摘要： PROBLEM TO BE SOLVED: To provide a slinging implement for a concrete product capable of reducing a size by simplifying the shape of the inserting hole of a fixing member. SOLUTION: A reduced diameter part 13b is provided at the tip part of a shaft main body 13a forming a shaft body 13, and a locking projection 13c of approximately the same dimension as the outside diameter of the shaft main body 13a is formed integrally with the tip part of the reduced diameter part 13b. On the other hand, an insert hole 21a of a fixing member main body 21 buried in a concrete product C is formed in a cylindrical shape having generally the same outside diameter as that of the shaft main body 13a, a fitting hole 21b is formed in the inner edge of the inserting hole 21a, and an extraction stopping body 22 is fitted fixedly to the fitting hole. The locking projection 13c is inserted from the opening 22a of the extraction stopping body 22 and rotated so as to lock the locking projection 13c to a locking groove 22b.

摘要： PROBLEM TO BE SOLVED: To provide a suspended sling for a concrete product capable of easily being manufactured by simplifying a structure, easily performing a detaching operation for the concrete product and easily visualizing a locking state. SOLUTION: A shaft part 13a of a supporting pin 13 is passed through insertion holes 12c, 12d formed at both of left and right end parts 12a, 12b of a shackle 12. At a tip part of the shaft part 13a, a cutout groove 13c is provided. Within the groove 13c, a falling prevention pin 14 is freely rotatably connected by a spindle 15. In a sate that the falling prevention pin 14 is along the shaft part 13a, the shaft part 13a is passed trough a locking hole 22a of an insert locking tool 22. Between the left and part 12a of the shackle 12 and a stop ring 16 locked on an outer periphery of the shaft part 13a, a coil spring 18 is interposed. A side wall of the left end part 12a of the shackle 12 is pressed on a side wall of a concrete product 21. The falling prevention pin 14 rotated at a locking position is pressed on a side wall surface of the concrete product 21.

摘要： PROBLEM TO BE SOLVED: To provide a fixing member of a concrete product C capable of reducing the number of parts to facilitate the manufacture and assembly work and reducing cost. SOLUTION: Lifting force holding parts 13b, 13c are integrally formed on an inner face of a housing cylindrical part 13a of the fixing member 13. Locking recessed parts 13d, 13e are formed on a lower face side of the lifting force holding parts 13b, 13c. A leaving prevention projection 13j is integrally formed on an outer peripheral face of the housing cylindrical part 13a. The whole fixing member 13 is integrally formed by synthetic resin. When a length in the axial direction of the lifting force holding parts 13b, 13c is L1, a length in the direction of axial line of an insertion hole 131 is L2, and the whole length of the housing cylindrical part 13a is L1+L2, dimensional ratio R=L1/(L1+L2) is set to R=0.28 to 0.67.

摘要： PROBLEM TO BE SOLVED: To provide a lifting attachment for a concrete product, preventing the removal of a washer and a coil spring from a middle portion of a shaft body and facilitating the attachment/detachment to/from a fixing member. SOLUTION: A locking protrusion 13c is provided at an end of the shaft body 13a via a diameter shrunk portion 13b. An extraction preventer 22 having an opening 22a through which the locking protrusion 13c can be inserted is provided near the inner end of the fixing member 11. An extraction preventing portion 22b is provided on the back of the extraction preventer 22 for preventing the locking protrusion 13c turned a predetermined angle around the axis of a shaft 13 from being extracted from the opening 22a. A circular ring 14A as a separate member is connected to the base end of the shaft body 13a, and a stepped portion 13k is formed at a middle portion of the shaft body 13a and a small diameter portion 131 is formed between the stepped portion 13k and the ring 14A. The coil spring 15 is laid between the washer 32 locked to the stepped portion 13k and the ring 14A.

摘要： PROBLEM TO BE SOLVED: To provide an insert with a female screw for a concrete product, an insert that facilitates attaching/detaching operation of a screw tool. SOLUTION: The insert with a female screw for a concrete product includes a resin-made insert body 10 that is provided with an insert hole 11 and imbedded into a concrete product C, with an opening of one end of the insert hole 11 facing outside. On the other end in the inner circumference of the insert hole 11, a female screw part 15 having a thread is provided and, on one end closer than the female screw part 15 in the inner circumference of the insert hole 11, a non-screw part 12 having no thread is provided. The length L5 in the axial direction of the female screw part 15 is set shorter than a half of the entire length L of the insert hole 11. The non-screw part 12 has an inner diameter that becomes smaller from one end to the other end, with the smallest inner diameter thereof is set equal to or larger than the valley bottom diameter D5 of the female screw part 15, which is the characteristic of this insert.
