Trautsch-Pieper method
The Trautsch-Pieper process is a process with the help of which roof trusses can be built with slag hollow blocks. It replaces the usual wooden roof structures. The process was initially used in church and industrial buildings.
history
The Trautsch-Pieper process was developed by the builder and contractor Erich Trautsch and the civil engineer Klaus Pieper in 1956. Erich Trautsch initially had this idea. After the war , he began to think about how to rationalize materials in construction. During the war, Erich Trautsch had received the order to build the first section of the (now defunct) power plant in Lübeck-Siems . As he thought about it, he noticed that the power plant was producing enormous amounts of slag as a by-product. His idea was to make a special stone shape from this slag. It succeeded, and in 1951 he received approval for the so-called “Trautsch stone” from the German Standards Committee.
At the same time, he made attempts to develop roof structures from specially shaped hollow cinder blocks. In order to obtain approval for the so-called “Trautsch roof”, he went to Klaus Pieper. At that time he was the building officer and head of the municipal building department for statics in Lübeck. Erich Trautsch had developed a prototype of this "Trautsch roof" for stone production on his premises , which was 8 meters long and 8.5 meters wide. Klaus Pieper inspected this roof and was enthusiastic because there was hardly any wood in Germany at the time of the reconstruction. Pieper did all the static calculations for this roof construction. The different stress tests were carried out. In March 1952, Erich Trautsch applied for a patent for the “Trautsch roof”, and on January 25, 1953 he received it from the German Standards Committee.
The “Trautsch roof” was also well suited for residential buildings, but not for larger construction projects. In the spring of 1955 Pieper approached Trautsch and made the proposal to modify the "Trautsch roof". The aim was to widen the range. The “Trautsch Stone” was 125 cm long, 25 cm high and 32.5 cm wide. Pieper's idea was to insert a reinforced concrete rib with steel inserts 10 cm wide between each “Trautsch stone” . As a result, more rigidity and load-bearing capacity could be achieved with a much wider range. Erich Trautsch built the first prototype within two months. Pieper did the static calculations as before and on April 16, 1956, both received the patent. The procedure was used for the construction of more than 5,000 apartments as test and comparison buildings and for another 5,000 apartments in a slightly modified construction with lava stones.
meaning
Since the Second World War , over 400 church roofs and steeples have been built in Germany using the “Trautsch-Pieper process”. These include the rebuilt churches in downtown Lübeck: Petrikirche , Dom and Marienkirche .
