What problems should be paid attention to when erecting trough cable tray?
The manufacture of the Cable tray supplier should meet the requirements of the slope of the building, and the bridge within the wall of the arc building should meet the requirements of the arc of the building.
The bridge frame and the bridge support are connected by the connecting plate, and the connecting bolts are made of semicircular head bolts.
The bridge is not allowed to carry people during the installation process, if the site conditions are really necessary, it is necessary to ensure that there are safety facilities on the bridge to carry people.
When the bridge is used as the grounding trunk, each end of the bridge shall be connected (in parallel) with 16mm2 soft copper wire to communicate with the main grounding line.
Fire-resistant or non-flammable plates, nets and other materials can be added to cable ladders and trays to form a closed or semi-closed structure, and fireproof coating can be applied to the bridge frame and its support frame.
Considering the beauty of the building and convenient maintenance, the public space without ceiling can be installed against the wall, column support or lower chord members of the roof truss.
The bridge span materials shall be constructed in accordance with the design requirements.
The galvanized bridge can also use the galvanized connecting plate as the span connection, connect the bridge as a whole, install galvanized spring washers on the two connecting bolts at both ends of the connecting plate, and strictly prohibit the nut grounding crossover on the bridge connecting plate.
When the straight line segment is more than 30 meters, the trough cable bridge is provided with a compensation device, and the discontinuous ends of the bridge are bridged with soft copper wires, leaving a telescopic margin.
At least two places on the Cable tray supplier are reliably connected to the main ground wire.
Inspection and acceptance content: cable tray installation must seriously do a good job of quality self-inspection and mutual inspection, pay special attention to whether the hanger is missing and firm, whether there is deformation and distortion, whether the telescopic compensation is missed, and whether the span grounding meets the requirements.
The above introduces to you the problems that need to be paid attention to in the installation of trough cable tray, which is widely used in the construction industry, so you must master the matters needing attention in the installation of bridge tray.
