Description

  The present invention relates to a window installed in a building such as a house and a sash used for the window.

  In fire-proof areas where buildings such as houses are densely packed, it is necessary to install windows that are fire-proof, that is, have a high fire-preventing effect and a thermal effect-reducing effect. For this reason, the fire prevention window provided with the netted glass panel and the heat-resistant glass panel which are disclosed by patent document 1, for example is conventionally used. Conventional windows are generally single-glazed, and in addition, fire-resistant plastic extrusions are rarely used for firewood and frames, and even if cracks occur in a meshed glass panel, fire resistance is affected. There were few.

  However, in recent years, for the purpose of saving energy by improving heat insulation, pair glass (PG) as shown in the longitudinal sectional view of FIG. 14 and the transverse sectional view of FIG. Composite materials using and have come to be widely used for window frames and fences. 14 and 15, reference numerals 50 and 51 denote frames installed on the upper and lower edges of the building opening, respectively, and reference numeral 52 denotes a frame installed on the left and right edges of the building opening. 53 is a left and right vertical frame, and 54 and 55 are horizontal frames provided as an upper frame and a lower frame coupled between the vertical frames 53 and 53, respectively. It will be. Reference numerals 56, 57, and 58 denote synthetic resin extrusions provided on the interior sides of the vertical frame 53 and the horizontal frames 54 and 55, respectively, to improve heat insulation and prevent condensation, and to save energy. It is provided to give an effect.

  59 is a glass panel housed in a frame constituted by these extruded shapes, and this glass panel 59 is constituted by an outdoor side glass panel 60 and an indoor side glass panel 61, and these glass panels 60, 61. A spacer 62 made of a metal extruded profile as a spacer and a synthetic resin sealing material 63 also serving as an adhesive are interposed therebetween.

  Numerals 64 and 65 are pressing edges made of synthetic resin extruded shapes provided in combination with synthetic resin extruded shapes 56 and 57, respectively. 66 is a dry seal material made of rubber or the like that seals the gap between the double panel 59 and is provided on the outside of the vertical frame 53 and the horizontal frames 54 and 55, and 67 is made of synthetic resin for the same purpose. It is a dry sealing material provided on the extruded shape member 58 and the pressing edges 64 and 65.

  In FIG. 14, reference numeral 70 denotes an iron retaining bracket that is attached to the horizontal frame 54 with screws 71 and prevents the glass panel 59 from coming off in the event of a fire.

JP 2011-153519 A

  However, according to the conventional structure shown in FIG. 14 and FIG. 15, the pressing edges 65 and 64 made of synthetic resin extruded shapes having lower heat resistance compared to the metal extruded shapes have the glass panels 59 having the frame 50 and 52, respectively. Since the projections protrude inward from the inner surface in the in-plane direction by the widths indicated by W2 and W3, in the event of a fire, these ledges 64 and 65 are liable to be deformed or collapsed due to thermal effects. There is a problem that a gap is generated between 59 and the vertical frame 53 and the horizontal frame 54, or the glass panel 59 falls down, so that it is easy to spread from outside to inside or from outside to inside. There is a point.

  Further, it is necessary to attach the stopper metal fitting 70 after the glass panel 59 is mounted in the frame. However, when the width W1 (see FIG. 14) of the hooking part between the stopper metal fitting 70 and the glass panel 59 is increased, the screw stopper 71 is used. Since the attachment to the horizontal frame 54 becomes difficult and the pressing edge 65 is also enlarged, the width W1 of the hooking portion cannot be increased. For this reason, the width W1 of the hanging part between the stopper metal fitting 70 and the glass panel 59 must be reduced, and as a result, the glass panel 59 tends to fall down indoors, and the window portion is opened during a fire and spreads fire. There is a problem that it becomes easy to occur.

  In view of the above problems, the present invention makes it difficult to generate a gap between the glass panel and the window frame or the fence, and can securely hold the glass panel with the window frame or the fence even in the event of a fire. Therefore, an object of the present invention is to provide a window and a sash that are prevented from flowing hot air or flammable gas into the room and have an improved fire spread prevention function.

That is, since the indoor and outdoor surfaces of the glass panel 27 are held by the metal extruded profile (finding surface portion 25a and the pressing edge 28), the supporting force of the glass panel can be maintained for a long time even in the event of a fire. In addition, since the outside of the glass panel 27 is fixed by a pressing edge 28 made of a metal extruded profile, the width of the hanging portion of the glass panel 27 is restricted by the synthetic resin extruded profile 26 provided on the indoor side. Therefore, since the width of the hanging portion can be increased, the glass panel 27 can be firmly pressed and the glass panel 27 can be prevented from coming off.

  Further, since the heating foam material 29 is provided between the indoor side surface of the glass panel 27 and the finding surface portion 25a on the indoor side of the bowl, the heating foam material 29 expands in the event of a fire, so that the outdoor side of the glass panel 27 is expanded. Generation of a gap on the surface is also prevented. For this reason, hot air enters the indoor side from between the glass panel 27 and the flange 25a, or a flammable gas generated by heating of the spacer 33 and the sealing material 32 of the glass panel 27 enters the indoor side and the indoor side spreads. Can be prevented. In addition, since the glass panel 27 can be held on the gutter 25 by the expansion of the heating foam material 29 in the event of a fire, the configuration of the glass panel 27 can be maintained, and the occurrence of an opening due to the collapse of the glass panel 27 is prevented. The spread of fire due to the detachment of 27 is prevented.

  Moreover, since the heating foam material 30 was provided in the prospective surface part 25b which faces the end surface of the glass panel 27 of the gutter 25, when this heating foam material 30 expand | swells at the time of a fire, between the end surface of the glass panel 27 and the gutter 25 Is blocked. For this reason, the penetration | invasion to the indoor side of a hot air or combustible gas is prevented more reliably, and a fire spread prevention effect further improves. In addition, since the glass panel 27 is securely held by the flange 25 in the event of a fire, the spread of fire due to the detachment of the glass panel 27 is further reliably prevented.

  When the present invention is applied to a shoji, the glass panel 27 may be a single panel as described for the fixed window, and the outdoor pressing edge may be two or more of the four sides. Also, in the case of a shoji, a glass panel detachment fitting described for the fixed window may be provided in the bag. Further, the shoji may have a structure in which a single shoji is provided with a plurality of recumbent or downsides and a glass panel is divided.

  Although the present invention has been described above with reference to the embodiments, when the present invention is implemented, various changes and additions can be made to the constituent members and combinations thereof without departing from the spirit of the present invention.
