[Chai Jin cable tray to recommend the star product -] tray tray tray cable bridge in the selection of cable tray in the general level of emissions is a single layer, so its installation bridge width b is: b = n1 (d1 + k1) + n2 (d2 + k2) + n3 (d3 + k3) + ...... n1, n2, n3 ...... isoform above the number of model specifications of the cable. [Chai Jin cable tray to recommend the star product - the bridge]. (2) When installing the horizontal position of the bridge laying cable tray, height from the ground is generally not less than 2.5m. When the bridge multi-laying, for cooling, maintenance, and anti-interference between the needs of the bridge layer should leave some distance cable bridge in parallel with the various pipe laying, its spacing shall comply with the relevant requirements. (3) the quality hangers hanger cable tray installation shall comply with the relevant technical standards when the current level of laying cable tray, support span is generally 1.5 ~ 3m a try when laying cable tray vertical standards, fixed spacing of not more than level between two adjacent bridge corbel 2m height difference should not be greater than 10mm, two adjacent vertical deviation bridge corbel vertical midline should not exceed 20mm. [Chai Jin cable tray to recommend the star product - Bridge] checking the formula: Q = q1 + q2 using the formula: q1 - Cable uniform load (layers of uniform load of maximum value) (kN / m2) cable tray, uniformly distributed load is a tray, ladder or cable tray load; q2-- consider cable laying or maintenance, the person's weight equivalent uniform load (kN / m2), calculate trough q2 values cable bridge, people generally based on the weight of p = 90kg dollars. Said the concentrated load and uniform load bending moment 2 by Maximum bending moment equal conditions shown in translation: Let pι / 4 = q2ι2 / 8 则 q2 = 2p / ι∵P = 90kg∴q2 = 180 / ι where: P --1 people load (kg) ι - 1 support points spacing (maximum value if the fulcrum distance range) (m) q2--1 human equivalent uniform load (kg / m) based on the preliminary determine the bridge models, specifications and fulcrum distance cable tray installation, consult the manufacturer of the sample data, cross-check the spacing and bridge models, until meet the load requirement.
