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 support structure for a frame formwork panel including a support structure and a formwork skin connected to the support structure, the support structure having two longitudinal edge girders and two transverse edge girders, wherein a corner connecting piece which is welded to the two respective edge girders is provided in at least some of the corner regions of the support structure where a longitudinal edge girder and a transverse edge girder come together.

A support structure for a formwork panel having a support structure and a formwork skin positioned on the front of the support structure and attached to the support structure, wherein the support structure has at least one edge girder on a pair of opposite edges and a plurality of transverse girders between these two edge girders which run transversely to these two edge girders, characterized in that at least some of the transverse girders are designed as a profile girder, comprising a flange at its first end arranged at the front of the support structure, a tubular hollow section at its second end away from the front of the support structure, and between them a preferably wall-like member connecting the first end and the second end.

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 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 concrete formwork construction having a formwork element (1) whose frame (3) is produced from flat steel, whereas the struts (4) of the formwork element (1) are formed of sectional steel.
