Abstract
An elongate sleeve tie is used with casting form ties in the manufacture of composite wall structures. The casting form ties and sleeve ties act to secure one or more casting forms in a rigid position relative to an insulating layer positioned between the casting forms during the manufacture of composite wall structures. The casting form tie is received in a central recess of the elongate sleeve tie. Once the composite wall has been formed, the casting form ties may be pulled out of the wall, leaving the elongate sleeve ties in place. Removal of the casting form ties eliminates the thermal bridges that metal casting form ties would otherwise create. At least a portion of the sleeve tie is formed of a material having a high thermal resistance.
Claims23
An elongate sleeve tie designed to receive a casting form tie for use in manufacturing a composite wall structure comprising an insulating layer sandwiched between first and second structural layers, the elongate sleeve tie comprising an elongate sleeve body formed from a material having high thermal resistance, said elongate sleeve body comprising:
- a mesial segment positionable through a passage within an insulating layer when the insulating layer is in a desired spaced-apart relationship between two casting forms used to manufacture a composite wall structure;
- a first anchor segment adjacent to a first side of the mesial segment and positionable within a first space between the insulating layer and a first casting form for placement of a first layer of a hardenable structural material within the first space during manufacture of a composite wall structure;
- a second anchor segment adjacent to a second side of the mesial segment and positionable within a second space between the insulating layer and a second casting form for placement of a second layer of a hardenable structural material within the second space during manufacture of a composite wall structure,
- wherein at least one of said first and second anchor segments further comprises means for anchoring said elongate sleeve tie within a hardened layer of structural material;
- and
- a central recess configured to receive therein a casting form tie used to connect first and second casting forms together during manufacture of a composite wall structure.
An elongate tie portion comprising:
- an elongate tie half body formed from a material having high thermal resistance,
- said elongate tie half body comprising a trough and at least one of a mating recess or protrusion configured to mate with a corresponding mating recess or protrusion in another tie half body in order to releasably join two tie half bodies together to form an elongate sleeve body of an elongate sleeve tie for use in manufacturing a composite wall structure including an insulating layer sandwiched between first and second structural layers, the elongate sleeve body, when formed by joining two tie half bodies together, comprising:
- a mesial segment positionable through a passage within an insulating layer when the insulating layer is in a desired spaced-apart relationship between two casting forms used to manufacture a composite wall structure;
- a first anchor segment adjacent to a first side of the mesial segment and positionable within a first space between the insulating layer and a first casting form for placement of a first layer of a hardenable structural material within the first space during manufacture of a composite wall structure;
- a second anchor segment adjacent to a second side of the mesial segment and positionable within a second space between the insulating layer and a second casting form for placement of a second layer of a hardenable structural material within the second space during manufacture of a composite wall structure;
- and
- a central recess configured to receive therein a casting form tie used to connect first and second casting forms together during manufacture of a composite wall structure.
A method of manufacturing a composite wall structure, comprising:
- erecting a first casting form;
- inserting a plurality of casting form ties through corresponding holes in said first casting form and locking a first end of each casting form tie to said first casting form;
- placing a plurality of elongate sleeve ties over each of said casting form ties, each elongate sleeve tie comprising an elongate sleeve body formed from a material having high thermal resistance, said elongate sleeve body comprising:
- a mesial segment positionable through a passage within an insulating layer when the insulating layer is in a desired spaced-apart relationship between two casting forms used to manufacture a composite wall structure;
- a first anchor segment adjacent to a first side of the mesial segment and positionable within a first space between the insulating layer and a first casting form for placement of a first layer of a hardenable structural material within the first space during manufacture of a composite wall structure;
- a second anchor segment adjacent to a second side of the mesial segment and positionable within a second space between the insulating layer and a second casting form for placement of a second layer of a hardenable structural material within the second space during manufacture of a composite wall structure;
- and
- a central recess configured to receive therein a casting form tie used to connect first and second casting forms together during manufacture of a composite wall structure:
- positing an insulating layer in a spaced-apart relationship relative to said first casting form so that said mesial segment of each elongate sleeve body is positioned at least partially within said insulating layer, so that a first space exists between said first casting form and said insulating layer, and so that said first anchor segment of each elongate sleeve body is positioned at least partially within said first space;
- erecting a second casting form in a spaced-apart relationship relative to said insulating layer and locking a second end of each casting form tie to said second casting form so that a second space exists between said second casting form and said insulating layer and so that said second anchor segment of each elongate sleeve body is positioned at least partially within said second space;
- introducing unhardened structural material into said first and second spaces;
- allowing the unhardened structural material to harden in order to form a composite wall structure;
- removing the said casting forms from the composite wall structure;
- and
- removing the casting form ties from the composite wall structure.
