China Steel structure manufacturing - Al Wakrah Stadium of Qatar appeared in Qatar World Cup
At 0:00 on November 21, Beijing time
The 2022 Qatar World Cup officially opens
Having undertaken the Beijing Winter Olympics in China
Construction contractors of sports venues for several important international events
On the opening day of the World Cup
China steel structure is also in "another arena"
Actively participate in the World Cup
Inspired by local traditional culture and dhow
Design key marine elements
The roof is designed as an inverted sloop hull
The facade is tapered and inclined outwards
Large cantilevered eaves covered with metal cladding
The streamline white outline of the court is similar to a sail blown by the wind
With removable modular seat design, there are about 40000 seats
The company undertakes the processing, manufacturing and FOB delivery of some steel structures of the project
Fine management and strict control
The project components have strict quality requirements and high acceptance standards
Construction materials,Thin wall straight seam pipe (80 * 5-200 * 8)
The part plates are mainly 5-25mm thin plates,Material S355JR
European standard or American standard shall be adopted for welding
NDT shall be carried out according to American standard AWS D1.1
Small project components and many parts
And there are many space warp components
Including 23086 components
100 parts per ton of component
90% of the member end plate is not perpendicular to the member,Square tube cannot be sawed by numerical control cutting machine,Manual cutting only
A large number of support plates with different spatial angles
Height between 300-1000mm
It is difficult to weld components
Main welds and rib plate welds of steel members of the project
Adopt penetration weld
Large welding amount and easy deformation
The fabrication plant specially sets up a project welding team
Carry out targeted training and examination selection for welders
Refine the welding sequence of welds
Specify welding direction and welding process parameters
Take anti deformation measures such as fixing and baking in advance
Finally ensure that the audit and inspection pass smoothly
