I am in the process of building an Attefall house where the floor joists rest on beams mounted on pillars, very similar to the picture below. The house is about 4x6m, the floor joists are 45x170, and the beams (3 of them) are 45x95. Do you need/should you secure the house's floor joists to the beams with, for example, metal brackets, or can the house "sit completely loose" on the beams? I have no sense of whether a storm or something else could move a house...
Maybe it's common to attach the joists only to the middle beam to prevent them from swaying sideways, but that should be resolved when you lay the interior floor (I will have solid pine flooring)?
I've googled a whole lot without getting any wiser. It would be very interesting if someone knows how you're "supposed" to do it or what is commonly done. Thanks in advance.
I used joist hangers to be able to have a slightly higher ceiling height. If you place them on top you can use angle brackets, but I think it's sufficient to use a number of skew screws.
They must absolutely be attached. You can use angle brackets or so-called fork anchors. Use anchor nails or anchor screws. Do not recess the floor joists between the support beams. You will lose stiffness, which must be compensated with larger dimensions.
Thank you for the reply!
Okay, it seems like they should be attached then. Does that apply to all the places where the floor joists cross the beams, i.e. 3x12=36 angle brackets in my case? Or is it enough with the corners and the middle maybe? Or at least every other floor joist?
Thanks for the response again =) No one has any other viewpoint, so it's just a matter of going ahead? Sounds drastic with 36 fastening points I think but better safe than sorry...
