Dowel ceiling
A doweled ceiling (regionally also chaffed ceiling , southern German dippel ceiling or in the Thuringian region beam-beam ceiling ) is a massive historical ceiling construction.
Dipple trees (beams) that are hewn on three sides, i.e. semicircular and not cut at the crossing points, are directly lined up with the long side and, for better load distribution, 1–2 m apart and offset from one another with wooden pegs (hardwood dowels, approx. 2–3 cm thick and approx. 10 –15 cm long) or secured with metal straps. This distributes the load over several beams and prevents the ceiling from swinging too much. The ends of the Dippel trees were placed on a wall lath (also rest shop or rest lock ) on the building wall. In a second step, the ceiling beams are planed from below and then have a full-surface wood look. The embankment lies directly on the Dippel beam and above it the accessible floor. At the bottom may be at a pipework from reed (as a plaster base) of the plaster be attached.
This type of construction was widespread in Austria and southern Germany until around 1900 - it was also required in part for fire protection reasons - and was replaced by the lighter tram ceiling , which could be made with significantly less wood.
