A pyramid beam head , also Quedlinburg pyramid , is a form of beam heads used in the construction of half-timbered houses . The end of the beam protruding from the house is designed in the form of a pyramid that slopes down towards the viewer. This form of design occurred particularly in the city of Quedlinburg in the 17th and 18th centuries, but is also documented in other places such as Hedersleben .

Creation

The pyramid beam head is created by sawing off the wooden beam protruding from the building at right angles. The lower edge of the resulting cut surface is marked. The point marked in this way is connected to the corners at the top left and top right. A distance that corresponds to the height of the bar is marked to the rear on the underside of the bar. The resulting rear points on the left and right are connected to the originally marked middle point in front. Two tetrahedra are thus delimited to the left and right . They are each removed with one cut. What remains is the pyramid, which is inclined downwards forwards.

history

The first known use of pyramid beam heads took place in 1632 by master carpenter Wulf Götze at the half-timbered house Pölle 28 . In the Quedlinburg half-timbered building it was then the dominant design form of the beam heads for about 80 years. Before that, the shape of the cylinder beam head was common. First of all, the side surfaces of the pyramid were smoothed and processed, whereby the pyramid stood out clearly from the rest of the bar. Later this work was done without, so that the pyramid rises directly out of the wood. The predominant use of the pyramid beam heads ended around 1710. The last historical use of the design in Quedlinburg took place in 1734 at the Augustinern 22, 23 and An der Kunst 8 houses . In 1768, in the course of an expansion, Gildschaft 7 was again made use of pyramid beam heads.
