2. Description of the Related Art Heretofore, a sheet glass body holding member 26 of this kind has conventionally been used.
In particular, in consideration of elastically supporting the glass sheet body 6 on the glass sheet supporting frame 1, a synthetic resin such as a vinyl chloride or elastomer resin having a Shore A hardness of about 60 to 75 degrees is used. In some cases, the portion 25a was formed, and the color was one color such as white, black, gray, or brown (see FIG. 21). In addition, as a conventional sheet glass body, there has been one in which the above-mentioned conventional sheet glass body holding member is fitted to a peripheral portion.

[0003]

According to the above-mentioned conventional sheet glass body holding member and the sheet glass body, the soft holding portion interposed between the sheet glass body supporting frame and the sheet glass body main body can be used in the event of a fire. It is easy to burn, as a result, the soft holding portion disappears, and a gap that is a weak point in fire prevention between the glass body supporting frame and the glass body body easily occurs, and the glass body is not sufficiently held. There was a problem that was easy to become.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a glass sheet holding member and a glass sheet body in which the supporting performance of the glass sheet body during a fire is hardly reduced.

[0005]

[Means for Solving the Problems] The constitution of the first aspect of the present invention is, as exemplified in FIGS. 1 to 20, a member main body having a concave groove portion 8 capable of receiving the peripheral portion of the sheet glass main body 6. 6a is formed so as to be freely fitted into the frame 1 for supporting a glass body, and between the member body 6a and the front and back surfaces of the glass body 6 in a state where the glass body 6 is received in the concave groove portion 8. The holding part 6b interposed elastically deformable
In the flat glass body holding member provided integrally with the member main body 6a, at least the holding portion 6b of the member main body 6a and the holding portion 6b is formed of a flame-retardant material.

[0006] The characteristic structure of the invention of claim 2 is shown in Figs.
As shown in the example, the holding portion 6b is formed of a soft member, and the member main body 6a is formed of a member harder than the holding portion 6b.

[0007] The characteristic structure of the invention of claim 3 is shown in FIG.
0, the member body 6a or the holding portion 6b, or the member body 6a and the holding portion 6b
Is provided with an identification means P for enabling identification from a conventional product.

[0008] The characteristic structure of the invention of claim 4 is shown in FIG.
As exemplified in FIG. 0, the identification means P is located in an uneven pattern.

A feature of the invention according to claim 5 is that the identification means P is a color pattern.

A feature of the invention according to claim 6 is that the identification means P is a combination of a concavo-convex pattern and a color pattern.

A feature of the invention according to claim 7 is that the main material of the flame-retardant material is a vinyl chloride polymer or a thermoplastic elastomer, and a flame retardant is added as an auxiliary material and a plasticizer is added. The filler is also provided with flame retardancy.

An eighth feature of the present invention is shown in FIGS.

The elastic extension locking portion 15 inclines the facing portion 15a facing both edges of the fitting groove 3 so that the distal end in the projecting direction is closer to the sash 1 than the base end in the projecting direction. The sash 1 is formed so as to be easily used. According to the elastic extension locking portion 15, even if there is a difference in the degree of entry of the multilayer glass holding member into the fitting groove 3, the difference is absorbed within the elastic range as shown in FIGS. In addition, it is easy to prevent a gap from being formed between the facing portion 15a and the sash 1. Therefore, even when the multi-layer glass body 6 and the sash 1 have a dimensional tolerance along the surface direction of the multi-layer glass body 6, the sash 1 and the multi-layer glass H are fitted to each other, and the aesthetics in the mounted state of the two. , And infiltration of rainwater into the sash 1 can be suppressed.

Incidentally, the double glass holding member 7 is a single long body before being mounted on the double glass body 6, and one of the mounting methods to the double glass body 6 is as follows. The multilayer glass holding member 7 is cut into a predetermined size corresponding to the length dimension of each side of the multilayer glass main body 6 and an edge portion thereof has a cut angle of 45 degrees.
(See FIG. 5) by fitting into the periphery of the multilayer glass body 6 through the opening of the concave groove 8 and abutting the edges of the holding members 7 together. The holding members need not be bonded to each other, but may be bonded using an adhesive or a solvent.

It has been confirmed that the double-glazed glass H thus formed can be used, for example, as a type B fire door in a fire test based on Ministry of Construction Notification No. 1125.
