Method for producing a wall-ceiling reinforced concrete construction
Method of producing a wall-floor reinforced concrete construction in which use is made of prefabricated permanent shuttering systems made up of a wall shuttering system ( 100 ) with two shuttering panels ( 101; 103 ) and a floor shuttering system ( 120 ) which comprises a base plate ( 123 ) with a multiplicity of individual longitudinal bars ( 121 ) next to one another which are each fastened by means of a multiplicity of stirrups ( 122 ) on the base plate ( 123 ) at a distance above the base plate in such a way that they come to lie in the lower region of the floor ( 171 ) to be produced. The connecting element between the wall and floor that is used is a coupling reinforcement ( 150 ) which, on one side, is fastened into the wall shuttering system ( 100 ) and, on the other side, to the individual longitudinal bars ( 121 ) of the floor shuttering system ( 120 ) which extend perpendicularly to the wall shuttering system ( 100 ).
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.
2. The method according to claim 1 , wherein the ceiling and wall are grouted with concrete in one course starting from an upper side of the ceiling formwork.
3. The method according to claim 2 , wherein prefabricating and erecting the wall formwork system comprise providing that the first formwork panel is lower than the second formwork panel after erecting the wall formwork system, and attaching the ceiling formwork system on an upper portion of the wall formwork system further comprises placing the base panel of the ceiling formwork system flush onto the first formwork panel of the wall formwork system.
4. The method according to any one of claims 1 to 3 , wherein the concrete is a self-compacting concrete.
