  A glass detachment prevention member 40 is disposed on the expected surface of the housing 30 (the upper rod 31, the lower rod 32, the door-end-side vertical rod 34, and the hanging-source-side vertical rod 33). The glass detachment preventing member 40 regulates movement of the multilayer glass 25 in the out-of-plane direction. A plurality of spaces are arranged on the expected surface of the housing 30 at intervals.

  Next, the FIX window 120 will be described. The FIX window 120 is located on the inside of the frame 10 on the opposite side of the shoji 20 across the bridge 16. The upper frame 11, the lower frame 12, the FIX side vertical frame 14, and the square 16 function as a housing (frame) of the FIX window 120.

  The FIX window 120 comprises a double glazing 125 comprising an outdoor glass 125a and an indoor glass 125b. A spacer 126 or the like is disposed between the outdoor glass 25a and the indoor glass 25b. As the outdoor side glass 125a, one having a heat resistance relatively higher than that of the indoor side glass 125b is used. In the present embodiment, as in the case of the multilayer glass 25 of the shoji 20, a mesh glass is used for the outdoor glass 125a, and a low-E glass is used for the indoor glass 125b.

  A pressing edge member 127 made of resin for holding the multilayer glass 125 is fitted and fixed to the outer finding surface of the upper frame 11, the lower frame 12, the FIX side vertical frame 14, and the horizontal plate 16. Further, a glass stopper member 128 is disposed on the indoor side of the upper frame 11, the lower frame 12, the FIX side vertical frame 14, and the horizontal plate 16. The glass stopper member 128 is located on the opposite side of the pressing edge member 127 with the multilayer glass 125 interposed therebetween in the expected direction.

  A glass detachment prevention member 140 is also disposed on each of the expected surfaces of the upper frame 11, the lower frame 12, the FIX side vertical frame 14 and the end face of the double glazing 125 in the horizontal plate 16. The glass disengagement member 140 regulates movement of the multilayer glass 125 in the out-of-plane direction. A plurality of spaces are arranged on the expected surface of the upper frame 11, the lower frame 12, the FIX-side vertical frame 14, and the bridge 16. These glass detachment preventing members 140 are fastening members (shown in the drawings) to metal core members (upper frame core member 11 d, lower frame core member 12 d, vertical frame core member 14 d and horizontal core member 16 e) disposed inside the frame. It is fixed by fastening via an abbreviation). In addition, setting blocks 99 are disposed on each of the prospective faces of the FIX side vertical frame 14 and the side board 16.

  Next, the configuration of the setting block 90 for supporting the double layered glass 125 of the FIX window 120 from below and the heating foam material 91 disposed adjacent to the setting block 90 will be described. FIG. 5 is an enlarged vertical sectional view showing a setting block 90 applied to the fixture 1 of the present embodiment and the periphery thereof. FIG. 6 is a perspective view showing a setting block 90 applied to the fixture 1 of the present embodiment and the periphery thereof.

  As shown in FIGS. 5 and 6, one or more setting blocks 90 are disposed between the lower end surface of the multilayer glass 125 and the expected surface 12 g of the lower frame 12. When arranging a plurality of setting blocks 90, for example, they are arranged at intervals in the left-right direction. The setting block 90 is formed in a rectangular shape by a resin such as polyvinyl chloride (PVC). The setting block 90 is fixed to the lower frame 12 by means such as double-sided tape or adhesive. The setting block 90 may be fixed to the lower frame 12 by mechanical means such as a fastening member such as a screw or a pressing member.

  In the present embodiment, the outdoor side surface of the setting block 90 is disposed substantially flush with the outdoor side surface of the outdoor side glass 125a. Further, the indoor side surface of the setting block 90 is in a positional relationship facing the outdoor side surface of the extending portion 12 e of the lower frame 12.

  The heating foam material 91 is disposed adjacent to the outside of the setting block 90 on the expected surface 12g of the lower frame 12. The heating foam material 91 is made of a material that is expanded by heat using an epoxy resin or the like, and has a band shape.

  The length of the heating foam material 91 in the left-right direction is substantially equal to the length of the width of the setting block 90 in the left-right direction. Further, the length in the expected direction of the heating foam material 91 is a length that covers from the setting block 90 to the outer end of the expected surface 12 g of the lower frame 12. The heating foam material 91 is also fixed to the lower frame 12 by means such as double-sided tape or an adhesive. The heating foam material 91 may be fixed to the lower frame 12 by mechanical means such as a fastening member such as a screw or a pressing member.

According to the configuration of the embodiment described above, the following effects can be obtained.
The fixture 1 foams outside the expected direction of the setting block 90 made of resin, which is disposed between the lower frame 12 and the multi-layer glass 125 constituting the frame 10, and the setting block 90 on the expected surface 12g of the lower frame 12. And a heating foam material 91 disposed adjacent to the surface (flat portion) upward.

  Thus, the lower end of the multi-layer glass 125 is normally supported by the upper surface of the setting block 90, and the foamed surface is directed upward before the resin setting block 90 melts when the temperature becomes high when a fire occurs. The heating foam material 91 foams. The space between the pressing edge member 127 and the setting block 90 and the space between the pressing edge member 127 and the outdoor side (the outdoor side glass 125a) of the multilayer glass 125 are formed by foaming, and the setting block is made from the outdoor side Heat transfer to 90 can be suppressed and melting of the setting block 90 can be delayed. In particular, the falling of the multilayer glass 125 can be delayed when the outdoor side is exposed to a fire, and the setting block 90 can be effectively protected.

  Further, in the present embodiment, the length of the heating foam material 91 in the left-right direction substantially matches the length of the setting block 90 in the left-right direction on the outdoor side.

  As a result, it is possible to reduce the amount of the heating foam material 91 required to delay the outdoor drop of the multilayer glass 125, and to realize a configuration for delaying the outdoor drop of the multilayer glass 125 at low cost.

  As mentioned above, although the preferable embodiment of this invention was described, this invention is not restrict | limited to the above-mentioned embodiment, It can change suitably.

  Although the setting block 90 holding the double layer glass 125 of the FIX window 120 has been described as an example in the above embodiment, the invention can also be applied to a fixture provided with an openable / closable shoji such as a vertical turning window or a horizontal turning window. For example, the heating foam is disposed on the outer surface of a setting block that is disposed on the lower surface of the lower shell of the casing that houses the multilayer glass inside and supports the multilayer glass of shoji from below. That is, the frame in which the setting block and the heating foam material are disposed may be a casing of a shoji. Thus, the present invention is applicable to various fixtures that need to hold multi-layer glass.

  Moreover, it is not restricted to the structure of the upper frame 11, the lower frame 12, the shoji side vertical frame 13, and the FIX side vertical frame 14 demonstrated by the said embodiment, The structure of the frame 10 can be changed suitably. For example, a metal cover member such as an aluminum profile may be disposed on one or both sides of the frame (upper frame, lower frame, pair of left and right vertical frames) in the expected direction indoor side and outdoor side. .
