Claims

[Scope of utility model registration request]

(1) Consisting of a male side hanging hardware and a female side hanging hardware, the male side hanging hardware includes a round shaft having a hook attachment part at the upper end to which a speculator hook can be freely attached and detached, and the outer periphery of the lower end of this round shaft. The female hanging hardware is provided with an outwardly protruding annular portion formed integrally with the round shaft and projecting at a plurality of positions perpendicularly symmetrical to the central axis thereof, and the female hanging hardware is fitted with a lower end of the male hanging hardware. A cylindrical body portion having an inner hole that is rotatable about a central axis, and a male hanging hardware that is placed opposite to a female hanging hardware with the central axis on an upward extension of the central axis of the female hanging hardware. When rotating about the central axis, the lower end of the male hanging hardware can be inserted freely in the direction of the central axis at a specific rotation angle position, and at a specific rotation angle position different from the above-mentioned position, the externally protruding portion annular A plurality of inwardly protruding annular parts overlapping the upper surface of the part and preventing the lower end of the male hanging hardware from being pulled out upwardly protrude inwardly from the surrounding wall, and a receiving part having a predetermined radiation shielding effect. A bottom wall having a certain thickness is integrally formed with the receiving seat portion and the bottom wall as upper and lower ends, and is embedded and fixed in the structure to be lifted so that its upper surface can be exposed, and the male side hanging hardware and A metal fitting for lifting a structure, wherein the female side lifting metal fittings are provided with a connecting structure portion for releasably connecting them to each other.

(2) The hook attachment part is fixed to the round shaft by passing through a slotted groove cut in the direction of the center axis of the upper end of the round shaft, crossing this slot and inserting the round shaft at right angles to the center axis. A metal fitting for lifting a structure according to claim 1, which is characterized by comprising a pin shaft.

(3) The coupling structure includes a keyway recessed along the radial direction on either the upper surface of the annular portion of the outwardly protruding portion and the lower surface of the annular portion of the inwardly protruding portion, and a keyway recessed along the radial direction on the other side. A metal fitting for lifting a structure according to claim 1 or 2, characterized in that it comprises a key-shaped part that is curved and has a shape that can be fitted into the key groove.

(4) The coupling structure includes a pin hole vertically penetrating each of the inwardly protruding annular portion and the outwardly protruding annular portion, and the overlapping inwardly protruding annular portion and outwardly protruding annular portion. and a pin shaft inserted through the pin hole, and the pin shaft is attached to the round shaft of the male side metal fitting via a drop string.
A metal fitting for lifting the structure described in item 1 or 2.
