Abstract

PROBLEM TO BE SOLVED: To provide a fastener attachable to a heavy object in a stable state at all times, facilitating attaching to and detaching from the heavy object, and simplifying constitution so as to be formed at a low cost. SOLUTION: This fastener is provided with a cylindrical member 3 fitted onto the head portion side outer periphery of a bolt with head in a state where movement in the axial direction is limited and having a flange portion on an abutting side onto the heavy matter, and an engage member 4 having the cylindrical portion 4a fitting onto the outer periphery of the cylindrical member 3 and having a rise portion rising from the end ridge in the outer diameter direction of the cylindrical portion 4a and provided with an engage hole 8. The axial direction length of the engage member 4 cylindrical portion 4a is set to be shorter than the axial direction length of the cylindrical member 3, and the engage member 4 is fitted onto the outer peripheral face of the cylindrical member 3 so as to be free in turning. For example a protrusion 6 protruding toward the center axis direction is formed on the cylindrical member 3, and the protrusion is pressure touched to the cylindrical non-screw portion of a bolt formed of a rolled bolt so that the movement in the bolt axial direction of the cylindrical member 3 is limited.

は限らず円環部５１ａが斜めに傾くことが多い。However, in the method of lifting the concrete molded product 52 with the eyebolts 51, it is difficult to always attach the eyebolt 51 as a stopper to the concrete molded product 52 in a stable state. At the same time, there is a problem that the work of attaching and detaching the eyebolt 51 to and from the concrete molded product 52 is troublesome. That is, when attaching the eye bolt 51 to the concrete molded product 52,
Even if the male screw portion 51b is screwed into the female screw hole 50a of the insert 50 up to its root, the annular portion 51a of the eyebolt 51 does not always face up and down as shown in FIG. Often tilted obliquely.

Since 0a is usually a right-handed screw, when the concrete molded product 52 is lifted, if the annular portion 51a of the eyebolt 51 screwed into the insert 50 is inclined rightward,
If the eyebolt 51 rotates counterclockwise and loosens due to the load of the concrete molded product 52, and if the annular portion 51a of the eyebolt 51 is inclined to the left, the eyebolt 51 rotates clockwise and is further screwed into the insert 50. It is.

The eyebolt 51 is always screwed into the insert 50 with an appropriate torque due to loosening or screwing of the insert 50 into the female screw hole 50a (predetermined screwing amount).
When the concrete molded product 52 is lifted, for example, when the eyebolt 51 is further screwed in, the male screw portion 51b of the eyebolt 51 is excessively inserted into the female screw hole 50a of the insert 50 due to a strong lifting load. And the work of removing the eyebolt 51 after the completion of the lifting work becomes very troublesome. In addition, this problem is caused even if the partner to which the eyebolt 51 is screwed is not the female screw hole 50a of the insert 50 buried in the concrete molded product 52, but the female screw hole provided in a heavy material such as a steel material. The same is true.
