The joinery 1 according to the embodiment described above has the following effects.
The joinery 1 is disposed so as to close the gap between the frame 30, the door 10 provided to be opened and closed inside the frame 30, and the door 10 and the frame 30 in the closed position. Upper airtight material 41, suspension side airtight material 43 and door-end side airtight material 44, and upper heating foam material 61 disposed in the vicinity of upper airtight material 41, suspension-side airtight material 43 and door-end side airtight material 44, respectively. The suspension base side heating foam material 63 and the door end side heating foam material 64 are provided.

  Thereby, since an airtight material burns down at the time of a fire, the situation where foaming of a heating foaming material is inhibited can be avoided. In addition, it is not necessary to use airtight materials separately for fireproof specifications and non-fireproof specifications, so parts can be shared and productivity is improved.

  Moreover, in this embodiment, the upper side airtight material 41, the suspension origin side airtight material 43, and the door-end side airtight material 44 are the upper heating foam material 61, the suspension origin side heating foam material 63, and the door-end side heating foam material 64, respectively. Arranged to cover.

  Thereby, it becomes difficult to see a heating foam material on an external appearance, and designability can be improved. In addition, in both cases of fireproof specifications and non-fireproof specifications, the heat-foamed material becomes invisible, so that the appearance can be matched and common design can be realized.

  Moreover, in this embodiment, the upper side heating foam material 61, the suspension side heating foam material 63, and the door-end side heating foam material 64 are arrange | positioned at the prospective surface of the frame 30, and the upper side airtight material 41, the suspension side airtight material 43 and the door-end side airtight material 44 are arranged on the main body portions 411, 431, and 441 arranged so as to face the heating foam material in the finding direction, and from the main body portions 411, 431, and 441 to the expected surface of the frame body 30. And cover portions 414, 434, and 444 formed so as to cover the upper heating foam material 61, the suspension base heating foam material 63, and the door end side heating foam material 64, respectively.

  Thereby, since the heating foam is directly fixed to the frame, it is not necessary to prepare a separate space for arranging the heating foam, and the structure of the frame can be shared between the case of the fireproof specification and the case of the fire prevention specification. Therefore, productivity can be further improved. Further, by using the cover portion, it is possible to dispose the heating foam material without changing the position of the airtight material, and the degree of freedom in layout is improved. This makes it possible to arrange the heating foam close to the door side while making the heating foam invisible from the outside. Furthermore, since the gap between the frame and the frame becomes difficult to see, the design can be improved both in the case of the fireproof specification and not.

  Further, in the present embodiment, the frame 30 has an upper mounting portion 51 that extends in the direction of attachment and attaches the upper airtight member 41, the hanging side airtight member 43, and the door end side airtight member 44, and the hanging side mounting portion. 53 and the door end side attaching portion 54 are provided, and the upper side attaching portion 51, the hanging side side attaching portion 53 and the door end side attaching portion 54 are provided with an upper side heating foam material 61, a hanging side side heating foam material 63 and a door side side heating. The main body portions 411, 431, and 441 are fixed so that a gap is generated between the foam material 64 and the foam material 64, respectively.

  As a result, a gap is formed between the hermetic material and the heated foam material, so that when the hermetic material is inserted into the mounting portion, the hermetic material and the heated foam material can be prevented from being in contact with each other, which can prevent insertion. . Moreover, even if a part of the heating foam material is peeled off from the frame body, it is received by the main body portion, so that the heating foam material does not fall off completely.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not restrict | limited to the above-mentioned embodiment, It can change suitably.

  In the said embodiment, although the upper side airtight material 41, the suspension origin side airtight material 43, and the door-end side airtight material 44 are the structures which have the cover parts 414,434,444, respectively, the shape of an airtight material is the structure of the said embodiment. It is not limited. For example, the cover portions 414, 434, and 444 can be omitted. Even if the cover portion is omitted, the heated foamed material is located on the back side of the airtight material, so that the heated foamed material can be hardly seen from the outside. Further, the screw 65 as the fastening member may be omitted to make the gap between the hermetic material and the heating foam material smaller, or in some cases, a part or all of the hermetic material and the heating foam material may be brought into contact with each other. .
