Description of the Related Art According to Article 110, Paragraph 2 of the Building Standards Law Enforcement Ordinance, there are Class A fire doors and Class O fire doors as fire protection grades. According to Notification No. 1125, the fireproof heating temperature curve is 60 minutes for Class A fire doors and 20 for Class O fire doors.
It has passed the minute. There is a netted glass plate as a glass plate used for Class B fire doors, and the glass plate breaks during heating under the conditions for Class B fire doors, but since the metal net inside the netted glass plate is hardly broken, ,
The net prevents the glass plate from falling off and prevents the penetration of fire.

し垂れ下がってしまうことが知られている。However, when a wire-containing glass plate is heated under the conditions for a class A fire door, the heating time is long and the heating temperature is high, so that the glass plate is kept at a temperature exceeding the softening point of the glass for a long time, and the glass plate is It softens and sags and falls off. Further, it is known that even when a low expansion tempered glass plate is used, it does not crack under the heating conditions for a fire door of type A, but it softens and hangs down.

場合があった。The prevention of sagging of the glass plate can be realized by packing a non-combustible material around the glass.
There was a problem that this bite work takes time.
Also, due to the dimensional tolerance of the groove width of the glass plate and the sash, if the gap is too narrow to perform the crawling work, or if the gap is too wide to carry out the crawling work, heating is performed under the conditions for the Class A fire door. In some cases, it was not possible to prevent the glass plate from hanging down.

ならない。More specifically, one example of the bimetal sandwiching member having an approximately Ω-shaped cross section has a metal having a small thermal expansion coefficient on the inside and a metal having a large thermal expansion coefficient on the outside. The fins on both ends of the bifurcation are shaped to bulge outward, and the approximately Ω-shaped head of the bimetal sandwiching member cross section is substantially flat or slightly convex. When the sandwiching member made of the bimetal sandwiching member is thermally deformed, by pressing the end portion of the fireproof glass panel against the backup material, the fireproof glass panel and the sealing material are separated from each other so that the sealing performance is not deteriorated. The cross-sectional shape of the bimetal clamping member must be produced.

It is preferable to be present in terms of manufacturing cost. The fireproof glass panel is not particularly limited, but preferably a low expansion glass plate (for example, borosilicate glass plate), transparent crystallized glass or meshed glass is used.

ル製挟持部材でガラス板が摩擦力で押圧保持される。According to the present invention, the glass plate is pressed and held by frictional force against the frame body and the ridge of the sash by the noncombustible backup material at room temperature, and the temperature of the plate glass rises with the temperature of the bimetal holding member at the time of fire. However, the bimetal clamping member deforms in such a direction that the frame body and the ridge are pushed by the fins of the bimetal clamping member while pinching the peripheral edge of the plate glass more strongly, so that the bimetal clamping member is further made of the non-combustible material with respect to the frame body and the ridge. The glass plate is pressed and held by the sandwiching member by frictional force.

ときにガラス板は軟化するが、防火ガラスパネル材の上
辺または上辺と縦辺がサッシ枠に対して摩擦力で押圧保
持されているため、ガラス板は軟化して垂れ下がりはし
ない。For this reason, the glass plate softens when heated under the conditions of a class A fire door, but since the upper side or the upper side and the vertical side of the fireproof glass panel material are pressed and held by frictional force against the sash frame. , The glass plate softens and does not sag.

持する必要はない。In this way, it is possible to prevent the glass sheet from sagging due to the thermal deformation of the bimetal holding member having a cross section of approximately Ω, and to prevent the penetration of flame. Since the present invention prevents the glass plate from hanging down due to heat, it is not necessary to press and hold the lower side of the fireproof glass panel material against the sash frame by frictional force.

る。Further, even if the groove width of the sash is slightly different from the design size, it can be absorbed by the degree of deformation of the bimetal holding member, the glass plate can be firmly pressed and held by the sash frame, and the cutting work as in the prior art can be performed. Workability is improved because it is eliminated.

かち込み作業がなくなるため、作業性も向上する。Since the present invention is configured as described above, it has the following effects. According to the configuration of the present invention, at the time of fire, the upper side or the upper side and the vertical side of the glass panel are fixed to the sash frame by the frictional force of the bimetal holding member, so that even when heated under the condition of a class A fire door. The glass plate softens but does not sag.
For this reason, a glass plate can be used for the class A fire door, and the transparency of the glass plate is used to effectively improve the safety such as the discovery of a fire and the discovery of an evacuation route. Moreover,
The method of packing the non-combustible material around the glass plate to prevent the glass plate from hanging down due to heat is that it takes a long time to perform the pushing operation, it cannot be done, or it is too loose to prevent the dropping. Although there were many problems, this problem was solved in the present invention, even if the groove width of the sash is slightly different from the design size, it can be adjusted by tightening the screw,
Workability is also improved because there is no need to push in.
