大変面倒であった。Problems to be Solved by the Invention By the way, since the cylindrical anchor body of the above-mentioned expansion anchor is made by cutting a round bar material, the processing cost is high. Zunawara, a pin hole was cut into the round part, and the end was slotted to form an expandable skirt part, and a ring-shaped protrusion was generally added to the outer circumference of the skirt part. The rolling process and the rolling of the threaded part around the outer periphery of the anchor body were inevitable. In order to converge the pin holes at the inner depths, holes in two to four stages require machining, which is very troublesome.

分離できるから、施工後の取り外しか簡単にてきる。Effects of the Invention As described above, according to the present invention, the cylindrical anchor body 1 is divided into two parts along the axis, and a pair of divided pieces 2,
2, each divided piece 2 can be mass-produced at a low cost by die-casting, cold-forging, or shrugging without cutting, and can be mass-produced at a low cost. . Moreover, since both the divided pieces 2.2 are formed into a cylindrical shape with their upper end portions held by an annular joint such as a washer 6 and a nut 20, when the driving pin 7 is inserted and driven, Each divided piece 2 expands smoothly as a whole, and firmly and reliably adheres to the wall surface of the pilot hole, providing great strength for use. Moreover, since the divided pieces 2 are pushed open with a small force, the diameter of the driving pin 7 can be made thinner, and the thickness of the divided pieces 2 can be increased accordingly, thereby increasing the strength. Further, a driving pin 7 and a washer 6 which is an annular joint
If you remove the nut 2○, you can easily separate the two parts υ and 2, so you can easily remove it after construction.
