Fire resistance, strength, high rigidity and lower cost of monolithic reinforced concrete floors in comparison with ceilings on metal beams – these factors often turned out to be decisive when choosing the structures of ceilings and coatings, beam bridges for highways and railways.
In the 90s, Genebik founded his company with 44 branches in different countries, including in Russia. Gennesybik received the successful use of the system in the south of Russia – in Yekaterinoslavl, Kerch, Nikolaev, Novorossiysk, as well as in Moscow. By 900 g. The total area of ceilings built according to the Gennesbik system was 30,000 m2 in Russia.
The first beam bridge according to the Gennembik system was built in Russia in 1905. a total length of about 9 m.
Many of the authors of systems that first received patents in Western Europe and the USA acquired Russian privileges. We list only a few of them who have received practical application in Russia.
In 1897 and 1902. The privilege on the structure of a ribbed slab made of reinforced concrete for ceilings and bridges has received m. Krenen. In 1898. Hungarian. I took a privilege on the device of strong floors from iron wires and concrete. January 24, 1890. a privilege was issued to the Hungarian engineer and. on the design of coatings from reinforced concrete beams with consoles in the upper part, August 1902. Englishman in. F. Goldin has acquired a privilege for metal for reinforced concrete partitions and plates. In 1908. Austrian privilege was issued to the lattice reinforced concrete beams – farms with allel belts. This system has become widespread in Russia. For it, in particular, a construction company in. Jacobi in 1909. A bridge with a maximum span in the middle of 8.5 m was built in Kaluga.
In Europe, bridges were built from the beams with a span of 5-22 m. Before the First World War, a small factory worked near Moscow, which made Vizitini’s beams for civil and industrial construction.
In 1892. privilege No. 2202 was issued to the Austrian engineer on the design of hollow reinforced concrete columns with an internal core of metal pipes and a spiral winding outside. These columns were used for large loads.
Of course, each building needs high -quality windows. To date, the windows of the century are the leader in the production of windows. You can purchase plastic windows of the eyelid from a visionary in St. Petersburg at excellent prices.
