Abstract
An insulated concrete wall is constructed by securing at least one tie assembly (14) to a panel (12) of insulative material, securing the tie assembly and panel to a pair of spaced forms (60, 68), and pouring concrete into an open space defined by the forms adjacent the panel. The concrete is then allowed to set, and the forms are removed. The tie assembly (14) includes an elongated tie (16) having a central region (24) adapted to remain in place in the wall subsequent to construction and a pair of opposing end regions (26, 28) adapted to be detached after removal of the forms. In addition, the assembly (14) includes an elongated retainer body (18) formed of heat insulative material and received on the tie (16), and a pair of face plates (20, 22) retained on the body on either side of the panel (12).
Claims16
A concrete wall presenting first and second exterior surfaces, comprising:
- a layer of concrete;
- at least one layer of insulative material;
- and
- a tie assembly for retaining the layer of insulative material against the concrete in the wall, the tie assembly including
- an elongated retainer body formed of heat insulative material and including a first region embedded in the concrete and a second region extending through the layer of insulative material to the first exterior surface of the wall, the second region including an outer end disposed adjacent the first exterior surface,
- a first face plate formed of synthetic resin material and being retained on the body at the outer end of the second region against the layer of insulative material, and
- a second face plate retained on the first region of the body and being at least partially embedded in the concrete the face plates being spaced from one another by a distance adapted to accommodate the layer of insulative material so that the material is retained against the concrete in the insulated wall, the retainer body including a laterally extending flange adjacent the outer end of the second region for retaining the first face plate on the body, the retainer body and first face plate presenting a generally planer outer surface disposed in a plane generally parallel to the first exterior surface of the wall.
