Abstract

A method for manufacturing a shell element reinforced with support elements comprises providing a skin element that has an outer surface and an inner surface opposite the outer surface, providing a first support element that has an attaching side and a free side opposite the attaching side, attaching the first support element on the skin element such that the attaching side of the first support element faces the inner surface of the skin element. A first recess is introduced into the first support element that proceeds from the free side of the first support element and extends transversely to the first axis. A second support element is provided that has a support side and a front side opposite the support side. The second support element is inserted into the first recess of the first support element such that the support side faces the inner surface of the skin element.

Dependent claims

A method for manufacturing a shell element reinforced with support elements, having the following steps of:

(a) providing a skin element that has an outer surface and an inner surface disposed opposite the outer surface;
(b) providing a first support element that extends along a first axis and has an attaching side that is parallel to the first axis, and a free side opposite the attaching side;
(c) attaching the first support element on the skin element such that the attaching side of the first support element faces the inner surface of the skin element;
(d) forming a first recess on the first support element, which proceeds from the free side of the first support element and extends transversely to the first axis;
(e) providing a second support element that extends along a second axis and has a support side that is parallel to the second axis, and a front side opposite the support side;
(f) inserting the second support element into the first recess of the first support element such that the support side faces the inner surface of the skin element, and such that the second axis of the second support element extends transversely to the first axis of the first support element;
and
(g) attaching the second support element on the first support element and/or on the skin element;
wherein a projection is provided on the first support element, the projection extending on the free side away from the skin element;
wherein the first recess is formed in the projection;
and
wherein the projection is formed by removing material from the first support element, on the free side thereof, on both sides of the first recess and at a distance from the first recess.
