Since the said patent document 1 installs a photovoltaic power generation panel in an inclined state using the curved surface which protrudes to the road side formed in the upper part of a soundproof wall, it can take in sunlight energy efficiently.
However, there is a description that a space of at least 3 m in height must be secured above the roadway at the building limits stipulated in Article 12 of the Road Structure Law. In order to comply with this road structure law, it is necessary to form the curved surface at a height of 3 m or more from the roadway. As a result, if the installation area of the photovoltaic power generation panel is sufficiently secured, the soundproof wall becomes very tall, and the construction cost becomes expensive. In addition, it is very difficult and troublesome to maintain and maintain the equipment at the high part of the soundproof wall, and the work takes time and costs.

In that respect, since the soundproof wall provided with the solar power generation panel disclosed in Patent Document 2 is configured to install the solar power generation panel using an inclined surface protruding to the private side, the height of the soundproof wall is set. It can be constructed to 3 m or less, and maintenance of the facilities is easy. Moreover, by using the inclined surface of the exterior plate, a sufficient installation area of the photovoltaic power generation panel can be secured, and solar energy can be taken in efficiently.
However, attaching a sawtooth shaped exterior panel to the private side of a soundproof panel installed along the road's extension direction requires a lot of cost in the production of the exterior panel, and the installation work is also very troublesome. This is time consuming and expensive. Further, when the vehicle collides with the soundproof wall, there is a high possibility that the solar power generation panel will be damaged along with the soundproof wall due to the impact force. Further, when the solar power generation panel is damaged, a newly prepared solar power generation panel is to be re-installed, which is very expensive.

The soundproof wall provided with the solar power generation panel disclosed in Patent Document 3 is configured to attach the solar power generation panel directly to the upper portion of the soundproof wall curved so as not to protrude toward the road side. The height can be set to 3 m or less, and there is no need to attach an exterior plate as in the soundproof wall disclosed in Patent Document 2. Furthermore, even if the vehicle collides with the soundproof wall, the photovoltaic power generation panel is installed on the upper part of the curved portion that is not directly impacted, so that it is recognized that the possibility of damage to the photovoltaic power generation panel is low.
However, when attaching a photovoltaic power generation panel to a curved surface, an attachment method with special processing is required to stabilize the photovoltaic power generation panel. Installing a large number of photovoltaic power generation panels along the road's extension direction using the above-mentioned special mounting method requires a great deal of cost for the processing, and a lot of burden is placed on the workers even during the installation work. It takes. In addition, the soundproof panel to be attached to the curved surface is limited to polycarbonate which can be curved, etc., and it is difficult to attach a metal panel with sound absorbing performance effective as a soundproof function, so there is also a problem with the performance as a soundproof wall There is.

  The purpose of the present invention is to form a pillar shape that protrudes to the private side, so that even if the soundproof wall is constructed at a height of 3 m or less from the roadway in compliance with the construction limit, the same character shape is used. The photovoltaic power generation panel can be installed in an inclined state between the inclined portions of the support columns. Furthermore, the installation structure of the photovoltaic power generation panel is very simple, and the photovoltaic power generation panel can be installed easily and quickly. It is possible to provide an inclined soundproof wall including a solar power generation panel that can prevent damage to the solar power generation panel even when a vehicle collides with the soundproof wall.
