Abstract
The invention relates to a panel structure, in which structure at least two layer sheets (1,6;12,13;22,23;31,32;41,44,45) are fixed to each other with at least one connection member (2,11,21,33,42,43,46) and the connection member (2,11,21,33,42,43,46) is generated from one of the at least two layer sheets (1,6;12,13;22,23;31,32;41,44,45). At least part of the connection member (2,11,21,33,42,43,46) is diverged from the layer sheets (1,6;12,13;22,23; 31,32;41,44,45) forming at least one opening (8,17,27,35) through the layer sheet (1,6;12,13;22,23;31,32;41,44,45) wherefrom the connection (2,11,21,33, 42,43,46) is generated.
Claims20
A panel structure comprising at least first and second layer sheets each comprising a main sheet portion, wherein at least the first layer sheet is made of metal and comprises a plurality of elongate connection members that diverge from the main sheet portion of the first layer sheet and form openings through the main sheet portion of the first layer sheet, each of said connection members has a first end that is proximal to the main sheet portion of the first layer sheet and at which the connection member is attached to the main sheet portion of the first layer sheet and an opposite second end portion that is distal from the main sheet portion of the first layer sheet, said connection member is directly fixed at its second end portion to the main sheet portion of the second layer sheet, and the first layer sheet comprises a single connection member for each opening through the main sheet portion of the first layer sheet.
A panel structure comprising at least first, second and third layer sheets each comprising a main sheet portion, wherein the second layer sheet is disposed between the first and third layer sheets, at least the third layer sheet comprises first and second pluralities of elongate connection members that diverge from the main sheet portion of the third layer sheet and form openings through the main sheet portion of the third layer sheet, each of said connection members has a first end that is proximal to the main sheet portion of the third layer sheet and at which the connection member is attached to the main sheet portion of the third layer sheet and an opposite second end portion that is distal from the main sheet portion of the third layer sheet, each connection member of the first plurality is fixed at its second end portion to the main sheet portion of the first layer sheet, and each connection member of the second plurality is fixed at its second end portion to the main sheet portion of the second layer sheet.
A panel structure comprising at least first and second layer sheets each comprising a main sheet portion,
- wherein the first and second layer sheets each comprise a plurality of elongate connection members that diverge from the main sheet portion of the respective layer sheet and form openings through the main sheet portion of the respective layer sheet,
- each of said connection members of the first layer sheet has a first end that is proximal to the main sheet portion of the first layer sheet and at which the connection member is attached to the main sheet portion of the first layer sheet and an opposite second end portion that is distal from the main sheet portion of the first layer sheet,
- said connection member of the first layer sheet is directly fixed at its second end portion to the main sheet portion of the second layer sheet,
- each of said connection members of the second layer sheet has a first end that is proximal to the main sheet portion of the second layer sheet and at which the connection member is attached to the main sheet portion of the second layer sheet and an opposite second end portion that is distal from the main sheet portion of the second layer sheet,
- said connection member of the second layer sheet is directly fixed at its second end portion to the main sheet portion of the first layer sheet,
- each of said connection members of the second layer sheet comprises an intermediate portion between its first end and its second end portion,
- the intermediate portion of each such connection member is oblique to the main sheet portion of the second layer sheet, and
- the second end portion of each such connection member is parallel to and directly fixed to the main sheet portion of the first layer sheet.
