Description

  The present invention relates to a suspension jig and a method for adjusting the inclination of a suspended body, and in particular, a suspended jig and a suspended body suitable for suspending a suspended body such as a reinforcing bar that is located at a position where the center of gravity is shifted from the center. The present invention relates to a tilt adjustment method for a suspended body.

  Conventionally, when a reinforcing bar is installed in the excavation groove provided on the ground at a construction site such as a building, the reinforcing bar is suspended from the hook of the crane via a wire, and the reinforcing bar is moved above the excavation groove by operating the crane. It is transported, and the reinforcing bar is lowered by the operation of the crane and installed in the excavation groove.

  In such rebar rod installation work, there is no particular problem if the center of gravity of the reinforcing rod is located at the center, but if the center of gravity is located at a position deviated from the center, When a reinforcing bar rod is suspended from a hook via a wire, the reinforcing rod rod is suspended in an inclined state. If the reinforcing bar rod is inserted into the excavation groove in this state, the reinforcing bar rod contacts the inner surface of the excavation groove. Occurs. For this reason, when the center of gravity of the reinforcing bar is deviated from the center, take measures such as adjusting the position of the wire that hangs on the reinforcing bar and using a lifting jig with a function to adjust the position of the center of gravity. There is a need.

  An example of this type of hanging jig is described in Patent Document 1. This suspension jig (balanced suspension jig) is provided with a sheave rotatably at a position slightly outside the center at both ends of the suspension beam, and a counterweight is attached to the sheave via the arm, and the base of the arm The wire is suspended from the sheave through the sheave, and the suspended load is suspended from the wire.

In the hanging jig having such a configuration, when the suspended load is suspended, the counterweight is lifted upward via the arm, so that even if the suspended load is lifted on one side, the counter The weight can keep the suspended load horizontal.
