That is, the fence 5 can be attached to the concrete retaining wall 2 even when the mortar is not filled.

また、上記実施形態の柵取付部材３は、ボルト６によりコンクリート擁壁２に取り付けられているため、取り付けが容易であるとともに、柵取付部材３及び柵５をコンクリート擁壁２に強固に固定することができる。 Further, since the fence mounting member 3 of the above embodiment is attached to the concrete retaining wall 2 by bolts 6, it is easy to attach and the fence mounting member 3 and the fence 5 are firmly fixed to the concrete retaining wall 2. be able to.

また、本実施形態の壁構造体１のコンクリート擁壁２は、厚さ寸法Ｗ１に均一に形成されている。そのため、コンクリート擁壁２のみを擁壁として用いず、単なる壁として用いた場合であっても、壁に形成された厚肉部分などが邪魔になることがなく、使いやすい。従って、汎用性が高い。 Further, the concrete retaining wall 2 of the wall structure 1 of the present embodiment is uniformly formed in the thickness dimension W1. Therefore, even when only the concrete retaining wall 2 is used as a retaining wall without using it as a retaining wall, the thick portion formed on the wall does not get in the way and is easy to use. Therefore, it is highly versatile.

また、本実施形態の壁構造体１は、柵取付部材３との間に設けられる調整部材４を有し、調整部材４は、側壁２１の厚さに応じた厚さ寸法Ｗ４に形成されている。このような構成により、柵５の支柱５１が配されない個所に、柵取付部材３に代えて、調整部材４を配することができるため、拡幅部３２を有する柵取付部材３のみを配する場合に比してコストを削減することができる。具体的には、拡幅部３２に相当する部分のコンクリートを削減することにより、コストを削減することができる。 Further, the wall structure 1 of the present embodiment has an adjusting member 4 provided between the wall structure 1 and the fence mounting member 3, and the adjusting member 4 is formed to have a thickness dimension W4 corresponding to the thickness of the side wall 21. There is. With such a configuration, the adjusting member 4 can be arranged instead of the fence attaching member 3 at the place where the support column 51 of the fence 5 is not arranged. Therefore, when only the fence attaching member 3 having the widening portion 32 is arranged. The cost can be reduced compared to. Specifically, the cost can be reduced by reducing the amount of concrete in the portion corresponding to the widening portion 32.

また、一般的に擁壁に柵を設ける場合には、擁壁の内側に支柱を立てる為の独立基礎を設置する必要がある。そのため、独立基礎が配される分、柵は擁壁より内側に配されることとなり、擁壁と柵との間に無駄なスペースが形成される。一方、本実施形態の壁構造体１であれば、柵取付部材３がコンクリート擁壁２に取り付けられると、柵固定部３３は、側壁２１の略上方に配されるため、柵５は側壁２１の略上方に配される。そのため、側壁２１と柵５との間の無駄なスペースを減らすことができ、コンクリート擁壁２（側壁２１）により囲われた区画の面積と、柵５により囲われた区画の面積との差を小さくすることができる。 In addition, when a fence is generally provided on a retaining wall, it is necessary to install an independent foundation for erecting columns inside the retaining wall. Therefore, as the independent foundation is arranged, the fence is arranged inside the retaining wall, and a wasted space is formed between the retaining wall and the fence. On the other hand, in the wall structure 1 of the present embodiment, when the fence mounting member 3 is attached to the concrete retaining wall 2, the fence fixing portion 33 is arranged substantially above the side wall 21, so that the fence 5 is the side wall 21. It is placed approximately above. Therefore, the wasted space between the side wall 21 and the fence 5 can be reduced, and the difference between the area of the section surrounded by the concrete retaining wall 2 (side wall 21) and the area of the section surrounded by the fence 5 can be reduced. It can be made smaller.
