Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a translucent sound insulating wall installed along a road or a railway.

[0002]

2. Description of the Related Art Conventionally, sound insulation walls have been installed along roads and railroads for the purpose of preventing vehicle noise and projections. Some of such sound insulation walls are formed from an opaque plate such as metal, but those formed from an opaque plate are shielded from surrounding scenery by the opaque plate. Such translucent sound insulation walls have been installed along roads and railways.

[0003]

For example, as shown in FIG. 7, a conventional light-transmitting sound-insulating wall is generally provided with an angle material or the like on the periphery of a light-transmitting plate a made of a synthetic resin such as polycarbonate having excellent impact resistance. A frame member b made of a rectangular steel pipe or an extruded aluminum material is attached to form a panel body c that can withstand a wind load or an impact load, and the left and right sides of the panel body c are erected at predetermined intervals. Is inserted into and supported by the opposite grooves of the column d made of H-shaped steel, and is fixed to the column d so that the panel body c does not fall off the column d due to a collision of an accident vehicle or the like and fall off the road. The fall prevention wire is inserted into the frame member b.

[0004] However, the light-transmitting sound insulation wall as described above is
Since the frame member b is attached to the periphery of the light transmitting plate a,
There is a problem that the surrounding landscape is blocked by the frame material b. Therefore, the frame member b is eliminated, and the thickness of the light transmitting plate a is increased to use a so-called frameless light transmitting plate a which is made to withstand the wind load and the impact load by the strength of the light transmitting plate a itself. In some cases, a light-transmitting sound insulating wall as shown in FIG. However, by eliminating the frame material b, the light-transmitting plate a needs to have a considerable thickness in design, and in addition, the light-transmitting plate a is liable to be bent or shaken due to a wind load, and to be cracked or dropped. Falling due to the collision of an accident vehicle is also a problem, and how to solve these problems is a problem.

In order to increase the rigidity of the light-transmitting plate made of a synthetic resin so as to make the light-transmitting plate hard to bend, there is a method of inserting a nylon fiber or the like into the light-transmitting plate.
In addition, there is a problem in inserting a steel wire having a different coefficient of thermal expansion. Increasing the thickness of the light-transmitting plate as described above is effective in preventing bending and shaking, but increases the cost and increases the weight, resulting in reduced workability. In particular, when polycarbonate having excellent impact resistance is used, the maximum thickness of the molded article is about 12 mm, and it is necessary to laminate the composite layer into two or three layers in order to make the thickness more than that. If a composite board is used, the cost is further increased. Although it is conceivable to use glass having high rigidity without using synthetic resin, there is a risk of secondary disaster due to scattering of cracks upon impact.

Accordingly, the present invention solves the above-mentioned problems and prevents the light-transmitting plate from being bent or swayed by wind load without making the thickness of the light-transmitting plate unnecessarily large. It is an object of the present invention to provide a light-transmitting sound-insulating wall in which the light-transmitting plate is prevented from falling due to the light-transmitting plate and the surrounding scenery is not blocked.

[0007]

In order to achieve the above object, the present invention has the following arrangement. That is, in the light-transmitting sound insulating wall according to the present invention, the light-transmitting plate is supported between the columns erected at predetermined intervals, and the light-transmitting plate has a wire insertion hole penetrating at least in the upper edge portion along the longitudinal direction. And a fall prevention wire fixed to the column is inserted into the wire insertion hole in a stretched state.

According to the present invention, at least the upper edge of the light-transmitting plate is penetrated in the longitudinal direction with the wire insertion hole, and the fall-prevention wire is inserted into the wire insertion hole in a stretched state. When a wind load is applied to the translucent plate, the fall prevention wire in a stretched state supports the wind load,
Deflection and shaking of the light transmitting plate are suppressed, and cracking and dropping due to the deflection and shaking are prevented. In particular, the upper edge portion of the light-transmitting plate which is easily affected by wind load and which is easily bent is supported by the fall prevention wire in a stretched state, so that bending and shaking can be effectively suppressed.

In addition, even if an impact due to a collision of an accident vehicle or the like is applied, since the fall prevention wire in a stretched state supports the impact, cracking of the light-transmitting plate and detachment from the support can be suppressed and breakage should occur. Even if the light-transmitting plate does not fall off the fall prevention wire, it does not fall out of the road even if it comes off the pillar.

Furthermore, since the light-transmitting plate has only the fall-prevention wire inserted at least at the upper edge, the surrounding scene is hardly obstructed.

A fixing bracket 14 for fixing the fall prevention wire 3 is attached to an upper portion of the front of the column 11 for fixing the fall prevention wire 3 with a screw 13 or the like. Is attached with a holding bracket 16 in which a holding hole 15 through which the fall prevention wire 3 is inserted is formed in a lateral direction.

Reference numeral 2 denotes a light-transmitting plate made of a synthetic resin such as polycarbonate or acrylic resin having a light-transmitting property such as transparent or translucent, glass, or the like, and its shape is generally square. It is preferably made of polycarbonate having excellent impact resistance. And each translucent plate 2
The left and right sides are abutted on the front surface of the column 1, and are supported by the column 1 by being sandwiched by support brackets 18 attached by screws 17 and the like, and are continuously formed along the longitudinal direction. Are arranged. It is preferable that the light-transmitting plate 2 is supported by the support bracket 18 so as to be slightly movable in the longitudinal direction so as not to hinder the expansion and contraction of the light-transmitting plate 2 due to thermal expansion.

Further, a wire insertion hole 21 penetrates the upper edge portion of each light transmitting plate 2 along its longitudinal direction. The wire insertion hole 21 may be formed directly on the upper edge of the light transmitting plate 2 as shown in FIG. 3, or may be formed on the light transmitting plate 2 as shown in FIG. Along the edges,
A substantially U-shaped edge member 22 having a groove may be fixed by bonding, welding, or the like, and a gap between the upper edge of the light transmitting plate 2 and the groove of the edge member 22 may be the wire insertion hole 21. Further, as shown in FIG. 5, the upper edge of the light transmitting plate 2 may be folded back into a hollow shape, and the hollow portion may be a wire insertion hole 21.

The wire insertion hole 21 needs to be formed at least along the upper edge of the light-transmitting plate 2 which is particularly susceptible to wind load and is easily bent. It may also be drilled in other parts, such as the center and the center.

Reference numeral 3 denotes a fall prevention wire, which is formed of steel, stainless steel, carbon fiber, or the like, and the material is not particularly limited. Further, the fall prevention wire 3 may be colored to make it stand out in design. The fall prevention wire 3 is connected to the plurality of light-transmitting plates 2, the wire insertion hole 21 of each light-transmitting plate 2, and the holding hole 15 of the holding bracket 16 of each support 12 to which the fall prevention wire 3 is not fixed. Each of the sections is inserted in a stretched state, and both ends of the section are fixed by fixing brackets 14 to columns 11 for fixing the fall prevention wires 3 located for each of the arbitrary number of light transmitting plates 2.

As described above, in the present embodiment, the fall prevention wire 3 is continuously inserted through the plurality of light transmitting plates 2, and is fixed to the support 11 for each of the arbitrary number of light transmitting plates 2. In order to reduce the fixing work and to increase the distance between the fixings, the holding metal 16 prevents the slack and the sway caused by the own weight of the fall prevention wire 3 from being held by the holding bracket 16 for each support 12. Further, in the present embodiment, since the plurality of light transmitting plates 2 are connected by the fall prevention wire 3, even if the light transmitting plate 2 is detached from the column 1, it is connected to another light transmitting plate 2. , Fall is prevented. In order to stretch the fall prevention wire 3, a tension means such as a spring may be used.

The fall prevention wire 3 may be fixed to the column 1 for each light transmitting plate 2. Such an embodiment will be described with reference to FIG. That is, FIG. 6 is a partially cutaway perspective view showing another embodiment of the present invention. The support 1 in the form shown in FIG. 6 is formed of an H-shaped steel having concave grooves 19 formed on the left and right. The struts 1 are erected so that the surfaces of the concave grooves 19 of the adjacent struts 1 face each other, and the left and right sides of each light transmitting plate 2 are inserted between the concave grooves 19. Thereby, the light transmitting plate 2 is supported between the columns 1. A fixing bracket 14 for fixing the fall prevention wire 3 with a screw 13 or the like is attached to the upper part of each support 1, and the fall prevention wire 3 inserted through the wire insertion hole 21 of the light transmitting plate 2 in a tight state is provided. It is fixed to the column 1 by the fixing bracket 14.

That is, in the above embodiment, the fall prevention wires 3 are fixed to the columns 1 located on both sides of the light transmitting plate 2 for each light transmitting plate 2. By doing so, the distance between the fixing of the fall prevention wire 3 is shortened, and the deflection and shaking due to its own weight are also reduced. it can.

As the fall prevention wire 3, a short wire slightly longer than the light transmitting plate 2 is used so as to be inserted into each light transmitting plate 2, and both ends thereof may be fixed to the column 1. However, in the present embodiment, a long one is used so as to be continuously inserted into an arbitrary number of the light transmitting plates 2, and the middle of the fall prevention wire 3 is fixed to the support 1 for each of the light transmitting plates 2. I have. In this way, any number of the light-transmitting plates 2 are connected by the fall prevention wire 3, so that the light-transmitting plate 2 is
Even if it is more detached, it is connected to another translucent plate 2,
Fall is prevented.

The present invention does not deny that a conventional frame material is attached to the peripheral portion of the light-transmitting plate 2, and the surrounding scene is blocked by the frame material. The material further prevents the light transmitting plate 2 from bending or swinging.

[0023]

According to the present invention, when a wind load is applied to the light-transmitting plate, the fall prevention wire in a stretched state supports the wind load, so that the light-transmitting plate can be prevented from bending or shaking. Cracks and drops due to shaking are prevented. Particularly, since the upper edge portion of the light-transmitting plate which is easily subjected to wind load and which is easily bent is supported by the fall prevention wire in a stretched state, the bending and the shaking are effectively suppressed.

In addition, even if an impact due to a collision of an accident vehicle or the like is applied, the fall prevention wire suppresses the breakage of the light-transmitting plate and the detachment from the support. As long as they do not fall off the fall prevention wire, they will not fall off the road.

Further, since the light-transmitting plate only has the fall prevention wire inserted at least at the upper edge, it hardly blocks the surrounding scenery.
