US Patent 12077958 Wall system with novel structures and method of construction thereof

A concrete foundation with reinforcements is formed on a substrate. A first inner wythe horizontal layer and a first outer wythe horizontal layer are printed using a construction material mixture from a 3D printer. The first inner wythe horizontal layer and the first outer wythe horizontal layer are separated by an interstitial space. Additional inner wythe horizontal layers are printed upward on top of the first inner wythe horizontal layer to form a composite inner wythe. Additional outer wythe horizontal layers are printed upward on top of the first outer wythe horizontal layer to form a composite outer wythe. At least one wall tie is placed between the composite inner wythe and the composite outer wythe. A sill cap is installed on top of the composite inner wythe and the composite outer wythe. An anchor mechanism is installed into the sill cap.
