Joseph-Louis Lambot (born May 22, 1814 in Montfort-sur-Argens , † August 2, 1887 in Brignoles ) was a French inventor. He is considered to be one of the inventors of reinforced concrete, from which reinforced concrete developed.

family

Lambot studied in Paris. In 1841 he returned to the Miraval family estate near Correns in southern France, where he ran agriculture.

The invention

There he also began to try to make barrels, flower vases and other small items of equipment out of concrete with built-in reinforcements of wire mesh . In 1849 or 1850 he built a concrete boat in the same way . He patented it for France on January 15, 1855, and shortly afterwards also for Belgium, and exhibited it at the 1855 World's Fair in Paris. However, the invention received little attention and the inventor was soon forgotten.

Impact history

In Italy, Carlo Gabelini began to build concrete boats with some success from 1896 onwards. In 1909 in Frankfurt am Main , the engineer B. Nast designed a 42 meter long and 6.3 meter wide transport barge with a capacity of 200 tons, which was built by the Verbundbaugesellschaft mbH . Three transverse walls divided the cargo space into four compartments and "the fore ship is set up as a living room, the approximately 5 m long cabin above it is also made of reinforced concrete". It was used to transport gravel and concrete on the Rhine and Main . In the USA , concrete ships with a deadweight of 5,000 tons are said to have been built . In other countries, too, there have been a number of experiments with ships made of reinforced concrete. The concrete ships built in France during the First World War due to a lack of steel made use of the technology developed by François Hennebique and did not fall back on Lambot's invention.

Of the - at least two - original boats that Joseph-Louis Lambot built, at least one was still swimming on the lake in the Miraval Park in 1902 . Two such boats were salvaged there in the 1950s. One is on display in the Museum of Brignoles , while a second was in the collection of the Musée des arts et métiers and has now disappeared.
