Hello!

I have bought a house from '74 that will undergo extensive renovation. Among other things, we will install a lot of sliding sections, and in conjunction with this, we wish to raise the frames about 15cm to create larger sections with more glass.

Along the short side of the house, there is currently a window section with a beam above it
(B202 on the drawings, marked in red)

On (or together with?) this beam lies B201.

We are trying to figure out where the beam is and at what height. We have been unable to find any information in the drawings about where they have placed this.
B201 is "above" the living room (about 250cm ceiling height), and B202 can be located almost anywhere.
In a perfect world, B201 would be directly above or welded together with B202 and therefore at a height of about 234-250cm.

Is there anyone with experience or insight on how construction was done back then? Is it reasonable to assume that they placed the beam on top of the other, or that they welded them together?

In short, I need input on where you dear members think B202 is likely to be placed height-wise.

Otherwise, the construction is very good.

Thankful for any help!

You don't have any sectional drawings?
 
Unfortunately not, no.
 
I am quite sure that beam 201 rests on beam 202. Anything else is unreasonable. It is not HEA but HEB 140 and 160 respectively. Then one should always show the entire drawing including all labels. The latter often contain important information.
 
Do you mean that 201 is on top of 202? Then 202 should be from about 235cm up to the ceiling height of 250cm?
Sorry if I'm not very knowledgeable in the field, I will try to get more drawings.

Is it common to place something between the beams or are they usually just placed directly on each other?
 
It probably depends on the height conditions. The beams should be anchored to each other.

Ok.

ceiling height is 2.50.
Found some section drawings but they don't say much, I think.
