[Chai Jin cable tray to recommend the star product - Bridge] cable tray cable tray load load into load, dynamic load and the additional load. Static load refers to the laying of cables in the cable tray types, root number, diameter of each weight / unit length of cable laying by different routes, respectively Lists Statistics. Dynamic load is the weight of the cable tray installation and maintenance during construction maintenance personnel. For lightweight cable tray, generally do not consider dynamic load, which does not allow the station (lines) on the bridge were galvanized tray Which is good, if you stop to consider who should be appropriately reduced span. Additional load refers only outdoor ice and snow loads, wind and electromagnetic force is formed, it is with the nature of the installation site of the region's natural weather conditions and charged body concerned, the design should be calculated based on various conditions. [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), is uniformly distributed load tray, ladder or cable tray load; q2-- consider cable laying or maintenance, the person's weight equivalent uniform load (kN / m2) how much money galvanized bridge, q2 values calculate the weight of people in general terms by p = 90kg. 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 prices fulcrum pitch galvanized bridge, consult the manufacturer of the sample data, cross-check the spacing and bridge models, until meet the load requirement.
