Hello, I am planning to build an extension of 20 m2 with 6 pier foundations underneath, where I plan to cast in HERO STOLPSKO JUSTERBAR TYP FLEX.

The extension consists of a floor structure 45*145 with insulation and floor particle board
1 wall with sliding door sections 4.35 total width,
1 wall with 3 pcs 2-pane windows width 1200* height 1300
1 wall framed 60 cc with insulation, double gypsum & panel. (Fire rated)
No wall against the existing house
Roof trusses 17 degrees in 45*120 lumber and insulated roof with outer roof in plywood & sheet metal along with inner roof in plywood.

How can you begin to understand what the build will weigh?
How can you determine how much weight each HERO STOLPSKO JUSTERBAR TYP FLEX can support, based on the information I received from the supplier, I have no idea how to calculate this.

  • Adjustable joist hanger with a metal U-shaped top and threaded bolt for height adjustment, used for constructing a building extension on plinths.
Hello,

To give a good answer, one would need to see drawings of the building as well as know the snow zone and the layout of surrounding buildings.

Assuming that Fr1d in the table is the vertical load on the post base, each post base can handle around 670 kg. So you'll need to estimate if the building, including people in the building and the snow load on the roof, results in a higher load than this per post base.
