A tie system is provided for use with a wall form for a cementitious backup wall and for use with a wall tie to connect between the cementitious backup wall and a veneer. The tie system includes a backup wall connector and a form connector. The form connector is connectable to the form and secures the backup wall connector in position as the wall form is filled. The connector may have heat transfer reducing perforations. The connector may have an outwardly positioned flange to which external wall members may be attached. The connector may have multiple gap-setting features.

The tie apparatus of claim 1 wherein said second portion has a lengthwise extent between said first portion and said third portion corresponding to an insulation thickness. 3. The tie apparatus of claim 1 wherein said first portion and said second portion are substantially co-planar, said third portion includes a web region, said web region being substantially co-planar with said second portion, said indexing fittings including a plurality of apertures passing through said web region, said plurality of apertures including said first aperture, and said flange of said third portion is oriented out-of-plane relative to said web region; said plurality of apertures of said web region present seats in which to introduce either of a brick tie and a form connector, and said flange presents a surface against which to fasten veneer. 4. The tie apparatus according to claim 3 wherein said array of indexing fittings includes at least a first set of indexing members offset away from said flange toward said second portion, and a second set of indexing members offset away from said flange toward said second portion, said first set of indexing members being more offset away from said flange than is said second set of indexing members. 5. The tie apparatus of claim 1 wherein said array of indexing fittings includes at least a first set of indexing members offset from said. flange and a second set of indexing members offset from said flange, said first set of indexing members being more offset from said flange than is said second set of indexing members. 6. The tie apparatus of claim 1 wherein said anchor fitting includes a first aperture and said first aperture has a closed circular periphery. 7. The tie apparatus of claim 6 wherein said first portion and said second portion are substantially co-planar, said third portion includes a web region, said web region being substantially coplanar with said second portion, said indexing fittings including a plurality of apertures passing through said web region, said plurality of apertures including a second aperture, said second aperture having a smaller diameter than said first aperture. 8. A tie system for use with a penetrable form for a cementitious backup wall, the tie system comprising: (a) a form connector connectable to a form;(b) a backup wall connector that has a first portion that includes a first end that fits through an aperture in the form, and that has a first aperture formed in said first end to admit cementitions material therethrough said first aperture defining an embedment anchor to be held in the cementitious material, the backup wall connector having a second end having an outward margin that is most distant from said said first end;(c) said backup wall connector has a second portion connected to said first portion, and a third, portion connected to said second portion, said second portion being between said first portion and said third portion;(d) said third portion of the backup wall connector having an array of seats, said array of seats defining a selection of form connector accommodations distant from said first portion, and said form connector being selectively seatable therein;(e) the selection of accommodations in said backup wall, connector also defining brick tie engagement fittings, said brick tie engagement fittings being smaller than said first aperture, said brick tie engagement fittings including ones thereof located at a selection of distances from said outward margin, and at a selection of heights at each distance of said selection of distances;(f) said second portion having perforations therein, said perforations of said second portion being smaller than said first aperture; and(g) said form connector being removable; and(h) there are two said form connectors, and said array of seats defines accommodations in which to receive said two form connectors, and when, so received said seats prevent forward and rearward relative movement between the form connectors and the backup wall connector. 9. The tie system or claim 8 wherein said second portion is predominantly perforate. 10. The tie system of claim 8 wherein said second portion is more predominantly perforate than is said first portion. 11. The tie system of claim 8 wherein: said first portion and said, second portion are substantially co-planar;said third portion includes a web region and a flange mounted to said web region distant from said second, portion;said web region being substantially co-planar with said first portion and said second portion, and including said indexing fittings; andsaid flange extending out-of-plane cross-wise to said web region. 12. A tie system as claimed in claim 8 wherein: said third portion includes a web region and a flange mounted to said web region distant from said second porton;said flange extends in a plane substantially perpendicular to said first and second portions, said flange presenting an attachment surface to which the veneer can be mechanically fastened. 13. A tie system as claimed in claim 8, wherein said array of seats defines accommodations in which to receive said form connectors and a brick tie at the same time. 14. A tie system as claimed in claim 8, wherein: the backup wall connector has a first portion defining an embedment anchor to beheld in the cementitious material, said embedment anchor including said first aperture;the backup wall connector has a second portion adjoining said first portion, said second portion being perforated to reduce heat transfer therealong; andthe backup wall connector has a third portion, said third portion including said array of seats. 15. A tie system as claimed in claim 8 wherein said backup wall connector has a flange at said outward margin, said flange defining an alternate interface at which mechanically to fasten a veneer. 16. The tie system of claim 8 wherein said first aperture has a closed circular periphery. 17. A tie system as claimed in claim 14 wherein said backup wall connector has a flange at said outward margin, said flange defining an alternate interface at which mechanically to fasten a veneer. 18. The tie system of claim 8 in combination with a form for the cementitious backup wall, said third portion of said backup wall connector includes a bent flange defining a short leg of said backup wall connector, the form having an inside and an outside; said tie system being mounted to said form, and when so mounted, said long leg first and second portions extending through said form and said short leg of said backup wall connector being located outwardly of said form.
