Anchor Bolts

plumb_bob | Posted in Building Code Questions on

I deal with the BC Building Code. It specifies certain diameters and spacing of anchor bolts but does not specify that they must be cast in place (wet set).

On projects with ICF foundations, or also structural slabs, the contractors like to use wedge anchors or sleeve anchors for ease of installation.

Opinions on these different types of anchor bolts?

Note: I am not in a seismically active zone and our wind loading is low.

    Bob,

    The other end of the spectrum is how they frame in Alberta, setting a ladder of 2"x4"s into their forms before pouring and nailing the sill plate directly to that. In areas that experience low shear forces, isn't the anchoring essentially to set the framing square?

    Ah yes I remember framing in the lovely Alberta winters.

    I always think of "structure" as building for the rainy day: the 1 in 200 year wind storm, grandpa backing the truck into the house, a big quake off of Haida Gwaii. Or (this happened to me) an ice jam damming the river and the flood waters trying to float your home off the foundation during construction.

    I put in an interpretation request and will let you know what they say.

    I like Simpson Titen HD anchors--just drill and install, like a big Tapcon.
