A grid beam slab formwork comprising of primary beams, secondary beams, multi-level drophead unit, and props. The multi-level drophead unit offers up to or more than six connection points for the primary beams and the secondary beams. The multi-level drophead unit allows the construction of an additional structure that otherwise requires a separate drophead or an adaptor thereby reducing an overall cost associated with the formwork. Moreover, the multi-level drophead unit enables the creation of the platform wherever needed. On the other hand, the adapter prevents entrapment of the sheathing members, such that the beams can be removed when the concrete has achieved required strength and the load can be taken by the props.

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.

According to the invention a wall formwork (1, 2) for the production walls consisting of concrete having a coupling device (4, 10), by means of which the wall formwork (1, 2) may be coupled to another wall formwork which is arranged adjacent or above is provided. The coupling device (4, 10) ispreferably detachablycoupled to the wall formwork (1, 2) and is especially coupled to a supporting element (2) of the wall formwork (1, 2). By coupled it is meant that the coupling device (4, 10) may even kept coupled to the wall formwork (1, 2) when the coupling device (4, 10) will not be used for coupling the wall formwork (1, 2) to another wall formwork. By way of coupling between the coupling device (4, 10) and the wall formwork (1, 2), during installation, a coupling device (4, 10) will immediately be available, if the wall formwork (1, 2) is to be coupled to another wall formwork by the coupling device (4, 10). By this, assembling will be promoted. Also realization of disassembling may be promoted, since the coupling device (4, 10) does not have to be deposited nor handled separately. For disassembling detachment of the coupling device (4, 10) from the wall formwork (1, 2) which is arranged adjacent or above will be sufficient.

Various implementations described herein are directed to a bracket of a formwork system. In one implementation, the bracket includes: a first member having a first plurality of openings; and a second member having a second plurality of openings. The first member and the second member are configured to: be perpendicular to each other, and provide lateral adjustment via the first plurality of openings and/or the second plurality of openings.
