Title:
アンカーから受圧板への荷重伝達部構造
Document Type and Number:
Japanese Patent JP7041425
Kind Code:
B2
Abstract:
To provide a load transmission part structure from an anchor to a pressure plate which can achieve both accurate dispersion of a load transmitted from an anchor to the entire pressure receiving plate and optimization of an angle of a pressure receiving plate bottom surface and the anchor without increasing trouble in pressure receiving plate manufacturing work.SOLUTION: A load transmission part structure 10 from an anchor to a pressure receiving part in a slope stabilization system 1 includes: an anchor 2 embedded in a slope S in a state in which an anchor head part 12 is exposed; and a pressure receiving plate 3 having a receiving pedestal 20 on which the anchor head part 12 is placed, and a body part 4 for receiving a tensioning force of the anchor 2 with respect to a natural ground via the receiving pedestal 20. In the receiving pedestal 20, compression strength is larger than that of the body part 4 of the pressure receiving plate 3, and it has: a side wall part 21 in which an outside surface has a conical shape tapered in the natural ground direction; and a bottom wall part 22 formed as a spherical surface whose inside surface is a concave shape. The anchor head part 12 is formed as a convex spherical surface in which an outside surface has substantially the same curvature with respect to the concave spherical surface on the inside surface of the bottom wall part 22 of the receiving pedestal 20.SELECTED DRAWING: Figure 2
