A central rod passes through a form-board. A first disc is attached to a first end of the central rod. The first disc abuts to a first side the form-board. A second disc is attached to the central rod between the first end of the central rod and a second end of the central rod. The second disc abut to a second side of the form-board opposite the first side. A third disc, attached the second end of the central rod, is configured to receive a rebar rod.

A rebar support chair having a chair body including a plurality of conjoined legs, the conjoined legs defining a receiving area and a foot affixed to at least one leg.

An adjustable concrete reinforcement assembly includes a base member having a pair of open ends and an upper axial cavity defined along the length of the base member. A pair of frame members each include a horizontal extending portion and a vertical extending portion in which the horizontal extending portions are sized to engage the upper axial cavity of the base member. A hanger member is disposed at an upper end of the vertical extending portions of each frame member; wherein the frame members are axially movable within the base member to enable a horizontal dimension of the assembly to be selectively adjusted. At least one support is further provided to receive at least one concrete reinforcement member, such as rebar. In at least one version, adjustments can be to the horizontal dimension of the frame and optionally the vertical and horizontal positioning of the hanger members relative to a concrete form.

A shear connector for use with insulated concrete panels. The shear connector comprises an elongated core member that includes a first end and a second end, and a flanged end-piece removably secured to one of the first end or the second end of the core member. At least a portion of the flanged end-piece includes a maximum diameter that is larger than a maximum diameter of the core member. The shear connector is configured to transfer shear forces.

A system including an insert including a body defining an inner cavity at a first end thereof. The insert includes an anchor having an opening formed therein, and the opening of the anchor is positioned in the inner cavity of the insert. The system further includes a spacer having a first end that is couplable to a second end of the insert to thereby adjust a height of the insert. The spacer is configured to be coupled to another spacer at a second end of the spacer.

A fixture for setting rebar at a predetermined distance from the rim of an excavated pit includes elongated first and second legs each having a proximal end and a distal end, the first and second legs rigidly joined at their mutual proximal ends to form an L-shape; an angle adjustment device carried by the first leg, comprising a foot movable towards or away from the first leg along an axis generally parallel to the second leg; a support bracket carried by the first leg at a predetermined offset distance from the proximal end thereof; and a hook extending from the distal end of the second leg, generally parallel to the first leg.
