[Problem that the invention attempts to solve]

The conventional concrete blocks mentioned above have a limit to their own strength, and cannot be used in cases where excessive weight is applied or where excessive strength is required for the walls, such as in mid-rise or high-rise buildings. As for structural walls, even if the blocks were reinforced with reinforcing bars, there were problems in terms of strength. The use of blocks to form building walls has many advantages, such as being easily accomplished by block masonry and eliminating the need for on-site construction work such as temporary wooden frames. , the appearance of blocks as strong structures was expected.

Furthermore, when placing a plurality of reinforcing bars on a conventional block, it took time and effort to specify the positions of the reinforcing bars and temporarily fix them, resulting in poor workability.
Also, in the setting and demolding of the molding form in the manufacturing stage of conventional concrete blocks, especially in the formation of the cavity existing inside the block, there are There were also problems with mass production of blocks, such as the middle frame being difficult to remove.

This invention was made to solve the problems of the conventional concrete blocks mentioned above.
By arranging a steel plate inside the block and, especially in the case of the present invention, by providing reinforcing ribs or reinforcing bars on the steel plate, significant longitudinal reinforcement is automatically achieved when the block is loaded, and vertical reinforcement is not required separately. This eliminates the need for reinforcement work, significantly increases the strength of the block itself, simplifies the block masonry method, and makes the constructed block wall strong, expanding the range of applications for block structural walls. Another object of the present invention is to provide a concrete block that simplifies the process of forming a form, setting the form, and removing the form in the mass production stage of the block.

[Means for solving problems]

The above-mentioned problem arises in a concrete block consisting of two wall plates spaced apart from each other and one or more connecting plates connected between the wall plates. This problem is solved by a concrete block characterized in that an iron plate is disposed around the connecting plate and reinforcing ribs or reinforcing bars are provided on the iron plate.
