If it is only exposed to the flame, the multilayer glass 3 may come off together with the integrated holding metal fitting 20 and the locking holding metal fitting 30. For this reason, according to the window unit 1 like this embodiment, it is provided in the hollow portions 11k, 12k, and 13k of the upper and lower horizontal members 11 and 12 and the left and right vertical members 13 made of synthetic resin that constitute the frame body 10. Since the integral holding metal fitting 20 and the frame side metal fitting 31 are fixed to a nonflammable reinforcing member 15 such as a metal such as iron or stainless steel, it is possible to prevent the multilayer glass 3 from coming off even when exposed to a flame. Is possible. The reinforcing member is not limited to a non-combustible reinforcing member, and the surface is first carbonized by a fire, and can be retarded from burning inside due to the heat insulating effect of the carbonized surface, for example, MDF, wood, etc. Any flame retardant reinforcing member may be used.

  According to the method for attaching the multilayer glass 3 using the window unit of the present embodiment, the integral holding metal fitting 20 and the frame side metal fitting 31 are attached to the frame body 10, and the multilayer glass 3 is opposed to the frame material of the integral holding metal fitting 20. Inserted between the wall 22 and the pressing edge facing wall 23, the outer peripheral end portion of the indoor side surface 3 a of the multilayer glass 3 and the inwardly extending piece 34 are opposed to each other, and the locking metal fitting 36 is attached from the outdoor side of the multilayer glass 3. By latching to the frame side metal fitting 31, the multilayer glass 3 can be held by the integral holding metal fitting 20 and the locking holding metal fitting 30 so that they cannot be easily removed.

  In the above-described embodiment, the window unit 1 for the FIX window in which the multilayer glass 3 is attached to the frame member so as not to be opened and closed has been described as an example. However, the present invention is not limited thereto, and the shoji is attached with a face material. It does not matter. In this case, the frame-shaped member becomes a ridge constituting the shoji.

  In the said embodiment, although the example which was set as the laminated glass 3 which formed two sheet glass facing each other with the space | interval spaced apart from each other was demonstrated, the face material is one glass plate, Alternatively, it may be a multi-layer glass in which three or more sheet glasses face each other at an interval and are integrally formed. Further, the face material is not limited to glass, and may be a plate-like interior material or exterior material.

  In the method for attaching the multilayer glass 3 in the above embodiment, the method for attaching the multilayer glass 3 from above to the frame 10 placed on a flat place has been described. However, the multilayer glass 3 is attached to the frame 10 attached to a building or the like. 3 may be attached.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
