Ship ladder to stair landing typical connection

[generick]

Hello,

These are the only pics I've received from a client who is looking to build an industrial stair similar to this. Judging by the poor quality pic of the ship ladder consisting of C-channels for stringers - how are these normally connected at the landing? It appears to be "floating" and I can't think of any other way as to how frame this.

Any detail or tips would be greatly appreciated!

There's probably a nominal connection at the top and bottom to keep in in place. The demand on those connections is generally quite low.

I suppose the top will be more of a slip-critical connection probably via angles and bolts. I am just having a brain-fart thinking of the connection as I have steel grating above the support beam that spans from column to column. I did a quick rough sketch below.

Onboard ship we simply weld a vertical flat bar to the deck that laps up against the C channel. This allows for the connection to be bolted or welded with simple weld geometry (no inside corners). If bolted make sure you put the bracket on the flat side of the C, it makes installing and removing the ladder very difficult if you don't

Two options. #2 is what Tug is describing.
