<p>An anchoring member such as a nail, an anchoring piece, etc. reinforced with force for preventing the extraction of the member. Most of the conventional anchoring members of this type are formed with means for preventing the extraction of the member such as a spiral groove, annular groove, etc. at the base end of its anchor. Such means cannot sufficiently stop the extraction of the member, nor do they exhibit the anchoring effect in a case where the anchoring base is made of porous soft material such as foamed concrete. The anchoring member of this invention consists of a pair of leg pieces (3), (3) making contact with each other as an anchoring portion (4), each leg piece (3) including a tapered surface (7) formed at the end of the opposite side. When this member is anchored, the anchoring portion of the leg pieces (3), (3) is anchored into the base material and spread gradually to be coupled into the base material so as to strengthen the force for stopping the release of the member. </p> |
