A method for connecting two sandwich plate elements by means of a connection element, each sandwich plate element comprising a plate core and a first and second plate skin,
- wherein the first and second plate skin are made from a fibre-reinforced polymer material or from metal, wherein the first plate skin is arranged to at least partly cover a first major surface of the plate core, thereby forming a first major outer surface of the sandwich plate element, and
- wherein the second plate skin is arranged to at least partially cover a second major surface of the plate core thereby forming a second major outer surface of the sandwich plate element,
- the connection element defining two recesses,
- wherein each recess comprises a first and a second inner surface and is configured to hold an edge portion of one of the two sandwich plate elements such that at least a portion of the first major outer surface of the sandwich plate element interacts with the first inner surface of the recess and at least a portion of the second major outer surface of the sandwich plate element interacts with the second inner surface of the recess,
- wherein the connection element comprising a first part and a second part which are connectable to each other by means of a snap fit joint comprising interlocking features wherein the first part and the second part are locked by mechanical engagement from being separated with respect to each other when the second part is connected to the first part for formation of at least one of said two recesses, in which the first inner surface is arranged on the first part and in which the second inner surface is arranged on the second part,
- wherein the interlocking feature of the first part is formed by at least one first hooking flange having a first hook portion, the at least one first hooking flange extending from the first part,
- the interlocking feature of the second part is formed by at least one second hooking flange having a second hook portion, the at least one second hooking flange extending from the second part,
- wherein the first hook portion of the at least one first hooking flange engages behind the second hook portion of the respective at least one second hooking flange, and
- wherein the first and/or second part of the connection element comprises a stop configured to restrict a motion of the first part of the connection element in relation to the second part of the connection element in a direction of connecting the snap fit joint;
- the method comprising:
- applying an adhesive to the first and second inner surfaces arranged on the first and second part and to the portion of the first outer major surface and to the portion of the second outer major surface of the sandwich plate element associated with the at least one of said two recesses,
- arranging, subsequent to applying the adhesive, the portion of the first outer major surface in contact with the first inner surface arranged on the first part, and
- connecting the second part to the first part by means of the snap fit joint for formation of the at least one of said two recesses, whereby the portion of the second outer major surface is brought in contact with the second inner surface arranged on the second part, such that the at least one recess, holds the edge portion of the sandwich plate element associated therewith, thereby connecting said two sandwich plate elements, via the connection element, by means of an adhesive joint.
