Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a heat insulating bridge material to connect double profile members inside or outside, or
The present invention relates to a structure in which one of heavy sections is made of a resin or a wooden material, and a non-combustible panel such as glass is mounted between interior and exterior materials to prevent the panel from falling due to a fire and to prevent fire spread.

[0002]

2. Description of the Related Art A heat insulation structure in which indoor and outdoor shape members of a shoji screen are made of aluminum alloy, and these shape members are connected by a bridge material made of rubber or resin, and a panel is incorporated between these inside and outside shape members. Shoji is known. The fitting having the shoji of such a heat insulating structure is effective not only for indoor and outdoor heat insulation but also for preventing dew condensation. The shoji with such a heat insulating structure supports one of the frame members movably through a door roller in the case of a sliding door (in the case of a sliding door), or rotatably supports a swing fulcrum (open door type). In the case), the other profile is supported by the one profile through a bridge material,
When heat is applied to the shoji in the event of a fire, the bridge material softens or burns, so the side not supported by the frame, the other shape, falls by its own weight, which causes the panel to fall as well. The flame may enter the room and spread the fire, or the flame in the room may go outside and spread the building or other room outside.

In order to prevent such spread of fire, Jikken Sho 6
In Japanese Patent Laid-Open No. 0-18536, a structure in which the indoor and outdoor profiles are joined by a bridge material is joined by a bolt covered with a heat insulating material so that the indoor and outdoor profiles are not separated even if the bridge material is softened or burned. An example of this has been disclosed.

[0004]

However, such a known structure has a problem of poor appearance because the heads of the bolts connecting the indoor and outdoor profiles can be seen from the outside or the inside of the room. Further, in order to support a heavy panel or shape member by bolt connection, it is necessary to use a considerably large number of bolts, resulting in an increase in the number of parts and an increase in the number of assembling steps. In addition, at the screw part at the tip of the bolt, the bolt is joined to one shape member by metal contact, and the head side is in contact with the hole of the other shape member through the thinly-insulated heat insulating material. There is a problem that the action is deteriorated. In addition, in such a known structure, it is not possible to use it for a shoji screen in which a metal shape member and a resin shape member are combined inside and outside in order to make a difference in the appearance inside and outside and to prevent dew condensation. There is a point.

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 internal and external profiles are joined by a bridge material. A first object of the present invention is to provide a fireproof structure for a fitting that does not damage the structure. A second object of the present invention is to provide a fireproof structure for a fitting that can be used even with a combination of a metal shaped material and a resin shaped material inside and outside.

[0006]

SUMMARY OF THE INVENTION In order to achieve the first object of the present invention, the interior and exterior profiles are connected by a heat insulating bridge material, and a non-combustible panel is provided between these interior and exterior profiles. Of the indoor and outdoor profiles, one of the profiles supported by the frame of the fitting has at least two of the four sides surrounding the incombustible panel, and has a panel locking piece at the tip thereof. It is characterized in that the preventive metal fitting is attached so as not to come into contact with the other shape member.

In order to achieve the second object, the present invention combines a metal shape member and a resin or wood shape member so that one is outside and the other is inside. A non-combustible panel is attached between the shape members, and a fall prevention metal fitting having a panel locking piece at the tip is attached to at least two sides of the four sides surrounding the non-combustible panel in the metal shaped material. And

[0008]

As described above, according to the present invention, in the shoji using the bridge material, even if the bridge material is softened or burned down, the panel is locked by the fall prevention metal fittings fixed to the frame supported by the frame. It is prevented from falling. When a resin or wooden shape member is used as one of the shape members, even if the resin or wooden shape member is softened or burned down, the panel is similarly locked by the fall prevention metal fittings to prevent the panel from falling.
