Steel structure engineering construction process process

1. Steel structure handmade arc welding process process

　　Work preparation → arc welding (flat welding, standing welding, horizontal welding, superstructure) → welding seam inspection

　　2. Tort -cut high -strength bolt connection process process:

　　Work preparation → select bolts and support → connect assembly → install temporary bolts → install high -strength snails

　　Bolt → High -strength bolt fastening → inspection and acceptance

　　3. The process process of large hexagonal high -strength bolt connection process:

　　Work preparation → Connectal assembly → Install temporary bolts → Install high -strength bolts → high -strength bolt fastening → check

　　acceptance

　　4. Steel roof frame production process process:

　　Processing preparation and feeding → part processing → small assembly (small fight) → Total assembly (total spell) → roof frame welding

　　Connect → Support connection board, bars, support corner steel assembly, welding → finished product inspection → rust removal, paint

　　,serial number

　　5. Steel roof frame installation process process:

　　Work preparation → roof frame group work → roof frame installation → connection and fixing → inspection, acceptance → rust removal, brush paint

　　6. Steel mesh structure assembly process process:

　　Operation preparation → ball processing and inspection → pole processing and inspection → small spelling unit → Zhongpin unit → welding → spell

　　Installer acceptance

　　7. Steel mesh structure installation process:

　　Put the line, test line → install the lower string plane network → install the upper string pour triangle network → install the downstrings orthopedic triangle network

　　Lian → Adjust, fastener → Install the roof hat head → branch welding and acceptance

　　8. Welding ball floor installation of high altitude combination method process:

　　Put the line, check the line → install the plane grid → install the stereo grid → install the string grid → the mesh

　　Body improvement → network frame high altitude together → network frame acceptance

　　9. Steel structure anticorrosive coating process process:

　　Base surface cleaning → primer painting → face paint painting → inspection and acceptance

　　10. Steel structural fire -resistant coating coating process process:

　　Work preparation → Fire -resistant coating ingredients, stir → spraying → inspection and acceptance
