<p><P>PROBLEM TO BE SOLVED: To provide a fire prevention member which is excellent in workability and costs, can easily deal with exchange of objects going through and their increase/decrease, and can reliably form a thermal insulation layer when a fire breaks out and its processing method with respect to fire prevention processing performed to a through part through which a cable or a pipe go on a fire prevention wall or floor demarcating a fire prevention section, such as a building. <P>SOLUTION: The fire prevention member includes a thermal expansion fire proof material in which an expansion material expanding by heating and a resin material are mixed and a thermal expansion fire proof member that is elastic and formed into a tube shape constructs a fire proof processing member. A holding member may be integrated with the thermal expansion fire proof member. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
