KNEE JOINT
















Both the column and the rafters are made from two back to back cold formed C channels bolted together. The joint is a single piece hot dipped galvanised steel C channel gussets fitted inside the cold formed C channels and bolted through the webs. The gusset plates have stiffening. A cold formed C section tie is bolted to the cleat welded to the gusset plate.

Hi Michael, please also comment on the gutter board & brackets all clearly seen here. Keep this in mind as a great box gutter detail ( although I'm sure you already know it well). R.K.

Introduction

I passed this site just after Christmas on my push bike. At first glance it appeared to be an ubiquitous portal frame. However the shining relfections from the frame signalled that it was different. The portal frame was not your normal hot rolled steel UB section but cold rolled. The type you usually see in those kit garages and barns, but this spans 20m!
