Description

本発明は、配置用ブロックに係り、特に、簡易且つ迅速に弧状に配置することができる配置用ブロックに関する。   The present invention relates to an arrangement block, and more particularly to an arrangement block that can be easily and quickly arranged in an arc shape.

ブロック体を並設して弧状に配置する配置用ブロックがある（例えば、特許文献１参照）。この特許文献１によれば、曲率が大である円弧に配置するには、ブロック体（路盤表装材４）を交互に逆向きに突起を噛み合わせ（特許文献１の図９参照）、曲率が中である円弧に配置するには、ブロック体（路盤表装材４）は同じ向きで、ブロック体（路盤表装材４）の外側の一角を近接させ（特許文献１の図１０参照）、曲率が小である円弧に配置するには、ブロック体（路盤表装材４）は同じ向きで、ブロック体（路盤表装材４）の内側の一角を近接させ（特許文献１の図１０参照）て行うようにしている。
実用新案登録第３０４７０３５号公報 There is an arrangement block in which block bodies are arranged side by side and arranged in an arc shape (see, for example, Patent Document 1). According to this patent document 1, in order to arrange in a circular arc having a large curvature, block bodies (roadbed surface covering material 4) are alternately meshed in opposite directions (see FIG. 9 of patent document 1), and the curvature is In order to arrange in a circular arc inside, the block body (roadbed surface covering material 4) is in the same direction, and the outer corner of the block body (roadside surface covering material 4) is brought close (see FIG. 10 of Patent Document 1), and the curvature is In order to arrange in a small arc, the block body (roadbed surface covering material 4) is in the same direction, and one corner inside the block body (roadside surface covering material 4) is brought close (see FIG. 10 of Patent Document 1). I have to.
Utility Model Registration No. 3047035

しかしながら、上述した配置用ブロックにあっては、曲率の大小によってブロック体（路盤表装材４）を同じ向き、又は交互に逆向きと種々の形態があり紛らわしく、作業性が悪く、しかも、ブロック体（路盤表装材４）の側面に突出する突起が容易に欠け易く、更に、ブロック体（路盤表装材４）の上面が損傷した場合、ブロック体（路盤表装材４）の上面と底面は非対称であるため、損傷した上面を裏返して底面として利用できず、新たなブロック体（路盤表装材４）を用意しなければならないという問題点があった。
本発明は、上述した問題点を除去するようにした配置用ブロックを提供するものである。 However, in the arrangement block described above, the block body (the roadbed surface covering material 4) has various forms such as the same direction or alternately in the reverse direction depending on the curvature, and the workability is poor, and the block body is bad. When the protrusion protruding from the side surface of the (base plate surface material 4) is easily chipped, and the top surface of the block body (base material 4) is damaged, the top surface and the bottom surface of the block body (base material 4) are asymmetric. For this reason, there is a problem in that the damaged upper surface cannot be turned over and used as the bottom surface, and a new block body (roadbed surface covering material 4) must be prepared.
The present invention provides an arrangement block that eliminates the above-described problems.
