Abstract

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.

Claims (15)

1. A tie system for use with a penetrable wall form for a cementitious backup wall that is prepared from pourable cementitious material that is poured into the wall form and for use with a wall tie to connect between the cementitious backup wall and a veneer, the tie system comprising:

(a) a form connector;

(b) a tie connector; and,

(c) a longitudinally extending backup wall connector having first and second opposed longitudinally extending sides that are generally planar and being shaped to extend through an aperture in the wall form, and having a forward-facing form-connector engagement surface and a rearward-facing form-connector engagement surface that are positioned to directly engage the form connector to substantially prevent forward and rearward relative movement between the backup wall connector and the form connector.

2. A tie system as claimed in claim 1 , further comprising a forward-facing wall-tie-engagement surface and a rearward-facing wall-tie-engagement surface that are positioned to engage a wall tie to substantially prevent forward and rearward relative movement between the wall tie and the backup wall connector.

3. A tie system as claimed in claim 2 , wherein the forward-facing form-connector-engagement surface is the same as the forward-facing wall-tie-engagement surface, and wherein the rearward-facing form-connector-engagement surface is the same as the rearward-facing wall-tie-engagement surface.

4. A tie system as claimed in claim 2 , wherein the backup wall connector has a connector aperture defined by a connector aperture wall, wherein the connector aperture wall comprises the forward-facing and rearward-facing wall-tie-engagement surfaces.

5. A tie system as claimed in claim 1 , wherein the backup wall connector has at least one opening having a perimeter wall and defining at least one forward-facing backup-wall-engagement surface and at least one rearward-facing backup-wall-engagement surface.

6. A tie system as claimed in claim 1 , wherein the backup wall connector extends other than along a linear axis.

7. A tie system as claimed in claim 1 , wherein the form connector is penetrable to permit a nail to be driven therethrough into the form.

8. A tie system as claimed in claim 1 , wherein the form connector is made from a material selected from the group consisting of wood and polymeric material.

9. A tie system as claimed in claim 1 , wherein the backup wall connector is shaped to at least substantially prevent leakage of cementitious material out of the aperture in the form.

10. A tie system as claimed in claim 1 , wherein the form connector is removably connectable to the form.

11. A tie system as claimed in claim 1 , wherein the form connector is removably receivable in the backup wall connector.

12. The tie system as claimed in claim 1 , wherein the form connector is generally planar.
