Abstract

A construction kit for a housing structure of a monument for a cabin of a vehicle, in particular of an aircraft includes a plurality of integrally formed sandwich panels which each have two cover panels, which surround a core, and are formed with panel connecting structures which are each formed as a plug region or as a mating plug region. The mating plug region is formed so as to be complementary to the plug region in such a way that a plug region of a sandwich panel can be plugged into the mating plug region of another sandwich panel to connect the sandwich panels.

First claim

1 . A construction kit for a housing structure of a monument for a cabin of a vehicle, the kit comprising:
a plurality of integrally formed sandwich panels, each of the sandwich panels having a first and a second cover panel surrounding a core, and formed with panel connecting structures, each of the panel connecting structures formed as a plug region or as a mating plug region, wherein the mating plug region is formed to be complementary to the plug region such that a plug region of a first sandwich panel is configured to be plugged into the mating plug region of a second sandwich panel to connect the first and second sandwich panels.

2 . The construction kit of claim 1 , wherein the core of the sandwich panels comprise at least one of reinforcement fibres and layers of reinforcement fibres, the density distribution of the reinforcement fibres is increased at at least one of the plug regions and the mating plug regions.

3 . The construction kit of claim 1 , wherein the core of the sandwich panels include elongate hollow spaces, each of the hollow spaces extending through the core in a direction substantially parallel to the first and second cover panels.

4 . The construction kit of claim 1 , wherein at least two of the sandwich panels are formed integrally with one another so as to form a monument component.

5 . The construction kit of claim 1 , wherein the construction kit further comprises:
at least one fastening rail having a receiving space extending along the longitudinal direction of the fastening rail, the receiving space being configured to receive and fasten mounting feet of fixing elements to the fastening rail to fix the monument in position inside the cabin, wherein the fastening rail is formed with rail-to-panel connecting structures, each of the rail-to-panel connecting structures formed as a plug region or as a mating plug region, and wherein the mating plug region of the fastening rail is formed to be complementary to the plug region of the sandwich panels, and the plug region of the fastening rail is formed to be complementary to the mating plug region of the sandwich panels, so that the fastening rail is configured to be plugged together with sandwich panels.

6 . The construction kit of claim 5 , wherein the fastening rail is formed with a plurality of regularly spaced holes in the receiving space, the holes being configured to receive and fasten mounting feet of fixing elements to the fastening rail.

7 . The construction kit of claim 5 , wherein the fastening rail is in the form of a seat rail.

8 . The construction kit of claim 5 , wherein the fastening rail is formed substantially from fibre-reinforced plastics material, and at least two of the sandwich panels are formed integrally together with the fastening rails located therebetween to form a monument component.

9 . A monument for a cabin of a vehicle comprising a housing structure which is formed with a construction kit, the construction kit comprising:
a plurality of integrally formed sandwich panels, each of the sandwich panels having a first and a second cover panel surrounding a core, and formed with panel connecting structures, each of the panel connecting structures formed as a plug region or as a mating plug region, wherein the mating plug region is formed to be complementary to the plug region such that a plug region of a first sandwich panel is configured to be plugged into the mating plug region of a second sandwich panel to connect the first and second sandwich panels.

10 . An aircraft or spacecraft, comprising:
a cabin; a monument comprising a housing structure formed with a construction kit comprising:
a plurality of integrally formed sandwich panels, each of the sandwich panels having a first and a second cover panel surrounding a core, and formed with panel connecting structures, each of the panel connecting structures formed as a plug region or as a mating plug region;
at least one fastening rail having a receiving space extending along the longitudinal direction of the fastening rail, the receiving space being configured to receive and fasten mounting feet of fixing elements to the fastening rail to fix the monument in position inside the cabin, and
a fixing element connected to a structure of the aircraft or spacecraft and having mounting feet mounted at a distance from one another in the fastening rail of the monument, and the fixing element configured to fix the monument in a position inside the cabin,
wherein the mating plug region is formed to be complementary to the plug region such that a plug region of a first sandwich panel is configured to be plugged into the mating plug region of a second sandwich panel to connect the first and second sandwich panels, wherein the fastening rail is formed with rail-to-panel connecting structures, each of the rail-to-panel connecting structures formed as a plug region or as a mating plug region, and wherein the mating plug region of the fastening rail is formed to be complementary to the plug region of the sandwich panels, and the plug region of the fastening rail is formed to be complementary to the mating plug region of the sandwich panels, so that the fastening rail is configured to be plugged together with sandwich panels.

11 . A method for producing a construction kit for the housing structure of a monument for a cabin of a vehicle, the method comprising:
arranging two cover panels made of fibre composite semi-finished products around a core made of a foam to form a sandwich structure; inserting prefabricated panel connecting structures made of fibre composite semi-finished products in the sandwich structure to form plug regions or mating plug regions; impregnating the sandwich structure with a synthetic resin; and curing the sandwich structure impregnated with synthetic resin and forming a sandwich panel.

12 . The method of claim 11 , wherein the method further comprises plugging together a plurality of sandwich structures via the plug regions and the mating plug regions, and
wherein the curing of the sandwich structures impregnated with synthetic resin and plugged together comprises forming an integral monument component.

13 . The method of claim 11 , wherein the step of plugging together comprises introducing a fastening rail made of a fibre composite semi-finished product having prefabricated rail-to-panel connecting structures, the pre-fabricated rail-to-panel connecting structures forming plug regions or mating plug regions, and plugging together the fastening rail with sandwich structures.

14 . The method of claim 11 , wherein the step of arranging comprises at least one of sewing up the core with a plurality of reinforcement fibres and introducing a plurality of layers of reinforcement fibres, and
wherein a density distribution of the reinforcement fibres in the core is increased at at least one of the plug regions and the mating plug regions.

15 . The method of claim 11 , wherein the step of arranging comprises forming elongate hollow spaces in the core of the sandwich structures, the hollow spaces each extending through the core in a direction substantially parallel to the cover plates.
