The skate run is supported by goat racks, which, in addition, propagate longitudinal bars in certain places. Along the slopes at a distance of 70 cm, one from the other are located knots of iron strips attached to the rafters of brackets.
Extremely clean decoration of the details of the structure and the interfacing of all the elements of the rafters without a single bolt and rivets show the high skill of the Tula blacksmiths. After 85 years of existence, the rafters are in good condition. Quality makes itself felt. Also in the case of concrete floors. If you make concrete floors, then you can not worry about the resistance and reliability of such a basis.
In the first half of the XX in. In the development of iron structures, a new period began, qualitatively different from the previous. Inhaled rafters from bars and lanes of iron did not further develop, new structures arose.
The development of iron structures was due to the industrial revolution in England in 760-780., The then spread in Europe P Russia.
In 780 g. In St. Petersburg, a mechanical plant was founded to. N. Berda, which manufactured various equipment for industry and shipbuilding. But already in 805 g. In the textile industry of Russia, the use of steam engines and new weaving and spinning machines began. In Russian metallurgy, rolling mills acting from steam engines and blower machines in the production of cast iron appeared. The new equipment penetrated into metalworking, for which tools, machines and steam machines2 were imported into Russia from Europe2. In 83 g. In Russia, the construction of river iron steam ships began, and twenty years later, a rail cast iron road with a Cherepanovs steam locomotive was built at the Nizhny Tagil Plant.
The development of industrial transport and urban construction required new buildings and structures, and for their construction – a lot of cast iron and iron. However, Russian metallurgy, which occupied in XV in. first place in the world for smelting cast iron and iron, at the beginning of the XX in. began to fade into the background and gave way to England, where the production of cast iron rose sharply on the basis of the use of coke in the domain process.
