Threaded Rebar
Threaded Rebar
(OP)
Dear all,
There is any stander talking about threaded Rebar, its tolerance and its specification and can I assume the rebar as bolts and nuts and apply its specification on rebar material?
thanks

Important Note:
Not all all-thread bars meet the deformation requirements for rebar (deformed bar) per ASTM standards. You cannot expect to put an all-thread bar in lieu of a rebar and expect the "exact" same behavior in terms of development length etc.
What are you trying to use the all-thread bar for?
RE: Threaded Rebar
These are big bars that are turned down and threaded. So you do get actual rebar behavior with their embed. But it's really big stuff. I wonder if a machine shop could do the same with smaller sizes?
What's the application and load?
RE: Threaded Rebar
As azcats asked "What's the application and load?"
RE: Threaded Rebar
wahts the essential variable about it (how i can reject or accept the threaded part)

RE: Threaded Rebar
Can you get by with regular bolts... or can they be fabricated from rod with a heavy hex head nut welded at the bottom and threaded at the top?

Be careful with your material selection. 500 MPa is not a load, it is a stress, and that is about the ultimate limit for commonly available reinforcing bars. Once you thread a bar, the load carrying capacity is reduced considerably, both from the reduced area and from the fact that the outer skin of a reinforcing bar is stronger than the centre. As mentioned above, there are manufacturers of reinforcing, e.g. Dywidag, Reid, which will accept a nut.

RE: Threaded Rebar
The question was regarding the use of threaded bar in lieu of conventional rebar. What you are mentioning is parallel threads (cold forged) vs. tapered thread couplers.
RE: Threaded Rebar
Make sure your coupler is compatible and is strong enough if you use threaded rod. Can be the weak link.
