Title (EN) ANCHORING MEMBER
(FR) PIECE D"ANCRAGE
Abstract: front page image
(EN)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.
(FR)Piece d"ancrage telle qu"un clou, une piece d"ancrage etc., renforcee fortement pour eviter l"extraction de la piece. La plupart des pieces d"ancrage conventionnelles de ce type sont formees avec des moyens pour eviter l"extraction de celles-ci, tels qu"une rainure en spirale, une rainure annulaire etc., a l"extremite de la base de son ancrage. De tels moyens ne sont pas suffisants pour empecher l"extraction de cette piece, et ne presentent pas d"effet d"ancrage lorsque la base d"ancrage est formee par un materiau poreux, mou, tel que du beton expanse. La piece d"ancrage selon l"invention consiste en une paire de pieces formant pieds (3), (3) faisant contact l"une avec l"autre en tant que partie d"ancrage (4) chaque pied (3) comprenant une surface taillee en pointe (7) formee a l"extremite du cote oppose. Lorsque cette piece est ancree, la partie d"ancrage des pieds (3), (3) est ancree dans le materiau de base et s"etend graduellement afin d"etre couplee au materiau de base afin de renforcer l"effort d"arret pour empecher le relachement de la piece.
