<p><P>PROBLEM TO BE SOLVED: To provide a frame body for penetrating a fire protection compartment, capable of simplifying an attachment work as much as possible, easily dealing with a change in the size of a penetration opening when a cable rack is made to penetrate through the penetration opening opened at a hollow wall, and realizing an efficient attachment work and a good appearance regardless of technique familiarization of a worker in the structure for penetrating the cable through a partitioning wall made by concrete. <P>SOLUTION: This frame body covers a surrounding edge on both end sides of the penetration opening from an inner portion of the penetration opening of the compartment. The base plate 10 can be divided and can cover the opening edges at the upper/lower and right/left of the penetration opening from the inner portion of the penetration opening respectively on one end side of the penetration opening. An auxiliary base plate 20 can be divided which is combined so as to be slid in the other end direction of the penetration opening to the base plate 10, and can cover the opening edges at the upper/lower and right/left of the other end of the penetration opening. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
