Abstract

PURPOSE:To facilitate laying of floor panels by mounting a hanging arm on a pillar temporarily installed between the upper and the lower beams for constructing a house frame body, and moving a winch up and down, and leftward and rightward by means of a traveling device in another rail mounted to a traveling device in the hanging arm. CONSTITUTION:A supporting pillar 3 is temporarily installed between the upper and the lower horizontal frame members F1, F2 of a frame body for constructing a house frame. A freely attachable and detachable hanging arm 4 is mounted on the supporting pillar 3. The hanging arm 4 is provided with a first traveling device 6 which moves along a first rail 5 at right angles to a paper face. There is provided a second traveling device 9 which travels leftward and rightward in a second rail 7 hung from the traveling device 6. The winch of the traveling device 9 hangs each floor panel PS, and sets and fixes the floor panels on given positions by means of the traveling devices 6 and 9. Consequently, the floor panels are laid effectively.

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 carried out inside the frame structure, it is difficult to use a crane or the like to move and lift the floor panels to each laying position. Movement and alignment are being performed.

[Invention tries to solve it! II! ! However, the laying work needs to be done accurately and over a wide area over the entire floor surface by butting the edges of the floor panels together, and since the floor panels themselves are large and heavy, conventional manual work is not possible. In some cases, it takes a lot of effort and time, etc.
Work efficiency will be greatly reduced. 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 support column installed between upper and lower frame members, and a first traveling tool that moves the first rail tool in the direction of the frame member. The laying of floor panels is basically carried out using a second rail device that is supported at right angles to the first rail device, and a second traveling device that has a winch and moves the second rail device. The object of the present invention is to provide a lifting tool that can significantly improve construction efficiency and solve the aforementioned problems.

[Means to solve the problem]

In order to achieve the above object, the lifting tool of the present invention is removable between a horizontal upper frame member of a house frame structure and a lower frame member below the core frame member and parallel to the core frame member. A hanging arm that can be detachably attached to an erected support column and has a rail holder, and a long arm that straddles the plurality of hanging arms and is arranged in the direction of the frame member and supported by the rail holder. a first rail tool; a first running tool that is held by the first rail tool and is movable in the direction of the frame member, and a second rail tool that is perpendicular to the first rail tool can be attached; a second rail movable with a winch;
and a lifting device having a running device.

[Effect]

The lifting tool configured in this way includes a support pillar erected between the bridges, a first rail tool that is supported via a hanging arm that is detachably attached to the support pillar, and a first rail tool that is supported by the first rail tool. A second rail tool is provided which is supported perpendicularly to the first rail tool via a first running tool that moves along the second rail tool.
Since the second traveling tool having a winch is movably disposed on the rail tool, the winch can be moved vertically and horizontally.

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 to being able to prevent floor panels from falling during the entire process, safety can be greatly improved.
