在安裝濟南電纜橋架時，要準確測量電纜橋架的各段長度和角度，采用電纜橋架廠標準件和工廠預制件，是為了減少現場切割橋架，保證工程質量。下面就來看看電纜橋架安裝過程中細節事項匯總。

When installing the cable tray in Jinan, the length and angle of each section of the cable tray shall be accurately measured, and the standard parts and factory prefabricated parts of the cable tray factory shall be used to reduce the cutting of the cable tray on site and ensure the project quality. Now let's take a look at the summary of details during the installation of cable tray.

敷設在豎井內和穿越不同防火區的橋架，應按設計要求位置，有防火隔離措施，電纜橋架在電氣豎井內敷設可采用角鋼固定。

The cable tray laid in the shaft and crossing different fire zones shall be provided with fire isolation measures according to the design requirements. The cable tray laid in the electrical shaft can be fixed with angle steel.

托臂是直接支承托盤、梯架單獨固定的剛性部件，托臂有螺栓固定可預埋螺栓，也可采用膨脹螺栓，也可卡接。

The corbel is a rigid part that directly supports the tray and the ladder and is fixed separately. The corbel can be fixed with bolts, embedded bolts, expansion bolts or clamped.

電纜橋架水平敷設時，支撐跨距一股為1.5-3m，電纜橋架垂且敷設時固定點間距不宜大于2m。橋架彎通彎曲半徑不大于300mm時，應在跨距彎曲段與直線段結合處300-600mm的直線段側設置一個支架、吊架。支、吊架和橋架安裝須考慮電纜敷設彎曲半徑滿足規范很小彎曲半徑。

When the cable tray is laid horizontally, the support span is 1.5-3m. When the cable tray is laid vertically, the spacing between fixed points should not be greater than 2m. When the bending radius of the bridge is not more than 300mm, a support and hanger shall be set at the side of the 300-600mm straight section at the junction of the span bending section and the straight section. For the installation of supports, hangers and bridges, it must be considered that the bending radius of cable laying meets the requirements of very small bending radius.

門型角鋼支架的安裝：梯型橋架沿墻垂直敷設，可使用門型角鋼支架，支架的固定應盡可能配合土建施工預埋；也可在土建施工中預埋開角螺栓，用開角螺栓固定支架；也可以采用膨脹螺栓固定。

Installation of gate type angle steel support: the ladder type cable tray is vertically laid along the wall, and the gate type angle steel support can be used. The support shall be fixed in coordination with the civil construction as far as possible; Open angle bolts can also be embedded in civil construction, and the bracket can be fixed with open angle bolts; Expansion bolts can also be used for fixing.

梯型角鋼支架的安裝：橋架沿墻、柱水平安裝時，托壁需安裝在異型鋼立柱上，而立柱要安裝在梯型角鋼支架上，使柱和墻上的橋架固定支架（或托臂）在同一條直線上。底架與門型架焊接時，焊角高度5mm。

Installation of ladder type angle steel support: when the cable tray is horizontally installed along the wall and column, the supporting wall shall be installed on the special-shaped steel column, and the column shall be installed on the ladder type angle steel support, so that the fixed support (or bracket) of the cable tray on the column and the wall is in the same straight line. When the underframe is welded with the portal frame, the weld fillet height is 5mm.

電纜橋架立柱側壁式安裝：立柱是直接支承托臂的部件，分工字鋼槽鋼、角鋼、異型鋼立柱;立柱可以在墻上、柱上安裝、也可懸吊在梁板上安裝。做法在混凝土可預埋鐵件；砌體可砌筑預制砌塊；也可以采用膨脹螺栓但須在混凝土強度C20或磚強度在MU10以上的磚砌體上。

Side wall installation of cable tray column: column is a component that directly supports the corbel, including channel steel, angle steel and special-shaped steel column; The column can be installed on the wall, on the column, or suspended on the beam and slab. Method: embedded iron parts in concrete; Masonry can be built with prefabricated blocks; Expansion bolts can also be used, but must be used on brick masonry with concrete strength C20 or brick strength above MU10.

電纜橋架應敷設在易燃易爆氣體管和熱力管道的下方，當設計無要求時，與管道的很小凈距，符合一般規定。更多相關事項的了解就來我們網站http://www.yeeones.com一起咨詢吧！

The cable tray shall be laid under the flammable and explosive gas pipe and heat pipe. When there is no design requirement, the clear distance between the cable tray and the pipe shall be very small, which shall comply with the general provisions.
