Installation structure of buried member and buried member

摘要

Problem to be solved: to provide a buried member and its installation structure capable of suppressing damage of the installation surface when a large external force is applied to the structure.Solution: a cylindrical wall portion is disposed outside the fastening portion, a gap portion is formed between the wall portion and the fastening portion, and the height position of the upper end of the wall portion is substantially aligned with the installation surface, and the lower end of the wall portion is positioned above the lower end of the fastening portion.When the height of the upper end of the wall portion is substantially coincident with the installation surface and the buried member is fixed and fixed, the upper surface of the filling material on the outer side of the wall portion and the upper surface of the filling material filling the inside of the wall portion are partitioned by the wall portion.As a result, when a large external force is applied to the structure installed in the installation surface and the force is transmitted to the fastening portion, cracks and cracks generated in the filling material in the gap portion in the vicinity of the fastening portion are prevented from being obstructed by the wall portion and difficult to reach the outside thereof, and the filling material on the exterior side of the wall portion, or the like is It is possible to suppress the damage of the installation surface outside the buried hole.Diagram
