電纜橋架作為布線工程的一個配套項目,目前尚無專門的規范指導,各生產廠家的規格程式缺乏通用性,因此,設計選型過程應根據弱電各個系統電纜的類型、數量,合理選定適用的橋架。
As a supporting project of wiring engineering, there is no special specification and guidance at present, and the specification program of various manufacturers is lack of universality. Therefore, the design and selection process should reasonably select the applicable bridge according to the type and quantity of cables in each weak current system.
(1)、確定方向:根據建筑平面布置圖,結合空調管線和電氣管線等設置情況、方便維修,以及電纜路由的疏密來確定電纜橋架的最佳路由。在室內,盡可能沿建筑物的墻、柱、梁及樓板架設,例如在利用綜合管廊架設時,則應在管道一側或上方平行架設,并考慮引下線和分支線盡量避免交叉,如無其它管架借用,則需自設立(支)柱。
(1) Determine the direction: determine the best route of the cable tray according to the building layout, combined with the setting of air conditioning pipelines and electrical pipelines, convenient maintenance, and the density of the cable route. Indoors, it shall be erected along the wall, column, beam and floor of the building as far as possible. For example, when using the comprehensive pipe gallery, it shall be erected in parallel on one side or above the pipeline, and the downlead and branch line shall be considered to avoid crossing as far as possible. If there is no other pipe support, it is necessary to set up (support) columns by itself.
(2)、荷載計算:計算電纜橋架主干線縱斷面上單位長度的電纜重量。
(2) Load calculation: calculate the cable weight per unit length on the longitudinal section of the main line of the cable bridge.
(3)、確定橋架的寬度:根據布放電纜條數、電纜直徑及電纜的間距來確定電纜橋架的型號、規格, 托臂的長度,支柱的長度、間距、橋架的寬度和層數。
(3) Determine the width of cable tray: determine the model and specification of cable tray, the length of supporting arm, the length and spacing of strut, the width and layers of cable tray according to the number of cables laid, cable diameter and cable spacing.
(4)、確定安裝方式:根據場所的設置條件確定橋架的固定方式,選擇懸吊式、直立式、側壁式或是混合式,連接件和緊固件一般是配套供應的,此外,根據橋架結構選擇相應的蓋板。
(4) Determine the installation method: determine the fixing method of the bridge according to the setting conditions of the site, and select the suspension type, vertical type, side wall type or hybrid type. The connectors and fasteners are generally supplied together. In addition, select the corresponding cover plate according to the bridge structure.

(5)、繪出電纜橋架平、剖面圖,局部部位還應繪出空間圖,開列材料表。
(5) Draw the plan and section of the cable tray, and draw the space map and list the material list for some parts.
2、如與電力電纜橋架合用時,應將電力電纜和弱電電纜各放置一側,中間采用隔板分隔。
2. If it is used together with the power cable bridge, the power cable and weak current cable shall be placed on one side respectively, and the middle shall be separated by partition.
3、弱電電纜與其它低電壓電纜合用橋架時,應嚴格執行選擇具有外屏蔽層的弱電系統的弱電電纜,避免相互間的干擾。
3. When the weak current cable and other low-voltage cables share the bridge, the weak current cable of the weak current system with external shielding layer shall be strictly selected to avoid mutual interference.
1.2、電纜橋架安裝和橋架內電纜敷設,應按已批準的設計文件施工。
1.2 cable tray installation and cable laying in the tray shall be constructed according to the approved design documents.
1.3、由支、吊、托架支撐的托盤(槽)或梯架直線段、彎通非直線段組合而成,敷設電纜具有連續性的剛性結構系統,為電纜橋架。
The cable tray or tray is a straight-line support system rather than a straight-line support system.
