Light Medium Heavy Structural Steel Fabricating Plant Powder Building Box Column

Product Specification

Multi Storey Heavy Steel Structural Powder Plant Building Box Column Frameworks

The steel structure has the advantages of high bearing capacity, small cross-sectional size, and light overall weight of the building, and is most suitable for the construction of high-rise buildings. Compared with reinforced concrete structures, it has greater toughness, ductility, deformation capacity and energy dissipation capacity, and is the preferred structure type for high-rise buildings in earthquake areas. Steel-concrete hybrid structure is a new type of high-rise building structure developed recently. It combines the advantages of both steel structure and reinforced concrete structure, and has achieved good economic results.

Specification:

The use of steel structures in tall buildings has the following advantages over the use of concrete structures:
(1) Steel structural material has high strength and light weight
The steel structure has high strength. Compared with the concrete structure, the steel structure beam and the column cross-sectional area are small, which can increase the effective use area. Generally, the cross-sectional area of ​​the high-rise steel structure column accounts for about 3% of the building area, and the cross-sectional area of ​​the high-rise concrete structure accounts for 7%-9% of the building area.
(2) Steel structure construction speed is fast
Most of the steel structure is produced in the factory and transported to the site for integral assembly by welding or bolting. It can be used all day, because the steel structure itself can be used as a load-bearing structure for the construction load to reduce the formwork during construction, thus not only reducing costs, but also greatly speeding up Construction speed. The construction speed of the steel structure is about 1.5 times that of the concrete structure.
(3) Convenient pipeline layout
In the structural space of the steel structure, the truss type member or the member having the cavity can be used, so that the arrangement of the pipeline is convenient, and the replacement and repair of the pipeline is convenient. However, if a concrete structure is used, the beam should not be opened, and the pipe generally passes under the beam, thereby occupying a certain space. In the case of the same floor height, the floor height of the steel structure can be smaller than the floor height of the concrete structure, which can reduce the area of ​​the outer wall.
(4) The steel construction environment is less polluted
When steel structure is constructed, sand, stone, soil, cement and other materials are rarely used, and pollution problems such as dust flying, waste accumulation and noise are avoided from the root wood.
(5) Steel structure construction conforms to sustainable development policy
The steel structure industry is a green-bag environmental protection construction industry. It is relatively reasonable in the use of resources and energy, and has relatively little damage to the environment. It is a breakthrough in solving environmental problems. Steel is a material with a high recycling value and scrap can be recycled. For buildings of the same size, the emission of harmful gases during the construction of the steel structure is only 65% ​​of that of the concrete structure.

Application:
As an important load-bearing structural system, steel frame structure is widely used in residential, office, entertainment and other public buildings.
