Description

  INDUSTRIAL APPLICABILITY The present invention can be suitably used in areas where high-rises are progressing in surrounding areas such as highways and railroads, and of course, does not waste existing soundproof walls for new construction work, while preserving the living environment. The present invention relates to a construction method and a soundproof structure for a soundproof structure capable of taking measures against noise.

As is well known, it is necessary to provide a soundproof wall or the like on the side edge of a viaduct that is a concrete structure on an automobile road or railroad in order to prevent noise in the surrounding area.
The sound barrier is required to have sufficient durability to withstand strength, impact, and the like. For this reason, conventional sound barriers are constructed with cast-in-place concrete, or steel posts with H-shaped cross-sections are installed upright at regular intervals along the road surface of the viaduct or the side edge of the road. A self-supporting soundproof wall has also been developed in which horizontally long plate-shaped soundproof panels are vertically stacked between mating struts or are reinforced with fibers or the like and lightened.

  In recent years, in the vicinity of expressways and railways, especially in neighboring areas such as interchanges and stations, there has been a tendency to increase the number of high-rises such as high-rise condominiums. Noise issues have been addressed.

Thus, although the conventional method of raising the noise barrier can expand the height range of the sound insulation region, the side view is further obstructed for the driver of the automobile and the train passenger of the railway. Therefore, I could not enjoy the scenery and even felt a sense of pressure.
In addition, since the concrete soundproof wall becomes higher, the appearance from the surroundings becomes more inorganic. For this reason, the kite was also recognized as a huge structure, and the scenery was greatly damaged.
Furthermore, the high concrete soundproof wall becomes an obstacle that prevents sunlight to the surrounding environment. Therefore, protection of sunshine rights becomes a new problem.
Therefore, a method and a structure that can solve the above-described problems and can be applied to new construction work as well as an improvement of an existing soundproof wall have been desired.

  The present invention has been proposed in view of the above, and by installing a translucent sound insulation board on the top of the sound insulation wall, it is possible to take measures against noise while maintaining the living environment characterized by expanding the height range of the sound insulation area. The present invention relates to a construction method of a soundproof structure.

  Further, the present invention is a soundproof structure in which the soundproof panels are fixed in a row by foundation bolts, and the soundproof panel includes a bottom surface portion, a wall portion rising from one side edge of the bottom surface portion, and side portions on the left and right. A soundproof structure characterized in that a light-transmitting sound insulation board is attached to a precast concrete panel body including

  In the present invention, the height range of the sound insulation area can be expanded by the translucent sound insulation board added to the upper part of the sound insulation wall, so that noise countermeasures can be taken for residents such as high-rise apartments in the surrounding area. In addition, for example, compared with a case where a concrete soundproof wall is extended, a driver of a car or a train passenger of a railroad can enjoy the scenery through a translucent plate. Therefore, the ride time is very comfortable for travelers, and not only the destination but also the scenery on the way can be enjoyed. In addition, the driver of a car is less mentally fatigued due to various changes in the field of view. Moreover, the translucent sound insulation board is transparent even when viewed from the surroundings, and therefore does not have a visual sense that the scenery is damaged. Furthermore, the translucent sound insulation board does not interfere with the sunshine to the surrounding environment, and thus contributes to the problem of protecting the sunshine right.

  In addition, the present invention can be applied not only to new construction work but also to improvement of existing soundproof walls, and does not waste materials, and has many effects by relatively simple construction. It is something that can be done.

  The present invention is not limited to existing and new installations. For existing installations, for example, traffic facilities where noise countermeasures have already been requested by residents and the like are typical examples. All such lines are listed as applicable targets.

  The height of the translucent sound insulation board may be set appropriately depending on the height of high-rise apartments in the surrounding area, etc., but in the new construction, a concrete-made soundproof wall (soundproof panel) is intentionally made low, You may make a translucent sound insulation board high.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example in which the translucent sound insulation board 1 is attached to a panel body 2 made of precast concrete, and is not particularly limited to this structure, but in this illustrated embodiment, an aluminum frame 3A is shown. The example which integrates using 3D is shown. That is, the upper frame 3A, the side frames 3B and 3C, and the lower frame 3D, which are molded as shown in the drawings, are combined around the translucent sound insulating plate 1 as shown in FIGS. Attached.

  The translucent sound insulating plate 1 is most preferable because a polycarbonate resin plate is excellent in impact resistance. However, a resin plate such as acrylic or a tempered glass plate may be used for a long time. The material is not particularly limited as long as it is not broken by a collision with a stone or the like. In the illustrated embodiment, a flat light-transmitting sound insulation board is used. However, in the case of a resin board in particular, any shape such as a curved surface (curved shape) may be used because it can be freely molded.

The panel body 2 includes a bottom surface portion 21, a wall portion 22 rising from one side edge of the bottom surface portion 21, and side surfaces 23, 23 on the left and right sides. Is formed thick. Furthermore, the upper frame portion 24 of the wall portion 22 and the central portion 25 connected from the upper frame portion 24 to the bottom surface portion 21 are also formed thick. Grooves 231 or ridges 232 are formed in the vertical direction on the outer surfaces of the left and right side surface portions 23, 23, and the adjacent panels 2 and these groove 231 and ridges 232 are fitted to each other to form a gap. Can be installed side by side. Moreover, the attachment hole 211 corresponding to each upper end part 51 of the foundation bolt 5 mentioned later is opened in the bottom face part 21. As shown in FIG. If the mounting hole 211 is a long hole, position adjustment is easy.
The panel body 2 is made of precast concrete as described above, and the composition thereof is not particularly limited. The panel body 2 is produced in advance in a factory or the like by using concrete such as ordinary concrete, fiber reinforced concrete, or polymer concrete. Of these, fiber reinforced concrete is particularly desirable, and concrete that is inherently highly sound-insulating is used as the base material, and glass fiber, carbon fiber, steel fiber, etc., are mixed at an appropriate blending ratio as reinforcing fiber to increase strength and reduce weight. it can.

  The sound-insulating panel 4 comprising the light-transmitting sound-insulating plate 1 and the panel body 2 in the illustrated embodiment is configured in combination as shown in FIGS. 1 to 3 as described above. The main body 2 itself or the structure of combining them is not particularly limited, and may be combined using, for example, shape steel.

  The soundproof structure shown in FIG. 4 has a long adjustment mortar part (laying mortar part) that is flattened on the upper surface of the side edge of the slab as an installation part to be applied to railway lines and roads. The soundproof panel 4 having the above-described configuration is fixed in a row with foundation bolts (anchor bolts) 5 on the base 6 thus formed. In addition, since the surface of the slab is a very prostrate as cast-in-place concrete, an adjustment mortar portion that is flattened and leveled is provided on the upper surface of the side edge portion. This adjustment mortar portion is provided in a long length along the length direction of the side edge portion, and the upper surface is finished with a trowel or the like to form a flat surface.

  When the soundproof panels 4 are sequentially arranged in parallel on the base 6 in this way, in the illustrated embodiment, the grooves 231 and the protrusions 232 formed on the outer surfaces of the side surfaces 23 and 23 as described above are fitted. However, the side surface portions 23 and 23 may be further fixed by the connecting bolt 7, and the side frames 3 </ b> B and 3 </ b> C of the translucent sound insulating plate 1 may be fixed by the connecting plate 8. By adopting such a structure, the stability of the soundproof structure is strengthened, noise is not leaked, and the soundproofing effect is improved.

  In the above description, the new construction is described in which the soundproof panel 3 in which the panel main body 2 and the translucent sound insulation board 1 are integrated in advance is fixed. However, when an existing soundproof wall (soundproof panel) exists. The translucent sound insulation board 1 may be extended to the existing sound insulation panel, for example, by the procedure described above.

FIG. 5 schematically shows the utility of applying the soundproof structure of the present invention to an existing soundproof wall.
The existing soundproof wall 9 is made of cast-in-place concrete, and there is no problem in strength even at present, but the noise problem has been addressed due to the recent rise in the surrounding area. . Such a soundproof wall 9 has almost the same height as the train T.
When the translucent sound insulation board 1 is attached to the upper part of the soundproof wall 9, the height range of the sound insulation area indicated by the two-dot chain line can be enlarged as shown in the figure, and noise countermeasures can be taken for residents such as high-rise apartments in the surrounding area.
In addition, the translucent sound insulation board 1 does not interfere with the sunshine (indicated by the dotted line) to the surrounding environment as compared with the case where a concrete soundproof wall is extended. It will also contribute to the problem of protecting the right to sunshine in the district.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed.
