François Hennebique

from Wikipedia, the free encyclopedia

François Hennebique (born April 25, 1842 in Neuville-Saint-Vaast ( Département Pas-de-Calais ), † March 20, 1921 in Paris ) was a French civil engineer and building contractor who was one of the pioneers in the use of iron and steel. Reinforced concrete was. His "System Hennebique" was licensed very successfully across Europe; the licensees in Germany were the construction companies of Max Pommer and Eduard Züblin .

biography

After an apprenticeship as a stonemason in Arras , he went into business for himself in 1867 and in the same year was in charge of the reconstruction of St. Martin in Coutrai . For two decades, until 1887, he worked mainly in Brussels , where he got to know the construction method with steel-reinforced concrete according to the Joseph Monier system .

In 1879 he himself used reinforced concrete for the first time to make an iron skeleton country house fire-proof by encasing the girders with concrete. In his examination of the new technology, he developed an economically very efficient construction of floor slabs as a monolithic system made of reinforced concrete.

In 1892 he opened an international engineering office in Paris and applied for the first patents for reinforced concrete construction based on the "Hennebique system". a. also for the T- beam , which is structurally important for the system , but which was declared invalid because similar solutions had already been found. Regardless of this, the office quickly became very successful and licensed the system to numerous construction companies. It also worked very often with contractors for construction work. In the following years, thousands of reinforced concrete structures were built according to the "Hennebique system".

“Maison Hennebique” in Bourg-la-Reine

From 1898, Hennebique published the programmatic newspaper “Le Béton armé”. Hennebique became known to a wide audience at the Paris World Exhibition of 1900 (Exposition Universelle et Internationale de Paris) for his innovative work in reinforced concrete construction .

Buildings

The countless and sometimes very different buildings by the office and its contractors can only rarely be clearly attributed to a particular designer. Well-known structures are:
