Then There Were Eight

After the threaded rods were trimmed, a torque wrench was used to tighten the nuts to HILTI’s requirement, 60 PSI.

Before the team left for the holidays, the walkway structure was all put up! Thanks to Rowe and Jeff’s help the team finished setting up all eight wall plates, and a few days later Devin and Charlie brought some extra muscle and to site. This facilitated lifting and bolting the “arms” and struts into place. The arms, being the assembly of the three horizontal plates welded together, on which the grate will sit. And the strut is the tube that connects the “arms” to the two plate tabs at the bottom of the plate bolted to the wall.

The future main entrance to the walkway, and point where levels were checked throughout the instalation of the brackets.

A 3x4x1/4 inch angle supports the south end of the grate, which is equivalent to only using half of the bracket.
