Claims

[Scope of Claim for Utility Model Registration] After a resistance plate 21 made of a rectangular steel plate curved into a vertically elongated regular arc shape is cast in advance, a stabilizing plate 31 made of a rectangular straight steel plate is cast afterwards, and both are connected underground. For stay anchors that at least have tensile strength. The pivoting part of the upper pull plate 5, which is the tensile force point of the resistance plate 1, is set on the direction plate 2 at a position near 13 from the upper end of the longitudinally stretched resistance plate 1, and the upper pull plate 5 has a vertically curved top. , the rear side part is rotated only in the curved inner arc surface side with the auxiliary plate 6, and the guide plate 10 is bent from the vertically upper middle side, and the direction plate 2 is bent only in the rear end part and rotates only inward. The bent upper part of the guide plate 10 and the auxiliary plate 6 are in a substantially parallel state without intersecting with each other.
Furthermore, the stabilizing plate support 4 is a single piece, greatly reducing the cutting resistance of the resistive plate 1 integrated with each member. The planar area of the stabilizing plate 12 that is subsequently placed is approximately twice the resistance 1, so that the resistance plate 1 immediately starts rotating from its tip due to the upward pulling load.
The stay anchor is characterized in that the stabilizer plate 12 begins to move in the horizontal pressure direction and exhibits a large tensile strength in the process.
