Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention enables efficient laying of floor panels, such as concrete panels, on the frame structure of a house, and greatly improves the efficiency of laying floor panels. Regarding Uru lifting equipment.

[Conventional technology]

For example, in a building using the dry method method, the floor is formed by sequentially dispersing floor panels, such as concrete panels, between the floor beams of a pre-framed house frame structure.

On the other hand, since this type of laying work is done inside the frame structure, it requires moving the floor panels to each laying position using a crane, etc.
Lifting is difficult, so floor panels have traditionally been moved and aligned manually by workers.

[Invention or problem to be solved]

However, the laying work needs to be carried out over a wide area over the entire floor surface, with the edges of the floor panels butted together, and also because the floor panels themselves are large and heavy.
Conventional manual methods require a great deal of labor and time, which greatly reduces work efficiency. In addition, this method requires work at heights and has unstable scaffolding, making it less safe.Therefore, in recent years, new technologies have been developed that can improve construction efficiency in this type of laying work, reduce labor, and improve safety. There was a strong desire for a new tool to emerge.

The present invention provides a first rail tool that straddles between hanging arms attached to a beam material, and a first rail tool that moves the first rail tool in the direction of the beam material at right angles to the first rail tool. Second supported
The above-mentioned problems can be solved by basically using a second rail tool and a second traveling tool that has a winch and moves the second rail tool, and the efficiency of laying floor panels can be greatly improved. The purpose is to provide lifting equipment.

[Means to solve the problem]

In order to achieve the above object, the lifting tool of the present invention includes a lifting arm that can be detachably attached to a horizontal beam of a house frame structure and has a rail receiver, and a lifting tool that straddles a plurality of lifting arms in the direction of the beam. a long first rail tool arranged and supported by the rail receiver; and a long rail tool that is held by the first rail tool, movable in the direction of the beam material, and perpendicular to the first rail tool. The present invention includes a first traveling implement capable of attaching a second rail implement, and a second traveling implement capable of moving the second rail implement and having a winch.

[Effect]

The lifting tool configured in this way includes a first rail tool that is supported by a beam member via a lifting arm, and a first rail tool that moves along the first rail tool. A second rail tool supported at right angles to the tool is provided, and a second traveling tool having a winch is movably disposed on the second rail tool, so that the winch can be moved vertically and horizontally. be able to.

Therefore, while it can be conveniently attached to the frame structure, the winch can be used to quickly suspend and move floor panels to each laying position without requiring any effort, making the laying work efficient and highly accurate. In addition, it is possible to prevent floor panels from falling during the entire operation, greatly improving safety.
