Hollow core laid to a fall

Hollow core laid to a fall

Hollow core laid to a fall

(OP)
has anyone designed a hollow core roof with the planks laid to a fall to minimize weight and to keep the topping a constant thickness?

RE: Hollow core laid to a fall

Are you talking about 'tapered' HC planks?... if so, then no, they are extruded and a uniform thickness. You have to vary the topping thickness... check with local HC supplier.

Forgot the obvious... change the bearing elevation...

Yeah, I'm talking about varying the bearing height at each support. These are long spans (12m) and the topping would be too heavy over that distance if tapered.

RE: Hollow core laid to a fall

You questioned whether anyone had done it, and I haven't seen it done, but don't see any fundamental reason why it wouldn't work.

RE: Hollow core laid to a fall

I have seen it done once, though at a low grade. I don't see any obvious reason not to do so.
