A member 62 is formed.
And the indoor side wall of the starboard door frame 24 is made of a synthetic resin and includes an indoor side wall member 62 having a plurality of hollow portions, thereby suppressing the transmission of cold heat from the door pocket 6 to the indoor side. And heat insulation is improved.

On the other hand, the exterior wall of the door pocket 6 has an outdoor starboard door frame 243 made of a metal material such as an aluminum alloy and an outdoor wall member 64 made of a resin material. Is covered by the outdoor wall reinforcing member 63.
The outdoor wall reinforcing member 63 is fixed to the starboard door frame 24 by a plurality of mounting brackets 61 having a substantially L-shaped cross section. As shown in FIG. 8, the mounting bracket 61 having a substantially L-shaped cross section is fixed to the inner peripheral surface of the starboard door frame main body 241 and the indoor side surface of the outdoor starboard door frame 243 with screws b1, b2, and the like. The outdoor wall reinforcing member 63 is fixed to the inner peripheral side of the mounting bracket 61 by a screw b3 or the like. The mounting bracket 61 is short and provided at a plurality of locations along the longitudinal direction of the starboard door frame 24. In addition, it can fix still more firmly by fixing the attachment bracket 61 to the reinforcement member arrange | positioned in the hollow part of the starboard door frame main body 241 with a screw | thread.

The outdoor side wall reinforcing member 63 is made of a metal material such as an aluminum alloy, and the smoke return piece 63a that forms smoke return in cooperation with the smoke return piece 34b provided on the outdoor side surface of the starboard 34 of the shoji 3; It has the hollow part 63b and the fixing | fixed part 63c provided in a row by the outer peripheral side of the hollow part.
A first sub-reinforcing member 631 and a second sub-reinforcing member 632 made of a metal material such as stainless steel are disposed on the indoor side surface and the outdoor side surface of the outdoor side wall reinforcing member 63. The strength of the 63a portion is improved.
Specifically, the first auxiliary reinforcing member 631 is arranged so as to cover the indoor side surface of the outdoor wall reinforcing member 63 and a part of the inner side (outer peripheral side) of the smoke return piece 63a, and the second auxiliary reinforcing member 632 The outdoor side wall reinforcing member 63 is disposed so as to cover the inner peripheral side outdoor side surface, the outer side (inner peripheral side) surface of the smoke return piece 63a, and the indoor side surface.

A heating expansion material f1 is disposed on the first sub-reinforcing member 631 disposed on the indoor side surface so as to face the smoke return piece 63a, and the outdoor side surface of the hollow portion 63b of the outdoor side wall reinforcing member 63 is heated. An expansion material f2 is disposed.
Furthermore, the heating expansion material f3 is arrange | positioned at the outdoor side surface of the fixing | fixed part 63c.

  On the other hand, the starboard 34 of the shoji 3 is provided with a reinforcing member made of a metal material such as stainless steel so as to cover the outdoor side surface of the outdoor smoke return piece 34b, and a heating expansion material f4 is arranged on the reinforcing member. Has been. Further, a reinforcing member made of a metal material such as stainless steel is disposed on the inner surface of the panel frontage.

In the joinery of this embodiment as described above, the following effects can be obtained.
The starboard door frame 24 provided with the door pocket 6 maintains the high heat insulating performance by arranging the indoor side starboard door frame 242 and the indoor side wall member 62 made of synthetic resin on the indoor side, and also has an outdoor side wall member 64 on the outdoor side. By disposing the outdoor side wall reinforcing member 63 made of a metal material so as to cover the indoor side, the indoor / outdoor communication in the door pocket 6 portion can be suppressed and the fire resistance performance can be improved in the event of a fire.

  And since the outdoor side wall reinforcement member 63 is being fixed to the starboard door frame 24 via the attachment bracket 61 which consists of metal materials, it can be fixed to the outer peripheral surface of the deep door pocket 6 easily and firmly, Since the mounting bracket 61 is fixed to the inner peripheral surface of the starboard door frame main body 241 that is a prospective wall of the starboard door frame 24, the outdoor wall reinforcing member 63 is supported at a portion that is relatively hardly affected by the flame. It is possible to prevent the outdoor wall reinforcing member 63 from falling off during a fire. The mounting bracket 61 may be fixed to the starboard door frame 24 only by fixing the starboard door frame main body 241 to the inner peripheral surface, but the mounting bracket 61 may be fixed to the inner peripheral surface of the starboard door frame main body 241 and the outdoor side. By fixing to the indoor side surface of the starboard door frame 243, the connection between the starboard door frame main body 241 and the outdoor starboard door frame 243 can be reinforced by the substantially L-shaped mounting bracket 61. Strength can be increased.

  Further, the outdoor side wall reinforcing member 63 is provided over substantially the entire length of the starboard door frame 24 in the longitudinal direction, and the smoke return piece 63a is integrally formed on the inner periphery, so that the outdoor side wall reinforcing member 63 is provided. Thus, the smoke return can be easily formed while improving the fire resistance of the outdoor side of the door pocket 6. Furthermore, by providing a sub-reinforcing member made of a metal material such as stainless steel so as to cover the indoor side and / or the outdoor side of the outdoor wall reinforcing member 63, it is possible to form a smoke return piece that is relatively heat resistant and highly rigid. it can.

  Further, a heating expansion material f1 is disposed on the indoor side surface of the outdoor side wall reinforcing member 63 so as to expand toward the smoke flare formed in cooperation with the smoke flake piece of the shoji 3 and the starboard of the shoji 3 Since the heating expansion material f4 is disposed in the vicinity of the smoke return piece 34, it is possible to prevent the flame and smoke from entering by covering the smoke return portion with the expansion material in the event of a fire.

  In addition, since the heat expansion materials f2 and f3 are arranged on the outdoor side of the hollow portion 63b of the outdoor side wall reinforcing member 63 and on the outdoor side of the fixed portion 63c, the outdoor side of the door pocket 6 is covered by the heat expansion material f2 expanded in the event of a fire. Even when the outdoor starboard door frame 243 is deformed while the deformation of the outdoor wall of the door pocket 6 due to covering, flame or the like can be suppressed, as shown in FIG. 63 and the outdoor starboard door frame 243 can be closed, and the spread of fire can be suppressed.

In the embodiment described above, the metal reinforcing member 63 is provided on the outdoor side of the door pocket 6 by the mounting bracket 61, but the outdoor side surface of the indoor side wall member 62 that is the indoor side wall of the door pocket 6. A metal reinforcing member may be disposed on the wall, and further, the reinforcing member may be disposed on the finding walls on both the indoor side and the outdoor side. Moreover, there is no limitation in the part of the door pocket 6 covered with the metal outdoor side wall reinforcement member 63, You may just cover the weak part with respect to a flame among the finding walls, and you may comprise so that the whole may be covered.
In addition, the reinforcement member which consists of a metal material in this embodiment should just have tolerance with respect to a flame or heat rather than a to-be-reinforced member, The material is not limited. In addition, it is preferable to use the reinforcement member formed with metal materials, such as stainless steel which is hard to rust, as the reinforcement member arrange | positioned in a user's eye.
Moreover, in the said embodiment, although the door pocket is formed so that a part of the shoji 3 which covers the opening part provided in the door 2 may be accommodated, it is not limited to the said embodiment, It is directly on a building. A door pocket may be provided, or a door pocket that accommodates the entire shoji screen.
That is, the example of the joinery of the above embodiment is an example, and the joinery of the present invention is not limited to the door, and the kind of joinery is not limited at all.
