As early as 1992, Leander Bathon had the idea of embedding hollow cambered steel parts into wood in order to bind wood together with other building materials. In 2000, Bathon introduced the innovative wood-concrete composite system with glued-in steel parts to the international audience at the “World Conference of Timber Engineering” in Canada. Timber construction engineer Rainer Bahmer, who was at the time the CEO of a timber glue construction company, recognized the potential of glued connectors for timber construction.
The first test pieces were then manufactured in cooperation with RheinMain University (formerly known as Hochschule Wiesbaden). The positive results of preliminary trials with smaller test pieces with beams and a 10 m 1:1 test piece as a plate, plus a few smaller construction objects relating to the renovation of old buildings, led to the development of the “HBV system”. In 2000–2001, the first HBV floor with glued-in HBV shear connectors was installed in an office building with a span of 10 m and an area of 400 sq. m. Various steel plates and adhesives for the wood-concrete composite were also tested at the same time in numerous further trials between 2000 and 2002.
Initiated by Prof. Bathon, the Labor für Holzbau (timber construction laboratory) was set up in September 2002 as an institution of the Architecture and Civil Engineering faculty at RheinMain University, known today as one of the leading research institutions for timber construction. General building authority approval issued by the German Institute for Construction Technology (DIBt) in Berlin has been in place for the HBV system since March 2004, under number Z-9.1-557. Numerous load-bearing structures have been installed with the HBV system since 2004, with a total area now covering more than 100,000 sq. m. Rainer Bahmer then founded TiComTec GmbH in 2006. The aim of the company is the further development and sale of the HBV and HSK systems. As a research institution, the Labor für Holzbau focused on further composite structures in the years that followed.
The aim was to find a wood-steel composite adhesive solution and this was achieved through the development of glued-in perforated metal plates. It took around 10 years to develop these, with the reward being the Schweighofer Innovation Award in 2013. Known today as HSK systems, general building authority approval was issued for these products in November 2014 under number Z-9.1-770.
