Nails: Concrete, installation

[Big Shed]

Groggy, I built my own house and didn't use concrete nails or spaghetti for attaching the frames to the concrete. I used Dynabolts, takes a bit longer and costs a bit more but when it blows a gale I can sleep at night.

Belts and braces........................

For attaching anything non-structural to concrete or brickwork I use spaghetti, which I reckon is one of the best things since sliced bread.

I have about three short walls to put in: one 1.5m, another 1.5m, a 1.5m with a door in it and a larger 3m wall. I reckon about 20-30 nails max.

Given what everyone said though, dynabolts are looking good about now.

Thanks for all the advice!

Groggy,

Unless you are also going to tie the rafter/trusses to the top plates and the top plates to the studs and then tie the studs to the bottom plates, using dynabolts will (probably) keep your bottom plates in place, but the remainder of the structure would be able to be torn off by the wind.

As for concrete nails, one nail near the base of each stud is plenty. Fixings through bottom plates are primarily used to prevent horizontal movement of the plate and so allow us to push and pull the timber straight. Those fixings are not designed to prevent your house blowing away which here in Victoria, is a very remote possibility.

HTH,


Mark.

Yep, did all of those, as far as I know they are actually required by the building code.............

Yeh, they got tough with tie down procedures and amended the codes about ten years ago now. It's a bit of a pain tying down a bearer through ant caps without letting the little buggers through.
