The present disclosure relates to a formwork anchor receptacle for arrangement on a bearing element of a formwork element, having a receptacle element, which has a receptacle opening for insertion of an anchor rod and a ball section for mounting on the mounting element of the formwork element, and having a retaining apparatus for retaining the receptacle element on the bearing element of the formwork element, wherein the retaining apparatus has a spacer element for contacting the bearing element of the formwork element, wherein the spacer element has an mounting opening for mounting on the receptacle element and a formwork device having such a formwork anchor receptacle.

A method of forming one or more tie rods that includes flattening a main body of a wire in a first selected plane to form a flattened main body, further flattening selected portions of the flattened main body in a second plane perpendicular to the first plane to form one or more break back regions, and then passing the wire through a punch press machine to form one or more coined regions in one or more ends of the wire, thus forming the tie rod.

A modular form system for constructing insulated concrete walls comprises spaced apart vertical frame members which include retention structures allowing for the insertion of spaced-apart rows of insulated panels to form an internal cavity into which concrete may be poured. The retention structures may include flanges on the periphery of the frame members and plates positionable in opposition to the flanges. The insulated panels are retained between the flanges and the plates.

A system and method for positioning and retaining an internal rebar skeleton for a concrete wall prior to pouring uses spaced apart vertical frame members having horizontal structures onto which horizontally oriented rebar can be laid and modular rebar retainers for positioning vertically oriented rebar in relation to the horizontally oriented rebar. The frame members may also include retention structures allowing for the insertion of spaced-apart rows of insulated panels to form an internal cavity into which concrete may be poured. External cladding is affixed to an external flange or sheath on the frame members with a thickness that creates a desired air gap between the external cladding and insulated panels. Frame members may also be laid horizontally across the top of a vertical layer of panels to form a base for a successive layer of vertical frame members and panels.
