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:What are the protective coatings for steel structures? Do they need to be tested and sampled?
The main protective coatings for steel structure are protective primer, intermediate paint, finish coat and fireproof coating for steel structure. Mainly primer, fire retardant paintIn testing, primer, intermediate paint, finish coat and fireproof coating are required before entering. After construction, fire retardant coatings for steel structures need to be tested on-site (compulsory). Some protective paint also need on-site inspection (see supervision or design, etc.).Sampling should be representative and stir well. Take the amount of each test unit requires different paint class probably take 500-1000ml can. Fire retardant paint, if it is a thick powder, take at least 1500g. In general, we should take more, because the inspection unit to retain part of the original.Sampling and testing are witnessed and non - witnesses, it is best to notify the supervisor to the scene.
Q:What is the steel structure of portal frame and frame difference
Shelving structure: as the name suggests, a row of rows. Mainly used for single plant, by the roof and pillars and constitute the basis of horizontal plane, is the main bearing system of the plant, and then the plane frame is connected by the roof panel, crane beam, longitudinal support member, the overall space structure.
Q:Steel structure canopy belongs to the metal structure which component? Steel roof truss? Steel wall frame? Or steel grid?
The canopy is divided into two parts, one is the structure of part two is part of enclosure (that is, roofing materials, such as glass, aluminum plate, color plate etc.)
Q:What documents do steel installers need to have?
Steel erection workers need at least welder certificate, electrician certificate and hoisting certificate.
Q:Ask the two grouting steel structure column anchor bolts for what?
The steel column is the anchor bolt stress, because most of the construction of two pouring simply failed, not what role will the package effect, prevent the anchor bolts under the influence of environment corrosion. If the construction is qualified, should also participate in stress
Q:The difference between steel structures
In the subdivision, such as steel structural column: H steel column, lattice steel column, variable section steel column, box shaped steel column.Steel structure beam: H steel structure beam, lattice steel structure beam, variable section steel structure beam, box type steel structure beam, crane beam.
Q:The role of stiffeners in steel structures?
Under the condition of not increasing the wall thickness of the product, the strength and rigidity of the product are enhanced, thereby saving material consumption, reducing weight and reducing cost
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
Before welding, the welding materials, such as sundries and drug skins are thoroughly welded before welding, so as to guarantee the welding quality. Apply splash proof liquid around the weld and shall not weld, strike, test, or weld any part other than the weld.
Q:What is meant by a steel structure? What's the explanation for the trouble?
The term "limb" in a steel structure is most commonly used in latticed columns, in which the section, section, or plate is commonly referred to as the "limb". Like the limbs of a man, at the periphery.
Q:What is the main component in the steel structure and what is the secondary component?
But relatively speaking, such as columns on the ground fixed is the main component, if it is in the beam between the column is a member. The two ends of the beam are connected directly to the post, and the column is the main member, which is the main beam, and the minor beam between the beam and the beam is the secondary beam.
