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.

Q:Steel structure brush fire retardant coating per square meter kg?
1., thin steel structure fire retardant coating 1.2kg/mm, and then multiplied by the construction of fire retardant coating thickness can be.2. ultra thin steel structure fire retardant coating 1.6kg/mm, then multiplied by the construction thickness of fire retardant coating can be.3. thick steel structure fire retardant coating 1.0kg/mm, then multiplied by the construction thickness of fire retardant coating can be.In the same project, the coating thickness of different refractory grades is different, and the thickness is determined according to the inspection report of fireproof coating factory.When you choose to buy, it is necessary to determine the fire limit of your construction, attention to choose fire-resistant steel structure fire-resistant coating.
Q:What does LL represent in steel structures?
Generally, coupling beams have small span, large section and large stiffness of wall connected with coupling beams. Generally, the internal forces of the coupling beams are often large under the influence of wind and earthquake loads. In the calculation of internal force, the stiffness of the coupling beam is usually reduced, but the displacement calculation is usually not reduced.
Q:How is the steel structure foundation checked and accepted?
The column position in the column surface measuring axis of projectile.Level of plinth elevation. Concrete plinth elevation 50 ~ 60 mm for general casting (compared with steel column base design, installation in elevation) with steel plate or early adoption by plasma plate leveling.When using the steel plate support plate, steel plate area should be determined according to the fastening force and compressive strength, concrete of foundation base plate two times before grouting at the bottom of the column load and anchor bolt. The contact between the shim and the base and the bottom of the column should be smooth and tight.When the cushion plate is used, the shrinkage free mortar shall be adopted. The strength of the mortar block should be higher than that of the base concrete before the lifting of the column, and the mortar pad should have enough area to meet the requirements of the load.
Q:The exterior walls of steel buildings are colored steel plates, aren't they?
The exterior wall is mounted with coloured steel plates.
Q:Why can't epoxy paint be used in outdoor steel structures?
Epoxy paint used as primer, iron red epoxy primer, epoxy zinc primer can be matched with acrylic polyurethane paint, fluorocarbon paint, etc. for outdoor weatherproof coating.
Q:What is a steel structure?
The steel structure is made of steel beams, steel columns, steel trusses and so on. Each component or component is usually welded, bolted or riveted.
Q:What does "fixation" mean in steel structures?
The solid connection is the rigid connection, which completely limits the relative displacement and the rotation angle of the two members at that point. The rigid joint can transfer the axial force, the lateral force and the bending moment to each other.
Q:What is the difference between a reinforced concrete structure and a steel concrete structure?
Steel frame structure is mainly made of steel, and it is one of the main types of building structures. The utility model has the advantages of light weight, high reliability of work, good vibration resistance and shock resistance, high industrialization degree, easy sealing structure, easy corrosion and poor fire resistance, etc..
Q:Is the metal structure the same as the steel structure?
Dissimilarity。 Steel structures can only be attributed to one of the metal structures. There are other building materials, such as aluminum alloys commonly used in curtain walls, aluminum or magnesium alloys for large roofs, or copper panels.
Q:The steel structure not brush rust which is based on the specification
GB 50205 there should be a description of surface paint base and high strength bolt connection. Should be only domestic standards, I think many foreign projects have done paint
