Product Description:

Description:
1.Length of the welding withnot indication, full welding should be applied
2.Seam without indication is fillet weld, height is 0.75t
3.The cutting angle without indication, radius R=30
4.Cutting angle not specified should be
5.The diameter of the hole for the bolt if not specified, D=22

Steel Structure:

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" (GB500182002) "Construction Quality Acceptance of Steel" (GB50205-2001) "Technical Specification for welded steel structure" (JGJ812002, 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.

Q:The exterior walls of steel buildings are colored steel plates, aren't they?
The base plate of the color steel plate is a cold rolling base plate, a hot-dip galvanized substrate and an electro galvanized substrate. The coating types can be divided into polyester, silicon modified polyester, PVDF two and vinyl chloride. The surface state of color steel plate can be divided into coated sheet, embossing plate and printing plate, color steel appliances widely used in construction and transportation industries, the construction industry is mainly used in steel plants, airports, warehouses and other industrial and commercial refrigeration roof of the building walls and doors, building color steel less.
Q:What is a steel beam?
Steel structure is mainly made of steel, and it is one of the main types of building structures. Steel is characterized by high strength, light weight and stiffness, so it is suitable for building large span and ultra high and super heavy buildings;
Q:What is the budget for steel structure?
It may seem a little complicated, but it's not difficult to analyze it carefully. After you calculate the area, multiply the thickness by the theoretical weight, then divide by 1000 to get the result that the unit is ton.
Q:How to calculate the steel structure quota?
Joints, bolts, or rivets are usually used between components or components. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:Does the steel structure belong to high-risk industries?
Involving high-risk chemicals (Public Security Bureau), fire control, occupational health, major hazard sources, environmental protection procedures should be handled accordingly, there are three simultaneous reports.
Q:In the steel structure, should be the first high-strength bolts after the end of the welding, or first screw, then welding after the end of the screw?
If it's a frame or a box type! Plug welding is a common practice! Most of the bolts are hinged, and the bolt and weld joint must be rigid!
Q:What is called steel structure?
The steel structure is made of shape steel, which is a component that can be pressed and drawn. It is used as the main structure of the steel structure.
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
The appearance of the weld is smooth and beautiful, and there shall be no welding defects, such as blowhole, undercut, flowing, welding failure, incomplete sealing angle and non sealing.
Q:What is the two steel structure?
It is in the range of a structure (referring to the main structure of the bearing component part) after the completion of construction construction, is relative to the supporting structure, non bearing structure, the steel structure of the retaining structure, such as structural column, beam and lintel, waterproof anti parapet, filling, capping, partition wall steel structure the.
Q:What does steel structure cross section L75*5 mean?
In the steel structure, except the angle steel, there are channel steel, C steel, I-beam, H steel, Fang Gang, fish plate and so on.
