室外電纜橋架安裝應(yīng)在電纜橋架托臂所在標(biāo)高的鋼結(jié)構(gòu)立柱施工完成后進(jìn)行，濟(jì)南電纜橋架的橋架走向、標(biāo)高，確定支架位置。 支架、托臂水平間距應(yīng)不大于3m，垂直間距應(yīng)不大于2m，支架與支架間距應(yīng)相等。支架、托臂在立柱和鋼結(jié)構(gòu)上安裝采用焊接，焊縫應(yīng)飽滿支架應(yīng)牢固可靠，當(dāng)結(jié)構(gòu)為混凝土材質(zhì)時(shí)，利用預(yù)埋鋼板焊接或膨脹螺栓固定。
The installation of the outdoor cable bridge should be carried out after the construction of the steel structure column, which is located at the height of the bracket arm of the cable bridge. The bridge frame of the Ji'nan cable bridge is heading and elevation, and the position of the bracket is determined. The horizontal distance between bracket and bracket should not be greater than 3m, and the vertical spacing should not be greater than 2m, and the distance between support and support should be equal. The brackets and brackets are welded on the column and steel structure. The welds should be solid and reliable. When the structure is concrete, it is fixed by the buried steel plate welding or the expansion bolt.

當(dāng)膨脹螺栓固定的橋架對(duì)強(qiáng)度有疑問時(shí)，需向設(shè)計(jì)等有關(guān)部門報(bào)告并經(jīng)現(xiàn)場(chǎng)確認(rèn)。電纜橋架的切割應(yīng)使用無齒鋸或鋼鋸切割。不得使用電、氣焊切割。橋架開孔應(yīng)使用電鉆或開孔器開孔，管與橋架連接應(yīng)用專用接頭連接。橋架在鋸割后應(yīng)銼刀把切口處修整光滑、平整，鉆孔后應(yīng)修去毛刺。
When there is doubt about the strength of the bridge fixed by the expansion bolt, it should be reported to the relevant departments such as design and confirmed by the scene. The cutting of cable bridge should be done with toothless saws or steel saw. It is not allowed to use electric or gas welding. The opening of the bridge should be perforated by electric drill or opener, and the connection between the pipe and the bridge should be connected with a special joint. After the sawing of the bridge, the file should be trimmed smooth and smooth, and burrs should be repaired after drilling.
橋架在連接時(shí)應(yīng)用專用連接板，連接螺栓應(yīng)由內(nèi)向外穿，螺母位于橋架外側(cè)并用扳手緊固。 在電纜敷設(shè)前需要對(duì)橋架進(jìn)行檢查，在適當(dāng)?shù)牟糠诌M(jìn)行綁扎固定前要進(jìn)行綁扎確認(rèn)，電纜敷設(shè)完畢后，電纜橋架及時(shí)蓋好蓋板。
When the bridge is connected, a special connecting plate is used. The connecting bolts should be worn from inside to outside. The nut is located outside the bridge and is fastened with a spanner. The bridge should be checked thoroughly before the cable is laid, and the binding confirmation must be made before the appropriate part is fixed. After the cable is laid, the cable bridge will cover the cover plate in time.
