And a reinforcing transverse member 22 is arranged between the support legs 18 as necessary. In addition, in this pseudo stone block, the length of the support leg is appropriately set according to the purpose of use, and the anchor member 1 is changed according to the weight of the pseudo rock main body 12.
Needless to say, the cross-sectional dimensions, shape, and the like of 6 can be appropriately set or changed.

The artificial stone block 10 according to the present invention comprises:
It is preferable to manufacture according to the following procedure. That is, as shown in FIG.
A holding mold frame 24 made of a hard female mold made of, for example, FRP resin or the like and formed so as to form a rough outer shape and be divided into several parts is prepared.
A silicone rubber (surface transfer material) 26 having an appropriate fluidity is poured into the inner surface of the substrate to a thickness of about 1 cm.

Next, while the poured silicone rubber 26 has fluidity, the resin-based mortar 28 is cast into a thickness of, for example, 3 cm or more, and the compaction of the resin-based mortar 28 is performed manually. Performed by At this time, the resin-based mortar 28 randomly bites into the silicone rubber 26 having fluidity according to the strength of the compaction force by hand and the shape of the hard holding mold frame 24, and is compacted into a complex shape. . As a material to be cast inside the silicone rubber 26, for example, mortar concrete and the like can be suitably used in addition to the resin mortar.

After the compaction of the resin mortar 28 is completed, concrete 30 is poured with the support leg 18 of the anchor member 16 facing a predetermined position inside the holding formwork 24, and the resin mortar 28 and the concrete 10 After curing and curing, the holding mold frame 24 is separated from the mold, and high-pressure water or the like is sprayed on the silicon rubber 26 remaining on the surface of the pseudo stone body 12 to remove it.

The pseudo stone main body 12 thus formed has a rough appearance along the holding frame 24, but the surface thereof has a silicone rubber 26 having fluidity.
Since the resin mortar 28 is hardened in a state of biting randomly, for example, a natural stone pattern 14 that is delicate and tasteful like a serpentine is formed, and is installed in a place close to the viewpoint. Inconvenience that gives a sense of incongruity even when used for an application can be avoided.
