Here is what's stated in the description of Hajom sliding doors:
The top frame should be fastened level against a supporting stable beam – see fig 2 or fig 3. It is important to maintain the recommended 20 mm clearance between the beam and the top frame to allow the beam in the wall opening to settle the 10 mm that are tolerated in a structural calculation. Load-bearing construction with oversized wooden posts can only load the supporting post – but not the top frame otherwise. Use a non-compressible material between the post and the beam.
I thought Bosse would comment on it since it was his proposed solution that you want to change.
I don't know your thoughts behind arranging a 6-meter-wide opening, but personally, I would have considered placing a pillar in the middle and using glulam. You would have a significantly easier journey then.
3 posts 50x150 (it will probably be 45x145) are a bit overkill but not a disadvantage. Fasten them together properly. A little play at the end is good. Whether you can use beams instead of brackets to prevent tipping mainly depends on the space. At the ends, it certainly works.
I think you should also study the opening in plan. If you have a 6-meter long sliding door section, the maximum opening won't be 6 meters when you have moved all sections to their respective ends (depending on the number of tracks). The beam and column don't necessarily have to be directly above the sliding doors.
Since IPE 330 is 150 mm wide, I thought it would fit with unplaned framework as it is available in 150 mm. The space for the support is no problem, so I'll go with 3 pieces.
I was thinking of going with a 3-track for maximum opening. According to information, a 3-track can be opened to 65-67 percent of its total opening.
3-track also works quite well because I need to insulate both outside and inside the beam. The wall where the beam is located will therefore be quite thick, which suits a 3-track system that is 220-240 mm deep.
If you have six sections of about 1 meter each and three tracks, and you slide the sections to the ends, the free opening becomes 4 meters, i.e., 2/3 of the distance. Placing a column 1 meter in from each direction does not affect the movement space but significantly reduces the span.
No, a total of two pillars with four meters between them. Yes, the frame must lie outside the beam, but that can't be an unsolvable problem. D has the world's eaves.
