First Claim
1. A system for securing adjacent edges of a first metal-backed wallboard panel and a second metal-backed wallboard panel on a wall structure the system comprising:
- a plurality of spaced-apart metal studs, first and second metal-backed wallboard panels, each wallboard panel comprising a drywall panel having a respective metal backing secured thereto, the metal backing of each wallboard panel having a first surface attached to the respective drywall panel and having a second surface parallel to the first surface, the metal backing having a backing thickness between the first surface and the second surface;
a strap having a first surface and a second surface, the strap having strap thickness between the first surface and the second surface, the strap having a length selected to extend at least between a first metal stud and a second metal stud, the strap including a plurality of partial cutouts, each partial cutout including a transverse portion and a stem portion, the transverse portion having a first engagement edge and a second engagement edge, the stem portion having a first end connected to the first engagement edge and the second engagement edge of the transverse portion and having a second end connected to the strap, the stem portion and the first and second engagement edges of the transverse portion having a common thickness the same as the strap thickness, the second end of the stem portion extending substantially vertically from the first surface of the strap such that each of the first engagement edge and the second engagement edge of the transverse portion is spaced apart from the first surface of the strap by at least a selected gap distance, the selected gap distance being the same as the backing thickness.

Abstract
A system secures adjacent edges of a first metal-backed wallboard panel and a second metal-backed wallboard panel on a wall structure having spaced-apart metal studs. The system includes a strap having a first surface and a second surface. The strap has a length selected to extend at least between a first metal stud and a second metal stud. The strap includes a plurality of partial cutouts. Each partial cutout includes a transverse portion and a stem portion. The transverse portion has a proximal edge. The stem portion has a first end connected to the proximal edge of the transverse portion and has a second end connected to the strap. The second end extends from the first surface of the strap such that the proximal edge of the transverse portion is parallel to the surface and is spaced apart from the surface by a selected gap distance.
