ABSTRACT:
A metal weldment and method of manufacturing the same in which the metal weldment is embedded in a concrete slab-type structural member. The weldment has a central plate having a planar, weldable surface along an edge of the concrete slab, the weldable surface is perpendicularly disposed to the horizontal plane of the concrete slab. There are a pair of outstanding arms extending from the weldable surface and which are embedded in the concrete slab. The outstanding arms have a constant height across their length and support a steel reinforcing mesh at a predetermined height during the concrete slab casting operation. A blockout is provided to the mold during the casting operation to keep the top edge and front surface of the weldable surface free and clear of concrete. This provides for thermal expansion of the weldable surface and minimizes cracking and spalling of the concrete during welding. The blockout is removed from the mold after the concrete has hardened and can be re-used.
