Conventionally, since the building blocks are buried and buried while being stacked, the building blocks are made of a stone having a heavy and durable shape so as to withstand the earth pressure applied from behind and to prevent collapse. Molded in concrete,
Therefore, it takes time and effort to use heavy equipment for transportation and construction to the site, and in the case of manual labor, it is a heavy labor job.

[0005] Recently, concrete construction blocks having a lightweight structure that is easy to handle have come to be proposed. Blocks have come to be required.

In some cases, it is required to change the pattern of the surface depending on the construction site from the viewpoint of aesthetics. It had to be stored and transported so as not to mix, which was troublesome. Further, there has been a demand for a hue different from that of general concrete products, such as a hue similar to a stone piling stone.

Further, depending on the construction site, it is required to bury a drainage pipe for discharging rainwater or the like that has infiltrated the land behind the construction site. It was a skillful and tedious job. The present invention can be easily handled and constructed even by non-experts by reducing the weight, and the surface pattern,
An object of the present invention is to provide a concrete building block capable of changing a hue.

[0008]

In order to achieve the above object, a construction block according to the present invention comprises a main block in which a regular hexagonal plate-like body is integrally formed in a drum shape so as to be symmetrical, and a main block. Surface divided in the connection direction by a line orthogonal to the opposite side of the regular hexagon on the surface of the surface of the main block, and a surface divided in the connection direction by a line connecting the opposite vertices of the regular hexagon on the surface of the main block and the sub-block forming a pentagon This problem can be solved by comprising a sub-block having a trapezoidal shape.

Further, the surface patterns of the two plate-like bodies are molded so as to have different patterns or hues, and two or more wall surface patterns are formed by one construction block.
The surface pattern may be formed by forming the surface forming portions of the two plate-shaped members of the mold frame into different patterns, and sand or coloring material having different hues may be applied to the opposite plate members. The used concrete may be injected and integrally molded.

Further, when integrally forming the plate-like body so as to be symmetrical via the connecting portion, a reinforcing bar is buried in the connecting portion so as to support the two plate-like members at both ends, and a metal wire is provided at the center of the reinforcing bar. It is wound or welded and protruded from the surface of the connecting portion to be integrally molded. The metal wire has a length that can be wound and fixed to an adjacent construction block or a reinforcing bar incorporated between the construction blocks for reinforcement, and a number wire used for construction is preferably used.

Further, a ready-made pipe is cut into a required length at a connecting portion of the plate-like body, and both ends of the pipe are located inside the surface of the plate-like body, and the pipe is covered with concrete of the plate-like body. And integrally molded. The pipe may be made of synthetic resin, iron, cast iron or the like, and the openings at both ends may be closed with paper or the like so that concrete does not flow in when the plate-like body is molded with concrete.

Further, the main block has a shape in which the surface shapes of the two plate-like bodies are stacked so that there is no gap between the plate-like bodies of the adjacent main blocks after the construction, that is, two opposite sides of a regular hexagon are formed. It is possible to form a hexagon different from the length of other equal four sides, or a square such as a square, rectangle, trapezoid, or rhombus, or a triangle such as an equilateral triangle or an isosceles triangle. According to the main block, the whole shape may be integrally formed so as to form a drum shape.
