I have a problem with a floor construction that was carried out by a construction company I hired, and the designers do not want to take responsibility for the solution and have directed me to a light beam manufacturer.
As you can see in the attached sketch, it is a truss in a light beam that is 250mm high, where an OSB board is to be lowered between the beams to then lay Minerit boards and tiles.
The support for the OSB boards is two 45x170 studs, which rest on the subfloor, which in turn rests on the lower flange/stud of the light beam.
The dimensions of the part of the floor are 2000mm x 2200mm. A staircase will also be on the floor. The light beams are 7500mm long and have 3 support points.
My concern is whether the lower flange of the light beam can bear the weight of this type of construction.
Can someone help me?

I wouldn't do that just like that; the person who designed the beam probably intended for the load to come from above on the upper flange, now there will be some tensile load in the web of the beam, which I suspect is not the intention.
If a structural engineer doesn't want to take responsibility for this construction, I would be cautious.
