It is necessary to prepare a large number of standard dimensions depending on the shape and the like, which leads to an increase in cost. In addition, the conventional thermal expansion material has a problem that the surface area is small due to its shape, and the thermal reaction rate is correspondingly low. SUMMARY OF THE INVENTION It is an object of the present invention to provide a thermal expansion filler for through-holes in fire protection compartments, which has a low manufacturing cost, is easy to construct, and has a high thermal reaction rate.

止する。The thermal expansion material packed in the pouch is packed as a pouch without leaving a gap in, for example, a through hole. The pouch is relatively small, and the thermal expansion material packed therein is fragmented, so that it has a large degree of freedom in shape and can be packed in any gap. When a fire occurs, the fragmented thermal expansion material has a rapid thermal reaction, and thus expands quickly, closing the through hole and preventing the spread of the fire.

In addition, due to the fragmentation, the degree of freedom of the shape when packed in a small bag is increased. The material of the small bag may be a net shape, and the material may be a resin, a cloth bag or the like.
