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?
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 main steel structures in the steel structure and which are the secondary steel structures?
Frames, beams, columns and supports constitute the main structure of the structure, and generally include stairs, platforms and so on
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
All welds shall be full weld, and the weld height shall be in accordance with the drawing design requirements, and the minimum weld angle shall not be lower than the thickness of the sheet to which it is attached. Pay special attention to the welding height at the bottom flange and bracket. Butt welded flange plate to mouth, gouging completely after welding, arc welding lead must be added before the weld shall not be lower than the parent material, and more than high not greater than 2mm, more than high or welding to grinding clearance with grinder. After welding arc plate will lead plane, with grinder will edge polishing.
Q:How to calculate the steel structure quota?
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is made up of steel beams, steel columns and steel trusses made of shape steel and steel plate.
Q:What is the brittle fracture of steel or steel structure?
Tensile strength or yield strength of steel in tensile tests
Q:Steel structure, tied with brace pipe casing and how the difference? What difference?
The casing is pipe, casing is roof straight brace at the oblique brace increase casing
Q:Does the column of steel structure do the ground beam or do it directly?
The embedded bolt shall be accurately laid on the foundation according to the location and size. When the foundation is deep, the foundation top extends a thick short column, the pre buried bolt in short columns, pay special attention to ensure accurate position and size of bolts.
Q:What is the budget for steel structure?
Pre buried bolt, steel columns, steel truss, steel beam, steel support, wall, roof purlin purlin, etc.,Each project calculates the area of the corresponding parts, then multiplies the theoretical weight, and then divides the amount by 1000 into a ton,For example, the wind column in this figure is H350*200*6*8, length of 9 meters, it means that the wind column is a H steel, the middle is 6mm thick, width of 350mm steel plate, both sides are 8mm thick, width of 200mm steel plate,
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:How much is one square meter for steel structure paint?
Different paint, brush mode, operation height have an impact on the cost, the specific circumstances of the specific treatment.
