What does this architectural symbol mean?

[Tony L]

I'm checking through the drawings my architectural technician has done for me.  Can somebody let me know what this architectural symbol means please?  It's used in the detail drawing, below.

Looks like Sputnik 1 has landed . But it’s unlikely to be an architectural requirement for plans .

It may be @Pocster's WC seen from above with him on it...

Sack trolley, clock hands or the image is a standardized symbol (IEC 60417 - 6284) used in technical documentation. 

No idea.

Is it the new name for Prince Andrew.

It’s similar to a machine surface symbol.
