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 steel structure of portal frame and frame difference
The bent frame is the two row of columns, the roof trusses above, and a board placed between the roof trusses of the two rows of columns, forming a continuous structure.
Q:What is the roof of a steel structure?
Generally applicable to concrete roof structure, general standards of drainage, the minimum slope is five of the span of the house, that is to say, if the total width of the house is 100 meters, the slope should be no less than 0.5 meters! Special emphasis is also placed on: if the roof is tiled, the standard is greater than or equal to 10 degrees, and less than 75 degrees. Depending on the structure of the house, geographical location, tile roofing material determines the final slope size!
Q:Large steel structure stress analysis, what software is good?
Landlord said SW, COSMOS, 3D3S, I have not used, do not comment. As for the PKPM software is the mainstream architectural design software, the rules of the structure is more applicable. The concept of a major feature of this software is "layer" is more obvious, is relatively rigid, through the "layer" bar calculation results often appear abnormal (such as crossing the floor column and brace etc.), so the industrial equipment no floor concept, to be especially careful when using. The panel you said could not be analyzed by finite element method.But PKPM also has the advantage, that is, get started quickly, for architectural design is relatively user-friendly, you just follow the prescribed steps step by step, you can basically complete modeling. In addition, he close to domestic norms, post-processing easier.Of course, some of the PKPM modules, I did not fully use, the evaluation of PKPM may not be accurate, comprehensive, please correct me downstairs.
Q:I want to make light steel structure. What tools do I need?
Another major content of the construction of steel structure is welding. The field welding equipment is mainly manual welding. As the labor costs are increasing day by day, in order to improve the efficiency, the gas shielded welding is becoming more and more popular at the installation site. Welding auxiliary equipment is the drying equipment of welding rod: drying machine.
Q:Who knows what HW, HN and HM mean in steel structures?
TM, TN, TW also refers to the middle flange, narrow flange, wide flange, T steel, in which the width of the wing refers to the flange width, B= section height H, mid wing refers to B= (1/2~2/3) H, narrow wing refers to B=1/3~1/2H
Q:What does steel structure HW stand for?
H is divided into hot-rolled H steel and welded H steel (H) two, hot-rolled H steel is divided into wide flange, H steel (HW), flange H (HM) and narrow flange H (HN) three.
Q:Steel structure workshop and equipment have static electricity is how?
Remind: if you hit the steel structure was not necessarily static, static steel structure, but you have the electrostatic savings, met steel structure rapidly after being led into the earth, you have been playing the static feeling, this is the most general.
Q:Housing cost of civil steel structure
If you stay. The structure can be made of steel structure, but the wall must be made of brick, cement and other exterior wall insulation materials.Steel structural frames must be of type H steel. As far as the price is concerned. Hard to say. All have to budget according to specifications and drawings. But I think it's better to be an ordinary house. There's no need for that mess.
Q:What is the material in the steel structure?
This material refers to the composition of steel structure required steel, plates can also be said to be reinforced beams, screws, flanges, stiffeners, and so on.
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
The building of the steel beam, steel column, ladder and other metal components and metal curtain wall column should be taken as the lead line, but between the various parts shall be connected through electrical, the copper zinc alloy welding, welding, crimping crimping, sewing, screw or bolt connection; the cross section should be according to the specification in table 5.2.1 the specified value; each metal component can be coated with an insulating material.
