Second, use of fasteners use instructions:
All kinds of constructional fastener models applicable to construction projects, the outer diameter for Ф 48 mm steel pipe scaffold, derrick and templates support the use of steel pipe support, the fastening of intersection, for water conservancy, chemical industry, metallurgy, mining, railways and other infrastructure projects.
Three, use method
1, right-angle fastener: used for vertical steel pipe cross coupling clamp, two pipe horizontal and vertical bar connection of steel pipe scaffold right-angle fastener tighten, it should be in the bolt torque from 40 n · m (tight), ensure that the horizontal tube after receiving outside load does not produce decline phenomenon.
2, rotating fastener: for two arbitrary Angle steel pipe cross coupling tighten.Is the scaffold bracing and high-rise building the connection of steel pipe scaffold double column used torsion distance is the same as the right-angle fastener.
3, docking fastener: used for steel pipe butt joint, two are mainly vertical tube lateral extension of horizontal tube and diagonal bracing.
Four, the main technical parameters of fasteners
1, construction fasteners the GB944-88 "malleable iron" regulation, its mechanical performance is not lower than the requirement of malleable iron brand KTH330-8,
2, product inspection by GB2828-8 "counting batch-by-batch inspection sampling procedure and sample table of the secondary normal inspection specified in the sampling plan.
Three parts, construction fasteners activity can be flexible rotation, rotating fastener both rotation surface gap less than 1 mm.
4, the fastener grip the pole, the opening minimum distance of 5 mm.
Five, the attachment
