Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a fireproof glass panel support structure for use in fireproof areas.

[0002]

2. 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.

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.

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.

There is also a structure using a bimetal piece as a fireproof glass fitting structure having a pressure system that works on the edge region of a glass plate in the event of a fire (JP-A-61-1438).
4) It merely exemplifies that the bimetal piece is used, and it cannot be said that the interlocking action with the guide device when the bimetal piece is thermally expanded is not so good, and the bimetal piece is actually the guide device. It slipped inside and didn't work well.

[0006]

DISCLOSURE OF THE INVENTION It is an object of the present invention to manufacture a class A fire door without regard to some dimensional tolerances of the groove widths of the glass plate and the sash, and to put an incombustible material around the glass plate. Another object of the present invention is to reliably and efficiently realize pressure-holding of a glass plate with a pressure capable of holding it by another means, that is, a bimetal holding member, without resorting to a packing operation.

[0007]

According to the present invention, the periphery of a fireproof glass panel is sandwiched and supported by a frame and a ridge from both sides via a backup material, and the outside of the backup material with respect to the frame and the ridge is sealed by a sealing material. A sealed fireproof glass panel supporting structure, wherein at least a part of a peripheral edge of the fireproof glass panel on the end face side of the glass plate with respect to the backup material has a substantially Ω-shaped cross section, and both ends of the Ω-shaped opening side. The bimetal sandwiching member having fins is sandwiched in its outer direction, and when heat is applied to the fireproof glass panel support structure, the bimetal sandwiching member sandwiches the peripheral edge of the fireproof glass panel, The fireproof glass panel is held by pressing the frame body and the ridge with fins at both ends of the sandwiching member. It is a fireproof glass panel support structure.

Further, according to the present invention, the periphery of the fireproof glass panel is supported by being sandwiched from both sides by a frame having a U-shaped cross section with a backup material interposed therebetween, and the outside of the backup material with respect to the frame. A fireproof glass panel support structure sealed with a sealing material, wherein at least a part of a peripheral edge of the fireproof glass panel closer to an end surface of the glass plate than the backup material has a cross section of substantially Ω shape, and the Ω opening. A bimetal sandwiching member having fins in the outer direction is sandwiched at both ends of the side, and when heat is applied to the fireproof glass panel support structure, the bimetal sandwiching member sandwiches the periphery of the fireproof glass panel. The fireproof glass panel is held by pressing the frame body and the ridge with fins at both ends of the bimetal holding member. It is a fireproof glass panel support structure to be considered.

The cross section of the bimetal sandwiching member has a substantially Ω-shaped cross section, and has fins in the outward direction at both ends of the Ω-shaped opening, and also has a substantially U-shaped cross section. Also, a U-shaped opening having fins in the outer direction at both ends thereof, or a U-shaped cross section having fins in the outer direction at both ends of the U-shaped opening can be employed.

Preferably, at least a part of the peripheral edge of the fireproof glass panel on the glass plate end surface side of the backup material is sandwiched by a bimetal sandwiching member having a substantially Ω-shaped cross section through a cushioning material.

The bimetal holding member has a length of 10 to 10
Those having a thickness of 0 mm may be mounted with a bimetal holding member having a mounting interval of 50 to 500 mm. Alternatively, a bimetal holding member having a length substantially corresponding to the length of one side of the fireproof glass panel may be used.

The metal used for the bimetal holding member preferably has a high softening point. Further, this bimetal clamping member is not in contact with the frame and the ridge at room temperature or is only slightly touched, and when the fireproof glass panel (plate glass or the like) is heated, the temperature of the bimetal clamping member also rises. , The bimetal sandwiching member is deformed to sandwich the periphery of the fireproof glass panel, while holding the fireproof glass panel by strongly pressing the frame body and the ridge with fins at both ends of the cross section of the bimetal sandwiching member, the object of the present invention is to In order to achieve this, the metal forming the bimetal holding member is selected and the shape of the bimetal holding member is determined.

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.

The combination of metals forming the bimetal holding member and the shape of the bimetal holding member are determined in consideration of the temperature environment in which the fireproof glass panel is placed during a fire.

A bimetal sandwiching member is sandwiched between the upper side or the upper and vertical sides, which are sides supporting the fireproof glass panel, and a bimetal sandwiching member is not sandwiched around the lower side. 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.

The frame body may connect the fireproof glass panel and the supporting member on the side of the building frame, or may connect two fireproof glass panels. Further, as the non-combustible backup material, a ceramic fiber, preferably a felt made of aluminosilicate fiber, as the sealing material a flame-retardant seal, preferably a flame-retardant silicon sealant,
As the cushioning material, a sheet made of aluminosilicate fiber is preferable, and as the frame body and the ridge, those having a high softening point are preferable.
Iron materials, stainless steel materials, etc. are used.

[0017]

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.

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.

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.

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.

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.
