wall or other panel or construction element by masonry or casting or forming or combination methods.

15. A method of casting panels or other construction elements using conventional forms with the apparatus provided herein, where the panel is a ceiling, floor, wall, or divider.

16. A method of preparing a construction element such as a cast surface, for accepting a finishing material or covering to be mounted on the apparatus, once retrofitted.

17. A method of pouring a tilt-cast panel with conduit and structural reinforcement in place, located and held using the apparatus provided herein.

18. A method of providing hangars from the lower surface of a cast combined floor and ceiling in large-scale cast-in-place construction.
