Steel: Embed Plates

This video is about embed plates and they're basically used to attach steel members to concrete or masonry members. So it's used in precast concrete, tilt-up concrete, pre-stressed concrete, cast-in-place concrete, and masonry used for beam bearing plates or lintels, underneath lintels. So looking at this, that's what they look like. It's a plate with shear studs welded to it, and the shear studs go in the concrete, they're cast in, and then a steel member is attached. So looking at this image, for example, here's the embed plate and we can see it on the face so that when this is cast, they go back and they expose these plates. This is in the case of a tilt-up wall. And we can see here, they go back and they attach a steel member to a precast or a tilt-up or some kind of concrete member. So looking at this a little bit closer, if you need studded plates or embed plates on both sides of this tilt-up wall, then they're going to lay some straight on the surface they're pouring on. But then they have this piece of wood and here's another embed plate that is attached to this piece of wood and then is cast in the concrete. And the studs, the sheer studs, anchor it in the concrete so it doesn't go anywhere. Here we are again, a studded plate or an embed plate attached upside down in the concrete and embedded. Here we can see the plate and there's shear studs down there attaching it to the concrete, embedding it in the concrete. A beam bearing plate, it's embedded in masonry or maybe a lintel. This one has studs sitting in the concrete, the masonry unit that is filled and grouted in that cell. Here's a cast and place situation with these plates embedded in the concrete formwork and then a steel member is attached to these plates. Okay, I think I said everything I want to say about these. Very good.
