General provisions of fasteners Steel Works

General provisions of fasteners Steel Works

1, this provision applies to steel structure fabrication and installation of bolts, torsional shear type high strength bolts, high strength large hexagon head bolts, steel bolts ball grid nodes with high strength bolts and pop rivets, self-tapping screw, nail fasteners and other construction projects.
2, the fastener member connecting nodes and splicing joints should be tightened after the inspection of construction.
3, Hainan acceptance of qualified steel fasteners connecting node and a splice joint, the design should be required to file in a timely manner antiseptic and fire painting. Contact with corrosive media joint application of anti-corrosion materials such as putty closed.
4, steel structure fabrication and installation unit, Hainan steel should be the existing national standards "Construction Quality Acceptance of Steel Structure Engineering" GB50205 the relevant provisions of the anti-slip coefficient were high strength bolts connecting the friction surface test, the results should be consistent with design Claim. When the bolts connecting nodes by pressure or tension-type connector connection strength design, the test may not be anti-slip surface friction coefficient.
