K24 195-45 rule

[valjn]

If I am going to lay flooring over a basement that is 4m wide, is it okay to use a K24 195-45 stud?
CC 600 and a 25mm wood floor will be laid over it.

I think it might be a bit on the weak side. 45x195 is specified to have a maximum span of 3.1 meters for deck construction. K12 in itself, K24 gives an additional 30 cm.

In an exact measurement it is 3.6m. Would 195mm work otherwise I have to chisel away concrete or make notches in the joist.
Good suggestions on how to best fasten them. They are on a 100mm concrete edge. Angle brackets or..
Does anyone have a table for K24?

Looking at Töreboda Lagerträ. For your dimension, they recommend LT 42x225 or Kerto-S 39x225 as the minimum dimensions.

Checked Träguiden.se and it seems that you might have difficulty with the intended dimension.

These are also the smallest dimensions sold, so perhaps a smaller glulam beam would have worked if it were available.

These are also the smallest dimensions available for sale so it might have worked with smaller glulam if it existed.

Indeed, but as mentioned - even the Wood Guide's tables with solid wood recommend larger dimensions.

The arrangement, 100mm is not much for the joists, which can tend to flex on the short setup. But it is certainly possible with sturdy angles on both sides of the joist. Cross-bracing is a solution to make the floor rigid and without flex if 195X45 is the limit of what fits.

What do you mean by krysskolva?

 

[saturnus]

use the Forum's search function, there is a lot about krysskolva:

Anyone have a table on K24?

This is how the table from the wood guide looks.
The dimensions in table 1, the one with thinner dimensions, assume a construction with screw-glued floor chipboard.
