Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for hoisting building materials such as outer wall materials.

[0002]

2. Description of the Related Art Conventionally, in order to construct a building material such as an outer wall material, a person manually lifts the building material and constructs it at a predetermined position. Further, as another conventional example, a mobile crane is brought to the site, and the construction material is lifted up to a predetermined height by a crane provided for the mobile crane for construction. Further, as another conventional example, a crane device is attached to an upper part of a building frame or an upper part of a scaffold, and a construction material is lifted up to a predetermined height by the crane device for construction.

[0003]

However, in the case where the construction material is manually lifted for construction, a great burden is placed on the operator, and especially when the construction height is gradually increased like the outer wall material, As the lifting height becomes high,
Since it is necessary to place it on a stepladder and lift it up, there is a problem that the work is difficult and the work is dangerous. Further, in the case of using a crane truck, there is a problem that a space for the crane truck to enter the site is required, and it is not possible to deal with the location where the crane truck cannot enter. In addition, in the case where the crane device is attached to the upper part of the building frame or the upper part of the scaffolding, it is necessary to lift and set the crane device equipped with a heavy winch or the like to the upper part of the building structure or the upper part of the scaffolding. When moving the construction site, moving the crane device equipped with a heavy winch or the like in the horizontal direction or the vertical direction at the upper part of the building frame or the upper part of the scaffolding is a work at a high place. It is dangerous and difficult to work, and setting a heavy object on the upper part of the scaffold impairs the stability of the scaffold.

The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to be easily attached to a scaffold or a building frame, and to be set as the construction site moves. It is an object of the present invention to provide a building material hoisting device that is easy and safe to perform.

[0005]

In order to solve the problems of the above-mentioned conventional examples and to achieve the object of the present invention, the building material hoisting device of the present invention can be freely attached to the scaffold 1 or the lower part of the building frame. Wire winding device 3 having attachment / detachment attachment part 2
A wire suspension device 4 having a detachable attachment part 2 that is attachable to the scaffold 1 and the upper part of the building body, and one end of which is attached to the wire winding device 3 and is freely windable to the wire winding device 3. And a wire 7 provided with a mounting means 6 which is suspended around the wire suspension device 4 and is detachably attached to the building material 5 to be suspended at the other end.

Here, it is preferable that the attachment / detachment mounting portion 2 is a clamp device 8 that removably clamps the building material 5.
In addition, it is also preferable that the attachment / detachment mounting portion 2 includes a clamp device 8 that removably clamps the building material 5, and a band-shaped or string-shaped hanging holding member 9 that hangs around the building material 5 to hold it. .

[0007]

Since the present invention is configured as described above, the wire winding device 3 is attached to the bottom of the scaffold 1 or the building frame by the attachment / detachment attachment part 2, and the wire suspending device 4 is attached to the top of the scaffold 1 or the building frame. In a state where the wire 7 having one end attached to the wire winding device 3 is attached by the attachment / detachment attachment part 2 and is suspended around the wire suspension device 4, and the building material 5 is attached to the attachment means 6 provided at the other end of the wire 7. The wire winding device 3 is driven to lift the building material 5 to a desired place. Then, the wire winding device 3 of each of the above devices is used as the scaffolding 1.
When attaching to the building or building skeleton or changing the mounting position, the heavy wire winding device 3 is performed on the scaffolding 1 or the lower part of the building skeleton, so that installation work, re-installation work after moving, etc. can be performed easily on the ground. Moreover, since the attachment work on the scaffold 1 or the upper part of the building frame or the reattachment work after moving can be performed by attaching the wire suspending device 4 having a light weight, the work at a high place can be easily performed. It was

The construction material hoisting device having the above-described structure is used in the scaffolding 1 and the lower part of the building frame (in the embodiment, the pillar 1 of the scaffolding 1).
The wire winding device 3 is attached to the lower part of a by the attachment / detachment attachment part 2. In this case, since the installation work is performed on the ground, even the wire winding device 3 including the heavy motor 11 and the winding drum 12 can be installed much easier than installation at a high place. it can. On the other hand, the wire suspending device 4 is attached / detached to / from the scaffold 1 or the upper part of the building frame (in the embodiment, the upper part of the pillar 1a of the scaffold 1).
Install by. In this case, although the work is performed at a high place such as the upper part of the scaffold 1 or the upper part of the building frame, the suspension device 4 does not include the heavy motor 11, the winding drum 12, and the like, and thus the weight is light. Easy to handle, work in high places can be performed relatively easily and safely.

With the wire winding device 3 attached to the lower part of the scaffold 1 or the building frame and the wire suspending device 4 attached to the upper part of the scaffold 1 or the building frame as described above, the lower operation tool 41 on the ground. Is operated, and the upper operation tool 42 is operated at a high place. In the embodiment shown in the accompanying drawings, an example is shown in which a wall material (horizontally long wall material for horizontal attachment) is hung or hung as the building material 5. That is, the wall material that is the building material 5 is clamped and clamped by the clamp device 8, and the band- or string-shaped hanging holding member 9 is hung around the building material 5 and one end of the hanging holding member 9 is hung. The elastic piece 62 provided at the notched edge portion of the link 61 having the notched portion is bent to hang it from the notch so that the holding member 9 is inserted into the link 61, and the elastic piece 62 is returned to hang it so that the holding member 9 is hung. Of the building material 5 by means of the suspension holding member 9
Is wound and held as shown in FIGS. In this state, the lower operating tool 41 or the upper operating tool 42 is operated to rotate the motor 11 in the forward direction to wind the wire 7 and raise the building material 5. Then, as shown in FIG. 7, the holding member 9 is lifted and hung up to a target position, the holding member 9 is removed, the construction material 5 is nailed to the construction surface 63, and then the clamp by the clamp device 8 is released. In this case, when it is lifted more than the target position, the motor 11 is rotated in the reverse direction to rewind the wire 7 and descend to the target position. During the above-mentioned work, the belt-like or string-like hanging holding member 9 also functions as a safety belt.

During the above operation, according to the present invention,
While operating the lower operation tool 41 to raise, use the upper operation tool 42.
The lowering operation cannot be operated, and the lowering operation tool 41 is performing the lowering operation.
When the upper operation tool 42 is operated, the ascending operation cannot be performed.
When the upper operation tool 42 is being raised, the lower operation tool 41
The lowering operation cannot be operated, and the lowering operation is being performed with the upper operation tool 42.
