Abstract
An edge joist is provided for installation along an edge of a wallform sheathing panel. The edge joist is generally formed as a S-beam. A front flange thereof is generally L-shaped and engages the rear surface of the panel at one edge thereof. A rear flange is arranged generally parallel to the front flange and has a provision, such as a T-channel bolt slot, for connecting to wallform walers. A stepped web connects the lower edge of the front flange to an upper edge of the rear flange, and preferably includes a lower web plate extending back from the lower edge of the front flange, a riser extending slopingly back and upward from the rear plate, and an upper web plate extending rearward from the top of the riser to the rear flange. The front flange can have a toe plate overlapping and protecting the panel edge and a flange plate extending upward along the rear surface of the panel. Preferably, beads are formed along the lower surface of the web lower plate to form seals when edge joists are butted together. The edge joist so constructed will nest securely in a shear wall support bracket. It can also be used to form a secure joining member with a like joist on an adjacent wallform panel.
