Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of pillars arranged side by side at a predetermined interval along a road, a soundproof panel installed between the pillars, and a top portion of the pillar and the soundproof panel. Belonging to the technical field of road soundproof walls consisting of a headstock and / or a short translucent plate, for example, the work of attaching and removing the headstock is made extremely possible by devising the structure of the headboard member that constitutes the headstock. The present invention relates to a road soundproof wall that can be easily performed.

[0002]

2. Description of the Related Art Conventionally, a road soundproof wall composed of a plurality of pillars, a soundproof panel installed between the pillars, and a head tree arranged on the tops of the pillars and the soundproof panel is disclosed in, for example, Japanese Patent Laid-Open No. 55-55. It is well known as described in JP-A-30004 and JP-A-57-1651.

Further, a low-layer sound insulation wall in which a translucent plate is attached to the upper end of a normal sound insulation wall at the boundary between a sidewalk and a road in an urban area is disclosed by the present applicant in Japanese Patent Laid-Open No. 2000-87317. .

As described above, a road soundproof wall with a headstock is conventionally known. Further, there is also known a soundproof wall having a low height and a translucent plate attached to the top thereof. However, when installed between the sidewalk and the roadway, the Kasagi functions as a highly safe handrail, and when viewed from the driver of a car traveling along the road, the Kasagi continues in a straight line to guide the eyes. I didn't see a road noise barrier with a structure.

The translucent plate which is fixed by a headliner and stands upright almost vertically has the effect of increasing the effective height of the soundproof wall without obstructing the field of view, but as an attachment structure of the translucent plate, an opaque outer frame or the like is used. I didn't even see Kasagi, which has a simple structure that does not require the structure, and which has a structure that is easy to handle when the translucent plate is not attached.

[0006] Therefore, the applicant of the present invention, the above-mentioned Japanese Patent Application 2002-
36708 (filing date: February 14, 2002) developed a road noise barrier. The specification and drawings relating to this road soundproof wall have a function of a highly safe handrail, which has not been seen in the past, and a function of guiding a line of sight when seen from the driver of an automobile running on a roadway. As a mounting structure of No. 3, a Kasagi having a simple structure that does not require an opaque outer peripheral frame and a structure that is easy to handle when a translucent plate is not mounted is described. Therefore, the soundproof wall for roads equipped with this umbrella is
It can be said that the degree of expectation in the industry is extremely high.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the road soundproof wall according to the present invention will be described below with reference to the drawings.

The soundproof wall for roads shown in FIGS. 1 and 2 is 2 m along the shoulder portion of the road 11 that separates the sidewalk from the roadway.
A plurality of columns 1 arranged in parallel at a certain interval, a soundproof panel 2 installed between the columns 1 and 1, and a head tree 4 arranged on top of the columns 1 and the soundproof panel 2,
And a transparent plate 3.

In the illustrated embodiment, three beam members 5 are attached in parallel in the vertical direction on the side of the road between the columns 1 ... Which are standing upright. The soundproof panel 2 has a soundproof function and the beam member 5 has a protective function. It is configured to use together. However, the structure is not limited to the structure in which the soundproof panel 2 and the beam member 5 are used in combination, and the soundproof wall can be implemented by the soundproof panel 2 alone. In FIG. 1 and FIG. 2, the black dots on the surface of the soundproof panel 2 represent sound absorbing holes provided on the roadside surface of the soundproof panel 2.

The translucent plate 3 is fixed by a cover 4 attached to the upper end of the soundproof panel 2 and stands upright vertically. Therefore, the transparent plate 3 functions as an extension of the soundproof wall. The light-transmitting plate 3 is, for example, a transparent acrylic plate, and the lower portion thereof is continuously fixed in the longitudinal direction of the road by the head 4 and stands upright.

In the illustrated example, the translucent plate 3 having a length of about 2 m, which is approximately equal to the length of the soundproof panel 2, has an interval of 20 mm in consideration of correction of mounting error and thermal expansion of the translucent plate 3. Although H is provided and fixed, the present invention is not limited to this and is merely an example. For example, a long translucent plate that straddles a plurality of columns 1 ... And soundproof panels 2 can also be used.

As a precondition for the structure, the headstock 4 has a plurality of columns 1 ... Which are arranged in parallel, and a plurality of columns 1 having a length of about 2 m which is substantially equal to the lengths of the soundproof panel 2 and the translucent plate 3. Are arranged in a continuous state on the tops of the plurality of soundproof panels 2 ... Installed between them (the invention according to claim 5).
Due to the headboard 4, the translucent plate 3 is arranged so as to be continuous with the tops of the plurality of columns 1 ... And the soundproof panel 2. Of course, the length of the headboard 4 used is not limited to this, and just like the case of the translucent plate 3, only one example is shown.

Therefore, although the translucent plate 3 has a height of about 200 mm as an example, the height is an extension of the soundproof wall, and has the effect of increasing the effective height of the soundproof wall without obstructing the view. And the appearance of the clear, clear Kasagi 4 in a straight line is as seen from the driver of the car on the road.
It is excellent in the visual line guiding effect. However, translucent plate 3
Can be installed only partly in the longitudinal direction of the soundproof wall, depending on the condition of the noise source on the road.

Although the heights of the upper ends of the pillars 1 and the upper side of the soundproof panel 2 are substantially equal, the upper side of the soundproof panel 2 has a length that is substantially the entire length of the upper side of one end of the soundproof panel 2. Has a receiving groove 12a that opens inward in the horizontal direction, and a projecting piece 12b that hangs along the side surface of the soundproof panel 2 at the other end.
