DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-transmitting soundproof plate.

[0002]

2. Description of the Related Art Conventionally, soundproof walls are provided in places where noises are severe, such as roads and tracks. However, these soundproof walls are made of metal, ceramic, synthetic resin, or other opaque plates on the surface and are continuously provided along the side edges of roads, tracks, and the like. The structure is uniform and has little change. If such a uniform, monotonous sound barrier continues along the road for a long distance, the scenery of the road space is murky and the change is poor, and the psychological stress such as emotional tension and oppression given to the driver The problem is that the physical influence is large and the body and mind are easily fatigued. Also, in the case of a track, when a soundproof wall is provided, the enjoyment of viewing the scenery around the passenger is reduced by half. As a method for solving this problem, Japanese Utility Model Application Laid-Open No. 4-6111 filed by the applicant of the present invention previously filed.
A light-transmitting soundproofing plate described in Japanese Patent Application Laid-Open No. 4 (Kokai) No. 4 is known.

[0003] This transparent soundproofing plate is preferable because it is transparent and the scenery is visible, so that the driver's fatigue is reduced and the enjoyment of seeing the scenery around the passenger does not decrease. This light-transmitting soundproofing plate can be attached to a transparent plate in a rectangular frame made of a long frame material, or a long frame material having an opening along the length direction with the opening inside. A frame is formed by forming a frame in a square shape, and a peripheral portion of the light transmitting plate is inserted and held in an opening of the frame. The means for attaching the light-transmitting plate to this frame is usually as shown in FIG.
The frame 100 and the periphery 101 of the light-transmitting plate are bolted to the nut 1
02 is firmly held. Further, as shown in FIG. 4, the means for holding the frame in the opening of the frame body may be provided with a retaining pin 104 at the peripheral edge 103 of the light-transmitting plate inserted into the opening, or described in the above-mentioned publication. As described above, a protruding portion is provided so as to prevent the light transmitting plate from falling.

[0004]

However, in the method of fixing with the bolt and nut 102, since the thermal expansion coefficients of the light transmitting plate and the frame body are different, the light transmitting plate and the frame are changed by the difference in thermal expansion due to the temperature difference in summer and winter. The body may flex or break. For example, when the frame has a higher mechanical strength than the light-transmitting plate and a lower coefficient of thermal expansion, the light-transmitting plate is deformed or damaged in summer due to expansion larger than the light-transmitting plate frame. Further, in winter, there is a problem that the light-transmitting plate shrinks more than the frame and cracks occur.
In the case of attaching a retaining pin or fixing by providing a protruding portion, since the coupling between the frame and the light transmitting plate is loose, the light transmitting plate is not deformed or cracked. ,
There is a problem that the light transmitting plate slides or vibrates at a contact portion between the light transmitting plate and the frame body due to vibration due to the passage of the vehicle, wind pressure in a strong wind, and the like, so that the edge portion is easily damaged. In particular, on highways, vehicles pass at high speed, and there are many elevated parts,
Accordingly, since the vibration and wind pressure become stronger, the light-transmitting plate is easily damaged. Therefore, an object of the present invention is to provide a light-transmitting soundproofing plate that is not deformed or cracked due to a temperature difference between summer and winter, and that the light-transmitting plate is not damaged by passing of a vehicle or strong wind. Is to provide a board.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and a long frame material having an opening extending in a longitudinal direction has a rectangular shape with the opening inside. A light-transmitting soundproofing plate in which a peripheral portion of a light-transmitting plate is inserted into an opening of the frame and the light-transmitting plate is held by the frame; Elastic packing is provided in contact with both sides of the peripheral edge of the light-transmitting plate inserted into the opening of the frame, and a frame ridge is provided between at least one of the elastic packings and the inner surface of the opening.
The spacer is press-fitted between the frame pressing edge and the inner surface of the opening, and the press-fitting of the spacer presses the frame pressing edge and the elastic packings provided on both surfaces of the light transmitting plate in the opening, and the pressed elastic packing The light-transmitting plate is firmly held by the frame.

[0006]

According to the holding structure of the light-transmitting soundproofing plate of the present invention, elastic packings are provided in contact with both sides of a peripheral portion of the light-transmitting plate inserted into the opening of the frame, and the elastic packing and the inner surface of the opening are provided. And a spacer is press-fitted between the frame ridge and the inner surface of the opening. Then, the periphery of the translucent plate,
Since the spacer is forced into the opening in which the elastic packing and the frame ridge which are in contact with the both sides are inserted, they are pressed against each other, and as a result, the easily deformable elastic packing is pressed in a compressed state, and is pressed The light-transmitting plate is firmly held by the frame by the elasticity of the elastic packing to return to the original state.

As described above, the light-transmitting plate of the light-transmitting sound insulating plate of the present invention is held by the frame by the elastic packing provided on both sides of the peripheral portion inserted into the opening, so that the temperature in summer and winter can be maintained. Even if the translucent plate or the frame body expands and contracts due to the difference, the difference between the expansion and contraction is absorbed by the elastic deformation of the elastic packing. Therefore, the light-transmitting plate is not deformed, broken or cracked. Further, since the light-transmitting plate is firmly held by being sandwiched by the elastic packing, the light-transmitting plate does not slide at the contact portion between the light-transmitting plate and the frame due to the vibration or wind pressure of the vehicle. The edge does not hurt.

[0008]

Next, an embodiment in which the light-transmitting soundproof plate of the present invention is provided on a highway will be described. 1 and 2 show an embodiment of the present invention. FIG. 1 is an explanatory view showing a state in which a light-transmitting soundproof plate is used on an expressway, and FIG. 2 is a II-II of FIG.
It is sectional drawing which shows the state cut | disconnected by the line.

In FIGS. 1 and 2, reference numeral 1 denotes a steel column provided on a side edge of a highway. Reference numeral 2 denotes a light-transmitting soundproof plate. The light-transmitting soundproof plate 2 includes a frame 3 and a light-transmitting plate 4. The frame 3 is formed by forming a long frame material made of a metal such as aluminum or a fiber-reinforced synthetic resin having an opening 31 along the length direction into a square shape with the opening 31 inside. . The light transmitting plate 4 is made of a glass plate or a transparent synthetic resin plate, and a peripheral portion 41 of the light transmitting plate 4 is inserted into the opening 31. Reference numeral 5 denotes an elastic packing made of synthetic rubber, soft synthetic resin, or the like.
Each of which is in contact with both sides of the peripheral edge 41 of the light transmitting plate 4 inserted into the opening 31 of the frame 3. As shown in FIG. 2, the cross-sectional shape of the elastic packing 5 is a long body having three legs 51 provided on a surface that comes into contact with the light transmitting plate 4. Is fine. For example, the contact surface may be flat, or two or four or more legs may be used.

The frame ridge 6 is provided between the elastic packing 5 and the inner surface of the opening 31. . Reference numeral 7 denotes a spacer made of a long body such as a metal such as aluminum or a fiber-reinforced synthetic resin. The spacer 7 is press-fitted between the frame pressing edge 6 and the inner surface of the opening 31. Thus, when the spacer 7 is press-fitted between the frame pressing edge 6 and the opening 31, the light transmitting plate 4 inserted into the opening 31 and the elastic packings 5, 5 And the frame edge 6 are pressed against each other. As a result, the deformable elastic packings 5, 5 are compressed, and the elastic packings 5, 5,
The light transmitting plate 4 is firmly held by the frame 3 due to the elasticity of the light transmitting plate 4 returning to its original shape.

Next, the construction method and operation of the light-transmitting soundproof plate will be described. After one elastic packing 5 is inserted into the opening 31 of the frame material, the elastic packing 5 is sandwiched between the light transmitting plate 4 and the inner surface of the opening 31 so that the light transmitting plate 4
The frame material is assembled into a square while inserting the four peripheral edges into the openings 31 of the frame material, and the frame 3 is manufactured. Next, after the other elastic packing 5 is fitted into the frame pressing edge 6, the frame pressing edge 6 and the elastic packing 5 are opened from the end face of the frame material such that the elastic packing 5 comes into contact with the light transmitting plate 4. It is inserted between the inner surface of the part 31 and the light transmitting plate 4. This procedure may be performed before or after. For example, one packing 5 is inserted into the opening 31 of the frame material.
May be inserted, the frame ridge 6 fitted with the other packing 5 may be inserted into the opening 31, and then the peripheral edge 41 of the light transmitting plate 4 may be inserted between the two packings 5. . afterwards,
The spacer 7 is press-fitted while opening a gap between the frame pressing edge 6 and the inner surface of the opening 31. Then, the light transmitting plate 4 in the narrow opening 31 and the elastic packings 5 on both sides of the light transmitting plate 4 are formed.
And the frame pressing edge 6 is pressed, but the deformable elastic packing 5 is compressed and the spacer 7 is press-fitted. The translucent plate 4 is firmly held by the frame 3 due to the elasticity of the compressed elastic packing 5 trying to return to the original state. Thus, the light-transmitting soundproof plate 2 is manufactured.

An H-shaped support 1 is set up substantially vertically along the side edge of the highway, and the light-transmitting soundproof plate 2 manufactured by the above-described method is fitted and attached to this support. Then, a transparent translucent soundproof plate 2 is continuously provided along the side edge of the highway, and the noise generated by vehicles passing through the highway is prevented, so that the surroundings are released from the noise. Since the driver of the passing vehicle can see the surrounding scenery, mental nervousness and oppression due to the opaque soundproof board as in the past is eliminated, fatigue is reduced, and traffic accidents are reduced. The difference in thermal expansion and contraction between the frame 3 and the light transmitting plate 4 due to the temperature difference between summer and winter is absorbed by the deformation of the elastic packing 5. Therefore,
The light-transmitting plate 4 and the frame 3 are not deformed, broken, or cracked. Also, the vibration of the light transmitting plate 3 generated by the vibration of the vehicle passing through the highway or the pressure of the strong wind is absorbed by the elastic packing 5 and the elastic packing 5 firmly holds the light transmitting plate 3. The light plate 3 does not slide, so that the periphery of the light transmitting plate 3 does not hurt.

[0013]

The light-transmitting soundproofing plate of the present invention can be installed along the side edges of a road or a track to prevent noise and to be transparent, so that it can obstruct the lighting around the road. No, and if a transparent soundproofing board is used, the surrounding scenery can be seen, so driver fatigue is reduced,
Driving becomes easier. As a result, the number of accidents is reduced, and the pleasure of viewing the scenery of the passenger is not reduced. Further, in the light-transmitting soundproof plate of the present invention, since the periphery of the light-transmitting plate is firmly held by the elastic packing, the elastic packing absorbs the deformation of the light-transmitting plate due to the temperature difference in summer and winter, and the light-transmitting plate and the like. The frame does not deform, break or crack. Also, the vibration of the light-transmitting plate due to the vibration of the vehicle or the wind pressure is absorbed by the elastic packing, and the elastic packing firmly holds the light-transmitting plate, so that the light-transmitting plate does not slide. But does not hurt.
