Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a soundproof wall installed along the direction of travel of roads and railways in order to prevent noise pollution from automobiles and trains.

<Prior Art> As a conventional soundproof wall, there is one shown in the cross-sectional view of FIG. In the figure, a sound insulating wall 1 has sound absorbing tiles 4, 4, . . . fixed to the sound source side surface of a sound insulating wall 2 via spacers 3, 3, . To explain in more detail, the sound insulating wall 2 is made of commonly used reinforced concrete, and a formwork (not shown) is provided on the foundation, reinforcing bars 21, 21 are arranged, and a concrete material 22 is placed inside the formwork. It is formed as a continuous rigid wall by pouring. Spacers 3, 3... are fixed to the sound source side surface of the sound insulating wall 2 through mortar 5a, 5a..., and mortar 5b, 5b
Sound-absorbing tiles 4, 4, etc. made of porous ceramic or the like are fixed through...

In such a state, gaps 6, 6, . . . for reducing sound pressure are formed between the sound insulating wall 2 and the sound absorbing tiles 4, 4, .

<Problems to be Solved by the Invention> However, in the above-mentioned soundproof wall 1, it takes time to construct the soundproof wall 2, and it also takes time to cure the concrete material 22. Since the work of fixing the sound absorbing tiles 4 to the sound insulating wall 2 is mainly done manually on site, the fixing becomes uneven and the sound absorbing tiles 4 are likely to peel off. Another problem was that the construction period was delayed due to weather conditions.

On the other hand, since the sound-absorbing tiles 4 are rigidly connected to the sound-insulating wall 2 via the spacers 3, 3, . . ., they cannot freely resonate with the sound pressure of the noise. Therefore, the sound absorption effect cannot be fully exhibited.

<Means for Solving the Problems> In order to solve the above problems, the present invention forms a soundproof wall by consecutively installing panels that form one structural unit, and the constituent panels have a plurality of panels projecting from the surface. It consisted of a sound insulating wall with integrally molded protrusions, and sound absorbing tiles adhered to the upper surface of the protrusions via an elastic adhesive.

<Function> Since the molding and pasting work can be performed in a factory by the above means, a soundproof wall can be formed simply by continuously arranging panels at predetermined positions on site. Since the sound-absorbing tiles are attached with an elastic adhesive, they can freely resonate with the sound pressure of the noise.

<Example> The present invention will be described below based on the drawings. FIG. 1 is a partially cutaway perspective view showing the panel 7. FIG. In the figure, a sound-absorbing tile 72 is fixed to a sound-insulating wall material 71 and its surface facing the sound source. The sound insulating wall material 71 is formed into a rectangular plate material by extrusion molding an asbestos cement material or the like. This sound insulation wall material 71
has hollow parts A, A... and a protrusion B on one side end surface.

An elastic adhesive 73 is continuously applied in a bead shape to the upper surfaces d, d..., and the sound absorbing tiles 72, 72 are applied via the elastic adhesive 73, 73.
... is pasted. The sound-absorbing tile 72 is made of porous ceramic or the like, and is a rectangular plate having a dimension substantially equal to the width of the sound-insulating wall material 71. A plurality of sound-absorbing tiles 72, 7 are provided on one sound-insulating wall material 71.
2... are pasted in a vertical line. Moreover, the protruding body D,
D... has a predetermined projecting dimension and is protruded in a parallel state, and gaps 6, 6... for sound pressure reduction similar to the conventional one are formed between the sound insulating wall material 71 and the sound absorbing tile 72.

The on-site installation of the panel 7 having the above configuration will be explained. FIG. 2 is a cross-sectional view of the soundproof wall 1. Anchor materials 8, 8... are erected in advance at a predetermined interval on the site, and this interval is
...corresponds to the predetermined interval. As the anchor material 8, a shaped steel material or the like having sufficient dimensions to fit into the hollow portion A is used. Hollow part A in this anchor material 8

8, an adjacent panel 7 is arranged in the same manner as described above. At this time, the protrusion B of the panel 7 and the adjacent groove C of the panel 7 are fitted with the gasket G interposed therebetween. As described above, the adjacent panels 7, 7...
are arranged to form the soundproof wall 1.

<Effects of the invention> As explained above, according to the invention, the panels, which are the main components of the soundproof wall, are manufactured in advance in a factory, so the soundproofing performance is uniform and there is no variation in shape quality. It has many advantages as a panel. Moreover, the work of pasting sound-absorbing tiles becomes easier,
Moreover, accidents such as peeling are less likely to occur. Since a soundproof wall is formed by simply arranging panels continuously on anchor materials erected on site, work efficiency on site is improved and construction schedules are not delayed due to weather conditions. Furthermore, the sound-absorbing tiles are attached with elastic adhesive and can freely resonate against the sound pressure of the noise, further improving the sound-absorbing effect.
It has good performance as a soundproof wall.
