2. Description of the Related Art Generally, as a fireproof panel for a fireproof structure, there is JP-A-4-237756.

[0003]

However, in a fireproof panel having such a structure, under high heat, the front surface material and the back surface material are deformed in different directions by being pulled toward the heating side due to the difference in heat conduction. Due to this, a gap is created in the connecting part, and heat and flame leak from this part to the other side, and J
There was a defect that the test of IS-A-1304 for a fire resistant structure for 1 hour could not be passed.

[0004]

In order to eliminate such drawbacks, the present invention forms an inorganic board between the front end of the male connecting portion and the front end of the rear surface to improve mechanical strength, fire resistance and engagement force. It proposes a mounting structure for a fireproof panel which can pass the JIS-A-1304 fireproof structure for 1 hour test and which is surely engaged with the improvement.
