Description

This disclosure relates to exterior wall panels. Conventionally, as described in Patent Documents 1 and 2, exterior wall panels are known as building components such as wall panels, comprising a steel frame member and interior/exterior facing materials joined to the plate surface portion of the frame member. In some cases, functional materials such as thermal insulation are further integrated into the plate surface portion of the steel frame member of the exterior wall panel. The manufactured exterior wall panels are transported to the building construction site and attached to the building's structure at the construction site. The frame members can be assembled, for example, by joining the longitudinal ends of multiple channel steel members, which serve as vertically extending column members, and multiple channel steel members, which serve as horizontally extending chord members. In the frame member described in Patent Document 1, the joints between the column members and chord members are formed by welding. Furthermore, the frame member assembled by joining a pair of chord members to a pair of column members is joined to the face material with adhesive. Furthermore, the exterior wall panel described in Patent Document 2 is provided with a drip edge extending from the lower chord of the exterior wall panel toward the outside of the panel, covering the joint between the exterior wall panel and the lower exterior wall panel. Patent Document 2 states that the drip edge can suppress water intrusion from the outside of the exterior wall panel.
