METALS
A SMALL INTRODUCTION Humanity began to develop metallurgy, four thousand years ago, and 10. 8 centuries BC People are already treated with iron, smelted steel. Since metals have long been a reliable material for ship construction, transport, buildings and structures
Today it is impossible to construct any building without the use of metal. Major groups of metals and their alloys are two: black and colored. In the construction is mainly used ferrous metals.
COMMUNICATIONS Metals are used not only of construction of the building, but also in ensuring its communications. Among them, such as radiators, bathtubs, sinks, taps. Castiron pipes used for plumbing risers cabins, sewer systems, industrial water to drain. As well as conducting electricity, etc.
HIGH-RISE BUILDING Road building is currently the most promising technology for the construction of buildings. The technology of monolithic construction is a special formwork and reinforcement (structural elements made of concrete).
Iron concrete blocks of which is a monolithic building contains a large number of valves.
THE FITTINGS In monolithic construction metal is present as a reinforcement. It is divided into the rod fitting A 1, A 2, A-3, A-4. Steel reinforcing wire B-1, B-2
THE FOUNDATION The foundation is a very important element of the structure of the house, it is made of iron concrete, so the construction of any house you can not do without the metal.
Monument to the period of iron concrete construction in our country is the Ostankino Tower
ROLLING PROFILE In the construction of iron is used not only concrete but just iron. In this case, the most commonly used farm of rolling profile.
SKYSCRAPERS This technology has been widely developed in the U. S. in 20 years. And allowed to build tall buildings. But the first skyscraper built is considered to be in 1885 in Chicago Insurance Company Building
THE EIFFEL TOWER A unique monument of this technology is the Eiffel Tower is the most recognizable architectural landmark of Paris. March 31, 1889 Eiffel Tower was installed. Eiffel Tower was built in connection World's Fair to commemorate the centennial of the French Revolution (1789)
