Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a translucent soundproof panel used for a translucent soundproof wall that is erected on the side of a road.

[0002]

2. Description of the Related Art In a residential area or the like, a soundproof wall is erected on a side portion of a highway or the like in order to prevent noise of a vehicle from being diffused to the surroundings. In recent noise barriers, translucent panels have begun to be used to improve the impression given to the driver and passengers. As the translucent panel, there is a reinforced synthetic resin plate such as polycarbonate. The translucent panel is incorporated into a strength member such as shaped steel that constitutes the skeleton of the soundproof wall with its four sides supported by a metal frame. The laid soundproof wall may be bent due to a large wind pressure depending on weather conditions. If the translucent panel is detached from the supporting part due to bending, the translucent panel falls on the roadside or the roadside where the vehicle is traveling, structures, fields, etc. As a result, it poses an extremely large risk to automobiles and passersby.

In order to prevent the translucent panel from falling, a support portion that gives a large physical restraining force to the four sides of the translucent panel has been required. However, such a support mechanism generally has a complicated structure, which not only increases the cost of the soundproof wall, but also requires a complicated and troublesome construction work. Therefore, in order to fix the translucent panel with a simple mechanism, various frames have been conventionally proposed. For example, in Japanese Unexamined Patent Publication No. 64-1807, a rectangular frame having a recess formed inside is used, and the four sides of the translucent panel are inserted into the recess inside the frame without using bolts, screws or the like. In addition, the cross-sectional shape of the frame has been modified to withstand the wind pressure applied to the translucent panel. In Japanese Patent Laid-Open No. 4-302608,
A frame in which one side of the translucent panel is fixed and the other three sides are sandwiched is introduced.

[0004]

In addition to wind pressure, expansion and contraction due to mechanical shock and temperature difference are applied to the laid light-transmitting panel. The wind pressure can be endured to some extent by the translucent panel sandwiching the four sides. However, JP-A-64
In the sandwiching structure whose subject is wind pressure resistance as in Japanese Patent Publication No. 1807, it is necessary to set a movable distance of a light-transmissive panel that slides along a vertical rail or a horizontal rail of a frame to be short. Therefore, there is a dislike of lacking in flexibility for expansion and contraction caused by a mechanical shock or a temperature difference caused by collision or contact of a vehicle. In this respect, JP-A-4-30260
In the structure in which one side of the translucent panel is fixed as in Japanese Patent Publication No. 8, the mechanical shock applied to the translucent panel is released to the non-fixed side, so that the translucent panel is prevented from being broken. Further, the detached translucent panel is prevented from falling, and the danger to the surroundings is reduced because the fixing portion prevents the translucent panel from falling. However, in Japanese Unexamined Patent Publication No. 4-302608, the subject is to damage or drop the light-transmitting panel due to a mechanical impact, and therefore, a hanging structure in which the upper side of the light-transmitting panel is fixed to the frame is adopted. This structure lacks flexibility for expansion and contraction.

The translucent panel is used for the temperature rise during sunshine and at night.
Although it expands and contracts repeatedly due to a temperature drop during winter, the effect of expansion and contraction is more likely to appear on the longer side of the translucent panel. If such a long side is fixed,
When the stress due to expansion and contraction exceeds the material strength of the translucent panel, defects such as cracks and chips are generated in the translucent panel. Also, stress promotes alteration and crystallization,
It also causes the translucent panel to become devitrified. The present invention has been devised to solve such a problem, and by adopting a method of fixing the short side of the translucent panel, the resistance to mechanical shock and expansion / contraction is increased, and The purpose is a translucent soundproof panel where a soundproof wall is constructed by simple construction.

[0006]

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

A step 515 is formed in a part of No. 4, and the protruding piece 521 of the pressing member 520 is fixed to the step 515 with a screw 516. A channel material having an appropriate cross-sectional shape is used for the pressing member 420, but it is preferable to form a plurality of projecting pieces 521 and 522 projecting toward the surface of the frame body 410. Also in this case, when the outer protruding piece 521 is screwed to the fixing piece 514, a gap 523 corresponding to the thickness of the panel body 100 is formed between the protruding piece 522 and the side surface of the frame body 510. A cushioning material 524 such as a rubber packing may be attached to the tip of the protruding piece 522 as necessary.

The frame body 5 facing the pressing member 520

... are formed. Left edge 14 of panel body 100
, Which are inserted through the insertion holes 142, 142, ...
The left edge 140 of the panel body 100 is fixed to the left frame 500 by screwing into 18 ... Further, since the tips of the projecting pieces 522, 522 are pressed against the opposite surface of the panel body 100, the fixed state becomes reliable. In this way, the panel body 100 has the upper edge 110 and the lower edge 12
0 and the right edge 130 are respectively inserted into the upper frame 200, the lower frame 300 and the right frame 400, and the left edge 1
40 is fixed to the left frame 500. Therefore, the panel body 100 includes the frames 100, 200, 300, 4
The left edge 140 is maintained in a fixed position within the rectangular frame formed by 00, but the other edges 110, 120, 130 are slightly movable.

The left and right frames 400 and 500 assembled to the panel body 100 are inserted between the H-shaped steels 600 and 600, which are the skeletons of the soundproof wall, as shown in FIG. 3, and the leaf springs 610 and 610 form the frame bodies. 410, 510 and H
It is inserted in the gap between the shaped steels 600, 600. H-section steel 60
0 and 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 height of the H-section steels 600 and 600 is determined according to the number of steps of the unit panels to be stacked. Upper and lower frames 200, 30
0 is stacked by the number of steps corresponding to the height of the soundproof wall to be constructed. FIG. 4 shows a state in which the panel 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
The shoulder 217 formed on the frame body 210 of the lower frame 300 has a loading piece 317 formed on the frame body 310 of the lower frame 300.
Are fitted together, it is possible to easily position the lower frame 300 on the upper side with respect to the upper frame 200 on the lower side.
Further, since the seat strip 317 closes the gap between the upper frame 200 and the lower frame 300, the soundproofing effect is improved.

In order to maintain the vertical positional relationship accurately, it is preferable to incline the contact surface between the upper frame 200 and the lower frame 300. That is, the upper surface 219 of the frame body 210 is inclined downward from the shoulder portion 217, and the bottom surface 319 of the frame body 310 is inclined downward from the stacking piece 317 at the same inclination angle. The upper surface 21 inclined in this way
When 9 and the bottom surface 319 are overlapped with each other, gravity in the left direction in FIG. 4 acts on the lower frame 300 on the upper stage side. However, since the movement of the loading piece 317 is restricted by the shoulder portion 217, the lower frame 300 on the upper stage side is maintained in the positional relationship at the time of construction. The soundproof wall is erected on a side portion of a highway or the like so that the pressing members 320 and 420 are located outside the road. As a result, the various equipment of the soundproof wall is not exposed on the side of the roadway, resulting in a good-looking finish. In addition, H-section steel 600 and frame 2
Since the plate springs 610 and 610 are interposed between the plate springs 00 and 300, even if the vehicle comes into contact with or collides with the soundproof wall, some impact is absorbed by the elastic deformation of the plate springs 610 and 610.

The soundproof wall made up of multiple stages has a wire rope 6 to prevent the individual unit panels from coming off due to some impact.
They are connected to each other at 30. The wire rope 630 is inserted into the pipes 411 and 511 and connects adjacent unit panels. The pipes 411, 511 are connected to the frames 410, 5
Mounting brackets 412, 413 and 512 for fixing to 10
At 513, openings 631, 631 ... For inserting the wire rope 630 are formed. In the example of FIG. 1, since the frame bodies 410 and 510 whose internal space is formed in a rectangular cross section are used, the wire rope 63
Pipes 411 and 511 are required to smoothly pass 0. However, when a mold material having a U-shaped cross-section with one side open as shown in FIG. 5 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
For Al, an Al material is used in consideration of corrosion resistance, lightness, workability, and the like. On the other hand, the panel body 100 is made of a synthetic resin plate such as polycarbonate having a good translucency. Therefore, the panel body 100 includes the frames 200, 300, 4
It has a large thermal expansion coefficient of about 3 times that of 00,500. Due to the large difference in thermal expansion, if the four sides of the translucent panel body 100 are fixed or sandwiched by the rectangular frame, the thermal expansion causes deformation of the translucent panel body 100. As a result, the translucent panel body 100 is wavy, and the appearance is deteriorated. Further, even if it is not deformed, the thermal stress causes the synthetic resin to deteriorate or devitrify. In this respect, according to the present invention, only the left edge 140 of the translucent panel body 100 is constrained and the other edges 110,
Since the method of inserting 120, 130 into the frames 200, 300, 400 is adopted, the expansion due to the temperature rise and the contraction due to the cooling are absorbed by the sliding movement 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 body 100, as shown in FIG. 6, the long side of the panel body 100 (upper and lower edges 110,
120) and bends significantly along the short side (left and right edges 13
The amount of deflection along (0,140) is small. Considering the amount of deformation by the wind pressure F, it is effective to absorb the bending by sandwiching the upper and lower edges 110 and 120 by the frames 200 and 300 so that they can slide, and sliding the upper and lower edges 110 and 120. . On the other hand, in the method of restraining the upper edge 110 or the lower edge 120 having a large amount of deflection, the wind pressure F acts as stress and acts on the panel body 100, so that defects such as breakage are likely to occur.

The upper and lower frames 200 and 300 are sandwiched by the left and right frames 400 and 500, and the connecting screw 6
Left and right frames 400 and 500 at 20,620 (FIG. 3)
Connected to. Therefore, the frame can be assembled very easily without the need for an L-shaped connection fitting or the like. In addition, since it is based on the split type, the assembly to the panel body 100 is surely performed. In particular, the split type is effective in constructing a curved soundproof wall. That is, in the curved soundproof wall, the left and right frames 400 and 500 bent at a predetermined curvature are used. However, since they are the split type, the frame bodies 410 and 510 and the holding members 420 and 520 of the frames 400 and 500 are used. The bending work for is easy.
If the frame is of an integral type, the gap into which the edge of the panel body 100 is inserted is likely to be crushed during bending, making it unusable.

The amount of sliding out and the amount of bending 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, 140, the upper edge 110 and the lower edge 120 were slightly bent, but no substantial change was observed. From this, it is understood that the panel main body 100 is slightly pulled out from the right frame 400 side with the left frame 500 (fixed side) as a starting point, so that the bending is absorbed. The relationship between the flexure and the sliding amount shown in Table 1 is as follows.
0 to 50 ℃ the panel body 100 with 0,500 assembled
The same was true when heating and cooling were repeated within the range. In this way, the left edge 140, which is the short side, is fixed, and the other edges 110, 120, and 130 are slidable.
When sandwiched between 00, 300 and 400, the deformation applied by wind pressure or temperature is sufficiently absorbed, and the panel body 10
0 damage is prevented. Further, since the stress is dissipated, the material of the panel body 100 is not altered or crystallized, and good transparency is maintained for a long period of time.

[0028]

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. The method of inserting the into the gap of the frame is adopted. Therefore, the deformation of the panel body due to the expansion and contraction due to the wind pressure and temperature change applied to the translucent panel is absorbed by the sliding of the panel body in the longitudinal direction, and the stress that deteriorates or crystallizes the synthetic resin of the panel body. Does not remain as. Therefore, the transparency of the panel body is maintained for a long period of time, and a translucent soundproof panel that is resistant to breakage can be obtained. Further, when adopting a system in which the upper and lower edges of the panel body are inserted into the upper and lower frames and the pressing member is attached to the frame body, the panel body can be easily retained. Moreover, since each frame is a divided type of the frame body and the pressing member, a frame particularly suitable for a curved type translucent soundproof panel or the like can be easily formed.
