Abstract:

A veneer wall consisting of a plurality of masonry units held together by conventional vertical and horizontal mortar joints. A plurality of straight horizontal tie members with opposite ends and a center portion have one end thereof embedded in one of the mortar joints to cause the tie members to extend horizontally outwardly with respect to the veneer wall. Insulation panels having inner and outer sides extend in spaced parallel relation to the veneer wall with the panels being secured to the outer ends of the tie members. A solid poured-in-place concrete wall fills the space between the insulation panels and the veneer wall and embed the tie members. A rigid stud wall of conventional constructions is imposed on the outer side of the insulation panel. The method of the invention forms a veneer wall on a support means from a plurality of masonry units held together by conventional horizontal and vertical mortar joints; thence embedding one end each of a plurality of straight horizontal tie members into the mortar joints while the veneer wall is being formed, and before the mortar joints are set; hence placing a plurality of insulation panels in parallel spaced relation to the veneer wall to create a vertical space therebetween; thence securing the insulation panels to the outer ends of the wall ties; and then filling the space between said veneer wall and said insulation panels with plastic concrete and allowing the concrete to set.
