AI Technical Summary
Existing concrete blocks face issues with uneven stacking due to displacement and require additional components that increase cost and complicate installation, especially at corners.
Utilizing three types of connecting hardware and hall-in anchors to secure the first-stage concrete block to the foundation, followed by installing two types of connecting hardware on each subsequent stage, ensuring alignment and stability without obstacles.
Ensures safe and obstacle-free installation of concrete blocks by maintaining alignment and preventing displacement, reducing the need for cutting and simplifying the installation process.

Abstract
Description
Technical Field
[0001] The present invention relates to a concrete block 1 suitable for preventing the left and right, up and down of the concrete block 1 from becoming uneven when constructing while stacking the concrete block 1 on the foundation 7.
Background Art
[0002] As this type of concrete block 1, a concrete block 1 related to the proposal of the applicant is known.
[0003] However, the connecting block 1 according to Non-Patent Document 1 requires a block different from the concrete block, which is not a convenient specification, increases the cost of the connecting block 1, and on the other hand, when filling the cavity of the concrete block with mortar, the connecting block 1 becomes an obstacle. In addition, when installing the connecting block 1 at the corner of the outside and the corner of the inside, there are problems such as the need to cut a part of the side wall of the block so that the connecting block 1 can be attached.

Summary of the Invention
Problems to be Solved by the Invention
[0005] The present invention can prevent the displacement in the vertical and horizontal directions of the concrete block while solving the problems of the above-mentioned connecting block 1 stack.
Means for Solving the Problems
[0006] In the present invention, in order to install the concrete block (1) on the foundation top end (7) without causing displacement or dimensional errors, three types of (2), (3), (4) connecting hardware for blocks and hall-in anchors are used to enable installation according to the design drawing. After the concrete block (1) is almost installed as per the drawing, two types of (5), (6) connecting hardware for blocks are installed on the upper surface of the first-stage block, and then the blocks from the second stage onwards are installed, thereby solving the above problems.
Effect of the Invention
[0007] In the present invention, according to the invention described in claim 1, the first-stage concrete block 1 must be fixed to the foundation top end 7 as per the design drawing. For this purpose, three types of connecting hardware 2, 3, 4 in claim 1 are installed by hall-in anchors. For the second stage and subsequent stages, two types of connecting hardware 5, 6 in claim 2 are installed on the upper surface of the first stage, and the second-stage concrete block 1 is installed. Thereafter, for the blocks from the third stage onwards, the concrete block 1 is installed in the same manner as the second stage while using the two types of connecting hardware 5, 6. By repeating this operation, the concrete block 1 can be installed more safely and without obstacles.
Brief Explanation of the Drawings

Figure 1
Figure 2
[0009] As shown in Fig. 1, the base top connecting metal fittings 2, 3, 4 of the present invention are respectively attached to the base top 7 of the structure at the necessary locations with through anchors, and further, vertical reinforcing bars 8 are welded to the inserted bars 9 that have already been provided. Then, while inserting the vertical reinforcing bars 8 welded to the hollow part of the concrete block 1, concrete paste is applied, and while aligning with the respective connecting metal fittings 2, 3, 4, when the first stage is completed, after filling the mortar to half of the concrete block 1 and hardening it, horizontal reinforcing bars are installed. The second stage is also carried out in the same manner, installing the concrete block 1 and the necessary connecting metal fittings 5, 6 in alignment with the joint of the first stage. Then, the second-stage concrete block 1 is stacked while aligning with the concrete paste and the connecting metal fittings 5, 6 that have already been provided, and horizontal reinforcing bars are also installed. This process is repeated up to the necessary number of stages while leaving a welding margin for the vertical reinforcing bars 8. Due to the function of the connecting metal fittings and the concrete paste, the concrete block 1 stands independently even before filling the mortar. After that, the mortar is filled to half of the last stacked block and waits for hardening, and then the stacking of the next block begins. This process is repeated several times to stack the blocks up to the necessary number of stages. The components are the concrete block 1, the base top connecting metal fittings 2, 3, 4, and the connecting metal fittings 5, 6.

Claims
1. The connecting hardware (2), (3), (4) for installing and placing the first-stage concrete block (1) at the construction site is attached to the required locations of the foundation top end (7) with a hold-in anchor.
2. The concrete blocks (1) from the second stage onwards are connected with the connecting hardware (5), (6) and concrete paste so as not to cause displacement between the left-right and up-down concrete blocks (1).
