[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-layered structure in which another plate glass is arranged in parallel in the thickness direction of a fire-resistant plate glass containing a wire material such as a wire and a steel mesh formed by assembling the wire material. TECHNICAL FIELD The present invention relates to a laminated glass and an attachment structure of the laminated glass to a laminated glass attachment frame.

[0002]

2. Description of the Related Art Conventionally, as this type of double glazing, as shown in FIG. 5, a fireproof plate glass 5 such as a plate glass containing a wire and another plate glass 7 are arranged side by side via a spacer 6. There is one that is integrally formed by adhering to the above. The mounting structure of the double glazing to the double glazing mounting frame 1 of this type has a mounting concave groove portion M of the double glazing mounting frame 1. The edge of the double glazing is positioned inside, and the backup material 12 and the sealing material 13 are filled in the gap with the double glazing G in the groove M, and the double glazing G is formed by the frame 1 in the thickness direction thereof. It was attached in a state of being sandwiched between. Further, the conventional double glazing G of this kind is a general double glazing such as the prevention of dew condensation and the improvement of soundproofing / heat insulating effect, which can be realized by forming a closed space between the glass sheets 5 and 7. In addition to the features, by providing the wire-containing plate glass 5, for example, when a fire occurs, even if the other plate glass 7 collapses, the wire-containing plate glass 5
Is hard to be collapsed by being fixed by the wire rod 4, and maintains the blocking effect of the opening portion in which the multi-layer glass G is installed,
It also has a feature that it can be applied to a fireproof structure that can prevent the spread of flame and smoke through the opening.

[0003]

According to the above-mentioned conventional double glazing G, the respective glazings 5 and 7 are only integrated by adhering through the spacers 6, so that, for example, a fire may occur. If it occurs, the heat reduces the adhesive force of each plate glass 5, 7, and in the case of the mounting method of fixing to the double glazing mounting frame 1 only by the backup material 12 and the sealing material 13 as shown in the figure, Plate glass 7
Also, even if the spacer 6 falls off from the frame body 1 and the plate glass 5 with the wire remains in the frame body 1, there is a risk that a large gap is created between the glass plate 5 and the frame body 1 and the blocking of the opening cannot be achieved. . Therefore, in order to form the fireproof structure of the opening with the conventional double glazing G, the double glazing G
As shown in FIG. 6, the mounting structure of the multi-layer glass mounting frame 1 is configured to have a high strength and is not easily deformed, and the rigidity thereof is less deteriorated by heat. A non-combustible rope R is provided in a gap between the conventional multi-layer glass G having an edge fitted in M and the frame 1, and the multi-layered glass is provided by the elastic restoring force of the non-combustible rope R. The glass G must be sandwiched and fixed in the concave groove M. As described above, according to the conventional double glazing and the mounting structure thereof, in order to achieve the fireproof structure, it is troublesome to mount the double glazing and the frame body must be sturdy. Minutes, weight increases,
It has the drawback that it tends to have a rugged appearance and is inferior in handleability and aesthetics.

Therefore, in view of the above-mentioned drawbacks, an object of the present invention is to attach the light shielding device to a frame for mounting double glazing easily, and to attach it to a light frame which is excellent in handleability and aesthetics. Even so, the present invention is to provide a double glazing capable of achieving a fireproof structure and its mounting structure.

[0005]

In order to achieve this object, the characteristic constitution of the double glazing in the present invention is that a plurality of plate glasses arranged side by side in the thickness direction via spacers are provided in the thickness direction together with the spacers. A sandwiching member for integrally sandwiching from one side is provided, and the sandwiching member is provided with an attaching portion for attaching and fixing the sandwiching member in a state in which the sandwiching member is attached over the respective glass plates. .

The sandwiching member may be a side protector for double glazing, and the sandwiching member and the spacer may be integrally formed.

Further, the characteristic structure of the mounting structure of the double glazing according to the present invention is to mount a sandwiching member for integrally sandwiching a plurality of plate glasses arranged in parallel with each other from the outside in the thickness direction across the plate glasses. The sandwiching member is attached and fixed to a non-combustible or flame-retardant core material provided in the double-glazing attachment frame.

It should be noted that the double-glazing mounting frame is a building frame, or the double-glazing mounting frame is provided with a resin frame and the core material. The frame-making portion may be pressed by the holding member and the core material.

Further, a thermally expansive noncombustible material may be interposed between the holding member and the double-glazing mounting frame.

[0010]

According to the characteristic structure of the double glazing according to the present invention, since the sandwiching member is provided, the fireproof fire-resistant plate glass and the other plate glass are always fixed by sandwiching the edge portion by the sandwiching member, for example. Even if a fire or the like occurs and is exposed to heat, at least the portion sandwiched by the sandwiching members can be prevented from falling apart. Even if the glass is not sandwiched and fixed, it is possible to maintain the barrier property of the opening portion such as the window to which the double glazing is attached.
Therefore, it is possible to form a fireproof structure without providing a sandwiching portion for sandwiching and fixing the double glazing on the frame body.

Further, since the sandwiching member is provided with an attaching portion for attaching and fixing the sandwiching member to the double-glazing mounting frame, it is only necessary to attach and secure the mounting portion to the frame body. The laminated glass can be easily attached, and further, as described above, since it is not necessary to provide a sandwiching portion on the frame body, the multilayer glass is simply attached to the frame body having a strength sufficient to hold the attachment portion. Even if glass is attached, the double glazing does not fall apart or fall off due to fire, and even if the frame is not made of high-strength material as in the past, it has a sufficient fireproof structure. As a result, it is possible to use a frame body that is slim, lightweight, and has a beautiful appearance.

The sandwiching member can also serve as a side protector for protecting the edge portion of the double glazing during transportation or storage of the double glazing while performing the above-mentioned action. Becomes

Furthermore, if the sandwiching member and the spacer are integrally formed, the number of parts can be reduced and the cost can be reduced.

Further, according to the characteristic structure of the mounting structure for a double-glazing unit according to the present invention, a sandwiching member for integrally sandwiching a plurality of juxtaposed panes together with the spacer from the outside in the thickness direction is provided in each of the above panes. Attached over, since the sandwiching member is attached and fixed to the non-combustible or flame-retardant core material provided in the double glazing frame, for example, even if a fire occurs, the double glazing, It is supported in a state of being sandwiched integrally by a sandwiching member that is attached and fixed to the core member, and it is possible to prevent it from falling from the frame body,
Other than the core material of the frame body, it is possible to form a fireproof structure even if it is made of a material that burns by a fire, and as in the conventional case, it is constructed with a strength-oriented approach that does not burn down in a fire. It is possible to form a frame body having added design characteristics as compared with the mounting structure of double glazing.

When the frame for mounting double glazing is a building frame, the double glazing will not burn down unless the building itself is destroyed by a fire, and the double glazing can be mounted more reliably. It becomes possible to make it high.

The multi-layer glass mounting frame body comprises a resin frame portion and the core material, and the resin frame portion is sandwiched between the sandwiching member and the core material. For example, the sandwiching member that supports the edge of the multi-layer glass and the frame body are firmly fixed to improve the integration, and the good workability of the resin makes it possible to improve the design and reduce the manufacturing cost. Moreover, even when a fire occurs, at least the portion of the resin frame portion that is sandwiched between the sandwiching member and the core material is in a state in which it is unlikely to be affected by oxidative combustion from the surroundings, so Along with this, it is possible to prevent a gap through which smoke or flame passes between the holding member and the core material.

Furthermore, if a thermally expansive non-combustible material is interposed between the sandwiching member and the double-glazing mounting frame, the non-combustible material will generate heat when a fire occurs. By receiving and expanding, it is possible to make stronger contact with the sandwiching member and the frame body, and to locate smoke and flames without a gap between them.

[0018]

Therefore, according to the double glazing and the mounting structure thereof according to the present invention, the double glazing can be easily mounted on the double glazing mounting frame, the mounting work efficiency is improved, and the handling is improved. Even if it is attached to a light frame that excels in aesthetics and aesthetics, it is possible to configure a fireproof structure and improve the handling, aesthetics and functionality including the frame. It has become possible.
