Although the embodiments for carrying out the present invention have been described so far, the present invention should not be limited only to the above-described embodiments.
In the embodiment described above, a guide rail was exemplified as a frame member according to the present invention, but the present invention is not limited to this. For example, a horizontal frame (upper frame and lower frame) or a vertical frame constituting a frame attached along the edge of the opening of the building may be employed as the frame member according to the present invention. Further, for example, a horizontal frame (an upper frame and a lower frame) or a vertical frame forming a frame holding a face material such as glass may be employed as the frame member according to the present invention.

In the above-described embodiment, rivets were exemplified as the first and second fixing members according to the present invention, but the present invention is not limited to this. Other fasteners such as screws and bolts may be employed as the first and second fixing members according to the present invention. Further, the first and first fixing members may be configured with the same type of fasteners, or may be configured with different types of fasteners.

In the above-described embodiment, the first fixing member according to the present invention was provided above the second fixing member according to the present invention, but the first and second fixing members are provided The height position is not limited to this, and may be the same height position. In addition, as the first fixing member according to the present invention, if a fire is assumed in the outdoor space partitioned by the fitting 1, it may be provided at a position exposed to the outdoor space. If a fire is assumed in the space inside the room partitioned by 1, it may be provided at a position exposed to the space inside the room. Furthermore, at least one of the first and second fixing members according to the present invention may be provided two or more.

A fitting according to the present invention is a fitting that partitions a room from the outside, comprising an elongated frame member, a reinforcing member arranged inside the frame member to reinforce the frame member, and a room partitioned by the fitting. A first fixing member provided at a position exposed to one of the inner space and the outdoor space and fixing the frame member and the reinforcing member to each other, and a first fixing member provided at a position not exposed to the one space. and a second fixing member for fixing the frame member and the reinforcing member to each other.

Here, it is assumed that a fire breaks out in one of the spaces described above.
In this case, of the first and second fixing members, the strength of the first fixing member provided at a position exposed to the one space is weakened by flames and heat. On the other hand, the second fixing member provided at a position not exposed to the one space is less susceptible to flames and heat, and thus maintains its strength. When the temperature of the frame member and the reinforcing member rises due to the fire and thermal expansion occurs in the frame member and the reinforcing member, the difference in the amount of thermal expansion between the frame member and the reinforcing member causes the first and second fixation. Among the members, the first fixing member with weakened strength is broken first. As a result, the frame member and reinforcing member remain fixed by the second fixing member.
As described above, since the fixed state of the frame member and the reinforcing member is maintained by the second fixing member, the reinforcing member will not come off from the frame member, and the fireproof performance can be sufficiently maintained. can. Moreover, since it is not necessary to fix the frame member and the reinforcing member to each other at many points as in the conventional art, the manufacturing cost can be reduced.

In the present invention, the first fixing member is provided on the upper side of the second fixing member, which is easily affected by flames and heat. Therefore, when a fire breaks out as described above, the strength of the first fixing member can be weakened at an early stage by flames and heat. That is, it is possible to reliably break the first fixing member before the second fixing member depending on the thermal expansion of the frame member and the reinforcing member.

Further, according to the present invention, in the above fitting, one each of the first fixing member and the second fixing member is provided.
In the present invention, since one each of the first and second fixing members is provided, the number of fixing points between the frame member and the reinforcing member can be reduced to a minimum of two points, and the manufacturing cost can be most reduced. can.

Further, according to the present invention, in the above-described fitting, the one space is the space on the outdoor side.
In the present invention, since one of the above-mentioned spaces is an outdoor space partitioned by fittings, in the event of a fire occurring in the outdoor space, the above-described fireproof performance is maintained while reducing manufacturing costs. The effect of being able to

In addition, according to the present invention, the above-described fitting further includes a shutter curtain having a plurality of shutter slats, and the frame member is inserted with the plurality of shutter slats and guides the movement of the plurality of shutter slats. It is characterized by being a guide rail.
In the present invention, fittings are composed of a shutter device having the above-described shutter curtain and guide rail. Then, when a fire occurs as described above, the first fixing member breaks earlier than the second fixing member according to the thermal elongation of the guide rail and the reinforcing member, and the second fixing member The fixed state between the guide rail and the reinforcing member is maintained by the above. Therefore, the reinforcing member that restricts the plurality of shutter slats from protruding does not come off the guide rail, and the reinforcing member can prevent the plurality of shutter slats from protruding. That is, the fireproof performance can be sufficiently maintained.
In particular, if the second fixing member is positioned on the lower side where the load applied from the shutter curtain to the reinforcing member is the largest, the protrusion of the shutter slats described above can be suppressed satisfactorily. can.
