Rebar<\/a> is widely used in building, bridge, road and other civil engineering construction. From highways, railways, Bridges, culverts, tunnels, flood control, DAMS and other public facilities, small to the foundation of housing construction, beams, columns, walls, plates, rebar steel are indispensable structural materials.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

With the deepening of urbanization in China, the booming development of infrastructure construction and real estate has a strong demand for Bewehrungsstahl\u00a0 steel. Reinforced concrete structure is still the main structural form of architecture in China at present and for a long time to come. Therefore, rebar demand and production can be expected to remain high.
According to statistics, the amount of steel used in China’s construction industry accounts for about 50% of total steel consumption. Construction industry is one of the industries with large resource consumption. To achieve sustainable development, it is necessary to adjust the consumption structure of building materials, vigorously apply high-strength steel bar and high-performance concrete, and take the road of energy-saving development. If the steel and concrete currently in use could be increased by one level of strength, there would be huge savings for society.
According to the calculation, if the main strength of reinforced concrete can be increased to 400-500N\/mm2 according to the requirements of the code, it can save about 10% of the current steel quantity.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

There are two commonly used classification methods of rebar:<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

First, according to the geometric shape, the cross-section shape of the transverse rib and the spacing of the rib are classified or classified, such as the British standard (BS4449) will be divided into \u2170 type, \u2171 type Bewehrungsstahl. This classification mainly reflects the grip performance of Bewehrungsstahl.<\/p>

The second is the performance classification (level), such as China’s standard (GB1499) according to the strength level (yield point\/tensile strength) rebar is divided into 3 grades; Japanese industrial standard (JISG3112) according to the comprehensive performance of rebar is divided into 5 types; The British standard (BS4461) also specifies a number of classes of rebar performance tests.<\/p>

According to statistics, the amount of steel used in China’s construction industry accounts for about 50% of total steel consumption. Construction industry is one of the industries with large resource consumption. To achieve sustainable development, it is necessary to adjust the consumption structure of building materials, vigorously apply high-strength steel bar and high-performance concrete, and take the road of energy-saving development. If the steel and concrete currently used were to be strengthened by a single grade, huge savings could be made to society.<\/p>

For example, according to the requirements of the specification, if the strength of the dominant force of reinforced concrete is increased to 400-500N\/mm2, it can save about 10% of the current steel level.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Rebar belongs to small section steel, mainly used for the skeleton of reinforced concrete building components.Bewehrungsstahl is usually used in reinforced concrete, the role of its stripes is to increase the friction force, so that Bewehrungsstahl and concrete occlude together, forming a body, under the action of external force will not produce the phenomenon of twitch, improve the strength of concrete.<\/p>

The difference between Bewehrungsstahl and round steel bar is that the surface has longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs evenly distributed along the length direction.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The finished quality of threaded steel bar varies with smelting furnace and hot rolling batch. Batch number and batch number are the basis of sampling inspection. Therefore, import and consumption departments and storage departments should pay attention to retain the marks on the goods, export enterprises and foreign trade departments should distinguish batches, furnace numbers and provide quality certificates according to the standard requirements.
Rebar is generally naked lashed delivery, storage should pay attention to moistureproof, corrosion on the performance of rebar will have adverse effects.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
