As described above, in the joinery of the first to fourth embodiments, the following effects can be obtained.
Arrange the heating expansion material arranged in the panel opening of the lower rod 22 and the right and left rods 23, 24 so that at least a part thereof faces the fireproof panel on the outdoor side of the panel body (multi-layer panel). Therefore, it expands quickly with respect to the flame from below, and the outdoor fireproof panel can be firmly held.

  Even if the fireproof panel on the outdoor side is deformed and falls off due to the progress of the fire, the heating expansion material f1 disposed in the panel opening 212 of the upper lid 21 is directed toward the indoor panel 252. Since it is inflated and holds the indoor panel 252, it is possible to prevent the outdoor fireproof panel 251 and the indoor panel 252 from being lost simultaneously.

Further, by disposing the heating expansion material f1 disposed in the panel opening 212 of the upper lid 21 on the indoor side, the combustible gas having a small specific gravity that is generated and raised between the inner and outer glasses in the event of a fire is discharged to the outside of the room. Intrusion into the inside can be suppressed.
And since the elongate reinforcement member is not arrange | positioned over four rounds in each panel opening of the upper and lower eaves 21 and 22 and the right and left eaves 23 and 24, while being able to restrain the weight of joinery, a manufacturing process Increase and price increase can be suppressed.

And like the upper collar 21 and the lower collar 22 of the 1st, 3rd embodiment, and the starboard 23 of the 3rd, 4th embodiment, a heating expansion material is used for the wall (outside wall part or outdoor wall part) of a panel frontage. By disposing on the indoor side wall portion, the heating expansion material expands between the bottom wall portion of the panel opening and the small edge surface of the panel body, so that the space can be reliably closed.
Particularly, by disposing the heating expansion material f2 disposed in the panel opening 222 of the lower rod 22 in the outdoor side wall portion 222b, good drainage by the drainage hole 221b can be maintained.

  In addition, like the first and second embodiments on the right and left sides 23 and 24, by disposing the heating expansion material on the prospective wall (bottom wall portion) of the front panel of the panel, the expansion of the expansion in the event of a fire The panel can be sandwiched so that both sides of the panel are compressed by the material, thereby improving the shielding property.

In each of the above embodiments, a holder is formed at the panel opening, and the heating expansion material is set by the holder. However, the heating expansion material is not limited to being installed by the holder. For example, the heat expansion material may be attached to the panel opening with an adhesive or the like, or may be fixed with a screw or the like.
In addition, when using three or more multi-layer panels, only one panel with only the outdoor end in the prospective direction is an expensive fireproof panel, and all the remaining panels are relatively inexpensive non-fireproof panels. It is preferable because the effect can be exhibited at a low price.

In addition, in the joinery of each said embodiment, what can maintain fireproof performance with a heating expansion material, without arrange | positioning a long reinforcement member in all the panel frontage of an upper, lower arm, right, and port side. However, for example, a short auxiliary member or the like having a slight reinforcing function may be disposed on any of the ridges.
Further, the member for holding the multilayer panel is not limited to the glazing channel, and the inside and outside of the panel may be sandwiched between the outdoor bead and the indoor bead, respectively, or with an adhesive such as curable caulking or hot melt. The panel may be sandwiched inside and outside while bonding. Alternatively, the panel may be sandwiched by placing a bead on one of the inside and outside of the panel and an adhesive on the other.

  Moreover, the example of the joinery of the said embodiment is an example, Comprising: The joinery of this invention is not limited to a vertical sliding window, A horizontal member (upper / lower frame and an up-and-down frame) and a saddle material (an eaves and an eaves frame) Can be adopted as a construction of various opening and closing windows or fitting windows, etc., and the kind of joinery is not limited at all is not.

  Needless to say, the embodiments described above do not limit the invention described in the claims, but are treated as examples.
