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:In steel engineering, what is called rigid connection? What is articulated? What kind of nodes or structural parts are applicable to the two?
Steel structure, beam to column connections are usually used in 3 forms, flexible connection (also known as articulated) and semi rigid connection and rigid connection. In engineering practice, how to distinguish a node belonging to the rigid and semi rigid or hinged connection depends on the rotational stiffness, rigid connection should not have obvious connection with the angle of angle deformation, reduce deformation of the structural resistance should not exceed 5%.
Q:What are the main structures and sub structures in the steel structure?
Main components: steel column, steel beam, crane beam and other large main componentsComponent: column bracing, horizontal support, tie bar, brace, casing etc.In addition to the purlin. I'm not sure whether it's the master or the second, and there's no definition.
Q:How can steel structures be divided into general steel structures, large steel structures and other steel structures?
For the general structure (such as general plant, Party A has no special requirements), tend to use more saving, anti rust effect is not very high iron red or red lead; but for the steel structure anticorrosive effect of higher requirements (such as bridge or country of some important buildings), have good anti rust effect of fluorocarbon paint, for example paint.
Q:How much is one ton of steel structure installed?
If the pipe truss, or grid, to 2000-3000 tons of installation costs, depending on the complexity of the structure and the amount of steel to be fixed.
Q:What is the price of the light steel structure?
We teach you a simple method: 1, steel structure processing fees (including primary and secondary structure of:1100) to 1300 yuan / ton (according to the component processing difficulty is also required to put the equipment, artificial, auxiliary structure, installation costs determine 2): primary and secondary component 400 ~ 500 yuan / ton, 3 maintenance structure installation fee (board): 10 yuan / square meters of the roof panel wall is 15 yuan / square meters; 4, pressure plate thickness for the different prices, different prices in 0.5 yuan, the thickness of 40 /m single board;
Q:Ratio of width to thickness in steel structure design,
The slenderness ratio of columns in the design of components in the main role is to calculate to consider the load bearing capacity of reinforced concrete columns under eccentric compression is long, due to the impact of additional eccentric component elastic-plastic deformation caused by the eccentricity, stability coefficient and coefficient of axial compression member, and the slenderness ratio.The columns are also divided into short columns, long columns and slender columns due to slenderness. From here we determine the type of column and, in practice, try to avoid slender columns
Q:What is the fire-resistant time of steel column under steel structure?
Steel is a building material that does not burn. It has the characteristics of shock resistance and bending resistance. In practical application, steel can increase the load capacity building relative, can also meet the needs of architectural design modeling, but also to avoid the defects of concrete building materials cannot bend, stretch, so the steel construction industry has been favored, monolayer, multilayer, skyscrapers, factories, warehouses, waiting rooms, lounges etc. the steel is very common. However, as a construction material, steel has some unavoidable defects in fireproofing, and its mechanical properties, such as yield point, tensile strength and elastic modulus, all decrease sharply due to the increase of temperature.
Q:What are the joint forms of steel structures?
Many, like the beam column node, beam and beam joint, diagonal node, combination node, the node you can look at the Atlas Design Institute issued, there is full.
Q:What CL6-3a stands for the steel structure of the roof purlin
The inner support component of the steel structure is made of high strength galvanized steel sheet, which is rolled into C and Z steel by precision machining.
Q:Why steel buildings have the best seismic performance?
1, under the same size, the steel structure has a lighter weight, and the seismic energy received in the earthquake is smaller;2, steel structure has very good ductility, each member of the moment deformation is easy to coordinate;
