Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing structure for meshed glass in a curtain wall for fixing meshed glass, which is a combination of meshed glass and glass having a reflection effect such as reflective glass or transparent glass.

[0002]

[Prior Art]

 The meshed laminated glass in the curtain wall is a glass having a reflection effect on the outside of the meshed glass, and such glass is joined to the metal frame material by a sealing material, and the edge of the glass is a metal frame. The entire surface is fixed so that it is not covered with wood. Therefore, since the metal frame material cannot be seen from the outside, a clean glass surface can be obtained.

[0003]

[Problems to be solved by the device]

 Conventional meshed laminated glass is fixed to the metal frame material by a sealing material as described above, but if the sealing material that joins the glass and the metal frame material is destroyed by fire in the event of a fire, the glass Could fall off and the flame could penetrate to the outside.

The present invention has been made to solve the above-mentioned problems. Even if the sealing material burns out in the event of a fire, it is possible to prevent the penetration of the flame to the outside, and it is possible to prevent the inside and outside of the interior from being damaged. The purpose is to obtain a fixed structure of laminated glass that does not impair the design.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the fixing structure of the net-like laminated glass according to the present invention is to fix the net-like laminated glass which is a combination of the net-like glass and the glass having a reflection effect. The end portion of the adhesive layer material that joins the both glasses is shorter than the end surface of the mesh-filled glass, and its thickness is made thicker than the plate thickness of the U-shaped cross-section metal blocking material to form a gap in the joining portion of the both glasses, Insert one end of the U-shape of the metal blocking material into the same gap, and bring the other end into contact with the parallel part of the metal frame material, and the outside of the other end from the inside of the metal frame material to the metal frame material. It is characterized in that an L-shaped cross-section fastening member screwed to the protrusion is pressed and fixed so as not to move to the outside, and the outside of the fastening member is covered with a sealing material.

[0006]

[Action]

 Since the fixing structure of the wire-laid laminated glass according to the present invention is configured as described above, even if the seal material is burnt out in the event of a fire, the metal blocking material fixed to the metal frame material by the stopper material is used. It securely holds the wire-cored glass and prevents it from falling off, which prevents the penetration of the flame to the outside. In addition, the metal blocking material has one end inserted into the gap between the meshed glass and the glass having a reflection effect, is not exposed to the outside, and is not visible from the outside, so it is neat. Since the glass surface can be maintained and the stopper is covered with the sealant, a good design can be maintained.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in FIG. 1, the meshed laminated glass is formed by bonding glass 2 having a reflection effect such as reflective glass or transparent glass to the outside of meshed glass 1 through an adhesive layer material 3. By making the end portion 9 of the adhesive layer material 3 shorter than the end surface 8 of the mesh-containing glass 1 and making the thickness thereof thicker than the plate thickness of the metal blocking material 5 described later, the metal at the joint portion of the both glasses 1 and 2 is made. The gap 4 for inserting the one end 12A of the blocking member 5 is formed. The thickness of the adhesive layer material 3 is preferably such that an iron plate with a thickness of 0.8 mm or more, which is recognized as a type-II fire door of the Building Standard Act, Article 110, enters the gap 4, but less than that. However, it is possible when the test is confirmed.

The metal blocking member 5 has a U-shaped cross section, and has one end 12A inserted into the gap 4 and the other end 12B abutting against the parallel portion 10A of the metal frame member 6. In addition, the metal frame member 6 includes right-angled surfaces 11A and 11B that are perpendicular to the parallel portions 10A and 10B parallel to the surface 15 on the indoor side A of the meshed glass 1 and parallel surfaces 10A and 10B to the surface 15 of the meshed glass 1. It has projecting portions 16A and 16B projecting in a direction perpendicular to the.

One end 12A of the metal blocking member 5 is inserted into the gap 4, the other end 12B of the metal blocking member 5 is brought into contact with the parallel portion 10A of the metal frame member 6, and the outer side thereof is screwed to the projecting portion 16A from the indoor side A. It is fixed so as not to move to the outside by being pressed by the stopper 13 having an L-shaped cross section. The receiving members 14A and 14B are mounted between the stopper member 13 and the surface 15 of the wire-reinforced glass 1 and between the surface 15 and the flat portion 10B of the metal frame member 6, respectively. The meshed laminated glass is fixed from the inside A of the chamber by mounting the sealing material 7B so as to cover the inside.

On the other hand, from the outer side B, the meshed laminated glass is fixed by mounting the receiving material 14C and the sealing material 7A between the protruding portion 16B and the metal blocking material 5 and the end surface of the glass 2 having the reflection effect. To do.

According to the above configuration, since the laminated glass having a mesh structure is fixed and held to the metal frame material 6 by the metal blocking material 5, even if the seal materials 7A and 7B are burned out by a fire, the metal blocking material Since 5 holds the meshed laminated glass and can prevent the glass from falling off, it is possible to prevent penetration of the flame to the outside.

Further, since the one end 12A of the metal blocking member 5 is inserted into the gap 4 between the meshed glass 1 and the glass 2 having the reflection effect, the metal blocking member 5 should not be seen from the outside. Moreover, by finishing the metal blocking material 5 in a dark color such as black, a good design can be maintained even with transparent glass.

Further, since the stopper member 13 is covered with the seal member 7B even on the indoor side, there is no fear of impairing a good design.

In the above embodiment, the metal frame member 6 has the parallel portion 10A and the protruding portion 16B in the direction perpendicular to the surface 15 of the reticulated glass 1. However, as shown in FIG. The same can be applied to the structure having the symmetrical metal frame member 6A without the protruding portion 16B. In this case, the sealing member 7A and the receiving member 14C are provided with the opposing metal blocking member 5 and the reflection effect. The glass 2 is mounted between the end faces of the glass 2.

[Effect of the device]

 As described above, according to the wire-bonded laminated glass fixing structure of the present invention, it is possible to prevent the penetration of the flame to the outside even if the sealing material is burnt out in the event of a fire, and to the outside. Since it is possible to eliminate the exposure of the metal blocking material and the stopper on the indoor side, it is possible to maintain a clean glass surface and maintain a good design.
