[Chai Jin cable tray to recommend the star product - the bridge] Selection Procedure trays (1) to determine the width of the bridge, the number of layers, the anchor types and spacing, as well as the distribution of cable trays on each layer. (2) the calculation of each cable uniformly distributed load (kN / m2), initially identified bridge models, specifications. (3) according to the maximum overall cable uniform load value checking bridge strength. [Chai Jin cable tray to recommend the star product - the bridge] (11) in the horizontal, vertical and vertical trunking bridge in laying cable, the cable banding response. Four pairs of wire cable bundle with 24 to 25 pairs or more trunk cable, optical cable and other signal cables should be based on the type of cable, cable diameter, the cable core number splitting banding. Lashing spacing should not be greater than 1.5 m, the deduction should be evenly spaced fire bridge how to sell, an appropriate degree. (12) tray horizontal laying fire bridge, the support spacing is generally 1.5-3m, vertical laid stationary on the building isomers spacing should be less than 2m. (13) when the metal trough laid up in the following circumstances under shelf or hanger: groove joints; spacing 3m; 0.5m two-port trunking leave office; the corner. [Chai Jin cable tray to recommend the star product - the bridge] (4) draw bridge route galvanized fire bridge on the parallel figure to indicate the coordinates of the bridge start, end, turning point, branch point and lifting points or position size, elevation, if they can draw bridge laying isometric view, the material will be more accurate statistics. Straight line segments: Indicate the full-length, bridge layers, elevation, models and specifications. Turning points and branch points: indicate the turn-board use of models and specifications. Lifting segment: marked elevation changes, can also be a partial sectional view of the large drawing or representation. Galvanized fire bridge, cable tray preferred Chai Jin (certified), Liaoyuan fire bridge provided by the Tianjin Chai Jin cable tray Limited. Chai Jin Tianjin cable bridge Limited (www.tjcjdlqj.com) is Tianjin, metal building materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chai Jin leader in cable tray with the staff warmly welcome all inquiries negotiations to create Chai Jin cable tray a better future.
