 Posted: Thu Jun 21, 2007 2:10 pm Post subject: Fixing to underside of Galv Lintel |
  |
|
|
I have a fairly newish house which has a set of 2100mm wide french doors. I want to remove these and fit a set of TOP HUNG folding/sliding doors. The way the system works is that the head of the frame has to be fitted to the structure above.
The galvanized lintel supports both the outer and inner skins and with a cavity of 70mm. Not sure on the exact type/reference etc.
Can i drill through the lintel into the blockwork above in anyway to fix the head of my frame? It asks for fixings of around 400mm centres around the middle of the opening so it's not asking for many holes.
If not, could the insulation within the cavity of the lintel be removed and a hardwood packer chemically fixed into the area work?
The doors (3 equal leafs) with be 120kgs total.
Thanks
Andy |

I cant see why not, when you say top hung do you mean the bottom of the doors run in a track on rollers or something like that,? In which case there is not a lot of weight on the lintel and you could drill and tap the steel lintel, or use self tapping screws. If it takes the full load of 120KG then i would look at some other way to fix the doors.Removing the insualtion part is not a good idea, but you could probably put a plate of steel over the gap and fix the track to that like before with bolts or self tappers.

Nick. The doors are hanging from a 50x50 steel channel that fixes to the head of the frame.

Hi LyNx,
I would just drill through the steel lintol with a slightly bigger hss bit then fix as usual using a masonry bit and normal fixings.
I say this as i have just fitted some sliding/folding door gear in exactly the same scenerio as yours.
Hope this helps

I have been hoping someones done this before, thanks.
What sort of weigth do these lintels support. I take it adding 120kgs is not going to make much difference?  |

120kg wouldn't matter a jot.
