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:What does "PD140*4" and "PL12*150" mean in the steel structure drawing?
Steel structure engineering is mainly made of steel, and it is one of the main types of building structures. Steel is characterized by high strength, light weight, overall rigidity and deformation ability, so it is suitable for building large span and ultra high and super heavy buildings;
Q:What are the protective coatings for steel structures? Do they need to be tested and sampled?
The main protective coatings for steel structure are protective primer, intermediate paint, finish coat and fireproof coating for steel structure. Mainly primer, fire retardant paintIn testing, primer, intermediate paint, finish coat and fireproof coating are required before entering. After construction, fire retardant coatings for steel structures need to be tested on-site (compulsory). Some protective paint also need on-site inspection (see supervision or design, etc.).Sampling should be representative and stir well. Take the amount of each test unit requires different paint class probably take 500-1000ml can. Fire retardant paint, if it is a thick powder, take at least 1500g. In general, we should take more, because the inspection unit to retain part of the original.Sampling and testing are witnessed and non - witnesses, it is best to notify the supervisor to the scene.
Q:Is the floor of the steel structure slab cast-in-place or steel?
Steel structure is mainly made of steel material, and it is one of the main types of building structure.
Q:How much is the cost of the floor bearing plate of the steel structure?
Just see this quiz information, Hello, steel structure, floor bearing plate models are different, the price per square meter is also different, generally open at around 50 yuan, closed at around 70 yuan.
Q:I want to make light steel structure. What tools do I need?
Another major content of the construction of steel structure is welding. The field welding equipment is mainly manual welding. As the labor costs are increasing day by day, in order to improve the efficiency, the gas shielded welding is becoming more and more popular at the installation site. Welding auxiliary equipment is the drying equipment of welding rod: drying machine.
Q:How are the steel structures single, multi story and tall, super high-rise?
Super Tower: refers to buildings over 40 meters above 100 meters in height.
Q:How can steel structures be made from bolts or bolts? High strength bolts are generally used for installation or production?
The high-strength bolt is used to calculate the force of the bolt group, and is also used for node calculation.
Q:What kind of steel is used in steel structure?
It depends on the kind of steel structure. There are thousands of kinds or even thousands of kinds of steel. General steel construction refers to the construction of steelIf the construction of steel, then basically steel Q235, Q345, Q390, Q420 four kinds of steel. Q235 is plain carbon steel. The latter three are low alloy steels. Corrosion depends on the structure of the steel structure and the use of parts, ships, viaducts, a corrosion resistant period of more than 20 years, but not up to this standard, foreign countries are basically sprayed aluminum and zinc sprayed. Antiseptic method. The tall tower structure of the TV tower mast varies from 10 to 20 years. The general steel structure must basically be more than 5 years.
Q:What are the raw materials of steel structure?
In the early stage of steel structure engineering, we should pre bury and embed the steel bar, that is, the anchor bolt. The material of the anchor bolt is Q235B. There are big and small.
Q:Housing cost of civil steel structure
Want to do high-rise residential steel structure also needs a long time in the domestic steel structure at present is industrial plant or self light steel villa type, or a certain first high-rise steel structure of high-rise residential can really do very little the price factor is part of the reason the other hand is the global scope for steel structure high-rise residential fire safety, maintenance cost and technology has not been able to reach. At the same time, the domestic people's knowledge of the steel structure residential is still relatively small, and the popularization of steel structure housing also needs a process.
