The installation of cable trays under fire pipes needs to meet specific safety requirements and specifications. These requirements include:
Safety assessment: A detailed safety assessment must be carried out to ensure that the bridge crossing the fire pipe will not affect its normal operation and will not obstruct the fire passage.
Compliance: Local building regulations, fire regulations and relevant standards must be complied with. If the relevant regulations explicitly prohibit the arrangement of the bridge under the fire pipe, it cannot be carried out.
Approval: In special circumstances, if it is necessary to cross the fire pipe, the approval and permission of the relevant departments must be obtained.
Fire prevention measures: Fire prevention measures must be taken, such as setting up fireproof partitions, blocking materials, etc., to prevent the spread of fire.
Installation location: Ensure that the bridge is located within the fire partition and avoid the installation location of fire protection equipment such as fire sprinklers and fire alarms.
Spacing control: The spacing between the bridge and the fire pipe is generally controlled at about 1 meter to meet the needs of installation and maintenance.
In general, it is generally not recommended for the bridge to cross the fire pipe to ensure fire safety. If there are special needs, it is necessary to ensure that all safety measures are strictly implemented and obtain necessary approvals.
