PRESSURE RECEIVING PLATE FOR ANCHORING METHOD

摘要

PROBLEM TO BE SOLVED: To improve strength and rigidity of a pressure receiving plate for an anchoring method for radially extending a plurality of pressure receiving grounding plate parts from a central pressure receiving part by devising a shape of the pressure receiving grounding plate parts. SOLUTION: This pressure receiving plate for the anchoring method is composed of the central pressure receiving part 1 having a grounding bottom plate part 2 for freely grounding on a slope face and an anchor installing part (s) for inserting and locking an anchor member and a plurality of pressure receiving grounding plate parts 5 for radially extending toward the side from this central pressure receiving part 1. A center vertical rib 8 is integrally continuously arranged over the tip side of the pressure receiving grounding plate parts 5 from the anchor installing part (s) in a central area in a width in the respective pressure receiving grounding plate parts 5. The thickness of this center vertical rib 8 is set so as to become thick for approaching the anchor installing part (s). COPYRIGHT: (C)2004,JPO
