By the way, when the purpose is to improve the fire protection performance, it is preferable to dispose the thermally expandable member outside the hollow portion exposed to the flame in order to accelerate the timing of thermal expansion of the thermally expandable member. . However, when the thermally expandable member is simply attached to the outer surface of the hollow portion, if the hollow portion is thermally deformed by being exposed to a flame, the thermally expandable member loses its support, which is desirable. Can not demonstrate the fire protection performance of
Therefore, it is conceivable to use a nonflammable or flame retardant mounting member.
Specifically, the mounting member is provided outside the hollow portion and mounts the thermally expandable member. And an attachment member is fixed to the reinforcement member provided in the said hollow part by fastening members, such as a screw, via the side wall part which comprises a hollow part.
However, in the case of the configuration as described above, since the resin side wall portion is interposed between the mounting member and the reinforcing member, when the side wall portion is melted by being exposed to the flame, The mounting member is inclined. That is, there is a problem that the direction of thermal expansion of the thermally expandable member is inclined from a desired direction, and the fire protection performance can not be improved.

  An object of this invention is to provide the fixture which can improve a fire-protection performance in view of the said situation.

  In order to achieve the above object, a fixture according to the present invention is a fixture that partitions the inside and outside of the room, and is a resin-made hollow portion formed of a plurality of side wall portions, and a nonflammable or flame retardant provided in the hollow portion. Reinforcing member, and a non-combustible or non-combustible mounting member for mounting a thermally expandable member which is provided outside the hollow portion and is expanded by being heated, and the mounting member includes the plurality of side wall portions The first fastening member is fixed to the reinforcing member via the first side wall portion, and a through hole is provided in the first side wall portion, and at least one of the reinforcing member and the mounting member is provided. The non-combustible or non-combustible position fixing portion which protrudes toward the other member and is located in the through-hole is provided on the member of (1).

The position fixing portion may be provided only on the reinforcing member, only on the mounting member, or on both the reinforcing member and the mounting member. In the following, for convenience of explanation, it is assumed that the position fixing portion is provided only on the mounting member.
According to the present invention, when the mounting member is inclined when exposed to a flame and the first side wall portion is melted, the position fixing portion provided on the mounting member abuts on the reinforcing member (the other member). Thus, the inclination of the mounting member can be suppressed. That is, it is possible to maintain the thermal expansion direction of the thermally expandable member in a desired direction.
Therefore, according to the fitting according to the present invention, the fire protection performance can be improved.

Further, the present invention is characterized in that, in the above-described fitting, the position fixing portion is in contact with the other member via the through hole.
In the present invention, the position fixing portion abuts on the reinforcing member (the other member) through the through hole formed in the first side wall portion. That is, no resin-made portion is interposed between the position fixing portion and the reinforcing member (the other member) at the manufacturing stage. For this reason, when it exposes to a flame and a 1st side wall part fuse | melts, the inclination of an attachment member can be prevented more reliably.

Further, according to the present invention, in the above-mentioned fitting, the fitting is a pull-type window including a frame and a sliding door provided slidably in the frame so as to open and close the frame, the hollow portion, The reinforcing member and the mounting member are provided on the door butt end of the shoji, and the frame is provided to the first side wall portion of the door butt end when the shoji is closed. It is characterized in that an opposing member is provided to face in the prospective direction of the fitting.
By the way, in the case of a sliding window, when exposed to flames, the facing members of the door end of the shoji and the opposing members provided on the frame (in the case of a sliding window, in the case of another sliding door combination or a sliding window) The gap between the frame and the frame tends to be a through hole, which greatly affects the fire protection performance.
In the present invention, the first side wall faces the facing member in the direction in which the fitting is expected. In other words, the mounting member and the thermally expandable member are provided in the gap between the rear end side weir and the opposing member. For this reason, when exposed to a flame, the thermal expansion of the thermally expandable member can close the gap between the buttocks and the opposing member, and the fire protection performance can be improved. It can be suitably realized.

Further, the present invention is characterized in that, in the above-mentioned fitting, the attachment member provided on the door butt side ridge is a smoke return member which is engaged with the opposing member.
In the present invention, the attachment member has a function as a smoke return member in addition to the function of attaching the thermally expandable member. For this reason, compared with, for example, the case where the two functions are provided separately, the number of parts can be reduced, and the improvement of assembly workability and the cost reduction can be achieved.

Further, according to the present invention, in the above-mentioned fitting, the hollow portion, the reinforcing member, and the mounting member are respectively provided on both the door butt end ridge and the opposing member, and the attachment provided on the opposing member The member is characterized in that it is a smoke return member that locks to the smoke return member provided on the door butt side weir.
In the present invention, the hollow portion, the reinforcing member, and the mounting member are respectively provided to the opposing member in addition to the door butt end ridge. For this reason, also in the facing member, it is possible to maintain the thermally expanding direction of the thermally expandable member in a desired direction, as in the case of the door butt side ridge. Therefore, when exposed to the flame, the thermal expansion of the thermally expandable members provided on the door butt side and the opposing member can more reliably close the gap between the door butt side and the opposing member. it can.
Moreover, the attachment member provided in the opposing member also has a function as a smoke return member in addition to the function of attaching the thermally expandable member, similarly to the attachment member provided in the door rear end ridge. For this reason, compared with, for example, the case where the two functions are provided separately, the number of parts can be reduced, and the improvement of assembly workability and the cost reduction can be achieved.

Further, according to the present invention, in the fitting described above, a plurality of the attachment members provided on the door rear side ridge are provided, and a plurality of the attachment members are continuously provided in the longitudinal direction of the door rear side ridge. At least one of the plurality of mounting members includes a fixing portion to which the thermally expandable member is attached on a surface facing the opposing member, and a protrusion of the fixing portion toward the opposing member from an edge of the fixing portion And the overlapping piece extending in the longitudinal direction, wherein the overlapping piece overlaps in the finding direction of the door buttocks with respect to the other attachment members continuously provided in the longitudinal direction. Do.
By the way, when a plurality of attachment members are provided in a row in the longitudinal direction of the door butt end ridges, gaps will be generated between the thermally expandable members attached to the attachment members. The gap is a through hole, which may affect the fire protection performance.
In the present invention, at least one of the plurality of attachment members is an overlapping piece overlapping in the direction of finding the door edge with the other attachment members continuously provided in the longitudinal direction of the door edge. Prepare. Therefore, the gap can be closed by the overlapping piece. Further, by providing the overlapping piece, a high non-combustible or flame-retardant rigid portion is increased, so that the strength of the mounting member provided with the overlapping piece can be improved.

Further, according to the present invention, in the above-mentioned fitting, a lock is provided outside the hollow portion provided in the door rear side ridge, and the lock is provided on the first side wall portion of the plurality of side wall portions. A pedestal fixed to the reinforcing member by the second fastening member through the intersecting second side wall portion, and a lock piece supported rotatably or movably with respect to the pedestal, the pedestal Is fixed so as to protrude toward the first side wall along the second side wall, and the mounting member includes a facing portion that protrudes toward the facing member and faces the pedestal. I assume.
By the way, since the second side wall made of resin is interposed between the base and the reinforcing member, there is a possibility that the base may be inclined when the second side wall is melted by being exposed to a flame. is there. That is, there is a possibility that a lock piece such as a lock and the like may be detached from the receiving member such as the crescent receiver, and the space between the door butt end and the opposing member may be opened.
In the present invention, the pedestal is fixed so as to protrude toward the first side wall along the second side wall. Further, the mounting member is provided with a facing portion that protrudes toward the facing member and faces the pedestal. For this reason, when exposed to a flame and the 2nd side wall part fuses, when a pedestal inclines, an inclination of the pedestal concerned can be controlled because a mounting member (opposing part) contacts a pedestal. That is, it is possible to suppress that the lock piece such as the lock and the like is detached from the receiving member such as the crescent receiver and the space between the door butt end side and the opposing member is opened.

Further, the present invention is characterized in that, in the above-mentioned fitting, the position fixing portion is integrally formed with the at least one member.
In the present invention, since the position fixing portion is integrally formed on at least one member (only the reinforcing member, only the attaching member, or both the reinforcing member and the attaching member), for example, the position fixing portion is the at least one member The number of parts can be reduced as compared with the case where they are separately configured, and improvement in assembly workability and cost reduction can be achieved.
In particular, if the position fixing portion is formed on the periphery of the insertion hole through which the first fastening member is inserted by press processing such as drawing processing or extrusion processing, the position fixing portion may be formed simultaneously with the hole processing of the insertion hole. Since the processing can be performed, the processing can be easily performed.

Further, the present invention is characterized in that, in the above-mentioned fitting, the position fixing portion is configured separately from the at least one member.
In the present invention, since the position fixing portion is configured separately from at least one of the members described above, for example, the reinforcing member and the mounting are compared to the case where the position fixing portion is integrally formed with the reinforcing member and the mounting member. There is no need to form the position fixing portion on the member by press processing such as drawing processing or extrusion processing. Moreover, general purpose members, such as a washer, can be utilized as a position fixing | fixed part.

  According to the fixture of the present invention, the fire prevention performance can be improved.
