優れているから室内と室外や、隣接した室を断熱するこ
とができる。As the above-mentioned outer wall material and partition material, a plate material made of a resin-based heat insulating material is known, and since this plate material has excellent heat insulating performance, it can insulate the inside and outside of a room or an adjacent room.

る。However, when the above-mentioned plate material is not incombustible and is used as a frozen warehouse building having excellent fire resistance, an outer wall material and a partition material having a fire-resistant structure are constructed in advance, and the outer wall material and the partition material are formed on the surface of the outer wall material and the partition material. A heat insulating plate made of the above-described resin-based heat insulating material is attached later to form a fire-resistant heat-insulating outer wall or partition, or a molten heat-insulating material is sprayed on the surface of the outer wall material or the partition material to form a heat-insulating outer wall or partition as a heat insulating layer. .

う。[0005] As described above, this is a construction method in which an outer wall material and a partition material having a fireproof structure are constructed on site, and then a heat insulating plate is attached to the surface, or a molten heat insulating material is sprayed to form a fireproof heat insulating outer wall and a partition. This requires a large number of man-hours, which not only increases the construction cost, but also lengthens the construction period.

に延焼させる欠点があり、耐火性能が十分でない。However, the above-mentioned refractory and heat-insulating plate material is obtained by directly bonding a refractory plate made of a cement-based incombustible material and an insulating plate made of a resin-based heat-insulating material. It becomes heavy, and handling becomes troublesome. In addition, heat heated at a high temperature due to a flame at the time of a fire passes through a refractory plate made of a non-combustible material, and the compression heat blocked by a heat insulating layer at a junction with the heat insulating plate made of a resin-based heat insulating material further increases the temperature. This has the drawback of instantaneously spreading the heat of the heat insulating plate made of the resin-based heat insulating material, and the fire resistance is not sufficient.

と共に、軽量の耐火断熱板材となる。Accordingly, a lightweight fire-resistant heat-insulating plate material having excellent heat insulation and fire resistance is obtained.
【0050】第2の発明によれば、耐火断熱板材の両面
からの火災に耐えることができるから、外壁材、間仕切
り材など広い用途に用いることができる耐火断熱板材と
なる。According to the second aspect of the present invention, since the fire from both sides of the fire-resistant heat-insulating plate can be withstood, the fire-resistant heat-insulating plate can be used for a wide range of uses such as an outer wall material and a partition material.
【0051】第3の発明によれば、火災時等に接合材が
長時間に亘って融解・引火しない。According to the third invention, the joining material does not melt or catch fire for a long time in the event of a fire or the like.
