Cable Bridge 5 Attention

(1) Determine the direction: according to the building layout, combined with the setting of air conditioning pipelines and electrical pipelines, convenient maintenance, and the density of cable routing to determine the best route of cable bridge. In the room, as far as possible along the walls of the building, columns, beams and floor erection, such as the use of comprehensive pipe gallery erection, it should be parallel to one side or above the pipeline, and consider the lead down and branch lines as far as possible to avoid crossing, if there is no other pipe frame to borrow, it is necessary to set up (branch) columns.
(2) Load calculation: calculate the cable weight per unit length on the longitudinal section of the main trunk line of the cable bridge.
(3) Determine the width of the bridge: according to the number of cables, cable diameter and cable spacing, determine the type and specification of the cable bridge, the length of the bracket arm, the length and spacing of the pillar, the width and the number of layers of the bridge.
(4) Determine the installation method: Determine the fixing method of the bridge according to the setting conditions of the site, choose suspension type, vertical type, side wall type or hybrid type, connectors and fasteners are generally supplied, in addition, select the corresponding cover plate according to the bridge structure.
(5) Draw the flat and section diagram of the cable bridge, and the space diagram should be drawn for some parts and the material table should be listed.
