DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-transmitting soundproof panel used for a light-transmitting soundproof wall provided on a side of a road.

[0002]

2. Description of the Related Art In a residential area or the like, a soundproof wall is provided on a side of an expressway or the like in order to prevent vehicle noise from dissipating to the surroundings. In recent sound barriers, translucent panels have begun to be used to improve the impression on drivers and passengers. As the translucent panel, there is a reinforced synthetic resin plate such as polycarbonate. The light-transmitting panel is incorporated in a strength member such as a shaped steel forming a skeleton of the soundproof wall while four sides are supported by a metal frame. Depending on weather conditions, a large wind pressure may be applied to the installed soundproof wall, causing the soundproof wall to bend. When the vehicle is separated from the support portion by bending, the light-transmitting panel falls on a road, a house, a structure, a field, or the like where the vehicle is running. As a result, a great danger is given to a car, a pedestrian and the like.

In order to prevent the light-transmitting panel from dropping, it is necessary to provide a support that gives a large physical restraining force to the four sides of the light-transmitting panel. However, such a support mechanism generally has to have a complicated structure, and not only increases the cost of the soundproof wall, but also requires complicated and troublesome construction work. Therefore, various frames have been conventionally proposed for fixing the translucent panel by a simple mechanism. For example, in Japanese Patent Application Laid-Open No. 64-1807, a rectangular frame having a concave portion formed inside is used, and the four sides of the translucent panel are inserted into the concave portion inside the frame without using bolts, screws and the like. In addition, the structure of the frame is designed to withstand the wind pressure applied to the translucent panel by devising the cross-sectional shape of the frame. In JP-A-4-302608,
A frame in which one side of a translucent panel is fixed and the remaining three sides are sandwiched is introduced.

[0004]

The laid translucent panel is subject not only to wind pressure but also to expansion and contraction caused by a mechanical shock or a temperature difference. Wind pressure can be tolerated to some extent by a translucent panel sandwiching four sides. However, JP
In the sandwiching structure with the theme of wind pressure resistance as disclosed in JP-A-1807, the movable distance of the translucent panel that slides along the vertical rail or the horizontal rail of the frame must necessarily be set short. For this reason, there is a dislike for lack of flexibility with respect to expansion and contraction caused by a mechanical shock or a temperature difference generated at the time of a collision or contact of a vehicle. In this regard, Japanese Patent Application Laid-Open No. Hei.
In the structure in which one side of the light-transmitting panel is fixed as disclosed in Japanese Patent Application Laid-Open No. 8 (1999) -1995, mechanical shock applied to the light-transmitting panel is released to the non-fixed side, so that the light-transmitting panel is prevented from being broken. In addition, since the detached light-transmitting panel is prevented from falling by the fixing portion, the danger given to the periphery is reduced. However, in Japanese Patent Application Laid-Open No. 4-302608, since the subject of the translucent panel is broken or dropped due to a mechanical impact, a hanging structure in which the upper side of the translucent panel is fixed to a frame is employed. This structure lacks flexibility against expansion and contraction.

[0005] The translucent panel is used for temperature rise during sunshine, night time,
Although expansion and contraction are repeated due to a temperature drop in winter or the like, the influence of expansion and contraction tends to be greater on the longer side of the translucent panel. If such a long side is fixed,
When the stress caused by expansion and contraction exceeds the material strength of the translucent panel, the translucent panel generates defects such as cracks and chips. In addition, deterioration and crystallization are promoted by the stress,
This may cause the light-transmitting panel to devitrify. The present invention has been devised to solve such a problem. By adopting a method of fixing the short side of the translucent panel, the resistance to mechanical shock and expansion / contraction is increased. The purpose of the present invention is to provide a light-transmitting sound-insulating panel on which a sound-insulating wall can be constructed with simple construction.

[0006]

In order to achieve the object, a light-transmitting soundproof panel of the present invention has a rectangular panel body made of a light-transmitting synthetic resin, and upper and lower edges of the panel body.

., Which are inserted along the insertion holes 142, 142,.
18, the left edge 140 of the panel main body 100 is fixed to the left frame 500. Further, since the tips of the projecting pieces 522 and 522 are pressed against the opposite surface of the panel body 100, the fixed state is ensured. In this manner, the panel body 100 includes the upper edge 110 and the lower edge 12.
0 and right edge 130 are inserted into upper frame 200, lower frame 300 and right frame 400, respectively, and left edge 1
40 is fixed to the left frame 500. Therefore, the panel main body 100 includes the frames 100, 200, 300, 4
The left edge 140 is maintained at a fixed position in the square frame formed by 00, but the other edges 110, 120, and 130 are slightly movable.

The left and right frames 400, 500 assembled to the panel main body 100 are inserted between H-shaped steels 600, 600 as a skeleton of a soundproof wall as shown in FIG. 3, and leaf springs 610, 610 are connected to the frame main body. 410, 510 and H
It is interposed in the gap between the section steels 600,600. H-section steel 60
0,600 are erected on the concrete foundation 611 (FIG. 4) at intervals of about 2 m according to the size of the unit panel. The heights of the H-section steels 600, 600 are determined according to the number of stacked unit panels. Upper and lower frames 200, 30
Zeros are stacked by the number of steps corresponding to the height of the soundproof wall to be constructed. FIG. 4 shows a state where the panel main bodies 100 are stacked in two stages. The lower frame 300 on the upper side is stacked on the upper frame 200 on the lower side. Upper frame 200
A loading piece 317 formed on the frame body 310 of the lower frame 300 is attached to a shoulder 217 formed on the frame body 210 of the lower frame 300.
Are fitted, so that the positioning of the lower frame 300 on the upper side with respect to the upper frame 200 on the lower side is easily performed.
In addition, since the gap between the upper frame 200 and the lower frame 300 is closed by the stacking pieces 317, the soundproofing effect is also improved.

It is preferable that the contact surface between the upper frame 200 and the lower frame 300 be inclined in order to accurately maintain the vertical positional relationship. That is, the upper surface 219 of the frame main body 210 is inclined downward from the shoulder 217, and the bottom surface 319 of the frame main body 310 is inclined downward at the same inclination angle from the loading piece 317. The upper surface 21 thus inclined
When the lower surface 9 and the bottom surface 319 are overlapped, gravity in the left direction in FIG. 4 acts on the lower frame 300 on the upper side. However, since the movement of the loading piece 317 is regulated by the shoulder 217, the lower frame 300 on the upper stage side is maintained in the initial positional relationship. The soundproof wall is erected on the side of a highway or the like so that the holding members 320 and 420 are outside the road. As a result, various devices of the soundproof wall are not exposed on the roadway side, and a good-looking finish is obtained. In addition, H-section steel 600 and frame 2
Since leaf springs 610 and 610 are interposed between the springs 00 and 300, even if the vehicle comes into contact with or hits the soundproof wall, some impact is absorbed by the elastic deformation of the leaf springs 610 and 610.

The multi-stage soundproof walls are provided with wire ropes 6 so that individual unit panels do not come off due to any impact.
At 30 they are interconnected. The wire rope 630 is inserted through the pipes 411 and 511 to connect adjacent unit panels. Pipes 411 and 511 are connected to frames 410 and 5
10, mounting brackets 412, 413 and 512,
513 are formed with openings 631, 631,... Through which the wire rope 630 is inserted. In the example of FIG. 1, since the frame bodies 410 and 510 whose internal spaces are formed in a rectangular cross section are used, the wire rope 63 is used.
Pipes 411 and 511 are required to smoothly pass 0. However, as shown in FIG. 5, when a frame having a U-shaped cross section with one side opened is used as the frame bodies 410 and 510, the wire rope 630 can be smoothly inserted even if the pipes 411 and 511 are omitted.

Frames 200, 300, 400, 500
Al is used in consideration of corrosion resistance, light weight, workability and the like. On the other hand, the panel main body 100 is made of a synthetic resin plate such as polycarbonate having good translucency. Therefore, the panel main body 100 includes the frames 200, 300, 4
It has a thermal expansion coefficient that is about three times larger than that of 00,500. If the four sides of the translucent panel main body 100 are fixed or sandwiched by a rectangular frame due to a large difference in thermal expansion, the thermal expansion causes the translucent panel main body 100 to be deformed. As a result, the translucent panel main body 100 is wavy, and the appearance is deteriorated. Further, even if it is not deformed, the synthetic resin is deteriorated or devitrified by the thermal stress. In this regard, in the present invention, only the left edge 140 of the translucent panel main body 100 is restricted, and the other edges 110,
Since the frames 120, 130 are inserted into the frames 200, 300, 400, expansion due to temperature rise and contraction due to cooling are absorbed by the sliding motion of the edges 110, 120, 130 in the frames 200, 300, 400.

This restrained state is also effective against wind pressure. When the wind pressure F is applied to the panel main body 100, as shown in FIG.
120) along the short side (left and right edges 13).
(0,140) is small. In consideration of the amount of deformation due to the wind pressure F, it is effective to hold the upper and lower edges 110 and 120 between the frames 200 and 300 in a slidable manner, and to slide the upper and lower edges 110 and 120 to absorb the deflection. . On the other hand, in the method in which the upper edge 110 or the lower edge 120 having a large amount of deflection is restrained, the wind pressure F acts on the panel body 100 as a stress, so that defects such as breakage are easily generated.

The upper and lower frames 200, 300 are held between the left and right
The left and right frames 400, 500 at 20,620 (FIG. 3)
Connected to. Therefore, the framework can be very easily formed without requiring an L-shaped connection fitting or the like. In addition, since it is based on a split type, assembly to the panel main body 100 is reliably performed. In particular, the split type is effective when constructing a curved soundproof wall. That is, in the case of a curved sound-insulating wall, the left and right frames 400, 500 are bent at a predetermined curvature. However, since the left and right frames 400, 500 are divided, the frame bodies 410, 510 and the pressing members 420, 520 of the frames 400, 500 are used. Bending work becomes easy.
In the case of an integrated frame, the gap into which the edge of the panel main body 100 is inserted is easily crushed during bending, making the frame unusable.

EXAMPLE Polycarbonate having a height of 1000 mm, a length of 1960 mm and a thickness of 5 mm was used as the panel body 100. The 6063 alloy was extruded to a frame body 210, 310, 410, 510 and the pressing member 220,320,420,520 having a sectional shape shown in FIG. 1, after the T ₅ treatment, the anodized film with a thickness of 9μm and Film thickness 7
A μm electrodeposition film was applied. The left and right frames 40
For 0,500, an extruded material having the same cross-sectional shape was used. The average thickness of each frame 200, 300, 400, 500 was set to 2 mm. Springs 230, 33
A stainless steel spring was used for the 0 and the leaf spring 610.

The wire ropes 630 are inserted into the left and right frames 400 and 500, and the mounting brackets 412, 413 and 5
12, 513 were riveted to the frame bodies 410, 510, respectively. Frame body 2 of upper frame 200
The springs 230 and 330 were inserted into the frame main body 310 of the 10 and the lower frame 300, respectively, and assembled to the upper edge 110 and the lower edge 120 of the panel main body 100.
Next, the left and right frames 400, 500 were fixed to the upper and lower frames 200, 300 with connecting screws 620, 620,. Also, the left edge 140 of the panel main body 100 is attached to the frame main body 510 of the left frame 500 by screws 141, 1.
Screwed in 41 ... Then, the pressing members 220 and 320 were hit into the frame main body 210 of the upper frame 200 and the frame main body 310 of the lower frame 300 with a mallet, and the upper edge 110 and the lower edge 120 of the panel main body 100 were pressed against the frame main bodies 210 and 310.

In this manner, the frames 200, 300, 400, and 500 were assembled on the four sides of the panel main body 100, and the unit panel was assembled. At this time, the distance from the upper edge 110 and the lower edge 120 to the panel body 10 is 30 mm.
0 is inserted into the concave grooves 211 and 311. Frame 20
A sand bag was placed on the entire surface of the panel body 100 on which 0, 300, 400, and 500 were assembled, and a uniform load of 200 kg / m ² was applied to the panel body 100. Load 200kg /
m ² corresponds to a wind speed of about 55 m / sec. Panel body 10
0 means that even if a load of 200 kg / m ² is applied, the frame 2
Each edge did not come off from 00, 300, 400, 500. Then, as shown in FIG. 7, the center point A of the panel body 100 and the frames 200,
The center points B to E of 300, 400, and 500 and the displaced positions A ′ to E ′ are measured, and the frames 200, 300, and 4 are measured.
The length of the panel body 100 slid from 00,500 was determined. The amount of deflection at each point was also measured.

[0026]

[Table 1]

As is clear from Table 1, the panel body 10
The amount of slide-out and the amount of deflection at the center point A of 0 are the largest. However, each edge 11 of the panel body 100
At the center points B to E of 0, 120, 130, and 140, although the upper edge 110 and the lower edge 120 were slightly bent, no substantial change was observed. From this, it can be seen that the panel body 100 is slightly pulled out from the right frame 400 side starting from the left frame 500 (fixed side) to absorb the bending. The relationship between the deflection and the slide-out amount shown in Table 1 is shown in frames 200, 300, and 40.
0 to 50 ° C. with the panel body 100 assembled with 0,500
The same was true when heating and cooling were repeated within the range. In this manner, the left edge 140 corresponding to the short side is fixed, and the other edges 110, 120, and 130 are slidably movable.
When the panel body 10 is sandwiched between the panel main bodies 10, 300, and 400, deformation applied by wind pressure and temperature is sufficiently absorbed, and
0 is prevented from being damaged. In addition, since the stress was dissipated, good transparency was maintained for a long period of time without deterioration or crystallization of the material of the panel body 100.

As described above, in the translucent soundproof panel of the present invention, only one short side edge of the panel body is fixed to the frame, and the other short side edge and long side edge are fixed. Is inserted into the gap of the frame. Therefore, deformation of the panel body due to expansion and contraction caused by wind pressure and temperature change applied to the translucent panel is absorbed by sliding the panel body in the longitudinal direction, and the stress that alters or crystallizes the synthetic resin of the panel body. Does not remain. Therefore, the transparency of the panel main body is maintained for a long period of time, and a light-transmitting soundproof panel resistant to breakage can be obtained. Further, when the upper and lower edges of the panel main body are inserted into the upper and lower frames, and the holding member is attached to the frame main body, the panel main body is easily prevented from coming off. In addition, since each frame is of a divided type of the frame main body and the pressing member, a frame particularly suitable for a curved light-transmitting soundproof panel or the like can be easily formed.
