1. A fire-rated wall assembly, comprising:
a first wall structure comprising a first wallboard;
a second wall structure, the second wall structure comprising a second wallboard and positioned laterally adjacent to the first wall structure, the first and second wall structures defining a vertical wall gap therebetween, the vertical wall gap comprising a space defined between the first wall structure and the second wall structure, and bound by opposing edges of the first wall structure;
an elongated angle profile fastened to a vertically-extending corner of the first wall structure that is laterally adjacent to the second wall structure, wherein the elongated angle profile comprises:
a first leg; and
a second leg, wherein the second leg is oriented at an angle relative to the first leg, wherein the first leg comprises a length that is greater than a length of the second leg, wherein the first leg and the second leg each includes a free edge and a connecting edge, the connecting edge positioned opposite the free edge, the connecting edge of the first leg and the connecting edge of the second leg being connected to one another at a corner, wherein the first leg and second legs are formed from a single piece of material, wherein the length of the first leg and second leg extend perpendicular to a height direction of the first wall structure and the second wall structure; and
at least one fire-resistant seal positioned near the free edge of the first leg away from the second leg, the at least one fire-resistant seal comprising an intumescent material,
wherein, in use, the first leg of the elongated angle profile is disposed within the vertical wall gap such that the at least one fire-resistant seal contacts the second wall structure and the elongated angle profile seals the vertical wall gap while allowing relative movement between the first and second wall structures.
