[0033] Next, the end portion of the panel 10B on the side of the vertical frame 24 is inserted into the panel mounting groove 24A and erected in a knockdown manner as shown in FIG. 6(B). After that, the bead member 13 is attached to the resin vertical frame member 34. After attaching a dropout prevention fitting 54 provided with a first heat-expandable material 55D to the metal intermediate frame member 35, a resin intermediate frame member 36 provided with a bead member 13 is attached. After attaching dropout prevention fittings 51 and 52 provided with first heat-expandable materials 55A and 55B to the metal sleeve frame members 37 and 39, resin sleeve frame members 38 and 40 provided with bead members 13 and 13 are attached. Thus, the attachment of the panel 10B to the panel mounting grooves 24A, 25A, 26A, and 27A is completed.

[0034] According to the first embodiment described above, the dropout prevention fittings 51, 52, 53, and 54 attached to the fixed window portion 1B include opposing portions 511, 521, 531, and 541 provided over the entire length of the respective frames 24, 25, 26, and 27, and fixing portions 512, 522, 532, and 542. First heat-expandable materials 55A, 55B, 55C, and 55D are provided over the entire length of the respective frames 24, 25, 26, and 27 on the opposing portions 511, 521, 531, and 541. The dropout prevention fittings 52, 53, and 54 are fixed by screws 14B, 14C, and 14D with the fixing portions 522, 532, and 542 outside the panel mounting grooves 25A, 26A, and 27A. With such a configuration, it is possible to prevent flames from passing between each of the frames 24, 25, 26, 27 and the panel 10B through the first heat-expandable materials 55A, 55B, 55C, 55D that are expanded over the entire length of each of the frames 24, 25, 26, 27, and fire prevention performance can be ensured. Further, after arranging the panel 10B in the panel attachment groove 24A of the vertical frame 24 to which the anti-drop fitting 51 is attached, the anti-drop fittings 52, 53, 54 are fixed to the respective frames 25, 26, 27 by screws 14B, 14C, 14D on the outside of the panel attachment grooves 25A, 26A, 27A, and the resin intermediate frame member 36 and the resin sleeve frame members 38, 40 can be connected to the metal intermediate frame member 35 and the metal sleeve frame members 37, 39, and the fixed window portion 1B can be easily assembled.

[0035] Since each of the frames 24, 25, 26, 27 is composed of the outdoor-side frame members 33, 35, 37, 39 made of metal having the outdoor finding surface facing portion and the prospect surface facing portion, and the indoor-side frame members 34, 36, 38, 40 made of resin having the indoor finding surface facing portion, the heat insulation property of the fixed window portion 1B can be improved. Since the anti-drop fittings 51, 52, 53, 54 are configured such that the first heat-expandable materials 55A, 55B, 55C, 55D face the finding surface on the indoor side of the panel 10B, passage of flames to the outside can be further suppressed. In particular, by fixing the anti-drop fittings 51, 52, 53, 54 to the metal frame members 33, 35, 37, 39 with little deformation due to the heat of flames, the fire prevention performance can be enhanced.

[0036] The fixing portions 512, 522, 532, 542 of the anti-drop fittings 51, 52, 53, 54 are provided so as to protrude from a plurality of locations along the longitudinal direction of each of the frames 24, 25, 26, 27. For this reason, weight reduction and material reduction of the anti-drop fittings 51, 52, 53, 54 can be achieved. Further, since a part of the fixing structure between the metal sleeve frame members 37, 39 and the resin sleeve frame members 38, 40 is cut out and the fixing portions 512, 522, 532, 542 are fixed to the cut-out portions, the anti-drop fittings 51, 52, 53, 54 can be attached without changing the fixing structure between the metal sleeve frame members 37, 39 and the resin sleeve frame members 38, 40.

[0037] In the fixed window portion 1B, in addition to the first heat-expandable materials 55A, 55B, 55C, 55D, second heat-expandable materials 56A, 56C1, 56C2, 56D, third heat-expandable materials 57B, and fourth heat-expandable materials 58C, 58D are provided over the entire length of the corresponding frames, so that the fireproof performance can be further enhanced.

[0053] [Summary of the Invention] The fitting of the present invention includes a frame body composed of upper, lower, left, and right frames, a panel disposed in a panel mounting groove of the frame body, and metal anti-drop parts respectively provided on the frames for pressing the panel. The frame includes an outdoor frame member on the outdoor side and an indoor frame member on the indoor side that forms the panel mounting groove by being connected to the outdoor frame member. At least one of the outdoor frame member and the indoor frame member is a metal frame member. The anti-drop part is provided over the entire length of the frame and includes an opposing part facing the finding surface of the panel and a fixing part fixed to the frame. The opposing part is provided with a first heat-insulating foam material over the entire length of each frame. At least three of the anti-drop parts provided on the frames are anti-drop metal fittings in which the fixing part is fixed outside the panel mounting groove. According to the present invention, since the first heat-insulating foam material is provided over the entire length of each frame, it is possible to prevent flames from passing between the upper, lower, left, and right frames and the panel, ensuring fire prevention performance. Further, for example, while an anti-drop part is provided on the right frame, after placing the panel in the panel mounting groove of the right frame with the anti-drop metal fittings not attached to the upper, lower, and left frames, the anti-drop metal fittings can be fixed to the frames by fixing tools outside the upper, lower, and left panel mounting grooves, and the upper, lower, and left outdoor frame members can be connected to the indoor frame members, enabling easy assembly of the fitting.

[0054] In the fitting of the present invention, the panel mounting groove is composed of an outdoor finding surface opposing part facing the finding surface on the outdoor side of the panel, a prospective surface opposing part facing the prospective surface of the panel, and an indoor finding surface opposing part facing the finding surface on the indoor side of the panel. The outdoor frame member is a metal frame member having the outdoor finding surface opposing part and the prospective surface opposing part, the indoor frame member is a resin frame member having the indoor finding surface opposing part, and it is preferable that the anti-drop part is configured such that the first heat-insulating foam material faces the finding surface on the indoor side of the panel. According to the present invention, the heat insulation property of the fitting can be improved. Further, by opposing the first heat-insulating foam material to the finding surface on the indoor side of the panel, the passage of flames to the outside can be more suppressed.

[0055] In the fitting of the present invention, it is preferable that the fixing portion of the anti-detachment fitting is fixed to the metal frame member. According to the present invention, since the first heat-expandable material is fixed to the metal frame member with little deformation due to the heat of a fire, the fireproof performance can be enhanced.

[0056] In the fitting of the present invention, it is preferable that the fixing portion of the anti-detachment fitting is provided so as to protrude from a plurality of locations along the longitudinal direction of the frame. According to the present invention, weight reduction and material reduction of the anti-detachment fitting can be achieved.

[0057] In the fitting of the present invention, it is preferable that a second heat-expandable material is provided over the entire length of the frame at the portion facing the prospective surface of the panel mounting groove provided in the upper and left and right frames. According to the present invention, in both the case of combustion from the indoor side and the case of combustion from the outdoor side, the through-hole formed between the prospective surface of the panel and the frame can be blocked by the second heat-expandable material, and the fireproof performance can be further enhanced.

[0058] In the fitting of the present invention, a plurality of setting blocks for holding the panel are provided at predetermined intervals in the panel mounting groove provided in the lower frame, and it is preferable that a third heat-expandable material is provided over the entire length of the frame at the portion facing the outdoor finding surface of the panel mounting groove provided in the lower frame. According to the present invention, the through-hole formed in the portion where the setting block is not provided in the panel mounting groove of the lower frame can be blocked by the third heat-expandable material at the time of a fire, and the fireproof performance can be further enhanced.

[0059] In the fitting of the present invention, it is preferable that a fourth heat-expandable material is provided over the entire length of the frame at the portion facing the outdoor finding surface of the panel mounting groove provided in the left and right frames. According to the present invention, for example, during combustion from the indoor side, the first heat-expandable material expands to prevent the passage of flames between the frame and the panel, and after the first heat-expandable material expands, the fourth heat-expandable material expands to prevent the passage of flames between the frame and the panel. Thus, by the first heat-expandable material and the fourth heat-expandable material expanding with a time difference, even if a gap is formed between the first heat-expandable material and the frame due to thermal deformation of the panel or the frame before the fourth heat-expandable material expands, the subsequent expansion of the fourth heat-expandable material can close the gap, and the fireproof performance can be further enhanced.
