Method to joggle a structural element and structural element joggled according to this method
View Patent ↗A joggled structural element includes two wings with a small thickness and a great thickness. Slopes made in a joggle of the structural element are computed as a function of each of the thicknesses of the wings. Thus, the joggled structural element comprises a shallow slope in the joggle on the side having the wing of great thickness and a steep slope in the joggle on the side having the wing of small thickness. A method is also disclosed implementing an anvil and a punch. This method can be used to make joggled structural elements.
1. A structural clement having two wings and a strut, a first wing, whose plane forms a non-zero angle with a plane of the strut, having a first thickness, and a second wing, whose plane forms a non-zero angle with a plane of the strut, having a second thickness less than the first thickness, the structural element formed with a linking joggle arranged between a first part and a second part of the structural element, the joggle giving an offset between the first part and the second part, the offset extending in the plane of the strut of the structural section with a height measured along a direction perpendicular to the plane of the wings and with a length measured in a direction parallel to the planes of the strut and the wings, the structural element comprising:
a shallow slope in the joggle of a side having the first wing, and a steep slope in the joggle of a side having the second wing.
2. A joggled structural element according to claim 1 , wherein projections of ends of the linking joggle on the steep-sloped side are arranged between projections of ends of the linking joggle on the shallow-sloped side.
3. A joggled structural element according to claim 1 , wherein a projection of an end of the joggle on the steep-sloped side is indistinguishable from a projection of an end of the joggle on the shallow-sloped side.
4. A joggled structural element according to claim 1 , wherein:
the steep-sloped joggle on the side having the second wing extends between the first and second parts on a length equal to about six times the second thickness, and
the shallow-sloped joggle on the side having the first wing extends between the first and second pans on a length equal to about six times the first thickness.
