Fluting (architecture)

The fluting (Latin canna = pipe; French = cannelure groove, groove, groove) is the groove of an object, usually a pillar, a pier or a pilaster with vertical concave grooves. It is mainly found in the ancient and standing in the tradition of architecture. As a decorative motif, they have also been adopted in furniture, handicrafts and metal processing.

The fluting is used for optical structuring of the shaft, the emphasis on the Aufstrebens the column and to transfer the horizontal joints between the individual column drums - so let the shaft monolithic appearance. She has no constructional function.

Doric columns usually have 20 flat fluting, which blend into ridges, therefore also referred to Gratkannelierung. Ionic columns and Corinthian order, however, have - at least since the classical period - usually 24 flutings, the ( stria ) are separated by a narrow bridge. They are semi-circular in cross section and are also completed in the semi-circular upper and lower ends. Thus, the ends of which form the quarter of a sphere. In the Archaic period, however, Ionic columns had shallow fluting in varying numbers up to 48, which were separated by only a very narrow webs or sometimes even touched on how Doric columns in burrs.

Since the Hellenistic columns were sometimes fluted only above a certain height, referred to as part fluted columns or Teilkanneluren. At the bottom of the column shafts it can be smooth left or worked in facets that unlike fluting have the form of flat strips. In Roman architecture, the fluting on the lower part of the column shaft are sometimes filled with narrow rods, the so-called pipes in a similar way. This subdivision of the shaft, which runs counter to the original vertical stress, causes a horizontal layout of a column front.

A significant emphasis has the groove in the Gothic style. Gothic Portalgewände are often grooved. However, it does not speak here of " fluting ". The clustered columns - a typical gothic element - is basically a deep fluted single pillar.

In the metal processing (eg in gun barrels ), it serves to reduce weight with high stability ( bracing through the available remaining material ) and to increase the surface area for better heat dissipation.

In the scarf she used to fix the shaft to the fluted tip.
