About a year ago an inspector recommended we reinforce the thingy that is in the picture below. Apparently it flexes toward the camera when someone stands in the attic. It looks like some kind of free-standing truss to me.
http://picobot.org/attic.jpg Alas I was not able to attend the inspection, and my wife went instead and she does not remember how the inspector told her to reinforce it (she did say he said it was "pretty easy"). It was not an imminent fix, but recommended that no heavy items be stored in the attic until the work is done. A friend of mine recommends attaching a 2x4 to the truss and then to the rafter, but that sounds pretty scary to me (especially as the coils for the heat-pump are just to the left).
So any clues on what the correct name for that framing is, what its purpose is, and any hints to stop it flexing? If I need to get a framer in I'll do that too.
Recommendations? And thanks in advance!
