Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used when a suspended object such as a building material or a civil engineering material is suspended and moved by a crane or the like, and one end thereof is attached to the suspended object. The present invention relates to a hanging jig that can be hooked with a crane hook or the like at its end.

[0002]

2. Description of the Related Art Since building materials and civil engineering materials are large or heavy, they are hung and moved by a crane or the like. In this case, conventionally, as shown in FIG. 7, a building material,
The insertion portion B at one end of the hook-shaped hook A made of a metal round bar is inserted and locked into the through hole 2 such as a bolt hole formed in the suspended body 1 such as a civil engineering material. The wire rope D is attached to the ring-shaped engaging portion C formed on the other end of the hook-shaped hook A, and the hook E of the crane is engaged with the wire rope D and lifted by the crane.

[0003]

The conventional hanging method using the hook type hook A has various problems as described below. As shown in FIG. 7, when the through holes 2 of the suspended object 1 are oriented laterally, the suspended objects 1 are arranged side by side as shown in FIG. 6B, and the suspended suspended objects 1 arranged side by side are penetrated. When a bolt is inserted into the hole 2 to connect it, the insertion portion B of the hook type hook A cannot be inserted into the through hole 2, and the suspended object 1 cannot be suspended using the through hole 2. There was a problem.

Since the hook-shaped hook A has the inserting portion B which is oriented laterally, it is difficult to insert it into the upward through hole F formed in the upper surface of the suspended body 1 as shown in FIG. 7B. Also, even if it can be inserted, the locking becomes unstable,
Since there is a risk that the hook-shaped hook A will come off during hanging, it was not possible in practice to insert the hook-type hook A into the upward hole F to hang it.

When the objects to be suspended 1 are arranged side by side as shown in FIG. 6 (a) and are stacked vertically, a through hole 2 on the side surface of the object to be suspended 1 is provided horizontally. Since it is closed by the hanging body 1, the hook type hook A cannot be inserted into the through hole 2 as it is. In this case, in order to insert the hook type hook A into the through hole 2 in the horizontal direction, the adjacent suspended object 1 is temporarily displaced laterally to form a gap S between the through hole 2 and the hook type hook from the gap. Since A must be inserted into the through hole 2, workability is extremely poor.

As shown in FIG. 6 (a), the hook-shaped hook A locked in the through hole 2 on the side surface of the suspended object 1 projects laterally from the side surface of the suspended object 1. ), Which are arranged side by side in several rows, and are stacked up and down in several steps 1
When moving one by one and moving it to another place as shown in FIG. 7B, a hook-shaped hook is placed next to the suspended object 1 arranged in advance when the suspended object 1 is subsequently dropped. A gets in the way. For this reason, it is necessary to open the suspended objects 1 arranged next to each other with a gap between them, and then to move the suspended objects 1 sideways and press them against the suspended objects 1 arranged in advance. The work was very troublesome.

As shown in FIG. 6 (a), since the hook-shaped hook A locked in the through hole 2 on the side surface of the suspended object 1 projects laterally from the side surface of the suspended object 1, in a narrow place. When performing a hanging operation, the hook type hook A may hit something else. In this case, since the hook-shaped hook A is only inserted into the through hole 2, there is a possibility that it will come off the through hole 2, which is very dangerous. Also, the object hit by the hook-shaped hook A may be damaged.

Since the hook-type hook A is simply inserted into the through hole 2, locking is unstable, and the hook-type hook A may be displaced when the suspended object 1 is suspended. Then, the balance of the suspended object 1 may be lost and the hook type hook A may be disengaged to cause a danger.

The object of the present invention is to vertically engage the suspended body 1 with the through hole 2 facing upward, and to lock it.
The insertion into the through hole 2 can be locked easily by a one-touch operation, and the locking is reliable, and the suspended object 1 is misaligned during suspension.
Does not incline, the locking does not disengage, and further, when it is locked in the through hole 2, it does not project to the side of the suspended object 1 and does not become an obstacle during lifting or hanging. , To provide a hanging jig that does not easily hit other objects.

[0010]
