A hinged corner for a construction form includes a first flange connected to a first mounting plate for a form member and a second flange connected to a second mounting plate for a form member. The first flange and the second flange pivot relative to one another in an overlapping relationship about a pivot point disposed between the first mounting plate and the second mounting plate.

A corner shuttering element with two limbs arranged at an angle to each other, on the outer edge of which limbs, edge strips are arranged that can be retracted and extended by means of articulated levers, wherein the edge strips can each be aligned and fixed in their position by means of a plurality of locking elements arranged distributed over the height of the corner shuttering element, and wherein the locking elements are arranged on guides for pull-out webs of the edge strips.

Insert element for insertion into a cavity of a plastic formwork panel frame with a mounting for accommodating a read-out data memory.

A column forming system for creating chamfer corners and allowing efficient movement from one column location to the next. The column forming system comprises a plurality of formwork panels, a hinge corner bracket moveable between an open and a closed position, and a plurality of corner brackets. The connection of the components allows for the manipulation of the formwork panels relative to one another. A closed position of the hinge corner bracket results in the column forming system defining a column interior.

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.

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.

A string holder for use with concrete forms comprising a main body having a central portion and first and second wing type portions that are coupled to the central portion. The central portion includes a first axial arm extending in a first direction and a second axial arm extending in a second direction opposite to the first direction, wherein the first axial arm has formed thereon one or more grooves sized and dimensioned for accommodating a string. The first wing type portion and the second wing type portion are angled relative to the central portion and extend radially outwardly therefrom. Each of the wing type portions includes a radial arm and a further axial arm.

The system herein disclosed and claimed is a system for positioning and adjusting wooden concrete forms.

A system, comprising: at least one planar member having a two- or three-dimensional surface pattern formed thereon or therein; and a plurality of resilient spacers removably positionable on or in the surface pattern to form a surface relief pattern of spaced-apart recesses on the at least one planar member.
