By the way, in the double sliding window described in Patent Document 1, as a reinforcing member arranged in the hollow portion of the inner meeting frame, a member extending over the entire length from the upper end portion to the lower end portion of the inner meeting frame is used. It is difficult to reduce costs because reinforcing materials must be prepared each time according to the length of the stile.
It is also conceivable not to place the reinforcing material in the hollow part of the inner joining frame, but in this case, the inner joining frame may warp due to the heat of the fire, and this warping may occur in the inner joining frame. If it is closed, a gap is formed between the outer and inner stiles, and flames and the like may enter through this gap, resulting in a decrease in flame shielding performance.

A lock receiver 92 is attached to the outer stile 34 to which a lock 91 of the crescent lock 9 as a lock device is hooked.

A reinforcing member 51 having a substantially U-shaped cross section for reinforcing the outer joining frame 34 is arranged in the hollow portion 345 of the outside joining frame 34 described above. The reinforcing member 51 is made of a metal material having a higher strength than the outer joining frame 34, and is made of steel in this embodiment. The reinforcing member 51 extends in the Y-axis direction over the entire length of the outer joining frame 34, and includes a reinforcing prospective piece portion 52 on the inner peripheral side along the Z-axis direction and a reinforcing prospective piece portion on the outer peripheral side along the Z-axis direction. 53 and a reinforcing tab portion 54 along the X-axis direction.

The resin interior facing surface portion 691 is arranged to cover the interior facing surface portion 682 from the interior side. The resin outer peripheral projection surface portion 692 is arranged to cover the outer peripheral projection surface portion 683 from the outer peripheral side, and an engagement piece 692A formed at the outdoor end of the resin outer peripheral projection surface portion 692 is engaged with the continuous portion of the outdoor appearance surface portion 681 and the outer peripheral projection surface portion 683. are doing. The resin inner peripheral prospective surface portion 693 is arranged to cover the indoor portion 684C of the inner peripheral prospective surface portion 684 from the indoor side. is engaged with a continuous portion of the A rib 691A that abuts on the interior facing surface portion 682 is formed on the resin interior facing surface portion 691 so as to protrude to the outside of the room. A gap is formed between the resin outer peripheral prospective surface portion 692 and the outer peripheral prospective surface portion 683, and the resin inner peripheral prospective surface portion 693 is formed with ribs 693B protruding to the outer peripheral side. A space is formed between the inner circumferential projection surface portion 693 and the interior portion 684C.
The center-of-gravity position C of this inner meeting frame 64 is located near the partition piece 687 as shown in FIG. A pedestal 93 to which the lock 91 of the aforementioned crescent lock 9 is attached is arranged along the outer peripheral projection surface portion 683 of the inner meeting frame 64 . In this embodiment, the pedestal 93 abuts on the resin outer peripheral prospective surface portion 692 and is screwed to the first reinforcing prospective piece portion 102 of the fixed-length reinforcing member 101 to be described later by a fixing screw 81 as a fixture. A spacer 83 that maintains the interval between the resin outer peripheral projection surface portion 692 and the outer peripheral projection surface portion 683 is arranged at a portion between the resin outer peripheral projection surface portion 692 and the outer peripheral projection surface portion 683 and through which the fixing screw 81 passes.

In the outdoor hollow portion 645A of the above-described inner meeting frame 64, a fixed-length reinforcing member 101 having a substantially U-shaped cross section for reinforcing the said inner meeting frame 64 is arranged. The fixed-length reinforcing member 101 is made of a metal material having a higher strength than the inner joining frame 64, and is made of steel in this embodiment. The fixed-length reinforcing member 101 includes a first reinforcing prospective piece portion 102 on the outer peripheral side along the Z-axis direction, a second reinforcing prospective piece portion 103 on the inner peripheral side along the Z-axis direction, and a reinforcing prospective piece portion along the X-axis direction. The piece 104 is integrally formed. The first reinforcing prospective piece 102 is screwed to the outer circumferential prospective surface 683 with a fixing screw 82 as a fixture, and the reinforcing prospective piece 104 is continuous with the outdoor end of the first reinforcing prospective piece 102, The second reinforcing prospective piece 103 is continuous with the inner peripheral end of the reinforcing prospective piece 104 (the reinforcing prospective piece 104 is continuous with the outdoor end of the second reinforcing prospective piece 103). The reinforcement corner piece portion 104 that is continuous with the outdoor end portion of the first reinforcement prospective piece portion 102 and the second reinforcement prospective piece portion 103 is, for example, the reinforcement corner piece portion 104 connected to the first reinforcement prospective piece portion 102 and the second reinforcement prospective piece portion 102 . Compared to the case where the fitting piece 103 is continuous with the indoor end, the reinforcing fitting piece 104 is arranged at a position away from the center of gravity position C of the inner meeting frame 64 to the outside of the room. The reinforcing member 101 can further increase the cross-sectional strength of the inner joining frame 64, and the portion where the fixed-length reinforcing member 101 is arranged can be configured to be less likely to warp even in the event of a fire. In this embodiment, the first reinforcing prospective piece 102 has the same prospective dimension in the Z-axis direction as the second reinforcing prospective piece 103 , and is fixed to the pedestal 93 by a fixing screw 81 . In addition, the first reinforcing projection piece 102 fastens the resin outer circumferential projection surface portion 692 and the outer circumferential projection surface portion 683 together with the pedestal 93 , and is disposed in contact with the inner surface of the outer circumferential projection surface portion 683 . The second reinforcing prospective piece portion 103 is arranged on the outer peripheral side with respect to the outdoor portion 684B of the inner peripheral prospective surface portion 684 and is spaced apart from the outdoor portion 684B. We are working to improve fire resistance in the event of an outdoor fire. The reinforcing facing piece portion 104 is in contact with the interior surface of the exterior facing surface portion 681 . The first reinforcing prospective piece portion 102 and the second reinforcing prospective piece portion 103 are slightly shorter in the Z-axis direction than the outdoor portion 684B of the outer circumferential prospective surface portion 683 and the inner circumferential prospective surface portion 684, and the reinforcing prospective piece portion 104 is the outdoor part. The viewing surface portion 681 is slightly shorter in the X-axis direction than the portion that defines the outdoor hollow portion 645A. By making the length slightly shorter in this way, the insertability of the fixed-length reinforcing member 101 into the outdoor hollow portion 645A is improved.

As shown in FIG. 1, the length dimension L1 in the Y-axis direction of the fixed-length reinforcing member 101 described above is the distance between the upper fixing screw 81 and the lower fixing screw 81 that fix the pedestal 93 to the fixed-length reinforcing member 101. It is larger than the length L2 in the Y-axis direction of the fixed portion 95, which is the region between them, and is smaller than the length L3 of the reinforcing member 51 in the Y-axis direction. Within the range of this condition, for example, the length dimension L3 of the reinforcing member 51 (in this embodiment, the dimension equal to the length dimension of the outer joining frame 34 and the inner joining frame 64) is about 1100 mm to 1300 mm. , the length dimension of the fixed length reinforcing member 101 may be about 300 mm or 500 mm. Also, the length dimension L1 may be about 1/2 to 1/3 of the length dimension L3.
Since the fixed length reinforcing member 101 has a fixed length in this manner, it is possible to eliminate the need to prepare reinforcing members according to the length dimension L1 of various inner stiles 64 each time. It should be noted that, for example, it is possible to prepare several types of the length dimension L1, such as 300 mm and 500 mm, and in this case also, it is possible to reduce the time and effort required for preparation. Further, in this embodiment, the length dimension L1 of the fixed length reinforcing member 101 is equal to or greater than the length dimension of the pedestal 93 itself in the Y-axis direction.

In addition to the first thermal expansion refractory material 11 and the second thermal expansion refractory material 12, thermal expansion refractory material 13 may be appropriately provided at each location of the sliding window 1 described above.

In the above-described sliding window 1, as shown in FIG. A space between the indoor facing surface part 342 of the meeting frame 34 and the smoke return 7 is closed.
Here, since the outer joining frame 34 is reinforced over its entire length by the above-described reinforcing material 51, it is structured so that deformation such as warping is unlikely to occur even if it is subjected to heat in the event of a fire. On the other hand, in the inner joining frame 64, a fixed length reinforcing member 101 is arranged where the crescent lock 9 is attached. Therefore, deformation such as warping at the substantially central position is unlikely to occur. The structure is such that deformation such as warping is more likely to occur, and a case where such warping occurs is assumed.
Even if the above-described upper and lower portions are warped and the gap between the outer and inner joining frames 34 and 64 at these portions widens in the Z-axis direction, the outer and inner joining frames 34 and 64 will not be bent. Since the first thermal expansion refractory material 11 closes the position with the narrowest distance between the meeting frame 64, that is, the space between the interior facing surface portion 342 and the smoke return 7, the outer meeting frame 34 and the inner meeting frame 64 It is possible to preferably close the gap between. In addition, the second thermal expansion refractory materials 12 provided on the upper and lower ends of the inner meeting frame 64 thermally expand in the Z-axis direction toward the interior facing surface portion 342 of the outer meeting frame 34, In the above-described upper and lower portions, the space between the indoor facing surface portion 342 and the thick portion 681A of the outdoor facing surface portion 681 of the inner meeting frame 64 is closed at a position adjacent to the thermally expanded first thermal expansion refractory material 11. . As a result, the space between the outer joining frame 34 and the inner joining frame 64 can be blocked in a wider range.

[Modification]
In the above-described embodiment, the length dimension L1 of the fixed length reinforcing member 101 is larger than the length dimension L2 of the fixed portion 95 of the pedestal 93. The length dimension may be the same as the length dimension L2. In the above-described embodiment, the length L1 of the fixed-length reinforcing member 101 is equal to or greater than the length of the pedestal 93 itself in the Y-axis direction. The length dimension L1 may be smaller than the length dimension.

In the fittings of the present invention, the inner joining frame has a dividing piece portion that divides the hollow portion into an outdoor hollow portion and an indoor hollow portion, and the fixed-length reinforcing material is arranged in the outdoor hollow portion, The reinforcing end piece may continue to the outdoor end of each of the first reinforcing prospective piece and the second reinforcing prospective piece.
According to such a configuration, by arranging the fixed-length reinforcing material in the outdoor hollow part, compared with the case where the fixed-length reinforcing material is arranged in the indoor hollow part, the fixed part is more likely to be attached to the first reinforcing fitting part. The lock device to which the lock is fixed can be arranged at a prospective position near the outer shoji, and the lock device such as a crescent lock can be easily hung on a lock holder that can be provided on the outer shoji.
In addition, by configuring the reinforcing extension pieces of the fixed-length reinforcing material arranged in the outdoor hollow part to be continuous with the outdoor ends of the first reinforcement prospective piece and the second reinforcement prospective piece, for example, reinforcement Compared to the case where the facing piece continues to the indoor end of each of the first reinforcing prospective piece and the second reinforcing prospective piece, the center of gravity of the inner meeting frame is farther to the outside of the room. It is possible to provide a structure in which the reinforcing insert pieces can be arranged at positions, and the cross-sectional strength of the inner stile can be further improved by this fixed-length reinforcing material.

In the fitting according to the present invention, the first reinforcing prospective piece may be fixed to the outer peripheral prospective surface of the inner joining frame by a fixture.
According to such a configuration, in order to fix the first reinforcing prospective piece portion to the inner meeting frame, processing such as drilling is performed on the inner meeting frame, and the portion to be fixed of the lock device is reinforced. It is possible to concentrate the processing such as drilling holes for the inner joining frame to be fixed to the piece portion on the outer peripheral prospective surface portion (one surface portion) of the inner joining frame, thereby improving the workability.

In the joinery of the present invention, the first reinforcing prospective piece is fixed to the outer circumferential prospective surface of the inner stile by a fixture that fixes the fixed portion of the locking device to the first reinforcing prospective piece. good too.
According to such a configuration, the fixture for fixing the fixed portion of the lock device to the first reinforcing prospective piece and the fixture for fixing the first reinforcing prospective piece to the outer circumferential prospective surface of the inner stile are provided. Since it will be shared, the number of parts of the fixture can be reduced.
