Abstract

The disclosure relates to formwork for producing a concrete element, in particular a wall element or ceiling element, having an opening, in particular a window opening or door opening, the formwork comprising: a formwork panel; opening formwork, which has a frame element for delimiting a portion of the opening, a support bracket for supporting the frame element, and a mounting element for mounting the support bracket; a formwork-stripping device for transferring the opening formwork from a formwork position for the formation of the opening into a formwork-stripping position for the release of the concrete element, wherein the formwork-stripping device has a sliding and tilting mechanism for sliding the frame element in a direction parallel to the formwork panel and for tilting the frame element about a pivot axis running substantially parallel to the formwork panel.

Dependent claims

A formwork for the production of a concrete element with an opening comprising:

a formwork panel,
an opening formwork with a frame element to delimit a portion of the opening, with a support bracket for supporting the frame element and with a mounting element for mounting the support bracket, and
a formwork-stripping device for transferring the opening formwork from a formwork position to form the opening into a formwork-stripping position for releasing the concrete element,
wherein the formwork-stripping device comprises a sliding and tilting mechanism for sliding the frame element in one direction parallel to the formwork panel and for tilting the frame element about a pivot axis extending substantially parallel to the formwork panel,
wherein a securing element is provided for securing the support bracket in the formwork position, and
wherein the mounting element comprises at least one first wedge surface and the securing element comprises at least one second wedge surface, wherein in a secured state of the securing element the second wedge surface of the securing element rests on the first wedge surface of the mounting element.
