Product Description:

Steel Structure Warehouse:

1.The steel structure of the connection method: welding 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 shorter duration
4.Commonly used steel grades and performance of steel Carbon
structural steel: Q195, Q215, Q235, Q255, Q275, etc.
High-strength low-alloy structural steel Quality carbon structural steel and alloy structural steel Special purpose steel Product Feature Carport, House, Office, Shop, Toilet, Villa, Warehouse, Workshop, Plant Other Information

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:Tall steel columns with studs what effect is there?
The fastener stiffness of stud belongs to a kind of connection of high strength, used in all kinds of steel structure engineering, in different joints in rigid composite connection. The stud is cheese head studs for arc stud welding (Cheese head studs for arc stud English welding) abbreviation, the studs specifications for the nominal diameter of 10 mm to 25mm, the total length of 40 ~ 300mm before welding.
Q:What is the difference between steel structure HN and HW?
HM is called mid flange H section steel. It is H steel with a flange width ratio of 1.33-1.75. It is mainly used as steel frame column in steel structure, and is used as frame beam in the frame structure which is subjected to load, such as equipment platform.
Q:What does "HJ-1" mean in steel structures?
In steel structure, HJ-1 is truss number 1.
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:How can steel structures be made from bolts or bolts? High strength bolts are generally used for installation or production?
It should be said that the steel structure is made unless a small number of bolts are used for positioning in the process equipment and the bolt is removed after completion of the assembly. All other bolts are mounting bolts, including high strength bolts. The production process does not use high-strength bolts, high strength bolt than ordinary bolt because of high cost and high strength bolt cannot be used for the two time in technology (because of the bolt torque coefficient needs to be determined, determination of the torque coefficient is discarded).
Q:In the steel structure safety margin refers to what?
The ratio of the structural stress to the design stress minus 1 is used as a positive fraction of the strength of the structure.
Q:Can the steel structure workshop be welded?
Construction: should be subject to the design of light steel structure of industrial buildings, the design is friction type high-strength bolt connection;Use period: prohibit welding on the structure.
Q:Installation quota, there are tubes, steel structures and general steel structure, how to distinguish between the two?
Installation is only water and electricity installation, that is, the general steel structure. I do not know what you said is the instructions, if it is the installation of water and electricity support, then the electrical and ventilation is a set of general steel structure (general iron component production, installation), the pipe is to use pipe stent installation.
Q:What is the difference between rigid connection and hinge in steel structure?. Are all high strength bolts connected just now?
If the steel column base section reduced, ribbed or not and anchor bar closer to the section is more biased hinge. Whether the beam has been joined or not, the simpler way is to see if the flange is welded. If welding is partial to the line, if it is not welded, it will hinge on the hinge.
