Even if the sealing material 31A backed up by 31B is applied, the sealing may be insufficient. Therefore, a corner plate 35 made of rubber, plastic, metal plate or the like is applied to the outdoor side surfaces of the adjacent fixing pieces 1E, 2E, 3E, 4E across the outside (see FIG. 1) and used for backup of the sealing material 31A. Is preferred.
[0016]
[Face support frame]
The face material support frame is for supporting (holding) a face material such as glass or a panel on a sash frame, and examples thereof include a shoji frame.
[0017]
As shown in FIGS. 2 and 3, the face material support frame 20 in the present embodiment mainly includes upper and lower horizontal support frame members 21 and 22 and left and right vertical support frame members 23 and 24. The upper horizontal support frame material 21 and the lower horizontal support frame material 22 are made of the same mold material (the same cross section), and the left vertical support frame material 23 and the right vertical support frame material 24 are the same mold material (the same cross section). Consists of. Thereby, the manufacturing cost is reduced. The reason why the shapes of the upper and lower horizontal support frame members 21 and 22 and the left and right vertical support frame members 23 and 24 are different is that it is necessary to fit the face material 8, and it does not deny that they are the same shape.
[0018]
The upper and lower horizontal support frame members 21 and 22 are provided on the outer side end portions of the main body pieces 21C and 22C, and the outdoor side pieces 21A and 22A projecting inward are provided on the inner side end portions of the main body pieces 21C and 22C. Overhanging indoor side pieces 21B and 22B are respectively formed. The outdoor-side pieces 21A and 22A and the indoor-side pieces 21B and 22B are separated from each other, and are formed as stagnation grooves for the face material 8 such as glass.

On the other hand, the left and right vertical support frame members 23 and 24 are provided at the outdoor side ends of the main body pieces 23C and 24C, and the outdoor side pieces 23A and 24A projecting inward are provided at the indoor side ends of the main body pieces 23C and 24C. Indoor side pieces 23B and 24B projecting in the direction are respectively formed. The outdoor side pieces 23A and 24A are locking portions of the pressing edges 9 and 9, and a space between the pressing edges 9 and 9 and the indoor side pieces 23B and 24B is a squeezing groove of the face material 8. The supporting gaskets 11, 11,... Of the face material 8 are attached to the indoor side pieces 21B, 22B, 23B, 24B, the outdoor side pieces 21A, 22A, and the pressing edges 9, 9, respectively. A setting block 12 for supporting the face material 8 is installed on the main body piece 22 </ b> C of the lower horizontal support frame member 22.
[0020]
Further, along the contact surface of the face material support frame 20 with the sash frame 10, in this embodiment, along the outdoor end of the main body pieces 21C, 22C, 23C, 24C, an elastic member such as rubber, or a sealing material A liquid-tight material 25 made of butyl sheet or the like is attached. This prevents liquid such as water from passing through the sash frame 10 and the face material support frame 20 and entering the room. In the present invention, as described later, the position where the face material support frame can be attached to the sash frame in the indoor / outside direction changes, but the mounting position of the liquid-tight material is in contact with the sash frame of the face material support frame. Since the position is along the outdoor end of the surface, the above effect (liquid tightness) is always maintained.
[0021]
Liquid tight means a state where liquid such as water cannot pass. When the liquid is water, it is generally called watertight.
[0022]

In this respect, for example, it is possible to attach a reinforcing plate (not shown) to the inner piece 1A that is not thick and attachable, and attach the face material support frame 20 to the attachable shape portion by screwing or the like. Conceivable. However, from the viewpoint of reducing the number of components of the sash unit and facilitating manufacturing, and reducing the assembly process and facilitating the work, it is preferable to increase the thickness as in the present embodiment. Further, from the viewpoint of easy attachment of the face material support frame 20, it is preferable that the contact surfaces of the inner pieces 1A, 2A, 3A, and 4A with the face material support frame 20 be flat, In the embodiment, the thicknesses of the upper and lower horizontal frame members 1 and 2 and the left and right vertical frame members 3 and 4 protrude toward the inner space.
[0027]
The thickness of the thick portions 1a, 1a,... Of the inner pieces 1A, 2A, 3A, 4A of the sash frame 10 is not particularly limited. For example, the design can be appropriately performed from the viewpoint of the strength of the sash frame, the material cost, the ease of design of the mold material, and the like.
[0028]
There is no particular limitation as to what range the predetermined range L of the wall thickness is set to. Of course, if the predetermined range L is short, it leads to a reduction in material cost. Conversely, if the predetermined range L is long, it leads to an improvement in material cost. In the present embodiment, as shown in FIG. 4B, the outdoor pieces 1C, 2C, 3C, and 4C of the sash frame 10 and the outdoor pieces 21A, 22A, 23A, and 24A of the face material support frame 20 are combined. As shown in FIG. 4 (4), the indoor side pieces 1D, 2D, 3D, and 4D of the sash frame 10 and the indoor side pieces 21B, 22B, 23B, and 24B of the face material support frame 20 To the position where can be aligned.
