なっている。2. Description of the Related Art In the future of public works, such as seawall protection, river-banking, or slope lining, there is a demand to preserve the natural environment as much as possible. Creating an environment and creating a space that gives moisture and ease is an essential element.

地山の不陸に対応して変形しにくく、施工上の自由度が
きわめて低い等の課題があった。However, the natural stone connecting block thus formed is formed by integrally arranging natural stones in a grid pattern or in a valley-like shape (the same meaning as a staggered shape or a zigzag shape). For this reason, there is a problem in that when it is installed on a ground or the like, it is difficult to deform in response to the unevenness of the ground, and the degree of freedom in construction is extremely low.

い等の課題があった。In many cases, natural stones are arranged in a grid or valley pattern and are integrally connected by a connecting member such as a wire mesh, so that the size and shape of the natural stones are made as uniform as possible. There is a problem that natural stones of various shapes having different sizes and shapes cannot be used effectively.

てしまう等の課題があった。Further, as a method of connecting a connecting member such as a wire net to natural stone, for example, a method using a mechanical anchor which is mechanically opened and fixed in the stone when driven into natural stone,
A method of connecting to the warp or weft of the net with an annular bracket,
Furthermore, there is a method of directly fixing natural stone to the net with an adhesive, but the method using a mechanical anchor is weak to impact,
In addition, the method using an annular metal fitting generally has a small mesh gap, which may not only adversely affect the ecosystem, but also may cause one piece of damage to be continuously spread to the whole. The method often had problems such as natural stone coming off.

金具２と同様の防錆処理が施されている。As the rigid metal material, for example, a round steel bar or a deformed reinforcing bar cut to a required length is used, and both ends are bent at substantially right angles to form an anchor portion 3a having a predetermined length. In addition, the wedge-shaped bracket 3 is bridged between several adjacent natural stones 1 and 1, and anchor portions 3a at both ends are inserted into the fixing holes 1a of the natural stone 1 and a solidifying agent for fixing is provided around the fixing holes 1a. 6 are filled. In this way, the several natural stones 1 and 1 are integrally connected by the wedge-shaped bracket 3, so that a certain rigidity of the entire structure is secured. The wedge-shaped fitting 3 is also subjected to the same rust-proofing treatment as the chain fitting 2.

の下側になるように引っ繰り返して設置されている。As shown in FIG. 4, for example, as shown in FIG. 4, the environmental natural stone group multidirectional fastening structure 5 formed as described above is used for roads, seashores, harbors, rivers, and slope lining materials such as embankments and retaining walls. It is installed as. In this case, in any of the construction examples, the environmental natural stone group multi-directional fastening structure 5 uses the chain fitting 2, the wedge-shaped fitting 3, and the fixing fitting 4 as the natural stone 1.
It is repeatedly installed so that it is underneath.
【００１８】このように設置されていることで、チェー

した構造物ができる。The present invention is as described above. In particular, since any natural stones are movable by being fastened with chain fittings, the natural stones can freely follow the shape (non-land) of the ground at the time of construction. Since it can be installed, the workability is extremely high, the effect of engaging natural stones is increased, and a structure that is stable against external forces (running water, slip, load) can be formed.

わめてよい。Further, since the chain fitting is installed on the ground with the connection side of the chain fitting facing downward, the chain fitting cuts into the ground and functions as a spike for fixing natural stone on the ground. Can also be installed. In addition, a certain degree of rigidity is secured by the fact that some of the natural stones are fastened in multiple directions with wedge-shaped brackets, especially when reversing the product during manufacture, transporting it to the site, and even installing it. For example, the handling is easy and the workability is extremely good.
