Abstract: A method for forming insulated concrete wall panels includes the step of positioning a stud wall frame in a casting bed, positioning a support panel formed from a single, monolithic section of foam insulating material on the wall frame with grooves formed in a first face therein on the stud wall frame with the grooves facing away from the wall frame and then pouring concrete in the casting bed over and around the first face of the support panel to form a layer of concrete with portions of the concrete extending into the grooves in the support panel. The concrete is allowed to cure and the wall structure is then removed from the casting bed.

Abstract: A handle assembly is disclosed for tools such as shovels and the like having a primary handle and an auxiliary handle. The primary handle includes first and second legs, each of which has a first end which is securable to a tool head such that the first and second legs extend outwardly from the tool head in generally parallel relation to one another. A primary grip or handlebar extends between the legs at the ends opposite the tool head. The auxiliary handle is slidably connected to said first and second legs so as to be moveable toward and away from the primary grip. The auxiliary handle is removably connectable to the legs and may be stored in a generally planar alignment between the legs to facilitate stacking or the auxiliary handle may be shaped to facilitate nesting of adjacent auxiliary handles of stacked handle assemblies.
