[Problems to be Solved by the Invention]

However, the shortage of manpower has recently become more serious, and it is not easy to secure craftsmen. Moreover, even if, for example, it is discovered that the block walls that have been masonry-constructed have unevenness, especially on the inner and outer surfaces (or front and rear surfaces) that are vertical surfaces, it is no longer possible to correct the unevenness. It was Further, in general, the block wall body is such that the outer surface of each block and the mortar joint are substantially flush with each other, which is rather monotonous. The present invention simply stacks the blocks of each stage without interposing mortar or the like, and after properly correcting the unevenness of the inner and outer surfaces,
By injecting an inorganic adhesive inside the joints of each step, the portions can be fixed so that even an amateur can easily construct the desired block wall, and the outer joints of each block are emptied. It was proposed for the purpose of obtaining a high-quality block wall body in which a three-dimensional effect is exhibited by using joints.

That is, the building block a is made of ceramic porcelain, and the face shells 1 and 1 are connected by the connecting portions 2 and 2, and a vertical cavity b is formed between these connecting portions 2 and 2. Vertical cavities b ′ and b ′ are formed on the outer side of 2. The face shells 1, 1 are composed of an inner bearing portion 3 and an outer decorative portion 4. Further, the inner bearing portion 3 is composed of an inner wall portion 5 and an outer wall portion 6, and the outer wall portion 6 is a portion located between the outer decorative portion 4 and the inner wall portion 5. The upper end of the outer wall portion 6 is lower than the upper end surfaces of the outer decorative portion 4 and the inner wall portion 5, and a concave groove 7 is formed therein, and the lower end of the outer wall portion 6 has lower end surfaces of the outer decorative portion 4 and the inner wall portion 5. A downward projecting edge portion 8 that projects further is formed. The protruding length of the downward protruding edge portion 8 is approximately 2.5 times the depth of the concave groove 7. The left end of the outer wall portion 6 is set back from the left end surfaces of the outer decorative portion 4 and the inner wall portion 5 to form a vertical groove 9 therein, and the right end is the right end surface of the outer decorative portion 4 and the inner wall portion 5. A lateral protruding edge portion 10 that projects further is formed. This side edge 10
The projecting length of is approximately three times the depth of the vertical groove 9. For constructing the block wall A by the building block a having the above-mentioned structure, for example, the block a is passed through appropriate vertical cavities b and b'through vertical reinforcing bars c on a required foundation, for example, a tear joint or a potato shown in FIG. It is constructed by adopting a desired stacking method such as joints, and at this time, the downward projecting edge portion 8 of the upper block a is fitted into the concave groove 7 of the lower block a, and The lateral protruding edge portion 10 of one of the blocks a is fitted into the vertical groove 9 of the other block a and stacked. Each of the stacked blocks a is manufactured with high precision in the above-mentioned configuration, so that the steps are horizontal and the inner and outer surfaces (or front and rear surfaces) are simply fitted by sequentially fitting the corresponding portions as described above. Surface) is made almost vertical, but if there is an ingress or egress, that is, unevenness on the inner and outer surfaces, it is corrected as necessary. In this case, since each block a is not fixed with mortar or the like unlike the conventional block, the unevenness can be easily corrected. Looking at the state where the blocks a are simply stacked in this way, as described above, the downward projection protruding from the lower end surface of the concave groove 7 formed in the upper end surfaces of the face shells 1 and 1 of the block a as described above. The protruding length of the edge 8 is approximately 2.5
