Description

In the present invention, a glazing channel made of synthetic resin for fitting the glass panel into the glass fitting groove of the sash is provided in a state of being outerly fitted to the peripheral edge of the glass panel made of multilayer glass, and among the glazing channels, glass. The lower glazing channel that fits outside the bottom of the panel has a substantially U-shaped cross section from a pair of side wall portions having portions that are in close contact with both side surfaces of the glass panel and a bottom wall portion with respect to the bottom surface of the glass panel. The present invention relates to a sash mounting portion structure of a glass panel, a glazing channel for a glass panel, and a method of forming a sash mounting portion structure of a glass panel.

Conventionally, in the sash mounting portion structure of the glass panel, when the glass panel made of double glazing is mounted on the sash, a pair of sealing materials made of soft synthetic resin called glazing beat are brought into contact with each of both sides of the glass panel to sash. Some are attached so as to intervene between the sash and the glass panel to maintain the watertightness between the sash and the glass panel.
The glass panel is supported by a setting block, and a channel provided with a drainage groove is interposed between the setting block and the lower end of the glass panel (see, for example, Patent Document 1).
In order to form the above sash mounting structure by construction, there is a drawback that the work of assembling many of these parts at the construction site is complicated and requires a lot of labor and time.
Therefore, in order to easily attach the glass panel to the sash, a pair of side wall portions and a bottom wall portion integrally formed in a substantially U-shaped cross section are configured to be externally fitted so as to wrap the peripheral edge portion of the glass panel. Glazing channels are being considered.
Then, in order to integrate the pair of side wall portions and the bottom wall portion so that the glass panel fitted in the glazing channel is not easily attached to the sash, the pair of glazing channels is not detached from the glass panel. It is necessary to secure the strength of the bottom wall portion connecting the side wall portions of the glass by increasing the thickness to a certain level or more depending on the material.
At the same time, according to the fire prevention regulations required for fire doors for buildings, the sliding down phenomenon of the lower end surface of the glass of the glass panel due to softening and melting of the glazing channel in a high temperature environment such as a fire must be 3 mm or less.
Therefore, it has been proposed to satisfy the above-mentioned fire prevention regulations by storing the heat-resistant member in the bottom wall portion (see, for example, Patent Document 2).
