电缆桥架安装的工作流程是什么?

室外电缆桥架安装应在电缆桥架托臂所在标高的钢结构立柱施工完成后进行,济南电缆桥架的桥架走向、标高,确定支架位置。 支架、托臂水平间距应不大于3m,垂直间距应不大于2m,支架与支架间距应相等。支架、托臂在立柱和钢结构上安装采用焊接,焊缝应饱满支架应牢固可靠,当结构为混凝土材质时,利用预埋钢板焊接或膨胀螺栓固定。
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.

当膨胀螺栓固定的桥架对强度有疑问时,需向设计等有关部门报告并经现场确认。电缆桥架的切割应使用无齿锯或钢锯切割。不得使用电、气焊切割。桥架开孔应使用电钻或开孔器开孔,管与桥架连接应用专用接头连接。桥架在锯割后应锉刀把切口处修整光滑、平整,钻孔后应修去毛刺。
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.
桥架在连接时应用专用连接板,连接螺栓应由内向外穿,螺母位于桥架外侧并用扳手紧固。 在电缆敷设前需要对桥架进行全面检查,在适当的部分进行绑扎固定前要进行绑扎确认,电缆敷设完毕后,电缆桥架及时盖好盖板。
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.
