Usage/Applications of steel structure/steel frame/steel construction

*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

 steel structure bridge

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 the reality, structure steel is widely used for high, large, heavy and light construction.

Q:Steel structure brush fire retardant coating per square meter kg?
Super thin steel structure fire retardant coating, grade two fireproof steel beam is generally between 1.2KG-1.5kg, steel column is between 1.5-2.0KG. The dosage per square point is only a theoretical amount. The amount depends on the design specifications, fire retardant coating, thickness and material loss at the workers' site. I hope I can help you
Q:What is a steel beam?
Homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; processing high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc.. Its disadvantage is poor fire resistance and corrosion resistance. Mainly used in heavy duty workshop bearing frame, dynamic power plant structure, plate and shell structure, high tower and mast structure, bridges and warehouses and other large-span structure, high-rise and super high-rise buildings.
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 to calculate the purlin of steel structure.
Single purlin weight =7.5* (0.16+ (0.06+0.02) *2-4*0.0025) *19.625=45.63 kg.You don't have 7.5 meters in the design bill, so you can ask about the design.
Q:What does "BH beam" mean in steel structure?
In steel structure, the reinforcement ratio of BH beam is B, which is the width of rectangular section; H (0) is the effective height of cross section.
Q:The position of the steel structure requires a spring cushion for mounting the bolt
High strength bolts (friction type) should be pre tension, and the spring washer is unfavorable to exert the pretension; the friction force produced by the high strength bolt in the preload moment is enough to prevent the looseness; therefore, no additional measures are needed to prevent loosening. Therefore, high strength bolts should not be equipped with spring washers.
Q:Steel structure, tied with brace pipe casing and how the difference? What difference?
The basic line tied in portal structure, drawing on the acronym XG, general specification for pipe 114, is connected to each portal frame brace; acronym T, general specification for the 12 round, the role is to the whole roof purlin
Q:How much is one square meter for steel structure paint?
So, the actual workload is actually derusting and corrosion protection: 45 yuan / square. That's the regular price.
Q:What does nonstandard steel structure mean?
There are non-standard and national standards, non-standard is a more special component, not conventional components,
Q:What are the meanings of I-beam BH300 x 200 x 6 x 8 on steel structures?
BH is welded to H type steel, not hot-rolled steel H from steel mill. Generally processed by the factory with three pieces of steel welded. BH300*200*6*8, i.e., high 300mm* wide 200mm* web 6mm* flange 8mm.
