Construction and installation points of cable tray

Construction and installation points of cable tray

1. The cable bridge and the trunking route should be laid short, and should be laid along the wall, along the column or along the beam. The installation must be firm and reliable, horizontal and vertical, no distortion, no burr on the inner wall of the bridge, and complete accessories. The specifications of the columns, brackets and support arms are strictly configured according to the design drawings and bridge specifications.

2. The spacing of the fixed cable tray brackets is generally not more than 1.5m-2.0m. In the case of entering and leaving the junction box, box, cabinet, and turning, brackets shall be added within 500mm.

3. Before the installation of the cable tray, it should be coordinated with the civil engineering and plumbing, ventilation and air conditioning, to determine the intersection between the ventilation pipe and the water pipe. According to the principle of electric water, the cable tray is on the top, the water pipe is below, the bridge is at a high point, and it is installed above the corrosive liquid pipeline, below the heat pipeline.

4. For the common problems of cable tray construction, fully consider the installation requirements of the whole factory bridge, quality technicians timely compile the "cable bridge construction technology and control measures", and eliminate the objective factors affecting the process quality of the cable bridge in advance.

5. In the design of cable tray, the design of the drawings provided by the design institute is relatively simple, the installation dimensions and materials are not complete, and the professional construction department should take the initiative to arrange the personnel to carry out the drawing review in conjunction with the actual situation on the site, and partially modify the drawings from the cost and process. Optimize the construction plan in two aspects. At the same time, fully consider whether the bridge installation is in collision with the professional pipeline installation, whether the construction profession correctly reserves the embedded parts, etc., to avoid the phenomenon of rework in the later stage.

6. Pay attention to the human factors of improving the quality of the process, and specially organize the construction personnel to carry out the pre-process training to achieve the common habits of correcting the construction and improve the quality awareness.
