橋架及電纜作為機電安裝工程的重要部分，施工好壞直接影響工程整體質量，這里選取橋架及電纜工程驗收中屢見不鮮的施工問題，以供大家逐一對照引以為戒，提升質量管理水平。下面山東電纜橋架廠家為您解答

As an important part of the electromechanical installation project, the construction quality of the bridge and cable directly affects the overall quality of the project. Here we select the construction problems that are common in the acceptance of the bridge and cable project, so that we can learn from each other and improve the quality management level. Next, Shandong cable bridge manufacturer will answer for you

線管和橋架連接使用波紋管，且未可靠固定

Corrugated pipes are used for the connection between the line pipe and the bridge and are not reliably fixed

橋架間跨接線應連接在連接片兩端，不得接在連接片上

The jumper wire between bridges shall be connected at both ends of the connecting piece, and shall not be connected on the connecting piece

規范要求非鍍鋅電纜橋架間連接板的兩端跨接銅芯接地線，接地線小允許截面積不小于4㎜2。

The specification requires that both ends of the connecting plate between non-galvanized cable trays shall be connected with copper core grounding wire, and the small allowable sectional area of the grounding wire shall not be less than 4 mm2.

橋架間連接片兩端沒有跨接地線

There is no jumper wire at both ends of the connecting piece between bridges

橋架間跨接線應連接在連接片兩端，不得接在連接片上

The jumper wire between bridges shall be connected at both ends of the connecting piece, and shall not be connected on the connecting piece

【正確做法】

[Correct practice]

橋架間跨接線連接在連接片兩端，符合要求

The jumper wire between bridges is connected at both ends of the connecting piece, which meets the requirements

橋架三通處三個方向都有支架，符合要求

There are supports in three directions at the bridge tee, which meet the requirements

橋架內電纜敷設用電線綁扎，且敷設混亂

The cable laying in the bridge is bound with wires, and the laying is chaotic

規范要求電纜敷設嚴禁有絞擰、鎧裝壓扁、護層斷裂和表面嚴重劃傷等缺陷。

The specification requires that the cable laying shall be free from defects such as twisting, flattening of armor, breakage of protective layer and serious scratch on the surface.

【正確做法】

[Correct practice]

橋架內電纜敷設整齊、順直，無絞擰

The cables in the bridge shall be laid in order and straight without twisting

橋架中電纜有中間接頭

The cable in the bridge has an intermediate joint

橋架內電纜敷設混亂、無綁扎，支架螺桿過長，防火封堵不符合要求

The cable laying in the bridge is disordered, without binding, the support screw is too long, and the fireproof plugging does not meet the requirements

電纜橋架接地不符合要求，扁鋼未固定

The grounding of cable tray does not meet the requirements, and the flat steel is not fixed

導線裸敷在梯架內，線纜堆集沒有綁扎或綁扎不符合要求

The conductor is laid bare in the ladder, and the cables are stacked without binding or binding does not meet the requirements

電纜橋架跨越變形縫沒有補償裝置，連接片螺栓不全，接地跨接未連接

The cable bridge crosses the deformation joint without compensation device, the connecting lug bolts are incomplete, and the grounding jumper is not connected

規范要求直線段鋼制電纜橋架長度超過30m、鋁合金或玻璃鋼制電纜橋架長度超過15m設有伸縮節；電纜橋架跨越建筑物變形縫處設置補償裝置。

The specification requires that the length of steel cable tray in straight section is more than 30m, and the length of aluminum alloy or glass fiber reinforced plastic cable tray is more than 15m, with expansion joints; The compensation device shall be set at the place where the cable bridge crosses the deformation joint of the building.

鋼制橋架與鍍鋅橋架混接，且沒有連接片，底部開孔用螺栓連接，沒有跨接線

The steel bridge is mixed with the galvanized bridge, and there is no connecting piece. The bottom opening is connected with bolts, and there is no jumper wire
