<P>PROBLEM TO BE SOLVED: To provide an inexpensive anchor by little manhour and an anchor construction method. <P>SOLUTION: In construction of a metal anchor 10, a hook part 14 is hooked about a metal wire (a base 104); by hitting the hook part 14, an anchor part 12 is stricken into a hole 102a of a stone material 102. Here, the hook part 14 is hit against a surface of the stone material 102 to deform the loop shape of a loop 14a in a closing manner so that the hook 14 winds about the wire net more tightly. Consequently, the wire net (the base 104) and the stone material 102 are tightly fastened through the metal anchor 10. Only one hole 102a is required to be bored in the stone material 102 for one metal anchor 10; therefore, an increase of manhour in boring can be avoided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
