[Problems to be solved by the device]

 As mentioned above, the pillars in the conventional fire-resistant partitioning device are made of inorganic refractory materials in consideration of fire resistance and fire resistance.However, such inorganic refractory materials have comparatively weak mechanical strength, particularly There is a problem in terms of strength when a pillar with a high height is made of such an inorganic refractory material, so the height of the pillar is limited. Therefore, the strut itself should be made of metal, and the outer surface of the strut made of metal should be covered with a strut cover made of an inorganic refractory material to simultaneously satisfy both mechanical strength, fire resistance, and fire resistance of the strut. Is considered. However, when the outer surface of the metal strut is covered with an inorganic refractory strut cover in this manner, not only is the inorganic refractory strut cover attached to the metal strut, but also It is very difficult to screw the joint receiving metal fittings, and at the same time, if the holes are made in the inorganic refractory strut cover and screwed, the strength of the strut cover itself also becomes a problem.

In view of the above points, the present invention does not provide a fireproof partitioning device having a strut structure having sufficient strength as well as fire resistance and fireproof required as a fireproof partitioning device, and at the same time easy assembling work. It is what
