MG0616 Rotary fastener

MG0616 Rotary fastener Construction Steel Scaffolding Fasteners Institute under the National Building Mechanization design drawings, according to GB15831-1995 standards for manufacturing, their use as follows: 1) Model Specification: Cross fastener MG0616 2) use Model construction fasteners suitable for various types of construction, the outside diameter Φ48mm steel scaffolding, derricks, templates, such as the use of the steel supporting the fulcrum, the intersection of fastening, for water, chemical, metallurgy, mining, railways and other infrastructure projects also apply . 3) use Cross fasteners: steel pipe used for vertical cross-link two fastening, steel vertical rods and horizontal scaffold tube right-angle fastener fastening connection, it should bolt from the torque (tightening level) 40N · m, to ensure horizontal tube by the external load in the fall after the phenomenon does not produce. 4) Main technical parameters 1, construction fasteners with GB944-88 "Malleable Iron" requirement, not less than the mechanical properties of malleable cast iron grades KTH330-8 requirements 2, product testing Junan GB2828-8 "batch inspection Sampling procedures and sample forms" in the normal provisions of the second check sample program. 3, construction fasteners activities can be flexible and rotating parts, rotating coupler gap of two rotating surfaces are less than 1mm. 4, fastener clamp steel pipe, the openings of the minimum distance 5mm. 5) Annex T-bolts, nuts, washers, rivets are outsourcing parts factory, but factory procurement of "procurement control procedures" for acquisition and to ensure its quality. T-Bolt: M12 Length 75mm (GB196-81) Nut: M12 on the edge width of 22mm, thickness 14mm (GB196-81) M12 flat washer: thickness 2.5mm (GB95-85) Center of rotation rivet: Φ14 Round head rivets: Φ8 (GB876-86)
