What ceiling timbers can I rely on to hang bicycles from?

[glider26]

Hi,

We‘ve just moved into a recently built (2016) detached house which I believe has a first floor concrete slab. In the garage below (ground floor) I’d like to screw a (say) section of 1in x 4in timber to the ceiling, to which I’ll have attached some hooks which will each support a bicycle. The ceiling (photo below) appears to be made up of plasterboard. I’ve scanned it with a joist detector and have located what I think are joists, and my plan is to screw my sections of wood with hooks to these. My question is, given that the first floor is a concrete floor and I that I have no idea what structure supports it, is it reasonable to expect joists and to use these to screw my contraption into?

Cheers.

Lift to floor covering to identify the floor construction. Fix a batten at right angles to the joist to spread the load.

Yes that was my plan, batten running across 3 joists. See pic below of carpet grippers nailed to (I think) precast concrete slabs (first floor). My question is, what is supporting these slabs (timber joists?) and can I drill into it from below in the garage?

Poke a hole in ceiling where you plan to hang bikes any damage will be hidden by plate .

Thank you but before I start drilling holes, I would like to know what is on the other side of the plasterboard ceiling with such a (concrete) floor above it. That is the information I’m after and why I started this thread. If someone can answer that question then I’d be most grateful.

You expect someone on an internet forum to know what's on the other side of your floor?

You'll need to make a hole in your ceiling to see what's up there.

Haha! I take your point. I was hoping that someone familiar with this sort of construction would be able to tell me exactly what was the other side of the plasterboard, in the same way that in my old house (joists and floorboards) I could say that above the plasterboard there’d be 600mm spaced joists running from one LB wall to another. But fair enough, I’ll drill and work it out.

You can also look at the floor in the room above.

Assuming it is a concrete floor, as the OP intimated, it will be beam & block with a screed, concrete planks or a slab that will then have a suspended ceiling beneath, he needs to understand what that method of suspension is. You cannot determine that from above.

Assuming

I believe has a first floor concrete slab

Looking at it is better.

How high is the ceiling?

Thank you! Finally…

Maybe answer my question

How will ceiling height help the OP?
