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) is—preferably detachably—coupled 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.
