Слайд 2a 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

a small introductionHumanity began to develop metallurgy, four thousand years ago, and 10.8 centuries BC People are

Слайд 3Today 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.

Today it is impossible to construct any building without the use of metal. Major groups of metals

Слайд 4communications
Metals are used not only of construction of the building,

but also in ensuring its communications. Among them, such as

radiators, bathtubs, sinks, taps. Cast-iron pipes used for plumbing risers cabins, sewer systems, industrial water to drain. As well as conducting electricity, etc.

communicationsMetals are used not only of construction of the building, but also in ensuring its communications. Among

Слайд 5High-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).

High-rise buildingRoad building is currently the most promising technology for the construction of buildings. The technology of

Слайд 6Iron concrete blocks of which is a monolithic building contains

a large number of valves.

Слайд 7The 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 fittingsIn monolithic construction metal is present as a reinforcement. It is divided into the rod fitting

Слайд 8The 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.

The foundationThe foundation is a very important element of the structure of the house, it is made

Слайд 9Monument to the period of iron concrete construction in our

country is the Ostankino Tower

Слайд 10rolling 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.

Слайд 11Skyscrapers
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
