Abstract
A concrete ceiling element for producing a concrete ceiling is disclosed. The concrete ceiling element has a flat basic structure that has an upper side and at least one FRC plate. The concrete ceiling element has at least one FRC ridge. The FRC ridge is arranged on the upper side and connected in sections to the basic structure. Furthermore, a concrete ceiling and a method for producing a concrete ceiling or a concrete ceiling element are provided.
Claims54
A concrete ceiling element comprising:
- a flat basic structure with an upper side and comprising a FRC-plate;
- and
- a FRC ridge,
- wherein the FRC ridge is arranged on the upper side and connected in sections to the basic structure,
- wherein the FRC ridge has at least two supports which provide the connection to the basic structure in the sections, and
- wherein:
- at least one of the at least two supports at an end thereof and facing the upper side has at least one extension, which extension is arranged in a recess of the FRC-plate of the basic structure and is fixed in the recess which is dimensioned larger than the extension;
- or
- the FRC-plate of the basic structure has at least one extension on the upper side thereof, which extension is arranged in a recess at an end of at least one of the at least two supports of the FRC ridge and is fixed in this recess which is dimensioned larger than the extension.

A method for connecting two FRC concrete elements comprising the steps of:
- providing a plug-and-fit connection;
- and
- connecting the two FRC concrete elements with the plug-and-fit connection, wherein the plug-and-fit connection consists of an extension of one of the at least two FRC concrete elements that is inserted into a recess in another of the at least two FRC concrete elements, and a filling material, wherein the recess is dimensioned larger than the extension and the extension and recess are not dimensioned for a form fit, and wherein the extension is fitted into the recess by the filling material so that a non-positive connection of the plug-and-fit connection is only obtained by means of the filling material.
A method for producing a concrete ceiling, comprising:
- providing a FRC-plate having an upper side for forming a basic structure, wherein the FRC-plate has a recess on the upper side;
- arranging a FRC ridge having at least two supports on the upper side of the basic structure by introducing an extension of one of the at least two supports of the FRC ridge into the recess of the at least one FRC-plate, wherein the recess is dimensioned larger than the extension, and fixing the extension in the recess with the aid of a filling material;
- and
- supporting a cover layer on the FRC ridge.
