<p>PROBLEM TO BE SOLVED: To provide a fire spread preventing sheet and a method for its manufacture wherein the metal base in the fire spread preventing sheet can be grounded with ease and reliability without impairing the advantages of the fire spread preventing sheet. SOLUTION: A fire spread preventing sheet is wrapped around a cable rack 12 with cables 11 installed thereon, and is formed by bonding and laminating onto both the sides of a metal base 1 an insulating inner sheet 2 and an insulating outer sheet 3 which are flame-retardant, fireproof or incombustible and provided with insulating capability. In the fire spread preventing sheet, a metal face 2a is formed on at least part of the inner sheet 2 in contact with the cable rack 12 in order to electrically connect the metal base 1 with the cable rack 12 or a grounding metal wire 14 installed along the cable rack 12.</p> |
