DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for connecting double indoor and outdoor profiles by means of a heat-insulating bridge,
The present invention relates to a structure in which one of heavy profile members is made of a resin or a wooden material and a glass panel is mounted between exterior members of a room to prevent the panel from dropping due to a fire and to prevent the spread of fire.

[0002]

2. Description of the Related Art A heat insulating structure in which indoor and outdoor profiles of a shoji are made of an aluminum alloy, these profiles are joined by a rubber or resin bridge material, and a panel is incorporated between the interior and exterior profiles. No shoji is known. The fittings having such a heat-insulating screen are effective not only for heat insulation inside and outside the room but also for dew condensation prevention. A shoji having such a heat insulating structure is configured such that one of the profile members is movably supported by a frame via a door roller (in the case of a sliding door), or the other is rotatably supported about a pivot point (a swing door). Case), the other profile is supported by said one profile via a bridge,
When heat is applied to the shoji during a fire, the bridge material softens or burns, so that the other side material not supported by the frame falls by its own weight, which causes the panel to fall, and the outside The flame invades the room and spreads the fire, or the flame in the room goes out and spreads the building or another room.

In order to prevent such spread of fire, Japanese Utility Model Publication No.
In Japanese Patent Publication No. 0-18536, indoor and outdoor profiles joined by a bridge material are joined by bolts covered with a heat insulating material, so that even if the bridge material softens or burns, the interior and exterior profiles are not separated from each other. Examples are disclosed.

[0004]

However, such a known structure has a problem that its appearance is poor because the heads of the bolts connecting the indoor and outdoor profiles are visible from the outside or the inside of the room. Further, in order to support a heavy panel or a shaped member by bolt connection, a considerably large number of bolts must be used, resulting in a problem that the number of parts increases and the number of assembly steps increases. In addition, the bolt is connected to one of the profiles by metal contact at the threaded portion at the tip of the bolt, and the head side is in contact with the hole of the other profile through a thinly coated heat insulating material. There is a problem that the action is deteriorated. In addition, such a known structure cannot be applied to a shoji made of a combination of a metal profile and a resin profile inside and outside in order to give a difference in the appearance inside and outside the room and to prevent dew condensation. There is a point.

[0005] In view of the above problems, the present invention has a good appearance, can reduce the number of parts and man-hours, and has a heat insulating effect when applied to a fitting in which inner and outer profiles are joined by a bridge material. A first object is to provide a fire prevention structure for a fitting having a structure that does not impair. It is a second object of the present invention to provide a fire prevention structure for a fitting that can employ a combination of a metal profile and a resin profile inside and outside.

[0006]

According to the present invention, in order to achieve the first object, as described in claim 1, indoor and outdoor metal profiles are joined by a heat-insulating bridge material. A glass panel is mounted between the inner and outer profiles, and the outdoor profile is supported by a frame of a fitting and surrounds the glass panel.
At least two of the sides are provided with a fall prevention metal fitting having a panel locking piece on the indoor side, to the outdoor shape material on at least two sides.

According to the present invention, in order to achieve the second object, an outdoor metal section and an indoor resin or wood section are combined with each other, as described in claim 2. A glass panel is mounted between the profiled members, and a fall prevention fitting having a panel locking piece on the indoor side is attached to at least two of the four sided metal profiled members surrounding the glass panel. It is characterized by.

[0008]

According to the present invention, as described above,
The outdoor profile is supported by the frame of the fittings, and the outdoor profile is fitted with a fall prevention bracket having a panel locking piece on the indoor side, so the outdoor profile itself falls. In a sash that is difficult to perform and the shape members inside and outside of the room are joined by the bridge material, even if the shape material inside the room is detached due to softening or burning out of the bridge material, at least two sides of the panel are not covered by the fall prevention metal fittings. Since the panel is locked by the panel locking pieces, the panel is prevented from falling to the outdoor side. Also, unlike the case of bolts, the fall prevention fitting can adopt a mounting structure invisible from the outside or inside of the room by bonding, fitting, locking, etc., and does not impair the appearance. Also,
The number of parts and the number of assembling steps are reduced as compared with the case where the indoor and outdoor profiles are joined by bolts. According to the second aspect, even if the indoor resin-made or wooden profile combined with the outdoor-side metal profile is burned down, the panel locking piece of the fall prevention fitting attached to the metal profile is burned out. At least two sides of the panel are locked by
The panel can be prevented from falling to the outdoor side.
