Japanese Patent No. 4850779

  By the way, in the case of the joinery as described above, the upright has a support structure in which upper and lower ends are supported by upper and lower frames. For this reason, the vertical is more easily deformed in the event of a fire than the sliding door frame or the sleeve wall panel frame connected in a frame shape. In particular, since the vertical is not supported in the vicinity of the center in the longitudinal direction, there is a possibility that the vicinity of the center is warped indoors and deforms into an arcuate shape in the event of a fire. When the vertical is deformed, a through-hole in the indoor / outdoor direction is formed between the vertical and the sliding door, and this through-hole may become a passage for flames and smoke.

  The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a joinery that can improve fire prevention performance.

And opening and closing an opening formed by the upper frame, the lower frame, the door-end side vertical frame, and the vertical frame, which is slidably supported along the longitudinal direction with respect to the upper frame and the lower frame. And a sleeve wall panel held in an opening formed by the upper frame, the lower frame, the intermediate vertical frame, and the door bottom side vertical frame, A reinforcing material provided along the longitudinal direction of the reinforcing material and attached to the intermediate vertical frame and locking the reinforcing material to the indoor side of the reinforcing material A locking member for restricting the movement, characterized in that it comprises a.

  According to such a configuration, the movement of the reinforcing material provided in the vertical direction to the indoor side is restricted by the locking member attached to the intermediate vertical frame. Thereby, at the time of the fire of the said fitting, it can suppress by a locking member that the reinforcing material heat-extends, for example, and produces the bow-shaped curvature deformation that a center part moves indoor side. As a result, it is possible to prevent the formation of a through hole in the indoor / outdoor direction between the vertical and the sliding door, and to improve the fireproof performance.

  In the fitting according to the present invention, the locking member is a screw that is screwed into a screw hole formed in the intermediate vertical frame, and the locking member locks the reinforcing material by an outer peripheral surface of the screw. It is good also as a structure. If it does so, the fixing operation | work of the latching member with respect to an intermediate | middle vertical frame will become easy. Since the vertical outdoor side is supported by the sliding door, the reinforcing material tends to move to the indoor side when heated. Therefore, the locking member can restrict warping deformation of the reinforcing material simply by locking the reinforcing material on the outer peripheral surface of the screw. Since the forming operation and the screw hole positioning are not required, the installation operation is further facilitated.

  In the joinery according to the present invention, the reinforcing member includes at least a first plate portion along a prospective direction of the vertical, a second plate portion bent from the first plate portion and along the direction of finding the vertical, The locking member may be configured to be opposed to the indoor-side finding surface of the second plate portion. Then, it is possible to easily achieve both vertical reinforcement by the reinforcing material and restriction of movement of the reinforcing material by the restricting member.

  In the joinery according to the present invention, the intermediate vertical frame is formed with an indoor side frame portion in which an indoor side wall portion of an opening groove that holds a side end portion of the sleeve wall panel is formed, and an outdoor side wall portion of the opening groove. An outdoor frame part, and a heat insulating member that connects the indoor frame part and the outdoor frame part, and the locking member is attached to the outdoor frame part. Good. Then, even if the heat insulating member of the intermediate vertical frame melts or disappears in the event of a fire and the indoor side frame portion and the outdoor side frame portion of the intermediate vertical frame are separated, the regulating member is placed on the indoor side finding surface of the reinforcing material. Since it is locked, the outdoor frame portion is restricted from moving to the outdoor side. For this reason, the holding state of the sleeve wall panel by the outdoor frame is maintained, and the sleeve wall panel is prevented from falling off.

  In the joinery according to the present invention, a resin profile is disposed between the inner prospective surface of the vertical and the outer prospective surface of the intermediate vertical frame facing the inner prospective surface, It is good also as a structure which provided the thermal expansible member which expand | swells when heated so that it may face the space between the said inner surface and the said outer surface where the said resin-made shape material was arrange | positioned. Then, the thermally expandable member that expands in the event of a fire closes the gap between the vertical and intermediate vertical frame formed when the resin profile is burned out, and this gap becomes a through hole in the indoor / outdoor direction. To prevent that.

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

For this reason, the outdoor side collar part 55 is prevented from falling off, and the holding state of the upper end part of the sleeve wall panel 20 by the outdoor side collar part 55 is maintained, so that the sleeve wall panel 20 can be prevented from falling off and the fire prevention performance is improved. can do. The restricting metal fitting 80 can be used for fittings other than sliding doors with sleeves. For example, the restricting metal fitting 80 can be used for a fitting window in which a panel body is fitted in an opening frame (housing) fixed to a building frame.

  In the joinery 10, the locking member 92 that restricts the movement of the reinforcing member 90 provided on the vertical wall 44 to the indoor side is firmly assembled with the upper eaves 18 a, the lower eaves 18 b, and the door bottom side vertical frame 12 d. It is attached to the intermediate vertical frame 46. For this reason, it can suppress by the latching member 92 that the reinforcing material 90 heat-extends at the time of a fire, and produces the bow-shaped curvature deformation | transformation which a center part moves indoor side. As a result, it is possible to prevent the formation of a through hole in the indoor / outdoor direction between the vertical 44 and the sliding door 16. Therefore, it is desirable that the locking member 92 is provided at least in the central portion or the vicinity thereof in the longitudinal direction (vertical direction) of the reinforcing member 90. In the present embodiment, the locking member 92 is installed, for example, near the upper end, near the center, and near the lower end. Since the sliding door 16 is provided on the outdoor side of the vertical wall 44, the reinforcing member 90 hardly deforms in a bow shape in the direction opposite to the above-described direction. What is necessary is just to be able to regulate the movement to the indoor side. The locking member 92 may be composed of, for example, a metal rod or a metal piece other than a screw.

  In the case of this embodiment, the locking member 92 is fixed to the outdoor side frame portion 49 of the intermediate vertical frame 46. Therefore, even when the heat insulating member 50 of the intermediate vertical frame 46 melts or disappears during a fire, and the indoor side frame portion 48 and the outdoor side frame portion 49 of the intermediate vertical frame 46 are separated, the locking member 92 is Since the reinforcing member 90 is locked to the indoor-side finding surface 90d, the outdoor frame portion 49 is restricted from moving to the outdoor side. Therefore, the outdoor side frame portion 49 is prevented from falling off, the holding state of the side end portion of the sleeve wall panel 20 by the outdoor side frame portion 49 is maintained, and the sleeve wall panel 20 is more reliably prevented from falling off.

  The joinery 10 is provided with drop-off prevention fittings 84, 95, and 96 in the opening grooves 52, 66, and 68 of the upper collar 18a, the intermediate vertical frame 46, and the door-side vertical frame 12d that hold the sleeve wall panel 20, respectively. Provided. For this reason, the joinery 10 is heated for a long time, for example, in the event of a fire, and the upper flange 18a, the intermediate vertical frame 46, and the outdoor flange 55 and the outdoor frame 49, 39 of the door-side vertical frame 12d are softened or melted. In this case, the upper end portion and the side end portion of the sleeve wall panel 20 can be held even when the heat insulating members 56, 50, 40 are melted or disappeared, and the sleeve wall panel 20 can be more reliably detached. Can be prevented. At this time, the bridge portion 84d of the drop-off prevention metal fitting 84 extends so as to straddle the heat insulating member 56 at a position separated from the heat insulating member 56, and connects the fixing portion 84a and the holding portion 84c. For this reason, it is suppressed that the drop-off prevention metal fitting 84 normally becomes a thermal bridge between the indoor side flange portion 54 and the outdoor side flange portion 55 and deteriorates the heat insulation performance of the joinery 10. 96 have a similar heat insulating structure. Since the upper collar 18a is an important part for preventing the sleeve wall panel 20 from falling off, the stopper metal fitting 84 also has a holding portion 84b for holding the indoor side surface 20c of the sleeve wall panel 20. Yes. However, in the case of the present embodiment, since the building housing 21 and the frame member fixed thereto are arranged on the indoor side of the holding portion 84b and the indoor side flange portion 54 on the indoor side, the holding portion 84b is provided. Even if omitted, sufficient fireproof performance can be secured. Further, if the upper collar 18a is provided with the drop-off prevention metal fitting 84, the other drop-off prevention metal fittings 95, 96 may be omitted, and conversely, only the drop-off prevention metal fitting 95, 96 is provided and the drop-off prevention metal fitting 84 is omitted. May be. The drop-off prevention metal fittings 84, 95, and 96 can be used for fittings other than the sliding doors with sleeves. It can also be used for a shoji frame that can be opened and closed.

  In the joinery 10, the drop-off prevention fittings 84, 95, and 96 have thermal expansion members 86 at positions facing the end faces 20 e, 20 g, and 20 h of the glass plate 20 b that is fireproof glass. For this reason, when the thermally expandable member 86 expands in the event of a fire, the gaps between the drop-off prevention metal fittings 84, 95, 96 and the end surfaces 20e, 20g, 20h of the glass plate 20b are closed, and the gaps are indoors and outdoors. It can prevent becoming a through hole in the direction. In the present embodiment, the reinforcing member 76 provided in the opening groove 58 of the lower rod 18b is also provided with a thermally expandable member 88 at a position facing the lower end surface 20f of the glass plate 20b. For this reason, since the clearance gap between the outer peripheral end surface of the glass plate 20b and the housing 18 is block | covered with the thermally expansible members 86 and 88 over four circumferences at the time of fire, the joiner 10 can obtain still higher fire prevention performance.

  Further, the drop-off prevention fittings 84, 95, 96 have a thermally expandable member 87 at a position facing the outdoor side surface 20d of the glass plate 20b. Thereby, at the time of the fire of the joinery 10, the gap between the outdoor surface 20 d of the sleeve wall panel 20 and the drop-off preventing metal fittings 84, 95, 96 is closed by the expanded thermal expansion member 87. For this reason, the gap is prevented from being a through hole communicating in the indoor / outdoor direction, and the sleeve wall panel 20 is held by the expanded thermal expansible member 87, and the fall off is more reliably prevented.

  In the case of this embodiment, since the glass plate 20b on the outdoor side of the sleeve wall panel 20 is made of fireproof glass, the configuration in which the thermally expandable members 86 and 87 are provided around the glass plate 20b is exemplified. When the glass plate 20a is made of refractory glass, the thermally expandable members 86 and 87 are preferably provided on this side. The same applies to the drop-off prevention metal fittings 84, 95, and 96. When the indoor side glass plate 20a is made of fireproof glass, the fixing portion 84a is fixed to the outdoor side flange portion 55 and the outdoor side frame portions 49 and 39, and the bridge. The portion 84d may be extended to the indoor side flange portion 54 and the indoor side frame portions 48 and 38, and the holding portion 84c may be disposed to face the indoor side surface 20c.

  In the joinery 10, the heat-expandable members 93 and 94 are also provided in the vertical portion 14. The heat-expandable member 93 closes the gap between the vertical wall 44 and the intermediate vertical frame 46 formed when the bridge member 47 made of resin such as PVC is burned out in the event of the fire of the joinery 10, and this gap is indoors. Prevents the formation of an outward through hole. Further, the thermally expandable member 94 closes a gap between the indoor smoke return piece 44b and the outdoor smoke return piece 16h of the sliding door 16 in the event of a fire of the joinery 10, and this gap becomes a through hole in the indoor / outdoor direction. To prevent that.

  Next, the fire prevention structure in parts other than the peripheral part of the sleeve wall panel 20 is demonstrated. In the case of this embodiment, the joinery 10 also has a fire prevention structure in the sliding door 16 and its peripheral part. As shown in FIG. 3, thermal expansion members 97a and 97b are provided between the outer surface of the aggregate 16c and the inner surfaces of the surface materials 16a and 16b on the left and right sides of the sliding door 16, and heat is applied to the inner surface of the aggregate 16c. Inflatable members 97c and 97d are provided, and thermally expandable members 97e, 97f, 97g, 97h, 97i, and 97j are provided on the cover members 16e and 16f. As shown in FIG. 2, thermally expandable members 98 a, 98 b, 98 c, 98 d, and 98 e are provided at the upper and lower portions of the sliding door 16. The heat-expandable members 98b and 98d are provided on an outdoor-side finding surface of a portion provided between the door frame side vertical frame 12c and the vertical portion 14 of the upper frame 12a and the lower frame 12b, for example. The thermally expandable members 98c and 98e are provided at the upper and lower ends of the sliding door 16, for example.

  The thermally expandable members 97a to 97j and 98a to 98e are provided over the longitudinal direction of the aggregate 16c of the sliding door 16, for example. Thereby, at the time of the fire of the joinery 10, the heat-expandable members 97a to 97j prevent the occurrence of through-holes in the indoor / outdoor direction between the sliding door 16 and the door-end side vertical frame 12c or between the sliding door 16 and the vertical portion 14. And the thermally expansible members 98a-98e prevent generation | occurrence | production of the through-hole of the indoor / outdoor direction between the sliding door 16, and the upper frame 12a and the lower frame 12b.
