CABLE TRAY A FUNCTION OF FIRE SPREAD PREVENTION AND FIRE PARTITION WALL THEREFOR

摘要

There is one cable trough a fire spread prophylactic function and a thermal foam to extinguish partition wall, be arranged to protect cable from flame thus by rapidly putting out a fire in the cable. A cable trough (10) with a fire spread prophylactic function includes that multiple drain holes (20) and one or more thermal foams extinguish subregion (30). Thermal foam extinguishes subregion and fixes unit (37) including a cable fixing unit (33), a partition body (31), a partition body, and extinguishes the thermal foam extinguishing fire-retarding paint or thermal foam of the powder of fire resisting. Cable fixing unit repairs multiple cables (2) and the gap as defined in formation one between cable. Partition body has a size to close the channel of cable trough. It repairs partition body to the fixed unit elasticity of partition body and cable fixing unit is fixed to cable trough. The thermal foam that thermal foam extinguishes the powder of fire-retarding paint or extinguishing fire resisting is applied to or is accommodated in cable fixing unit or partition body.
