Reinforcing Inserts at Construction Joint 1

[SperlingPE]

I am designing a concrete slab that will stop short of a complete slab pour due to construction constraints. I am looking for a tube/pipe insert to embed at the edge of the pour. I would like to insert dowels into the tube/pipe when the remainder of the slab is to be poured. I am tryign to avoid casting the dowels in the first pour to avoid them sticking out until the rest of the slab is poured. Does anybody make such an item? Should I just go with a pipe that fits the dowel?

It is indeed made. It is called a speed dowel. One half is an insert, the other half is rebar.

For an example go to

Where are you from? Here's another site that might help.

Do these need to achieve full tensin or just shear. I think the above two are just for shear dowels.

There is a lenton grout tube that gives a full strength tension splice.

i've seen the inserts before...not sure what they're called...but they do exist. the ones i saw create the slip joint at the pour back strips for tilt panel warehouses.

Ancon shear connectors are available in the UK, Australia and elsewhere and do what you describe.

If you don't want a movement joint, cast in threaded inserts (ferrules) and screw in rebar with a threaded end when required.

Try Diamond Dowels from PNA Construction Technologies.

These are for shear transfer, not tension or moment.
