  However, although the decorative lattice mounting apparatus disclosed in Patent Document 1 and Patent Document 2 are not particularly defective in terms of function, improvement of the following problems is desired.

  In other words, when a fire occurs in the vicinity of a building, it is necessary to prevent the flame from the outside from entering the room through windows and doors to avoid the spread of fire. Conversely, a fire occurs in the room of the building. In this case, it is necessary to prevent the indoor flame from blowing out from the window or door to prevent it from spreading to nearby buildings, and the window or door needs to exhibit the function of a fire door.

  However, the windows and doors shown in Patent Document 1 and Patent Document 2 are used when the shoji side fence and decorative lattice are machined when a fire occurs in a nearby adjacent building, or when a fire occurs in the room of your own building. Since it is firmly fixed by the attachment device of the type, it is heated by the flame while it is fixed as it is.

  For this reason, if one or both of the fence and the decorative lattice are deformed at a high temperature, cracks and gaps occur in the deformed part on the shoji side, and if a fire occurs outside, the flames from these cracks and gaps are self-building. If a fire breaks out in the building of your own building and fires in your own building, a flame may spur out from the cracks or gaps and spread to surrounding buildings.

  Accordingly, the object of the present invention is to prevent the occurrence of cracks and gaps due to deformation on the shoji side even when a fire breaks out and the fire doors such as windows and doors are exposed to high temperatures, thereby preventing the intrusion and ejection of flames. An object of the present invention is to provide a device for attaching a decorative lattice in a fire door such as a window or a door.

In order to achieve the above object, one of the means of the present invention is a decoration comprising a shoji made of a metallic saddle, glass held in the saddle, and a metal cylinder facing the shoji. In a fire door comprising a window and a door provided with a lattice and a metal attachment member for attaching the decorative lattice to the saddle member,
A cap made of synthetic resin is press-fitted into an end of the cylindrical body, and the cap is attached to the saddle member via the attachment member.

Similarly, the other means includes a metal frame attached to the opening of the frame, a shoji made of glass held in the frame, and a decorative lattice made of a metal cylinder facing the shoji. A sash window comprising a metal attachment member for attaching the decorative lattice to the saddle member,
A cap made of synthetic resin is press-fitted into the end of the cylinder, and a notch groove cut in the axial direction is formed in the end of the cylinder,
A head portion that abuts the cap on the end opening end surface of the cylindrical body, a cylindrical portion that extends in the axial direction from the head portion and is press-fitted into the cylindrical body, and outwardly on a head side end portion of the cylindrical portion It is composed of a projecting portion that bulges or projects toward and fits into the notch groove, and a locking hole that is bored in the projecting portion,
The mounting member is constituted by a bolt or a screw inserted into the locking hole and the notch groove from the outer surface side of the saddle member and fitted to the protruding portion.

According to the decoration grid mounting device of the present invention, when the fire door comprising windows and doors is exposed to a high temperature by a flame caused by a fire and the shoji side saddle or the decoration lattice side cylinder is heated, the cap also At the same time, the cap, which has a lower melting point than that of the eaves or cylinder, melts away prior to the shoji and decorative lattice.
As a result, the coupling between the shoji-side material and the decorative lattice-side cylinder is eliminated, and the decorative lattice falls under its own weight. And the occurrence of gaps can be prevented.
For this reason, it is possible to prevent a flame at the time of a fire from entering or ejecting from a fire door such as a window or a door, to prevent the spread of fire to the vicinity of the fire site, and to improve the fire prevention function.
