Edge strip for mounting of a wall board

1. An edge strip configured to be attached to a wall structure for the mounting of a wall board against the a wall structure, the edge strip being composed of an elongated element suitable for length adaption through cutting in a length dimension to an extension of the wall structure in a specific dimension, the edge strip comprising:

a connection part arranged in a first side extending in the length dimension and is configured to be connected to a connection means integrated into the wall board, which connection means extends along a first side of the wall board, such that the wall board is attached to the wall structure, the connection part comprising click-in means configured to receive the connection means of the wall board and interconnect the wall board and the edge strip, such that the wall board becomes attached to the wall structure, and

an adaption part arranged in a second side opposite to the first side, which adaption part extends in the length dimension and is configured to contact against a flat building element of the wall structure,

a third side and a fourth side both extending in the length dimension and being mutually opposite to one another, and wherein the adaption part consists of a flat side surface that intersects both the third and fourth sides and has a first angle of 45 degrees relative to the third side and a second angle of 135 degrees relative to the fourth side.

2. The edge strip according to claim 1 , wherein said connection means of the wall board comprises a projection and said click-in means comprises a groove configured to receive the projection of said connection means.

3. The edge strip according to claim 2 , wherein the groove in said click-in means comprises:

a first tongue configured to be fitted against the wall structure and connected thereto using fastening means, and

a second tongue spaced apart from the first tongue and configured to mate with the projection of said connection means.

4. The edge strip according to claim 2 , wherein the groove in said click-in means has a curved cross section profile configured to receive the projection of the fastening means while the wall board is being angled in against the wall structure.

5. The edge strip according to claim 1 , wherein the edge strip is a first edge strip and its adaption part is configured to be attached on a primary side of a right-angled outer corner in the wall structure and there cooperate with the adaption part of a second edge strip being attached on a secondary side of the right-angled outer corner such that the edge strips by contacting between the respective adaption parts together form a corner element starting from which wall boards may be attached to the wall structure along the primary side and the secondary side respectively.

6. The edge strip according to claim 5 , wherein the adaption part's flat surface in the first and second edge strip respectively is configured to receive a joining plate for fixating the first edge strip relative to the second edge strip.

7. The edge strip according to claim 1 , wherein the edge strip has a thickness in a dimension perpendicular to the length dimension, which thickness is in accordance with a thickness of the wall board, such that the wall board after being fastened against the wall structure by means of the edge strip forms a flat surface together with the edge strip.
