At the lower end of the refractory coating 22 and the lower end of the heat insulating material 30, metal parting plates 23, 24 are mounted separately. The pair of caps 33, 34 and the pair of parting plates 23, 24 are connected by screwing screws 33a, 34a from the pair of caps 33, 34 toward the heat insulating material 30.

Ceiling parting edges 25, 26 are attached to the parting plates 23, 24, respectively. A ceiling material 27 is attached to the ceiling parting edges 25 and 26. A pair of metal (for example, hot-rolled steel plates) baseboards 41 and 42 are attached to the floor 40 so as to be separated from each other. One skirting board 41 is fixed to the floor 40 by screws 41a. The other skirting board 42 is assembled to the skirting board 41.

A pair of caps 33, 34 and a pair of baseboards 41,
A core panel 50 is attached between the core panel 50 and the core panel 50.
The pair of caps 33, 34 and the core panel 50 and the pair of baseboards 41, 42 and the core panel 50 are fixed with screws. The core panel 50 has, for example, a cross-sectional structure in which an inorganic-mixed phenol foam resin foam 50a is sandwiched between painted hot-dip galvanized steel plates 50b via a urethane-based adhesive, and the upper portion 51 is fitted between the pair of caps 33, 34. At the same time, the lower part 52 is restrained by the pair of baseboards 41 and 42 and stands upright.

The upper part 51 and the side parts 50c, 50 connected thereto

The finished panel 60 has, for example, a cross-sectional structure in which a legally incombustible gypsum board 60a is sandwiched between cold-rolled steel plates 60b via an acrylic resin adhesive. here,
By attaching the finishing panel 60 to the core panel 50, a fireproof panel 65 is configured. As described above, according to the partition wall 10 according to the present embodiment, the fireproof panel 65 including the core panel 50 and the finish panel 60 is
Since it is structured to be attached to the heat insulating material 30 provided on the beam 21 side via the pair of caps 33, 34, the heat insulating material 3
The ceiling member 27 can be attached to the side of the fireproof panel 65 prior to the construction of the fireproof panel 65. Therefore, various operations can be performed without being restricted by the fireproof panel 65. Further, unlike the conventional case, the long-term curing of the fireproof panel 65 is not required.

The upper part 51 of the core panel 50 is made of the heat insulating material 3.
0, so that it is fitted between the pair of caps 33, 34 provided on the base plate 0.
A heat bridge is no longer formed between the heat insulating material 30 and the upper part 51 of the core panel 50.
The heat-insulating material surely exhibits the fire resistance function, and can satisfy the required performance of the fire resistance time of 1 hour or 2 hours.

Since a height adjusting member 53 is provided at a lower portion 52 of the core panel 50, the core panel 50 is
It is possible to press-contact the heat insulating material 30 on the side, so that the fireproof function can be reliably developed. In addition, each core panel 5
A metal plate-shaped connecting member 54 is disposed on both sides of the side connecting portion 53 between 0, and is fixed by screwing a tapping screw 57 into a bolt 56 that passes through each core panel 50. Side portions 50c, 50d of each core panel 50
Can prevent deformation of the surface plate and peeling of the adhesive due to heating.

Further, since the finishing panel 60 is supported by the column members 58 attached between the connecting members 54, the connecting portion 53 of each core panel 50 is covered by the finishing panel 60, and the flame from each connecting portion 53 Intrusion of such as is prevented by the finishing panel 60 and does not directly act on the connecting portion 53 of each core panel 50. Therefore, the thermal effect on the core panel 50 is reduced while the fireproof function of the finished panel 60 is maintained.

Further, since the core panel 50 is provided with a heat insulating material such as a calcium silicate plate on the upper portion 51 and the side portions 50c and 50d connected to the upper portion 51, the inorganic mixed phenol foam resin 50a is heated by heating. The generated water vapor is blocked by these heat insulating materials, and it is possible to exhibit fire resistance performance for a long time. 5 and 6 show a partition wall 70 (corresponding to claims 1 to 4) according to the second embodiment of the present invention.

The partition wall 70 according to this embodiment is the same as the partition panel 10 according to the first embodiment.
It has improved thermal insulation performance. For this purpose, the following changes are made to the core panel 50A and the baseboard 41A in the fireproof panel 65A. The core panel 50A has an upper part 51,
The width of a heat insulating material such as a calcium silicate plate disposed on the side portions 50c and 50d connected thereto is increased. Also,
A heat insulating material 50e such as a calcium silicate plate is interposed between the inorganic mixed phenol foam resin foam 50a and the painted hot-dip galvanized steel plate 50b.

A heat insulating material 46 such as a calcium silicate plate is mounted in the pair of baseboards 41A. Other configurations are the same as those of the first embodiment. Next, a method of constructing the partition wall 10 according to the present embodiment will be described (corresponding to claim 5).

First, as shown in FIG. 7, a base material 22a of a refractory coating 22 is attached to a beam 21. Next, as shown in FIG. 8, a heat insulating material 30 is attached to the lower end of the base material 22a. As shown in FIG. 9, metal parting plates 23 and 24 are attached to the lower side of the base material 22 a and the heat insulating material 30 with a space therebetween. Two through bolts 31 and 32 are attached to the heat insulating material 30 in the vertical direction.

Next, as shown in FIG. 10, a refractory coating work is performed on the periphery of the beam 21 and the base material 22a.
Apply 2. Next, as shown in FIG.
24, the ceiling parting edge is attached, and this ceiling parting edge 2
Attach ceiling materials 27 to 5,26. Next, as shown in FIG. 12, on the lower end surface of the heat insulating material 30, a pair of metal caps 33, 34 are attached separately from each other. FIG.
As shown in the figure, screws 33a, 34
a into the heat insulating material 30 by screwing
0 is attached. A metal baseboard 41 is provided on the floor 40.
Attach. The skirting board 41 is, as shown in FIG.
Is fixed by driving screws 41a at predetermined intervals.

Next, as shown in FIG.
The core panel 50 is attached between the baseboards 3 and 34 and the baseboard 41. Then, as shown in FIG.
By operating the height adjusting member 53 provided on the upper part 2, the upper part 51 is attached to the caps 33, 3 so that there is no gap between the heat insulating material 30.
Push up to the root of 4. Next, as shown in FIG. 14, a metal baseboard 42 is attached to the back side of the core panel 50. At this time, the space between the lower part 52 and the pair of baseboards 41 and 42 is filled with rock wool 45 as shown in FIG. Thereafter, the caps 33, 34 and the core panel 50 and the baseboards 41, 42 and the core panel 50 are fixed with screws.

Next, as shown in FIG.
A metal plate-like connecting member 54 is disposed on both sides of the side connecting portion 53 between the zeros, and bolts 56 penetrating each core panel 50
The screw is fixed by screwing a tapping screw 57 into the hole. Next, as shown in FIG. 16, a pillar 59 for attaching the finishing panel 60 is attached to each core panel 50. The support members 59 are attached so as to be equidistant from the connecting members 54. As shown in FIG. 17, the support member 59 is provided with claws 58 for hooking the finishing panel 60.

Next, as shown in FIG. 18, a finishing panel 60 is attached. As described above, according to the present embodiment, after the fireproof coating 22 is applied to the beam 21, the ceiling material is attached to the parting edge connected to the parting plate attached to the heat insulating material 30, so before constructing the partition wall, A ceiling is formed. Therefore, unlike the related art, it is not necessary to form the ceiling material and the partition wall at the same time, so that a work space can be secured, and the work time and work time can be freely adjusted. In addition, since there is no partition wall, special curing is not required.
