Jointless connectable tapered concrete blocks

Abstract

Although the application of Japanese Patent Application No. 083640 / 2024 was evaluated, a more convenient shape could be confirmed at the stage of commercialization and development, and thus an additional application is filed.SOLUTION: A shape of a concrete block connectable without a joint is formed in a plan view shape, and four corners are formed in a tapered shape.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to tapered concrete blocks that can be connected without joints. [Background technology]

[0002] A proposal for tapered concrete blocks that can be connected without joints. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-008456 [Patent Document 2] JP 2024-007833 A [Patent Document 3] Japanese Patent Application Laid-Open No. 2023-157360 Summary of the Invention [Problem to be solved by the invention]

[0004] The patent application No. 2024-083640 has been approved, but we have just begun commercial development. We have confirmed that the shape is easier to use, so we will file an additional application. [Means for solving the problem]

[0005] Claim 1: A concrete block of 300mm to 500mm in length with a thickness:width:length ratio of 1 / 4" to 1 / 4". A cubic space with a height:width:length ratio of 2 is provided on both ends of the center line at a ratio of 2:4:8. A square-shaped space is created in the center of the U-shaped space with a cubic space with a height:width:length ratio of 2. The concrete blocks are placed in a mold, and the inside of the U-shaped part at both ends of each other, The outer periphery has a specific minus tolerance shape so that it can be inserted inside the central square-shaped part. The mortar used to create a smooth surface A concrete block that can be connected without joints. The shape of claim 1 is used to determine the combination direction of the concrete blocks. The concrete block has a U-shaped space at both ends or a square-shaped space in the center. Insert one of the protruding parts of the U-shaped part on each end of the two concrete blocks. This allows concrete blocks to be fixed without joints. Concrete blocks that can be connected without joints. However, the combination direction of the concrete blocks The concrete block has a U-shaped space at both ends or a square-shaped space in the center. Insert one of the protruding parts of the U-shaped part on each end of the two concrete blocks. In order to improve work efficiency and ease of use, Concrete block shape with thickness:width:length dimension ratio A cubic space with a height:width:length ratio of 2 is provided on both ends of the center line at a ratio of 2:4:8. A square-shaped space is created in the center of the U-shaped space with a cubic space with a height:width:length ratio of 2. The shape of the connector is maintained and the fixed part is secured when inserted. The shape of concrete blocks that can be connected without joints is shown in plan view. The four corners are tapered, allowing for joint-free connection. Concrete block tapered type. [Effects of the Invention]

[0006] By checking the position of the arrow mark on the body and the arrow mark on the cover with your fingers, you can carefully position the screws. It can now be easily fitted without visual confirmation. [Brief explanation of the drawings]

[0011] FIG. 1 is a representative diagram of the present invention. [Industrial Applicability]

[0012] It can be manufactured and sold as a component or material for DIY or low-stress fences. [Explanation of symbols]

[0013] 1. The thickness:width:length ratio of concrete blocks that can be connected without joints is 2:4:8, and the corresponding part is 4 / 2. 2. The thickness:width:length ratio of concrete blocks that can be connected without joints is 2:4:8, and the corresponding part is 2 / 2. 3A Tapered corners of concrete blocks that can be connected without joints 3B: The section of the concrete block that can be connected without joints before the four corners are tapered 4 Angle θ for tapering the four corners

Claims

[Claim 1] Prior patent application No. 2024-083640 Claim 1: A concrete block with a length of 300 mm to 500 mm and a thickness of: Width:length ratio Height: 2:4:8 on both ends of the center line Create a cubic space with a width to length ratio of 2. U-shaped, height in the center: A cubic space with a width to length ratio of 2 is created to create a square-shaped space. The concrete blocks are placed in a mold, and the inside of the U-shaped part at both ends of each other, The outer periphery has a specific minus tolerance shape so that it can be inserted inside the central square-shaped part. The mortar used to create a smooth surface A concrete block that can be connected without joints. Utilizing the shape of claim 1, the combination direction of the concrete blocks is The concrete block has a U-shaped space at both ends or a square-shaped space in the center. Insert one of the protruding parts of the U-shaped part on each end of the two concrete blocks. This allows concrete blocks to be fixed without joints. Concrete blocks that can be connected without joints. However, the combination direction of the concrete blocks The concrete block has a U-shaped space at both ends or a square-shaped space in the center. Insert one of the protruding parts of the U-shaped part on each end of the two concrete blocks. In order to improve work efficiency and ease of use, Concrete block shape with thickness:width:length ratio Height: 2:4:8 on both ends of the center line Create a cubic space with a width to length ratio of 2. U-shaped, height in the center: A cubic space with a width to length ratio of 2 is created to create a square-shaped space. The shape of the connector is maintained and the fixed part is secured when inserted. The shape of concrete blocks that can be connected without joints is shown in plan view.
