Complete rail joints after laying a good composite rubber plate positioned on the track adjustment and bolts, clips and other parts in place, so that the bottom flange plate tight towel rail, then install plate, spring washers, tighten the nut to the rubber platen tongue compression is about 2-3mm.
Rail mounting tolerance requirements:
Centerline of the track position deviation ≤ 5mm; Track top elevation difference ≤ 5mm; The distance between the Plant transverse same position relative to the top surface of two tracks elevation difference; The distance between the two rails centerline deviation ≤ 5mm; Pillars ≤ 10mm Other office ≤ 15mm; Plant expansion joints using four-hole plate rail links. Steel tracks 4kg / m, 38kg / m, 43 kg/ m, 50kg / m expansion joints can be flush joints, QU70, QU80, QU100, QU120 expansion joints with 45 oblique joints, slit width are 10mm.two rails centerline deviation ≤ 5mm.
