Usage/Applications of steel structure/steel frame

*Characters of Structure Steel

1. Steel is characterized by high strength, light weight, good rigidity, strong deformation capacity, so it is suitable for construction of large-span, super high and super-heavy buildings particularly;

2. It with good homogeneous and isotropic, is an ideal elastomer which perfectly fits the application of general engineering;

3. The material has good ductility and toughness, so it can have large deformation and it can well withstand dynamic loads;

4. Steel structure’s construction period is short;

5. Steel structure has high degree of industrialization and can realize-specialized production with high level of mechanization.

*Steel structure application

1. Heavy industrial plants: relatively large span and column spacing; with a heavy duty crane or large-tonnage cranes; or plants with 2 to 3 layers cranes; as well as some high-temperature workshop should adopt steel crane beams, steel components, steel roof, steel columns, etc. up to the whole structure.

2. Large span structure: the greater the span of the structure, the more significant economic benefits will have by reducing the weight of the structure

3. Towering structures and high-rise buildings: the towering structure, including high-voltage transmission line towers, substation structure, radio and television emission towers and masts, etc. These structures are mainly exposed to the wind load. Besides of its light weight and easy installation, structure steel can bring upon with more economic returns by reducing the wind load through its high-strength and smaller member section.

4. Structure under dynamic loads: As steel with good dynamic performance and toughness, so it can be used directly to crane beam bearing a greater or larger span bridge crane

5. Removable and mobile structures: Structure Steel can also apply to movable Exhibition hall and prefabricated house etc by virtue of its light weight, bolt connection, easy installation and uninstallation. In case of construction machinery, it is a must to use structure steel so as to reduce the structural weight.

6. Containers and pipes: the high-pressure pipe and pipeline, gas tank and boiler are all made of steel for the sake of its high strength and leakproofness

7. Light steel structure: light steel structures and portal frame structure combined with single angle or thin-walled structural steel with the advantages of light weight, build fast and steel saving etc., in recent years has been widely used.

8. Other buildings: Transport Corridor, trestle and various pipeline support frame, as well as blast furnaces and boilers frameworks are usually made of steel structure.

All in all, according to thereality, structure steel is widely used for high, large, heavy and light construction.

Q:How is the steel structure foundation checked and accepted?
The column position in the column surface measuring axis of projectile.Level of plinth elevation. Concrete plinth elevation 50 ~ 60 mm for general casting (compared with steel column base design, installation in elevation) with steel plate or early adoption by plasma plate leveling.When using the steel plate support plate, steel plate area should be determined according to the fastening force and compressive strength, concrete of foundation base plate two times before grouting at the bottom of the column load and anchor bolt. The contact between the shim and the base and the bottom of the column should be smooth and tight.When the cushion plate is used, the shrinkage free mortar shall be adopted. The strength of the mortar block should be higher than that of the base concrete before the lifting of the column, and the mortar pad should have enough area to meet the requirements of the load.
Q:The exterior walls of steel buildings are colored steel plates, aren't they?
Color steel plate refers to color coated steel plate, color coated steel plate is a kind of organic coated steel plate. Color steel plate is divided into single plate, color steel composite board, floor plate and so on. Widely used in large public buildings, public buildings, movable rooms, and integrated housing walls and roofing.
Q:How long is the expected corrosion resistance of the general steel structure paint? Is there a relevant specification?
As ordinary steel structure anticorrosion coating, the composite coating iron red epoxy primer / epoxy micaceous iron oxide intermediate paint / chlorinated rubber finish form, life expectancy is 10 years.
Q:What are the accessories in the steel structure?
General steel structure project includes: steel column beam system, system, support system, connection system, system, and stair brace purlin. This is a part of every steel structure project. (single door, no stairs), you said the attachment should be the maintenance system.
Q:How can steel structures be made from bolts or bolts? High strength bolts are generally used for installation or production?
You must understand that a mounting bolt is used for installation, which is now in the welding joints of steel structure connection, the first fixed installation bolt and welding, the calculation only considers the weld resistance, the bolt itself does not force, with ordinary bolt.
Q:What is the difference between rigid connection and hinge in steel structure?. Are all high strength bolts connected just now?
The difference between the rigid connection and the hinge is whether the support passes the bending moment. Rigid transfer moment, hinge not transfer moment. Simply supported is hinged, solid support is rigid. High strength bolts are mainly used for shearing, and whether they are connected directly or not.
Q:What is the difference between a reinforced concrete structure and a steel concrete structure?
Steel structure with small weight, small stiffness, this time in the calculation of horizontal earthquake, earthquake will often than concrete structure, and its plasticity ability, at the time of the earthquake can absorb a large amount of energy, so the steel structure is better, but the steel structure is too soft, easy to produce a large horizontal displacement, and poor fireproof performance these are the concrete structure, than the poor areas
Q:Steel structure lateral inspection "z15" what does that mean?
In general, thick steel plate is easy to produce lamellar tearing, because the thicker the steel plate, the more non-metallic inclusion defects, and the thicker the weld, the greater the welding stress and deformation. To solve this problem, it is better to use Z to steel. This kind of steel plate is on the basis of a certain structural steel (called parent steel). After special treatment and processing, the content of sulfur is less than 1/5 of the general steel, and the shrinkage of the section is more than 15%. The mechanical properties of steel plates in the thickness direction (mainly ductility) are called Z properties. The Z properties of steel plates can be obtained by tensile tests of specimens, usually measured by cross-sectional shrinkage. China's production of Z steel plate to mark is in the parent class followed by Z to steel steel plate Z15, Z25, Z35 grade mark, the number after the Z word for section shrinkage index (%).
Q:Is the metal structure the same as the steel structure?
The metal structure is a general term, including the steel structure, aluminum alloy structure, etc.. Somewhere, the steel structure is confined to the structure made of steel. In the past, aluminum alloy structures were seldom used, and the metal structures were basically equal to steel structures. Now, the aluminum alloy structural design code has been promulgated and implemented, the aircraft also use titanium alloy structure, metal structure of the scope is more extensive.
Q:What can be painted on the surface of steel structure to prevent rust and corrosion?
Steel structure workshop: epoxy anticorrosive primer primer, intermediate paint epoxy micaceous iron oxide intermediate coating, fluorocarbon paint is above several matching scheme is one of the most common facilities, according to the different environment different anti-corrosion paint such as high-rise building steel structure, tower steel structure and so on, if not anticorrosive paint generally used in corrosion environment for epoxy zinc yellow / iron red primer, epoxy coal tar paint, such as in the harsh environment of the steel structure, generally used in the majority of zinc rich epoxy primer.
