Chemical Anchors and fire

Chemical Anchors and fire

Chemical Anchors and fire

(OP)
It is common practice, and often unavoidable, to use chemical anchors in structural retrofit projects.

My concern has always been the complete lack of fire resistance for chemical anchors.

I will use mechanical anchors when approriate, but this is not always an option.

What practices do people use to avoid these issues?

RE: Chemical Anchors and fire

Overhead application of chemical anchors are prohibited but the use may be permitted for shear applications.  For overhead applications, mechanical anchors are commonly used but screw type anchors may also be used if allowed by the local building official.
