[0098] As described above, in the fire-resistant fitting of the present embodiment, since no reinforcing member is disposed within the glass opening that holds the periphery of the single-pane glass, construction is easy and is also economical. In addition, since heated foaming material is placed around the entire inside of the glass opening that holds the single-pane glass, it is possible to seamlessly prevent gaps from occurring between the single-pane glass and the glass opening, preventing communication between the inside and outside of the room, thereby improving fire resistance.

[0099] In particular, in the lower frame or bottom sill where the support members that support the single-pane glass are arranged, heated foaming material is arranged on the visible surface of the glass opening, so that the spaces between the support members can also be filled with heated foaming material, preventing communication between the inside and outside of the room. Furthermore, the drainage holes formed on the underside of the glass frontage are not blocked, and deterioration of the heat-foaming material due to condensation water or the like can be suppressed.

[0100] Furthermore, in sliding door fittings, the heated foam material placed at the glass opening of the inner screen is positioned closer to the inside of the room, and the heated foam material placed at the glass opening of the outer screen is positioned closer to the outside of the room, so the screen closest to the side where the fire has started can be quickly protected.

[0101] In addition, the frame is reinforced by placing a reinforcing member with an approximately U-shaped cross-section, which has opposing projected and visible surfaces above and below, within the hollow portion of the frame, and the reinforcing member is provided with a visible surface (rotation prevention wall portion) that is continuous with one of the projected surfaces above and below to prevent the reinforcing member from rotating, thereby preventing the reinforcing member from rotating within the hollow portion, stabilizing the reinforcing member and enabling strong reinforcement.

[0102] In each embodiment, the heat-foaming material attached to the frame or the housing may be attached to the frame or the housing in any manner, for example, it may be held by a holder formed on the frame or the housing, may be fixed by double-sided tape or adhesive, or may be fixed by screws or the like.

[0103] Furthermore, there is no limitation on the type of window.

[0104] Needless to say, the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]

Claims

[Claim 1] Heat foaming material is placed around the four sides of the glass opening that holds the single pane glass. A support member for supporting the lower edge of the single-pane glass is disposed without disposing a reinforcing member at least within a glass opening that holds the lower edge of the single-pane glass, The support member has a rectangular hollow cross section, The heating foam material to be placed within the glass opening that holds the lower edge of the single-pane glass is attached to the visible surface within the glass opening, The heated foam material foams in the event of a fire and seals the inside of the glass window that holds the single pane glass on all four sides. Fireproof fittings.
