2. Description of the Related Art In conventional masonry retaining wall construction, masonry stones were piled up by masons.

[0003]

However, the above-mentioned conventional masonry retaining wall construction using sap stone has the following problems. Machiseki is a stone that has been processed into a pyramidal shape, and mainly granite and andesite are used, but it is difficult to cut out granite and andesite from the viewpoint of environmental protection and the like. In addition, the price of Majiishi has risen sharply in connection with the above, and it is expected that it will continue to be expensive. Masonry stones, etc. were mainly made by skilled masonry workers, but because the number of masonry workers has decreased due to aging and successors have not grown up, masonry stone retaining wall construction is a construction period. The fact is that the construction cost will increase as the construction time increases.

In view of such circumstances, the present invention looks like the appearance of natural stones when piled up, is inexpensive, and can be easily piled up by an unskilled person.
It is an object of the present invention to provide a masonry block that can reduce the construction period such as retaining wall construction and the construction cost.

[0005]

The stone masonry block of the present invention comprises a concrete block and natural stone attached to the front surface of the concrete block. Further, it is composed of a concrete block having a rectangular block main body and at least one block leg continuous with the block main body, and a natural stone attached to the front surface of the block main body. A convex portion is formed on the upper surface of the block leg portion, and a notch is formed on the lower surface of the block leg portion so as to fit with the convex portion on the upper surface of the block leg portion. Further, it is characterized in that it is composed of a concrete block having a block main body of an arbitrary shape and a block leg continuous with the block main body, and a natural stone attached to the front surface of the block main body. .

[0006]

In the stone masonry block of the present invention, since natural stone is attached to the front surface of the concrete block, when used for retaining wall construction, etc., it is possible to make it look as if the natural stone was masonry in appearance, and Since the blocks can be stacked in the same manner, it is possible for even an unskilled person to easily carry out the retaining wall construction. Further, since the convex portion is formed on the upper surface of the block leg portion and the notch which is fitted to the convex portion on the upper surface is formed on the lower surface of the block leg portion, the stone-clad blocks can be stacked easily and accurately. It is also possible to prevent the piled stone blocks from shifting. Furthermore, a stone masonry block having an arbitrary front surface can be easily manufactured by attaching natural stones to the front surface of the block main body having an arbitrary shape, so that a variety of masonry patterns can be formed.

As shown in FIGS. 1 and 2, the concrete block 1 is a T-shaped member including a rectangular block main body 11 and a block leg 12 continuous to the rear surface (back surface) of the block main body 11. As shown in FIG. 3, the upper surface 12a and the lower surface 12b of the block leg portion 12 are configured to be flush with the upper surface 11a and the lower surface 11b of the block body portion 11, respectively. Further, near the rear portion of the upper surface 12a of the block leg portion 12, a convex portion 15 having substantially the same length as the width of the block leg portion 12 near the rear portion and having gradients on both sides in the length direction is formed. Formed in the direction.

In this embodiment, the upper and lower surfaces 12a and 12b of the block leg portion 12 are replaced by the upper and lower surfaces 11a and 11b of the block body portion 11.
The upper and lower surfaces are not necessarily flush with each other. However, as will be described later, it is preferable that the upper and lower surfaces of the block leg portion 12 and the block main body portion 11 are flush with each other as in the present embodiment from the viewpoint of easiness of stacking the stone-clad block A and the like. . Further, in the present embodiment, the convex portion 15 is formed near the rear portion of the upper surface 12a of the block leg portion 12, but the convex portion may be formed anywhere on the upper surface 12a of the block leg portion 12. However, it is preferable to form the convex portion 15 in the vicinity of the rear portion of the upper surface 12a as in the present embodiment from the viewpoint of preventing deviation when stacking the stone-clad blocks A on the inclined surface. Further, the convex portion 15 can be formed in the same direction as the central axis of the concrete block 1, but from the viewpoint of preventing misalignment, the forming direction of the convex portion 15 is the same as that of the block leg 12 as in this embodiment. The width direction is preferable. Further, in the present embodiment, the length of the convex portion 15 is set to be substantially the same as the width of the block leg portion 12 at the position where the convex portion 15 is formed, but the length of the convex portion 15 can be set freely, for example, The width may be smaller than the width of the block leg 12 near the rear of the upper surface 12a of the block leg 12. However, in order to stack the stone-clad block A easily and quickly, as in the present embodiment,
It is preferable that the length of 15 is substantially the same as the width of the block leg 12 at the position where the protrusion 15 is formed. On the other hand, the lower surface 12b of the block leg portion 12 is formed with a notch 16 that fits into the convex portion 15 of the upper surface 12a of the block leg portion 12. It should be noted that the convex portion and the concave portion may have any shape as long as they fit together.

The natural stone 3 is a plate-shaped stone material having a bottom surface having the same shape as the front surface (front surface) of the block main body 11, and granite oresite is mainly used. The same applies to the following examples. The natural stone 3 has the natural stone 3 as the lower surface,
Assemble a formwork of the same shape as the concrete block 1 to be produced, pour the ready-mixed concrete into the formwork, remove the formwork after the ready-mixed concrete has solidified, and remove the block body
Glue to 11. In this embodiment, the natural stone 3 is formed by driving the raw concrete into the bottom surface (back surface) of the natural stone 3.
Although the concrete block 1 and the concrete block 1 are integrated, any method can be adopted as long as the natural stone 3 can be firmly attached to the concrete block 1. For example, the natural stone 3 is attached to the front surface of the block body 11 by an adhesive. A method of bonding may be used. The same applies to the following embodiments.

Next, the case of stacking the stone-clad blocks A of this embodiment to construct a masonry retaining wall will be described with reference to FIG. In FIG. 4, A1 is a stone masonry block that has already been installed, A2 is a stone masonry block that is to be stacked on the stone masonry block A1, and A3 is a stone that is to be installed adjacent to the stone masonry block A1.

After that, the stone block blocks will be stacked in the same manner. Next, a small gap d is formed in the lateral direction of the stone-clad block A1.
And the stone-clad block A3 is placed. Then, similarly to the above, the stone-clad blocks are sequentially stacked. Thereafter, similarly, stone masonry blocks are sequentially arranged in the lateral direction. It should be noted that the gap d between the stone-clad blocks adjacent to each other in the lateral direction can be freely set, but the gap d allows the filling of the backfill concrete described later to be performed smoothly and the stone-clad blocks adjacent to each other in the lateral direction. It is preferable that a strong connection can be obtained by backfilling concrete between. Finally, the masonry blocks A1 and A that are laterally adjacent to each other
The back-filling concrete 7 is placed in the space formed between the side surfaces of the second block leg portion 12, the peripheral portion thereof, and the gap portion in which the gap d is formed. In addition, although the said Example is an explanation at the time of comprising a vertical retaining wall, an inclined retaining wall can be similarly comprised.
