An apparatus for forming a concrete column is disclosed. The apparatus may include a first column form half and a second column form half, which may be designed to be fitted together. The apparatus may also include a fastening system having at least one brace and a plurality of straps to fasten the first column form half with the second column form half to form a full column form. The full column form may then be filled with a poured concrete mixture, which when hardened or cured, may be a concrete column used in any number of structural or design applications.

A clamp for formwork for vertical castings, comprising a first body and a second body adapted to be slidingly coupled to each other, the first body comprising an elongated element which is extended predominantly along a first axis and has a first jaw at a first end, the second body comprising a substantially hollow base portion which can be associated slidingly with the elongated element and has a second jaw, locking means being provided in order to mutually lock the first and second bodies so as to mutually clamp two or more components between the first and second jaws.

A device for the positioning and retention of a tension member within a profile of a formwork panel. The device comprises a first tubular body adapted to be inserted within a through hole provided on the profile of the formwork panel, the first body having a wider abutment portion arranged at one of its ends, the wider portion being adapted to be in contact with the surface of the formwork panel that is directed toward the outside of the formwork.

A turnbuckle-style support strut with tunable stiffness, wherein the turnbuckle-style support strut uses opposing stacks comprised of one or more Belleville spring washers to provide the tunable stiffness to support a given application.

A method for repairing a multi-sided structure protruding from a first surface. The method comprises mounting a retainer to the first surface, coupling a first brace connector component of a first brace to a first panel, coupling the first panel to a primary retainer connector component of the retainer, coupling a second brace connector component of the first brace to a secondary retainer connector component of the retainer, and introducing a curable material into the space between the first panel and the multi-sided structure, the first panel acting as at least a portion of a framework for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the first panel.

In a first aspect there is disclosed a support structure assembly (10). The support structure assembly includes a first wall panel (12) operatively associated with an opposing, spaced apart second wall panel. The first wall panel (12) including a channel (14) having two spaced apart channel walls (16) connected via a transverse channel base (18). The channel (14) encloses a resilient body (20).

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.
