## Abstract

A device and to a method for the production of essentially two-dimensionally arched large-area structural components from a fiber composite material, including a jig having a convex mounting surface which has longitudinally extending receiving channels for the insertion of construction components and which can be loaded with auxiliary materials, wherein the loaded jig interacts with a laminating bonding device having a corresponding shape for forming the structural component under pressure, wherein the jig includes a mounting shell that at the edge can be elastically deformed inwards, which mounting shell, by way of a plurality of actuators that are articulated to the inside, can be moved between an extended position (A) and at least one retracted position (B) in which the jig can be moved relative to the longitudinally extending receiving channels from the laminating bonding device without undercuts.

## Claims

### Claim 1

A device for the production of essentially two-dimensionally arched large-area structural components from a fiber composite material, comprising:
a jig having a convex mounting surface comprising a plurality of receiving channels for the insertion of construction components and configured to be loaded with auxiliary materials,
wherein the loaded jig is configured to interact with a laminating bonding device having a corresponding shape for forming the structural component under pressure,
wherein the jig comprises a mounting shell configured to be elastically deformed inwards at the edge thereof, and
a plurality of actuators articulated to the inside and configured to move the mounting shell between an extended position (A) and at least one retracted position (B),
wherein, in the at least one retracted position, the jig is configured to be moved relative to the receiving channels from the laminating bonding device without undercuts,
wherein the actuators are arranged spaced apart from each other along first and second opposing edge regions of the mounting shell for enabling the mounting shell to move between the extended position (A) and the at least one retracted position (B), and
wherein the mounting shell consists of one arched metal sheet.

### Claim 2 (depends on 1)

The device of claim 1, wherein the longitudinal extension of the actuators is aligned so as to point inwards, and said actuators are articulated in the interior to a stationary supporting structure.

### Claim 3 (depends on 1)

The device of claim 1, wherein the actuators comprise pneumatic cylinders or linear electrical drives.

### Claim 4 (depends on 1)

The device of claim 1, wherein the mounting shell is in the shape of a cylinder segment.

### Claim 5 (depends on 1)

The device of claim 1, wherein the receiving channels for the stringers are formed into the mounting shell.

### Claim 6 (depends on 1)

The device of claim 1, wherein the supporting structure of the mounting shell comprises a plurality of framework beams.
