[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expandable refractory zone which can be mounted vertically in a narrow gap between adjacent buildings.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 5, both edges 5 ′ and 5 ′ of the fire-resistant belt 5 formed by coating the fire-resistant fiber 1 such as rock wool with the fire-resistant sheet 3 are attached to the mounting member 8 via fasteners 7 such as bolts and rivets. It is sandwiched between the tip edge portion 8a and the fixing member 9, and the mounting member 8 fixes the base portion 8b to the building 10 and bends the tip edge portion 8a away from the building 10. Already known.

[0003]

However, in the above-mentioned conventional expansion refractory belt, both edges of the refractory belt 5 are provided between the mounting member 8 and the fixing member 9 via the fasteners 7 such as bolts and rivets. Since they are sandwiched, the following problems occur. The expansion refractory zone is inferior in design. Since it is difficult to find the insertion holes of the fasteners 7 such as bolts and rivets during assembly, the efficiency of assembly work is not improved. High number of parts and high product cost. Since both edges of the refractory zone 5 are merely fixed at the so-called "points" by the fasteners 7 such as bolts and rivets, the fixing is weak. The present invention has been made to solve such problems in the conventional expansion refractory zone.

[0004]

In the present invention as well, a refractory zone formed by coating refractory fibers such as rock wool with a refractory sheet is used, but the present invention improves the fixing means of the refractory zone as described above. It solves the problem.

That is, the present invention provides the following expansion refractory zone. (1) Fixing both edges of a fire-resistant zone formed by coating the fire-resistant fiber with a fire-resistant sheet to the tip edge portion of the mounting member,

An expansion refractory zone characterized in that each edge of the refractory zone is sandwiched between the curled portions (claim 1).

(2) Both edges of a refractory belt formed by coating a refractory fiber with a refractory sheet are fixed to the leading edge of the mounting member, and the mounting member bends the leading edge away from the building. With the expansion refractory zone whose base is fixed to the building, the tip edge of each mounting member is folded back toward the base of the mounting member on the side away from the building, and the tip edge of the mounting member approaches the mounting member. An expansion refractory belt (Claim 2), characterized in that a curl portion is formed by bending the curl portion into a curl portion, and the curl portion holds each edge of the refractory belt. In the present specification including the claims, the "base of the attachment member" is a portion of the attachment member fixed to the building, that is, Figs.
The lower part of the attachment member in 9 and 11 is meant.

(3) Both edges of a refractory belt formed by coating refractory fibers with a refractory sheet are fixed to the leading edge of the mounting member, and the mounting member bends the leading edge away from the building. In the expansion fireproof zone with the base fixed to the building together, the tip edge of each mounting member is folded back toward the base of the mounting member on the side away from the building, and the tip edge is mounted on the side closer to the building. An expansion refractory belt characterized in that a curl portion is formed by folding back the member in a direction away from the base portion, and each edge of the refractory belt is held by the curl portion (claim 3).

(4) Both edges of the refractory belt formed by coating the refractory fiber with the refractory sheet are fixed to the leading edge of the mounting member, and the mounting member bends the leading edge away from the building. With the expansion refractory zone so that the base is fixed to the building, the tip edge of each mounting member is folded back toward the base of the mounting member on the side away from the building, and the tip edge is further separated from the building. An expansion refractory zone characterized in that a curl portion is formed by folding back the mounting member in a direction away from the base portion, and each edge of the refractory zone is held by the curl portion (claim 4).

(5) Both edges of the refractory belt formed by coating the refractory fiber with the refractory sheet are fixed to the tip edges of the attachment member, and the attachment member bends the tip edges away from the building. With the expansion refractory zone so that the base is fixed to the building, the tip edge of each mounting member is folded back toward the base of the mounting member on the side away from the building, and the tip edge is further separated from the building. An expansion characterized in that a curl portion is formed by folding back the mounting member in a direction away from the base portion and bending the tip edge of the mounting member in a direction approaching the mounting member, and the curl portion holds each edge of the fire-resistant zone. Refractory zone (Claim 5).

(6) It is desirable to form a refractory zone drop-off prevention means on the surface of the curl portion that comes into contact with the fire zone.

[0011]

In the expansion refractory belt according to the present invention, each edge of the refractory belt is clamped by the curl portion formed by bending the tip edge portion of each mounting member. There is no need for a fixing member for fixing each edge of the refractory zone to the tip edge portion of the mounting member or a fixing tool such as a bolt or a rivet. Therefore, the expansion refractory belt according to the present invention is easy and efficient to assemble, and has a clean design. Further, since the curl portion of the mounting member sandwiches each edge of the refractory zone with a so-called “face”, the refractory zone is securely fixed to the mounting member. When the tip edge of the mounting member is bent in the direction approaching the mounting member, or when the device for preventing the falling of the refractory zone is formed on the surface of the curl portion that contacts the refractory zone, the refractory zone is more likely to fall off the curl portion. Certainly prevented.

[0020]

As described above, in the expansion refractory belt according to the present invention, the curl portion formed by bending the tip edge portion of each mounting member holds each edge of the refractory belt. A fixing member such as a bolt or a rivet for fixing each edge of the refractory belt as in the conventional expansion refractory belt to the tip edge portion of the mounting member is unnecessary. Therefore, the expansion refractory belt according to the present invention is easy and efficient to assemble, and has a clean design. Further, the expansion refractory belt according to the present invention has a small number of parts and is advantageous in terms of cost. Further, since the curl portion of the mounting member sandwiches each edge of the fire resistant zone with so-called “faces”, the fire resistant zone is securely fixed to the mounting member.

When the tip edge of the mounting member is bent in the direction approaching the mounting member, or when the refractory zone drop-off preventing means is formed on the surface of the curl section that contacts the fire zone, the curl section of the refractory zone is removed. Falling out is more reliably prevented.
