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 is the two steel structure?
Steel structure decoration member used in outer eaves decorationFor example, steel structure canopy, steel structure, glass curtain wall etc.
Q:The exterior walls of steel buildings are colored steel plates, aren't they?
The exterior wall is mounted with coloured steel plates.
Q:What does the steel structure lug 2-240*290*12 mean?
Steel structure connecting lug 2-240*290*12 means 2 pieces, steel plate of thickness 12MM, length 290MM, width 240MM.Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:Ratio of width to thickness in steel structure design,
Slenderness ratio refers to the bar length and the member sections turning radius ratio, note that is calculated length bar, and calculate the length of rod end of the connection, such as fixed, hinged, links, freedom, slenderness ratio is not long and short side ratio. The turning radius is a material mechanics concept, the complexity of the computation.Slenderness ratio refers to the bar length and the member sections turning radius ratio, note that is calculated length bar, and calculate the length of rod end of the connection, such as fixed, hinged, links, freedom, slenderness ratio is not long and short side ratio.
Q:What documents do steel installers need to have?
Steel structure installation work requirements: structure; material, surface roughness, tolerances, surface treatment, straightness (or arc) connection; hole deviation, bolt grade; welding method, welding standard, welding materials; tightness requirements
Q:What are the joint forms of steel structures?
The steel structure joints are divided into rigid joint and hinged joint, and the joints in the truss are many, because the steel pipe is used more.
Q:What does the horizontal support of steel structure mean?
Horizontal support generally means that the support system is parallel to the ground and opposite to the vertical support. A vertical support means that the plane formed by the system is perpendicular to the ground or perpendicular to the plane in which the roof is located.
Q:What does steel structure "Zhongshan wall post" mean?
The utility model is provided with a reinforced concrete structural column resisting the horizontal wind load in the gable of both ends of the brick concrete structure, and is simply called a wind resistant column. A reinforced concrete beam that connects the wind column in the horizontal direction and acts as an integral reinforcement is referred to as a wind resisting beam. Generally used for high-rise, large internal space, less walls of brick concrete structure housing, such as industrial plants, large warehouses and so on.
Q:What is the difference between steel structure, light steel workshop, color steel room and movable room?
The frame of light steel structure buildings are H steel, I-beam, door type steel frame and Rachel purline, retaining structure is also useful for color plate and masonry wall. Multi-purpose in large companies, factories, warehouses, exhibition halls, integrated stadiums, shopping malls and so on.
Q:How long is the fire resistance rating of steel structure two?
Fireproof steel can be used (or concrete masonry brick, fireproof coating method), fireproof coating and composite structure of several methods of fire prevention board can be divided into fire plate and sheet thickness, the thickness of fireproof plate thickness is 20 ~ 50MM, the main fire board of calcium silicate and stone fire expansion borers in main varieties KB board, CF board; fireproof sheet thickness between 6 ~ 15MM, the main varieties of inorganic plate reinforced short fiber reinforced cement pressure plate, the ordinary fiber reinforced calcium silicate plate and glass cloth.
