Description

  The present invention relates to a joinery that supports a sliding paper slidingly with an opening frame.

  In joinery used for building windows, there is a configuration using a shoji that holds a glass plate with a casing made of a metal casing such as aluminum. There is also a configuration using a shoji that holds a glass plate with a casing in which a resin casing such as a vinyl chloride resin is mounted on the indoor side of a metal casing such as aluminum. As this type of fitting, for example, there is a sliding window in which a shoji is slidably arranged with an opening frame.

  Patent Document 1 discloses a joinery including a shoji that holds a glass plate with a casing in which a resin casing is mounted on the indoor side of a metal casing. In this configuration, a reinforcing material is inserted into each of the hollow portions of the upper rod, the lower rod, the door rod, and the summon rod.

Japanese Patent No. 4072421

  Generally, the reinforcing material as described above is made of a metal such as steel or stainless steel. That is, in the configuration of Patent Document 1, since the reinforcing material is inserted into the hollow portions of all the upper, lower, left and right frames, it is possible to secure the fireproof strength when the joinery is subjected to a flame such as a fire or heat. However, in this configuration, since the reinforcing material is inserted into all the saddle materials, there is a problem that the weight of the shoji increases and the cost and the man-hour for adding the reinforcing material increase.

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a joinery that can ensure fire prevention performance while suppressing an increase in cost and weight.

  A joinery according to the present invention is a joinery in which at least one sliding paper holding a face material is supported by an opening frame so as to be slidable by a frame having an upper heel, a lower heel, a door heel, and a summon heel, The summoning bowl is provided with a first hollow portion into which a reinforcing material is inserted. At least, the wall thickness of the outdoor wall portion forming the outdoor-side finding surface is set on the door-end bowl. A second hollow portion thicker than the wall thickness of the wall portion forming the first hollow portion is provided.

  According to such a structure, since the said fitting has inserted the reinforcing material in the 1st hollow part of the summon bowl, the fireproof strength in the summit bowl which is not supported by the opening frame can be ensured. Furthermore, the joinery sets the plate | board thickness of at least the outdoor side wall part among the wall parts which form the 2nd hollow part of the door toe wall to be thicker than the plate | board thickness of the wall part which forms the hollow part of the summon bowl. That is, the door toe has a thick structure. Thereby, the door-end fence can ensure sufficient fire-proof strength without inserting a reinforcing material into the hollow portion or only inserting a lightweight and thin minimum reinforcing material. Therefore, in the joinery, fire prevention performance can be ensured while suppressing an increase in cost and weight of the frame and the shoji using the same.

  In the joinery according to the present invention, the second hollow portion of the door toe has a thickness of an opening side wall that forms a part of the opening groove for holding the face material, and the first hollow portion of the summoning ridge. It may be thicker than the wall thickness of the wall to be formed. If it does so, the said joinery can further raise the fireproof intensity | strength with respect to holding | maintenance of the face material in a door-end fence.

  The joinery which concerns on this invention WHEREIN: The structure by which the reinforcing material is not inserted in the 2nd hollow part of the said door-end fence may be sufficient. If it does so, the cost and weight of a frame and a shoji can be reduced further.

  In the joinery according to the present invention, at least a plate thickness of an outdoor side wall portion forming the outdoor side finding surface is thicker than a plate thickness of a wall portion forming the first hollow portion of the summoning basket. 3 hollow portions are provided, and at least a wall thickness of the outdoor side wall portion forming the outdoor side finding surface is larger than a plate thickness of the wall portion forming the first hollow portion of the summoning bowl in the lower rod. The structure provided with 4 hollow parts may be sufficient. If it does so, the said joinery will also become a thick-walled structure also about an upper collar and a lower collar. As a result, the upper and lower rods can ensure sufficient fireproof strength without inserting a reinforcing material into the third and fourth hollow portions or by inserting a light and thin minimum reinforcing material.

  The joinery which concerns on this invention WHEREIN: The structure by which the reinforcing material is not inserted in the 3rd hollow part of the said upper collar and the 4th hollow part of the said lower collar may be sufficient. If it does so, the cost and weight of a frame and a shoji can be reduced further.

  In the joinery according to the present invention, the summoning tub is provided with a fifth hollow portion along the indoor side of the first hollow portion, and one wall portion of the first hollow portion holds the face material. An opening groove may be formed, and the reinforcing material may not be inserted into the fifth hollow portion. If it does so, the said fitting can ensure sufficient fire-proof intensity | strength in the 1st hollow part of the outdoor side which forms the opening groove | channel which hold | maintains a face material. On the other hand, the joinery can achieve a balance between strength, cost, and weight by not inserting a reinforcing material into the fifth hollow portion on the indoor side that has little influence on fireproof strength and the like.

  In the joinery according to the present invention, the upper frame of the opening frame may have a hollow portion on the side opposite to the inner prospective surface on the shoji side. If it does so, the said fitting can relieve | moderate the influence of a flame, a heat | fever, or solar radiation in a hollow part, and can suppress producing a damage to the inner prospective surface side of the upper frame which supports a shoji.

  In the joinery according to the present invention, the upper frame has a rail for guiding the shoji projecting on the inner prospective surface, and the hollow portion includes a plurality of support walls provided on an extension line of the rail. It may be configured to be partitioned into spaces. If it does so, the said fitting can suppress the thermal expansion of the shoji at the time of a fire etc. with a support | pillar wall. As a result, a gap is hardly generated between the upper frame and the shoji, and the fireproof strength is further improved.

  A joinery according to the present invention is a joinery in which at least one sliding paper holding a face material is supported by an opening frame so as to be slidable by a frame having an upper heel, a lower heel, a door heel, and a summon heel, The summoning bowl is provided with a hollow portion into which a reinforcing material is inserted, and at least the wall thickness of the outdoor side wall forming the outdoor-side finding surface is at least equal to the hollow portion of the summoning bowl. A hollow part thicker than the plate thickness of the wall part to be formed is provided. According to such a configuration, the upper arm can secure a sufficient fireproof strength without inserting a reinforcing material into the hollow portion or by inserting a light and thin minimum reinforcing material. Therefore, in the joinery, fire prevention performance can be ensured while suppressing an increase in cost and weight of the frame and the shoji using the same.

  FIG. 1 is a longitudinal sectional view of a joinery 10 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the joinery 10 shown in FIG.

  As shown in FIGS. 1 and 2, the joinery 10 includes an opening frame 12 that is fixed to the opening of the building frame, and a pair of left and right shojis 14 and 15 that are slidably disposed in the opening 13 of the opening frame 12. With. In the present embodiment, a sliding window joinery 10 that can open and close the opening 13 inside the opening frame 12 by sliding the shojis 14 and 15 is illustrated. One of the shojis 14 and 15 may be a sliding window in which one of the shojis 14 and 15 is fitted to the opening frame 12 and the other slides. The number of shojis installed can be changed as appropriate.

  The opening frame 12 is a rectangular opening formed by quadrangling an upper frame 12a, a lower frame 12b, and left and right vertical frames 12c and 12d. The opening frame 12 is a frame having a composite structure in which a metal frame member 16 disposed on the outdoor side and a resin frame member 18 disposed on the indoor side are combined. The metal frame 16 is an extruded metal shape such as aluminum. The resin frame 18 is an extruded shape of resin such as vinyl chloride resin (PVC).

  In this application, the prospective direction refers to the indoor / outdoor direction of the joinery 10 (the direction indicated by the arrow Z in the drawing), and the prospective surface refers to a surface extending along the prospective direction. The finding direction is a direction orthogonal to the prospective direction, and in the case of the vertical frames 12c, 12d that are long in the vertical direction, the horizontal direction (direction indicated by an arrow X in the figure) orthogonal to the longitudinal direction is referred to. In the case of the upper frame 12a and the lower frame 12b that are long in the direction, the vertical direction (the direction indicated by the arrow Y in the figure) perpendicular to the longitudinal direction is referred to. The finding surface is a surface along the finding direction. The inner side (inner circumference) of the opening frame 12 refers to a portion on the opening 13 side where the shoji 14 is disposed, and the outer side (outer periphery) of the opening frame 12 refers to a portion on the opposite side to the opening 13 side.

  The upper frame 12 a is obtained by mounting the resin upper frame 18 a of the resin frame member 18 on the metal upper frame 16 a of the metal frame member 16. The lower frame 12 b is obtained by mounting the resin lower frame 18 b of the resin frame member 18 and the resin lower frame cover 18 c on the metal lower frame 16 b of the metal frame member 16. The vertical frames 12c and 12d are obtained by mounting the resin vertical frames 18c and 18d of the resin frame member 18 on the metal vertical frames 16c and 16d of the metal frame member 16, respectively. The opening frame 12 is fixed to the building frame using a fixture 20 such as a nail or a screw.

  As shown in FIG. 1, rails 22 and 23 are formed on the inner prospective surface 21 of the upper frame 12a so as to protrude side by side in the prospective direction. The rail 22 is a guide strip that slidably guides the outdoor shoji 14 serving as an external shoji. The rail 23 is a guide strip that guides the indoor shoji 15 serving as an inner shoji so as to be slidable. The rails 22 and 23 extend over the entire length in the longitudinal direction of the upper frame 12a and protrude inward. A windbreak plate 24 is provided between the rails 22 and 23 and corresponding to the summing portion of the shojis 14 and 15 to maintain the airtightness inside and outside the room. On the inner prospective surface 21, a thermally expandable member 25 is provided at a position that is a side portion in the direction in which the windshield plate 24 is found. The thermally expandable member 25 is a heated foam material such as graphite that expands when heated, for example.

  The metal upper frame 16 a has a hollow portion 26 on the opposite side of the inner prospective surface 21. The hollow portion 26 is provided so as to extend in a prospective direction from the outdoor side end portion of the metal upper frame 16 a to the vicinity of the rail 23. The interior of the hollow portion 26 is divided into two chambers by a column wall 26a provided on the extension line of the outdoor side rail 22. In other words, the strut wall 26a and the rail 22 have the same expected direction position.

  Rails 28 and 29 are formed on the inner prospective surface of the lower frame 12b so as to protrude in the prospective direction. The rail 28 is a guide strip that guides the shoji 14 so as to be slidable. The rail 29 is a guide strip that guides the shoji 15 so as to be slidable. The rails 28 and 29 extend over the entire length in the longitudinal direction of the lower frame 12b and protrude inward. The windshield plate 24 and the thermally expandable member 25 are also provided on the lower frame 12b.

  A hollow portion 30 is provided in the metal lower frame 16b of the lower frame 12b. The hollow portion 30 is provided so as to extend in a prospective direction from the outdoor side end portion of the metal lower frame 16b to the vicinity of the rail 29. A reinforcing material 31 is inserted into the hollow portion 30. For example, the reinforcing material 31 has a length slightly longer than half of the entire length of the hollow portion 30. The reinforcing material 31 is formed by bending a non-flammable or flame retardant metal plate such as stainless steel or steel into a substantially U shape.

The indoor-side protrusion 37 is provided substantially at the center of the outer side plate portion 31b. As shown in FIG. 1, in the case of the present embodiment, the wall portion 41 that forms the outer prospective surface (lower surface) of the hollow portion 30 of the metal lower frame 16 b of the lower frame 12 b is inclined upward toward the indoor side. An inclined surface 41a is provided. For this reason, the reinforcing member 31 may roll counterclockwise in FIG. 1 when inserted into the hollow portion 30 and the workability of the fastening operation of the screw 35 may be reduced. The outer plate 31b has a larger gap between the outdoor end and the wall 41 than the gap between the indoor end and the inclined surface 41a. For this reason, the load from the wall 41 (inclined surface 41a) is concentrated on the indoor side end portion of the outer side plate portion 31b, and the deformation amount near the outdoor side end portion is larger than the deformation amount near the indoor side end portion. Therefore, there is a concern that the reinforcing material 31 may be deformed or the lower frame 12b may be rolled or deformed. Therefore, in the present embodiment, the protrusion 37 is provided on the outer plate portion 31b of the reinforcing member 31 to prevent the occurrence of problems such as deformation of the reinforcing member 31 and the lower frame 12b. The number and position of the protrusions 37 can be changed as appropriate.

A heat-expandable member 25 having a predetermined length is provided on the inner surface on the indoor side of the hollow portion 66. The opening groove 64 is provided with a drop-off prevention fitting 82 having a substantially U-shaped cross section similar to that of the door rod 36c. The drop-off prevention fitting 82 is fastened and fixed to the reinforcing member 68 by a screw 81 that passes through the bottom wall of the opening groove 64. The drop-off prevention metal fitting 82 may have a substantially L-shaped cross section, for example. A thermally expandable member 25 is provided over the entire length of the drop-off prevention fitting 82 at the bottom surface indoor side end of the drop-off prevention fitting 82. A heat-expandable member 25 having a predetermined length is provided on the inner surface on the indoor side of the opening groove 64.

  As for the summoning bowl 36e of the shoji 15, the thermal expansion member 25 covering the entire length is provided on the outdoor-side finding surface. The reinforcing member 76 is fastened and fixed to the metal summoning rod 36e with screws 81. The thermally expandable member 25 is provided on the inner surface on the indoor side of the hollow portion 72 on the outdoor side at a position that becomes the side portion of the reinforcing member 76, that is, a position that becomes the end portion of the summoning rod 36 e. A heat-expandable member 25 having a predetermined length is provided on the inner surface on the indoor side of the hollow portion 72, that is, on the wall portion 77 that partitions the hollow portions 72 and 73.

  As shown in FIGS. 3 (A) to 4 (B), the hollow portions 66 and 72 of the summoning rods 36d and 36e are provided with reinforcing members 68 and 76, but the other ribs 36a, 36b and 36c No reinforcing material is inserted into the hollow portions 48, 54, 62. That is, in the joinery 10, the reinforcing members are inserted in order to secure sufficient strength against fire resistance and wind pressure strength, etc. for the summon bars 36 d and 36 e that are not supported by the opening frame 12. On the other hand, with respect to the other flanges 36a, 36b, and 36c supported by the opening frame 12, a sufficient fireproof strength is secured by making a part of the wall portions thick.

  Specifically, in the upper collar 36a, the outdoor wall 84 of the metal upper collar 40a that forms at least the outdoor-side finding surface 84a of the hollow section 48 has a thick structure (see FIG. 3A). In the upper flange 36a, the bottom wall portion 85 that forms the estimated bottom surface of the opening groove 46 and the bottom wall portion 86 that forms the estimated bottom surface of the guide groove 44 also have a thick structure. In this embodiment, the plate | board thickness of the outdoor side wall part 84 and the bottom wall parts 85 and 86 is set equally, and it is each plate | board thickness t1. That is, the three wall portions 84 to 86 forming the hollow portion 48 have a thick plate thickness t1.

  As for the lower collar 36b, the outdoor side wall part 88 of the metal lower collar 40b which forms the outdoor side finding surface 88a has a thick structure (refer FIG. 3 (B)). In the lower rod 36b, the bottom wall portion 89 that forms the bottom expected surface of the opening groove 52 may also have a thick structure. However, in this embodiment, since the bottom wall portion 89 is provided with a screw hole, the bottom wall portion 89 does not have a thick structure. The outdoor side wall portion 88 has the same thickness t1 as the outdoor side wall portion 84 of the upper collar 36a. In the present embodiment, the indoor side wall 90 of the metal lower collar 40b has a thick structure with a plate thickness t1. That is, the two wall portions 88 and 90 forming the hollow portion 54 have a thick plate thickness t1.

  In the door-end fence 36c, at least the outdoor-side wall portion 92 of the metal door-end fence 40c forming the outdoor-side finding surface 92a has a thick structure (see FIG. 4A). Note that, in the door-end fence 36 c, the bottom wall portion 93 that forms the prospective bottom surface of the opening groove 60 has a thick structure. In this embodiment, the plate | board thickness of the outdoor side wall part 92 and the bottom wall part 93 is set equally, and it is the same plate | board thickness t1 as the outdoor side wall part 84 of the upper collar 36a, respectively. That is, the two wall portions 92 and 93 forming the hollow portion 62 have a thick plate thickness t1.

  The summing rod 36d of the shoji 14 has a reinforcing member 68 inserted into the hollow portion 66 in order to ensure its fireproof strength and wind pressure strength. Therefore, each wall portion forming the hollow portion 66 has a thickness t2 that is thinner than the thickness t1 (see FIG. 4B). In other words, since the reinforcing material 68 is inserted into the summoning bowl 36d, it is not necessary to form the metal summoning bowl 40d thick. Specifically, in the summon bowl 36d, the wall portion 71 that forms the outdoor-side finding surface 71a of the hollow portion 66 has a thin wall thickness t2. Further, the summoning bowl 36d includes a wall portion 75 that forms an inner prospective surface on the opening groove 64 side of the hollow portion 66, a wall portion 79 that forms an outer prospective surface of the hollow portion 66, and a wall portion that forms an indoor-side finding surface. The thickness of 87 is also a thin plate thickness t2. However, in this embodiment, a part of the wall portion 87 that forms the pocket-shaped concave portion in which the tight material is provided is thicker than the plate thickness t2.

  As for the summoning box 36e of the shoji 15, the reinforcing material 76 is inserted into the hollow part 72 on the outdoor side in order to secure the fireproof strength and the wind pressure strength (see FIG. 4B). Therefore, each wall portion forming the hollow portion 72 has a thickness t2 that is thinner than the thickness t1. In other words, since the reinforcing member 76 is inserted into the summoning bowl 36e, it is not necessary to form the metal summoning bowl 40e thick. Specifically, the summoning bowl 36e includes a wall portion 91 that forms an inner prospective surface on the opening groove 70 side of the hollow portion 72, a wall portion 96 that forms an outer prospective surface of the hollow portion 72, and the wall portion 77. The thickness is a thin plate thickness t2. However, in the present embodiment, a part of the outdoor side wall portion 94 that forms the pocket-shaped concave portion in which the thermally expandable member 25 is provided is thicker than the plate thickness t2.

  On the other hand, in the hollow portion 73 on the indoor side where the reinforcing material is not inserted, the indoor side wall portion 95 that forms the indoor-side finding surface 95a of the metal summoning bowl 40e has a thick plate thickness t3. The other three wall portions of the hollow portion 73 have a thin plate thickness t2. The hollow portion 73 on the indoor side has a reinforcing structure 76 inserted into the hollow portion 72 on the outdoor side, and is not directly related to the holding of the face material 38, and thus can be configured with a thin structure. However, in order to improve the fire prevention performance in the hollow portion 72 when the joinery 10 receives a flame or heat from the indoor side, the indoor side wall portion 95 has a thick plate thickness t3.

  In this case, in the joinery 10 according to the present embodiment, the metal summing rod 40d (40e) of the summoning rod 36d (36e) has a hollow portion (first hollow portion) in which the reinforcing material 68 (76) is inserted. ) 66 (72) is provided, and at least the plate thickness t1 of the outdoor side wall portion 92 forming the outdoor side finding surface 92a is hollow in the metal side door rod 40c of the door side rod 36c. A hollow portion (second hollow portion) 62 that is thicker than the plate thickness t2 of the wall portions 71, 75, 79, 87 (77, 91, 96) forming the portion 66 (72) is provided.

  That is, for holding the face material 38 when the joinery 10 receives a flame or heat, the fireproof strength of the door toe 36c and the summon 36d (36e), which are vertical fences, is important. In this regard, the joinery 10 has the reinforcing material 68 (76) inserted in the hollow portion 66 (72) of the summoning bowl 36d (36e). Thereby, the joinery 10 can ensure the fireproof strength at the summoning tub 36d (36e) which is not supported by the opening frame 12. Further, the joinery 10 has a wall portion forming the hollow portion 66 (72) of the summit rod 36d (36e) with respect to the plate thickness t1 of the outdoor wall portion 92 of at least the wall portion forming the hollow portion 62 of the door rod 36c. Is set to be thicker than the plate thickness t2. That is, the door toe 36c has a thick structure. As a result, the door toe 36c can ensure sufficient fireproof strength without inserting a reinforcing material into the hollow portion 62 or by inserting a light and thin minimum reinforcing material. Therefore, in the joinery 10, it is possible to ensure fire prevention performance while suppressing an increase in cost and weight of the frame 36 (the shoji 14, 15). Furthermore, since the door-end fence 36c has a thick structure, the number of the thermally expandable members 25 installed on the door-end fence 36c can be reduced, and the cost can be further reduced.

  The wall portions 71, 75, 79, and 87 of the hollow portion 66 can be reduced in weight and cost if one or more of the wall portions are formed with a thin plate thickness t2. The same applies to the wall portions 77, 91, and 96 of the portion 72. Further, for example, there is a portion that is partially thick, such as the wall portion 87, but even if there is a thick portion in part, the majority of the wall portion 87 may be configured to be thin. In this case, the increase in weight and cost is limited, and a sufficient effect may be obtained.

  In the joinery 10, the hollow portion 62 of the door toe 36 c has a thickness t 1 of the bottom wall portion 93 that forms the opening side wall portion that forms the opening groove 60 that holds the face material 38, and the hollow of the summing rod 36 d (36 e). It is thicker than the plate thickness t2 of the wall portions 71, 75, 79, 87 (77, 91, 96) forming the portion 66 (72). Thereby, the joinery 10 can further raise the fireproof strength with respect to holding | maintenance of the face material 38 in the door-end fence 36c.

  As described above, in the joinery 10, the door-end fence 36 c has a thick structure, so that sufficient fireproof strength can be secured in the hollow portion 62 without inserting a reinforcing material. For this reason, the joinery 10 can be significantly reduced in cost and weight.

  In the joinery 10, at least the plate thickness t1 of the outdoor side wall portion 84 forming the outdoor side finding surface 84a forms the hollow portion 66 (72) of the summoning side plate 36d (36e) on the metal upper side rod 40a of the upper side rod 36a. A hollow portion (third hollow portion) 48 that is thicker than the plate thickness t2 of the wall portions 71, 75, 79, 87 (77, 91, 96) is provided. Further, in the metal lower bar 40b of the lower bar 36b, at least the plate thickness t1 of the outdoor side wall part 88 that forms the outdoor side finding surface 88a is a wall that forms the hollow part 66 (72) of the summing bar 36d (36e). A hollow portion (fourth hollow portion) 54 that is thicker than the plate thickness t2 of the portions 71, 75, 79, 87 (77, 91, 96) is provided. Thus, the joinery 10 also has a thick-wall structure also about the upper collar 36a and the lower collar 36b. As a result, the upper rod 36a and the lower rod 36b can ensure a sufficient fireproof strength without inserting a reinforcing material into the hollow portions 48 and 54 or by inserting a light and thin minimum reinforcing material. Therefore, in the joinery 10, fire prevention performance can be ensured while further suppressing an increase in cost and weight of the frame 36 (the shojis 14 and 15). Furthermore, by making the upper collar 36a and the lower collar 36b have a thick structure, the number of the thermally expandable members 25 installed on the upper collar 36a and the lower collar 36b can be reduced, and the cost can be further reduced. Such a thick-walled structure does not necessarily have to be provided on all of the upper and lower rods 36a, 36b and 36c. If one or more of the rods 36a to 36c are provided according to the fireproof specifications, etc. Good.

  In the joinery 10, the metal summoning rod 40 e of the summoning rod 36 e is provided with a hollow portion (fifth hollow portion) 73 aligned with the indoor side of the outdoor hollow portion (first hollow portion) 72. And while one wall part of the hollow part 72 forms the opening groove | channel 70 which hold | maintains the face material 38, the reinforcing material is not inserted in the hollow part 73. FIG. That is, in the shoji 15 which is an inner shoji of the fitting 10, the outdoor hollow portion 72 forms the opening groove 70 for holding the face material 38, and thus requires a sufficient fireproof strength. Moreover, since this hollow part 72 also becomes a summoning part with the shoji 14 used as an external shoji, the intensity | strength with respect to a wind-resistant pressure etc. is also required. On the other hand, the hollow part 73 on the indoor side has little influence on the fireproof strength and the like. Therefore, in the joinery 10, the reinforcing material 76 is inserted into the hollow portion 72 on the outdoor side, while the reinforcing material is not inserted into the hollow portion 73 on the indoor side, so that a balance between strength, cost, and weight is achieved.

  In the joinery 10, the upper frame 12 a of the opening frame 12 has a hollow portion 26 on the opposite side of the inner prospective surface 21 on the side of the shoji 14, 15. That is, the hollow part 26 forms the heat insulation structure part of the upper frame 12a. Thereby, the joinery 10 can relieve the influence of a flame, heat, or solar radiation with the hollow part 26, and can suppress producing the damage to the inner prospective surface 21 side of the upper frame 12a which supports the shojis 14 and 15. Further, it is possible to prevent the upper frame 12a from opening in the event of a fire and dropping the shojis 14 and 15.

  In this case, the upper frame 12 a has a rail 22 for projecting the shoji 14 projected from the inner prospective surface 21, and the inside of the hollow portion 26 is partitioned by a column wall 26 a provided on an extension line of the rail 22. ing. Thus, since the upper frame 12a has the support | pillar wall 26a on the extension line | wire of the rail 22, the thermal expansion of the shoji 14 at the time of a fire etc. can be suppressed by the support | pillar wall 26a. As a result, a gap is hardly generated between the upper frame 12a and the outdoor shoji 14 and the fireproof strength is further improved.

  In the summoning bowl 36e, a U-shaped reinforcing member 76 inserted into the hollow part 72 on the outdoor side is arranged in such a direction as to open to the wall part 77 side separating the hollow part 73 from the indoor side. Thereby, when receiving a flame or heat from the outdoor side, this can be reliably prevented at the bottom of the reinforcing member 76.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  In the above embodiment, the sliding window configured to be able to slide the two shojis 14 and 15 is illustrated. However, the joinery 10 may be configured by a single sliding window in which one shoji 15 is fitted to the opening frame 12 and killed. Good. Moreover, the fitting 10 may be comprised with the sliding door which provided the sliding paper of 3 or more sheets so that a slide was possible. In this case, the shoji used as the middle of the shoji of the right-and-left both ends side becomes a structure which does not have a door-end fence.

  In the above embodiment, the composite sash having the opening frame 12 and the housing 36 made of a composite structure of aluminum and resin is exemplified. However, the fitting 10 may be applied to an aluminum sash having the opening frame 12 and the housing 36 made of aluminum alone. Applicable.
