<P>PROBLEM TO BE SOLVED: To provide an attachment structure and attachment method of an indicator, allowing the indicator to be easily retrofitted to wall material in a state to secure fire resistance. <P>SOLUTION: An attachment frame 7 is attached to edges of an opening 5a on a surface of a wall material 5. A fireproof box 12 is inserted to the opening 5a, so that a box flange part 12b arranged on an outer peripheral part of the fireproof box 12 comes in contact with the attachment frame 7. An indicator 1 is inserted to the fireproof box 12 that is inserted to the opening 5a, and a flange part 3c is attached to the attachment frame 7. Since the box flange part 12b is clamped between the attachment frame 7 and the flange part 3c, the indicator 1 can be easily retrofitted to the wall material 5 in a state to secure fire resistance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
