Abstract:
1. A method for producing a wall-ceiling reinforced concrete construction, the concrete construction comprising a wall and a ceiling, the wall including concrete between first and second formwork panels of a permanent wall formwork system, and the ceiling including a finished concrete layer on a base panel of a permanent ceiling formwork system, the finished concrete layer having a projected thickness, the method comprising: prefabricating the permanent wall formwork system, the permanent wall formwork system including the first and second formwork panels that are set apart from each other and secured to each other by coupling devices, prefabricating the permanent ceiling formwork system, the permanent ceiling formwork system including the base panel, a plurality of stirrups that are secured onto the base panel, and a plurality of individual longitudinal bars that are secured to the plurality of stirrups and are anchored by the plurality of stirrups, to the base panel side by side to extend in a distance above the base panel, so that the plurality of individual longitudinal bars lies in a lower third of said projected thickness of the finished concrete layer of the ceiling, erecting the prefabricated wall formwork system and attaching the prefabricated ceiling formwork system on an upper portion of the wall formwork system, so that the plurality of individual longitudinal bars and extends perpendicularly to the wall formwork system, thereafter inserting a first leg of an angular connection reinforcement in such a way downwards into the upper portion of the wall formwork system, that a second leg of the connection reinforcement is spaced in a distance above the plurality of individual longitudinal bars of the ceiling formwork system and in an upper region of said projected thickness of the finished concrete layer, anchoring the second leg of the connection reinforcement to the base panel of the ceiling formwork system by securing the second leg to at least one of the plurality of individual longitudinal bars, and, thereafter, grouting the ceiling and the wall with concrete.
