Abstract: In one arrangement, shown in FIG. 1, there is provided a formwork restraint for a reinforcement bar. The formwork restraint includes a restraint portion for receiving the reinforcement bar. The formwork restraint further includes a support portion adapted to connect the restraint portion to a reinforcing formwork arrangement to maintain a desirable relationship between the reinforcement bar and the reinforcing formwork arrangement.

Abstract: A support member for a concrete structure comprises a Y-shaped hollow insert defining an internal channel having a Y-shaped cross-section. A V-shaped nut is inserted in V-shaped portion of the internal volume and end caps are placed over the ends of the insert to fully enclose the internal volume. The insert is then placed within a form for a concrete structure such that the base surface of the Y-shaped insert will be coplanar with a surface of the concrete after the concrete has been poured into the form and set. The base wall of the insert is then removed, thus exposing the internal volume. The distal end of a bolt can be inserted into the insert and fixed to the nut. The proximal end of the bolt extends out of the insert and beyond the surface of the concrete to be attached to equipment or another structure which is to be supported on the concrete structure.

Abstract: A support member for a concrete structure comprises a T-shaped insert defining a T-shaped internal volume. A nut is inserted in the transverse portion of the internal volume and end caps are placed over the ends of the insert to fully seal enclose the internal volume. The insert is then placed within a form for a concrete structure such that the base surface of the T-shaped insert will be coplanar with a surface of the concrete after the concrete has been poured into the form and set. The base wall of the insert is then removed, thus exposing the T-shaped volume. The distal end of a bolt can be inserted into the insert and fixed to the nut. The proximal end of the bolt extends out of the insert and beyond the surface of the concrete and can be attached to equipment or other structure which is to be supported on the concrete structure.

Abstract: An improved anchor for embedment in a concrete member to provide a lifting attachment for the member. The anchor comprises an elongate bar having convergent and divergent surfaces wherein the divergent surfaces face outwardly to direct axial pull-out forces imparted to the bar divergently and laterally into a concrete member within which the anchor is embedded. Divergent wings are fixed to and extend laterally from the bar to direct lateral forces imparted to the bar in divergent directions relative to the bar.

Abstract: An attachment for a conventional pry bar facilitates the bar for use in the pulling of stakes. The attachment comprises a section of pipe which is flattened to provide a tubular portion telescopically receivable over the end of a pry bar and thin edge portion to one side of the tubular portion. The edge portion is formed with a notch proportioned for slidable receipt around a stake to be pulled and gripping engagement with the stake upon cocking of the attachment relative to the stake. In use the stake is cocked for gripping and pulling engagement with the stake by fulcruming the pry bar against a surface adjacent the stake.
