In the block wall body of the present invention, the joint groove 7 of the lower block a is provided with an adhesive joint with the inorganic adhesive 11, and the downward projecting edge portion 8 of the upper block a is fitted into the concave groove 7 and is adjacent to the left and right. The horizontal groove 10 of one of the blocks a, a is fitted with the laterally projecting edge 10 of the other block a, and the lower end surface of the inner wall portion 5 of the inner bearing portion 3 of the upper block a and the lower step Mortar or concrete e is filled in the upper end surface of the inner wall portion 5 of the inner bearing portion 3 of the block a and the downward projecting edge portion 8 of the upper block a, and mortar or concrete e is filled therein, and the outer side of the upper block a is formed. A required lateral gap h is formed between the lower end surface of the decorative portion 4 and the upper end surface of the outer decorative portion 4 of the lower block a.
And a required vertical gap i is held between the left and right end surfaces of the outer decorative portion 4 of the blocks a, a that are adjacent to each other on the left and right.

[Action]

According to the present invention, it is a strong masonry structure that can firmly support the load at the inner proof portion, and the circumference of each block is reduced by the horizontal gap between the upper and lower blocks and the vertical gap between the left and right blocks. As a result, a block wall body rich in stereoscopic effect and solid feeling can be obtained.

【Example】

First, the building block a used in the present invention is first
This will be described with reference to FIGS. The building block a is made of ceramic porcelain, and the face shells 1 and 1 are connected to each other by connecting portions 2 and 2.
A vertical cavity b is formed between the two, and a vertical cavity b'is formed outside each of the connecting portions 2, 2. The face shells 1, 1 are an inner bearing portion 3 and an outer decorative portion 4
Consists of. 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 5 is lower than the lower end surfaces of the outer decorative portion 4 and the inner wall portion 5. A downward projecting edge portion 8 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 projects from the right end surfaces of the outer decorative portion 4 and the inner wall portion 5. A lateral protruding edge portion 10 is formed. The projecting length of the lateral projecting edge portion 10 is approximately three times the depth of the vertical groove 9. In order to construct the block wall A by the building block a having the above structure, the block a is placed on the required foundation by an appropriate vertical cavity b,
A desired stacking method such as a tear joint or a potato joint shown in FIG. 4 is adopted while passing the vertical reinforcing bar c through b ', and at this time, the inorganic adhesive 11 is applied to the concave groove 7 of the lower block a. Is applied, and the downward projecting edge portion 8 of the upper block a is fitted into the concave groove 7, and the lateral projecting edge portion 10 of one block a of the blocks a, a adjacent to the left and right is connected to the other block. Fit in the vertical groove 9 of a and stack. In the above, for example, the connecting portion of every other block a
The horizontal rebar d is placed on the side of 2,2. After that, mortar or concrete e is placed between the face shells 1 and 1 of the block a, and not only the vertical cavities b and b ′, but also the lower end face of the inner wall portion 5 of the inner bearing portion 3 of the upper block a and the lower stage. An inward lateral concave portion f formed by the upper end surface of the inner wall portion 5 of the inner bearing portion 3 of the block a and the downward projecting edge portion 8 of the upper block a, and blocks adjacent to each other on the left and right sides.
The mortar or concrete is also filled into the inward vertical concave portions g formed by the left and right end surfaces of the inner wall portion 5 of the inner bearing portion 3 of a and a and the lateral protruding edge portion 10 so as to be surrounded. By this, the desired block wall A can be constructed, but this block wall A is composed of the upper and lower blocks a,
Since the space between a is the adhesive joint for applying the inorganic adhesive 11,
The workability is better than that of the conventional mortar joint, and the upper surface of the outer wall portion 6 of the inner proof portion 3 to which the inorganic adhesive 11 is applied, that is, the dimensional accuracy of the concave groove 7 is ensured. The fact that the coating surface can be reduced contributes to the improvement of the finishing accuracy of the coating surface of the block a. The adhesive joint is provided on the upper surface of the outer wall portion 6 of the inner bearing portion 3 of the lower block a, in other words, on the groove 7.
The lower end surface of the inner wall portion 5 of the inner bearing portion 3 of the upper block a, the upper end surface of the inner wall portion 5 of the inner bearing portion 3 of the lower block a, and the downward projecting edge portion 8 of the upper block a are inwardly laterally recessed. f
Is surrounded by mortar or concrete e as described above. Therefore, in the structural calculation of the joint, it can be treated that the load acts on both the inner wall portion 5 and the outer wall portion 6, that is, the entire width of the inner bearing portion 3. Further, since the protruding length of the downward projecting edge portion 8 projecting from the lower end surface of the concave groove 7 formed on the upper end surface of the face shell 1, 1 of the block a is about 2.5 times, A required lateral gap h (10 mm) is held between the lower end surface and the upper end surface of the outer decorative portion 4 of the lower blocks a, a. Moreover, since the protruding length of the lateral projecting edge portion 10 projecting from the right end surface is approximately three times the depth of the vertical groove 9 formed on the left end surface of the face shells 1, 1, the blocks a, which are adjacent to the left and right sides, A required vertical gap i (10 m
hold m).

【The invention's effect】

As is clear from the above description, according to the present invention, a strong masonry structure capable of firmly supporting a load by the inner load bearing portion, and a lateral gap between the upper and lower blocks and the left and right blocks are provided. By forming an empty joint around each block by the vertical gap between them, a block wall body rich in three-dimensional feeling and solid feeling can be obtained.
