Description

  The present invention relates to a translucent panel for road used by being arranged along a road.

As such a translucent panel for roads, for example, there is a sound insulation panel having translucency for preventing noise from the road side from leaking to the private side.
In the case of sound insulation panels, sound insulation is also required in addition to translucency. Conventionally, those made of polycarbonate plate materials are known to satisfy these requirements, and they are actually used on expressways and general roads. (For example, refer to Patent Document 1).

JP-A-4-302608

  By the way, although polycarbonate is self-extinguishing, it dissolves when exposed to high temperatures. For example, when a vehicle fire occurs near a translucent panel, it melts and falls to the private side. There is a fear. Naturally, the melted material is hot, and it is very dangerous if it falls to the private side. If there is a combustible material at the point of fall, there is a possibility of a secondary fire.

  The present invention focuses on such conventional problems, and its purpose is to avoid damage to the private side as much as possible even when exposed to high temperatures due to the occurrence of a vehicle fire or the like. It is in providing the translucent panel for roads.

  1st characteristic structure of this invention is a translucent panel for roads arrange | positioned and used along a road, Comprising: The said panel is laminated glass which bonded the plate glass and the net plate glass through the intermediate film The plate glass is disposed on the road side and the mesh plate glass is disposed on the private side.

According to the 1st characteristic structure of this invention, the translucent panel for roads used by arrange | positioning along a road is formed with the laminated glass which bonded the plate glass and the net plate glass through the intermediate film. Therefore, not only the translucency required for the translucent panel for roads but also the sound insulating property necessary for the sound insulating panels for roads is provided.
And, since the translucent panel is made of laminated glass, and the plate glass is arranged on the road side and the mesh plate glass is arranged on the private side, the road side plate glass is damaged by impact, for example. In this case, scattering of the fragments is suppressed by the intermediate film, and at least the fragments of the plate glass are prevented from scattering to the private side. When the impact is so great that even the meshed glass is broken, the scattering of the fragments to the private side is suppressed by the adhesiveness of the intermediate film and the mesh of the meshed glass.
Furthermore, for example, when exposed to high temperatures due to the occurrence of a vehicle fire, there is little risk of melting and falling to the private side like conventional polycarbonate, and an optimal translucent panel for road use is provided. be able to.

  The 2nd characteristic structure of this invention exists in the place where the plate glass used for the said road side is a tempered plate glass.

  According to the 2nd characteristic structure of this invention, since the plate glass used for the road side is a tempered plate glass, it is excellent in impact resistance from the road side, and there is no possibility that it may be damaged or scattered by a small impact.

  A third characteristic configuration of the present invention is that the meshed plate glass is a meshed plate glass in which metal wires are arranged and embedded in a vertical, horizontal, or diagonal lattice shape.

  According to the third characteristic configuration of the present invention, the mesh-containing plate glass is a mesh-containing plate glass in which metal wires are arranged in a vertical, horizontal, or diagonal lattice shape, and as described above, When the meshed glass is broken, the vertical, horizontal, or diagonal grid-like metal wire rods suppress the scattering of fragments.

  According to a fourth characteristic configuration of the present invention, the meshed plate glass is a meshed plate glass in which metal wire rods are embedded in a vertical or horizontal direction.

  According to the fourth characteristic configuration of the present invention, the meshed plate glass is a meshed plate glass in which metal wires are arranged in a vertical or horizontal direction. A wire will suppress scattering of fragments.

  A fifth characteristic configuration of the present invention is that the panel is used as a sound insulation wall for a road.

  According to the fifth characteristic configuration of the present invention, since the panel is used as a sound insulation wall for roads, as described above, in addition to translucency and sound insulation, the panel also has impact resistance, and further, at high temperatures. The wall which can maintain the very excellent sound insulation performance for roads can be provided.

  A sixth characteristic configuration of the present invention is that the panel is used as a protective fence for roads.

  According to the sixth characteristic configuration of the present invention, since the panel is used as a protective fence for roads, the panel has translucency, sound insulation and impact resistance, and further has a remarkable characteristic under high temperature. The fence which can maintain the protection performance for the road which has excellent can be provided.

Embodiments of a translucent panel for road according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the translucent panel 1 for a road is fitted into a rectangular frame F made of an extruded product of aluminum, for example, and attached to a panel column outside the figure. It is arranged along the side and used as a sound insulation wall for roads, or used as a protective fence for roads or a protective fence for parking lots.
As shown in FIG. 2, the translucent panel 1 includes a transparent single plate float plate glass 2, preferably a transparent net plate glass 4 in which a reinforced plate glass 2 and a metal net 3 are embedded via an intermediate film 5. It is made of laminated glass laminated together.

In the embodiment shown in FIGS. 1 and 2, the metal net 3 is formed in a grid pattern vertically and horizontally by using iron wire rods 3 a arranged in the vertical direction and iron wire rods 3 b arranged in the horizontal direction. ing. However, the metal net 3 may be formed in a lattice shape in an oblique direction, and is not necessarily in a lattice shape. For example, the wire 3a may be embedded side by side only in the vertical direction, The wires 3b can be embedded side by side only in the horizontal direction or can be embedded side by side only in the oblique direction.
As the intermediate film 5, a tough and transparent adhesive film, for example, a resin film such as PVB (polyvinyl butyral) or EVA (ethylene vinyl acetate copolymer) is used. The translucent panel 1 is formed by being sandwiched between the glass plates 4 and bonded by thermocompression bonding.
And this translucent panel 1 arrange | positions the plate glass 2 on the road side, arrange | positions the plate glass 4 with a net | network on the private side, and is used as a sound insulation wall for roads, or a protection fence.

Therefore, when the road-side plate glass 2 is damaged due to an impact, or when the private-side net-containing plate glass 4 is damaged in addition to the road-side plate glass 2, the scattering of fragments is caused by the intermediate film 5 and the net-containing glass. 4 is suppressed by the net 3 and scattering and falling to the private side are prevented.
In addition, when a vehicle fire occurs and the translucent panel 1 is exposed to a high temperature, there is little possibility of melting like conventional polycarbonate and falling to the private side.

[Another embodiment]
(1) In the previous embodiment, although the example which formed the translucent panel 1 with the laminated glass which consists of the plate glass 2 and the net-containing plate glass 4 was shown, the plate glass 2 arrange | positioned at the road side is made into a net-containing plate glass. You can also.

(2) In the previous embodiment, the example in which the translucent panel 1 is fitted into the frame body F has been shown. However, the use mode of the translucent panel 1 is not particularly limited. For example, the frame body Without using F, the translucent panel 1 can be arranged as it is on the side of the road.
