Examples include noncombustible boards such as gypsum board, calc board, and flexible board. In addition, the refractory material constituting such refractory material layers 3 and 4 contains cutting waste and crushed products produced when manufacturing the semi-incombustible or higher foam constituting the heat insulating core layer 2 as aggregate. You can also Note that the amount of the pulverized product mixed is not particularly limited as long as the fluidity is not lost. A fireproof partition wall panel having such fireproof material layers 3 and 4 is further lightweight and has improved fire resistance. Further, the fireproof material layers 3 and 4 may be made of a combination of different types of fireproof materials, such as one made of gypsum board and the other made of nitrogen-based noncombustible board.

In the present invention, the heat insulating core material layer 2 is formed of a foam whose main component is a vinyl chloride resin containing an inorganic filler or a chlorinated vinyl chloride resin, so that there is no space between it and the fireproof material layers 3 and 4. The adhesive interposed in the heat insulating core material 2 bites into the cells (void portions due to foaming), and the adhesion between the fireproof material layers 3 and 4 and the heat insulating core material 2 is good. In addition, the heat insulating core material layer 2 and the fireproof material layer 3
, 4, the heat insulating core material layer 2
Alternatively, the surfaces of the fireproof material layers 3 and 4 may be roughened, or anchor bolts penetrating the front and back surfaces of the heat insulating core layer 2 may be provided.

At this time, it is preferable to provide a reinforcing material 6 such as a reinforcing bar in the mortar 5 to improve the rigidity of each panel joint.

にはモルタル充填用の空間を形成する必要はない。Furthermore, for example, the joint portion 10 is
As shown in Figures 4-6, fittings may be used to interconnect adjacent refractory partition wall panels. In the specific example shown in FIG. 4, a convex metal fitting 7a is attached to one heat insulating panel 1, and a concave metal fitting 8a that engages with this convex part is attached to the other heat insulating panel 1. In this case, the metal fittings 7a,
Since the panels 1 can be connected to each other simply by fitting the panels 8a together, the assembly work becomes very simple. Further, in this case, there is no need to form a space for filling mortar at the abutting ends of the heat insulating panels as in the specific example shown in FIG.
【００１８】さらに、図５に示すように、凸状金具７ｂ

という利点がある。Furthermore, as shown in FIG. 5, a convex metal fitting 7b
may be configured to be sandwiched between the refractory material layers 3 and 4. In this case as well, not only is the assembly process simple, but
Since the part of the metal fittings that can be seen from the outside is small, it has the advantage of looking good.

It may be configured such that the end portions of the refractory material layers 3 and 4 are attached so as to cover the end portions of the refractory material layers 3 and 4. In this case, the fitting metal fittings 7c,
Since the size of 8c can be made relatively large, the strength of the joint portion 10 can be increased.
