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

Q:Does the steel structure belong to high-risk industries?
In accordance with the procedures prescribed by the state: first entrust qualified units to prepare the feasibility study report, preliminary design to find a qualified department for construction project, after the application of safety pre evaluation certificates a book, and the Safety Supervision Bureau issued approval certificate, after the completion of the construction for the safety evaluation report for safety production license.
Q:What are the main steel structures in the steel structure and which are the secondary steel structures?
You've split the question for me! Why don't you know?!! The main structure is the component that carries the main load. The same as the frame structure construction, (beam, column and slab is the main component), steel structure without transfer plate force, then only the beam column is the main component, such as roof frame, purlin, beam, sub beam, column. Then the members without any force are secondary members, such as steel drains, windproof rails, and ladders.
Q:What is steel structure steel plate?
Steel structure column spacing of 5~9.0m * 8~15m, secondary beam spacing of 3M, and the floor plate length is 4.97~8.97m, the transportation and installation is difficult, especially with the arc area of vertical lifting floor plate, from top to bottom in the secondary beam is sheathed HAZAMA is difficult, and disturb the normal beam welding process.
Q:What is the difference between rigid connection or hinge in steel structure?. Are all high strength bolts connected just now?
Is to see the node connecting column or beam can rotate around the node, not rotating, that is articulated, can not rotate, that is, consolidation. The simply supported joint is the hinged support, and the rigid joint is the rigid joint of the joint. High strength bolts are not rigid, in the beam web connection, is articulated, ideal for Web Center is a bolt, you can think about it if the middle of the beam stress, beam can rotate around the bolt, but the flange has high strength bolts or welding flange. Do you want to look at the beam can rotate around the node? You understand that, and it's easy to understand when all the bonding is done.
Q:What plate is the slab below the concrete floor of the steel structure?
In order to meet the requirement of rapid construction of the main steel structure, a firm platform can be provided in a short period of time, and a plurality of floors can be used for laying profiled steel plates, and the concrete flow of the concrete slab is divided into layers.
Q:Who knows what HW, HN and HM mean in steel structures?
It should be the difference between the elements added to different steels.HW is high tungsten, HN is high nickel, HM is high manganese
Q:What does nonstandard steel structure mean?
As far as I can see, it does not conform to the building modulus, which is not in the standard atlas.
Q:The difference between steel structures
In the subdivision, such as steel structural column: H steel column, lattice steel column, variable section steel column, box shaped steel column.Steel structure beam: H steel structure beam, lattice steel structure beam, variable section steel structure beam, box type steel structure beam, crane beam.
Q:What is the difference between steel structure, light steel workshop, color steel room and movable room?
The main difference between the company's light steel structure and the color steel plate movable room is that the materials used by the two are different, and the prices are different. Choi steel movable room is relatively simple, safe and practical. Light steel structure seismic, light weight, environmental protection, construction cycle fast.
Q:How long is the fire resistance rating of steel structure two?
Therefore, when the fire resistance rating of steel structure is two, the refractory time requirement of the component is as follows: column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. The steel structure can be made up of wrapped concrete (or masonry bricks), fireproof coating, fireproof board cladding and composite structure, and the required refractory time can be achieved.
