However, the load acting at the time of lifting is a temporary load, and if reinforcement is performed according to the load, the rigidity may become excessive after installation in the building. Further, when joining to an adjacent structure, the entire circumference of the panel may not be surrounded by the frame material.

Therefore, an object of the present invention is to provide a panel transport jig and a panel transport method that can withstand a load that temporarily acts during transport.

In order to achieve the above object, the panel transport jig of the present invention is a panel transport jig in which a plate material is attached to the upper surface of beams arranged at intervals of substantially parallel, and the panel is , Both ends of the beam are open, and the transport beam is crossed at both ends of the beam in the direction orthogonal to the axis of the beam, and a plurality of the small beams attached to the side surface of the transport beam. It is characterized by being provided with a support metal fitting that is inserted into the opening of the beam.

Here, at least one end of the transport beam may be joined to the end of the beam via a fixing bracket. Further, the support metal fitting may be an L-shaped metal fitting having an eaves-shaped upper surface.

The invention of the panel transport method is a panel transport method using the transport jig of any of the above panels, and the support metal fittings attached to the side surface of the transport beam with respect to the opening of the beam. By inserting each of the above, the step of attaching the transport jig to both side edges of the panel, the step of transporting the panel to which the transport jig is attached to the destination, and the step of transporting the panel to which the transport jig is attached to the transport beam at the destination. It is characterized by including a step of connecting wires to lift the panel and installing the panel at a predetermined position, and a step of removing the transport jig after the panel is installed.

The transport jig of the panel of the present invention configured in this way is a panel in which a panel to be transported is a panel in which a plate material is attached to the upper surface of a beam arranged at intervals of substantially parallel to the beam. Both ends of the beam are open. In other words, the panel to be transported does not have a frame member arranged on the side edge oriented in a direction substantially orthogonal to the beam.

Such a panel has lower rigidity than a panel in which the entire circumference of the side edge is surrounded by a frame material, but in the transport jig of the panel of the present invention, the transport beam is oriented substantially orthogonal to the girder. It functions as a frame material placed on the facing side edge.

Therefore, it is possible to counter the load temporarily acting during transportation. Further, this transport jig is economical because it can be collected and reused after the panel is installed at a predetermined position.

Further, if at least one end of the transport beam is joined to the end of the beam via a fixing bracket, it is possible to reliably prevent the transport jig from coming off at an unintended timing.

Further, if the upper surface of the support metal fitting is projected in the shape of an eave, the load of the panel can be supported by the eaves-shaped part inserted in the opening of the beam, and the joining work is not required. , It becomes possible to easily install and remove.

Then, according to the panel transportation method of the present invention, the panel can be temporarily reinforced during transportation, and the transportation jig can be collected after the panel is installed, so that the number of panel members and the assembly man-hours can be reduced.
