Toeplate Req.'s for Grating Penetrations ( piping )
Toeplate Req.'s for Grating Penetrations ( piping )
(OP)
I am trying to find out if there is a code somewhere that might have requirements for toeplate/banding around piping penetrations through grating. We have everywhere from 1" to 12" air/ammonia/steam & water piping that penetrates grating. In our general notes , we have the details on HOW to do the banding should it require it but does not say where to use it - on which pipes ?
I do not know if it would say in D1.1 , B3.1/B31.1 or the IBC maybe? as I do not have these codes on site at my disposal
Thank you for your time

Is the deflection of the grating compromised by the penetration? If so, you might require reinforcement in addition to a toe plate, though they could be combined.

Combining them is an elegant solution. Welding every other bar to a slice of schedule 40 pipe [flush at the bottom of the grating, extends 4" above grating] will use the strength of the pipe to carry the grating loads around the hole you cut in the grating. If you don't use this solution, you typically have to call back the ironworkers to add junior members to support the grating at the hole that the pipe folks just cut.
