Trimmer Bars

[CWEngineer]

I was looking at some plans and noticed that some temperature bars in the wall stem were labeled as "Trimmer Bars" - I have tried looking at my reference for the definition of a trimmer bar but I still have not been able to find anything.

Appreciate your help, in trying to figuere out what a Trimmer Bar means?

THANKS

Would it simply be a bar used only to support other bars? We call them "carrier bars".

Are they not bars used around edges of openings? Rod busters use this terminology. I have heard some of them refer to lintel, jamb, and sill bar reinforcement for window openings as trim bars.

In the UK Trimmer Bars is the name for additional bars placed round an opening, such as pipe penetrations through an RC tank wall or a large opening. They are usually placed at 45 degrees across corners (assuming horz bars at 0 deg and vert bars at 90 deg).

Ussuri, out here, I have occasionally heard the additonal diagonal bars referred to as diagonal trimmer bars by reinforcing iron workers aka rod busters.

henri2, yeah thats my understanding. But I suppose the term could be extended to include stock steel used to locally strengthen any section of a member. They are basically just extra bars added over and above the normal structural/distribution steel.

Rod busters?! what a cool name. We just have the boring title of 'steelfixer'
