Method of forming guardrail by connecting base block for guardrail and base block for guardrail to adjacent base block in extension direction

摘要

[PROBLEMS] To easily place a foundation block at a predetermined bending arrangement position with respect to an adjacent foundation block, and to fill a padding such as mortar or concrete between the adjacent foundation blocks with a low cost connection means. The guardrails are connected to each other without being fixed and fixed between adjacent base blocks. SOLUTION: The position of adjacent base blocks is adjusted by placing one convex R-shaped surface or concave R-shaped surface and the other concave R-shaped surface or convex R-shape in contact engagement with each other, and a predetermined bending arrangement position is obtained. In the state where the filler is not inserted into the space between the side walls, the side walls of the adjacent base blocks are fastened and connected by two sets of fastening means, and adjacent to the arrangement at the predetermined bending arrangement position. Fix the side walls of the foundation block. [Selection] Figure 1
