JP2013-127167A

By the way, in the door of patent document 1, since the operation | work which attaches a nonflammable tight material to the tight material holder of each frame, and the operation | work which attaches a thermal expansion refractory material to the prospective surface of each fence, these attachments are required. Work takes time and it is difficult to improve workability.
Moreover, in order to ensure airtightness between the frame and the door, and to prevent the spread of fire from the gap between the frame and the door, both a nonflammable tight material and a thermal expansion refractory material are required. Therefore, it is difficult to reduce the number of parts.

  An object of the present invention is to provide a joinery that can exhibit airtight performance and fireproof performance and can improve workability by reducing the number of parts.

  The joinery of the present invention includes a frame body having a finding piece portion and a prospective piece portion, a shoji that is supported by the frame body so as to be openable and closable, and whose indoor surface is positioned facing the finding piece portion in a closed state. And an airtight material that closes a gap between the sliding piece and the indoor surface of the shoji, and the airtight material is disposed along the finding piece and an engaging portion that engages with the finding piece. A base piece and an abutment piece portion that abuts against the inner surface of the shoji screen when the shoji is closed, the abutment piece portion is formed of an elastically deformable resin material, and the base portion is a heating foam material It is formed by the foamed resin material formed including, and is spaced apart in the direction of finding from the prospective piece portion of the frame.

According to the joinery of the present invention, since the airtight member has the abutting piece portion formed of the elastically deformable resin material that abuts the indoor surface of the shoji, the abutting piece portion is in the shoji room in the closed state of the shoji. Airtight performance can be achieved by elastically deforming in contact with the surface. Furthermore, since the hermetic material has a base portion formed of a foamed resin material, fireproof performance is exhibited by closing the gap between the frame body and the shoji by foaming of the base portion based on heat during a fire or the like, and the fire spread from the gap Can be prevented. Further, since the base portion is disposed along the finding piece portion, the expected size of the airtight material can be appropriately and easily set in consideration of the watertight performance and the fireproof performance. Thereby, the effort which attaches a heating foam material (thermally expansible refractory material) separately can be eliminated, a number of parts can be reduced, and workability can be improved. In addition, since the base of the airtight material is spaced away from the prospective piece of the frame in the direction of finding, a sufficient space can be secured for attaching the airtight material to the founding piece of the frame, Installation of the material becomes easy.
Furthermore, since the base portion is arranged along the finding piece portion, the inflatable direction of the base portion can be set toward the shoji side in the expected direction of the joinery. Thus, for example, even when the shoji is warped due to heat at the time of fire or the like, and the gap between the finding piece of the frame and the indoor surface of the shoji is widened, the base expands in the expected direction toward the shoji. Thereby, the clearance gap between the finding piece part of a frame and the indoor surface of a shoji can be closed. For this reason, it is not necessary to add a heating foam material in addition to the airtight material having the base described above, and the amount of the heating foam material used can be reduced.

In the joinery of the present invention, the finding piece portion has an engaging piece that engages with the engaging portion, and the base portion extends to the prospective surface side of the frame body with respect to the engaging piece. Is preferred.
According to such a configuration, since the base portion extends to the prospective surface side from the engagement piece of the finding piece portion, the prospective direction with respect to the gap between the frame body and the prospective surface of the shoji in the closed state of the shoji The base region opposite to can be increased. Thereby, the clearance gap between the frame and the prospective surface of a shoji can be more reliably closed by the base part which expand | swells with the heat | fever at the time of a fire etc.

In the joinery of the present invention, it is preferable that the base is formed flat and extends in the direction of finding toward the frame body rather than the contact piece in the closed state of the shoji.
According to such a configuration, since the base portion extends in the direction of finding toward the frame body rather than the contact piece portion in the closed state of the shoji, the contact piece portion of the base portion that expands due to heat at the time of a fire or the like The region that expands in the prospective direction without hitting can be expanded, and the space between the prospective surfaces of the frame and the shoji can be more smoothly closed.

In the joinery of the present invention, when the base is formed flat, the thickness dimension of the base is T, and the expected width dimension of the gap between the finding piece part and the shoji is W, the thickness dimension T is , W / 8 or more and W / 2 or less are preferable.
According to such a configuration, when the thickness dimension T of the base portion is set to a size of W / 8 or more, a sufficient amount of the base portion can be secured to close the gap between the frame body and the shoji. Therefore, for example, even when the shoji is warped due to heat at the time of fire or the like, and the gap between the frame finding piece and the indoor surface of the shoji is widened, the gap can be blocked by the expansion of the base. In addition, the gap between the frame and the prospective surface of the shoji can also be closed.
In addition, since the thickness T of the base is set to W / 2 or less, the contact piece is placed in the gap between the finding piece of the frame and the indoor surface of the shoji, and the shoji Space for elastic deformation by being pushed by the indoor surface can be secured.

In the joinery of the present invention, the frame body includes an indoor metal frame member in which the finding piece portion is formed, an outdoor metal frame member disposed on the outdoor side of the indoor metal frame member, and the indoor metal. Preferably, the base portion extends toward the indoor-side metal frame material or the heat insulating material. The heat insulating material is interposed between the frame material and the outdoor metal frame material.
According to such a configuration, most of the outdoor part of the finding piece of the indoor side metal frame member or the whole is located so as to be covered with the base, so that the indoor metal frame material directly touches the outside air from the outdoor side. The heat insulation performance can be improved.
In addition, the expansion of the base portion in the event of a fire etc. closes the gap between the frame and the shoji, and the heat insulating material can be covered by the expansion of the extending portion of the base portion with respect to the indoor metal frame material or the heat insulating material. Insulation line can be maintained.

By setting the above-mentioned gap to 0.5 mm or more, even if there is a slight manufacturing error in the width of the base 52, the base 52 does not excessively interfere with the prospective surface of the vertical frame 23. It is preferably attached. Further, by setting the above-described gap to 2 mm or less, the gap between the door 3 and the vertical frame 23 is smoothly closed by the expansion of the base 52 without the gap being excessively large.

[Operation of this embodiment]
Hereinafter, the operation of the door 1 according to the present embodiment will be described.
When the airtight member 5 is heated during a fire at the outdoor side, the base 52 made of a foamed resin material foams and expands mainly in the expected direction toward the outdoor side. As shown in FIG. 5, the expanding base 52 enters the gap between the prospective surface of the door 3 on the door tip side and the prospective surface of the vertical frame 23 on the door tip side, and closes the gap. To prevent the spread of fire between indoors and outdoors.
Further, the left side portion of the base portion 52 shown in FIG. 5 abuts against the indoor surface of the door 3 by expansion, and closes the gap between the indoor surface of the door 3 and the finding piece portion 252. In this way, in addition to closing the gap between the prospective surfaces of the door 3 and the vertical frame 23, the gap between the indoor surface of the door 3 and the finding piece portion 252 is also closed, so that the spread of fire between the inside and outside of the door 3 is more reliably performed. To prevent.
Furthermore, the base 52 which expand | swells also maintains the heat insulation line between indoors and outdoors by covering the prospective surface of the heat insulating material 26 which adjoins the edge part 522. FIG.

Further, as shown in FIG. 6, when the door 3 is warped due to heat at the time of a fire at the indoor side and the door 3 is separated from the airtight material 5, the base 52 has a thickness dimension T of W / 8 or more. It is formed by a sufficient amount of foamed resin material, and the base 52 formed in this way expands in the prospective direction toward the outdoor side, so that a gap between the indoor surface of the door 3 and the finding piece portion 252 is formed. In addition, the gap between the prospective surfaces of the door 3 and the vertical frame 23 is also closed. The prospective surface of the heat insulating material 26 is also covered.
Such foam expansion of the base 52 of the airtight material 5 at the time of a fire on the outdoor side occurs around the entire circumference of the frame 2 to which the airtight material 5 is attached.

[Effect of this embodiment]
(1) Since the airtight member 5 has the contact piece portion 53 formed of an elastically deformable soft resin material that contacts the indoor surface of the door 3, the contact piece portion 53 is the door 3 in the closed state of the door 3. Airtight performance can be exhibited by elastically deforming by abutting against the interior surface of the door. Furthermore, since the airtight material 5 has a base portion 52 formed of a foamed resin material, fire resistance is achieved by closing the gap between the door 3 and the vertical frame 23 on the door-end side by foaming of the base portion 52 based on heat during a fire or the like. And the spread of fire from the gap can be prevented. As a result, for example, as disclosed in Patent Document 1, separately from the non-combustible tight material, there is no need to attach the thermally expanded refractory material (heated foam material) to the prospective surface of the bag, and the workability is improved by reducing the number of parts. Can be planned. Further, since the base 52 of the airtight material 5 is separated from the prospective pieces 243 and 255 of the frame 2 in the direction of finding, there is sufficient space to attach the airtight material 5 to the found piece 252 of the frame 2. The airtight material 5 can be easily attached to the finding piece 252.
Furthermore, since the base part 52 is arrange | positioned along the finding piece part 252 of the vertical frame 23 by the side of a door, the expansion | swellable direction of the base part 52 can be set to the door 3 side in the prospective direction of the door 1. FIG. Thereby, for example, even when the door 3 is warped due to heat at the time of fire or the like, and the gap between the indoor surface of the door 3 and the finding piece 252 is widened, the base 52 is directed toward the door 3 in the expected direction. By expanding, the gap between the indoor surface of the door 3 and the found piece 252 can be closed. For this reason, in addition to the airtight material 5 having the base 52 described above, it is not necessary to add a heating foam material on the door end side, and the amount of the heating foam material used can be reduced.
(2) Since the base 52 extends to the prospective surface side from the engagement piece 252B, the prospective direction with respect to the gap between the prospective surfaces of the door 3 and the vertical frame 23 on the door-end side when the door 3 is closed. The base region opposite to can be increased. Thereby, the clearance gap between the prospective surfaces of the door 3 and the vertical frame 23 on the door-end side can be more reliably closed by the base portion 52 that is expanded by heat during a fire or the like.
(3) Since the base 52 extends in the direction of finding toward the vertical frame 23 closer to the door tip than the contact piece 53 in the closed state of the door 3, the base 52 expands due to heat during a fire or the like. The region that expands in the prospective direction without hitting the contact piece 53 can be expanded, and the gap between the prospective surfaces of the door 3 and the vertical frame 23 on the door-end side can be more smoothly closed.
(4) Since the base portion 52 is flat, the expected dimension of the airtight member 5 can be set easily and appropriately in consideration of the watertight performance and the fireproof performance. By setting the thickness dimension T of the base 52 to be W / 8 or more, it is possible to secure a sufficient amount of the base 52 to close the gap between the door 3 and the vertical frame 23 on the door-end side. Therefore, for example, even when the door 3 is warped due to heat at the time of a fire or the like and the gap between the finding piece portion 252 of the vertical frame 23 on the door end side and the indoor surface of the door 3 is widened, In addition to closing the gap, the gap between the prospective surfaces of the door 3 and the vertical frame 23 on the door-end side can also be closed.
Further, since the thickness dimension T of the base portion 52 is set to W / 2 or less, the contact piece portion 53 is formed in the gap between the indoor surface of the door 3 and the finding piece portion 252 of the vertical frame 23 on the door-end side. However, when the door 3 is closed, a space for being elastically deformed by being pushed by the indoor surface of the door 3 can be secured.
(5) Since most of the outdoor portion of the finding piece portion 252 of the indoor frame member 25 is covered with the base portion 52, the portion of the indoor frame member 25 that directly contacts the outside air from the outdoor side can be reduced, and heat insulation is performed. The performance can be improved.
Further, the expansion of the base 52 at the time of a fire or the like closes the gap between the door 3 and the vertical frame 23 on the door-end side, and the thermal insulation 26 can be covered by the expansion of the extended portion of the base 52 with respect to the thermal insulation 26, The heat insulation line by the heat insulating material 26 can be maintained.
