How do we make the connection from stadia seat to support raker?
A pin that is field “shot” onto a steel support bearing or a pin that is placed in a field drilled hole in a precast support raker works best. This type of connection allows for field tolerances. The hole in the horizontal seat surface is typically grouted to lock the connection in place; a cover sealant can be used to protect the connection. A free or slide type variation of the pin connection can simply be made by placing a rectangular tin cap over the pin prior to the grouting of the hole in the horizontal seat surface.
