Drilling into concrete lintel

Hi,

I am putting up a false ceiling using 3"x2" timber. I have screwed the frame to the wall above the window. I have used 10 mm x 100 mm frame screws made by rawlplug. The rawlplug goes about 60 mm into the lintel. The screws are spaced out by about 600 mm.

I have been reading that some people don't screw into lintels, others do. I need the support for the ceiling over this section. Are there any definitive rules about screwing into lintels like this? The lintel is 160 mm x 160 mm so it's quite thick.

Best regards
 
Screw a wood trimer over it, and secure the new timber work to that. If you hit the rebar in the lintel when drilling in to the concrete lintel, its integrity will be compromised. If it is a lintel with two bars, depending on which way up the lintel it is laid the bars can be quite close to the surface.

Put up a photo of the window area, fixing a couple of 10mm bolts and supporting a ceiling partly off a concrete lintel is a bit different to putting up a curtain rail.

If the re bars are at the top, the lintel is upside down!

Doubt it would be changed at this stage o_O

Hi,

The lintel sits above a kitchen window with a concrete slab on top of it. See pic:

This slab is about 9.5 cm thick.

Inside the kitchen looks like this above the window:

The bolts sit just under 10 cm from the underside of the slab.

Above this I think that there is a lintel for the inner brick course. I have lifted the bedroom floor and I can see a lintel which is atleast 15 cm thick above the kitchen ceiling/under the bedroom floor. See pic:

Finally, there is another exposed lintel above the kitchen door which is 16 cm thick. So if this window/bay lintel is the same, I suspect that I have drilled into something below the lintel (perhaps into the concrete slab). Here is a pic of the exposed door lintel:

What are your thoughts? Do you think that this is safe?

Best regards
