Abstract
A method for the manufacture of a foldable building plate element by providing a flat plate (1), providing of at least one folding groove (2) in the flat plate, providing a folding profile (6), comprising two side wings (7) and an interposed folding portion (8), and fitting the folding groove into the folding profile in such a way, for example by gluing, that the side wings thereof form a strong connection with the two side faces (5) of the folding groove. The side wings are interconnected with each other through a bridging strip (9), which will be removed when the plate is folded. The wings are further provided with connecting means (10) that snap-connect with each other when the side wings are folded towards each other. If desired, a filler strip (11) can be inserted between the side wings.
Claims2
A profile, arranged to be used as a folding profile, the profile comprising;
- two side wings (7, 7a) and an interposed folding portion (8) in cross sectional view, wherein the side wings are arranged to form a strong connection with both side faces of a folding groove (2) and/or with zones of a flat plate (1) located adjacent to the folding groove;
- wherein the side wings of the folding profile are provided with connecting means (10), which are arranged to detachably interconnect, when the side wings are folded towards each other;
- wherein the connecting means (10) on the side wings are mutually snap-connectable when the side wines are folded towards each other;
- wherein during transport or storage of the flat plate (1) the side wings of the folding profile are interconnected by means of a removable bridging strip (9) to maintain the folding profile in an open position, the bridging strip (9) comprises connecting means (13), the connecting means (13) on the bridging strip are snap-connectable and snap-detachable,
- wherein the connecting means (13) on the bridging strip (9) are the same as the connecting means (10) on the side wings of the folding profile, so that in the open position of the side wings, the snap-connectable means (13) of the bridging strip are snap-connected to the snap-connectable means (10) on both side wings of the profile.
