Installation of a door in aerated concrete. I use a simple way to make a reliable fastening in a "fragile" material.
Looking at how many make steel frames, when installing doors (so that it does not fall out of aerated concrete), I was also afraid that I would have to tinker with it. But in practice, everything turned out much easier.
After installing windows with your own hands, I became convinced that the theory that normal fasteners cannot be made in aerated concrete is just someone's bad experience, which has nothing to do with me.
Aerated concrete dowels, normal self-tapping screws, and polyurethane foam add up to an excellent result.
At the sight of such structures ...
Which very reliably hold the door in the opening, it seems that if you make fasteners in the block itself, then the door will immediately fall out ...
But in reality, these are prejudices.
Everything is made much easier with simple mounting plates.
In aerated concrete, the main thing is not to make fasteners at the very edge of the blocks. Here the plates help to "move" the attachment point from the edge into the wall.
For this, I used T-bars.
And only because in them there are large holes for bolting. And so there is no difference ...
Through this hole, I attached the plate to the door frame (three plates on each side).
And already in the opening I made fasteners for self-tapping screws and dowels for aerated concrete.
At the same time, the door does not hang in the air, but stands on mounting wedges(although some taught me to clean them up after editing ...).
At the same time, the door already sat like a glove without foam. And after foaming, it won't go anywhere ...
✅ Of course, many will say that they pick it up with a crowbar, or pull with a tractor and everything will break out... But if you wish, you can do the same with concrete walls.
For me, operational reliability is paramount! And with such fasteners, it is completely achieved.
