Abstract: A slab anchor that is resizable in the field to accommodate different thicknesses of slabs. The anchor may have a top assembly and a bottom assembly that are joined by pipe such as widely available PVC pipe. A contractor can simply determine the desired width of the slab (which determines the height of the anchor) and cut a PVC pipe to the length necessary to make a slab anchor of the needed height. This system allows contractors to keep on hand only a single type of slab anchor, and to customize this anchor easily at the last minute for each slab. The top assembly of the anchor may have a coil that a fastener screws into after the concrete is poured; a coil protector screw may be placed into the coil during pouring so that concrete does not fill the coil, and removed thereafter to install the fastener.

Abstract: A reinforcing stud for a stud rail includes an elongated stud body defining a first diameter. A first load transfer head is disposed at one longitudinal end of the elongated stud body. A second load transfer head is disposed at the other longitudinal end of the elongated stud body. The second load transfer head includes spaced apart mounting flanges on an end surface thereof. The mounting flanges define a channel for receiving a rail. At least one of the mounting flanges has a threaded opening through a wall thereof for receiving a set screw.

Abstract: An assembly for connecting a first rebar segment and a second rebar segment. The assembly includes a first wedge and second wedge, each defining a hollow for receiving the first and second rebar segments, respectively. A first barrel and a second barrel each define a passage for receiving the first and second wedges, respectively. The passages are tapered for mating engagement with the wedges for driving the wedges radially inwardly in response to the wedges being in the passages and axially engaged by the barrels to tighten the wedges about the rebar segments. A cap defines an opening, a stopping surface, and a channel that extends axially between the opening and the stopping surface, receiving the first and second barrels in axial alignment with one another. A coupling connects the cap and one of the barrels, inhibiting axial movement of the barrels out of the channel of the cap.

Abstract: A method and assembly for anchoring a segment of rebar and a plate to a mass. The assembly includes a barrel extending about and along an axis and defining a bore extending therethrough along the axis with the bore being tapered. A wedge having a frustoconical shape extends about and along the axis. The wedge is tapered in conformity with the bore of the barrel for being received by the barrel. A cap is connected to the barrel for closing the barrel. The method includes the step threadedly tightening the cap about the barrel in axial abutment to close the barrel, and further the step of compressing the wedge axially into the bore of the barrel to drive the wedge radially inwardly to provide for a biasing force of the wedge against the rebar prior to said step of threadedly tightening the cap about the barrel.
