Conventionally, as a window frame, the one mainly made of a metal frame made of aluminum or the like has been the mainstream, but in recent years, a composite window frame in which an indoor portion of a metal frame is covered with a resin frame made of a resin having low thermal conductivity. Has been proposed. This composite window frame mainly has a structure in which the indoor side of a metal frame is covered with a resin frame. With this structure, the heat insulating property is improved, so that dew condensation on the indoor side can be suppressed, and the visual coldness peculiar to the metal frame is not felt. In addition, since the shape and color can be more easily varied as compared with the metal frame, there is also a characteristic that the design property on the indoor side can be easily improved by having the integration with the indoor decoration.
[0003]
As an edge structure for fixing a panel body such as a glass plate in such a composite window frame, for example, a structure shown in a longitudinal sectional view in FIG. 4 has been proposed. The edge structure of the composite window includes a composite window frame including an aluminum metal frame 101 framed in a substantially rectangular shape from the upper and lower and left and right frames, and a resin frame 102 covering an exposed portion of the metal frame 101 on the indoor side. On the other hand, the panel body 103 is fitted in a killed shape.
[0004]
The resin frame 102 has a fitting groove 104 formed in the opposite resin frame side along the longitudinal direction, and the metal frame 101 has a substantially L-shaped cross section extending to near the end of the panel body 103. Contact piece 105 is formed. In the fitting groove 104 of the resin frame 102, an edge member 106 molded of vinyl chloride, acrylic resin, or the like can be attached. A bead member 106 a is provided between the contact piece 105 and the panel body 103 and between the pressing member 106 and the panel body 103.
[0005]
In such a structure, the incorporation of the panel body 103 into the composite window frame has been performed in the following procedure. First, an outdoor bead material is attached to the contact piece 105 of the metal frame 101 at the factory, and the setting block 107 is placed and fixed on the lower frame of the metal frame 101. Then, at the construction site, the panel body 103 is placed on the setting block 107 of the lower frame, and the ridge member 106 is fixed. Then, finally, the bead material on the indoor side is attached between the bezel member 106 and the panel body 103, and the incorporation of the panel body 103 is completed.
[0006]
By the way, a building structure adopting a window frame as described above may be required to have a fireproof specification depending on a fire protection standard stipulated by the Building Standard Law or the regulations for a district where the building structure is built. . In the building structure of the fireproof specification, the conditions that are recognized as the fireproof specification are defined for the components constituting the structure, and the conditions must be satisfied.
[0007]
Conditions required for a fire-resistant window frame are that a metal frame is provided on the outdoor side and the indoor side and the panel body is covered with the metal frame, and that the setting block is inflammable. That at least one of the bead material on the outdoor side and the indoor side is flame-retardant, that the bead material having flame retardancy is supported by a metal frame, and the like.
[0008]
[Problems to be solved by the invention]
However, the above-mentioned conventional edge structure of the composite window has the following problems. That is, in order to provide a window frame of a fireproof specification, it is necessary to satisfy the above-mentioned conditions, and it is necessary to improve a conventional edge structure of a composite window. For example, in order to make the conventional composite window frame as shown in FIG. 4 fireproof, it is necessary to make the setting block and the bead material on the outdoor side flame-retardant, and to provide a metal frame on the indoor side. .
[0009]
However, since the bead material on the outdoor side is attached at the factory as described above, the bead material on the outdoor side is made flame-retardant only for the window frame of this prevention specification, and the bead on the outdoor side is used for the non-fireproof window frame. If the material is made non-flame-retardant, it is necessary to replace the bead material according to the type of the window frame, and thus there is a problem that productivity in a factory is hindered. On the other hand, flame-retardant bead materials can be attached to all window frames, but flame-retardant bead materials are more expensive than non-flame-retardant bead materials, and fire-resistant Because the window frame is less demanding than the non-fireproof window frame, it contributes to an increase in the cost of the entire window frame.
[0010]
