Abstract
Description
[Technical field]
[0001] The present invention relates to a tapered concrete block that can be connected without joints. [Background technology]
[0002] A proposal for a tapered concrete block that can be connected without joints. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2024-008456 A [Patent Document 2] JP 2024-007833 A [Patent Document 3] JP 2023-157360 A 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 started commercialization development. We have confirmed that the shape is easier to use, so we will file an additional application. [Means for solving the problem]
[0005] Concrete blocks 300mm to 500mm long And the shape Thickness:Width:Length Dimension ratio 2:4:8, At both ends on the center line in the length direction Thickness :Width:length ratio is 2 The shape is a cube with a U-shaped space arranged inside. Centered on the longitudinal centerline Thickness A cubic space with a width:length ratio of 2 is created to create a square-shaped Shape with space year, The concrete blocks are placed on the inside of the U-shaped structure at both ends. The outer circumference is made with a negative tolerance so that it can be inserted inside the central square. size In particular Uses a blended mortar for a smooth surface year, The four corners of the concrete block were tapered. The method according to claim 1 In tapered concrete blocks, The concrete block The space between the two concrete blocks is U-shaped at both ends or the central U-shaped space. By inserting one of the protruding parts into each other, the concrete blocks can be fixed without joints. Effect of the Invention
[0006] By checking the position of the arrow mark on the main body and the arrow mark on the cover by touching with your fingers, you can carefully position the screws. It became easier to fit it in without having to check it visually. [Brief description of the drawings]
[0007] [Figure 1] Figure 1 is a perspective view of a tapered concrete block that can be connected without joints. [Diagram 2] Figure 2 is a perspective view of concrete blocks that can be connected without joints. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] An embodiment of the present invention will be described with reference to FIGS.
[0009] FIG. 1 is a perspective view of a tapered concrete block that can be connected without joints.
[0010] FIG. 2 is a perspective view of concrete blocks that can be connected without joints. EXAMPLES
[0011] FIG. 1 is a representative diagram of the present invention. [Industrial Applicability]
[0012] They can be manufactured and sold as parts and materials 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, which is 4 / 2 of the total. 2. The thickness:width:length ratio of concrete blocks that can be connected without joints is 2:4:8, 2 / 2 of the applicable area 3A Tapered corners of concrete blocks that can be connected without joints 3B Section of concrete block before tapering the four corners so that they can be connected without joints 4 Angle θ for tapering the four corners
Claims
1. A concrete block with a length of 300mm to 500mm and a shape of thickness: Width: Length The dimension ratio is 2:4:8, and the thickness is: The width:length ratio is 2 The shape is a cube with a U-shaped space arranged inside. A cubic space with a thickness:width:length ratio of 2 is provided in the center of the longitudinal centerline, forming a square-shaped The concrete blocks are arranged in a shape with spaces between them, and the inside of the U-shaped blocks at both ends of each other, The outer circumference is specified with a negative tolerance dimension so that it can be inserted inside the central L-shaped part. Use a mortar mixture to create a smooth surface. The four corners of the concrete block are tapered. Tapered concrete blocks that can be connected without joints.
2. 2. The tapered concrete block according to claim 1, wherein the concrete block The concrete blocks are then fitted with concrete blocks that are shaped like a square or square. By inserting one of the protruding parts into the other, the concrete blocks can be fixed without any joints. A tapered concrete block that can be connected without joints.
