Hetzerhalle

Hetzerhallen are column-free halls with a roof structure made of glued laminated timber or laminated beams , which were named after the inventor of their roof or hall structure, the Grand Ducal Weimar court carpenter and entrepreneur Karl Friedrich Otto Hetzer (1846–1911).
The first Hetzerhalle with 43 m free span was designed by the architect Peter Behrens from Berlin on behalf of the German Reichsbahnen for the Brussels World Exhibition in 1910 , which received two awards for its solid and innovative design.
description
The Hetzer construction is the main feature of the roof structure of a so-called Hetzer hall.
The Hetzer construction is a glued wood construction with so-called Hetzer binders or composite beams .
A Hetzer truss is a roof truss with an I- shaped cross-section. It consists of various types of wood glued together (beech for the pressure zone, spruce for the tension zone) and, depending on the span, can be provided with wooden or iron ties . A roof or hall structure built with it is suitable for the column-free vaulting of large rooms. The roof is polygonal in cross-section and can be covered with simple cardboard shingles. The walls can simply be plastered brick walls. Thanks to their relatively flat and column-free roof construction, the halls are built as assembly or storage halls, for example.
At the 1910 World Exhibition in Brussels , Otto Hetzer's self-supporting exhibition hall of the German railways (Hetzerbinder with iron drawstrings) with a span of 43 meters received two awards for its solid and innovative design.
Hetzerhallen in Weimar
The Hetzerhallen in Weimar , Thuringia, which is a prototype and is a listed building , was built in 1907 north of the railway line as a factory for Otto Hetzer Holzbau- und Holzpflege AG . Subsequently, the district Weimar-Nord was built later .

The “Kleine Hetzerhalle” built in 1907 survived on the site and is now (as of October 2019) used as a warehouse and beverage market. The hall has had a plaque of honor for Otto Hetzer since October 21, 2004.

- ^ Charles von Büren: Glued wood construction - a success story: 100 years of the Hetzer patent - On June 22, 1906, master carpenter Karl Friedrich Otto Hetzer received the German Imperial Patent No. 197773 for curved, glued laminated beams made of two or more lamellas. That was the hour of birth of modern timber engineering.
