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，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纜顯得類型、數量，合理選定適用的濟南電纜橋架。

As a supporting project of the cabling project, there is no special specification guidance at present, and the manufacturer's specification program is lack of universality. Therefore, the design and selection process should reasonably select the applicable Jinan cable bridge according to the type and quantity of cables in the 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較佳路由。在室內，盡可能沿建筑物的墻、柱、梁及樓板架設,如許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 better route of cable tray according to the building layout plan, combined with the setting of air conditioning pipeline and electrical pipeline, convenient maintenance, and the density of cable route. In the room, it shall be erected along the walls, columns, beams and floors of the building as far as possible. If it is possible to use the integrated pipe gallery for erection, it shall be erected in parallel on one side or above the pipe, and the down lead and branch line shall be avoided from crossing as far as possible. If there is no other pipe rack to borrow, 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 weight of cable per unit length on the profile of cable bridge trunk line.

(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 the cable tray: determine the model and specification of the cable tray, the length of the arm, the length and spacing of the support, the width and number of layers of the cable tray according to the number of cables laid, the diameter of the cable and the spacing of the cable.

(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，根據橋架結構選折相應的蓋板。

(4) Determine the installation method: determine the fixing method of the bridge according to the setting conditions of the site. 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 plane and section drawings of the cable tray, and the space map and material list for local parts.

如與電力電纜橋架合用時，應將電力電纜和弱電電纜各直一側，中間采用隔板分隔。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。更多相關內容就來我們網站http://m.ymmgjx.net咨詢！

If it is used together with the power cable bridge, the power cable and the weak current cable shall be separated on the straight side with a partition in the middle. When the weak current cable shares the bridge with other low voltage cables, the weak current cable of the weak current system with external shielding layer shall be strictly selected to avoid mutual interference.
