Seismic clip assembly for wall claddings

A structural seismic clip assembly for coupling exterior wall cladding to a primary building structure, the assembly being configured to support vertical loads of the wall cladding and out-of-plane loads, the assembly comprising:

• a U-shaped clip comprising a base, a first flange extending from a first side of the base, and a second flange extending from a second side of the base, the base configured to secure to the primary building structure in a fixed position via one or more fasteners;
• a load-bearing subframe structure configured to support the exterior wall cladding in a fixed position relative to the subframe structure, the subframe structure comprising a first vertically elongated aperture on a first side and a second vertically elongated aperture on a second side opposite the first vertically elongated aperture;
• a threaded rod configured to extend from the first flange, through the first vertically elongated aperture and the second vertically elongated aperture, and through the second flange, the vertically elongated apertures being configured to permit vertical sliding movement of the subframe structure relative to the U-shaped clip while the U-shaped clip remains fixed to the primary building structure;
• wherein the exterior wall cladding is configured to be coupled to the subframe structure;
• and wherein a first spring mechanism is coupled to a first portion of the threaded rod, the first portion interposed between the first flange and the subframe structure, and a second spring mechanism is coupled to a second portion of the threaded rod, the second portion interposed between the second flange and the subframe structure.
