Abstract
A thin wall system for providing a channel includes a plurality of planar basic parts for forming planar wall parts of the system, and a plurality of arcuate basic parts. The arcuate basic parts extend in a longitudinal direction and curve in a transverse direction for forming arched wall parts of the system. The arched wall parts are attached to the planar wall parts along their edges in the longitudinal direction for forming straight segments of the channel which includes rounded corners provided by the arched wall parts.

A thin wall system for providing a channel, comprising:
- a plurality of planar basic parts for forming planar wall parts of said system,
- a plurality of arcuate basic parts which extend in a longitudinal direction and curve in a transverse direction for forming arched wall parts of said system, said arched wall parts being attached to said planar wall parts along their edges in the longitudinal direction for forming straight segments of said channel which includes rounded corners provided by said arched wall parts, and
- at least one corner piece for joining two straight segments of said channel at an angle with each other, said at least one corner piece comprising:
- said planar basic parts attached to said arcuate basic parts to form walls, and
- curved basic pieces attached to said planar and arcuate basic parts to form corners in said corner piece.
A method of manufacturing a thin wall channel system, comprising:
- combining a multiple of planar basic parts to form planar wall parts of said system,
- combining a multiple of arcuate bask parts which extend in a longitudinal direction and curve in a transverse direction to form arched wall parts of said system,
- attaching said arched wall parts to said planar wall parts along edges in the longitudinal direction to form straight segments of a channel which includes rounded corners provided by said arched wall parts, and
- joining two straight segments at an angle with each other via a corner piece by attaching said planar basic parts to said arcuate basic parts to form walls in said corner piece and by attaching curved basic pieces to said planar basic parts and said arcuate basic parts to form corners in said corner piece.
A thin-walled channel system with rounded corners comprising:
- first basic parts having planar shape,
- second basic parts having cylindrical shape and arched cross-section,
- straight channel elements of the channel system formed by joining together said first and second basic parts along their longitudinal edges to provide straight channel elements having a cross-section with rounded corners formed by the arched cross-section of the second basic parts, and
- corner pieces for accomplishing a joint between at least two of said straight channel elements having deviating longitudinal directions, each corner piece comprising:
- first basic parts having planar shape,
- second basic parts having cylindrical shape and arched cross-section,
- and third and fourth basic parts having substantially curved shape,
- said corner piece having corners and being formed by joining the first and second basic parts together at their edges and by joining the third and fourth basic parts to at least some of the corners of the corner piece.
