It consists of a fire-resistant material such as fire-resistant cotton, fire-resistant cloth, etc. locked to each of the standing claws, and a supporting wire attached and fixed to the tips of the plurality of standing claws protruding from the surface of the fire-resistant material. Is characterized by.

"Examples of the Present Invention" Hereinafter, the present invention will be described in detail with reference to Examples shown in the drawings.

In the embodiment shown in FIGS. 1 to 7, reference numeral 1 is a refractory wall body formed of a thin and flexible metal plate, and both side surfaces of the refractory wall body 1 are bent substantially at right angles to side walls 1a, 1a. Are formed.

Reference numeral 2 is a standing claw fixed to the surface of the fire-resistant wall body 1 by spot welding or the like so as to project forward. The standing claw 2 is spot-welded to the fire-resistant wall body 1 as shown in FIG. It is composed of a fixed plate 3 which is fixed by means of, and a lower end portion of the fixed plate 3 which is bent substantially at a right angle, and a triangular claw body 5 in which concave portions 4 and 4 are formed on both side surfaces of the front end.

As shown in FIG. 6, the standing claw 2 may be a fixed plate 3 and a triangular claw body 5A formed by bending the lower end of the fixed plate 3 at a substantially right angle. good.

Further, as shown in FIG. 7, the standing claws 2 are fixed plates 3
And a lower end portion of the fixing plate 3 which is bent substantially at a right angle to form a triangular claw body 5A, and a bundling hole 6 formed in a portion near the tip of the claw body 5A for binding. You may use the thing.

Reference numeral 7 denotes a refractory material such as ceramics wool, rock wool, etc., which is pressed and fixed to the surface of the fire-resistant wall body 1, and a refractory material such as a fire-resistant cloth. By pressing the refractory material 7 against the fire-resistant wall body 1, The standing claw 2 bites in and is fixed to the fire-resistant wall body 1.

Reference numeral 8 denotes a wire net arranged so as to cover the surface of the refractory material 7. The wire net 8 is bound and fixed to the tip of the nail main body 5 of the standing nail 2 protruding from the surface of the fire resistant material 7 with a wire, Alternatively, it is fixed to the tip of the standing claw 2 by welding or the like.

The fireproof wall 9 thus configured is used when covering the joint portion 11 between the left and right skeletons 10 and 10A adjacent to each other as shown in FIGS. 8 and 9.

In this case, a plurality of anchor bolts 12 are used to fix both ends of the fire-resistant wall main body 1 to the parts of the right and left adjacent frames 10 and 10A near the ends.

Further, as shown in FIG. 10, hanging metal fittings 13 are attached to the upper part of the fire-resistant wall main body 1 at predetermined intervals, and the hanging metal fittings 13 are connected to the passage 14
It can be used as a fireproof curtain by being attached to the rail 15 provided on the upper part of the.

[Different Embodiments of the Present Invention] Next, different embodiments of the present invention shown in FIGS. 11 to 18 will be described. In the description of these examples,
The same components as those of the embodiment of the present invention are designated by the same reference numerals, and duplicate description will be omitted.

11 to 15 is different from the embodiment of the present invention mainly in that the refractory material 7 pressed and fixed to the surface of the refractory wall body 1 is protruded from the surface of the refractory material 7. The supporting wire 16 such as a metal wire or a wire is bundled and fixed to the tip of the standing claw 2 with a wire, or welded and fixed to form the fire resistant wall 9A. 9A is used to cover the joint portion 11 between the left and right skeletons 10 and 10A as shown in FIG.
It is used when covering the outer peripheral portion of the iron pillar 17 as shown in FIGS.

In the embodiment of FIGS. 16 to 18, the main difference from the embodiment of the present invention is that a plurality of standing claws 2A protruding on the surface are formed on the fire-resistant wall body 1 by press molding. By using the fire resistant wall body 1 formed in the above, the fire resistant wall 9B that is easy to manufacture and inexpensive can be obtained.

In the embodiment of the present invention described above, after the fireproof wall body 1, the fireproof material 7 and the wire net 8 or the supporting wire 16 are attached to form the fireproof walls 9, 9A and 9B, the fireproof walls 9, 9A and 9B are attached to joints, buildings and iron columns. However, the present invention is not limited to this,
After fixing the fire-resistant wall main body 1 provided with the standing claws 2 or 2A to the joints, the building or the iron pillar, press and fix the fire-resistant material 7 to the fire-resistant wall main body 1, and then cover with the wire mesh 8 or the supporting wire 16.
The metal wire 8 or the supporting wire 16 may be welded or fixed to the standing claws 2 or 2A protruding from the refractory material 7 by wire bonding or wire to form the fireproof walls 9, 9A, 9B.

"Effects of the Present Invention" As is clear from the above description, the present invention has the effects listed below.

(1) A fire-resistant wall body formed of a flexible metal plate, a large number of standing claws provided on the surface of the fire-resistant wall body, and a large number of the plurality of standing claws pressed to cover the surface of the fire-resistant wall body. It is composed of a fireproof material such as fireproof cotton and fireproof cloth locked to the standing claws, and wire meshes fixed to the tips of the plurality of standing claws that cover the surface of the fireproof material and project from the surface. Therefore, it is possible to efficiently prevent the movement and damage of the fireproof material such as fireproof cotton and fireproof cloth. Therefore, it can withstand long-term use.

(2) According to the above (1), since the flexible metal plate is used as the fireproof wall body, it can be easily deformed. Therefore, it can be easily installed.
