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, thereby significantly improving the construction efficiency of the outer wall panel. Uru lifting equipment.

[Conventional technology]

For example, in a dry construction building, its outer wall is formed by sequentially incorporating outer wall panels, such as concrete panels, between the outer surfaces of the prefabricated frame structure of the house or between the frame structures. 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 the entire outer surface is erected, many times in the width direction of the winch. It is necessary to change the position, and to attach and detach it for that purpose, greatly reducing the lifting work efficiency. Note that the work is inferior in safety because it is performed at a high place. Moreover, since the lifting position is fixed in this product, 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 construction to align the joint width. Yes There is a problem that a great deal of labor is required for construction work and position adjustment.

It is an object of the present invention to provide a hoisting tool that can easily and securely attach a rail tool that movably hangs a winch to a horizontal material for forming a scaffold, and can greatly improve the construction efficiency of construction. I am trying.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a hoisting tool of the present invention is a tubular and lateral scaffold for scaffolding, which is arranged along the outer peripheral surface of a house under construction, parallel to the inner surface facing the outer peripheral surface and the outer side thereof and horizontally. A lifting tool to be attached to a material, the extension piece extending to the lower surface of the outer horizontal member at the outer end of a base rod having a rail mounting portion for fixing a rail tool for movably suspending a winch at an inner end. And a recess for inserting an inner horizontal member is provided between the extension piece and the rail mounting portion and on the lower surface of the base rod.

[Action]

The hoisting tool configured in this manner uses a tool for the horizontal member by bringing the extension piece at the rear end of the base rod into contact with the lower surface of the outer lateral member and fitting the recess into the inner member. It can be fixed with one touch without making it easy to attach and detach.
Further, by fixing the rail tool to the rail mounting portion at the inner end of the base rod, the winch can be freely moved along the rail tool, and the wall panel can be easily lifted at the built-in position as required. .

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

In addition, even if the rail tool is formed to be shorter than the full width of the outer peripheral surface, the base rod is supported like a lever with the recess as a fulcrum, so it is safe with the rail tool attached. Further, the position can be easily changed in the width direction, and even when the position is changed by removing the rail member, the work of changing the position can be efficiently performed because the attachment and detachment of the base rod and the horizontal member are made in one touch.
