Product Description:

Steel Structure Building

1.the connection method of steel structure:

   welding connection or bolt connection

2.Steel structure design common norms are as follows:

  • "Steel Design Code" (GB50017-2003)

  • "Cold-formed steel structure technical specifications" (GB50018-2002)

  • "Construction Quality Acceptance of Steel" (GB50205-2001)

  • "Technical Specification for welded steel structure" (JGJ81-2002, J218-2002)

  • "Technical Specification for Steel Structures of Tall Buildings" (JGJ99-98)

3.The characteristics of steel

  • Light weight steel structure

  • Higher reliability of steel work

  • Steel anti-vibration (earthquake), impact and good

  • Steel structure for a higher degree of industrialization

  • Steel can be assembled quickly and accurately

  • Large steel interior space

  • Likely to cause sealing structure

  • Steel corrosive

  • Poor fire-resistant steel

  • Recyclable steel

  • Steel shorter duration

4.Commonly used steel grades and performance of steel

  • Carbon structural steel: Q195, Q215, Q235, Q255, Q275, Q345,etc.

  • High-strength low-alloy structural steel

  • Quality carbon structural steel and alloy structural steel

  • Special purpose steel

5.Market:

Products have been all over the country more than 20 provinces, municipalities and autonomous regions, and have been exported to Europe, North America, the Middle East, Africa, Asia and other countries and regions, the widespread use

Q:What does "PD140*4" and "PL12*150" mean in the steel structure drawing?
PD is a steel tube with a length of 140 and a diameter of 4.PL is a steel plate with a thickness of 12 and a width of 150.
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:In steel engineering, what is called rigid connection? What is articulated? What kind of nodes or structural parts are applicable to the two?
To connect by means of hinges. A device or part commonly used in two parts of a machine, vehicle, door, window, and implement, such as articulated trolley buses, articulated freight cars, articulated buses.
Q:What are the differences between steel structure design and reinforced concrete structure design?
When the ratio of the free length L1 of the compression flange to the width B1 of the cross section tubular support beam does not exceed the specified value.Structural measures shall be taken to prevent torsion at the end of the beam.For beams without lateral support points in the midspan, L1 is the span; for the beams with lateral supporting points in the midspan, L1 is the distance between the lateral supporting points of the compression flange (the lateral support of the beam is considered as lateral support).
Q:Steel structure brush fire retardant coating per square meter kg?
The amount of fire retardant paint is determined according to the coating thickness of fire-resistant coating, and the indoor thin steel structure fire retardant coating: the fire resistance limit of 2.5 hours per square meter is 6kg. Fire resistance limit of fire resistance limit of fire resistance limit of 2 hours per square meter was 4.5kg for 1.5 hours the amount per square meter 2.5kg 1 hours the amount per square meter 1.5kg indoor ultra-thin fireproof coating for steel structure: the fire resistance limit of fire resistance limit of fire resistance limit of 2 hours of consumption per square meter 3.5kg 1.5 hours per square meter per hour amount 2.9kg 1 the amount of 1.6kg square meters of indoor thick fire retardant coating for steel structure, fire resistance limit of 3 hours per square meter was 23kg. 2..0 hours of fire resistance per square meter dosage of 14kg
Q:Why are the main and main beam joints of steel structures articulated?
The hinged construction is convenient, the requirements of the secondary beam are large, the maximum bending moment is in the midspan, and the torsion resistance of the rigid beam is high.
Q:What is the performance and function of steel structure engineering?
Steel structure engineering is mainly made of steel, with large span, steel structure, workshop frame, steel structure workshop, light overall, saving foundation, little material, low cost and short construction period. Safe and reliable, beautiful appearance, stable structure and other advantages. Steel structure workshop is widely used in large span industrial buildings, warehouses, cold storage, high-rise buildings, office buildings, multi-storey parking lots and houses and other construction industry.
Q:Steel structure platform cost
The steel structure (General Plant) length: 100 meters wide, 30 meters high, 8 meters (total: 3000 square meters): steel frame (plant): 700 yuan / month (700 * 46=32200) steel: 200 yuan / square meter (200 x 3000=600000) wall: 90 yuan / square meter (90 x 3000=270000) total cost cost: 902200 yuan, 300 yuan / square meters of steel structure service life (25 years)
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:Which engineering structures are more economical and rational with steel structure?
In addition, because of its better force, the unit weight is much lighter than the concrete structure, and it is also suitable for high-rise buildings and super high-rise buildings
