support for ceiling fan

afternoon all. we are doing a touch of remodelling and have converted one room into two. we are taking the opportunity to add ceiling fans while the ceiling is out. the structure is a steel framed shed and the ceiling will be lined with plasterboard. the sheeting will be attached to 25mm top hat battens. What is the best method to create a stable base to which the ceiling fan can be attached?

Attachment 527543Attachment 527544

I am thinking that i cut a notch into the end of each beam so that they sit down to the same plane as the top hat on either side. Once notched and sitting flush, attach each one in position alongside the top hat batten. Thus the base of the fan has something solid to which it could be attached.

any other ideas?

Exactly what you described :2tsup:

Whatever you end up doing, when done, do some careful measuring from a few fixed points in the room (triangulation), and take notes. So, that when the plasterboard is up you'll be able to find the precise location. You wouldn't want to be cutting multiple holes through your new ceiling in search of the right spot. And make sure you know where the cables run. The last thing you want is to be drilling through one.

i've marked the floor beneath the centrepoint but will do as you suggest also. i'm an overkill kind of guy.:B

Screw the timber to the truss and screw on another bit the same thickness as the tophat. drill a hole through the middle for the wire. Use a plumb bob with your floor marking to find the exact spot.
You can poke the wire into the hole and attach a bit of string so that when you cut the plaster you don't have to go fishing, just pull the string.

good idea with the bit of string. cheers.
