[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] how to take deflection deflection given, also no clear provisions in the area obviously should consider reducing the burden around the degree, which means that the amount of steel will be a corresponding increase in fire bridge Therefore fire bridge much money, as long as the full use of the maximum allowable stress calculation steel fire bridge Which is good, and to ensure adequate fire safety factor of how to sell the bridge, the general maximum deflection of the span (distance between support points) than take 1/250 ~ 1/150 is appropriate. Expansion and contraction problems. [Chai Jin cable tray to recommend the star product - Bridge] 1.3 tray, trunking and hangers for use in corrosive environments, corrosion-resistant materials should be used for manufacturing rigid. Or take anti-corrosion treatment, anti-corrosion treatment should meet the requirements of the project environment and durability. For corrosion resistance demanding or requiring a clean place, should use aluminum cable tray. 1.4 bridge in the fire safety requirements of sections available in cable ladder, adding with a fire-resistant or flame retardant tray performance boards, nets and other material enclosed or semi-enclosed structure. How much fire bridge, Matsubara fire bridge, famous bridge brand Chai Jin Chai Jin provided by Tianjin cable bridge Limited.
