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.

Q:Why steel structure does not fire?
When the temperature is about 250 degrees Celsius, the tensile strength increases locally, the yield strength rises, the strength increases, and the plasticity decreases, and the material turns brittle.Creep is the phenomenon of steel deformation at a very slow speed in the range of 260 DEG C to 320 DEG C under the condition that the stress remains constant. With the performance of 200 DEG C has no change in the material properties, the surface structure of the radiation temperature should not exceed 200 degrees, the current steel structure industry regulation of the temperature to 150 degrees is appropriate, beyond which the temperature should adopt fire insulation protection.
Q:Why steel structures are more suitable for building tall and high-rise buildings?
In fact, more reasonable, in the future development trend driven by the mixed structure of economic rationality, and good technical performance so that it can occupy a place,
Q:What is a steel beam?
The structural beam, as its name suggests, is a structural beam made of steel.
Q:Ask the two grouting steel structure column anchor bolts for what?
But mainly by the anchor bolts to stress. The steel column base connection is hinged and rigid, rigid two pouring pouring depth 100mm, pouring depth two time pouring hinged 50mm in steel structure regulation on the stress problem. Of course I saw just according to make a person views.
Q:What is the performance and function of steel structure engineering?
Resistant to 70 meters per second hurricane, steel structure wind resistance: steel structure construction light weight, high strength, overall rigidity, deformation ability. The weight of the building is only 1/5 of that of the brick concrete structure. Maintain the life and property effectively.
Q:Definition of large steel structures
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:Want to ask the steel structure workshop leakage, how to do? How do you do it?
With high elasticity waterproof coating, special high strength waterproof suture polyester fabric is strengthened. After the film is solidified, a complete waterproof layer is formed, the bonding is firm, the high elasticity is maintained, and the waterproof and steam permeable is easy, and the construction is simple. With bass waterproof system for easy water leakage parts of waterproof construction, strengthen the treatment, can ensure that the roof is no longer leaking water, ten years quality insurance.
Q:What is called a steel rivet?
In the 60 and 70s, high-strength bolts have not yet, welding technology is not as advanced as now, so many of the steel structure connections, by rivets, see the old movies, sometimes see.
Q:How can the steel structure be divided into Liang Hezhu?
Refers to the beam and shear wall are connected with both ends of the beam span ratio is less than 5 (see section 7.1.8 of the specific provisions of the "high regulation"); frame beam and frame column refers to both ends connected with both ends of the beam, or shear wall connected but not less than 5 higher than the cross beam.
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
Second mine buildings or third mine buildings for steel or reinforced concrete buildings, between the steel or reinforced connection meet the specification and use it as a lead line under the condition when the vertical pillar plays a lead role, can not meet the requirements of special spacing between deflectors the.
