PURPOSE:To raise the stability against external forces of a structure by a method of in which a free portion where the extension of anchors is allowed is formed in the way of the anchors buried under the ground, and the upper part of the free portion is fixed to the foundation of a structure. CONSTITUTION:The ground 2 in the supporting place of a structure 3 is excavated to a given depth, and bore holes 5 are drilled. A free portion 6a permitting the extension of anchor material is formed in the way of the anchor material by providing outserts 10 there. The anchors 6 are set in the bore holes 5, a grout 9 is packed into the bore holes 5, concrete for the foundation 1 is placed and hardened, and the ground 2 is embedded with soil. When a lifting force is applied to the foundation 1, the anchors 6 extend against the lifting force according to loads to be applied to the anchors 6 in the external fitting 10 surrounding the free portions 6a. |
