<p>PURPOSE:To provide a new fire prevention measure engineering method and a fire prevention measure material to be used therefor for a through hole in fire prevention partition wall or a floor in a building so that a combustible coated piping material may pass through it. CONSTITUTION:This is a fire prevention measure engineering method of a through hole 4 in a building where a hole in which a step part of incombustible coating material 1a, 1, which have been divided into two and has a cross section of almost an arc of a circle protruding by a specified length, and provided with a step fitting in the through hole 4, is inserted through the gap formed by inserting a combustible coated piping material into the through hole 4 of a fire prevention partition wall or a floor or the like and the other end is clamped and filled with an incombustible joint material 7. The measure taken for the other ends of incombustible coating material 1a, 1b is to clamp it by making a part thereof protrude from the end by a band shape ring body 8 and fill the interior of the band shape ring body 8 with the incombustible joint material 7.</p> |
