Description of the Related Art Conventionally, in a construction site or the like, when lifting an iron plate or the like, a hook or the like at a tip portion of a crane or the like is hooked into a hole of the iron plate or the like opened with oxygen or the like, and then the crane is moved. When activated, an iron plate or the like is lifted and moved to a predetermined position.

However, in this method, when the hook is weakly caught or when another material hits the hook catching the iron plate, the hook comes off from the hole of the iron plate, and there is a danger to the worker. It is possible.

Therefore, recently, a method of directly hooking a crane or the like into the hole of such an iron plate has not been performed. As shown in FIG. 15, clamps 22 are attached to three to four or more or more portions of the iron plate 21. Thereafter, the clamp is lifted by a crane 23 via a wire or the like.

[0005]

However, when lifting an iron plate or the like using a clamp, unlike when directly hooking a hook at the tip of a crane into a hole in the iron plate, the clamp is first attached to the iron plate using a bolt or the like. A work for mounting and fixing is required, and a preparation work for mounting and fixing the clamp takes time, and the work is troublesome.

Further, even after the iron plate is moved to a predetermined position, the hook at the tip of the crane must be released from the clamp, and then the clamp must be further released from the iron plate. In addition, there is a problem that a storage place for clamps and bolts when not in use is required.

On the other hand, as described above, the method of directly lifting an iron plate with a crane involves a danger to workers and the like.
At this stage, we have to use clamps,
Therefore, means for solving such a problem has been desired.

Therefore, the present invention provides a method for building
An object of the present invention is to provide a hanger capable of safely and reliably lifting or hanging an iron plate or the like without increasing the number of work steps.

[0009]

A hanging bracket according to the present invention is a hanging bracket used for lifting or hanging an iron plate or the like at a building site or the like, and is formed continuously with a hollow portion and the hollow portion. And a stopper handle rotatably supported in the hanging metal body, and a stopper rotatably supported by the lower end of the hanging metal body. By lowering the stopper handle, the stopper can be fixed in a direction substantially perpendicular to the longitudinal direction of the hanging bracket main body.

[0010] When using the hanging member of the present invention, the hanging member of the present invention is inserted into a hole of an iron plate or the like until a stopper pivotally supported at the lower end of the hanging member main body penetrates the iron plate. By lowering the handle, the stopper is fixed in a direction substantially perpendicular to the longitudinal direction of the hanging member main body so that the hanging member of the present invention does not fall out of the hole of the iron plate. Then, thereafter, the hanging fitting of the present invention is lifted by a crane or the like.

[0011] As described above, in the hanging fitting of the present invention, an iron plate or the like can be lifted without using a clamp, so that the number of working steps is not increased.

After inserting the hanging member of the present invention until the stopper penetrates the iron plate, the stopper handle is lowered, so that the stopper is substantially perpendicular to the longitudinal direction of the hanging member body inserted into the hole of the iron plate or the like. Direction, so that the hanging metal body does not come off from the iron plate, so that the hanging metal does not come off from the iron plate during the lifting of the iron plate, etc., and the iron plate, etc. can be reliably lifted by the crane. It is possible and no danger to the operator.

A stopper handle is supported in a hanging metal body having a lever guide to be movable up and down.

A stopper is rotatably supported at the lower end of the hanging member main body, and the stopper can be fixed substantially vertically to the hanging member main body by lowering the stopper handle. .

Here, the stopper handle may be supported in the suspension fitting main body by a spring, and the stopper handle may be raised in a normal state. In the hanging fitting of the present invention, by lowering the stopper handle, the stopper can be fixed in a substantially vertical direction with respect to the hanging fitting main body so that the iron plate or the like can be lifted safely and securely. It is not necessary to fix the stopper in the direction substantially perpendicular to the hanging fitting main body. Rather, it is desirable that the stopper be parallel to the hanging fitting main body in consideration of storage and the like. Therefore, the stopper handle is supported by the spring inside the hanging fitting main body, and in a normal state, the stopper handle is raised so that the stopper is substantially perpendicular to the hanging fitting main body when not in use. Can be effectively prevented.

A spring is provided at the upper end of the stopper handle so that the stopper handle is pressed downward by the spring so as to oppose the elastic force of the spring when the stopper handle is raised. May be extended in the direction orthogonal to the longitudinal direction of the hanging bracket body to form an extension, and the extension may hold a stopper handle.

In this case, a spring is provided at the upper end of the stopper handle, and the stopper handle is pressed downward by the spring. Therefore, the stopper handle is naturally lowered by the elastic force of the spring. In addition, the operation of lowering the stopper handle and fixing the stopper in a direction substantially perpendicular to the longitudinal direction of the hanging bracket main body can be easily performed. Also, at this time, since the upper end of the lever guide is extended in a direction orthogonal to the longitudinal direction of the hanging bracket main body to form an extension, and the extension handle holds the stopper handle,
When not used, the extension handle can hold the stopper handle, so that the stopper is not fixed in a direction substantially perpendicular to the longitudinal direction of the hanging member main body.

Further, it is preferable that a jaw is protruded from an outer periphery of the hanging metal body. This makes it possible to effectively prevent the hanging fitting from penetrating the hole and dropping below the iron plate when the hanging fitting is inserted into the hole of the iron plate.
