PROBLEM TO BE SOLVED: To provide an anchor which can not be easily pulled out when it is screwed in the ground and which can be easily pulled out by inserting an iron rod and turning it, by forming a hole in which the iron rod can be inserted, in the vicinity of one end side of a twisted band steel and slightly sharpening the other end to form the anchor. SOLUTION: A hole 2 in which an iron rod can be inserted is formed in the vicinity of one side end of a twisted band steel 1 formed by cutting a long twisted band steel, and the other end thereof is slightly sharpened so as to be easily stuck into the ground. The hole 2 in which the iron rod can be inserted is formed in the flat part of the twisted band steel 1 whose front end is twisted while leaving a part of the band steel as it is, and the front end of the twisted band is a little sharpened. When using this anchor, an appropriate iron rod is inserted in the hole 2, turned, and screwed in the ground, then, a rope is inserted in the hole 2 and tensed. In this way, it can be easily manufactured and a pile hard to pull out can be provided. Further, when pulling out the pile, the iron rod is inserted in the hole 2 and turned. Then, the pile can be easily pulled out. |
