Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of efficiently constructing an outer wall panel such as a concrete panel on the outer surface of a frame structure of a house, and greatly improves the efficiency of constructing an outer wall panel. Related to possible lifting equipment.

[Conventional technology]

For example, in a dry construction building, the outer wall thereof is formed by sequentially building outer wall panels such as concrete panels between the outer surface of the frame structure of the house or between the frame members. Therefore, each outer wall panel is required to be lifted in accordance with its built-in position.

[Problems to be Solved by the Invention]

However, since such a hoisting is conventionally performed by using a winch that is immovably fixed to the frame structure of the house or its scaffolding material, when constructing over the entire width of the outer surface, many times in the width direction of the winch. It is necessary to change and fix the position, which greatly reduces the lifting work efficiency. Note that the work is inferior in safety because it is performed at a high place. Moreover, since the hoisting position of this product is fixed, it is necessary to support the weight of the outer wall panel by the operator when adjusting the position of the outer wall panel in the width direction at the time of building to align the joint width. Yes There is a problem that a lot of labor is required for construction work and position adjustment.

The present invention uses a rail tool that can be moved between suspension arms that are attached to a scaffolding member at a distance without being separated from a suspension arm, and a traveling tool for mounting a winch that runs along the rail tool. Basically, it is an object of the present invention to provide a hoisting tool capable of greatly improving the efficiency of construction work and solving the above problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the lifting tool of the present invention is attached to a scaffolding material arranged along the outer peripheral surface of a house under construction at a substantially constant interval and arranged at a right angle to the outer peripheral surface. A suspension arm having a rail receiver, a rail tool supported by the rail receiver, and having a length longer than that of the three suspension arms and capable of moving between the suspension arms without being detached from the suspension arm, and the rail tool. And a traveling tool for attaching a winch, the suspension arm includes a guide piece extending in a direction orthogonal to the outer peripheral surface, and the rail receiver allows the guide piece to move.

[Action]

The hoisting tool configured in this manner has the hoisting arm attached to the scaffolding along the outer peripheral surface of the house being built, and the railing tool for guiding the traveling tool is arranged between the hoisting arms. The winch can be freely moved along with the traveling tool along the outer peripheral surface. Therefore, the outer wall panel can be lifted at each built-up position without changing the position of the winch a plurality of times and fixing the winch, and the lifting work efficiency can be improved.

Moreover, even when adjusting the position in the width direction during construction,
Since the traveling tool can be moved right above the erected position, the weight of the outer wall panel can be supported by the winch over the entire work, and the erection work can be performed efficiently without labor.

In addition, since this rail tool can move between the suspension arms without being disengaged from the suspension arms, it is possible to construct the entire outer peripheral surface with a short rail tool, and the overall lifting equipment is small and lightweight. It can be easily formed and removed, and its usability can be improved.

Further, a guide piece extending in a direction orthogonal to the outer peripheral surface of the house is provided on the suspension arm, and the rail receiver is movably guided by the guide piece, so that the winch can be moved closer to the outer peripheral surface, and the outer wall panel is It can be safely lifted without colliding with the outer peripheral surface and the like, and the weight of the outer wall panel can be supported by the winch over the entire construction work, so that the work can be performed more efficiently.
