Therefore, as shown in FIG. 12(b), the heated foam material 7 is first foamed toward the indoor and outdoor directions. After that, heat is indirectly transmitted from the reinforcing member 25 to the heating foaming material (prospect direction foaming material) 8 attached to the lower surface of the heating foaming material mounting member 29, so that the heating foaming material 8 shown in FIG. The material 8 expands downward and compresses the previously expanded longitudinal foam material 7 from above. In this manner, the heat foaming materials 7 and 8 that are foamed in the mutually intersecting directions are compressed together, so that the heat foaming materials 7 and 8 can be densely foamed within the hollow portion 6 . In particular, the longitudinal foam material 7 is foamed first, and the prospective foam material 8 is foamed later to compress the longitudinal foam material 7, so that the foaming of the heating foam materials 7 and 8 is not hindered. The foam can be densely and evenly distributed in the hollow portion 6. - 特許庁As a result, even when the heating foaming material cannot be placed facing the holes (screw insertion holes 23, 23, door roller adjusting hole 24) to be closed, those holes can be reliably closed with the foamed heating foaming materials 7, 8. can.

As described above, in this fitting, the heating foam mounting members 2a, 2b, and 2c are incombustible or flame-retardant and have elasticity, and the heating foam members 3a, 3b, and 3c are mounted on either surface of the members. Since it is held in a compressed state in the hollow portions 4a, 4b, 4c of the shaped members (lower rails 1a, 1b), the heated foaming member mounting members 2a, 2b, 2c can be shaped without screwing or bonding. The heating and foaming members 3a, 3b, 3c can be easily installed simply by pushing them into the hollow portions 4a, 4b, 4c of the members 1a, 1b. Further, by forming the heating foam mounting members 2a, 2b, and 2c to be large, the same heating foam mounting members 2a, 2b, and 2c can be used even if the hollow portions 4a, 4b, and 4c have slightly different shapes. be able to. If the heating foam mounting members 2a, 2b, 2c have self-extinguishing properties, even if the heating foam mounting members 2a, 2b, 2c are ignited, the fire will be immediately extinguished and the flame will not spread.

In addition, this fitting includes shaped members (joint frames 5a and 5b) and heating foam members 7 and 8 provided in hollow portions 6 of the shaped members 5a and 5b. a longitudinal foam 7 provided along the longitudinal direction of the hollow portion 6; , and one of the longitudinal foam material 7 or the prospective foam material 8 compresses the other when foamed, so that the heated foam materials 7, 8 are densely foamed in the event of a fire.
Further, this fitting comprises shaped members (joint frames 5a, 5b) and heating foam members 7, 8 provided in hollow portions 6 of the shaped members 5a, 5b. (screw insertion hole 23, door roller adjustment hole 24), and has a foaming material that foams quickly and a foaming material that foams later than that, and the foaming material 8 that foams slowly foams quickly. Since the member 7 is compressed, the heated foamed materials 7 and 8 are densely foamed, and the foamed heated foamed materials 7 and 8 can reliably close the covered portions 23 and 24 .

The invention is not limited to the embodiments described above. Shapes include all members of fittings, such as frames, stiles, mullions, and mullets. Heat foaming materials can be provided to close gaps between members, holes and notches formed in members, and any gaps that may allow flame or smoke to communicate in the event of a fire. It can be appropriately changed according to the gap or the like. The heating foam mounting member may be of any material as long as it is incombustible or flame-retardant and has elasticity.
