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.

The invention relates to a formwork module for a formwork for a building part comprising at least one formwork carrier and at least one formwork shell, wherein at least one connector is situated between the formwork carrier and the formwork shell. The connector comprises at least one carrier element which is fastened on or in the formwork carrier, and at least one formwork shell element which is fastened in or on the formwork shell. The carrier element and the formwork shell element can be reversibly interconnected and form the connector by means of which the formwork shell can be reversibly connected to the formwork carrier. The invention also relates to the use of a connector for detachably connecting a formwork carrier to a formwork shell and to a method for connecting a formwork shell to a formwork carrier of a formwork module. Finally, the invention relates to a method for separating a formwork shell from a formwork carrier of a formwork module.

Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other and a cross tie having opposed first and second ends, where at least the first sidewall is a removable sidewall removably secured to the first end of the cross tie. The second sidewall is removably secured to the second end of the cross tie and may be a removable sidewall or a non-removable sidewall. The concrete form also includes a spacer positioned between the first sidewall and the first end of the cross tie. The spacer may be removable along with the first sidewall. Concrete forming assemblies and methods may incorporate concrete forms as described herein.

The 2×4 Coupling Plate allows two boards to be reversibly coupled so that the lengths of the two boards may be added together. The coupling plates allows both boards to be separated without damaging them. This device allows a concrete fabricator to assembly two 2×4 boards together and hold them together to form a structure to contain liquid concrete. Once the concrete is set, the installer removes the two boards from the coupling plate so that the boards can be used on another concrete form.
