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:How can steel structures be divided into general steel structures, large steel structures and other steel structures?
There is no standard and strict definition of steel structure division.
Q:Steel structure canopy belongs to the metal structure which component? Steel roof truss? Steel wall frame? Or steel grid?
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure
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:In the steel structure of steel purlin 160*60*20*2.5 is what mean
Stands for 160mm height, 60mm width, and 2.5mm thickness, and 20mm is the size of two small ears
Q:Why should we add air holes to the embedded parts of the steel structure?
The embedded piece is too big, and the air vent is also called an overflow hole, and the vibrator can be inserted into the vibrating concrete from the hole, and the concrete under the embedded part is more compact and clings to the embedded part
Q:Why steel structure does not fire?
From the relationship between mechanical properties and temperature of steel, it can be concluded that the general trend is that the strength of steel decreases and the deformation increases with the increase of temperature. At 200 degrees or less, the performance of steel is not changed greatly; between 430 and 540 DEG C to strength decrease sharply; very low intensity can not bear the load of 600 DEG C, in addition to a blue brittleness phenomenon in the near 250 DEG C, about 260 to 320 DEG C when the creep phenomenon.
Q:What does steel structure HW stand for?
HM is a H steel, whose height and flange width ratio is roughly 1.33~~1.75. It is mainly used as steel frame column in steel structure, and used as frame beam in frame structure subjected to dynamic load
Q:What is the fire-resistant time of steel column under steel structure?
In order to make the steel structure materials overcome the shortage of fire protection in practical application, fire prevention must be carried out, the purpose of which is to raise the fire resistance limit of the steel structure to the limit range prescribed by the design specification. To prevent the deformation of steel structure in heating in the fire quickly, the measure is varied, the key is to adopt different methods according to different situations, such as the use of thermal insulation and refractory material directly blocking flame burning steel structure, reduce the heat transfer rate of temperature rise, steel structure to postpone the weakening time. But whatever the method, the principle is the same. Here are some different steel structure fire protection measures.
Q:Where is the steel structure? High strength bolts?
Steel structure is generally beam column connection, beam and beam connection with high-strength bolts, if the high-rise steel structure building support system should also use high strength bolts
Q:What is an engineering structure?
The main vertical frame structure stress system composed by Liang Hezhu; the main vertical shear wall structure of the mechanical system composed of reinforced concrete wall; tube structure is in the high-rise building, the elevator wells, tube wells such as stairways or enclosed walls formed within the tube, can also be used in exterior or close packed column as the outer tube, or both the formation of tube in tube structure, frame, shear wall and tube can also be combined to form a frame shear wall structure and frame tube structure system; tower structure is fixed at the lower end, top free towering structures; the mast structure is composed of a bottom hinged or rigid structures erect slender pole mast and a plurality of layers of cable composed; bearing structure is composed of a flexible cable structure by cable and edge components, cable material can be used in steel beam, steel wire, steel strand Wire, bar, fiber composite materials and other good properties of wire tension; and the floor load through a sling or transfer to the level of suspension boom is fixed on the barrel body or pillar beam or truss, and through the cylinder or post transmission to the structure known as the foundation of the system of suspension structure; shell structure is composed of a curved plate with the edge member (beam, arch and truss) space structure; truss structure is a plurality of bars in a certain grid form spatial structure through the connection and the formation of;
