According to the layout of the building, the optimal route of the bridge is determined by combining the conditions of air conditioning pipelines and electrical pipelines, convenient maintenance, and the density of cable routing.
In the room, as far as possible along the wall, column, beam and floor of the building, when the integrated corridor is set up, it should be erected parallel to the side or above the pipe, and consider the downline and branch to avoid crossing as much as possible. If no other pipe frame is borrowed, it should be set up (Branch).
As a matching project of wiring engineering, there is no special guidance for the bridge. The specifications and programs of Shandong cable bridge manufacturers are lack of generality. Therefore, the design and selection process should be based on the type and quantity of the weak power system cables, and the suitable bridge should be selected reasonably.
According to the number of cables, the diameter of the cable and the distance between the cables, the type and specification of the cable bridge, the length of the bracket, the length and the distance of the support, the width and the number of the bridge are determined.
The cable weight per unit length on the longitudinal section of the main trunk line of the bridge is calculated. The fixed mode of the bridge is determined according to the setting conditions of the site. The suspension, erect, side wall or mixed type are selected, and the fittings and fasteners are generally supplied. In addition, the corresponding cover plate is selected according to the bridge structure.
