Fixed support points should be set up on the bridge within 500mm of the corners and deformation joints of the junction box and cabinet, as well as the three ends of the T-joint. It is strictly prohibited to use electrical welding to cut supports and hangers; It is strictly prohibited to use wooden bricks to fix supports and hangers.
When the bridge is installed horizontally, the support span is generally 1.5-3m, and the spacing between fixed points is not more than 2m when laid vertically.
The bridge should be flat, without distortion or deformation, with no burrs on the inner wall, and all accessories complete
The bridge interface should be flat, and the joints should be tight and straight. After installing the slot cover, it should be flat, without any warping angles, and the position of the outlet should be accurate.
When laying inside the suspended ceiling, if it is not possible to access people, an access hole should be left.
All non conductive iron parts of the bridge should be interconnected and bridged to form a continuous conductor, and the overall grounding should be done; The grounding jumper between each section of the bridge is made of braided copper wire.
When the bridge passes through the deformation joint of the building, the bridge itself should be disconnected, and the groove should be overlapped with a connecting plate without the need for fixation. Compensation allowance should be left for the protective ground wire and the wire in the slot. Straight section steel bridges should conscientiously implement safety construction rules and regulations, strengthen the management of construction personnel, implement safety construction technical measures, inspect and supervise the safe operation of construction personnel, and achieve safe and civilized construction.
Organize construction personnel to learn construction standards and familiarize themselves with construction drawings, strictly follow the design and relevant regulations and standards for construction, inspect construction quality at any time, and promptly rectify any problems found.
The installation of scaffolding and the safety protection devices for electrical and mechanical equipment used on the construction site should comply with relevant safety regulations and be accepted before use.? Construction personnel should comply with the following regulations throughout the entire construction process:
It is necessary to comply with and implement relevant management systems for safe production and civilized construction, and accept the inspection and supervision of the construction unit's supervisory personnel. Safety helmets must be worn when entering the construction site, and safety belts must be fastened when working at heights.
When working in the control room switch room, it is necessary to have a supervisor present and carry out the work in the event of a power outage. Metal items such as watches, keys, lighters, pens, etc. should be removed, and insulated gloves and shoes should be worn.
When arranging and discharging cables, the consent of the supervisor should be sought in advance and carried out under the supervision of the supervisor.
After the construction is completed, the construction site should be cleaned up.
Safety Construction Management System
When entering or leaving the work area, it is necessary to register the time, number of people, and work content.
Construction personnel entering the construction site must wear work badges, safety helmets, and work clothes.
Smoking is strictly prohibited when entering the work area for construction.
When working in live working areas, it is necessary to wear insulated gloves and shoes.
