Abstract

A formwork module for a formwork for a building part comprising at least one formwork carrier and at least one formwork shell, wherein at least one connector is situated between the formwork carrier and the formwork shell. The connector comprises at least one carrier element which is fastened on or in the formwork carrier, and at least one formwork shell element which is fastened in or on the formwork shell. The carrier element and the formwork shell element can be reversibly interconnected and form the connector by means of which the formwork shell can be reversibly connected to the formwork carrier. The use of a connector for detachably connecting a formwork carrier to a formwork shell and to a method for connecting a formwork shell to a formwork carrier of a formwork module. A method for separating a formwork shell from a formwork carrier of a formwork module.

First claim

The invention claimed is:

1. A formwork module for a formwork for a building part, comprising
at least one formwork carrier,
and at least one formwork shell,
wherein at least one connector is situated between the at least one formwork carrier and the at least one formwork shell, and the at least one connector comprises at least one carrier element which is fastened on or in the at least one formwork carrier, and at least one formwork shell element which is fastened in or on the at least one formwork shell;
and the carrier element and the at least one formwork shell element can be reversibly interconnected and form the at least one connector by means of which the at least one formwork shell can be reversibly connected to the at least one formwork carrier,
wherein the reversible connection between the at least one carrier element and the at least one formwork shell element is separable by applying a force in the normal direction to the at least one formwork shell directed away from the at least one formwork carrier which is larger than a threshold separation force, and connectable by applying a force in the normal direction to the at least one formwork shell directed towards the at least one formwork carrier which is larger than a threshold connecting force,
wherein the at least one formwork shell element includes a formwork shell attachment portion which is connected to the at least one formwork shell, and the connection between the at least one formwork shell element and at least one formwork shell is configured to be detachable, wherein a formwork shell adapter is disposed between the at least one formwork shell element and the at least one formwork shell, wherein the formwork shell adapter is a component which facilitates detaching and connecting the at least one formwork shell element from or to the at least one formwork shell, and the formwork shell adapter remains on or in the at least one formwork shell when the at least one formwork shell element is exchanged.

2. The formwork module according to claim 1 , wherein the at least one formwork shell element comprises a plurality of formwork shell elements, the plurality of formwork shell elements being disposed on a mounting side of the at least one formwork shell, and the at least one carrier element comprises a plurality of carrier elements, the plurality of carrier elements being disposed on a side of the at least one formwork carrier facing the at least one formwork shell, and in that, therefore, the at least one connector comprises a plurality of connectors, wherein the plurality of connectors are unevenly distributed across the at least one formwork shell and the at least one formwork carrier, wherein a higher number of the plurality of connectors per surface area is situated in a peripheral portion and/or at edges than in a central area of the at least one formwork shell and the at least one formwork carrier and/or wherein the plurality of connectors have different threshold separation forces, and a first subset of the plurality of connectors having higher threshold separation forces are located in the peripheral portion and/or at the edges, and a second subset of the plurality of connectors having lower threshold separation forces are located in the central area of the at least one formwork shell and the at least one formwork carrier, wherein, the plurality of connectors are based on the same or different operating principles.

3. The formwork module according to claim 1 , wherein the at least one carrier element is formed by a section of the at least one formwork carrier, wherein, the at least one carrier element is formed by a recess in the at least one formwork carrier.

4. The formwork module according to claim 1 , wherein the formwork shell adapter is form-closed connected to the at least one formwork shell, and the at least one formwork shell has a concrete side which faces the building part to be constructed in use of the formwork module, and the at least one formwork shell has a mounting side located opposite of the concrete side which faces the at least one formwork carrier, wherein the at least one formwork shell element and the formwork shell adapter are disposed on or in the mounting side, wherein the formwork shell adapter is insertable into the at least one formwork shell on the mounting side of the at least one formwork shell by a movement parallel to the mounting side of the at least one formwork shell, and, in the state inserted into the at least one formwork shell, there is a form-closed connection between the at least one formwork shell and the formwork shell adapter in a direction perpendicular to the mounting side, wherein the at least one formwork shell, in a side view from a direction perpendicular to the mounting side, has a recess having an undercut, and the formwork shell adapter is inserted into the recess, wherein a section of the formwork shell adapter is disposed in the undercut of the recess, and thus a form-closed connection between the at least one formwork shell and the formwork shell adapter is provided in a direction perpendicular to the mounting side.

5. The formwork module ( 1 ) according to claim 1 , wherein the at least one formwork shell, in a plan view of a mounting side, has a recess having defining walls extending perpendicular to the mounting side, and the formwork shell adapter is pressed into the recess in a direction perpendicular to the mounting side, wherein at least a section of the formwork shell adapter is positioned in the recess, and thus a force-fit connection is provided between the at least one formwork shell and the formwork shell adapter in a plane parallel to the mounting side.

6. The formwork module according to claim 1 , wherein the formwork shell adapter has a recess having an undercut into which the at least one formwork shell element is reversibly insertable, wherein this reversible connection of the at least one formwork shell element to the formwork shell adapter is at least partly established by a form-closed connection of a section of the at least one formwork shell element to the undercut of the recess in the formwork shell adapter, and the form-closed connection between the at least one formwork shell element and the formwork shell adapter can be established and released by a linear movement of the at least one formwork shell element relative to the formwork shell adapter in a direction parallel to a mounting side, or the form-closed connection between the at least one formwork shell element and the formwork shell adapter can be established and released by a rotating movement of the at least one formwork shell element relative to the formwork shell adapter about a rotational axis oriented perpendicular to the mounting side.

7. The formwork module according to claim 1 , wherein the at least a one formwork shell element includes a shaft and a connector head, wherein the at least one formwork shell element is connected to the at least one formwork shell at one end of the shaft, and the connector head is connected to the one end of the shaft located opposite of the at least one formwork shell, and the connector head has at least one bending portion which is elastically deformable relative to the shaft.

8. The formwork module according to claim 7 , wherein the at least one bending portion has at least one insertion surface and at least one separation surface, wherein, when the at least one formwork shell element is connected to the at least one carrier element, the at least one insertion surface, at least in sections, abuts on the at least one carrier element, and, when the connection of the at least one formwork shell element to the at least one carrier element is released, the at least one separation surface, at least in sections, abuts on the at least
