The panel body 5 is hold | maintained at the panel body holding groove | channel 43 via the Grechan 8 formed in the cross-sectional concave shape.

The indoor side surface of the metal vertical gutter 41 constituting the frame side vertical gutter 40 is the bottom wall 43 a of the panel body holding groove 43.
From the bottom wall 43a of the panel body holding groove 43 to the outside of the panel body holding groove 43, and the outside extending portion 41b extending from the bottom wall 43a of the panel body holding groove 43 to the outside. The indoor extending portion 41a, the outdoor extending portion 41b, and the bottom wall 43a form a concave cross section that opens to the outer peripheral side. The fin portion 12 c of the vertical frame 12 is swallowed into this region, and the bottom wall 43 a that is the outer peripheral surface of the frame-side vertical rod 40 faces the inner peripheral surface of the vertical frame 12 that constitutes the frame body 1.

A heating foam material 45 and a fixing member 70 that holds the heating foam material 45 are provided on the surface of the bottom wall 43 a that constitutes the frame side vertical rod 40 toward the outer peripheral side. The heated foam material 45 is a sheet-like member that expands when heated to a predetermined temperature, for example, 200 ° C. or higher. The fixing member 70 is made of steel or aluminum and holds one side portion of the heating foam material 45.

The fixing member 70 includes a fixed surface portion 71 that contacts and is fixed to the bottom wall 43a, and a fixed surface portion 71.
And a holding portion 73 that is continuous with the fixed surface portion 71 through the step portion 72. The holding portion 73 is a surface parallel to the fixed surface portion 71 and forms a gap portion 74 between the bottom wall 43a. In this gap 74, the heating foam 4
The heated foam material 45 is held by storing the side portion 5.

FIG. 4 shows a front view of the fixing member 70. The fixing member 70 is formed in a long shape along the longitudinal direction of the frame side vertical rod 40.

In the vicinity of the lower end portion of the fixed surface portion 71, a heating foam material 75 is disposed. Further, a stepped portion 72 and a holding portion 73 continuous with the stepped portion 72 are formed in the central region in the longitudinal direction of the fixed surface portion 71.

In FIG. 5, the side view seen from the outer peripheral side of the frame side vertical rod 40 which attached the fixing member 70 and the heating foam material is shown. As shown in this figure, the fixing member 70 is fixed from the vicinity of the upper end portion of the frame-side downboard 40 to the vicinity of the lower end portion thereof, and has a long shape over the region between the upper and lower end fixing portions 71a and 71a of the fixing member 70. The heating foam material 45 is disposed. The heating foam material 45 is sandwiched between the holding wall 73 of the fixing member 70 and the bottom wall 43a along one longitudinal side.

When a fire breaks out and the sash is exposed to a high temperature, the heating foam 45 provided on the frame-side vertical fence 40
Foams and expands in volume, and can close the gap between the bottom wall 43a of the frame-side vertical rod 40 and the inner peripheral surface of the vertical frame 12 along the longitudinal direction. Thereby, it is possible to prevent the heat and flame from penetrating through communication between the room and the outside through the gap between the frame body 1 and the external obstacle 3.

In the case where the heating foam material 45 is provided on the surface extending in the vertical direction, such as the bottom wall 43a of the frame side vertical rod 40, the heating foam material 45 is held and fixed by the holding portion 73 of the fixing member 70. Accordingly, it is possible to eliminate the need for fixing the screw to support the heating foam material 45 so that it does not fall, and the attachment work of the heating foam material 45 can be simplified.

Moreover, when the bottom wall 43a of the panel body holding groove 43 constitutes the outer peripheral surface of the frame side vertical rod 40 as in this embodiment, the space between the mounting surface of the heating foam 45 and the panel body 5 is used. Since there is almost no space, it is difficult to insert a screw. However, by eliminating the need for screw fixing, such a problem can be prevented.

As shown in FIG. 3, the panel body holding groove 43 of the frame side vertical rod 40 has a bottom wall 43 a and an outdoor side wall 4.

The 0 fixed surface portion 71 is fastened together by a fastener 46. That is, the fixing member 70 functions as a back plate of the panel body holding metal fitting 44. Since the panel body holding bracket 44 is fixed to the steel fixing member 70, the fixing strength can be sufficiently secured even in the event of a fire, and the holding state of the panel body 5 can be maintained.

Since the holding portion 73 for fixing the heating foam material 45 is formed on the fixing member 70 serving as the back plate of the panel body holding bracket 44, it is not necessary to provide a new part for fixing the heating foam material 45. In addition, since screw fixing is not necessary as described above, the number of parts can be reduced.

Moreover, since the fixing member 70 is formed in a long shape along the longitudinal direction of the frame side vertical rod 40,
It is possible to suppress deformation such as thermal expansion and bending of the frame-side vertical rod 40 when a fire occurs. Thereby, it can suppress that a clearance gap generate | occur | produces between the frame side vertical rod 40 and the frame 1, and can improve fire prevention performance. Thus, the fixing member 70 of the present embodiment functions as a back plate of the panel body holding metal fitting 44, a function of holding and fixing the heating foam material 45, and the frame-side vertical rod 4
Has the function of increasing the strength in the event of a zero fire.
