Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material sling, and more particularly to a sling for safely hoisting a long material such as a steel frame with a suspension chain at a construction site of a building or the like.

For example, at the construction site of a building, a long material such as H-shaped steel is sometimes hung by a hanging tool and a hanging chain and moved.

In this type of material hoist, a tightening screw is provided on one leg of the U-shaped hoist body, and a U-shaped hanging part is fixed to the other leg or the connecting part between the legs, and the tightening screw is fixed. A long material such as a flat part of H-shaped steel is sandwiched between the tip and the other leg, a hanging chain is inserted through the hanging part, and the hanging tool is lifted by the hanging chain to hang the H-shaped steel. structure is known.

However, depending on the site conditions, when the material hoisting tool is attached to the H-shaped steel, the hanging part will be on the lower side of the H-shaped steel, making it difficult to hang the hanging chain on the hanging part or to hang it securely. was difficult.

On the other hand, a U-shaped suspension part is attached to the body of the sling so that it can rotate in a plane including the axis of the tightening screw, and the suspension part located on the lower side of the H-shaped steel is rotated upward or sideways. There has been proposed a material hoisting tool that allows a hoisting chain to be easily and reliably hung on a hoisting part by moving the hoisting chain (Patent Documents 1 and 2).

However, in the material hoisting tools described in Patent Documents 1 and 2, the hanging part is rotated around one axis, so the end of the H-shaped steel approaches or overlaps with the structure or other H-shaped steel. Therefore, even if the suspension part is rotated around the axis, the suspension chain cannot be properly hooked to the suspension part.

In view of the above problems, the present invention provides a material sling which can be easily and reliably attached to the end of the material regardless of the attitude of the end of the material so that a sling chain can be stably hooked. The challenge is to

Therefore, the material sling according to the present invention is a material sling used for hoisting a material with a sling chain. A fastening screw that is attached to one leg so as to be able to advance and retreat, and that tightens and holds the material between the tip that is screwed and the other leg, and a fastening screw that is provided at the connection portion of the base and moves in the first direction A guide portion having a guide hole formed by fixing both ends of a guide rod portion extending to the connecting portion is inserted into the guide hole of the guide portion and connected to the guide rod portion so as to be displaceable or slidable by the guide rod portion. a first ring portion inserted through and connected to the first ring portion, a second ring portion displaceable or slidable by the first ring portion; and a hook that is attached rotatably about an axis and on which a suspension chain can be hooked.

One of the features of the present invention is that a guide portion which is all or part of a ring shape is fixed to the connection portion of the U-shaped base, and the first ring portion is inserted through the guide hole of the guide portion and connected. (1) The second ring portion is inserted into and connected to the first ring portion, and the hook portion is attached to the second ring portion so as to be rotatable about the rotation axis.

As a result, the first ring portion can be displaced to an arbitrary angle or position with respect to the guide portion by the guide rod portion of the guide portion, or can be displaced to an arbitrary position while being displaced to an arbitrary angle. Slide, displace the second ring portion to an arbitrary angle with respect to this (displaced and slid or original state) first ring portion, displace to an arbitrary position, or displace to an arbitrary angle The hook portion can be slid to an arbitrary position in the state of being pulled, and further the hook portion can be rotated about the rotation axis with respect to the second ring portion (displaced and slid or in the original state). As a result of being able to be oriented in any direction and positioned at any position with respect to the shape base, the hoisting tool can be easily and securely fastened to the end of the material regardless of the posture of the end of the material. and the hook portion can be placed in a desired position or posture, so that the hanging chain can be easily and stably hooked on the hook portion.

In the above description, the hanging chain is hooked on the hook portion. Since it can be slid to any position in the displaced state, it is also possible to hook the suspension chain to this first ring portion.

That is, the material sling according to the present invention is a material sling used for hoisting a material with a sling chain. A fastening screw that is attached to one leg so as to be able to advance and retreat, and that tightens and holds the material between the tip that is screwed and the other leg, and a fastening screw that is provided at the connection portion of the base and moves in the first direction a guide portion having a guide hole formed by fixing both ends of a guide rod portion extending to the connecting portion, and a guide portion inserted into the guide hole and displaced or slid in the first direction by the guide rod portion and a first ring portion capable of hooking a hanging chain.

In the present invention (second invention), a second ring portion is inserted through and connected to the first ring portion so as to be displaceable or slidable by the first ring portion and capable of hooking the suspension chain. You can prepare.

Further, a hook rotatable around the rotation axis is further attached to the second ring portion, and the suspension chain can be hooked on the hook.

The hook may be of a simple ring shape, and is composed of a J-shaped hook body, a stopper that opens and closes between the base and tip of the hook body, and a spring member that biases the stopper in the closing direction. can also be configured.
